This paper contains a statistical description of the whole U.S. forward rate curve (FRC), based on data from the period 1990-1996. We find that the average deviation of the FRC from the spot rate grows as the square- root of the maturity, with a proportionality constant which is comparable to...

Transitions to floating exchange rate regimes have led to sharp increases in exchange rate volatilities with no corresponding changes in the distribution of macroeconomic fundamentals. In the spirit of Dornbusch (1976), we assess whether nominal exchange rate overshooting is responsible for this...

Expected inflation is a major decision factor of various economic agents. Since expected inflation is not directly observable, economists have been seeking ways of extracting market’s inflation expectations from observable variables. One of the most reliable sources of inflation expectations...

This paper considers a class of Heath-Jarrow-Morton (1992) term structure models, characterized by time deterministic volatilities for the instantaneous forward rate. The bias that arises from using observed futures yields as a proxy for the unobserved instantaneous forward rate is analyzed. The...

Dynamic term structure models (DTSMs) price interest rate derivatives based on the model­ implied fair values of the yield curve, ignoring any pricing residuals on the yield curve that are either from model approximations or market imperfections. In contrast, option pricing in practice often...

We investigate whether the same finite dimensional dynamic system spans both interest rates (the yield curve) and interest rate options (the implied volatility surface). We find that the options market exhibits factors independent of the underlying yield curve. While three common factors are...

A careful examination of interest rate time series from different U.S. Treasury maturities by Wavelet Multiresolution Analysis (MRA) suggests that the first differences of the term structure of interest rate series are periodic or, at least, cyclic, non-stationary, long-term dependent, in...

Can scoring models help microfinance lenders in poor countries as much as they have helped credit-card lenders in rich countries? I model the probability that loans from a microlender in Bolivia had arrears of 15 days or more. Although arrears in microfinance depend on many factors difficult to...

This paper presents a scoring model that predicts the risk of drop-out for borrowers at a microfinance lender in Bolivia. Drop-out risk was greater for women, manufacturers, newer borrowers, and those with more arrears. Out-of-sample tests suggest that scoring may help microfinance lenders to...
