We examine whether and to what extent consolidation in the U.S. health insurance industry is leading to higher employer-sponsored insurance premiums. We make use of a proprietary, panel dataset of employer-sponsored healthplans enrolling over 10 million Americans annually between 1998 and 2006...

Implicit taxes in Social Security, which measure Social Security contributions net of benefits accrued as a percentage of earnings, tend to increase over the life cycle. In this paper, we examine the effects of three potential policy changes on implicit Social Security tax rates: extending the...

Social Security faces a major long-term funding crisis. A 38 or greater percentage increase in the systems' tax rate is needed to meet current benefit payments on an ongoing basis. Tax increases of this magnitude or comparable benefit cuts would significantly worsen what is already a very bad...

Uncertainty and its composition can affect the demand for social insurance, and thereby the labor market. This paper shows that small to medium-sized increases in uncertainty or risk aversion are enough to recommend an expansion of the safety net that would be broadly similar to the actual...

We extend previous estimates of the average marginal tax rate from the federal individual income tax to include social security "contributions." The social security tax is a flat-rate levy on labor earnings (and income from self-employment) up to a ceiling value of earnings. Our computations...

Evidence shows that people have difficulty understanding complex aspects of retirement planning, which leads them to under-utilize annuities and claim Social Security benefits earlier than is optimal. To target this problem, we developed vignettes about the consequences of different...

Recent advances in the examination of efficiency gains from dynamic tax reforms have used simulation models to isolate intragenerational and/or intergenerational effects. Important considerations having to do with uncertainty or capital market imperfections are frequently missing from such a...

We examine the connection between taxes paid and benefits accrued under the Social Security Disability Insurance (SSDI) program on both the intensive and extensive margins. We perform these calculations for stylized workers given the existing benefit structure and disability hazard rates. On the...
