House-Price Dynamics and Effects on the Macro Economy

Abstract

The first part of this chapter draws on 12 waves of Japanese household longitudinal data (Keio Household Panel Survey, KHPS) and estimates a conditional fixed effects logit model to investigate the effects of housing equity constraints and income shocks on own-to-own residential moves in Japan by comparing the effects between 2004 to 2008 and 2009 to 2014. By looking at contemporaneous extended Loan-to-Value (ELTV) and extended Debt-to-Income (EDTI) ratios under the recourse-loan system, we examine whether housing equity constraints and negative income shocks have any impact on own-to-own residential moves and whether there is any difference between the two periods. Taking account of the specific nature of the recourse-loan system in Japan, we further investigate whether these effects differ between positive and negative equity households. The estimation results show that housing equity constraints and negative income shocks significantly deter own-to-own residential moves for positive equity households even in recent financial-easing periods. In the latter part of this chapter, we use Japanese prefectural-level data to analyze the relationship between borrowing patterns and house price dynamics under the recourse-loan system. Our principal finding is that, in prefectures where homeowners are highly leveraged (i.e., have high and extended loan-to-value ratios), house prices respond less sensitively than they do in prefectures where lower leveraged homeowners are common. This finding based on the recourse-loan system is quite different from the finding under the non-recourse-loan system, because under the recourse-loan system, the lock-in effect stemming from severe equity constraints is much more severe.
