本文研究了不完全竞争和非凸技术的经济均衡。跟随根岸的企业在向下倾斜的感知需求函数下实现利润最大化。根岸的假设，特别是假设一个单一的垄断竞争者在每个市场，是放松。在其他标准假设下，对于由凸技术和固定成本技术的结合在每个企业中定义的生产集，获得了均衡的存在性。根据一个反例，假定固定因素不同于可变因素。从技术上讲，证据在于定价规则。
The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi firms maximise profits under downward-sloping perceived demand functions. Negishi's assumptions, in particular the assumption of a single monopolistic competitor in each market, are relaxed. Existence of equilibria is obtained, under otherwise standard assumptions, for production sets defined in each firm by the union of a convex technology and a technology subjected to fixed costs. In the light of a counterexample it is assumed that fixed factors are distinct from variable factors. Technically the proof rests on pricing rules.
