| The published empirical literature on frontier production functions is dominated by two broadly defined estimation approaches – parametric and non‐parametric. Using panel data on Korean rice production, parametric and non‐parametric production frontiers are estimated and compared with estimated productivity. The non‐parametric approach employs two alternative measures based on the Malmquist index and the Luenberger indicator, while the parametric approach is closely related to the time‐variant efficiency model. Productivity measures differ considerably between these approaches. It is discovered that measures of efficiency change are more sensitive to the choice of the model than are measures of technical change. Both approaches reveal that the main sources... |

| From the perspective of the food system, the overall food manufacturing or processing industry is fundamentally connected both with agricultural production in rural areas and consumption demand usually concentrated in urban areas. Using the local government level and individual firm level data for the food manufacturing industry in Korea, this paper investigated the agglomeration and spillover effects in this industry. This study found that there exist significant productivity differentials over space in food processing industry. This paper also found the evidences of agglomeration economies; the place where the size of population is large performs better. The results showed some evidences of spillover effects; negative externalities from congestions of... |
