Public Pensions and Private Savings

How does the provision of public pension benefits impact private savings?

How does the provision of public pension benefits impact private savings? We answer this question in the context of a Danish reform that increased social security eligibility ages. Using administrative data and a regression discontinuity design, we identify the causal effects of the policy on savings throughout the financial portfolio. We find increases in contributions to personal and employer-sponsored retirement accounts when delayed benefit eligibility induces extended employment. We argue that inertia—the continuation of previous savings behaviors—is a key mechanism, and we highlight how firm default contribution rate policies can mediate savings responses to social security reform.
