We show that U.S. analysts alter their behavior in response to a randomly assigned shock that exogenously varies the timeliness and cost of accessing companies' mandatory disclosures in the cross-section of investors: analysts reduce the number of stocks they cover, issue less optimistic and...

We estimate the value added by sell-side equity research analysts and explore the links between analyst research, informational efficiency, and asset prices. We identify the value of research from exogenous changes in analyst coverage. On announcement that a stock has lost all coverage, share...

Limits to arbitrage play a central role in behavioral finance. They are thought to interfere with arbitrage processes so that security prices can deviate from true values for extended periods of time. We describe a recent financial innovation that allows limits to arbitrage to be sidestepped,...

This paper analyzes the determinants of buyout funds' investment decisions. In a model in which the supply of capital is "sticky" in the short run, we link the timing of funds' investment decisions, their risk-taking behavior, and the returns they subsequently earn on their buyouts to changes in...

Is greater trading liquidity good or bad for corporate governance? We address this question both theoretically and empirically. We solve a model consisting of an optimal IPO followed by a dynamic Kyle market in which the large investor's private information concerns her own plans for taking an...

We examine to what extent institutional frictions such as short-sale constraints deter entry into informational arbitrage ex ante and reduce informational efficiency ex post. We focus on small arbitrageurs who target hard-to-short companies with correspondingly high potential for overvaluation....

We document the existence of a strategy designed to circumvent limits to arbitrage. Faced with short-sale constraints and noise trader risk, small arbitrageurs publicly reveal their information to induce the target's shareholders (the longs) to sell, thereby accelerating price discovery. Using...

We solve a dynamic Kyle model in which the large investor's private information concerns her plans for taking an active role in governance. We show that once a block has been created, its continued existence is jeopardized by an increase in the liquidity of the firm's stock. Greater liquidity...

We examine to what extent institutional frictions such as short-sale constraints deter entry into informational arbitrage ex ante and reduce informational efficiency ex post. We focus on small arbitrageurs who target hard-to-short companies with correspondingly high potential for overvaluation....

We analyze the determinants of buyout funds' investment decisions. We argue that when the supply of capital is lsquo;sticky' in the short run, the timing of funds' investment decisions, their risk-taking behavior, and their subsequent returns depend on changes in the demand for private equity,...
