I am an Assistant Professor of Economics and Public Affairs at Princeton University, in the Department of Economics and the School for Public and International Affairs.

I study macroeconomics. Two specific themes in my work are understanding the role of bounded rationality and social dynamics in business-cycle fluctuations and modeling how societies adapt to climate change through policy changes and technological innovation.

I received a PhD in Economics from MIT in 2022 and I was a Prize Fellow in Economics, History, and Politics at Harvard University in the 2022-23 academic year. My full CV can be found here. You can contact me at ksastry@princeton.edu.
