Topics course.: Many countries today face rapidly aging populations. The economic consequences will pose enormous challenges to policymakers. What are the implications of an aging population for the sustainability of pension funds and health care systems? for labor force growth and productivity growth? for savings and asset markets? for the demand for public and private goods? What policy options have economists offered to deal with these issues? In this seminar we study these questions and more from both microeconomic and macroeconomic perspectives. Prerequisites: ECO 250, ECO 253 and ECO 220. Enrollment limited to 15.
