My research interest is empirical corporate finance with a focus on ESG and corporate investment. My job market paper studies the relationship between government contracting and corporate environmental policies. Using a new data set of government contracts, I show that firms that supply government agencies engage in more emission-source reduction activities when government agencies increase their overall preference for "green" suppliers. Analyses using a public procurement reform in European Union provide causal evidence. Additionally, I document stronger effects when firms face higher climate policy uncertainty and external financing dependence. Overall, the results illustrate the economically large impact of government contracting in stimulating firms’ investments in environmentally friendly technologies and production methods.
