Intercountry Life-Cycle Savings Data

#### Description

Data on the savings ratio 1960–1970.

#### Format

`country`

Name of the country.

`sr`

Aggregate personal savings.

`pop15`

Percentage of population under 15.

`pop75`

Percentage of population over 75.

`dpi`

Real per-capita disposable income.

`ddpi`

Percent growth rate of dpi.

#### 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.

#### Source

The data were obtained from Belsley, Kuh and Welsch (1980). They in turn obtained the data from Sterling (1977).
