We provide empirical evidence that the removal of work disincentives embedded in retirement earnings tests can increase old-age labor supply considerably, but it does so at the cost of more income inequality. To identify causal effects, we exploit a reform of the Norwegian early retirement program, which entailed that adjacent birth cohorts faced completely different work incentives from the age of 62. The reform removed a strict retirement earnings test such that pension wealth was redistributed from early to late retirees. Given pre-existing employment and earnings patterns, this implied a considerable rise in old-age income inequality. In theory, this direct increase in inequality could be either amplified or offset by changes in labor supply. We estimate that the reform triggered a 42% increase in average hours worked during the period covered by early retirement options; however, as labor supply responses were of similar magnitudes across the earnings distribution, they did little to modify the rise in inequality. As measured by the Gini coefficient, inequality in overall old-age income rose by approximately 0.03 (21%).
