This study presents an intriguing contrast of the ex ante and ex post relations between mortgage securitization and loan performance using a comprehensive dataset from a major national mortgage lender. While the paper supports that the bank applies lower screening efforts on loans that have higher ex ante probability of being securitized, it further shows that loans remaining on the bank’s balance sheet are, ex post, of worse quality than sold loans. Most of the delinquency difference can be explained by secondary market investors’ information advantage over the originating bank acquired over the time lag between loan origination and loan sale. While many blame the presence of the secondary market for creating demand for low-quality loans, we find that ironically these loans hurt the originating bank more than they did the secondary market.
