Participation in Export Markets and Productivity of Plants in Los Angeles, 1987–1997
利用美国人口普查局未公开的工厂数据，研究洛杉矶地区工厂参与出口市场与生产率的关系，发现高生产率工厂更倾向于自我选择进入出口市场，而非通过出口学习提高效率。
Abstract This article investigates the relationship between the productivity of plants and participation in export markets in the greater Los Angeles area using unpublished plant‐level data from the U.S. Census Bureau's Longitudinal Research Database. Two key questions are examined: (1) do plants that export learn in foreign markets and become more efficient, or (2) do more efficient plants self‐select into export markets? The results support previous claims that more productive plants tend to self‐select into export markets. Little support is found for the learning‐by‐exporting argument. The policy implications of these findings are discussed.
