Marginal Propensity to Consume and the Housing Choice

Abstract

We study the MPC heterogeneity of households in Japan both theoretically and empirically. We build a heterogeneous-agent overlapping-generations general equilibrium model with an illiquid and indivisible housing asset. We show that mortgage debtor exhibits high MPC and households about to upgrade their house exhibit low MPC. Using Japanese household survey data, we empirically support our theoretical predictions.
