TIME VARYING RISK PREMIUM AND THE PREDICTIVE POWER OF THE AUSTRALIAN TERM STRUCTURE OF INTEREST RATES

Using weekly data on bank accepted bills over the 1976 to 1993 period, this paper provides direct evidence of the presence of a term premium in the Australian term structure. The term premium is shown to vary over time and have an adverse effect on the predictive power of the term structure. The variance of the expected term premium is quantified in terms of its lower bound relative to the upper bound of the variance of the rational expectations error. This ratio is observed to vary over sample sub periods and rise to a high of one in some periods which include the period immediately prior to the market crash.
