A well—known result from the theory of finitely repeated games statesthat if the stage game has a unique equilibrium, then there is a uniquesubgame perfect equilibrium in the finitely repeated game in which theequilibrium of the stage game is being played in every period. Here Ishow that this...

It is well known that the rock-paper-scissors game has no pure saddle point. Weshow that this holds more generally: A symmetric two-player zero-sum game hasa pure saddle point if and only if it is not a generalized rock-paper-scissors game.Moreover, we show that every finite symmetric...

We show that for many classes of symmetric two-player games, the simple decision rule \imitate-the-best" can hardly be beaten by any other decision rule. Weprovide necessary and sufficient conditions for imitation to be unbeatable and showthat it can only be beaten by much in games that are of...

Sick-pay is a common provision in labor contracts. It insures workersagainst a sudden loss of income due to unexpected absences andhelps them smooth consumption. Therefore, many governments findsick-pay socially desirable and choose to mandate its provision. Butsick-pay is not without its...

It is difficult to disagree with Vernon Smith's (2010) assessment of thestate of the art in experimental economics. It is informed by the experienceof someone who was there, right at the beginning of experimental economics.Some of the problems he discusses, like the frequent failure of backward...

The study of evolutionary dynamics was so far mainly restricted to finite strategy spaces. In this paper we show that this restriction is in most cases unnecessary. We give a mild condition under which the continuous time replicator dynamics are well defined for infinite strategy spaces....

Weekly repo auctions are the European Central Bank's most important policy instrument. Provided that banks bid seriously, these auctions should reveal useful information about banks' liquidity needs and the stance of monetary policy. However 1 as we show in this paper, the applied auction rules...

We show in this paper that none of the existing static evolutionary stability concepts (ESS, CSS, uninvadability, NIS) is sufficient to guarantee dynamic stability in the weak topology with respect to standard evolutionary dynamics if the strategy space is continuous. We propose a new concept,...

In a recent paper Bagwell (1995) pointed out that only the Cournot outcome, but not the Stackelberg outcome, can be supported by a pure Nash equilibrium when actions of the Stackelberg leader are observed with the slightest error. The Stackelberg outcome, however, remains close to the outcome of...
