We empirically investigate the benefits of multiple ratings not only at issuance of debt instruments but also during the subsequent monitoring phase. Using a record of monthly credit rating migration data on all U.S. residential mortgage-backed securities rated by Standard & Poor's, Moody's, and Fitch between 1985 and 2012 (154,600 tranches), our results provide empirical evidence that rating agencies put more effort in rating and outlook revisions when tranches have assigned multiple ratings. Furthermore, we see that in the case of multiple ratings, agencies do a better job in discriminating tranches with respect to default risk. On the downside, we observe a shift in collateral towards senior tranches and incentives for issuers to engage in rating shopping activities, but find no evidence that rating agencies exploit such behavior to attract more rating business. Our results contribute to the literature on information production of credit ratings and extend the perspective to the monitoring period after issuance.

When investors commit capital to a private equity fund, the money is not immediately invested but is called by the fund manager throughout an investment period of up to five years. The private equity business model allows fund managers to invest and divest the committed capital during the fund's lifetime at their own discretion, which gives them the flexibility to time the markets. Based on 7,591 private equity deals, which are benchmarked against 14,390 M&A transaction multiples, we find evidence that on average private equity funds are able to create value by timing the financial markets. Market timing ability is not captured by performance measures such as the PME, yet it is a potential source of returns for investors.
