International Leadership in Productivity at the Aggregate and Industry Level
分解各国人均GDP差异，发现美国在大部分经济领域是生产率领先者，行业层面的生产率差异比总体更大，欧洲国家缺乏行业领先地位，而德国存在结构效应。
Since many policies affect specific parts of economies differently, it is useful to decompose GDP per capita differences across countries into differences across smaller and smaller parts of economies. In this paper, we summarize recent contributions in this area and fit them together into a decomposition procedure for GDP per capita differences. The overall finding is that the U.S. is the productivity leader for the most of the economy. Moreover, international productivity differences at the aggregate level of the economies are in most cases translated into differences in the productivity of industries, at least compared to the productivity leader U.S. The variability of productivity differences at the industry level is, however, substantially higher than any differences at the aggregate or sector level. For the manufacturing sector alone the U.S. and Japan share the leadership on the industry level. In contrast, France, U.K., and Germany exhibit almost no leadership in productivity at the industry level. Hence, nation‐specific factors appear to be dominant in the comparison of European countries with the U.S. Finally, mix differences do not play a very large role for big countries. For Germany, however, the mix effect can help to reconcile relative high productivity for the market economy and lower productivity at disaggregated levels.
