Code for separable matching models

Here is R code for the Iterative Projection Fitting Procedure (IPFP) code to solve for equilibrium in a Choo and Siow 2006 model of bipartite, one-to-one matching with perfectly transferable utility.

Here are the Python code files and documentation for IPFP solvers for more variants of the Choo and Siow model (with or without singles, homoskedastic and heteroskedastic). I also wrote a Streamlit interactive app to demonstrate the basic model (homoskedastic, with singles).

My coauthor Alfred Galichon (NYU) and Keith O’Hara (Amazon) have developed the TraME library: a set of procedures for Transportation Methods for Econometrics. It allows the user to estimate a much broader class of models. TraME is available on Github. Here are some more specific links:
