چکیده

This paper examines the relation between adjustment patterns and equilibrium selection in laboratory experiments with two types of simple signaling games. One type of game has two Nash equilibria, of which only one is sequential. The other type has two sequential equilibria, only one of them satisfying equilibrium dominance. For each type of game, the results show that variations in the payoff structure, which do not change the equilibrium configuration, generate different adjustment patterns. As a consequence, the less refined equilibrium is more frequently observed for some payoff structures, while the more refined equilibrium is more frequently observed in others.

The Effect of Play Therapy on Psychological Adjustment, Effective Communication with Others and Individual Abilities of Preschool Children

Background & Aims: One of the most important skills in preschool is social skills. In other words, social skills are concerned with empathy, self-efficacy, responsibility and social interaction, psychological adjustment, effective communication with others, and individual abilities. It is very important to learn social skills in childhood. By strengthening social skills in this period, we can s...

Naive Bayesian Learning and Adjustment to Equilibrium in Signaling Games

This paper uses laboratory and simulation techniques to examine behavior in two signaling games with different payoff structures. Each game has two sequential equilibria in pure strategies, one of which is ruled out by standard “refinements.” The behavior of human subjects approaches the more refined equilibrium in one of the games, but it approaches the less refined equilibrium in the other ga...

Axiomatic Theory of Equilibrium Selection in Signaling Games with Generic Payoffs

Three axioms from decision theory select sets of Nash equilibria of signaling games in extensive form with generic payoffs. The axioms require undominated strategies (admissibility), inclusion of a sequential equilibrium (backward induction), and dependence only on the game’s normal form even when embedded in a larger game with redundant strategies or irrelevant players (small worlds). The axio...

Selection-Mutation Dynamics of Signaling Games

We study the structure of the rest points of signaling games and their dynamic behavior under selection-mutation dynamics by taking the case of three signals as our canonical example. Many rest points of the replicator dynamics of signaling games are not isolated and, therefore, not robust under perturbations. However, some of them attract open sets of initial conditions. We prove the existence...

A unified approach to comparative statics puzzles in experiments

Many experimental studies implement two versions of one game for which agents’ behavior is fundamentally different even though the Nash prediction is the same. This paper provides a novel explanation of such findings. Starting from the observation that many of the games under consideration satisfy the strategic-complementarity property, I obtain predictions for the direction of adjustment in re...
