The Institute of Empirical Research in Political Economy (IERPE or IREEP in French) was launched on January 7, 2004 by Professor Léonard Wantchékon (Princeton University). IERPE is a not-for-profit institution that specializes in training and empirical research in the evaluation of public policy. Since its inception, IERPE has steadily become a reference point in public policy research and in training at the graduate level in economics and statistics.
