Working papers:

Social preferences and environmental externalities. 2025. With Pol Campos-Mercade, Florian H. Schneider, and Magnus Söderberg.

We conduct a survey experiment where respondents play a game to elicits their degree of prosociality. We then show that this prosociality measure predicts actual waste behavior in administrative data on household waste, as well as a range of self-stated pro-environmental behaviors.

Can teaching children about the environment influence household behavior? 2025. With Magnus Söderberg, Mitesh Kataria. Accepted at The Scandinavian Journal of Economics.

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:

The economics of waste behavior: Evidence from individual data. With Magnus Söderberg, Marica Valente

A model of moral consistency, self-image, and pro-environmental behavior. With Jérôme Pivard
