In this paper I define an evolutionary stability criterion for learning rules. Using Monte Carlo simulations, I then apply this criterion to a class of learning rules that can be represented by Camerer and Ho's (1999) model of learning. This class contains perturbed versions of reinforcement and...

In this paper, I analyze stochastic adaptation in finite n-player games played by heterogeneous populations of myopic best repliers, better repliers and imitators. In each period, one individual from each of n populations, one for each player role, is drawn to play and chooses a pure strategy...

In t-solutions, quantal response equilibria based on the linear probability model as introduced in R.W. Rosenthal (1989, Int. J. Game Theory 18, 273-292), choice probabilities are related to the determination of leveling taxes. The set of t-solutions coincides with the set of Nash equilibria of...

We examine a number of personnel practices, laws and regulations that lower the supply of labor in the Japanese economy. Broadly speaking, there are two kinds of impediments, those that restrict the movement of labor between firms, and those that discourage women from participating to a greater...

Based on direct information on hires and separations for 11.000 establishments during 11 years, we report new evidence that around half of job and worker flows stem from temporary contracts which account for only around 10 percent of employment. The share of temporary contracts is positively...
