Competition and Quality: Evidence from High-Speed Railways and Airlines
Hanming Fang, Long Wang, Yang Yang, Aug 05, 2020This paper investigates whether competition spurs quality improvement using the entry of Beijing-Shanghai high-speed rail (HSR) as an exogenous increase in competition to affected flights to destination cities along the HSR line. We find that competition from the entry of HSR leads to significant reductions in the mean and variance of travel delays on the affected airline routes and that these improvements are mainly driven by reductions in departure delays and the duration of taxi-in time at the destination airport.
Innovation versus imitation: Where all that Chinese R&D is going
Michael König, Zheng (Michael) Song, Kjetil Storesletten, Fabrizio Zilibotti, Jan 26, 2022China is aiming to become a technological innovation powerhouse by 2050, with Premier Li Keqiang recently announcing an increase in R&D investments by 7% for the next five years. But greater R&D investment is no guarantee of success. This column examines the effects of R&D investments by Chinese firms on aggregate productivity and growth.
The Effects of a Multifaceted Poverty-Alleviation Program on Rural Income and Household Behavior in China
Rui Li, Hong Song, Jun Zhang, Junsen Zhang, Feb 12, 2025This study examines the effects of a government-led, large-scale, multifaceted poverty-alleviation program on rural income in China. We find that the program has a positive impact on national key poor counties, with a 10.9% increase in rural income. This effect mainly arises via industrial support, agricultural development, and public service improvement. Strategies that are consistent with local comparative advantages and incentivize local officials to reduce poverty yield more significant effects. Household-level analyses suggest that the program changes household income and expenditure, and the effects are particularly substantial for the poorest households. The study provides novel insights and policy implications for China’s recent experience with poverty alleviation.
Social Media Engagement Increases Government Action, Decreases Pollution
Mark Buntaine, Michael Greenstone, Guojun He, Mengdi Liu, Shaoda Wang, Bing Zhang, Dec 14, 2022In China, citizen participation in environmental governance via social media could significantly improve regulatory effort, leading to substantial environmental benefits.
Trade Policy Uncertainty and Firm Innovation
Qing Liu, Hong Ma, May 12, 2021This study proposes a novel channel through which trade liberalization may induce innovation through the reduction of trade policy uncertainties (TPU) in destination markets. To verify this link, we utilize the significant reduction of TPU engendered by China's accession to the World Trade Organization (WTO) in 2001 as a quasi-natural experiment. We find that reduction in TPU significantly encourages firms' patent applications and that firms' innovation responses to TPU reduction vary by productivity, ownership, exporting status, and the irreversibility of investment.
