| Three trade policy changes underway and on the horizon have the prospect to alter global markets for japonica rice. This paper considers likely global market effects of expansion of access into the market in Japan and Korea, and reduced subsidy for japonica rice (among other crops) in the United States. We consider these policy changes in the context of a proposed Doha Development Agenda WTO agreement and one potential outcome of the proposed Free Trade Agreement between Korea and the United States (KUS-FTA). We use an equilibrium displacement model to ask how market prices, quantities and other aggregates change as a result of policy changes. The global model includes six aggregates in the world market, China, Korea, Japan, the United States, other... |

| 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... |

| This paper analyzes the rice production technology in Korea in the context of multi-output framework. The estimation uses a set of national farm-level panel data within the primal approach. The particular focus of the study is to analyze the existence of heterogeneous technologies for different farm sizes, and the possibility of output substitution. Unlike many previous studies, we employ a farm-specific fixed effects model, which accounts for the effects of individual specific characteristics or constraints on production. Our results suggest that considerable differences in technology exist across various farm sizes. Interestingly, input substitution and output substitution possibilities are more limited for smaller farms. However, in general, output... |
