On November 8th, Pierre-André Chiappori will give the Merrick Lecture (4:00-5:00 pm at the Rotunda) and the Bankard Applied Microeconomics seminar (12:00-1:30 pm at Monroe 120). Pierre-André is E. Rowan and Barbara Steinschneider Professor of Economics at Columbia University and a Distinguished Fellow at the Becker Friedman Institute of The University of Chicago. You can see his research here http://www.columbia.edu/~pc2167/
Among many influential contributions to economics, he is particularly well known for (I) economics of collective model (roughly, a collective model is one where the economic unit of interest is a collection of individuals, usually from within a household, and not just one individual as we usually assume) and its application to household consumption and intra-household bargaining; (II) economics of marriage and matching markets; and (III) empirical contract theory.
His Merrick lecture is titled Inequality and Human Capital: A Global View. See the attached flyer. No registration is required for these events.
