Inflation and the Accumulation of Assets in Private Pension Funds
This paper examines the effect of inflation on private pension saving. The role that private pensions can or should play in providing income in old age in the current inflationary environment is an important policy issue. A number of studies have discussed the effect of inflation on pensions. This study extends the existing analysis and presents the first empirical estimates. Inflation is seen to have a large negative effect on this aspect of retirement saving by workers.
Life-Cycle Welfare Costs of Social Security
One-period models predict that a substantial welfare gain would result from removing the Social Security earnings test. In this paper we show that such models overestimate the size of potential gains.
If one uses instead a two-period model, which captures intertemporal effects, the net result of removing the earnings test is ambiguous. In the presence of a personal income tax, workers who reduce their labor supply in the first period create a welfare loss that must also be considered. We use a present-value model to estimate the change in lifetime welfare. We find that the net potential gain from removing the earnings test is probably small, especially when compared with the alternative of an increased personal income tax.
