This paper estimates the causal effect of a large language model-based study assistant on student behavior and learning outcomes in a natural field setting with real academic stakes. I design and deploy a course-specific AI assistant (GPT-UAI) for undergraduate econometrics and evaluate it...

This paper develops a framework to analyze partial population experiments, a generalization of the cluster experimental design where clusters are assigned to different treatment intensities. The framework allows for heterogeneity in cluster sizes and outcome distributions. The paper studies the...

Economic experiments have gained popularity in Agricultural Economics. However, challenges in recruitment and acceptance of experimental methods among farmers persist. Surveying 406 Swedish farmers, we explore farmers' attitudes toward different types and features of economic experiments. Only a...

Despite substantial investment in skills training worldwide, evidence for the effectiveness of such interventions in sub-Saharan Africa is still relatively sparse. We contribute to this literature by implementing a multisite randomized controlled trial (RCT) of the Professionalization of...
