Demo Days

Recent presentations

  • Nate Golden demonstrated the UBI Center's Basic Income Builder web app.
  • Jason DeBacker showcased how to do unit testing for open source projects in R, and the PSL blog has a companion piece about the demo.

Capital-Cost-Recovery

A library with freely available capital cost recovery data across OECD countries

General updates

  • The Capital-Cost-Recovery, newly cataloged in the PSL, is a library developed by the Tax Foundation with freely available data for capital cost recovery---the ability of businesses to recover (deduct) the costs of their investments---across OECD countries.
  • Check out its documentation and a Tax Foundation report for more details about this project.

OG-Core

A general overlapping-generations model for evaluating fiscal policies

Releases and new features

  • This is a newly cataloged library that provides a general framework of overlapping-generations models for evaluating fiscal policies, and it is a dependency of several country-specific OG models, such as OG-USA and OG-UK.
  • Check out its documentation for more details.

PCI-China

A machine learning algorithm that predicts China's policy changes by mining its state-controlled media

Releases and new features

  • 2021 Q2 update  —  Showing no spikes and maintaining the previous prediction about China's possible military aggresions.

General updates

  • Weifeng Zhong discussed the project's prediction about China's military aggressions in the David Webb Show, Freedom Works Radio, and Steel on Steel.

Tax-Calculator

A USA federal individual income and payroll tax microsimulation model
