In this paper, we consider K finite populations of boundedly rational agents whose preferences and information differ. Each period agents are randomly paired to play some coordination games. We show that several ``special`` (fixed) agents lead the coordination. In a mistake-free environment, all...

Lottery and raffle mechanisms have a long history as economic institutions for raising funds. In a series of laboratory experiments we find that total spending in raffles is much higher than Nash equilibrium predicts. Moreover, this overspending is persistent as the number of participants in the...

We study Tullock's (1980) n-player contest when each player has an independent probability 0 p 2 individual equilibrium spending as a function of p is single-peaked and satisfies a single-crossing property for any two different numbers of potential players. However, total equilibrium spending...

We consider Tullock’s contests with reimbursements. It turns out that the winner-reimbursed contest maximizes the net total spending while the loser-reimbursed contest minimizes the net total spending. We investigate properties of contests with reimbursements and compare them with the classic...

We consider lotteries with reimbursements. It turns out that without loss of generality it is enough analyze lotteries where the winner gets her expenses reimbursed. We find that such a lottery (Sad-Loser) has multiple pure-strategy equilibria. We describe all equilibria and discuss their...

This paper analyses an evolutionary version of the Public Good game of Eshel, Samuelson, and Shaked (1998) in which agents can choose between imitation and best-reply decision rules. We describe conditions under which altruistic and spiteful (maximizing) behavior arise: these conditions are...
