This paper draws on Robert F. Engle's autoregressive conditionally heteroskedastic modeling strategy to formulate a conditional capital asset pricing model with time-varying risk and expected returns. The model is estimated by generalized method of moments. A capital asset pricing model that allows mean excess returns to shift in January survives generalized method of moments specification tests for a number of omitted variables. However, a residual dividend yield component is found to remain in the excess returns of smaller firms. The authors find significant monthly and quarterly components in the risk premia and beta estimates. Copyright 1991 by American Finance Association.
