This paper studies the efficiency of financial intermediation through securitization with asymmetric information about the quality of securitized loans. In this theoretical model, I show that, in general, by providing reputation-based implicit recourse, the issuer of a loan can credibly signal its quality. However, in boom stages of the business cycle, information on loan quality remains private, and lower quality loans accumulate on balance sheets. This deepens a subsequent downturn. The longer the duration of a boom, the deeper will be the fall of output in a subsequent recession. In recessions, the model also produces amplification of adverse selection problems on re-sale markets for securitized loans. These are especially severe after a prolonged boom period and when securitized loans of high quality are no longer traded. Finally, the model suggests that excessive regulation that requires higher explicit risk-retention by the originators of loans can adversely affect both quantity and quality of investment in the economy.
