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,...

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...

Higher sales tax in the home country relative to a neighboring country creates a huge incentive for consumers who live closer to the border to purchase goods across the border. Using a unique panel dataset of consumer financial transactions, we find that, when facing higher domestic sales tax,...

We study how the presence of short sellers affects the incentives of the insiders to trade on negative information. We show it induces insiders to sell more (shares from their existing stakes) and trade faster to preempt the potential competition from short sellers. An experiment and...

This paper investigates the role of speculators in the housing market, specifically their contribution to price overreaction through positive feedback trading (or momentum trading). We exploit a unique dataset of condominium transactions in a residential real estate market where transaction...

We document a substantial customer complaint gap between stock and mutual financial firms. To assess whether this 21% per year complaint gap stems from complaint-prone customers in stock insurers, we examine state-adjudicated complaint success. To further delineate between customer selection or...
