A growing empirical literature has come to the intriguing conclusion that institutional herding positively predicts short-term returns but negatively predicts long-term returns. We...

In this paper we develop a simple theoretical model to analyze the impact of institu- tional herding on asset prices. A growing empirical literature has come to the intriguing conclusion that institutional herding positively predicts short-term returns but nega- tively predicts long-term...
