NBER Working Papers and Publications

May 2020The Cost of Privacy: Welfare Effects of the Disclosure of COVID-19 Cases
with David O. Argente, Chang-Tai Hsieh: w27220
South Korea publicly disclosed detailed location information of individuals that tested positive for COVID-19. We quantify the effect of public disclosure on the transmission of the virus and economic losses in Seoul. The change in commuting patterns due to public disclosure lowers the number of cases by 200 thousand and the number of deaths by 7.7 thousand in Seoul over two years. Compared to a city-wide lock-down that results in the same number of cases over two years as the disclosure scenario, the economic cost of such a lockdown is almost four times higher.
January 2019High-Skill Immigration, Innovation, and Creative Destruction
with Gaurav Khanna
in The Roles of Immigrants and Foreign Students in US Science, Innovation, and Entrepreneurship, Ina Ganguli, Shulamit Kahn, Megan MacGarvie, editors
Economists have identified product entry and exit as a primary channel through which innovation impacts economic growth. In this paper, we document how high-skill immigration affects product reallocation (entry and exit) at the firm level. Using data on H-1B Labor Condition Applications (LCAs) matched to retail scanner data on products and Compustat data on firm characteristics, we find that H-1B certification is associated with higher product reallocation and revenue growth. A ten percent increase in the share of H-1B workers is associated with a two percent increase in product reallocation rates – our measure of innovation. These results shed light on the economic consequences of innovation by high-skill immigrant to the United States.
