Challenges in quantitative economic analysis in support of multilateral trade negotiations
回顾乌拉圭回合前后农业贸易自由化的经济分析，指出定量研究在谈判后期相关性下降，并展望1999年新一轮谈判中需应对传统议题及环境、竞争政策等新挑战。
A wide range of economic analysis of agricultural trade liberalization was performed prior to and during the Uruguay Round of trade negotiations. Views differ as to the effectiveness of this research, although most would agree that it became less relevant as the negotiations progressed. This paper reviews the contributions of economists to the trade liberalization debate, with an emphasis on the quantitative assessment of multilateral agricultural trade liberalization. With a new round of agricultural trade negotiations scheduled to begin in 1999 it is crucial that the quantitative work required to support these negotiations begin in the near future. The authors conclude that the Uruguay Round outcome provides numerous challenges and opportunities in analyzing the traditional agenda of agricultural trade liberalization. In addition, new issues will be added to the agenda of the next round of negotiations. These include: trade and the environment, competition policy and intellectual property rights. It is important that economists begin to develop a research agenda that can address these issues and become activists in addressing these topics in public forums.
