We investigate the impact of the Social Security Annual Earnings Test (AET) on the employment decisions of older Americans. The AET reduces Social Security benefits by one dollar for every two dollars earned above the exempt amount. Using a differences-in-differences design, we find that the...

This paper provides an overview of an economics-based perspective on the financial aspects of state and local public pensions in the U.S. Drawing on the research commissioned for an NBER research program on this topic, we discuss the large degree to which public pension liabilities exceed the...

Building on the existing literature that examines the extent of redistribution in the Social Security system as a whole, this paper focuses more specifically on how Social Security affects the poor. This question is important because a Social Security program that reduces overall inequality by...

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...

We develop a method for estimating the effect of a kinked or notched budget set on workers' employment decisions, and we use it to estimate the impact of the Social Security Old-Age and Survivors Insurance (OASI) Annual Earnings Test (AET). The AET reduces OASI claimants' current OASI benefits...

This paper provides evidence on the investment behavior of 27 state pension plans that manage their own equity portfolios. Even though these state plans typically hold broadly diversified portfolios, they substantially over-weight the equity of companies that are headquartered in-state. The...
