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 summaries of what has been learned. It discusses a promising new development—the analysis of randomized controlled trials mostly delivered via letters from the tax authority—and then reviews recent research using various methods about the impact of the principal enforcement tax policy instruments: audits, information reporting, and remittance regimes. I also explore several understudied issues worthy of more research attention. The paper closes by outlining a normative framework based on the behavioral response elasticities now being credibly estimated that allow one to assess whether a given enforcement intervention is worth doing.

The Tax Reform Act of 1986 constituted the most sweeping postwar change in the U.S. federal income tax. This paper considers what the Act accomplished and its implications for future tax policy. After a review of the Act itself, and why it happened, we consider the evidence of the Act's impact on economic activity and how this evidence squares with initial predictions. Where appropriate, we draw out how consideration of the impact of TRA86 has contributed to the development of the methodology of economic analysis. We conclude with an overall evaluation of the Act.

This paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data. First, we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis. We discuss what other parameters should be estimated when the elasticity is not a sufficient statistic. Second, we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the United States to illustrate those issues. Third, we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out. Finally, we discuss avenues for future research.

the 1970s there was no organized effort to keep Kiss, or other immigrant-headed bands such as Abba or the Village People, out of the United States.) In a similar fashion, pressure from U.S. farmers and other employers may account for why it is that each year 300,000 illegal immigrants succeed in entering and finding work in the United States (Passel, Capps, and Fix 2004). For any presidential administration, globalization is likely to be a tricky subject. The gains from international economic integration are spread among a diffuse group of consumers, while the losses are concentrated in specific industries and regions. Into the debate, economists can interject dispassionate analysis of the costs and benefits associated with cross-border flows of goods, capital, and labor. On immigration and trade, the ERP gets many things right, but it falters when discussing the distributional consequences of globalization. This may be driven in part by the report's predictable but still discomforting tendency to cheerlead for the president's policy proposals. In the end, we are left with a discussion of globalization's consequences that is less balanced and complete than one might have hoped. REFERENCES

The Journal of Economic Literature (JEL) regularly reviews books of interest to the economics profession. The Economic Report of the President (ERP) falls under that purview and beginning this year, the JEL will be reviewing the ERP. Toward that end, I have asked a handful of very prominent economists to review the 2005 ERP. Reviewers were chosen to reflect expertise on what I guessed would be key issues. Reviewers were given the following instructions: The ERP in principle should provide an accurate assessment of the consensus professional views of economists on any given issue, based on the research to date. Does the discussion in the ERP in fact accurately summarize what we as economists know? Reviewers were given free rein over what material they would review in the ERP but were urged to focus on their areas of particular expertise. In the reviews that follow, Joel Slemrod reviews the discussion of tax reform. Joe Farrell reviews the ERP's chapter titled “Innovation and the Information Economy.” Gordon Hanson reviews the chapters on international trade and on immigration. Robert Hall reviews the discussion of the adverse macroeconomic impact of rising oil prices while Jonathan Gruber reviews the ERP chapter titled “Expanding Individual Choice and Control.” Many thanks to the reviewers for the quick turnaround.
