In the last boom, construction jobs expanded significantly, with investment in housing as a share of GDP increasing by 50% from 1997 to 2006. As my colleague Erik Hurst and his co-authors have shown, states that had the largest rise in construction as a share of GDP in 2000-2006 tended to have the greatest contraction in that industry in 2006-2009.
建筑就业在之前的繁荣期大幅增加，房地产投资的GDP占比从1997到2006年增长了50%。正如我的同事埃里克·赫斯特及其合作者所揭示的那样，2000－2006年间建筑就业GDP占比增长最快的州在2006－2009年收缩也最猛烈。这些州在2006－2009年失业率的变化也最剧烈。
