In this paper we propose a three-level computational equilibrium model that allows to analyze the impact of the regulatory environment on transmission line expansion (by the regulator) and investment in generation capacity (by private firms) in liberalized electricity markets. The basic model...

We experimentally investigate a Bertrand market with homogenous goods where sellers may behave socially responsible by donating a share of their profits to an existing non-profit organization. In our experiment, we find that this Corporate Social Responsibility (CSR) component is used...

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 Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...

"Empirical studies indicate that the gender wage gap is lower under collectively negotiated contracts than in firms not bound by such contracts. It is, however, a largely open question, how the organization and the process of collective negotiations affect the gender wage gap. In the period from...
