Financial constraints and innovation: Why poor countries don't catchup

Abstract:

We examine micro-level channels of how financial development can affect macroeconomic outcomes like the level of income and export intensity. We investigate theoretically and empirically how financial constraints affect a firm's innovation and export activities, using unique firm survey data which provides direct measures for innovations and firm-specific financial constraints. We find that financial constraints restraint heability of domestically owned firms to innovate and export and hence to catch up to the technological frontiers. This negative effect is amplified as financial constraints force export and innovation activities to become substitutes although they are generally natural complements.

Exports Versus FDI Revisited: Does Finance Matter?

Abstract:

This paper explores the impact of financial constraints on the  internationalization strategies of firms. It contributes to the literature by focusing on three aspects: First, the paper studies the impact of financial constraints on exporting relative to FDI. Consistent with theory, the empirical results confirm  that the impact of financial constraints is stronger for FDI than for exporting. Second, the paper analyzes the extensive and the intensive margins and finds that financial frictions matter for  both. Third, the paper explores the impact on manufacturing as compared to service industries and shows that firms in service industries are affected more than firms in manufacturing. The paper also identifies a threshold effect: Financial constraints do not matter  for small firms whose productivity seems to be too low to consider international expansions.

On Competition and the Strategic Management of Intellectual Property in Oligopoly

Abstract:

An innovative firm with private information about its indivisible process innovation chooses strategically whether to apply for a patent with probabilistic validity or rely on secrecy. By doing so, the firm manages its rivals’ beliefs about the size of the innovation, and affects the incentives in the product market. A Cournot competitor tends to patent big innovations, and keep small innovations secret, while a Bertrand competitor adopts the reverse strategy. Increasing the number of firms gives a greater (smaller) patenting incentive for Cournot (Bertrand) competitors. Increasing the degree of product substitutability increases the incentives to patent the innovation.

Heterogeneous Contestants and Effort Provision in Tournaments - an Empirical Investigation with Professional Sports Data

Abstract:

We empirically investigate if tournaments between heterogeneous contestants are less intense. To test our hypotheses we use professional sports data from the TOYOTA Handball-Bundesliga, the major handball league in Germany. Using either differences in betting odds or rankings to measure ability differences, our results support standard tournament theory as we find a highly significant negative impact of the matchup's heterogeneity on joint teame efforts. However, further analysis shows that this overall decrease in efforts is almost entirely driven by the reaction of the ex-ante favorite team.

Exports and Productivity: An Empirical Analysis of German and Austrian Firm-Level Performance

Abstract:

This paper studies the relationship between export activities and firm-level productivity. Unique matching of German and Austrian micro data from 1994 to 2003 suggests that exporters are more productive by around 40 percent compared with non-exporters. Moreover, beside other analysis techniques,
instrumental variable estimations suggest that exporting causes a rise in firm-level productivity. That is, the annual average growth rate of an exporting firm's productivity is between about 1 and 1.5 percent higher than that of non-exporters. It allows the conclusion that, against other findings of existing studies, both directions hold: more productive firms self-select themselves into export markets and being active in foreign markets boosts firm-level productivity.

Tariff Rates, Offshoring and Productivity: Evidence from German and Austrian Firm-Level Data

Abstract:

This paper studies the impact of trade liberalization in terms of tariff cuts within the Eastern European enlargement on German and Austrian firm productivity. Unique matching of data from 1994 to 2003 suggests that tariff reductions raise parent firm productivity significantly. A ten percentage point decrease in tariff rates can lead to total factor productivity gains of up to 2 percent. The data allow distinction between three types of tariffs: output, intra-firm and input tariff rates. The size of the results strongly depends on the type of tariff and country analyzed.

Innovation and the International Firm Structure: Theory and Evidence from German Firm-Level Data

Abstract:

This paper studies the impact of innovation on the organizational structure. The theoretical framework predicts that a larger parental pool of knowledge raises the probability of offshoring. This holds in a national as well as an international context. However, when the producer loses territorial protection, the changeover from non-integration to integration is delayed. Employing data on German firms investing in Eastern Europe finds empirical evidence for the theoretical predictions. The results are robust to different measurements and an instrumental variable regression.

Incentive Effects in Asymmetric Tournaments Empirical Evidence from the German Hockey League

Abstract:

Following tournament theory, incentives will be rather low if the contestants of  a tournament are heterogeneous. We empirically test this prediction using a  large dataset from the German Hockey League. Our results show that indeed the intensity of a game is lower if the teams are more heterogeneous. This effect can be observed for the game as a whole as well as for the ?rst and last third. When dividing the teams in the dataset into favorites and underdogs, we only observe a reduction of effort provision from favorite teams. As the number of games per team changes between different seasons, we can also investigate the effect of a changing spread between winner and loser prize. In line with theory, teams reduce effort if the spread declines. Interestingly, effort is also sensitive to the total number of teams in the league even if the price spread remains unchanged.

Creditor Rights and Debt Allocation within Multinationals

Abstract:

We analyze the optimal debt structure of multinational corporations choosing between centralized or decentralized borrowing. We identify how this choice is affected by creditor rights and bankruptcy costs, taking into account managerial incentives and coinsurance considerations. We find that partially centralized borrowing structures are optimal with either weak or strong creditor rights. For intermediate levels of creditor rights fully decentralized (centralized) borrowing structures are optimal if managers have strong (weak) empire building dencies. Decentralized borrowing is more attractive for companies focussing on short-term profitability. Credits are rather taken in countries with better creditor rights and more efficient insolvency systems.

Group Lending versus Individual Lending in Microfinance

Abstract:

Microfinance is typically associated with joint liability of group members. However, a large part of microfinance institutions rather offers individual instead of group loans. We analyze the incentive mechanisms in both individual and group contracts. Moreover, we show that microfinance institutions offer group loans when the loan size is rather large, refinancing costs are high, and competition between microfinance institutions is low. Otherwise, individual loans are offered. Interestingly, our analysis predicts that individual lending in microfinance will gain in importance in the future if microfinance institutions continue to get better access to capital markets and if competition further rises.

Competitive Careers as a Way to Mediocracy

Abstract:

We show that incompetitive careers based on individual performance the least productive individuals may have the highest probabilities to be promoted to top positions. These individuals have the lowest fall-back positions and, hence, the highest incentives to succeed in career contests. This detrimental incentive effect exists irrespective of whether effort and talent are substitutes or complements in the underlying contest-success function. However, in case of complements the incentive effect may be be outweighed by a productivity effect that favors high    effort choices by the more talented individuals.

On the Use of Information in Repeated Insurance Markets

Abstract:

We analyze the use of information in a repeated oligopolistic insurance
market. To sustain collusion, insurance companies might refrain from
changing their pricing schedules even if new information about risks
becomes available. We therefore provide an explanation for the existence
of "unused observables" that is information which a) insurance companies
collect or could collect, b) is correlated with the risk experience, but
c) is not used by companies to set prices. Furthermore, the existence of
bulk discounts becomes rationalizable. These results also obtain if we
include communication among companies and market entry to our framework.

Financial Constraints and the Margins of FDI

Abstract:

Recent literature on multinational firms has stressed the importance of low productivity as a barrier to the cross-border expansion of firms. But firms may also need external finance to shoulder the costs of entering foreign markets. We develop a model of multinational firms facing real and financial barriers to foreign direct investment (FDI), and we analyze their impact on the FDI decision (the extensive margin) and foreign affiliate sales (the intensive margin). We provide empirical evidence based on a detailed dataset of German multinationals which contains information on parent-level and affiliate-level financial constraints as well as on the location the foreign affiliates. We find that financial factors constrain firms’ foreign investment decisions, an effect  felt in particular by large firms. Financial constraints at the parent level matter for the extensive, but less  so for the intensive margin. For the intensive margin, financial constraints at the affiliate level are relatively more important.

Sabotage in dynamic tournaments

Abstract:

This paper studies sabotage in a dynamic tournament. Three players compete in two rounds. In the final round, a player who is leading in the race, but not yet beyond the reach of his competitors, gets sabotaged more heavily. As a consequence, if players are at the same position initially, they do not work productively or sabotage at all in the first round. Thus sabotage is not only directly destructive, but also depresses incentives to work productively. If players are heterogeneous ex ante, sabotage activities in the first round may be concentrated against an underdog, contrary to findings from static tournaments. We also discuss the robustness of our results in a less stylized environment.

On the legitimacy of coercion for the nancing of public goods

Abstract:

The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay for public goods that they do not value. It is shown that participation constraints are desirable if public goods are provided by a malevolent Leviathan. By contrast, with a Pigouvian planner, efficiency can be achieved. Finally, the paper studies the delegation of public goods provision to a profit-maximizing firm. This also makes participation constraints desirable.

Minimum Wages and Excessive Effort Supply

Abstract:

It is well-known that, in static models, minimum wages generate
positive worker rents and, consequently, inefficiently low effort. We
show that this result does not necessarily extend to a dynamic context.
The reason is that, in repeated employment relationships, firms may
exploit workers’ future rents to induce excessively high effort.

Integrating with Their Feet: Cross-Border Lending at the German-Austrian Border

Abstract:

The current economic policy discussion on financial integration in the European Union concentrates on cross-border mergers. We study the impact of cross-border lending in a theoretical model where banks acquire either hard or soft information on borrowing firms and predict that the closer firms are to the border the more likely banks are to offer them cross-border loans. This hypothesis is confirmed in the ifo Business Climate Survey that reports the perceptions of German firms on banks� lending behavior between 2003 and 2006. In contrast to the policy of harmonization, differences in bank regulations may provide incentives for cross-border lending. Thus, we show that financial integration may take place from the bottom up.

Relative Performance Pay, Bonuses, and Job-Promotion Tournaments

Abstract:

Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We explain these empirical puzzles by combining job-promotion tournaments with higher-level bonus payments in a two-tier hierarchy. Moreover, we show that under certain conditions the firm implements first-best effort on tier 2 although workers earn strictly positive rents. The reason is that the firm can use second-tier rents for creating incentives on tier 1. If workers are heterogeneous, the firm strictly improves the selection quality of a job-promotion tournament by employing a hybrid incentive scheme that includes bonus payments.

Bank Competition - When is it Good?

Abstract:

The effects of bank competition and institutions on credit markets are usually studied separately although both factors are interdependent. We study the effect of bank competition on the choice of contracts (screening versus collateralized credit contract) and explicitly capture the impact of the institutional environment. Most importantly, we show that the effects of bank competition on collateralization, access to finance, and social welfare depend on the institutional environment. We predict that firms' access to credit increases in bank competition if institutions are weak but bank competition does not matter if they are well-developed.

Optimal Contracts for Lenient Supervisors

Abstract:

We consider a situation where an agent's effort is monitored by a supervisor who cares for the agent's well being. This is modeled by incorporating the agent's utility into the utility function of the supervisor. The first best solution can be implemented even if the supervisor's preferences are unknown. The corresponding optimal contract is similar to what we observe in practice: The supervisor's wage is constant and independent of his report. It induces one type of supervisor to report the agent's performance truthfully, while all others report favorably independent of performance. This implies that overstated performance (leniency bias) may be the outcome of optimal contracts under informational asymmetries.

How to Determine whether Regional Markets are Integrated? Theory and Evidence from European Electricity Markets

Abstract:

Prices may di er between regional markets if transport capacities are limited. We develop a new approach to determine to which extent such di erences stem from limited participation in cross-border trader rather than from bottlenecks. We derive a theoretical integration benchmark for the typical case where transportation markets clear before the product markets, using Grossman's (1976) notion of a rational expectations equilibrium. We compare the benchmark to data from European electricity markets. The data reject the integration hypothesis: Capacity prices contain too little information about spot price di erential; this indicates that well informed traders do not engage in cross-border trade.

Optimal Tournament Contracts for Heterogeneous Workers

Abstract:

We analyze the optimal design of rank-order tournaments with heterogeneous workers. Iftournament prizes do not differ between the workers(uniform prizes), as in the previous tournament literature, the outcome will be ineffcient. In the case of limited liability, the employer may benefit from implementing more than first-best effort. We show that the employer can use individual prizes that satisfy a self-commitment condition and induce effcient incentives at the same time, thus solving a fundamental dilemma in tournament theory. Individual prizes exhibit two major advantages - they allow the extraction of worker rents and the adjustment of individual incentives, which will be important for the employer if he cannot rely on handicaps.

Risk Taking in Winner-Take-All Competition

Abstract:

We analyze a two-stage game between two heterogeneous players. At stage one, common risk is chosen by one of the players. At stage two, both players observe the given level of risk and simultaneously invest in a winner-take-all competition. The game is solved theoretically and then tested by using laboratory experiments. We find three effects that determine risk taking at stage one - an effort effect, a likelihood effect and a reversed likelihood effect. For the likelihood effect, risk taking and investments are clearly in line with theory. Pairwise comparison shows that the effort effect seems to be more relevant than the reversed likelihood effect when taking risk.

Limited Liability and the Risk-Incentive Relationship

Abstract:

Several empirical ?ndings have challenged the traditional view on the trade-off between risk and incentives. By combining risk aversion and limited liability in a standard principal-agent model the empirical puzzle on the positive relationship between risk and incentives can be explained. Increasing risk leads to a less informative performance signal. Under limited liability, the principal may optimally react by increasing the weight on the signal and, hence, choosing higher-powered incentives.

A Model of Vertical Oligopolistic Competition

Abstract:

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the upstream conditions mainly affect the distribution of profits. We compare the welfare effects of upstream versus downstream deregulation policies and show that the impact of deregulation may be overvalued when ignoring feedback effects from the other market. Furthermore, we analyze how different forms of vertical restraints influence the endogenous market structure and show when they are welfare enhancing.

Corporate Hierarchies and the Size of Nations: Theory and Evidence

Abstract:

Corporate organization varies within a country and across countries with country size. The paper starts by establishing some facts about corporate organization based on unique data of 660 Austrian and German corporations. The larger country (Germany) has larger firms with flatter and more decentralized corporate hierarchies compared to the smaller country (Austria). Firms in the larger country change their organization less fast than firms in the smaller country. Over time firms have been introducing less hierarchical organizations by delegating power to lower levels of the corporation. We develop a theory which explains these facts and which links these features to the trade environment that countries and firms face. We introduce firms with internal hierarchies in a Krugman (1980) cum Melitz and Ottaviano (2007) model of trade. We show that international trade and the toughness of competition in international markets induce a power struggle in firms which eventually leads to decentralized corporate hierarchies. We offer empirical evidence which is consistent with the models predictions.

The Politician and his Banker

Abstract:

Should the European Union grant state aid through an institution like the European Investment bank? This paper evaluates the efficiency of different measures for granting state aid. We use a theoretical model with firms that differ in their creditworthiness and compare different types of subsidies with indirect subsidization through public banks. We find that, in a large parameter range, the politician prefers public banks to direct subsidies because they avoid windfall gains to entrepreneurs and they economize on screening costs. For similar reasons, they may increase social welfare relative to subsidies. One important prerequisite for this result is that public banks must not be allowed to fully compete with private banks. However, from a welfare perspective, a politician uses public banks inefficiently often.

Feedback in Tournaments under Commitment Problems: The-ory and Experimental Evidence

Abstract:

In this paper, we analyze a principal's optimal feedback policy in tournaments. We close a gap in the literature by assuming the principal to be unable to commit to a certain policy at the beginning of the tournament. Our analysis shows that in equilibrium the principal reveals in-termediate information regarding the agents’ previous performances if these performances are not too different. Moreover, we investigate a situation where the principal is not able to credi-bly communicate her information. Having presented our formal analysis, we test these results using data from laboratory experiments. The experimental findings provide some support for the model.

The Effect of Bank Competition on the Bank’s Incentive to Collateralize

Abstract:

It has been argued that competing banks make inefficiently frequent use of collateralization in situations where they are better able to evaluate a project’s risk than entrepreneurs. We study the bank’s choice between screening and collateralization in a model where banks do not have this superior screening skill. In particular, we study the effect of bank competition on this choice. We find that competing banks use collateral less often than a monopolistic bank because competition will intensify if both banks collateralize. Moreover, bank competition is welfare improving if collateralization is rather costly.

Double-Sided Moral Hazard, Efficiency Wages and Litigation

Abstract:

We consider a double-sided moral hazard problem where each party can renege on the signed contract since there does not exist any verifiable performance signal. It is shown that ex-post litigation can restore incentives of the agent. Moreover, when the litigation can be settled by the parties the pure threat of using the legal system may suffice to make the principal implement first-best effort. As is shown in the paper, this .finding is rather robust. In particular, it holds for situations where the agent is protected by limited liability, where the parties have different technologies in the litigation contest, or where the agent is risk averse.

Who is Afraid of Political Risk? Multinational Firms and their Choice of Capital Structure

Abstract:

This paper investigates how multinational firms choose their capital structure in response to political risk. We focus on two choice variables, the leverage and the ownership structure of the foreign affiliate, and we distinguish different types of political risk, like expropriation, corruption and confiscatory taxation, and In our theoretical analysis we find that as political risk increases the ownership share always decreases whereas leverage can both increase or decrease, depending on the type of political risk. Using the Microdatabase Direct Investment of the Deutsche Bundesbank, we find supportive evidence for these different effects.

FDI and Domestic Investment: An Industry-Level View

Abstract:

Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intrasector effects. For inward FDI, inter-sector linkages matter as well.

Allocation of Authority when a Person is not a Robot

Abstract:

We formalize a conception of authority, which is commonly defined as the right of controlling a person’s actions embedded in human assets in sociology. Due to the inalienable property of human assets, the contractible formal authority is hard to verify and enforce, while real authority usually diverges from formal authority. Inefficiency tends to arise when a task is not routine or can not be done by a robot. Using a framework of incomplete contract, we show that allocation of formal authority, as an instrument to mitigate the inefficiency, is determined by features of tasks and specificity of assets, and the relationship between the resources. Monitoring is then introduced to fine tune value of delegation.

Power in the Multinational Corporation in Industry Equilibrium

Abstract:

Recent theories of the multinational corporation introduce the property rights model of the firm and examine whether to integrate our outsource firm activities locally or to a foreign country. This paper focus instead on the internal organization of the multinational corporation by examining the power allocation between headquarters and subsidiaries. We provide a framework to analyse the interaction between the decision to serve the local market by exporting or FDI, market acces and the optimal mode of organization of the multinational corporation. We find that subsidiary managers are given most autonomy in their decision how to run the firm at intermediate levels of local competition. We then provide comparative statics for changes in fixed FDI entry costs and trade costs, information technology, the number of local competitors, and in the size of the local market.

Short-term or long-term contracts? - A rent-seeking perspective

Abstract:

In this paper, .rms engage in rent seeking in order to be assigned a governmental contract. We analyze how a change in the contract length a¤ects the .rms. rent-seeking behavior. A longer contract leads to more rent seeking at a contract assignment stage, as the .rms value the contract higher. On the other hand, the contract has to be assigned less often, which of course leads to less rent seeking. Finally, a longer contract makes a possible cooperation between the .rms solving the rent-seeking problem more difficult to sustain.

Competing in Organizations: Firm Heterogeneity and International Trade

Abstract:

This paper develops a theory which investigates how firms’ choice of corporate organization is affecting firm performance and the nature of competition in international markets. We develop a model in which firms’ organisational choices determine heterogeneity across firms in size and productivity in the same industry. We then incorporate these organisational choices in a Krugman cum Melitz and Ottaviano model of international trade. We show that the toughness of competition in a market depends on who - headquarters or middle managers - have power in firms. Furthermore, we propose two new margins of trade adjustments: the monitoring margin and the organizational margin. International trade may or may not lead to an increase in aggregate productivity of an industry depending on which of these margins dominate. Trade may trigger firms to opt for organizations which encourage the creation of new ideas and which are less well adapt to price and cost competition.

Variance analysis and linear contracts in agencies with distorted performance measures

Abstract:

Keywords: This paper investigates the role of variance analysis procedures in aligning objectives under the condition of distorted performance measurement. A riskneutral agency with linear contracts is analyzed, whereby the agent receives postcontract, pre-decision information on his productivity. If the performance measure is informative with respect to the agent’s marginal product concerning the principal’s objective, variance investigation can alleviate effort misallocation. These results carry over to a participative budgeting situation, but in this case the variance investigation procedures are less demanding.

Bonus Pools, Limited Liability, and Tournaments

Abstract:

Tournaments have been objected as resulting from ad hoc restrictions to the contracting problem which are not easily justified. Taking into account that a performance measure might not be verifiable to a third party, however, a restriction to payments which sum up to a constant may be reasonable. The paper analyzes such fixed payment schemes with regard to their optimality and the relation to the special case of tournaments. It emerges that for a group of identical risk-neutral agents, the optimal fixed payment scheme is a tournament.

Performance measure congruity in linear agency models with interactive tasks

Abstract:

This note demonstrates how performance measure congruity and noise determine an agency’s total surplus within an linear agency framework with multiple tasks. It provides a decomposition of agency costs, leading back to a congruity index previously proposed in the literature. In addition, it generalizes this index to a more general cost function, thereby highlighting the context specificity of the original criterion. Finally, it suggests a redefinition of tasks under which the criterion prevails.

Distorted performance measurement and relational contracts

Abstract:

This paper analyzes the use of alternative performance measures in an agency model in which contracting incorporates both formal and informal agreements. It is shown that under a proper use of verifiable and unverifiable performance measures, the two types of contracts are complements, regardless of the principal’s fallback position. The analysis therefore contrasts earlier results of the literature, and provides a rationale for the application of subjective performance information, as it is frequently incorporated in strategic performance measurement systems.

Optimal Risk Taking in an Uneven Tournament Game with Risk Averse Players

Abstract:

We analyze the optimal choice of risk in a two-stage tournament game between two players that have different concave utility functions. At the first stage, both players simultaneously choose risk. At the second stage, both observe overall risk and simultaneously decide on effort or investment. The results show that those two effects which mainly determine risk taking — an effort effect and a likelihood effect — are strictly interrelated. This finding sharply contrasts with existing results on risk taking in tournament games with symmetric equilibrium efforts where such linkage can never arise. Hence, previous findings based on symmetry at the effort stage turn out to be nongeneric.

Two Tales on Resale

Abstract:

In some markets vertically integrated firms sell directly to final customers hut also to independent downstream firms with whom they then compete on the downstream market. It is often argued that resellers intensify competition and benefit consumers, in particular when wholesale prices are regulated. However, we show that (i) resale may increase prices and make consumers worse off and that (ii) standard "retail minus X regulation" may increase prices and harm consumers. Our analysis suggests that this is more likely if the number of integrated firms is small, the degree of product differentiation is low, and/or if competition is spatial.

The Performance of Private Equity Funds: Does Diversification Matter?

Abstract:

This paper is the first systematic analysis of the impact of diversification on the performance of private equity funds. A unique data set allows the exact evaluation of diversification across the dimensions financing stages, industries, and countries. Very different levels of diversification can be observed across sample funds. While some funds are highly specialized others are highly diversified. The empirical results show that the rate of return of private equity funds declines with diversification across financing stages, but increases with diversification across industries. Accordingly, the fraction of portfolio companies which have a negative return or return nothing at all, increase with diversification across financing stages. Diversification across countries has no systematic effect on the performance of private equity funds.

Cluster Performance reconsidered: Structure, Linkages and Paths in the German Biotechnology Industry, 1996-2003

Abstract:

This paper addresses the evolution of biotechnology clusters in Germany between 1996 and 2003, paying particular attention to their respective composition in terms of venture capital, basic science institutions and biotechnology firms. Drawing upon the significance of co-location of "money and ideas", the literature stressing the importance of a cluster's openness and external linkages, and the path dependency debate, the paper aims to analyse how certain cluster characteristics correspond with its overall performance. After identifying different cluster types, we investigate their internal and external interconnectivity in comparative manner and draw on changes in cluster composition. Our results indicate that the structure, i.e. to which group the cluster belongs, and the openness towards external knowledge flows deliver merely unsystematic indications with regard to a cluster's overall success. Its ability to change composition towards a more balanced ratio of science and capital over time, on the other hand, turns out as a key explanatory factor. Hence, the dynamic perspective proves effective illuminating cluster growth and performance, where our explorative findings provide a promising avenue for further evolutionary research.

Mergers, Litigation and Efficiency

Abstract:

We consider antitrust enforcement within the adversarial model used by the United States. We show that, under the adversarial system, the Antitrust Authority may try to prohibit mergers also in those cases in which litigation is inefficient. Even if market concentration and technological disadvantages lead to a significant welfare reduction after merger, from society’s perspective the agency’s lawsuit may be inefficient. We can show that these inefficiencies may be aggravated if the takeover is hostile.

Jostling for Advantage: Licensing and Entry into Patent Portfolio Races

Abstract:

Licensing in a patent thicket allows firms to either avoid or resolve hold-up. Firms' R&D incentives depend on whether they license ex ante or ex post. We develop a model of a patent portfolio race, which allows for endogenous R&D efforts, to study firms' choice between ex ante and ex post licensing. The model shows that firms' relationships in product markets and technology space jointly determine the type of licensing contract chosen. In particular, product market competitors are more likely to avoid patent portfolio races, since the threat of hold-up increases. On the other hand, more valuable technologies are more likely to give rise to patent portfolio races. We also discuss the welfare implications of these results.

Project Finance as a Risk-Management Tool in International Syndicated Lending

Abstract:

We develop a double moral hazard model that predicts that the use of project finance increases with both the political risk of the country in which the project is located and the influence of the lender over this political risk exposure. In contrast, the use of project finance should decrease as the economic health and corporate governance provisions of the borrower’s home country improve. When we test these predictions with a global sample of syndicated loans to borrowers in 139 countries, we find overall support for our model and provide evidence that multilateral development banks act as “political umbrellas”.

Acquisition versus greenfield: The impact of the mode of foreign bank entry on information and bank lending rates

Abstract:

Policy makers often decide to liberalize foreign bank entry but at the same time restrict the mode of entry. We study how different entry modes affect the interest rate for loans in a model in which domestic banks possess private information about their incumbent clients but foreign banks have better screening skills. Our model predicts that competition is stronger if market entry occurs through a greenfield investment and therefore domestic banks' interest rates are lower. We find empirical support for our results for a sample of banks from ten Eastern European countries for the period 1995-2003.

Haggling for Rents, Relational Contracts, and the Theory of the Firm

Abstract:

In this paper, a formal rent-seeking theory of the firm is developed. The main idea is that integration (compared to non-integration) facilitates rent-seeking for the integrating party, but makes it harder for the integrated one. In a one-period model, this implies that the rent-seeking contest becomes more uneven and the parties rent-seek less. Here, integration is optimal. In the infinitely-repeated version of the model, it is also possible for the parties to enter a relational contract, under which each promises not to engage in rent-seeking. Such a contract must be self-enforcing, for it cannot be enforced by court. It is shown that integration makes the relational contract less easily sustainable, as, due to its cost advantage, the integrating party gains more from deviating than any party under non-integration. Hence, integration is preferred, if relational contracts are not sustainable, while, otherwise, non-integration may well be preferred. Moreover, it is shown that the model’s predictions are in line with many empirical facts on the choice of ownership structures.

On the "Adverse Selection" of Organizations

Abstract:

According to New Institutional Economics, two or more individuals will found an organization, if it leads to a benefit compared to market allocation. A natural consequence will then be internal rent seeking. We discuss the interrelation between profits, rent seeking and the foundation of organizations. Typically, we expect that highly profitable firms are always founded but it is not clear whether the same is true for firms with less optimistic prospects. We will show that internal rent seeking may lead to a completely reversed result. The impact of internal rent seeking on overall investment and the implications of firm size and competition on the foundation of organizations are also addressed.

Firm Size, Economic Situation and Influence Activities

Abstract:

This paper discusses the optimal firm size in the presence of influence activities, and the level of individual rent-seeking dependent on the economic situation of the firm. Since firm size has a discouraging effect on the level of individual rent-seeking but also a quantity effect as the number of rent-seekers increases, the interplay of both effects determines whether the employer chooses an inefficiently small or large firm size. In the given setting, a bad economic situation leads to both a higher probability of a substantial loss and a reduction of productivity. The productivity effect and the two other effects together determine the optimal level of individual rent-seeking.

Informative Voting and the Samuelson Rule

Abstract:

We study the classical free-rider problem in public goods provision in a large economy with uncertainty about the average valuation of the public good. Individual preferences over public goods are shaped by a skill and a taste parameter. We use a mechanism design approach to solve for the optimal utilitarian provision rule. The relevant incentive constraints for information aggregation ensure that individuals behave as if they were engaging in informative voting over the level of public good provision. It is shown that the use of information by an optimal provision rule is inversely related to the polarization of preferences which results from the properties of the skill distribution.

Market Discipline, Information Processing, and Corporate Governance

Abstract:

The paper reviews and assesses our understanding of the notion of “market discipline” in corporate governance. It questions the wholesale appeal to this notion in policy discussion, which fails to provide an account of the underlying mechanisms in terms of theory and empirical analysis. Discipline that is provided by the “market” must be compared to discipline that is provided by other institutions, e.g., intermediaries acting as “delegated monitors”. The comparative assessment depends on (i) the information technology, (ii) the role of strategic interactions, and (iii) the disciplinary mechanism itself. Concerning (i), the question is whether the benefits of multiple sources of information exceed the costs. Concerning (ii), strategic interactions concern the free-rider problem in acquiring information that benefits all financiers, as well as distributive externalities involved in exploiting an information advantage to the detriment of other financiers. Concerning (iii), the question is whether investors have explicit intervention rights or whether “discipline” results from managerial acquiescence. As for the acquisition and aggregation of information in organized markets, positive welfare effects arise only if the information is put to productive use, either through improvements in real investment and managerial incentives, or through changes in corporate control. Necessary conditions for such benefits to arise are fairly restrictive, especially if the changes that occur are based on managerial acquiescence rather than the legal intervention rights of investors. The expansion of market-based managerial incentives in the nineties had little to do with these theoretical accounts. The experience of moral hazard that has accompanied this expansion, on the side of gate-keeping institutions as well as corporate management, confirms the predictions of theory about the potential for shortfalls in market discipline and the agency costs of equity finance through the open market.

Migration and the Welfare State: The Economic Power of the Non-Voter?

Abstract:

This paper investigates the impact of emigration on the political choice regarding the size of the welfare state. Mobility has two countervailing effects: the political participation effect and the tax base effect. With emigration, the composition of the constituency changes. This increases the political influence of the less mobile part of the population. The new political majority has to take into account that emigration reduces tax revenues and thereby affects the feasible set of redistribution policies. The interaction of the two effects has so far not been analyzed in isolation. We find that the direction of the total effect of migration depends on the initial income distribution in the economy. Our results also contribute to the empirical debate on the validity of the median-voter approach for explaining the relation between income inequality and redistribution levels.

Entry of Foreign Banks and their Impact on Host Countries

Abstract:

Foreign bank entry is frequently associated with spillover effects for local banks and increasing competition in the local banking market. We study the impact of these effects on host countries. In particular, we ask how these effects interact and how they depend on the competitive environment of the host banking market. An increasing number of banks is more likely to have positive welfare effects the more competitive the market environment, whereas spillovers are less likely to have positive welfare effects the stronger competition. Hence, competitive effects seem to reinforce each other, while spillovers and competition tend to weaken each other.

The Political Economy of Corruption and the Role of Financial Institutions

Abstract:

In many developing countries, we observe rather high levels of corruption. This is surprising from a political economy perspective, as the majority of people generally suffers from high corruption levels. We explain why citizens do not exert enough political pressure to reduce corruption if financial institutions are missing. Our model is based on the fact that corrupt officials have to pay entry fees to get lucrative positions. The mode of financing this entry fee determines the distribution of the rents from corruption. In a probabilistic voting model, we show that a lack of financial institutions can lead to more corruption as more voters are part of the corrupt system. Thus, the economic system has an effect on political outcomes. Well-functioning financial institutions, in turn, can increase the political support for anti-corruption measures.

Private Provision of a Complementary Public Good

Abstract:

For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment. We study this incentive for investment in OSS. In particular we ask how (1) market entry and (2) public investments in the public good affects the firms' production and profits. Surprisingly, we find that there exist cases where incumbents benefit from market entry. Moreover, we show the counter-intuitive result that public spending does not necessarily lead to a decreasing voluntary private contribution.

Two-Sided Markets with Pecuniary and Participation Externalities

Abstract:

The existing literature on "two-sided markets" addresses participation externalities, but so far it has neglected pecuniary externalities between competing platforms. In this paper we build a model that incorporates both externalities. In our setup differentiated platforms compete in advertising and offer consumers a service free of charge (such as a TV program) that is financed through advertising. We show that advertising can exhibit the properties of a strategic substitute or complement. Surprisingly, there exist cases in which platforms benefit from market entry. Moreover, we show that from a welfare point of view perfect competition is not always desirable.

Umbrella Branding and the Provision of Quality

Abstract:

Consider a two-product firm that decides on the quality of each product. Product quality is unknown to consumers. If the firm sells both products under the same brand name, consumers adjust their beliefs about quality subject to the performance of both products. We show that if the probability that low quality will be detected is in an intermediate range, the firm produces high quality under umbrella branding whereas it would sell low quality in the absence of umbrella branding. Hence, umbrella branding mitigates the moral hazard problem. We also find that umbrella branding survives in asymmetric markets and that even unprofitable products may be used to stabilize the umbrella brand. However, umbrella branding does not necessarily imply high quality; the firm may choose low-quality products with positive probability.

Observable Reputation Trading

Abstract:

Is the reputation of a firm tradable when the change in ownership is observable? We consider a competitive market in which a share of owners must retire in each period. New owners bid for the firms that are for sale. Customers learn the owner’s type, which reflects the quality of the good or service provided, through experience. After observing an ownership change they may want to switch firm. However, in equilibrium, good new owners buy from good old owners and retain high-value customers. Hence reputation is a tradable intangible asset, although ownership change is observable.

When is FDI a Capital Flow?

Abstract:

In this paper we analyze the conditions under which a foreign direct investment (FDI) involves a net capital flow across countries. Frequently, foreign direct investment is financed in the host country without an international capital movement. We develop a model in which the optimal choice of financing an international investment trades off the relative costs and benefits associated with the allocation and effectiveness of control rights resulting from the financing decision. We find that the financing choice is driven by managerial incentive problems and that FDI involves an international capital flow when these problems are not too large. Our results are consistent with data from a survey on German and Austrian investments in Eastern Europe.

Business Groups in Emerging Markets - Financial Control and Sequential Investment

Abstract:

Business groups in emerging markets perform better than unaffiliated firms. One explanation is that business groups substitute some functions of missing institutions, for example, enforcing contracts. We investigate this by setting up a model where firms within the business group are connected to each other by a vertical production structure and an internal capital market. Thus, the business group’s organizational mode and the financial structure allow a self-enforcing contract to be designed. Our model of a business group shows that only sequential investments can solve the ex post moral hazard problem. We also find that firms may prefer not to integrate.

The Effect of Reputation on Selling Prices in Auctions

Abstract:

In economic approaches it is often argued that reputation considerations influence the behavior of individuals or firms and that reputation influences the outcome of markets. Empirical evidence is rare though. In this contribution we argue that a positive reputation of sellers should have an effect on selling prices. Analyzing auctions of popular DVDs at eBay we, indeed, find support for this hypothesis. Secondary, we unmask the myth that it is promising for eBay sellers to let their auction end at the evening, when many potential buyers may be online.

On Delegation under Relational Contracts

Abstract:

In this paper, a principal’s decision between delegating two tasks or handling one of the two tasks herself is analyzed. We assume that the principal uses both, formal contracts and informal agreements sustained by the value of future relationships (relational contracts) as incentive device. It is found that the principal is less likely to delegate both tasks in a dynamic setting than in a static one (where formal contracts are the only feasible incentive device), as handling one task herself enables a much wider use of relational contracts.

Job Promotion Tournaments and Imperfect Recall

Abstract:

In this paper, a promotion tournament is considered, where, at the beginning of the tournament, it is unknown how long the tournament lasts. Further, the promotion decision is based on the assessments of a supervisor with imperfect recall. In line with psychological research, the supervisor is assumed to either value early or recent impressions more strongly. It is shown that effort may increase or decrease, as the probability of promotion in a certain period gets higher. The single effects determining the sign of the effort change oftentimes depend on how the supervisor processes information.

Implicit Contracts: Two Different Approaches

Abstract:

In this paper, I compare two different approaches to model implicit contracting, the infinite-horizon approach typically used in the literature and afinite-horizon approach building on an adverse-selection model. I demonstrate that even the most convincing result of the infinite-horizon approach, namely that implicit contracting is improved, if the discountrate is lowered, does not carry over to the alternative modeling approach. Predictions of the first approach should therefore be handled with care and subject to athorough reinvestigation.

Recent years have witnessed an enormous amount of reorganization of the corporate sector in the US and in Europe. This paper examines the role of market competition for this trend in corporate reorganization. We find that at intermediate levels of competition the CEO of the corporation decides to have less power inside the firm and to delegate control to lower levels of the firms’ hierarchy. Thus, workers empowerment and the move to flatter firm organizations emerge as an equilibrium when competition is not too tough and not too weak. The model predicts merger waves or waves of outsourcing when countries become more integrated into the world economy as the corporate sector reorganizes in response to an increase in international competition.

The Threat of Capital Drain: A Rationale for Public Banks?

Abstract:

This paper yields a rationale for why subsidized public banks may be desirable from a regional perspective in a financially integrated economy. We present a model with credit rationing and heterogeneous regions in which public banks prevent a capital drain from poorer to richer regions by subsidizing local depositors, for example, through a public guarantee. Under some conditions, cooperative banks can perform the same function without any subsidization; however, they may be crowded out by public banks. We also discuss the impact of the political structure on the emergence of public banks in a political-economy setting and the role of interregional mobility.

How Licensing Resolves Hold-Up: Evidence from a Dynamic Panel Data Model with Unobserved Heterogeneity

Abstract:

In a patent thicket licensing provides a mechanism to either avoid or resolve hold-up. Firms' R&D incentives will differ depending on how licensing is used. In this paper we study the choice between ex ante licensing to avoid hold-up and ex post licensing to resolve it. Building on a theoretical model of a patent portfolio race, firms' choices of licensing contracts are modelled. We derive several hypotheses from the model and find support for these using data from the semiconductor industry. The empirical results show that firms' relationships in product markets and technology space jointly determine the type of licensing contract chosen. Implications for the regulation of licensing are discussed. We estimate a dynamic panel data model with unobserved heterogeneity and a lagged dependent variable. A method suggested by Wooldridge (2005) is employed to estimate a random effects probit model using conditional maximum likelihood.

Optimal Ownership Structures in the Presence of Investment Signals

Abstract:

The property-rights approach to the theory of the firm is extended by introducing distorted signals of the parties.investments. Investment incentives are then given in two ways, by allocating ownership rights and by tying pay to the signal realization. Optimal incentive strength, that is, the weight that a signal is optimally given in a wage contract, depends on two distortions, namely the distortion of the signal from the realized and from the disagreement benefit. Under the optimal ownership structure, the deviations of both investments from their first-best levels are relatively small implying that the relative importance of investment matters. Further, it is shown that most of the Grossman-Hart-Moore results are not robust to an introduction of investment signals.

Performance Pay and Risk Aversion

Abstract:

A main prediction of agency theory is the well known risk-incentive trade-off. Incentive contracts should be found in environments with little uncertainty and for agents with low degrees of risk aversion. There is an ongoing debate in the literature about the first trade-off. Due to lack of data, there has so far been hardly any empirical evidence about the second. Making use of a unique representative data set, we find clear evidence that risk aversion has a highly significant and substantial negative impact on the probability that an employee's pay is performance contingent.

Contractual Incentive Provision and Commitment in Rent-Seeking Contests

Abstract:

In this paper, we consider a symmetric rent-seeking contest, where employees lobby for a governmental contract on behalf of firms. The only verifiable information is which firm is assigned the contract. We derive the optimal wage contracts of the employees and analyze, whether commitment by determining the wage contract prior to the competitor is profitable. This is indeed the case, i.e. firms prefer to move first in the wage-setting subgame. This complements previous work on rent-seeking contests emphasizing that commitment via rent-seeking expenditures is unprofitable in symmetric contests.

Should You Allow Your Agent to Become Your Competitor? On Non-Compete Agreements in Employment Contracts

Abstract:

We discuss a principal-agent model in which the principal has the opportunity to include a non-compete agreement in the employment contract. We show that not imposing such an agreement can be beneficial for the principal as the possibility to leave the firm generates implicit incentives for the agent. The principal prefers to impose such a clause if and only if the value created is sufficiently small relative to the agent's outside option. If the principal can use an option con- tract for retaining the agent, she will never prefer a strict non-compete agreement.

Organization of Multinational Activities and Ownership Structure

Abstract:

We develop a model in which multinational investors decide about the modes of organization, the locations of production, and the markets to be served. Foreign investments are driven by market-seeking and cost-reducing motives. We further assume that investors face costs of control that vary among sectors and increase in distance. The results show that (i) production intensive sectors are more likely to operate a foreign business independent of the investment motive, (ii) that distance may have a non-monotonous effect on the likelihood of horizontal investments, and (iii) that globalization, if understood as reducing distance, leads to more integration.

Optimal Income Taxation and Public Good Provision in a Two-Class Economy

Abstract:

This paper combines the problem of optimal income taxation with the free-rider problem in public good provision. There are two groups of individuals with private information on their earning ability and their valuation of a public good. Adjustments of the transfer system are needed to discourage the more productive from exaggerating the desirability of public good provision. Similarly, the less productive need to be prevented from understating their valuation. Relative to an optimal income tax, which focuses solely on earning ability, income transfers are increased whenever a public good is installed and are decreased otherwise.

Foreign Banks in Eastern Europe: Mode of Entry and Effects on Bank Interest Rates

Abstract:

Credit markets in many Eastern European countries are now dominated by foreign-owned banks. We analyze the development for foreign ownership and its impact on lending rate in ten Eastern European countries between 1995 and 2003. Currently, the majority of loans from foreign banks is granted by acquired banks. The presence of foreign acquired banks as measured by their relative number among the banks in our dataset increased somewhat slower than that of foreign de novo banks. However, since market entry through acquisition allows acquiring a credit portfolio and a customer base, acquired banks were able to expand their market share much faster than the foreign de novo banks. Our results also show that the interest rate decreased after foreign bank entry. Moreover, while the reduction in interest rates of domestic banks is more pronounced in the case of foreign entry through a de novo investment, foreign de novo banks charge higher interest rates than foreign acquired banks.

Bank Size and Risk-Taking under Basel II

Abstract:

We analyze the relationship between bank size and risk-taking under the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we show that the introduction of an internal ratings based (IRB) approach improves upon flat capital requirements if the approach is applied uniformly across banks and if the costs of implementation are not too high. However, the banks’ right to choose between the standardized and the IRB approaches under Basel II gives larger banks a competitive advantage and, due to fiercer competition, pushes smaller banks to take higher risks. This may even lead to higher aggregate risk-taking.

Technology Transfer and Spillovers in International Joint Ventures

Abstract:

It is often argued that multinationals are reluctant to transfer technology due to the fear of spillovers. We show that this need not be the case if host country policies like taxation are taken into account. Furthermore, we examine the incentives the multinational and the host country have to engage in an international joint venture. We show why a multinational may agree to enter a joint venture even though this gives rise to spillovers. Surprisingly, we find that a joint venture is sometimes not in the interest of a host country, despite the prospect of spillovers.

An Economic Approach to Article 82 - Report by the European Advisory Group on Competition Policy

Abstract:

This report argues in favour of an economics-based approach to Article 82, in a way similar to the reform of Article 81 and merger control. In particular, we support an effects-based rather than a form-based approach to competition policy. Such an approach focuses on the presence of anti-competitive effects that harm consumers, and is based on the examination of each specific case, based on sound economics and grounded on facts.

A New International Division of Labor in Europe: Outsourcing and Offshoring to Eastern Europe

Abstract:

Europe is reorganizing its international value chain. I document these changes in Europe’s international organization of production with new survey data of Austrian and German firms investing in Eastern Europe. I show estimates of the share of intrafirm trade between Austria or Germany on the one hand and Eastern Europe on the other. Furthermore, I present empirical evidence of the drivers of the new division of labor in Europe. I find among other things that falling trade costs and reduced levels of corruption as well as improvements in the contracting environment in Eastern Europe are affecting the level of intrafirm imports from that region. These factors also favor outsourcing over offshoring. In contrast, low organizational costs of hierarchies and large costs of holdup (when there are no alternative investors in Old Europe or no alternative suppliers in Eastern Europe) favor offshoring over outsourcing. Tax holidays granted by host countries in Eastern Europe also mildly affect the organizational choice.

Financial Crisis, Economic Recovery, and Banking Development in Russia, and other FSU Countries

Abstract:

This paper provides a unified analysis for the onset of the 1998 financial crisis and the strong economic recovery afterward in Russia and other former Soviet Union countries. Before the crisis a banking failure arose owing to the coexistence of a lemons credit market and high government borrowing. In a lemons credit market low credit risk firms switched from bank to nonbank finance, including trade credits and barter trade, generating an externality on banks’ interest rates. The collapse of the treasury bills market in the financial crisis triggered a change in banks’ lending behavior, providing initial conditions for banking development.

Law in Transition and Development: The Case of Russia

Abstract:

The rise of barter and non-cash payments has become a dominant feature of the Russian transition to a market economy. This paper confronts with empirical evidence two approaches to explain barter in Russia: the ’illusion view’ and the ’trust view’ of barter. The ’illusion view’ suggests that barter allows the parties to pretend that the manufacturing sector in Russia is producing value added by enabling this sector to sell its output at a higher price than its market value. The ’trust view’ sees barter as an institution to deal with the absence of trust and liquidity in the Russian economy. We confront the prediction of both explanations with actual data on barter in Ukraine in 1997. The data reject the ’illusion view‘ in favor of the ‘trust view‘ of barter.

‘A Nation of Poets and Thinkers’ - Less So with Eastern Enlargement? Austria and Germany

Abstract:

Many people in the European Union fear that Eastern Enlargement will lead to major job losses. More recently, these fears about job losses have extended to high skill labor and IT jobs. The paper examines with new firm level data whether these fears are justified for the two neighboring countries of Eastern Enlargement Austria and Germany. I find that Eastern Enlargement leads to surprising small job losses, because jobs in Eastern Europe do not compete with jobs in Austria and Germany. Low cost jobs of affiliates in Eastern Europe help Austrian and German firms to stay competitive in an increasingly competitive environment. However, I also find that multinational firms in Austria and Germany are outsourcing the most skill intensive activities to Eastern Europe taking advantage of cheap abundant skilled labor in Eastern Europe. I find that the firms’ outsourcing activities to Eastern Europe are a response to a human capital scarcity in Austria and Germany which has become particularly severe in the 1990s. Corporations’ outsourcing of skill intensive firm activity to Eastern Europe has helped to ease the human capital crisis in both countries. I find that high skilled jobs transferred to Eastern Europe account for 10 percent of Germany’s and 48 percent of Austria’s supply of university graduates in the 1990s. I then discuss what can be done to address the skill exodus to Eastern Europe. I show that R&D subsidies do not work in economies with a skill crisis and I suggest to liberalize the movement of high skill labor with Eastern Enlargement.

Is Human Capital Losing From Outsourcing? Evidence for Austria and Poland

Abstract:

Feenstra and Hanson (1997) have argued in the context of the North American Free Trade Agreement that US outsourcing to Mexico leads to an increase in the skill premium in both the US and Mexico. In this paper we show on the example of Austria and Poland that with the new international division of labor emerging in Europe Austria, the high income country, is specializing in the low skill intensive part of the value chain and Poland, the low income country, is specializing in the high skill part. As a result, skilled workers in Austria are losing from outsourcing, while gaining in Poland. In Austria, relative wages for human capital declined by 2 percent during 1995-2002 and increased by 41 percent during 1994-2002 in Poland. In both countries outsourcing contributes roughly 35 percent to these changes in the relative wages for skilled workers. Furthermore, we show that Austria’s R&D policy has contributed to an increase in the skill premium there.

The Origins of the German Corporation – Finance, Ownership and Control

Abstract:

The ownership of German corporations is quite different today from that of Anglo-American firms. How did this come about? To what extent is it attributable to regulation? A specially constructed data set on financing and ownership of German corporations from the end of the 19th century reveals that, as in the UK, there was a high degree of activity on German stock markets with firms issuing equity in preference to borrowing from banks, and insider and family ownership declining rapidly. However, unlike in the UK, other companies and banks emerged as the main holders of equity, with banks holding shares primarily as custodians of other investors rather than on their own account. The changing pattern of ownership concentration was therefore very different from that of the UK with regulation reinforcing the control that banks exercised on behalf of other investors.

A Note on Sabotage in Collective Tournaments

Abstract:

In this paper a tournament between teams (a collective tournament) is analyzed, where each contestant may spend productive effort in order to increase his team's performance or sabotage the members of the opponent team. It is shown that sabotaging the weaker members of a team always decreases their team's performance more significantly than sabotaging stronger members does. As a consequence, sabotage activities are only directed at a team's weaker members. This finding is quite interesting, as previous results on individual tournaments indicate that oftentimes only the stronger participants should be sabotaged.

Rent seeking in sequential group contests

Abstract:

In this paper, a group contest is analyzed, where the groups are allowed to determine their sharing rules either sequentially or simultaneously. It is found that in case the more numerous group determines its sharing rule prior to the smaller group, rent dissipation in the group contest is higher than in an individual contest. However, if the order of moves is endogenized, the smaller group will always act prior to the bigger group. Competition between the groups is in this way weakened and the groups are able to save on expenditures.

Doping in Contest-Like Situations

Abstract:

Individuals who compete in a contest-like situation (for example, in sports, in promotion tournaments, or in an appointment contest) may have an incentive to illegally utilize resources in order to improve their relative positions. We analyze such doping within a tournament game between two heterogeneous players. Three major effects are identified which determine a player’s doping decision — a cost effect, a likelihood effect and a windfall-profit effect. Moreover, we discuss whether the favorite or the underdog is more likely to be doped, the impact of doping on overall performance, the influence of increased heterogeneity on doping, the welfare implications of doping, and possible prevention of doping.

Emotions and the Optimality of Unfair Tournaments

Abstract:

We introduce a concept of emotions that emerge when workers compare their own performance with the performances of co-workers. Assuming heterogeneity among the workers the interplay of emotions and incentives is analyzed within the framework of rank-order tournaments which are frequently used in practice. Tournaments seem to be an appropriate starting point for this concept because the main idea of a tournament is inducing incentives by making workers compare themselves with their opponents. We differentiate between exogenous and endogenous tournament prizes and identify certain conditions under which the employer benefits from emotional workers. In this case, he clearly prefers unfair to fair tournaments. Furthermore, the concept of emotions is used to explain the puzzling findings on the oversupply of effort in experimental tournaments.

Integrating competition policy and innovation policy: the case of R&D cooperation

Abstract:

I develop a model of R&D cooperation with uncertain research outcomes. In this model asymmetric outcomes of R&D competition emerge naturally. Therefore ex-ante and ex-post R&D cooperation can be studied as alternatives for firms. Using this model I compare welfare losses under ex-ante and ex-post R&D cooperation as the degree of product market competition varies. It emerges that the relative size of these welfare losses is monotonically related to the degree of product market competition and the degree of technological opportunity. The implications of these results for the interaction of competition policy and innovation policy are discussed.

Spillovers Reconsidered: Analysing Economic Welfare under complementarities in R&D

Abstract:

We analyse economic welfare in R&D intensive industries under varying assumptions on the spillover process. The focus lies on spillover processes with complementary R&D investments such as those modelling absorptive capacity. There spillovers give rise to both negative and positive externalities. We show that the rationale for public policy intervention is strengthened where spillovers also have positive effects. This conclusion is based on the supermodularity of the spillover process and the investment game. We characterise a large class of spillover processes with similar implications for public policy. We show that results of much empirical work on absorptive capacity extend to this class of models.

Tournaments versus Piece Rates under Limited Liability

Abstract:

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004

The existing literature on the comparison of tournaments and piece rates as alternative incentive schemes has focused on the case of unlimited liability. However, in practice real workers’ wealth is typically restricted. Therefore, this paper compares both schemes under the assumption of limited liability. The results show that if the cost function is sufficiently convex, first-best effort will be more likely implemented under piece rates than under tournaments. Moreover, if first-best implementation is not achieved and workers earn positive rents, efforts and profits will be larger for piece rates than for tournaments given sufficiently convex costs. While tournaments offer a partial insurance due to their fixed prizes, piece rates may not work any longer if potential losses become prohibitively high. Finally, if risk is sufficiently high, piece rates will dominate tournaments despite the partial insurance effect of tournament compensation. Since effort costs and risk may depend on an individual worker’s characteristics, on the characteristics of his job and on his hierarchical position, these findings have important implications for the choice of incentive schemes and the allocation of workers in firms.

Does Partnering Pay Off? - Stock Market Reactions to Inter-Firm Collaboration Announcements in Germany

Abstract:

The dramatic increase in interorganizational partnering in the last two decades raises questions for scholars and managers regarding the value impact of inter-firm collaborations. Using event study methodology, this paper tests whether stock market reactions differ when a collaboration formation or termination is announced. In addition, the study provides an in-depth analysis of potential determinants of stock market reactions to collaboration formation announcements. The sample consists of 1037 announcements in German stock markets from 1997 to 2002. The results show that an unexpected termination announcement decreases firm valuation, and a formation announcement increases firm valuation. Further, certain collaborations are more favorable than others, depending on firm industry, age, size, collaboration constellations, and equity versus non-equity investment in partner firm. The results open avenues for further research on partnering strategies.

Banks without Parachutes - Competitive Effects of Government Bail-out Policies

Abstract:

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004

The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the banking sector. Our main result is that the bail-out policy unambiguously leads to higher risk-taking at those banks that do not enjoy a bail-out guarantee. The reason is that the prospect of a bail-out induces the rotected bank to expand, thereby intensifying competition in the deposit market and depressing other banks’ margins. In contrast, the effects on the protected bank’s risk taking and on welfare depend on the transparency of the banking sector.

Globalization and the Empowerment of Talent

Abstract:

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004

Globalization has been identified by many experts as a new way firms organize their activities and as the emergence of talent as the new stakeholder in the firm. This paper examines the role of trade integration for the changing nature of the corporation. International trade leads to a ’war for talent’ which makes it more likely that an organizational equilibrium emerges in the integrated world economy in which control is delegated to lower levels of the firms’ hierarchy empowering human capital. Furthermore, trade integration is shown to lead to waves of outsourcing and to convergence in corporate cultures across countries.
