Working papers:

Can teaching children about the environment influence household behavior? 2024. With Magnus Söderberg, Mitesh Kataria

Includes two field experiments on environmental education programs in Swedish schools, coupled with household-level administrative waste data to check what effect they had on actual behavior in the households of participating students.

Serial-correlation-robust power calculation for the analysis-of-covariance estimator. 2020.

An applied econometrics paper on power calculation with panel data. Shows how serial-correlation-robust calculations (of the Burlig et al JDE variety) can be made to work for ANCOVA as well, and not just differences-in-differences. Online appendices

Pessimism and overcommitment. 2020. With Margaret Samahita

An earlier iteration of the 2023 lab experiment we eventually published in JEBO.

Work in progress:

Social preferences and environmental externalities. With Pol Campos-Mercade, Florian H. Schneider, and Magnus Söderberg

We combine a measure of prosociality from a survey experiment with both administrative data on recycling behavior and survey measures of self-stated environmental behavior. Can prosociality predict green behavior?
