New Initiatives

Cost-of-Capital-Calculator

A model that evaluates the effect of US federal taxes on businesses' investment incentives

General updates

OpenFisca-UK

A model of the United Kingdom's tax system based on the OpenFisca platform

Releases and new features

  • Release 0.2.0  â€”  Enriched tax modeling, added tests, and updated API.
  • A UK legislation explorer with a web app for the model's variables, parameters, and formulae.

General updates

  • This is a newly cataloged PSL project!
  • Created with OpenFisca, an open-source computation engine that "makes law computable," OpenFisca-UK is a model of the United Kingdom's tax system.
  • Check out its documentation for a demo that calculates the National Insurance liability by region.

Tax-Brain

An integrator package for multiple open source tax models

General updates

PCI-Crackdown *

A machine learning algorithm that predicts crackdowns on protests by the Chinese military

General updates
