The primary such cost is the distortion in private saving. The present paper derives the level of Social Security benefits that is optimal in three basic cases. In the first section of the paper, the optimal level of benefits is derived for an economy in which all individuals do not anticipate retirement at all and therefore do not save. The second and third sections then derive the optimal benefits for economies with two different definitions of attitudes toward retirement and saving. ER -
