Econometrics, the application of statistical and mathematical theories to test hypotheses, is fundamental to applied economics research. Faculty in our department apply state-of-the-art quantitative and econometric tools in all of our research. However, several of our faculty have focused their research on developing and applying new econometric techniques to the issues of causal identification and out-of-sample forecasting. We apply these new techniques in econometrics to address real-world business and policy issues such as measuring heterogeneity in returns to technology adoption, determining factors of risk in consumer credit markets, quantifying the size and sources of risk in agricultural production, and estimating water price elasticities of residential water demand.
