This paper studies tax evasion at the top of the U.S. income distribution using IRS micro-data from (i) random audits, (ii) targeted enforcement activities, and (iii) operational audits. Drawing on this unique combination of data, we demonstrate empirically that random audits underestimate tax...

In 2008, the IRS initiated efforts to curb the use of offshore accounts to evade taxes. This paper uses administrative microdata to examine the impact of the enforcement efforts on taxpayers' reporting of offshore accounts and income. Enforcement caused approximately 60,000 individuals to...

We examine individual stock sales from 2008 to 2009 using population tax return data. The share of sales by the top 0.1 percent of income recipients and other top income groups rose sharply following the Lehman Brothers bankruptcy and remained elevated throughout the financial crisis. Sales by...

We investigate the response of small businesses operating as sole proprietorships to Form 1099-K, an information report released in 2011 which provides the Internal Revenue Service with information about payment card sales. Theory and distributional analysis isolates affected taxpayers, who...

We examine novel data on searches for capital-gains-tax-related information to determine when and how taxpayers acquire information. We find strong seasonal increases in information search around tax filing deadlines, suggesting that taxpayers seek information to comply with tax laws. Positive...

This paper uses account-level information, reported to the IRS by foreign financial institutions under the Foreign Account Tax Compliance Act (FATCA), to produce new evidence on the foreign financial wealth of U.S. households. We find that U.S. taxpayers hold around $4 trillion in foreign...

Empirical evidence suggests that individuals often evaluate options relative to a reference point, especially seeking to avoid losses. We undertake the first welfare analysis under reference-dependent preferences. We characterize the welfare impact of changes in reference points and prices,...

This paper analyzes consumption to evaluate the distributional effects of pension reforms. Using Swedish administrative data, we show that on average workers who retire earlier consume less while retired and experience larger drops in consumption around retirement. Interpreted via a theoretical...

How quickly does marginal utility fall with increasing consumption? It depends on the dimension along which we consider concavity of the utility function. This paper estimates the distribution of heterogeneous curvature parameters in individuals' utility functions from hypothetical choice data,...

We consider the optimal policy problem of a benevolent planner, who is uncertain about an individual's true preferences because of inconsistencies in revealed preferences across behavioral frames. We adapt theories of expected utility maximization and ambiguity aversion to characterize the...
