   A multiple regression analysis was conducted to predict the future incomes from occupation and ages. The results of this analysis indicated that occupation and ages accounted for no significant amount of the record sales. R2=.08, F(2,310)=1.227,p>.05, indicating that occupation and ages do not influence future incomes.

    A second analysis was conducted to evaluate whether the present incomes and price level predicted future incomes. Present incomes accounted for a significant proportion of the future incomes, while price level accounted for a marginal significant proportion of the future incomes after controlling for the effects of occupation and ages. Rchange=.056, F(4,308)=5.273, p<.01. These results suggested that people who have high incomes at present are more likely to get higher incomes in the future with the lower price level.
