I study asset price amplification in an asymmetric information model. Entrepreneurs issue debt to finance investments in a physical asset. They have private information about their success probabilities. For a given debt level, higher asset prices require entrepreneurs to invest more of their own funds. This makes bad entrepreneurs more reluctant to mimic good ones; as a result, good entrepreneurs increase their equilibrium leverage and invest more, and this amplifies the initial asset price increase. This model generates predictions about the credit market that are qualitatively consistent with existing evidence. Received April 24, 2015; editorial decision June 15, 2016 by Editor Itay Goldstein.

Abstract We study dividend payouts when banks face coordination-based rollover crises. Banks in the model can use dividends to both risk shift and signal their available liquidity to short-term lenders, thus, influencing the lenders’ actions. In the unique equilibrium both channels induce banks to pay higher dividends than in the absence of a rollover crisis. In our model banks exert an informational externality on other banks via the inferences and actions of lenders. Optimal dividend regulation that corrects this externality and promote financial stability includes a binding cap on dividends. We also discuss testable implications of our theory.
