This paper investigates why subjects in laboratory experiments on quantity precommitment games consistently choose capacities above the Cournot level - the subgame-perfect equilibrium. We argue that this puzzling regularity may be attributed to players' perceptions of their opponents' skill or...

We study the choice of drug for the treatment of high blood pressure (hypertension) in Sweden between 1988-1994. During this time period calcium antagonists and ACE-inhibitors increased their market shares at the expense of the older drugs diuretics and beta-blockers. We use a prescription micro...

A large number of individuals are randomly matched into groups, where each group plays a finite symmetric game. Individuals breed true. The expected number of surviving offspring depends on own material payoff, but may also, due to cooperative breeding and/or reproductive competition, depend on...

The literature on deregulated electricity markets generally assumes available capacities to be given. In contrast, this paper studies a model where firms precommit to capacity levels before competing in a uniform price auction. The analysis sheds light on recent empirical findings that firms use...

A product set of pure strategies is a prep set ("prep" is short for "preparation") if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exists in a class of strategic games satisfying...
