✦ Synopsis

The wew that the regzonal demand for fossd fuels by electric utlhtzes in the United States zs characterized by stable relationships ~s subjected to an objectwe statzst~cal test The test utd~zes a statzsttc whzch equals the ratio of the sum of squared residuals of one period predzctzon from the k + 1 perzod to the rth period to the sum of squared reszduals of one period predzctzon from the k + 1 to the Tth period, where k ts the number of estzmated coeffzclents m the model and T ~s the sample szze The results suggest, for the period 1973 1978, that the fosszl fuel demand functlons m Regzon H and Region VIII and the coal demand function zn Regzon X became unstable around 1977 For the other regions, the results mdzcate no appreczable (stattstzcally slgmfzcant) change ~n the relatwe zmportance of the underlying determinants of the demand for fossd fuels
