Procedural Formalism and Social Networks in the Housing Market

Abstract

Why do some OECD countries have high levels of procedural formalism (PF) in the housing market? We provide an explanation based upon complementarities between the strength of social networks and the stringency of procedural formalism. The interest of social networks is that conflict resolution is independent of the law. When local people belong to social networks whereas foreigners do not, PF may facilitate housing search for locals at the expense of foreigners. To illustrate this mechanism we build a search-theoretic model of the housing market. The model emphasizes that the support for PF increases with the size of social networks, the default probability on the rent, the proportion of foreigners, and market tightness.
