In this paper the cost of capital of the UK's newly privatized utilities is estimated using both the CAPM and the APT. It is found that the APT provides a better description of excess security returns than the CAPM. However, neither model can explain the crosssection of excess returns on the...

We test the robustness of the APT to two alternative estimation procedures: the Fama and MacBeth (1973) two-step methodology; and the one-step procedure due to Burmeister and McElroy (1988). We find that the APT is indeed sensitive to the chosen estimator and assumptions about the factor...

In this paper we test the robustness of the CAPM to two alternative estimation procedures: the Fama and MacBeth (1973) two-step methodology; and the one-step methodology due to Burmeister and McElroy (1988). For the UK stock market we find that we can clearly reject the CAPM when the two-step...

Within a broad sample of US manufacturing firms, we find that, controlling for investment opportunities and financial constraints, increased governance quality is associated with higher levels of investment. Increased governance quality is also associated with greater responsiveness of...

The output gap, a production based macroeconomic variable, is a strong predictor of stock and bond returns. It is a prime business cycle indicator that does not include the level of market prices, thus removing any suspicion that returns are forecastable due to a fad in prices being washed away....
