In the residential housing market, home owners are reluctant to sell in a declining market. We build a model which focuses on the embedded call option associated with home ownership that allows owners to delay the (irreversible) sale. When prices are low, the (opportunity) cost of a sale, i.e.,...

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 use daily transaction data in 214 cities to study the impact of COVID-19 on consumption after China's outbreak in late January 2020. Based on difference-in-differences estimation, daily offline consumption—via UnionPay card and QR scanner transactions—fell by 32%, or 18.57 million RMB per...

We empirically investigate how households reallocate their funds in response to an austere housing-market cooling intervention—the Housing Purchase Restriction (HPR) policy in China—that depresses housing demand. Based on a proprietary dataset on individual stock accounts from a large stock...

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 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...

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...

This paper studies the incentive costs of housing booms. We use the type and actual time stamps of 9.3 million credit card transactions by over 200,000 cardholders from a large commercial bank to detect non-work-related behavior during work hours. After positive shocks to house prices, employees...

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...
