This paper proposes a new family of specification tests and applies them to affine term structure models of the London Interbank Offered Rate (LIBOR)-swap curve. Contrary to Dai and Singleton (2000), the tests show that when standard estimation techniques are used, affine models do a poor job of...

If investors are myopic mean-variance optimizers, a stock's expected return is linearly related to its beta in the cross section. The slope of the relation is the cross-sectional price of risk, which should equal the expected equity premium. We use this simple observation to forecast the...

A number of variables are correlated with subsequent returns on the aggregate US stock market in the 20th Century. Some of these variables are stock market valuation ratios, others reflect patterns in corporate finance or the levels of short and long-term interest rates. Amit Goyal and Ivo Welch...

This paper proposes a new family of specification tests and applies them to affine term structure models of the LIBOR swap curve. Contrary to Dai and Singleton (2000), the tests show that affine models do a poor job modelling volatility at the short end of the term structure. Improving the...
