The study looked at how housing market changes affect the economy in South Africa. By focusing on how people spend money on housing, the researchers found that housing market shocks can impact real output in the short term. These shocks mainly come from changes in housing demand, not money. About 20% of house price changes can be explained by these shocks. Overall, housing demand shocks can explain around 13% of changes in private spending and 14% of changes in the economy over the next 20 quarters.
