We study associations among women's current marital status, past marital history, and later-life labor force participation. We first document these relationships using data from the 1986 to 2008 waves of the Survey of Income and Program Participation (SIPP). We then exploit variation in laws...

Reducing or eliminating Social Security's Retirement Earnings Test (RET) can encourage labor supply of older individuals receiving benefits. However, these reforms can encourage earlier claiming of Social Security benefits, permanently lowering future benefits. We explore the consequences, for...

Social Security faces a major financing shortfall. One policy option for addressing this shortfall would be to raise the earliest age at which individuals can claim their retirement benefits. A welfare analysis of such a policy change depends critically on how it affects living standards. This...

We construct a database of public pension policy changes with motivation and implementation information for ten OECD countries. Structural pension reforms, motivated by long-run sustainability concerns, often come with prolonged phase-in periods. In response to pension retrenchments implemented...

We estimate the impact of public pension systems on labor supply far from the normal retirement age by exploiting Poland's switch from a Defined Benefit to a Notional Defined Contribution scheme for men born after 1948. Using the universe of taxpayers and this sharp cohort-based discontinuity in...

This paper explains four methods of "price indexing" initial Social Security retirement benefits, and discusses the effect of each method on the fiscal sustainability of Social Security, benefit levels and replacement rates, redistribution, and sensitivity of system finances to demographic and...

This is the introduction to and summary of Phase III of an international research project to study the relationship between social security provisions and retirement. The project relies on the work of a large group of economists in 12 countries who conduct the analysis for each of their...

This paper begins by discussing the nature of and rationale for social insurance programs. I then consider three political principles and four economic principles that could guide the design and reform of social insurance programs. These ideas are then applied to unemployment insurance, Social...

Governments around the world have enacted or are currently considering fundamental structural reforms of their Social Security pension programs. The key feature in these reforms is a shift from a pure pay-as-you-go tax-financed system, in which taxes on current workers are primarily distributed...

Simulations are presented of the probability distributions of retirement incomes relative to the "benchmark" benefits specified in current law. Calculations of expected utility show that these risk reduction techniques can raise expected utility relative to the plans with no guarantees. The...
