B-Tax

Evaluates the effect of US federal taxes on businesses' investment incentives

B-Tax is a model that can be used to evaluate the effect of US federal taxes on the investment incentives of corporate and non-corporate businesses. Specifically, B-Tax uses data on the business assets and financial policy, as well as microdata on individual tax filers, to compute marginal effective tax rates on new investments. In modeling the effects of changes to the individual income tax code, B-Tax works with Tax-Calculator, another open source model of US federal tax policy. B-Tax is written in Python, an interpreted language that can execute on Windows, Mac, or Linux.

OG-USA

Overlapping-Generations Model for Evaluating Fiscal Policy in the United States

OG-USA is an overlapping-generations (OG) model of the economy of the United States (USA) that allows for dynamic general equilibrium analysis of federal tax policy. The model output focuses changes in macroeconomic aggregates (GDP, investment, consumption), wages, interest rates, and the stream of tax revenues over time. Careful documentation of the model--its output, and solution method--is available here and is regularly updated.
