This article is based on a master's thesis in financial economics. The
author investigates whether the returns on the Finnish stock market a
re forecastable, by studying the time variations in the risk premia in
an ATP-model for the period 1976-1990. The results presented in this
article show, however, that the returns are for the most part not fore
castable with the aid of macroeconomic variables observable at the beg
inning of the return period.
