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...

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...

This paper shows that geographical investor heterogeneity strongly influences sovereign risk. While standard sovereign debt models mainly attribute the absence of sovereign defaults to foreign creditor retaliation, a new theoretical literature argues that domestic creditors also affect borrowing...

Background: The Fracture Intervention Trial (FIT) showed that the bisphosphonate alendronate reduces the risk of fractures in women with low bone mass in the United States. Objective: To estimate the cost-effectiveness (cost per life-year gained and cost per quality-adjusted life-year, QALY,...
