European countries and Japan are contemplating more competition in passenger rail service. In the Netherlands, the Ministry of Transport was assigned responsibility for making a recommendation to Parliament for choosing between competition for the rails and competition on the rails. The Ministry...

We investigate contributions to the provision of public goods on a network when efficient provision requires the formation of a star network. We provide a theoretical analysis and study behavior in a controlled laboratory experiment. In a 2x2 design, we examine the effects of group size and the...

We investigate the effects of power on cooperation in repeated social dilemma settings. Groups of five players play either multi-player trust games or VCM-games on a fixed network. Power stems from having the authority to allocate funds raised through voluntary contributions by all members...

We study the electoral impact of biased endorsements in large Poisson elections with two candidates. Under fairly general conditions, we derive analytical approximations for the asymptotic voting equilibria. We show that, when the electorate is sufficiently polarized, manipulating public...

Performance ranking is common across a range of professional and recreational domains. Even when it has no economic consequences but does order people in terms of their social standing, anticipating such performance ranking may impact how people feel and perform. We examined this possibility by...

We investigate a mechanism that facilitates the provision of public goods in a network formation game. We show how competition for status encourages a core player to realize efficiency gains for the entire group. In a laboratory experiment we systematically examine the effects of group size and...
