Description

Naszodi, Anna and Francisco Mendonca (2021) A new method for identifying what Cupid's invisible hand is doing. Is it spreading color blindness while turning us more "picky" about spousal education? Arxiv.org, first version (single authored): March 2021, latest version: February 2023, doi: https://arxiv.org/abs/2103.06991 Naszodi and Mendonca (2021) develop a new method, the Generalized Naszodi-Mendonca method (henceforth GNM-method, see Wikipedia) for analyzing marital sorting along multiple traits. (The GNM-method is the generalized version of the NM-method) They apply the GNM-method to construct a set of counterfactual contingency tables for decomposing changes in the prevalence of educational homogamy and racial endogamy in the US between 1960 and 2015. The decompositions alow one to study changes in aggregate marital preferences over spousal education and race from one generation to another. New data points will be added to the counterfactual series as new census data are released (see WWWW.IDIL.LI the webpage of the International Demographic Inequality Lab). The uploaded files allow one to replicate all the calculations in the paper and to apply the GNM-method in other empirical settings as well. The GNM-method is fully implemented in Matlab, and R, while the Stata code implements the NM-method.
