We consider a model of (spatial) voting with endogenous timing. In line with actual political campaigns, candidates can decide endogenously when and where to locate. More specifically, we analyze endogenous timing in a two-period n-candidate spatial-voting game. We show that this game possesses...

Adopting an evolutionary approach, we explain the conjectural variations firms may hold in duopoly. Given conjectures, firms play the market game rationally. Success in the market game determines fitness in the evolutionary game. Based on linear heterogeneous Cournot and Bertrand competition...

Competition in some product markets takes the form of a contest. If some firms cooperate in such markets, they must decide how to allocate effort on each of their products and whether to reduce the number of their products in the competition. We show how this decision depends on the convexity...

This paper proposes relative profits (RP) as a robust measure of competition. I consider nine different parameterizations of competition and show that more intense competition increases the profits of a firm relative to a less efficient firm. Further, popular competition measures like the...

We model how unemployment benefit sanctions - benefit reductions that are imposed if unemployed do not comply with job search guidelines - affect unemployment. We find that benefit sanctions are more effective in reducing unemployment than an across-the-board reduction in the replacement rate,...

This paper analyses the effects of unemployment insurance (UI) in a model with two sectors where one sector is more risky than the other, in the sense that the probability of becoming unemployed is higher. With risk-averse agents it is the case that, over a range of values of UI, increasing UI...
