Housing wealth effects for private and subsidized homeowners

This paper aims to examine the effect of housing wealth on household consumption when there are resale and refinancing constraints that prevent housing assets from being cashed out.

Based on Household Expenditure Survey data in Hong Kong from 1999 to 2010, regression analysis is applied to compare the housing wealth effects of private and subsidized homeowners. Propensity score matching is adopted to ensure that the two groups of homeowners share similar household income. Further regression analysis is conducted to examine private homeowners’ consumption when their recourse mortgages are in negative equity.

Subsidized homeowners, who are not allowed to resell their units before sharing their capital gain with the government, experienced an insignificant housing wealth effect. While private homeowners experienced a significant housing wealth effect, the effect was weakened in the presence of a resale constraint induced by negative equity. The results remain robust after the application of more rigorous sample selection through propensity score matching.

The analyses are subject to two potential data limitations. One is a relatively small sample size. The other is that data on financial assets and mortgages are unavailable and have to be indirectly controlled through household characteristics. Nevertheless, our estimated marginal propensity to consume out of housing wealth is 0.03 of the annual household consumption for private homeowners, which is within the range of estimates reported in previous literature.

This study shows that the housing wealth effect enjoyed in the private sector does not necessarily apply to the subsidized sector where resale and refinancing constraints exist. This is not to suggest that the constraints be removed. Rather, policymakers should be aware of the tradeoff: while the constraints ensure that government subsidies are used to assist home ownership, not capital gain, they also bring about consumption inequality in a society, especially in a booming housing market.

Our findings extend the literature on the housing wealth effect, which has been exclusively focusing on private homeowners, to subsidized homeowners. This study also adds to the literature on housing welfare by highlighting that the resale constraints of subsidized housing can weaken the housing wealth effect.
