Two-Tier State Pensions: Labour Supply and Income Distribution

Abstract: This paper compares state pensions using a two-period model which allows for labor supply responses. A two-tier pension gives rise to a nonconvex budget constraint facing individuals, giving rise to a range of labor supply responses. The paper uses a social welfare function to consider the trade-off between average utility and inequality. The trade-off displays a backward bending section whereby, above a certain tax rate, further increases in tax reduce average utility and increase inequality. A major result is that, in terms of the trade-off between equity and efficiency, the flat-rate pension dominates the two-tier pension. Hence a higher social indifference curve can always be reached using a flat-rate pension. Copyright 1994 by Blackwell Publishers Ltd and The Victoria University of Manchester
