The earnings test and the short-run work response to its elimination.

Eliminating the earnings test will have different effects on the work effort of persons aged 65-69, depending on whether or not they are currently working or currently receiving Social Security benefits. This article reviews the development of the earnings test and examines the theoretical implications on work effort of removing the test for members of this age group. It looks at the Current Population Survey (CPS) data to determine how many persons aged 65-69 have characteristics that can be identified with groups that would theoretically increase, decrease, or not change their work effort should they no longer be subject to the earnings test. This analysis suggests that at least 80 percent, and perhaps more than 90 percent, of the 9.7 million persons aged 65-69 will not change their level of work effort if the earnings test is eliminated. Individuals who would modify their hours worked and earnings are fairly evenly split among those who would increase, decrease, or have an undetermined direction of change in their work effort.
