A Nation of Gamblers: Real Estate Speculation and American History
比较了美国历史上多次房地产繁荣与衰退,发现每次泡沫中买家并非完全非理性,而是受限于认知能力,使用简单启发式模型,且低利率并非主因,低估违约风险才是推高价格的关键。
The great housing convulsion that buffeted America between 2000 and 2010 has historical precedents, from the frontier land boom of the 1790s to the skyscraper craze of the 1920s. But this time was different. There was far less real uncertainty about fundamental economic and geographic trends, making the convulsion even more puzzling. During historic and recent booms, sensible models could justify high prices on the basis of seemingly reasonable projections about stable or growing prices. The recurring error appears to be a failure to anticipate the impact that elastic supply will eventually have on prices, whether for cotton in Alabama in 1820 or land in Las Vegas in 2006. Buyers don't appear to be irrational but rather cognitively limited investors who work with simple heuristic models, instead of a comprehensive general equilibrium framework. Low interest rates rarely seem to drive price growth; underpriced default options are a more common contributor to high prices. The primary cost of booms has not typically been overbuilding, but rather the financial chaos that accompanies housing downturns.
