An Alternative Theory of the Plant Size Distribution, with Geography and Intra- and International Trade
提出工厂规模分布的新理论，认为大厂生产标准化产品、小厂生产定制产品，并用美国机密普查数据验证模型，成功预测了中国进口冲击对工厂规模的影响。
There is wide variation in the sizes of manufacturing plants, even within the most narrowly defined industry classifications. Standard theories attribute such size differences to productivity differences. This paper develops an alternative theory in which industries are made up of large plants producing standardized goods and small plants making custom or specialty goods. It uses confidential census data to estimate the parameters of the model. The model fits the data well. In particular, the predictions of the model regarding the effect of a surge of imports from China are consistent with what happened over the period 1997-2007.
