Derrick Xu

I am an applied microeconomist. My research explores the motives behind prosocial behaviour in contexts such as charitable giving, climate change, and political economy. I enjoy working with unstructured, non-traditional data.

I did my PhD at the University of Bristol and worked briefly at the WZB Berlin Social Science Center as a postdoc.

Publication

Only in My Backyard: The Effect of Flood Exposure on Environmental Behavior

Sole-authored · Journal of Environmental Economics and Management

Do people care more about the environment after climate disasters? I find that those directly affected by flooding do, but most do not change their actions when their neighbours are hit—except for those with strong moral universalist values.

Spillovers in the Charitable Market: Evidence from Reputation Shocks

Sole-authored · Revise & resubmit, Economic Journal

When a big charity is hit by scandal, do people give elsewhere or stop donating altogether? Donors do not give up on giving; instead, they shift support to other similar charities, identified by the words charities use in their missions.

Do Crises Increase Parochial Behavior? Evidence from Donations During Covid

With Esteban Jaimovich and Sarah Smith · Submitted

Does a universal crisis make people more locally focused? We show that donors shifted their giving towards local charities after Covid, more so in harder-hit and cohesive communities. Those more affected also became less responsive to overseas disaster appeals, and places with larger rises in parochialism saw quicker rebounds in wellbeing.
