Details

Under the life-cycle savings hypothesis as developed by Franco Modigliani, the savings ratio (aggregate personal saving divided by disposable income) is explained by per-capita disposable income, the percentage rate of change in per-capita disposable income, and two demographic variables: the percentage of population less than 15 years old and the percentage of the population over 75 years old. The data are averaged over the decade 1960--1970 to remove the business cycle or other short-term fluctuations.

Format

[,1] sr numeric
aggregate personal savings [,2] pop15

pop75 numeric % of population over 75
[,4] dpi numeric
