gettsim

GETTSIM provides a depiction of the German Taxes and Transfers System that is usable in a wide array of research applications, ranging from complex dynamic programming models to detailed microsimulation studies.

I spent a short time on this project and created the DAG-based backend which allows users to define functions to compute quantities of a tax and transfer system and the backend will figure out the execution order itself.

This allows users to flexibly define their tax and transfer system or modify an existing system by replacing some functions.

The DAG-based backend was finally extracted and transferred into its own package so that everyone can use it and embed into their application. You can find it here: https://github.com/OpenSourceEconomics/dags.
