Choice between different versions of a game may provide a means of sorting, allowing players with different preferences to self-select into groups of similar types. We experimentally investigate whether auctioning off the right to play a prisoner's dilemma game in which the cost of unilateral...

Dieser Diskussionsbeitrag kommentiert Güths axiomatische Begründung der Zweit-Preis-Auktion. In diesem Zusammenhang wird auch Güths umfangreiche Analyse der Lambda-Auktion durch eine einfache und anschaulich interpretierbare Lösung ersetzt.

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,...

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....

Similar to Levati and Neugebauer (2001), a clock is used by which participants can vary their individual contributions for voluntarily providing a public good. As time goes by, participants either in(de)crease their contribution gradually or keep it constant. Groups of two poorly and two richly...

Can a court system conceivably control opportunistic behavior if judges are selected from the same population as ordinary citizens and thus are no better than the rest of us? This paper provides a new and, as we claim, quite profound rational choice answer to that unsolved riddle. Adopting an...

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...

On a homogeneous oligopoly market informed sellers are fully aware of market demand whereas uninformed sellers only know the distribution. We first derive the market results when sellers are risk averse, similarly to Ponssard (1979) who assumed risk neutrality throughout. With the help of these...

One of the long-standing puzzles in economics is why wages do not fall sufficiently in recessions so as to avoid increases in unemployment. Put differently, if the competitive market wage declines, why don't employers simply force their employees to accept lower wages as well? As an alternative...

The public management of stock pollutants is an intertemporal problem; today's optimal choice takes the behavior of future governments into account. If a government expects a successor with different environmental preferences - for instance, if Conservatives expect green successors - it must...
