Duke University, based in Durham, North Carolina offers a fully funded PhD in Economics. The faculty is dedicated to anchoring all teaching and research firmly in the core disciplines of microeconomics, macroeconomics, and econometrics. Of the approximately 15 new Ph.D. students each year, 90 percent or more receive six years of funding so long as they remain in good academic standing, and the remainder is either supported by external funding sources or are self-supported. The department attempts to develop partial aid programs for such self-supported students through hourly payment for grading papers or tutoring.
