Virtually all social science research related to obesity uses body mass index (BMI), usually calculated using self-reported values of weight and height, or clinical weight classifications based on BMI. Yet there is wide agreement in the medical literature that such measures are seriously flawed...

Beginning in 1983, and following the worst recession since the Great Depression, the United States experienced six years of uninterrupted economic growth, the longest such period since World War II. Along with this expansion came an increase in income inequality that many suggest diminished the...

We use a choice-based subsample of Social Security Disability Insurance applicants from the 1978 Social Security Survey of Disability and Work to test the importance of policy variables on the timing of application for disability insurance benefits following the onset of a work limiting health...

Perhaps the single greatest achievement of social policy in the United States over the last three decades has been reducing poverty in old age. The transition from work to retirement is no longer economically perilous for the vast majority of older American workers. For most married couples, the...

We propose a class of generalised percentile ratios as an alternative to the P90 / P10 ratio for measuring labour earnings inequality. We show that they are more robust to sampling the variation and rounding error prevalent in interview-based surveys, as demonstrated through a Monte Carlo...

We use monthly data from the Survey of Income and Program Participation and the Current Population Survey to estimate the effect of the minimum wage. Minimum wage increases significantly reduce the employment of the most vulnerable groups in the working-age population—young adults without a...

To measure income inequality with right censored (topcoded) data, we propose multiple imputation for censored observations using draws from Generalized Beta of the Second Kind distributions to provide partially synthetic datasets analyzed using complete data methods. Estimation and inference...

The March Current Population Survey (CPS) is the primary data source for estimation of levels and trends in labor earnings and income inequality in the USA. Time-inconsistency problems related to top coding in theses data have led many researchers to use the ratio of the 90th and 10th...
