This paper analytically and empirically investigates the sensitivity of the return measurement interval to the market beta estimate and suggests a market beta estimation method incorporating the investment horizon through a vector autoregressive (VAR) model when there is serial correlation in...

This paper provides a Bayesian test of parameter non stationarity and an estimation procedure for the detection of change points in the time series of stock returns. The empirical results indicate that this procedure can identify the change points in the data without prior knowledge and provide...

The paper evaluates the ability of asset pricing models that do not use consumption data, and models that use consumption data as a proxy for true consumption, to explain the time-series and cross-sectional variation of expected returns of portfolios of stocks. Although some parameter...

I provide a risk-based rational explanation for the seasonal regularity of January in stock returns by suggesting a common risk factor related to the information uncertainty caused by earnings volatility. When the two-factor model with the market risk factor and this common risk factor is used,...

This paper examines the effect of commercial bank entry on underwriting spreads for IPOs, SEOs, and debt issues using a long time series that spans 30 years, from 1975 to 2004. We find that, on average, commercial banks charge lower spreads of approximately 72 basis points for IPOs, 43 basis...

To explain post-earnings announcement drift, we construct a risk factor related to unexpected earnings surprise, and propose a four-factor model by adding this risk factor to Fama and French's (1993), (1995) three-factor model. This earnings surprise risk factor provides a remarkable improvement...

Recent research has documented the failure of market beta to capture the cross-section of expected returns within the context of a two-pass estimation methodology. However, the two-pass methodology suffers from the errors-in-variables (EIV) problem that could attenuate the apparent significance...
