This grant renews funding for a set of predoctoral fellowships in energy economics. In each of the past three academic years, Meredith Fowlie (University of California, Berkeley) and Ryan Kellogg (University of Chicago) have led a committee that solicits applications and selects a number of young academics for these two-year predoctoral fellowships. Selected fellows are generally in the final two years of their doctoral program and are conducting one or more studies examining different dimensions of the energy system. Previous fellows have come from an array of universities, including the University of Tennessee; University of Wisconsin, Madison; University of California, San Diego; and Cornell University, among others. The announcement for predoctoral fellowship applications is shared widely within the economics community, and the selection committee has received approximately 20 high-quality applicants each year. Funds from this grant will fund an additional two cohorts of three fellows each. In addition to covering stipend and tuition coverage, a small amount of money is provided for purchasing necessary data and for travel to professional meetings.
