The Enduring Impact of the American Dust Bowl: Short- and Long-Run Adjustments to Environmental Catastrophe
研究了1930年代美国沙尘暴对农业土地价值和收入的长期负面影响，发现农业调整仅弥补了不到25%的初始损失，而人口大幅下降是主要调整方式。
The 1930s American Dust Bowl was an environmental catastrophe that greatly eroded sections of the Plains. The Dust Bowl is estimated to have immediately, substantially, and persistently reduced agricultural land values and revenues in more-eroded counties relative to less-eroded counties. During the Depression and through at least the 1950s, there was limited relative adjustment of farmland away from activities that became relatively less productive in more-eroded areas. Agricultural adjustments recovered less than 25 percent of the initial difference in agricultural costs for more-eroded counties. The economy adjusted predominantly through large relative population declines in more-eroded counties, both during the 1930s and through the 1950s.
