Tax enforcement may affect both the behavior of those directly treated and of some taxpayers not directly treated but linked via a network to those who are treated. A large-scale randomized field experiment enables us to examine both the direct and network effects of letters and in-person visits...

According to the canonical model of Allingham and Sandmo (1972), firms evade taxes by making a trade-off between a lower tax burden and higher expected penalties. However, there is still no consensus about whether real-world firms operate in this rational way. We conducted a large-scale field...

In 2005, over 8% of Norwegian shareholders transferred their shares to new (legal) tax shelters intended to defer taxation of capital gains and dividends that would otherwise be taxable in the aftermath of 2006 reform. Using detailed administrative data we identify family networks and describe...

find strong evidence that strategic misreporting was present but conclude that its remaining quantitative extent after enforcement actions already taken by the tax authorities was relatively small. Firms tend to misreport 4 percent more often than expected, and the actual support paid out was 5...

This article surveys the theory of the public enforcement of law -- the use of public agents (inspectors, tax auditors, police, prosecutors) to detect and to sanction violators of legal rules. We first present the basic elements of the theory, focusing on the probability of imposition of...

Regulators often rely on self-reported data to determine compliance. Tolerance for missingness in self-monitoring data may create incentives for local agents to strategically decide when (not) to monitor regulated activities. This paper builds a framework to detect whether local governments skip...

We analyze the history of Japanese foreign exchange interventions from 1971 to 2018. First, we provide the best proxy for monthly interventions for the period from 1971 to 1990, when the intervention timings and amounts were not officially disclosed. The accuracy of the proxy is tested for the...

We estimate the impact of state-level "E-Verify" legislation that mandates employment eligibility verification for private-sector workers. We document declines in formal sector employment and employment turnover after mandate passage, with effects concentrated among those likeliest to be...

How should recipients of publicly-provided goods and services prove their identity in order to access these benefits? The core design challenge is managing the tradeoff between Type-II errors of inclusion (including corruption) against Type-I errors of exclusion whereby legitimate beneficiaries...
