Cost-of-Capital-Calculator

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

General Updates
  • Kyle Pomerleau (AEI) uses Cost-of-Capital-Calculator to simulate the effect of lower capital gains tax rates on the marginal effective tax rate on new investment. Link

OG-USA

An overlapping-generations model for evaluating fiscal policy in the United States

Releases and new features
  • Release 0.6.2
    • Bug fixes for the the baseline_spending=True and open economy configurations.
    • Enhancements to output plots and tables.
    • More clear and concise source code.

ParamTools

A library for parameter processing and validation with a focus on computational modeling projects

Releases and new features

  • Release 0.14.0
    • Add _auto attribute to parameter values that were extended automatically. This makes it possible to update the rules for how parameters should be extended, delete the extended values, and update with the new rules (#102).
    • Add a clobber argument to the adjust method that allows you to toggle whether user-defined values should be overridden while doing an adjustment in extend mode (#102).
    • API change in extend method to use more concise keyword arguments. The argument label_to_extend is now label and the label_to_extend_values is now label_values (#103).
    • Ability to specify the state to be used when converting between lists of value objects and arrays (#105).

Tax-Calculator

A USA federal individual income and payroll tax microsimulation model

Releases and New Features
  • Tax-Calculator adopts ParamTools for parameter processing and validation (#2401). 
General Updates
  • Kyle Pomerleau (AEI) uses Tax-Calculator to analyze the HEROES Act rebates. Link
