Stable Partnerships, Matching, and Local Public Goods

Abstract

In the presence of local public goods differences in tastes are an important determinant of the way in which partnerships are formed. Heterogeneity in tastes for private vs. public goods produces a tendency to positive assortment and partnerships of couples with similar tastes; heterogeneity in tastes for different public goods brings about partnerships of couples with similar tastes only if there is a significant overlap in the distribution of tastes of the two groups to be matched. We show that with two public goods we may get negative assortment, pure positive assortment being only one of many possibilities.
