Professor Smith's research generally falls under the rubric of economic theory, with interests generally spanning game theory, uncertainty theory, and matching models. Early in his career, he explored repeated games, and currently is focusing on timing games and bargaining. Professor Smith holds a life-long interest in Bayesian learning, where his work has spanned informational herding, the demand for information, dynamic R&D, rational financial timing, and most recently, the political economy of electoral timing. Finally, Professor Smith's work includes search-matching models, where he tries to find surprising implications of either matching economies (why did the Beatles break-up?) or search frictions (when will the best marry the best if it takes time to find mates?) or college choices (where should I apply to?). So far, three of his top published papers have arisen from joint work with students.
