ABSTRACT: There is widespread disagreement about the role of housing wealth in explaining
consumption. Much of the empirical literature is marred by poor controls for the common drivers
both of house prices and consumption, including income, income growth expectations, interest rates,
credit supply conditions, other assets and indicators of income uncertainty (such as changes in the
unemployment rate). For instance, while the easing of credit supply conditions is usually followed by
a house price boom, failure to control for the direct effect of credit liberalization on consumption can
over-estimate the effect of housing wealth or collateral on consumption. This paper suggests an
empirical model grounded in theory with more complete controls than hitherto used. It is applied to
modeling consumption in the UK and South Africa. Both countries experienced substantial credit
market liberalization and rising consumption to income ratios. However, South Africas
circumstances in the 1980s prevented an asset price boom, thus allowing the illumination of the direct
role of credit liberalization. The paper incorporates methodological improvements in the measurement
of credit conditions, and also clarifies the multi-faceted effects of credit liberalization on
consumption.
