This paper develops a framework to study general equilibrium implications for an economy in which agents are allowed to have dynamically inconsistent time and risk preferences. This framework accommodates, but is not limited to, the following settings: (1) non-exponential discounting; (2)...

I study the effects of risk and ambiguity (Knightian uncertainty) on optimal portfolios and equilibrium asset prices when investors receive information that is difficult to link to fundamentals. I show that the desire of investors to hedge ambiguity leads to portfolio inertia and excess...

This note investigates the impact of investors' memory limitations on stock-market prices. I consider a simple asset-pricing model in which investors allocate limited cognitive resources to retrieve information from memory and to learn about the data generating process of multiple assets. I show...

We test and offer support to Merton's (1987) theory that difference in a stock's investor recognition affects its cost of capital. In the U.S. market, using the breadth of ownership among retail investors as a proxy for investor recognition, we show that a long-short portfolio based on the...

We devise a tractable model to study the buyer's bid double auction (BBDA) that allows correlated signals and interdependent values/costs. We demonstrate that simple, easily calculated equilibria exist in small markets. We prove that the incentive for strategic behavior vanishes at a O (1/η)...

News sentiment has been empirically observed to have impact on financial market returns. In this study, we investigate firm-specific news from the Thomson Reuters News Analytics data from 2003 to 2014 and propose an optimal trading strategy based on a sentiment shock score and a sentiment trend...

News sentiment has been empirically observed to have impact on financial market. However, finding a clear predictor of market returns using news sentiment remains a challenging task. This study investigates the relationship between news sentiment and cumulative market returns and volatility. We...

This paper provides a new empirical strategy for testing models of information choice based on observing which types of information are consumed and incorporated into asset prices. Consistent with the predictions of the information driven comovement hypothesis (Veldkamp 2006), we find that stock...

I develop a search-and-bargaining model of endogenous intermediation in over-the-counter markets. Unlike the existing work, my model allows for rich investor heterogeneity in three simultaneous dimensions: preferences, inventories, and meeting rates. By comparing trading-volume patterns that...

The US Treasury effectively ”owns” about 24% of the stocks held by high income US taxable investors. Through the capital gains tax, Uncle Sam has an effective exposure of more than $1 trillion of equities. And this huge-but-silent investor might be about to get a lot bigger if capital gains...
