Human Mobility Restrictions and the Spread of the Novel Coronavirus (2019-nCoV) in China Hanming Fang, Long Wang, Yang Yang, Jun 03, 2020 We provide a rigorous examination of the causal impact of human mobility restrictions, particularly the lockdown of the city of Wuhan on January 23, 2020, on the containment and delay of the spread of the Novel Coronavirus (2019-nCoV) in China. We employ various difference-in-differences strategies to disentangle the lockdown effect on human mobility reductions from other confounding effects, including a panic effect, a virus deterrence effect, and a Spring Festival effect. We find that the lockdown of Wuhan significantly reduced the within-city movements and cross-city migration with Wuhan, and the enhanced social distancing policies in the 63 Chinese cities outside Hubei province have been effective in containing the spread of the novel coronavirus. We also estimate that, had the government not enacted the historic lockdown of the city of Wuhan, the COVID-19 cases in China would be 64.81% higher in the 347 Chinese cities outside Hubei province, and 52.64% higher in the 16 non-Wuhan cities inside Hubei.

This conceals important differences in the value chain: private firms outperform in pig iron...
Corporate Innovation and IPO Interventions Lin William Cong, Sabrina T. Howell, May 20, 2020 The Chinese government has occasionally suspended IPOs, exogenously creating uncertainty about access to public markets for firms already approved to list. We show that suspension-induced delay reduces corporate innovation activity both during the delay and for years after listing.
