Abstract

The power of the metaphor of contagion – that beliefs, actions, and strategies spread among economic agents like pathogens among biological organisms – causes it to recur in disparate areas of economics. This article focuses on four applications of contagion to economics: social influence or memoryless learning; Bayesian social learning; strategy choice in coordination games; and the spread of crises in international financial markets.
