Korean livestock sector has been experiencing steady increas of real gross value of agricultural production despite its declining population over the last 30 years. It implies that Korean livestock sector has changed from labor-intensive to capital-intensive industry. In addition to this structural change, the acceleration of open market policies, especially completed and ongoing Free Trade Agreement (FTA) negotiations with major trading partners is likely to affect Korean livestock farm labor market significantly. This paper examines the impact that changing beef imports would have on beef farm labor demand using a partial equilibrium modeling system of Korean beef sector as well as farm labor demand for live cattle as a derived demand for beef demand. Beef farm labor demand is projected to decrease by 2.6% to 7.5% compared to baseline as beef imports increase 5%.
