About this lecture - Parameter estimates in misspecified models often converge to pseudo-true parameter values, which minimize a population objective function. Pseudo-true values often differ from quantities of economic interest, raising questions of how, if at all, they are relevant for decision-making. To study this question we consider Bayesian decision-makers facing a population minimum distance problem. Within a class of priors motivated by the minimum distance objective, we characterize prior sequences under which posteriors concentrate on the pseudo-true value. This convergence is fragile to small changes in priors, implying that pseudo-true values are relevant for decision-making only in special cases. Constructive results are nevertheless possible in this setting, and we derive simple confidence intervals that guarantee correct average coverage for the true parameter under every prior in the class we study, with no bound on the magnitude of misspecification.

About the Hicks Lecture Series


The Sir John Hicks Memorial Lecture has run since 1998. 


Sir John Hicks was one of the most foremost and influential economists of the 20th Century. In 1946, Hicks returned to Nuffield College as a Research Fellow (1946–1952) and went on to become Drummond Professor of Political Economy (1952–1965) and finally as a research fellow of All Souls College (1965–1971), where he continued writing after his retirement.
