An immediate issue that arises, as discussed by Engle and GonzaÂlez-Rivera (1991) is that the quasi-maximum likelihood estimator (QMLE) may be inecient when the conditional density function is skewed.
Many authors following Engle have allowed for conditional distributions other than the normal to be used. The most common of these alternative distributions are the Student's t-distribution (Bollerslev, 1987) and the generalized error density (Nelson, 1991). The use of asymmetric density functions in ARCH models has been more limited. Early attempts to capture asymmetry include Hsieh (1989) and Gallant, Hsieh and Tauchen (1991). Review of asymmetric conditional density functions 27 Engle and GonzaÂlez-Rivera (1991) also found evidence of asymmetry in their semi-non-parametric model of individual stock returns and foreign exchange rates.
