Do Private Pensions Increase National Saving?
NBER Working Paper No. 186 (Also Reprint No. r0029)
This paper discusses how private pension programs differ from public social security in their likely impact on aggregate saving. Although private pensions are likely to reduce direct saving by employees, this should be offset by the combination of companies' partial funding and the shareholders response to unfunded liabilities. In contrast to several earlier empirical studies that implied that social security does depress national saving, the current time series evidence suggests that the growth of private pensions has not had an adverse effect on saving and may have increased saving by a small amount.
