A leverage-based model of speculative bubbles

Abstract: This paper develops a model of credit-driven bubbles and asks when it gives rise to the patterns that policymakers often use to gauge the presence of a bubble. The model suggests patterns like rapid price appreciation and speculative trade do not always occur whenever a bubble is present, but they do occur when assets are especially overvalued. The model also has implications as to what type of contracts will be used to finance the purchase of bubble assets. These predictions are consistent with observations on credit terms during historical episodes often suspected to be bubbles.
