OG-USA-Calibration is a package that provides code and data to calibrate an overlapping-generations (OG) model, OG-MOD, to the economy of the United States (USA). Together, OG-MOD + OG-USA-Calibration make the OG-USA model that allows for dynamic general equilibrium analysis of federal fiscal policy in the United States. The model output focuses changes in macroeconomic aggregates (GDP, investment, consumption), wages, interest rates, and the stream of tax revenues over time. This documentation of the OG-USA-Calibration package contains the following major sections, which are regularly updated.
