The Rise of Non-Regulated Financial Intermediaries in the Housing Sector and its Macroeconomic Implications
I examine the impact of non-regulated lenders in the mortgage market using a dynamic stochastic general equilibrium (DSGE) model. My model features two types of financial intermediaries that differ in three ways: (i) only regulated intermediaries face a capital requirement, (ii) non-regulated intermediaries finance themselves by selling securities and cannot accept deposits, and (iii) non-regulated intermediaries face a more elastic demand. This last assumption is based on empirical evidence for Canada revealing that non-regulated intermediaries issue loans at a lower interest rate. My results suggest that the non-regulated sector contributes to stabilize the economy by providing an alternative source of capital when the regulated sector in unable to fulfill the demand for credit. As a result, an economy with a large non-regulated sector experiences a smaller downturn after an adverse financial shock.
