This paper studies the evolution of both characteristics of reciprocity - the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within separated groups. This holds even with randomly formed groups and even when individual preferences are unobservable. Secondly, preferences for rewarding survive only in coexistence with self-interested preferences. But preferences for punishing tend either to vanish or to dominate the population entirely. Finally, the evolution of preferences for rewarding and the evolution of preferences for punishing influence each other decisively. The existence of rewarders enhances the evolutionary success of punishers, but punishers crowd out rewarders.

The estimation of models with time-varying coefficients is usually performed by Kalman-Bucy filtering. The two-sided filter proposed by Schlicht (1988) is statistically and computationally superior to the one-sided Kalman-Bucy filter. This paper describes the estimation procedure and the program package that implements the two-sided filter.

In this paper the term 'globalisation' means the international integration of nationally organised markets in conjunction with increasing cross-country flows of factors of production. According to this globalisation has been under way for centuries. Globalisation is not a completely autonomous, not even a solely market driven process. Historically, it is for the most part determined by decisions of nation states. In times of globalisation speeding up, typically social and political debates start about the driving forces, extent and impact of globalisation. Already two centuries ago, globalisation has been discussed in a similar way as today. Initially, there is a debate about the organisation of the foreign trade regime. Because change of social and economic structures is an integral part of globalisation, the debate about the impact of structural change is constituent in globalisation discourses. Winners and losers of the structural change try to improve their social position through foreign trade policy. These two levels of globalisation discourses are usually distorted by the argument that globalisation and the induced change of societal structures provoke adverse effects on the prevailing system of values. Because of this the globalisation discourse becomes a matter of emotion and disproportionately complex. The paper demonstrates the three levels of a typical globalisation discourse by using three examples. First, the actual globalisation discourse will be discussed. Second, in Germany at the beginning of the 20th century globalisation has been hotly debated under the heading "agrarian versus industrial state". Third, the typical globalisation discourse can also be outlined by the dispute about the reform policy in Prussia in the early 19th century.

This study applies stochastic frontier analytic techniques in the estimation of sporting production functions. As ex ante input factors, we use pre-seasonal estimates of wage bills of players and coaches that are transformed during the production process of a season into ex post pecuniary revenues and sporting success. While in the case of athletic output we find a robust pattern of technical efficiency over subsequent seasons, the estimates based on economic output highlight the instability of the German soccer industry.

The forces of the market and systems competition bring about economic and social convergence in Europe, and there is no need for social policies at the EU level. Social harmonization would distort migration flows and slow down the speed of economic convergence. National welfare states will be threatened by the free migration of people in Europe. The race to the bottom is a serious risk. However, to contain this risk, neither harmonization of welfare payments nor constraints on migration are needed. The adoption of the principle of selectively delayed integration is a better alternative.

This paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a payoff only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use stationary Markovian strategies with posterior beliefs as the state variable. After characterizing the unique symmetric Markovian equilibrium of the game, which is in mixed strategies, we construct a variety of pure-strategy equilibria. There is no equilibrium where all players use simple cut-off strategies. Equilibria where players switch finitely often between the roles of experimenter and free-rider all lead to the same pattern of information acquisition; the efficiency of these equilibria depends on the way players share the burden of experimentation among them. In equilibria where players switch roles infinitely often, they can acquire an approximately efficient amount of information, but the rate at which it is acquired still remains inefficient; moreover, the expected payoff of an experimenter exhibits the novel feature that it rises as players become more pessimistic. Finally, over the range of beliefs where players use both arms a positive fraction of the time, the symmetric equilibrium is dominated by any asymmetric one in terms of aggregate payoffs.

At the Millennium Summit, the world community pledged to promote gender equality and chose as a specific target the achievement of gender equity in primary and secondary education by the year 2005 in every country of the world. Based on the findings from a growing empirical literature that suggests that gender equity in education promotes economic growth and reduce fertility, child mortality, and undernutrition, we estimate what the costs in terms of growth, and forgone fertility, mortality and undernutrition reduction, will be for the 45 countries that are, on current projections, unlikely to meet the target. Our estimates suggest that, by 2005, the countries that are off track are likely to suffer 0.1-0.3 percentage points lower per capita growth rates as a result and will have 0.1-0.4 more children per woman, and, by 2015, an average of 14 per 1000 higher rates of under five mortality and 2.4 percentage points higher prevalence of underweight children under five. Sensitivity analyses suggest that the results are quite robust to using different specifications and approaches to estimating these losses.

The theory of tax competition suggests that different tools might be used to attract physical capital and taxable profits. While it is assumed that FDI in real activity is deterred by high effective taxes, investment undertaken for purpose of profit-shifting is deterred by a higher statutory tax rate. Using information from the RWI-Database "Globalisation", which contains statistics about foreign engagements of the most important German enterprises, this paper investigates if this assumption holds in reality. Differentiating between the functional form of engagement and using a linear regression, the analysis provides evidence that FDI in real activity (production) is correlated with effective tax rates while FDI that implies more opportunities for profit shifting activities (service, finance and R&D) is correlated with the tatutory tax rate.

We develop a dynamic stochastic equilibrium model of two locations within a city where heterogeneous households make joint location and tenure mode decisions. To investigate the effect of homeownership on equilibrium prices and allocations, we compare the response of this model economy to a labor shock with that of a rental-only version. This comparison yields three results. First, homeownership enables more households to remain in the more desirable location at the expense of newcomers. Second, homeownership adds to the volatility of the housing market. Third, homeownership may amplify the dispersion of household income within a location. Homeownership raises distributional issues. The households who consume the most housing gain the most from the ability to own their home. Newcomers to the city are the main losers.

This paper provides a unified theory to explain the onset of the financial crisis in 1998 and the striking economic recovery in Russia and the former Soviet Union afterwards. Before the crisis, the banking sector in these economies was stuck in a development trap in which the banking sector is separated from the real sector of the economy. The separation between the two sectors arises due to a lemons lending market and due to a large government budget. In a lemons credit market firms may find it cheaper to raise liquidity through non-bank finance (trade credits from other firms) rather than through bank finance. As a result non-bank finance may generate an externality on the lending rates of banks. In equilibrium most firms in the economy rely on non-bank finance and the financial sector focuses on trading government securities. The collapse of the treasury bills market in Russia in the financial crisis of 1998 reversed this process and thus acted as a trigger to pull the economy out of the trap. This has led to the strong economic recovery and provided initial conditions for banking development. Empirical evidence with firm level data from Ukraine in 1997 and with country level data for transition economies support the model’s predictions.

This paper studies the effect of technology spillovers on the entry decision of a multinational enterprise into a foreign market. Two alternative entry modes for a foreign direct investment are considered: Greenfield investment versus acquisition. We find that with quantity competition a spillover makes acquisitions less attractive, while with price competition acquisitions become more attractive. Asymmetric information about potential spillovers always reduces the number of acquisitions independently of whether the host country or the entrant has private information. Interestingly, we find that asymmetric information always hurts the entrant, while it sometimes is in favor of the host country.

Globalization has been identified by many experts as a new way firms organize their activities and as the emergence of human capital as the new stakeholder of the firm. This paper surveys recent work which examines the role of trade integration for these changes in corporate organization. More intense competition and the change in the pattern of specialization following trade liberalization make it both more likely that an organizational equilibrium emerges in which power is delegated to lower levels of the firms' hierarchy empowering human capital. Furthermore, trade integration leads to waves of outsourcing and to a convergence in corporate cultures across countries.

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 paper takes a first look at the host and home country effects of German FDI in Eastern Europe (EE) based on new survey data of 1050 investment projects in EE by 420 German multinationals during the 1990s. We find that German investors transfer a substantial amount of financial capital to EE. Furthermore, the most dynamic and innovative segment of the German economy invests in the East which explains why single owned firms dominate as the form of control. We also find strong evidence of vertical FDI suggesting that German cororations are outsourcing a substantial share of their production to EE affiliates to exploit lower wages in the East.
