In April, 2010, Professor Andrew Postlewaite won the Kravis teaching award for tenured faculty and Professor Flavio Cunha the award for tenure-track faculty, with Cunha winning for the second year in a row! The Kravis prize selections are made each year by a committee of undergraduate students who do extensive polling of Penn undergraduate economics majors. The Joel Popkin Graduate Teaching Prize in Economics was awarded to Stanislav Rabinovich. The Edwin Mansfield Teaching Teaching prize for best performance by a recitation instructor in Introductory Economics was awarded to Mark Bognanni.
