Have the GSE affordable housing goals increased the supply of mortgage credit?

In the 1980s, housing market analysts and policymakers were concerned that Freddie Mac and Fannie Mae were not adequately facilitating the financing of affordable housing for low- and moderate-income families. To address these concerns, the Department of Housing and Urban Development established quantitative Affordable Housing Goals requiring the Government Sponsored Enterprises (GSEs) to increase their purchases of mortgages originated by low- and moderate-income households and for homes located in low-income neighborhoods. Our analysis indicates that the goals increased the supply of mortgage credit available to low- and moderate-income households, after controlling for other mortgage market factors. Our analysis suggests that the increase in the supply of low-income mortgage credit occurred primarily in 1998.
