We exploit a policy reform that exogenously deteriorates mothers’ job prospects. China switched from a one-child policy to two-child in 2016, which increased female workers’ childbearing and caring responsibilities. Using a leading peer-to-peer lending platform targeting college students in...

We study the relation between the presence of superstar firms and college students' major choice. Salient occurrences of superstar performers in an industry are followed by a sharp rise in the number of college students choosing to major in related fields. This cohort effect remains significant...

We examine the actions of financial institutions and firms regarding greenhouse gas emissions. We find that financial institutions around the world reduce their exposure to stocks of high-emission industries after 2015, especially for those located in high-climate-awareness countries, suggesting...

We introduce a simple definition of carbon-intensive firms to measure institutional investors' exposure to the emission intensities of portfolio companies. The definition is based on major emission industry sectors identified by the Intergovernmental Panel on Climate Change (IPCC). All firms in...

We find that people revise their beliefs about climate change upward when experiencing warmer than usual temperatures in their area. Using international data, we show that attention to climate change, as proxied by Google search volume, increases when the local temperature is abnormally high. In...

We apply machine learning techniques and use stock characteristics to predict the cross-section of stock returns in 33 international markets. We conduct a stringent out-of-sample test to examine concerns about overfitting: the models are trained with past U.S. data and used to predict...

I examine the impact of the V-shaped disposition effect, which results in uninformed sales when investors realize large gains and losses. Adverse selection risk is reduced in the presence of more uninformed sales. I show in a model that market makers should post tighter bid-ask spreads and quote...

We examine the efficacy of short sale regulations in Hong Kong, where the list of shortable stocks is managed by regulators and is updated quarterly. While regulators generally cautiously restrict short selling to larger stocks, we show evidence of deviations: some large liquid stocks, which...
