Professor Tang’s received his PhD from Northwestern University and has taught here at Penn since 2008. His research focuses on the robust econometric inference of economic models about agents’ behavior in environments with or without strategic interactions. Empirical researchers are mainly interested in two (logically sequential) questions as they try to link economic models with observed data. First, does the theoretical model imply any restrictions on agents’ behavior observable to empirical researchers? Second, given data consistent with a certain class of models, can researchers use the observed data alone to fully recover the unknown primitives of the model? Answers to the first question shed lights on the falsifiability (testability) of an economic model, and help researchers decide whether a certain model is fit for explaining the observed data and predicting future outcomes. Answers to the second question are important if researchers are interested in backing out the unknown structural parameters for the purposing of inferring counterfactual policy implications. A unifying theme of his research is to address these two questions for various economic models while trying to employ as few exogenous form restrictions on model primitives as possible.
