About Me
I am a fifth-year Ph.D. student in the Economics Department at Cornell University. I work on macroeconomics, environmental economics, firm dynamics, and information economics. I obtained a BA in Economics from Cornell in 2021.
Three specific topics that I am studying are (1) the origins of capital misallocation, (2) the aggregate consequences of climate change and climate policies, and (3) the propagation of shocks and risks in production networks. My research tries to answer macro questions using micro data.
My full CV can be found here. You can contact me at zx88@cornell.edu.
