We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...

The evolution of the ratio of direct taxation (characterized by progressive rates) over indirect and payroll taxation (characterized by flat rates) is examined together with its distributional consequences for the Bottom 50%, Middle 40% and Top 10% shares of income. Oscillations of this ratio...

A positive relationship between socio-economic status (SES) and health, the so-called "health-wealth gradient", is repeatedly found in most industrialized countries with similar levels of health care technology and economic welfare. This study analyzes causality from health to wealth (health...

We study inequality in the distribution of self-assessed health (SAH) in the United States and China, two large countries that have expanded their insurance provisions in recent decades, but that lack universal coverage and differ in other social determinants of health. Using comparable health...

How substantial are means-tested transfers in the United States? How have these transfers evolved over time, and what is their impact on the income distribution? We use microdata from the Survey of Income and Program Participation to document the scope of the main means-tested programs for...

Although the majority of research on US income inequality trends is based on public-use March CPS data, a new wave of research using IRS tax return data reports substantially higher levels of inequality and faster growing trends. We show that these apparently inconsistent estimates are largely...

This paper uses sequential stochastic dominance procedures to compare the joint distribution of health and income across space and time. It is the first application of which we are aware of methods to compare multidimensional distributions of income and health using procedures that are robust to...
