Since the famous Bosman ruling by the European Court of Justice in 1995 transfer fees for football players after moving to another club have become suspect as they are considered as an obstacle to the free movement of workers. However, in an unrestricted market free migration from football...

This paper studies the optimal non linear income tax of couples. We build a general unitary model of labor supply and allow multidimensional heterogeneity in a discrete type framework. We concentrate our analysis on the resulting intra-family labor allocation of labor supplies and show that this...

In this article, we analyse the interactions between financial and start-up decisions in an oligopolistic framework, where firms compete to enter a new market. We show that preemption can substantially reduce the negative effects of credit rationing on start-up investment decisions.

This paper aims at better understanding the inefficiency due to distributional conflicts, which are inherent in every market economy. To this end, we set up a simple general equilibrium model with the following characteristics: two groups of agents (capitalists and workers), an endogenous income...

Recent empirical work shows that judicial dependence can explain high levels of corruption. This paper examines how the dependence of judiciaries influences corruption at different levels of the government in a model where the central government, low-level officials, and the judiciary are...

Two types of agents interact on a pre-existing free platform. Agents value positively the presence of agents of the other type but may value negatively the presence of agents of their own type. We ask whether a new platform can find fees and subsidies so as to divert agents from the existing...

We study competition among market designers who create new trading platforms, when boundedly rational traders learn to select among them. We ask whether efficient platforms, leading to market - clearing trading outcomes, will dominate the market in the long run. If several market designers are...

With endogenous skills and given technology, labor market integration necessarily lowers welfare of the left-behind in a poor sending country, even if all agents face identical emigration probabilities. This is in sharp contrast to the case of exogenous skill supply.

This paper argues that politicians are overprotected. The costs of political assassination differ systematically depending on whether a private or a public point of view is taken. A politician attributes a very high (if not infinite) cost to his or her survival. The social cost of political...

For mitigating the problems of transfer pricing formula apportionment (FA) is discussed intensively. However, FA could even be more harmful than transfer pricing because income shifting would require changing economic decisions instead of just taking advantage of accounting options. We analyze...
