Tax burdens vary for firms of different sizes due to their variable tendency to seek exemptions or evade taxes.

This paper investigates the impacts of tax reforms implemented in Uganda in the mid-1990s on the prevalence of tax evasion and exemptions among firms, and their effects on the distribution and dispersion of tax burdens. Based on firm-level data collected from 243 firms, we observe that evasion and exemptions were widespread and that their prevalence actually increased during tax reforms. We use three-stage least squares to simultaneously estimate tax burdens, evasion and exemption patterns in 1995 and 1997. We find that tax exemptions benefit large businesses to a disproportionate degree, while evasion is more common among small businesses. This creates a situation in which medium-sized firms shoulder a disproportionate tax burden.

“The most important book on government policy that I’ve read in a long time.” —David Leonhardt, New York Times Even as they have become fabulously wealthy, the ultra-rich have seen their taxes collapse to levels last seen in the 1920s. Meanwhile, working-class Americans have been asked to pay more. The Triumph of Injustice presents a forensic investigation into this dramatic transformation, written by two economists who have revolutionized the study of inequality. Blending history and cutting-edge economic analysis, Emmanuel Saez and Gabriel Zucman offer a comprehensive view of America’s tax system alongside a visionary, democratic, and practical reinvention of taxes.

The Fund has long played a lead role in supporting developing countries’ efforts to improve their revenue mobilization. This paper draws on that experience to review issues and good practice, and to assess prospects in this key area.

This paper reviews the rapidly growing empirical literature on international tax avoidance by multinational corporations. It surveys evidence on main channels of corporate tax avoidance including transfer mispricing, international debt shifting, treaty shopping, tax deferral and corporate inversions. Moreover, it performs a meta analysis of the extensive literature that estimates the overall size of profit shifting. We find that the literature suggests that, on average, a 1 percentage-point lower corporate tax rate will expand before-tax income by 1 percent—an effect that is larger than reported as the consensus estimate in previous surveys and tends to be increasing over time. The literature on tax avoidance still has several unresolved puzzles and blind spots that require further research.

The Field of Public Economics has been changing rapidly in recent years, and the sixteen chapters contained in this Handbook survey many of the new developments. As a field, Public Economics is defined by its objectives rather than its techniques and much of what is new is the application of modern methods of economic theory and econometrics to problems that have been addressed by economists for over two hundred years. More generally, the discussion of public finance issues also involves elements of political science, finance and philosophy. These connections are evidence in several of the chapters that follow. Public Economics is the positive and normative study of government's effect on the economy. We attempt to explain why government behaves as it does, how its behavior influences the behavior of private firms and households, and what the welfare effects of such changes in behavior are. Following Musgrave (1959) one may imagine three purposes for government intervention in the economy: allocation, when market failure causes the private outcome to be Pareto inefficient, distribution, when the private market outcome leaves some individuals with unacceptably low shares in the fruits of the economy, and stabilization, when the private market outcome leaves some of the economy's resources underutilized. The recent trend in economic research has tended to emphasize the character of stabilization problems as problems of allocation in the labor market. The effects that government intervention can have on the allocation and distribution of an economy's resources are described in terms of efficiency and incidence effects. These are the primary measures used to evaluate the welfare effects of government policy.
