Will arbitrage capital flow into markets experiencing shocks, mitigating adverse effects on price efficiency? Not necessarily. In a dynamic model with privately informed capital-constrained arbitrageurs, price efficiency plays a dual role, determining both the profitability of new arbitrage and...

We analyze the extent to which investors in opaque markets price information from more transparent markets. Exploiting the natural experiment created by bond-insurer insolvency, we show that municipal bond investors ignore insurers' equity prices and CDS premia, yet react to insurers'...

We study information acquisition in dealer markets. We first identify a one-sided strategic complementarity in information acquisition: the more informed traders are, the larger market makers' gain from becoming informed. When quotes are observable, this effect in turn induces a strategic...

Behavioral biases like disposition effect and overconfidence have received much attention as a potential driver of numerous anomalies observed in the markets. Also, it has been argued that information uncertainty tends to exacerbate these biases and induce stronger irrational behavior among...

This paper studies information aggregation in financial markets with recurrent investor exit and entry. I consider a dynamic general equilibrium model of asset trading with private information and collateral constraints. Investors differ in their aversion to Knightian uncertainty: When...

This paper examines the relation between investor overconfidence and the idiosyncratic volatility of stock returns. We use investor sentiment, stock turnover, stock misvaluation, and institutional ownership to measure the influence of investor overconfidence on stocks, and find that...

We track trading activity in the days preceding acquisition announcements for target firms, and find that abnormally high trading volume precedes significant price movement. Using additional intraday data, we find increased active-selling in target stocks before acquisition announcements that...

I examine the demand for public information by local and nonlocal investors. Using novel data on institutional investors’ requests for financial information from the SEC, I document that investors acquire approximately 20% more financial information for their local investments. This pattern...

We investigate how informational frictions affect trading in decentralized markets in theory and in a laboratory setting. Subjects, matched pairwise at random, trade divisible commodities that have different private values for a divisible asset with a common value (interpreted as money). We...

Recent research finds that investors, broadly defined, react to the linguistic tone of quarterly earnings conference calls; there is a positive relation between firms' stock returns and call tone (a measure of “sentiment” related word tabulations). However, this type of soft information can...
