Although collusive tax evasion by buyers and sellers of commodities and also by employers and employees is widespread all over the world, it has rarely been analyzed in the tax evasion literature. To fill this gap and to compare collusive tax evasion with independent tax evasion, this paper...

The third generation UMTS auction in Germany raised an enormous amount of revenue, and at the same time achieved a more competitive market structure than other UMTS auctions in Europe. The present paper explains the design of that auction, and presents a game theoretic explanation of observed...

The second-generation GSM spectrum auction in Germany is probably the most clear cut example of a low price outcome in a simultaneous ascending-bid auction.The present paper gives an account of the events, describes the auction rules and market conditions, and provides a theoretical explanation...

This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clark-Groves mechanism, characterize the optimal mechanism that maximizes the weighted...

This paper analyzes a closed, essentially linear polycentric city with homogenous households who probabilistically select their workplace and residence locations. The study utilizes a continuous logit model to describe household location choices. In contrast to the classic urban model with...

Combining a spatial equilibrium model with a matching unemployment model, this paper analyzes the regional quality of life when wages, rents, and unemployment risk compensate for local amenities and disamenities. In particular, the paper shows for quasi-linear utility that the effects of any...

We study a simple model of commuting subsidies with two transport modes. City residents choose where to live and which mode to use. When all land is owned by city residents, one group gains from subsidies what the other loses. With absentee landownership, city residents as a group gain at the...

We study the political economy of commuting subsidies in a model of a mono-centric city with two income classes. Depending on housing demand and transport costs, either the rich or the poor live in the central city and the other group in the suburbs. Commuting subsidies increase the net income...

Although decision processes at the EU level are highly complex and often require unanimity, explicit side payments among member states are unknown. However, logrolling and redistributive policies are substitutes. This paper considers the EU regional policy as a substitute for explicit side...

A pay-as-you-go pension scheme is associated with positive externalities of having children and providing them with human capital. In a framework with heterogeneity in productivity, and stochastic and endogenous investment in fertility and education, we discuss internalization policies...
