AGGLOMERATION EXTERNALITIES, PRODUCTIVITY, AND TECHNICAL INEFFICIENCY*
研究了集聚外部性如何同时影响生产前沿和技术无效率，利用三文鱼养殖场面板数据发现集聚对两者均有正向效应。
ABSTRACT Agglomeration externalities can have positive effects on both the production possibility frontier and technical inefficiency of firms. Increased levels of localized knowledge spillovers and substitution of internal inputs with external inputs may lead to fewer errors in decision‐making and execution of production tasks, thus causing firms to become technically more efficient relative to the production frontier. When we estimate a stochastic frontier production model on a large panel of salmon aquaculture farms, we find econometric support for positive agglomeration externalities on both the production frontier and technical inefficiency.
