Financial markets enable risk sharing and efficient allocation of capital. We characterize how these roles interact in a “feedback effects” model with diversely informed, risk-averse investors and a manager who learns from prices when making an investment decision. While learning from prices...

Countercyclical dispersion of firm outcomes (micro dispersion) is commonly used as a proxy for micro uncertainty. In this paper, we characterize conditions under which micro dispersion and micro uncertainty co-move positively in the context of a large Cournot economy with dispersed information...

Quarterly earnings conference calls convey fundamental information, as well as manager and analyst opinion about the firm. We examine how market uncertainty regarding firm valuation is affected by conference call tones. Using textual analysis of all publicly available earnings calls (2002-2012)...

In an asset-pricing model, risk-averse agents need to forecast the conditional variance of a stock's return. A near-rational restricted perceptions equilibrium exists in which agents believe prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate...

This paper demonstrates that an asset pricing model with least-squares learning can lead to bubbles and crashes as endogenous responses to the fundamentals driving asset prices. When agents are risk-averse they generate forecasts of the conditional variance of a stock's return. Recursive...

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

This paper demonstrates that an asset pricing model with least-squares learning can lead to bubbles and crashes as endogenous responses to the fundamentals driving asset prices. When agents are risk-averse they need to make forecasts of the conditional variance of a stock¡¯s return....

Using the mutual fund industry as a laboratory, we demonstrate theoretically and empirically that economic policy uncertainty an affect investment decisions through an information rather than real options channel. Specifically, we find that fund flow-performance sensitivity decreases in...

This article aims to build through the collection of inputs from prior research, regulatory input and practitioner's experience, a comprehensive definition of risk.Risk is not measurable uncertainty nor volatility. Risk is a three part concept: (1) risk is the potential that events may have an...

I investigate whether information quality affects the cost of equity capital through liquidity risk. Liquidity risk is the sensitivity of stock returns to unexpected changes in market liquidity; recent asset pricing literature has emphasized the importance of this systematic risk. I find that...
