Based on the findings of a commission chaired by James Mirrlees, this volume presents a coherent picture of tax reform whose aim is to identify the characteristics of a good tax system for any open developed economy, assess the extent to which the UK tax system conforms to these ideals, and recommend how it might be reformed in that direction.

No government can be sustained without the ability to tax its citizens. The question then arises how can a nation do so in a way that's fair and equitable to taxpayers while simultaneously promoting economic growth and providing the state with the funds it needs to adequately address the needs of its citizens? This insightful work, featuring contributions from a stellar array of international tax experts and economists, addresses the crucial, relevant issues which developed countries will confront in the early decades of the 21st century: The pursuit of tax reform. Personal tax base: income or consumption? Tax rate scale: equity and efficiency aspects. Business tax reform: structural and design issues. Interjurisdictional issues. Controlling tax avoidance.

What are the grand dynamics that drive the accumulation and distribution of capital? Questions about the long-term evolution of inequality, the concentration of wealth, and the prospects for economic growth lie at the heart of political economy. But satisfactory answers have been hard to find for lack of adequate data and clear guiding theories. In this work the author analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. His findings transform debate and set the agenda for the next generation of thought about wealth and inequality. He shows that modern economic growth and the diffusion of knowledge have allowed us to avoid inequalities on the apocalyptic scale predicted by Karl Marx. But we have not modified the deep structures of capital and inequality as much as we thought in the optimistic decades following World War II. The main driver of inequality--the tendency of returns on capital to exceed the rate of economic growth--today threatens to generate extreme inequalities that stir discontent and undermine democratic values if political action is not taken. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, the author says, and may do so again. This original work reorients our understanding of economic history and confronts us with sobering lessons for today.

This paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.

This paper addresses core challenges that all tax administrations face in dealing with noncompliance—which are now receiving renewed attention. Long a priority in developing countries, assuring strong compliance has acquired greater priority in countries facing intensified revenue needs, and is critical for fairness and statebuilding.
