That individuals contribute in social dilemma interactions even when contributing is costly is a well-established observation in the experimental literature. Since a contributor is always strictly worse off than a non-contributor the question is raised if an intrinsic motivation to contribute...

We analyze stochastic adaptation in finite n-player games played by heterogeneous populations containing best repliers, better repliers, and imitators. Individuals select strategies by applying a personal learning rule to a sample from a finite history of past play. We give sufficient conditions...

Interviewing in professional labour markets is a costly process for firms. Moreover, poor screening can have a persistent negative impact on firms' bottom lines and candidates' careers. In a simple dynamic model where firms can pay a cost to interview applicants who have private information...

In this paper, we define an evolutionary stability criterion for learning rules. Using simulations, we then apply this criterion to three types of symmetric 2x2 games for a class of learning rules that can be represented by the parametric model of Camerer and Ho [1999. Experience-weighted...

In many countries, bankruptcy is associated with low recovery by creditors. We develop a model of corporate credit markets in such an environment. Corporate credit is provided by either a bond market or risk-averse banks. Restructuring of insolvent firms happens out of court if in-court...
