Oligopolistic Market Structure in the Korean Beef Import Market

The United States and Australia are two major beef exporters to South Korea. This study primarily aims to determine the oligopolistic market structure in the Korean beef import market. Considering two different strategic variables in the oligopolistic market, quantity and price, six oligopolistic competition models were estimated. To select among the six models, various model fit indices and normalized likelihood ratio statistics were used. For other cuts with bone in of the fresh or chilled beef, the model that best fit the data was the Stackelberg model with US quantity leadership. But, for boneless of the fresh or chilled beef, other cuts with bone in of the frozen beef, and boneless of the frozen beef, the model that best fit the data was the Stackelberg model with Australia quantity leadership. Overall, this study shows that the quantity models fit the data better than price models to explain the oligopolistic market structure in the Korean beef import market.
