We study the marginal tax rate incorporated into short-term tax-exempt municipal rates using a unique new data set from the municipal swap market. By applying an affine term-structure framework, we are able to identify both the marginal tax rate and the credit/liquidity spread in one-week...

We study the optimal recursive refinancing problem where a borrower minimizes his lifetime mortgage costs by repeatedly refinancing when rates drop sufficiently. Key factors affecting the optimal decision are the cost of refinancing and the possibility that the mortgagor may have to refinance at...

We examine whether there is a flight-to-liquidity premium in Treasury bond prices by comparing them with prices of bonds issued by Refcorp, a U.S. Government agency, which are guaranteed by the Treasury. We find a large liquidity premium in Treasury bonds, which can be more than fifteen percent...

It is widely believed that Treasuries trade at premium prices because of their safety and money-like properties. In reality, this is only true on a relative basis when compared to other bonds, but is often not true on an absolute basis. Many Treasuries have repeatedly traded at substantial...

We identify a significant premium in the prices of Treasury floating rate notes (FRNs) relative to both Treasury bills and notes. This premium is directly related to the near-constant nature of FRN prices and differs from the liquidity and on-the-run premia in Treasury security prices previously...

We use the prices of credit card asset-backed securities to study the market risk premium associated with unsecured consumer credit risk. The consumer credit risk premium has historically been comparable to high yield corporate bond spreads, but has increased dramatically since the financial...

We present a new approach for estimating private equity returns using secondary market prices for entrepreneurial business credit card securitizations. We show that the market requires a significantly higher premium for entrepreneurial credit risk than for household credit risk. Entrepreneurial...

We show that the price of a Treasury bond and an inflation-swapped TIPS issue exactly replicating the cash flows of the Treasury bond can differ by more than $20 per $100 notional. Treasury bonds are almost always overvalued relative to TIPS. Total TIPS-Treasury mispricing has exceeded $56...

We study corporate bond default rates using an extensive new data set spanning the 1866-2008 period. We find that the corporate bond market has repeatedly suffered clustered default events much worse than those experienced during the Great Depression. For example, during the railroad crisis of...

How does the market value complex structured-credit securities? This issue is central to understanding the current financial crisis and identifying effective policy measures. We study this issue from a novel perspective by contrasting the valuation of CDO equity with that of bank stocks. This is...
