Tax-Brain

Tax-Brain provides a one-stop-shop for tax policy analysis by serving as an interface for multiple tax models. The user specifies a policy reform, economic or behavioral assumptions, some data, and Tax-Brain takes care of the rest.

Tax-Brain handles any interaction between the models it wraps and makes it easy for the user to access data and build tables and graphs.

Tax-Brain is centered around the TaxBrain object. This object has a number of inputs to allow the user to conduct their specific analysis:

  • start_year: First year of the analysis.
  • end_year: Last year in the analysis
  • microdata: Either a Pandas DataFrame containing micro-data or a path to a file containing micro-data.
  • use_cps: A boolean value indicated whether to use the CPS file included in Tax-Calculator.
  • reform: A JSON file or dictionary in the style used by Tax-Calculator containing an individual income or payroll tax policy reform.
  • behavior: Individual behavior assumptions as used by the Behavior-Response model.
  • assump: A JSON file or dictionary containing economic assumptions as used by Tax-Calculator.
  • verbose: A boolean indicator indicated whether or not to write progress report messages as the models run.

Once the TaxBrain object has been initialized, all the user needs to do is use the run() method and everything else is handled internally. BY analyzing the user's inputs, TaxBrain determines if it should run a static or dynamic analysis, which years to run the analysis for, and which data to save as the models run.

After the models have run, the user has easy access to the saved data and can create their own graphs and tables, or use the built in methods to create them.
