Explains how we got into the current economic disaster that developed out of the economics and politics of the housing boom and bust. The "creative" financing of home mortgages and "creative" marketing of financial securities based on these mortgages to countries around the world, are part of the story of how a financial house of cards was built up--and then collapsed.

Between 1996 and 2006 the U.S. has experienced an unprecedented boom in house prices. As it has proven to be difficult to explain the large price increase by observable fundamentals, many observers have emphasized the role of speculation, i.e. expectations about future price developments. The argument is, however, often indirect: speculation is treated as a deviation from a benchmark. The present paper aims to identify house price expectation shocks directly. To that purpose, we estimate a VAR model for the U.S. and use sign restrictions to identify house price expectation, housing supply, housing demand, and mortgage rate shocks. House price expectation shocks are the most important driver of the boom and account for about 30 percent of the real house price increase. We also construct a model-based measure of exogenous changes in price expectations and show that this measure leads a survey-based measure of changes in house price expectations. Our main identification scheme leaves open whether expectation shifts are realistic or unrealistic. In extensions, we provide evidence that price expectation shifts during the boom were primarily unrealistic and were only marginally affected by realistic expectations about future fundamentals.

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.

Conventional wisdom held that housing prices couldn’t fall. But the spectacular boom and bust of the housing market during the first decade of the twenty-first century and millions of foreclosed homeowners have made it clear that housing is no different from any other asset in its ability to climb and crash. Housing and the Financial Crisis looks at what happened to prices and construction both during and after the housing boom in different parts of the American housing market, accounting for why certain areas experienced less volatility than others. It then examines the causes of the boom and bust, including the availability of credit, the perceived risk reduction due to the securitization of mortgages, and the increase in lending from foreign sources. Finally, it examines a range of policies that might address some of the sources of recent instability.

In this valuable resource, more than thirty of the world's top economists offer innovative policy ideas and insightful commentary on our most pressing economic issues, such as global warming, the global economy, government spending, Social Security, tax reform, real estate, and political and social policy, including an extensive look at the economics of capital punishment, welfare reform, and the recent presidential elections. Contributors are Nobel Prize winners, former presidential advisers, well-respected columnists, academics, and practitioners from across the political spectrum. Joseph E. Stiglitz takes a hard look at the high cost of the Iraq War; Nobel Laureates Kenneth Arrow, Thomas Schelling, and Stiglitz provide insight and advice on global warming; Paul Krugman demystifies Social Security; Bradford DeLong presents divergent views on the coming dollar crisis; Diana Farrell reconsiders the impact of U.S. offshoring; Michael J. Boskin distinguishes what is "sense" and what is "nonsense" in discussions of federal deficits and debt; and Ronald I. McKinnon points out the consequences of the deindustrialization of America. Additional essays question whether welfare reform was successful and explore the economic consequences of global warming and the rebuilding of New Orleans. They describe how a simple switch in auto insurance policy could benefit the environment; unravel the dangers of an unchecked housing bubble; and investigate the mishandling of the lending institutions Freddie Mac and Fannie Mae. Balancing empirical data with economic theory, The Economists' Voice proves that the unique perspective of the economist is a vital one for understanding today's world.
