Relative U.K./U.S. Output Reconsidered: A Reply to Professor Broadberry
回应布罗德伯里教授对作者此前英美收入比较研究的批评，辩护其1870-1990年人均收入和人均产出估计的合理性。
In the September 2003 issue of this J OURNAL , we provided benchmark comparisons of U.K./U.S. income from 1870 to 1990. In contrast to long-span projections from Angus Maddison and others, our estimates show the United States leading from 1870 in terms of income per capita and output per worker. In a 12-page comment that accompanies our article, Professor Stephen Broadberry criticizes our work on three grounds. First, he charges our estimates are inconsistent with his U.K./U.S. sectoral productivity comparisons. Second, he chastises us on the grounds that our price benchmarks conflict with standard U.S. and U.K. price indices. Finally, he queries our nominal GDP estimates.
