经验证据表明,许多产业具有外部规模经济的特征,但关于进入福利效应的文献却忽略了这一点。我们表明,在存在外部规模经济的情况下,进入可能是不足的,而不是过度的。通过一个具有特定需求和成本函数和古诺竞争的例子,我们证明了对于任何正的进入成本都会出现进入不足,并且进入不足的可能性随着进入成本的增加而增加。因此,在具有强大外部规模经济的行业中,反竞争进入监管可能是不合理的,这可能是由于知识溢出而产生的。
Empirical evidence suggests that many industries are characterized by external economies of scale, yet the literature on the welfare effects of entry has ignored this aspect. We show that entry can be insufficient instead of excessive in the presence of external economies of scale. Using an example with specific demand and cost functions and Cournot competition, we show that insufficient entry occurs for any positive cost of entry and the possibility of insufficient entry increases with a higher cost of entry. Hence, anti-competitive entry regulation may not be justified in industries with strong external economies of scale, which may occur due to knowledge spillover.
