The standard contest model in which participants compete in a single dimension is well understood and documented. Multi-dimension extensions are possible but are liable to increase the complexity of the contest structure, mitigating one of its main advantages: simplicity. In this paper we propose an extension in which competition ensues in several dimensions and a competitor that wins a certain number of these is awarded a prize. The amount of information needed to run the contest is hence limited to the number of dimensions won by each player. We look at the design of this contest from the point of view of maximizing effort in the contest (per dimension and totally), and show that there will be a tendency to run small contests with few dimensions. The standard Tullock model and its results are encompassed by our framework.

We set up a simple political economy model where economic integration raises the profitability of multinational firms. In this setting redistributive taxation may rise following economic integration, if the effects of the widened income gap dominate the higher excess burden of the tax.

While most market transactions are subject to strong incentives, transactions within firms are often not incentivized. We offer an explanation for this observation based on envy among agents in an otherwise standard moral hazard model with multiple agents. Envious agents suffer if other agents receive a higher wage due to random shocks to their performance measures. The necessary compensation for expected envy renders incentive provision more expensive, which generates a tendency towards flat-wage contracts. Moreover, empirical evidence suggests that social comparisons like envy are more pronounced among employees within firms than among individuals who interact only in the market. Flat-wage contracts are thus more likely to be optimal in firms than in markets.

For the estimation of many econometric models, integrals without analytical solutions have to be evaluated. Examples include limited dependent variables and nonlinear panel data models. In the case of one-dimensional integrals, Gaussian quadrature is known to work efficiently for a large class of problems. In higher dimensions, similar approaches discussed in the literature are either very specific and hard to implement or suffer from exponentially rising computational costs in the number of dimensions - a problem known as the "curse of dimensionality" of numerical integration. We propose a strategy that shares the advantages of Gaussian quadrature methods, is very general and easily implemented, and does not suffer from the curse of dimensionality. Monte Carlo experiments for the random parameters logit model indicate the superior performance of the proposed method over simulation techniques.

There is strong evidence that in bargaining situations with asymmetric outside options people exhibit self-serving biases concerning their fairness judgements. Moreover, psychological literature suggests that this can be a driving force of bargaining impasse. This paper extends the notion of inequity aversion to incorporate self-serving biases due to asymmetric outside options and analyses whether this leads to bargaining breakdown. I distinguish between sophisticated and naive agents, that is, those agents who understand their bias and those who do not. I find that breakdown in ultimatum bargaining results from naiveté of the proposers.

This paper analyses the role of ratification quotas in multilateral agreements over emission reduction. The higher is the quota, the lower is the level of emissions in case the agreement comes into force, but the higher is also the risk of failure. In a setting with incomplete information, two country types and a binary contribution to the provision, I examine the differences between simultaneous and sequential ratification. When the benefits from emission of both types are smaller than the social costs, the outcome in the simultaneous case is essentially identical to the sequential case. The optimal quota is 100% and achieves the first best. With the high type's benefits exceeding the social costs, I find that the optimal quota is as small as possible, if ratification is simultaneous. In the sequential ratification case, I cannot determine the optimal quota. However, I find that the aggregate expected surplus decreases with respect to the simultaneous case.

This paper reviews the recent theoretical literature that analyses the European Union's policy to eliminate preferential corporate tax regimes and the proposal to introduce a consolidated EU tax base with formula apportionment for the taxation of multinational firms. Since neither proposal includes a harmonisation of corporate tax rates, a core issue is how tax competition between member states will be affected by these partial coordination measures. The conclusions from our review are supportive of the EU's ban on preferential tax regimes, but the economic incentive effects of a switch to formula apportionment are found to be ambiguous.

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum likelihood estimator and a moments estimator that builds on the idea that some moments are equalized to their expectations. These estimators perform quite similar in many cases. In some cases, however, the moments estimator is preferable both to the proposed likelihood estimator and the Kalman filter, as implemented in the program package Eviews.

When a young entrepreneurial firm matures, it is often necessary to replace the founding entrepreneur by a professional manager. This replacement decision can be affected by the private benefits of control enjoyed by the entrepreneur which gives rise to a conflict of interest between the entrepreneur and the venture capitalist. We show that a combination of convertible securities and contingent control rights can be used to resolve this conflict efficiently. This contractual arrangement is frequently observed in venture capital finance.

We study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests. Players may win a prize for winning each component contest, as well as a prize for winning the overall race. Each component contest is an all-pay auction with complete information. We characterize the unique equilibrium analytically and demonstrate that it exhibits endogenous uncertainty. Even a large lead by one player does not fully discourage the other player, and each feasible state is reached with positive probability in equilibrium (pervasiveness). Total effort may exceed the value of the prize by a factor that is proportional to the maximum number of stages. Important applications are to war, sports, and R&D contests and the results have empirical counterparts there.

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.

This paper analyses the development of the ratio of corporate taxes to wage taxes using a simple political economy model with internationally mobile and immobile firms. Among other results, our model predicts that countries reduce their corporate tax rate, relative to the wage tax, either when preferences for public goods increase or when a rising share of capital is employed in multinational firms. The predicted relationships are tested using panel data for 23 OECD countries for the period 1980 through 2001. The results of the empirical analysis support our central hypotheses.

This note critically evaluates the New Classical Macroeconomics from a Marshallian perspective. Revisiting the famous Keynes-Tinbergen controversy, it is argued that Keynes' criticism comprises the "Lucas critique," and that it is misleading to label this a critique of Keynesian economics. The postulate of immutable economic structures carries Tinbergen's approach to the extreme and neglects the possibility of slowly changing structures, as conceived by Marshall. The position is defended by arguments about equilibrium and rationality that are admittedly empty.

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.

Uzawa (1961) has shown that balanced growth requires technological progress to be strictly Harrod neutral (purely labor-augmenting). This paper offers a slightly more general variant of the theorem that does not require assumptions about savings behavior or factor pricing and is much easier to prove.

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.

The industrialization process of a country is often plagued by a failure to coordinate investment decisions. Using the Global Games approach we can solve this coordination problem and eliminate the problem of multiple equilibria. We show how appropriate information provision enhances efficiency. We discuss extensions of the model and argue that subsidies may be a property of a signalling equilibrium to overcome credibility problems in information provision. In addition we point out possible problems with overreaction to public information. Furthermore, we suggest a new focus for development policy.

This paper explores to what extent secondary policy issues are infuenced by electoral incentives. We develop a two dimensional political agency model in which a politician decides on both a frontline policy issue and a secondary policy issue. The model predicts when the incumbent should manipulate the secondary policy to attract voters. We test our model by using panel data on environmental policy choices in the U.S. states. In contrast to the popular view that secondary policies are largely determined by lobbying, we find strong effects of electoral incentives.

We formulate a model to explain why the lack of political competition may stifle economic performance and use the United States as a testing ground for the model’s predictions, exploiting the 1965 Voting Rights Act which helped break the near monpoly on political power of the Democrats in southern states. We find statistically robust evidence that changes in political competition have quantitatively important effects on state income growth, state policies, and quality of Governors. By our bottom-line estimate, the increase in political competition triggered by the Voting Rights Act raised long-run per capita income in the average affected state by about 20 percent.

The hallmark of the recent development and growth literature is a quest to identify institutions that explain a significant portion of the observed differences in living standards across countries. Empirical work in the area focuses almost exclusively on either the global sample or on developing nations. Certainly it is important to know which institutions are lacking in these developing countries, but the analysis provides little evidence for us to know to what extend a common set of institutions actually matters in advanced and developing countries. In this paper we examine parameter heterogeneity in prominent approaches to institutions and economic performance. We find that a new set of instruments is necessary to control for endogeneity, but that a common set of economically important institutions does indeed exist among advanced and developing nations. The impact of these institutions does vary substantially across samples; it is about three times as high in developing countries as compared to OECD countries.

The article advances the hypothesis that Germany is unable to increase its gains from trade despite increasing trading volumes. High and rigid German wages argely result from the minimum wage constraint imposed by a welfare state that offers generous replacement incomes. Confronted by low-wage competition from post-communist countries, Germany overspecializes in capital intensive goods, which creates a pathological export boom in terms of added value produced in exports. In addition, the country overspecializes in downstream activities, which implies that export quantities grow faster than value added. The reasons which induce extremely high exports are the same as those which cause unemployment to rise and the economy to stagnate.

Using simple benchmark models, this paper gives an introductory analysis of three separate policy issues that relate to the taxation of multinational firms: (i) the spread of tax measures that provide discriminatory tax relief to multinational firms; (ii) the switch from the current separate accounting system to a consolidated corporate tax base with formula apportionment; (iii) the introduction of a minimum statutory corporate tax rate in a geographically restricted area. Prior to these analyses, we briefly survey some of the empirical evidence on both the general development of corporate taxation in Europe and the OECD, and on the tax preferences granted to multinational firms.

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 e¤ects has so far not been analyzed in isolation. We find that the direction of the total e¤ect 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.

We analyze a sequential game between two symmetric countries when firms can invest in a multinational structure that confers tax savings. Governments are able to commit to long-run tax discrimination policies before firms' decisions are made and before statutory capital tax rates are chosen non-cooperatively. Whether a coordinated reduction in the tax preferences granted to mobile firms is beneficial or harmful for the competing countries depends critically on the elasticity with which the firms' organizational structure responds to tax discrimination incentives. The model can be applied to recent policy initiatives that aim at a ban on preferential tax regimes and at reducing the profit shifting opportunities for multinational firms.

In many countries, governments involve interest groups at early stages of political decisionmaking. The idea of this is to enhance the legitimacy of the policy decision and to curb later opposition to the implementation of the policy. We show that the way and timing of interest groups involvement can be crucial for the scope and success of policy reforms. When interest groups influence both the policy choice, or legislation, and the subsequent decision on the implementation of the policy, their early involvement may lead them to oppose the reform more than if they had been excluded from the legislation stage.

We show experimentally that fairness concerns may have a decisive impact on the actual and optimal choice of contracts in a moral hazard context. Bonus contracts that offer a voluntary and unenforceable bonus for satisfactory performance provide powerful incentives and are superior to explicit incentive contracts when there are some fair-minded players. But trust contracts that pay a generous wage upfront are less efficient than incentive contracts. The principals understand this and predominantly choose the bonus contracts. Our results are consistent with recently developed theories of fairness, which offer important new insights into the interaction of contract choices, fairness and incentives.

The paper reports the principal findings of a long term research project on the description and explanation of business cycles. The research strongly confirmed the older view that business cycles have large systematic components that take the form of investment cycles. These quasi-periodic movements can be represented as low order, stochastic, dynamic processes with complex eigenvalues. Specifically, there is a fixed investment cycle of about 8 years and an inventory cycle of about 4 years. Maximum entropy spectral analysis was employed for the description of the cycles and continuous time econometrics for the explanatory models. The central explanatory mechanism is the second order accelerator, which incorporates adjustment costs both in relation to the capital stock and the rate of investment. By means of parametric resonance it was possible to show, both theoretically and empirically how cycles aggregate from the micro to the macro level. The same mathematical tool was also used to explain the international convergence of cycles. I argue that the theory of investment cycles was abandoned for ideological, not for evidential reasons. Methodological issues are also discussed.

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.

This paper deals with the phenomenon of risk-selection and its appearance in the german compulsory health insurance market since the adoption of the so-called "Gesundheitsstrukturgesetz" of 1992. Further, the "Risikostrukturausgleich" as well as other measures are discussed as instruments of artificially spreading risks in this very market before recommendations for adequate policies are given.

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.

The German apprenticeship system is often considered a role model for vocational education. Its influence on economic growth and technological progress through the provision of human capital to the workforce is widely acknowledged. But recent declines in the number of apprenticeships have led to increasing unrest among policy makers. To counter this development, the government is considering to introduce a training levy scheme that collects training levies from non-training firms in order to subsidize apprenticeship training ("Ausbildungsplatzabgabe"). Such training levy schemes already exist in several industrialized countries and even in some sectors in Germany. Yet, economists differ greatly in opinion about this policy. More surprisingly, however, a general economic analysis of this policy instrument is still lacking. Recent contributions have relied on rather qualitative and partial analyses. This paper aims at closing this gap. Following the training literature, we use a simple oligopsonistic labor market model. Such a setting allows to explain why firms provide and (at least partially) finance general vocational training. Moreover, it can demonstrate that a positive externality arises as other firms benefit from vocational training through poaching. In principle, the Pigouvian prescription of a subsidy scheme financed by a non-distortionary tax could restore the social optimum. The proposed training levy scheme, by contrast, is a particular scheme that links subsidies and levies. This paper unveils that it basically corresponds to a uniform subsidy on apprenticeship training that is financed by a distortionary tax on labor. We show that introducing such a levy scheme can entail ambiguous repercussions on general welfare.

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 intra-firm trade between Austria and 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 falling corruption levels as well as improvements in the contracting environment in Eastern Europe are affecting the level of intra-firm imports from Eastern Europe. They are also favoring outsourcing over offshoring. Low organizational costs of hierarchies and large costs of hold-up (when there are no alternative investors in Old Europe or no alternative suppliers in Eastern Europe) are favoring offshoring over outsourcing. Tax holidays granted by host countries in Eastern Europe also mildly affect the organizational choice.

We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies enacted by a national merger authority tend to be overly restrictive from a global efficiency perspective. In contrast, all international mergers that benefit the merging firms will be cleared by either a national or a regional regulator, and this laissez-faire approach is also globally efficient. Finally, we derive the properties of the endogenous merger equilibrium.

This paper considers a firm whose potential employees have private information on both their productivity and the extent of their fairness concerns. Fairness is modelled as inequity aversion, where fair-minded workers suffer if their colleagues get more income net of production costs. Screening workers with equal productivity but different fairness concerns is shown to be impossible if both types are to be employed, thereby rendering the optimal employment contracts discontinuous in the fraction of fair-minded workers. As a result, fairness might infuence the employment contracts of all workers although only some are fair-minded, and identical firms facing very similar pools of workers might employ very different remuneration schemes.

We report on several experiments on the optimal allocation of ownership rights. The experiments confirm the property rights approach by showing that the ownership structure affects relationship-specific investments and that subjects attain the most efficient ownership allocation despite starting from different initial conditions. However, in contrast to the property rights approach, the most efficient ownership structure is joint ownership. These results are neither consistent with the self-interest model nor with models that assume that all people behave fairly, but they can be explained by the theory of inequity aversion that focuses on the interaction between selfish and fair players.

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.

Recent econometric evidence has noticeably changed views on the desirability and the appropriate design of explicit Deposit Insurance Schemes (DIS). The purpose of this paper is to take a second look at the data. After surveying recent empirical work and providing a theoretical framework, we argue that existing studies may suffer from a selection bias. Building on a new database on explicit deposit insurance compiled by the author, we perform a variety of semi-parametric and parametric tests to see whether and how explicit deposit insurance (de)stabilizes banking systems. We find that the evidence indeed suggests that a selection bias is present. Controlling for this bias leads to a reassessment of recent studies. In particular, making deposit insurance explicit has a rather moderate and, if any, stabilizing effect on the probability of experiencing a systemic crisis.

This paper surveys recent experimental and field evidence on the impact of concerns for fairness, reciprocity and altruism on economic decision making. It also reviews some new theoretical attempts to model the observed behavior.

We argue that with interdependent utility functions growth can lead to a decline in total welfare of a society if the gains from growth are sufficiently unequally distributed in the presence of negative externalities, i.e., envy.

This note comments briefly on Mehdad Vahabi's article on Alfred Marshall's concept of "Normal Value." It points out, in particular, the relationship between normality and equilibrium in the context of Marshall's moving equilibrium method.

Utilitarian voting (UV) is defined in this paper as any voting rule that allows the voter to rank all of the alternatives by means of the scores permitted under a given voting scale. Specific UV rules that have been proposed are approval voting, allowing the scores 0, 1; range voting, allowing all numbers in an interval as scores; evaluative voting, allowing the scores -1, 0, 1. The paper deals extensively with Arrow’s impossibility theorem that has been interpreted as precluding a satisfactory voting mechanism. I challenge the relevance of the ordinal framework in which that theorem is expressed and argue that instead utilitarian, i.e. cardinal social choice theory is relevant for voting. I show that justifications of both utilitarian social choice and of majority rule can be modified to derive UV. The most elementary derivation of UV is based on the view that no justification exists for restricting voters’ freedom to rank the alternatives on a given scale.

This paper discusses how an industrialized country could defend the wages and social benefits of its unskilled workers against wage competition from immigrants. It shows that fixing social standards harms the workers and that fixing social replacement incomes implies migration into unemployment. Defending wages with replacement incomes brings about first-order efficiency losses that outweigh the budget cost to the government. By contrast, wage subsidies involve much smaller welfare losses. While the exclusion of migrants from a national replacement program does not improve the situation, the (temporary) exclusion of migrants from a national subsidy program makes it possible to avoid a distortion of the migration pattern.
