1.Migrants and Firms: Evidence from China（AER2022）

How does rural-urban migration shape urban production in developing countries? We use longitudinal data on Chinese manufacturing firms between 2000 and 2006, and exploit exogenous variation in rural-urban migration induced by agricultural income shocks for identification. We find that, when immigration increases, manufacturing production becomes more labor intensive and productivity declines. We investigate the reorganization of production using patent applications and product information. We show that rural-urban migration induces both labor-oriented technological change and the adoption of labor intensive product varieties.

2.Managers and Productivity in the Public Sector（ECTA2022）

This paper studies the impacts of managers in the administrative public sector using novel Italian administrative data containing an output-based measure of productivity. Exploiting the rotation of managers across sites, I find that a one standard deviation increase in managerial talent raises office productivity by 10%. These gains are driven primarily by the exit of older workers who retire when more productive managers take over. I use these estimates to evaluate the optimal allocation of managers to offices. I find that assigning better managers to the largest and most productive offices would increase output by at least 6.9%.

3.The Dynamics and Spillovers of Management Interventions: Evidence from the Training within Industry Program （JPE2022）

This paper examines the long-term and spillover effects of management interventions on firm performance. Under the Training Within Industry (TWI) program, the US government provided management training to firms involved in war production between 1940 and 1945. Using a newly collected panel data set on all 11,575 US firms that applied to the program, we find that the TWI training had positive and long-lasting effects on firm performance and the adoption of beneficial managerial practices. Moreover, it generated complementarities among different types of training and had positive spillover effects on the supply chain of trained firms.

4.Infrastructure investment and growth in China: A quantitative assessment（JDE2022）

During the period 2003–2016, China’s infrastructure investment as a share of GDP outpaced, by a large margin, the average GDP share of?entire?government investment in advanced, developing, or emerging economies. A dynamic multi-sector model is constructed to assess the growth effects of this extraordinary investment episode. The model features sectoral heterogeneity in infrastructure intensity and positive externalities from aggregate infrastructure for firms and consumers. Along the model’s transition path, infrastructure investment interacts with labor-augmenting technological progress and structural change in China to generate growth. The benchmark results suggest that infrastructure expansion accounts for 14% of China’s average annual growth rate over the period 2003–2016, but the expansion was socially excessive for nearly the entire period. The analysis examines the sensitivity of the results to the strength of infrastructure externality and quantifies the contribution of various factors to infrastructure-driven growth, including crowding out, structural change, and sectoral heterogeneity in infrastructure intensity.

5.The value of time, with and without a smartphone（JEBO2022）

Smartphones can lower the disutility of waiting by increasing productivity and making time pass more pleasantly. We elicit the compensation required by subjects to wait for 30 minutes, alone in an empty room, under four different conditions that varied access to the subject’s?smartphone. Compared to the treatment where subjects had full use of their phone, we find that they required?24%?percent more to wait with the audio features of the phone remaining but the phone physically locked away,?48%?percent more to wait with only an FM radio, and?79%?percent more to wait in a quiet room. We find little correlation between a subject’s wages and her offers, emphasizing the importance of heterogeneity in the?value of time?that is based on context rather than income.

6.The health consequence of rising housing prices in China（JEBO2022）

This paper examines the health consequence of rising housing prices in China by exploiting spatial and temporal variation in housing price appreciation linked to individual-level health data from 2000 to 2011. Using an?instrumental variable?approach, we find that increases in housing prices significantly raise the probability of having chronic diseases. The deep-rooted marriage culture of males being obligated to buy a home before getting married and the growing marriage market competition are the main channels that exacerbate the negative health effects, particularly for parents with marriage-age sons. We also show that increased work intensity, high levels of stress, and lifestyle changes are other possible channels. Our results highlight the unintended health consequences of the?real estate market?prosperity.
