The assumption that decision makers choose actions to maximize their preferences is a central tenet in economics. This assumption is often justified either formally or informally by appealing to evolutionary arguments. In contrast, this paper shows that in almost every game, payoff. maximization...

In this paper, we experimentally investigate the extended game with action commitment of Hamilton and Slutsky (1990). In their duopoly game, firms can choose their quantities in one of two periods before the market clears. If a firm commits to a quantity in period 1 it does not know whether the...

In a recent study Huck and Müller (1998) report that--in contrast to Bagwell's (1995) prediction--first movers in a simple experimental market do not lose their commitment power in the presence of noise. The present note shows that it is the quality of the signal and not the knowledge about the...

We consider an economy composed of two regions. Each of them provides a public good whose benefits reach beyond local boundaries. In case of decentralization, taxes collected by members of a region are spent only on that region's public good. In case of centralization, tax receipts from the two...
