论文摘要
我们通过在小公司中引入成本异质性，将Parenti（2018）的模型扩展到大型和小型公司。我们为存在这种混合的市场结构提出了一种新颖的必要条件。此外，与Parenti（2018）相比，我们表明，在小公司之间存在成本异质性的情况下，贸易自由化可能会增加或减少运营中的小公司的质量。
We extend the model of Parenti (2018) on large and small firms by introducing cost heterogeneity among small firms. We propose a novel necessary and sufficient condition for the existence of such a mixed market structure. Furthermore, in contrast to Parenti (2018), we show that in the presence of cost heterogeneity among small firms, trade liberalization may raise or reduce the mass of small firms in operation.
