1.Separating Ownership and Information（AER2022）

This paper identifies an upside of the separation of ownership and control, typically the source of inefficiencies in the theory of the firm. Because insiders obtain private information by exercising control, the separation of ownership and control leads to a separation of ownership and information. We show that this separation is necessary for efficient trade in the market for corporate control. The analysis reveals how strategic communication between inside and outside shareholders facilitates takeovers by eliciting external bidders' private information. Our results call into question mandatory disclosure requirements during takeovers.

2.Social Media and Mental Health（AER2022）

We provide quasi-experimental estimates of the impact of social media on mental health by leveraging a unique natural experiment: the staggered introduction of Facebook across US colleges. Our analysis couples data on student mental health around the years of Facebook's expansion with a generalized difference-in-differences empirical strategy. We find that the rollout of Facebook at a college had a negative impact on student mental health. It also increased the likelihood with which students reported experiencing impairments to academic performance due to poor mental health. Additional evidence on mechanisms suggests the results are due to Facebook fostering unfavorable social comparisons.

3.Improving Management Through Worker Evaluations: Evidence from Auto Manufacturing（QJE2022）

Using a randomized experiment with an automobile manufacturing firm in China, we measure the effects of letting workers evaluate their managers on worker and firm outcomes. In the treatment teams, workers evaluate their managers monthly. We find that providing feedback leads to significant reductions in worker turnover and increases in team-level productivity. In addition, workers report higher levels of happiness and well-being. The evidence suggests that these results are driven by learning by managers, leading to changes in their behavior and an overall better relationship between managers and workers.

4.Anti-corruption and poverty alleviation: Evidence from China（JEBO2022）

This paper studies how China’s recent anti-corruption campaign affects poverty incidence. Employing five waves of the China Family Panel Studies (CFPS) data, we find the (potential) poor households in counties that are more exposed to the anti-corruption campaign are associated with a significantly higher level of income and a consequently lower probability of being in poverty post-campaign. This finding survives a vast array of robustness checks based on alternative model specifications, measures of key variables, and sample selection criteria. We find supportive evidence for three plausible mechanisms behind the poverty-reducing effect of the anti-corruption campaign: improved access to transfer payment, reduced government expropriation, and enhanced formal credit support. However, no evidence indicates that the campaign has increased the provision of public goods. Additional analyses suggest that non-politically connected and low-income households benefit more. Overall, our study offers a novel perspective to shed light on the political economy of?poverty alleviation?in China.
