Market Power of Domestic Marketers and its Influence on the Consequences of the Korea--US and Korea--Australia FTAs on the Beef Market

Domestic, US and Australian beef, which are differentiated by country of origin, are sold in Korea. In this differentiated product market, tariff reductions through Free Trade Agreements (FTAs) are expected to strengthen the competitiveness of imported beef and, therefore, to mitigate the effects arising from the market power of domestic marketers. The present study develops a simulation model that evaluates this mitigating effect by explicitly reflecting the market structure that domestic beef marketers constitute. The simulation results indicate that the farm-retail marketing margin would decrease by 10.59% or 6.79% due to the Korea--US and Korea--Australia FTAs, respectively, if domestic beef marketers formed a cartel or an oligopoly market (i.e. the degree of market power is 0.5), while the marketing margin under a competitive market scenario is simulated to have no change. The value of beef production would decrease by 1009 million dollars if the marketers form a cartel and hence exercise monopoly power. The FTAs are simulated to reduce the value of beef production by 564 million dollars under the competitive market scenario.
