This paper models complexity in social programs as a byproduct of efforts to screen between deserving and undeserving applicants. While a more rigorous screening technology may have desirable effects on targeting efficiency, the associated complexity introduces transaction costs into the...

In this paper, we examine the effect of observed and unobserved heterogeneity in the desire to die with positive net worth. Using a structural life-cycle model nested in a switching regression with unknown sample separation, we find that roughly three-fourths of the elderly single population has...

Business income constitutes a large and increasing share of income and wealth at the top of the distribution. We discuss how tax policy treats and shapes how businesses are organized and how they distribute economic gains to owners, with the focus on closely-held and pass-through firms. These...

We use Norwegian administrative data and applications for emergency government support to simulate magnitude and distribution of business revenue shock due to the Covid-19 pandemic. We rely on it to analyze the impact of business support policies available in Norway and the United States by...

Business income is important in the upper tail of the personal income distribution, but the extent to which it is captured by measures of personal income varies substantially across tax regimes. Using linked individual and firm data from Norway, we are able to attribute business income to...

We study wealth inequality in childhood using Danish wealth records from three decades. While teenagers have some earnings, we estimate that transfers account for at least 50 percent of wealth at age 18, and much more so for the rich children. Inheritance from grandparents does not appear...

I discuss available evidence about the evolution of top wealth shares in the United States over the last one hundred years. The three main approaches – Survey of Consumer Finances, estate tax multiplier techniques and capitalization method – generate generally consistent findings until...

Tax reforms usually change both tax rates and tax bases. Using a panel of income tax returns spanning the two major U.S. tax reforms of the 1980s and a number of smaller tax law changes, I find that the elasticity of income reported on personal income tax returns depends on the available...
