We examine a strategic-choice handicap model in which males send costly signals to advertise their quality to females. Females are concerned with the net viability of the male with whom they mate, where net viability is a function of the male's quality and signal. We identify circumstances in...

The paper analyzes the canonical hold-up model of Hart and Moore (1988) under the assumption that the courts can verify delivery of the good by the seller. We show that the first best can be achieved using simple "option contracts" which give the seller the right to decide whether or not trade...

We examine the evolutionary foundations of common equilibrium refinement ideas for extensive form games, such as backward and forward induction, by examining the limiting outcome of an evolutionary process driven by stochastic learning and (rare) mutations. We show that the limiting outcome in a...

This paper introduces a class of signalling games with response intersection to discuss the informational efficiency of a monopolistic financial market. For these games a necessary and sufficient condition for the existence of a fully revealing sequential equilibrium outcomes is derived....
