A Century of Growth and Improvement
指出现代增长模型通常忽略实际经济进步意味着生产和消费不同商品，而罗伯特·戈登的著作则聚焦于1870年以来美国生活水平的改善，强调新商品、服务及现有产品的改进对普通公民的意义。
The fact that actual economic advance over time normally means producing and consuming different things is usually left implicit in modern models of economic growth. By contrast, qualitative change--new goods and services, and better versions of what already existed--is central to Robert Gordon's history of the improvement of American living standards since 1870. A major contribution of his fine-grained account of this experience is to make clear what this improvement has meant, and why it has mattered to ordinary citizens.
