Sudden big price changes are followed by periods of high and persistent volatility. I develop a tractable dynamic rational expectations model consistent with this observation. An infinity of agents possess dispersed information about future dividends and trade in centralized markets. Information...

We evaluate the impact of complexity and content of new information on stock return volatility dynamics around 10-K fillings. On average, return volatility increases by 0.4% in the first four weeks after the release of the report, followed by a 2.6% decrease in the subsequent six weeks. This...

This paper studies the choice between building liquidity buffers and raising funding ex post, to deal with liquidity shocks. We uncover the possibility of an inefficient liquidity squeeze equilibrium. Agents typically choose to build smaller liquidity buffers when they expect cheap funding....

We introduce a continuous-time principal-agent model where the agent can privately influence both the drift and diffusion of the cash flows. The total diffusion is the product of the agent's volatility choice and a stochastic volatility process that is unobservable to the principal. This model...

This paper proposes a simple analysis for examining an agent's optimal decisions in a principal-agency problem. Unlike the standard approach, the target firm's expected return and risk are modeled as a parametric curve in terms of a critical business decision. A general condition is derived for...
