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