A Cross-Country, Cross-Industry Comparison of Productivity Growth
比较了六个国家五个主要行业的生产率增长，发现生产率增长在同一国家内跨行业的相关性高于同一行业跨国间的相关性，且国家特定因素解释了年度生产率变化的大部分。
This paper presents evidence on the nature of productivity growth for five major industries in six countries. Outp ut growth is found to be more correlated across countries than productivity growth. In addition, productivity growth is more correlated across industries within one country than across countrie s within one industry. Using an error-components model, the paper find s that a substantial fraction of changes in annual productivity can be attributed to nation-specific factors that are common across industries. The evidence suggests that short-run productivity growth is similar across industries in a nation but less similar across countr ies in any specific industry.
