This study addresses a fundamentally new feature of the contemporary world economy: the simultaneous buildup of very large public deficits and debt positions in virtually all of the advanced high-income countries. The recent global financial crisis sharply accelerated this fiscal deterioration, but it was already well underway in some countries, including the United States, where demographic prospects had posed extremely worrisome trajectories for a number of years. The book has three basic objectives. First, it projects the global fiscal outlook to 2035. Second, it asks whether the combination of deficits and debt in a large number of countries at the same time produces an impact on the world economy that is qualitatively different from the more traditional emergence of such problems in one or a few countries in any given period. Third, it analyzes the effects of the fiscal prospects on key economic variables including global interest rates and growth rates. The analysis finds that the current public debt profiles in most advanced economies will grow to dangerous and unsustainable levels over the next couple of decades unless major changes are made in projected spending and revenue levels. The authors conclude that the United States and Japan, in particular, need to start planning now for significant future budget cuts to minimize the risk of a crisis. Acting soon enables the adjustment to be phased in over an extended period, which cushions the inevitable adjustment costs, while avoiding the potentially enormous pressures that could be levied by markets if correction is delayed too long.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

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.

This paper describes the compilation of the Global Debt Database (GDD), a cutting-edge dataset covering private and public debt for virtually the entire world (190 countries) dating back to the 1950s. The GDD is the result of a multiyear investigative process that started with the October 2016 Fiscal Monitor, which pioneered the expansion of private debt series to a global sample. It differs from existing datasets in three major ways. First, it takes a fundamentally new approach to compiling historical data. Where most debt datasets either provide long series with a narrow and changing definition of debt or comprehensive debt concepts over a short period, the GDD adopts a multidimensional approach by offering multiple debt series with different coverages, thus ensuring consistency across time. Second, it more than doubles the cross-sectional dimension of existing private debt datasets. Finally, the integrity of the data has been checked through bilateral consultations with officials and IMF country desks of all countries in the sample, setting a higher data quality standard.

Volatile exchange rates and how to manage them are a contentious topic whenever economic policymakers gather in international meetings. This book examines the broad parameters of exchange rate policy in light of both high-powered theory and real-world experience. What are the costs and benefits of flexible versus fixed exchange rates? How much of a role should the exchange rate play in monetary policy? Why don't volatile exchange rates destabilize inflation and output? The principal finding of this book is that using monetary policy to fight exchange rate volatility, including through the adoption of a fixed exchange rate regime, leads to greater volatility of employment, output, and inflation. In other words, the "cure" for exchange rate volatility is worse than the disease. This finding is demonstrated in economic models, in historical case studies, and in statistical analysis of the data. The book devotes considerable attention to understanding the reasons why volatile exchange rates do not destabilize inflation and output. The book concludes that many countries would benefit from allowing greater flexibility of their exchange rates in order to target monetary policy at stabilization of their domestic economies. Few, if any, countries would benefit from a move in the opposite direction.

This paper explores the impact of high public debt on long-run economic growth. The analysis, based on a panel of advanced and emerging economies over almost four decades, takes into account a broad range of determinants of growth as well as various estimation issues including reverse causality and endogeneity. In addition, threshold effects, nonlinearities, and differences between advanced and emerging market economies are examined. The empirical results suggest an inverse relationship between initial debt and subsequent growth, controlling for other determinants of growth: on average, a 10 percentage point increase in the initial debt-to-GDP ratio is associated with a slowdown in annual real per capita GDP growth of around 0.2 percentage points per year, with the impact being somewhat smaller in advanced economies. There is some evidence of nonlinearity with higher levels of initial debt having a proportionately larger negative effect on subsequent growth. Analysis of the components of growth suggests that the adverse effect largely reflects a slowdown in labor productivity growth mainly due to reduced investment and slower growth of capital stock.

The world economy is experiencing a very strong but uneven recovery, with many emerging market and developing economies facing obstacles to vaccination. The global outlook remains uncertain, with major risks around the path of the pandemic and the possibility of financial stress amid large debt loads. Policy makers face a difficult balancing act as they seek to nurture the recovery while safeguarding price stability and fiscal sustainability. A comprehensive set of policies will be required to promote a strong recovery that mitigates inequality and enhances environmental sustainability, ultimately putting economies on a path of green, resilient, and inclusive development. Prominent among the necessary policies are efforts to lower trade costs so that trade can once again become a robust engine of growth. This year marks the 30th anniversary of the Global Economic Prospects. The Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.
