|July 2019||China’s Industrial Policy: an Empirical Evaluation|
with Panle Jia Barwick, Myrto Kalouptsidi: w26075
Despite the historic prevalence of industrial policy and its current popularity, few empirical studies directly evaluate its welfare consequences. This paper examines an important industrial policy in China in the 2000s, aiming to propel the country’s shipbuilding industry to the largest globally. Using comprehensive data on shipyards worldwide and a dynamic model of firm entry, exit, investment, and production, we find that the scale of the policy was massive and boosted China’s domestic investment, entry, and world market share dramatically. On the other hand, it created sizable distortions and led to increased industry fragmentation and idleness. The effectiveness of different policy instruments is mixed: production and investment subsidies can be justified by market share consideration...
|June 2018||The Morbidity Cost of Air Pollution: Evidence from Consumer Spending in China|
with Panle Jia Barwick, Shanjun Li, Deyu Rao: w24688
Developing and fast-growing economies have some of the worse air pollution in the world, but there is a lack of systematic evidence on the health especially morbidity impact of air pollution in these countries. Based on the universe of credit and debit card transactions in China from 2013 to 2015, this paper provides to our knowledge the first analysis of the morbidity cost of PM2.5 for the entire population of a developing country. To address potential endogeneity in pollution exposure, we construct an instrumental variable by modeling the spatial spillovers of PM2.5 due to long-range transport. We propose a flexible distributed-lag model that incorporates the IV approach to capture the dynamic response to past pollution exposure. Our analysis shows that PM2.5 has a significant impact on ...
