Heterogeneous preferences of Russian residential mortgage borrowers

Abstract

Purpose This paper aims to examine the heterogeneity of preferences of mortgage borrowers of Russian state-owned suppliers of residential housing mortgages. Design/methodology/approach Analysis takes into account the underwriting process and the choice of contract terms of all loans originated from 2008 to 2012. The data set contains demographic and financial characteristics for all applications, loan terms and the performance information for all issued loans by one regional bank which operates government mortgage programs. The paper uses a multistep semiparametric approach to estimate the determinants of bank and borrower choice controlling for possible heterogeneity of preferences, sample selection and endogeneity of contract terms. Findings The study found that the demand of low-income households who are unable to afford to improve the housing conditions by other instruments than government mortgage is less elastic according to the change both in interest rate and maturity compared with higher-income households. Social implications Given lower elasticities of the demand, the low-income group of borrowers has higher potential cost of loan and is usually rejected by commercial banks. The presence of the Agency of Housing Mortgage Lending special programs with subsidized interest rate for special constrained categories (young families, teachers, researchers etc.) widens the access for housing conditions’ improvements as a part of housing affordability government program. Originality/value The main contribution to the literature is modeling choice of contract terms as interdependent by the structural system of simultaneous equations with heterogeneous marginal effects.
