This paper reports on the results of a controlled experiment in Minnesota in which a random sample of taxpayers was informed that their income tax returns would certainly be closely examined. We analyze reported income of this sample of taxpayers, reported income on their previous year's...

For most parameter values, increased randomness about how much taxable income an auditor would assess leads to higher reported income and more revenue, When reducing randomness is costly, optimality requires some randomness in assessed taxable Income. Even if reducing randomness g costless,...

This paper reviews recent economic research in tax compliance and enforcement. After briefly laying out the economics of tax evasion, it focuses on recent empirical contributions. It first discusses what methodologies and data have facilitated these contributions, and then presents critical...

This paper shows that accounting for variation in mistakes can be crucial for welfare analysis. Focusing on consumer underreaction to not-fully-salient sales taxes, we show theoretically that the efficiency costs of taxation are amplified by differences in underreaction across individuals and...

This paper sets out a framework for analyzing optimal interventions by a tax administration, one that parallels and can be closely integrated with established frameworks for thinking about optimal tax policy. At its heart is a summary measure of the impact of administrative interventions--the...

Standard economic models of tax compliance have focused on enforcement-driven compliance. Notably, tax administrators also tend to place a great deal of emphasis on the importance of improving "tax morale" by encouraging voluntary compliance, creating a culture of compliance, and changing social...

Property taxes in developing countries are plagued by noncompliance and can exacerbate liquidity constraints. We characterize optimal enforcement and taxation policies as functions of revenue elasticities and measures of taxpayer hardship. We estimate these parameters using multiple sources of...

Are firms sophisticated maximizers, or do they consistently make errors? Using transaction-level data from Ugandan value-added tax (VAT) returns, we show that sellers and buyers report different amounts 79% of the time, despite invoices being easily cross-checked. We estimate that 25% of firms...

This paper studies the role of technology in local-government tax collection capacity in the developing world. We first conduct a new census of all local governments in Ghana to document a strong association between technology use and property tax billing, collection and enforcement. We then...
