Housing And Commodity Investment Booms In A Small Open Economy

We add a housing sector to the Reserve Bank of Australia's small open-economy model to explore the effect of commodity price shocks on housing investment. The model predicts that housing investment booms may follow commodity booms. Commodity booms have a persistent effect on housing services price inflation and they 'crowd out' housing investment. When the commodity boom ends, the combination of higher prices and falling interest rates induces a significant housing investment response. The model attributes a significant share of the recent increase in housing investment in Australia directly to falling commodity prices.
