The analysis explores Bayes-rational sequential decision making in a game with pure information externalities, where each decision maker observes only her predecessor’s binary action. Under perfect information the martingale property of the stochastic learning process is used to establish convergence of beliefs and actions. Under imperfect information, in contrast, beliefs and actions cycle for...
This paper studies a simple model of observational learning where agents care not only about the information of others but also about their actions. We show that despite the complex strategic considerations that arise from forward-looking incentives, herd behavior can arise in equilibrium. Our results have application to understanding momentum in sequential elections, and inefficiencies in sequ...
Individual actions such as the purchase of a machine or the changing or a price are often discrete and infrequent. Macroeconomic models, however, often ignore this intermittent behavior. In this paper, we present conditions under which a representative agent model, which ignores discrete adjustment on the individual level, is observationally equivalent to a model that takes discrete adjustment ...
Convergent evidence from functional imaging and from neuropsychological studies of basal ganglia disorders indicates that the striatum is involved in learning to categorize visual stimuli with feedback. However, it is unclear which cognitive process or processes involved in categorization is or are responsible for striatal recruitment; different regions of the striatum have been linked to feedb...
BACKGROUND AND OBJECTIVES Conditioned fear may emerge in the absence of directly experienced conditioned stimulus (CS)--unconditioned stimulus (US) pairings. Here, we compared three pathways by which avoidance of the US may be acquired both directly (i.e., through trial-and-error instrumental learning) and indirectly (i.e., via verbal instructions and social observation). METHODS Following fe...
