Housing investment: What makes it so volatile? Theory and evidence from OECD countries

This paper explains how mortgage market liberalization can introduce greater volatility in the housing market, which is a stylized fact documented from OECD countries, with a DSGE model where households face a credit constraint and housing is used as collateral. The housing collateral constraint creates a link between the housing market and borrowing capacity, a link that amplifies the response of housing demand to technology shocks and strengthens in economies with more liberalized mortgage markets.
