英文文献：Innovation Activity In A Mixed Oligopoly: The Role Of Co-Operatives-混合寡头垄断下的创新活动:合作社的作用
英文文献作者：Giannakas, Konstantinos,Fulton, Murray E.
英文文献摘要：
This paper develops a sequential game theoretic model of heterogeneous producers to examine the effect of co-operative involvement on innovation activity in the agricultural input-supplying sector. Analytical results show that the co-operative involvement in R&D can be welfare enhancing and, thus, socially desirable. The presence of the co-op can increase the arrival rate of innovations and productivity growth while reducing the prices of agricultural inputs. The effectiveness of the co-op is determined by the size of R&D costs.
摘要本文建立了一个异质性生产者的序列博弈论模型，以考察合作参与对农业投入供给部门创新活动的影响。分析结果表明，研发中的合作参与可以提高福利，因此也是社会所希望的。合作社的存在可以提高创新和生产力增长的速度，同时降低农业投入的价格。合作的有效性取决于研发成本的大小。
