I am an applied microeconomist, with a PhD from Bristol. 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.

Publications

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

Sole-authored · Journal of Environmental Economics and Management

Summary

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.

Working Papers

Spillovers in the Charitable Market: Evidence from Reputation Shocks

Sole-authored · Revise & resubmit, Economic Journal

Summary

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

Summary

Does a universal crisis localise giving? After Covid, donors shifted to local charities, especially in harder-hit, ethnically homogeneous communities, while responding less to overseas appeals, and areas with greater parochialism rebounded faster in wellbeing.
