In strictly competitive games, equilibrium mixed strategies are invariant to changes in the ultimate prizes. Dixit & Skeath (1999) argue that this seems counter-intuitive. We show that this invariance is robust to dropping the independence axiom, but is removed if we drop the reduction axiom.

In this paper, we prove that the concept of value traditionally defined in the class of two-person zero-sum games can be adequately generalized to the class of n-person weakly unilaterally competitive games introduced by Kats & Thisse [KT92b]. We subsequently establish that if there exists an...

This paper proposes a general framework for analyzing commodity tax competition under destination and origin principles, based on three possible tax spillovers, the consumer price spillover, the producer price/terms of trade spillover, and rent spillovers. A model is presented which can be...

This paper analyses the relationship between the size of jurisdictions and the degree of redistribution. A simple political economy model with cross-border shopping and limited and impure altruism is developed in order to study how the size of jurisdictions affects both the cost of...

The transfer of sovereign states in a common market is effected by the policy choices of all memeber states. The free mobility of goods and factors of production creates the policy externalities. The European Union, for example, is working towards comletely free movement of citiens between...

In a context where both the poor and the rich are (imperfectly) mobile, this paper compares the Nash equilibrium levels of income redistribution from the rich to the poor when jurisdictions compete either in taxes, in transfers or both. Although taxes and transfers are linked through the...

Successful individuals were frequently found to be overly optimistic. These finding are puzzling, as one could expect that realists would perform best in the long run. We show, however, that in a large class of strategic interactions of either cooperation or competition, the equilibrium payoffs...

The aim of this paper is to propose a model that describes the strategic choices adopted by the firms in the competitive structure of multimedia industry. From a sample of competitors in three large activities of the multimedia (audio-visual, telecommunications, data processing) we build an...
