We show that social proof - using the actions of others to infer the value of a course of action - creates information cascades in which decision makers initiate coverage of a firm when peers have recently begun coverage. Analysts that initiate coverage of a firm in the wake of a cascade are particularly prone to overestimating the firm`s future profitability, however, and they are subsequently more likely than other analysts to abandon coverage of the firm. We thus find evidence for a cycle of imitation-driven choice followed by disappointment and abandonment. Our account suggests that institutionalization rooted in imitation is likely to be fragile
