This year, the NBER Macroeconomics Annual celebrates its thirtieth volume. The first two papers examine China’s macroeconomic development. “Trends and Cycles in China's Macroeconomy” by Chun Chang, Kaiji Chen, Daniel F. Waggoner, and Tao Zha outlines the key characteristics of growth and business cycles in China. “Demystifying the Chinese Housing Boom” by Hanming Fang, Quanlin Gu, Wei Xiong, and Li-An Zhou constructs a new house price index, showing that Chinese house prices have grown by ten percent per year over the past decade. The third paper, “External and Public Debt Crises” by Cristina Arellano, Andrew Atkeson, and Mark Wright, asks why there appear to be large differences across countries and subnational jurisdictions in the effect of rising public debts on economic outcomes. The fourth, “Networks and the Macroeconomy: An Empirical Exploration” by Daron Acemoglu, Ufuk Akcigit, and William Kerr, explains how the network structure of the US economy propagates the effect of gross output productivity shocks across upstream and downstream sectors. The fifth and sixth papers investigate the usefulness of surveys of household’s beliefs for understanding economic phenomena. “Expectations and Investment,” by Nicola Gennaioli, Yueran Ma, and Andrei Shleifer, demonstrates that a chief financial officer's expectations of a firm's future earnings growth is related to both the planned and actual future investment of that firm. “Declining Desire to Work and Downward Trends in Unemployment and Participation” by Regis Barnichon and Andrew Figura shows that an increasing number of prime-age Americans who are not in the labor force report no desire to work and that this decline accelerated during the second half of the 1990s.

World War I created a set of forces that affected the political arrangements and economies of all the countries involved. This period in global economic history between World War I and II offers rich material for studying international monetary and sovereign debt policies. Debt and Entanglements between the Wars focuses on the experiences of the United States, United Kingdom, four countries in the British Commonwealth (Australia, New Zealand, Canada, Newfoundland), France, Italy, Germany, and Japan, offering unique insights into how political and economic interests influenced alliances, defaults, and the unwinding of debts. The narratives presented show how the absence of effective international collaboration and resolution mechanisms inflicted damage on the global economy, with disastrous consequences.

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.

For dozens of developing countries, the financial upheavals of the 1980s have set back economic development by a decade or more. Poverty in those countries have intensified as they struggle under the burden of an enormous external debt. In 1988, more than six years after the onset of the crisis, almost all the debtor countries were still unable to borrow in the international capital markets on normal terms. Moreover, the world financial system has been disrupted by the prospect of widespread defaults on those debts. Because of the urgency of the present crisis, and because similar crises have recurred intermittently for at least 175 years, it is important to understand the fundamental features of the international macroeconomy and global financial markets that have contributed to this repeated instability. Developing Country Debt and the World Economy contains nontechnical versions of papers prepared under the auspices of the project on developing country debt, sponsored by the National Bureau of Economic Research. The project focuses on the middle-income developing countries, particularly those in Latin America and East Asia, although many lessons of the study should apply as well to other, poorer debtor countries. The contributors analyze the crisis from two perspectives, that of the international financial system as a whole and that of individual debtor countries. Studies of eight countries—Argentina, Bolivia, Brazil, Indonesia, Mexico, the Philippines, South Korea, and Turkey—explore the question of why some countries succumbed to serious financial crises while other did not. Each study was prepared by a team of two authors—a U.S.-based research and an economist from the country under study. An additional eight papers approach the problem of developing country debt from a global or "systemic" perspective. The topics they cover include the history of international sovereign lending and previous debt crises, the political factors that contribute to poor economic policies in many debtor nations, the role of commercial banks and the International Monetary Fund during the current crisis, the links between debt in developing countries and economic policies in the industrialized nations, and possible new approaches to the global management of the crisis.

An empirical investigation of financial crises during the last 800 years.

Since 1981 Latin America has been in the midst of a protracted external debt crisis due, among other reasons, to emergency borrowing at record-high real interest rates and the decline in the region's export proceeds. Until now, most literature on the subject originated in industrial lender countries, whose primary concern is the impact of the debt
