TESTING OLIGOPOLISTIC AND OLIGOPSONISTIC BEHAVIOUR: AN APPLICATION TO THE US MEAT‐PACKING INDUSTRY
扩展了产业组织中的推测方法，通过设定生产函数和联立方程模型，同时检验产品市场和要素市场的不完全竞争，并应用于美国肉类加工业，发现该行业在肉类和活畜市场均行使市场力量。
This paper extends the conjectural approach in industrial organisation to the analysis of imperfections in output and factor markets. Starting from the specification of a production function, the econometric analysis is based on the formulation and estimation of a simultaneous‐equation model consisting of a production function, first‐order conditions associated with factor employment, and two conjectural elasticities to parameterise the industry's oligopoly and oligopsony equilibria. As an example, we provide an application to the US meat‐packing industry. Our results suggest that the industry exercises market power in both the output (meat) market and the factor (live animal) market.
