Closing the gap between pre-retirement income and retirement income without increasing mandatory social security contributions for the working population has become a policy issue for many countries in the last couple of years. In order to incentivize people to save privately for retirement,...

In this paper, we explore the underlying explanations for the under financing of the U.S. Social Security pension system that has persisted since the late 1980s despite repeated calls for reform by the program's trustees and various advisory groups. Both micro and macro estimates of the cost...

Anticipating the labor market effects of welfare reforms is difficult due to public policy interactions across programs and among household members. Specifically, changes to one program may affect individual take-up of other programs, and individual participation in specific programs may...

Paul Samuelson made a series of important contributions to population theory for humans and other species, evolutionary theory, and the theory of age structured life cycles in economic equilibrium and growth. The work is highly abstract but much of it was intended to illuminate issues of...

The U.S. Social Security pension system is not adequately financed to fully meet benefit obligations specified in current law beyond the early 2030s. This potential financing shortfall has been recognized for at least the past quarter century but policymakers have done nothing to address it. The...

In an online experiment with more than 2,000 participants, we measure consistency of time preference and study actual and planned retirement timing decisions. Theory predicts that hyperbolic time preferences can lead to dynamically inconsistent retirement timing. We find that time inconsistent...

This study answers the open question of whether workers respond to financial incentives in a command economy. To do this, I evaluate pension reforms in Soviet Russia in 1964 and 1969 that allowed pensioners to receive a greater share of their pensions if they worked, resulting in a progressive...

Fertility has long been declining in industrialised countries and the existence of public pension systems is considered as one of the causes. This paper provides detailed evidence based on historical data on the mechanism by which a public pension system depresses fertility. Our theoretical...
