New analysis of @KamalaHarris's Child Tax Credit proposal:

* $117B cost in 2025
* Benefits 44% of population
* Cuts child poverty by 31%
* Reduces Gini index by 1.4%

Behavioral responses shift these numbers by 5-6%.

ICYMI, @MaxGhenis and @nikhil_woodruff gave a great demo of a new feature in @ThePolicyEngine; the ability to analyze behavioral responses to incentives implicit in the tax-benefit system.

Tax-Calculator users: Version 4.0.0 has just been released on @pypi and @condaforge!

There are a number of new enhancements, such as the separation of the employer and employee portion of payroll taxes (useful e.g. to analyze payroll tax offsets)

ICYMI, check out @bodi_yang on the payroll tax calculator model he developed @OSPCatAEI on YouTube. A great presentation on the OSPC models and this new tool to correctly account for payroll tax offsets when doing revenue estimates.
