In response to the global financial crisis, governments provided substantial support to the financial and other key sectors. Although this cushioned the adverse effects of the crisis, it is necessary now to articulate a strategy to ensure the sustainability of public finances. This paper discusses the scale and composition of fiscal adjustment that will need to occur once the recovery is securely under way. Although specific country-level circumstances will influence the composition of the adjustment and its political feasibility, in many cases restoring fiscal sustainability will require reforms to reduce spending and increase tax revenue.

Prominent economists reconsider the fundamentals of economic policy for a post-crisis world. In 2011, the International Monetary Fund invited prominent economists and economic policymakers to consider the brave new world of the post-crisis global economy. The result is a book that captures the state of macroeconomic thinking at a transformational moment. The crisis and the weak recovery that has followed raise fundamental questions concerning macroeconomics and economic policy. These top economists discuss future directions for monetary policy, fiscal policy, financial regulation, capital-account management, growth strategies, the international monetary system, and the economic models that should underpin thinking about critical policy choices.

This paper identifies policy tools that could be used for fiscal consolidation in advanced and emerging economies in the years ahead. The consolidation strategy, particularly in advanced countries, should aim to stabilize age-related spending in relation to GDP, reduce non-age-related expenditure ratios, and increase revenues. Bold reforms are needed to offset projected increases in age-related spending, particularly health care. On the revenue side, measures could include improving tax compliance, for example through better international cooperation, as well as increasing the yield from VAT by eliminating exemptions and reduced rates, further developing property taxes, and increasing excise rates within the range of rates already applicable in comparable countries.

The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

The volume provides a comprehensive overview of the financial and economic crises of 2008-2009 and the economic and financial policy implications for growth in developing countries.
