Plenary paper 2:Between Scylla and Charibdys: Agricultural economists‘ navigation around protectionism and free trade
从三个角度分析农业经济学家对国内农业政策与全球市场相互依存的研究响应，包括自由化效应、保护主义根源、支持总量衡量及政策工具调整，并区分自由贸易者与实用主义者的立场，提出未来研究重点。
In connection with the tight interdependence between domestic agricultural policies and behaviour of world market and the present round of GATT negotiations, agricultural economists are increasingly being asked to produce significant pieces of research. This paper analyzes the supply responses of our profession from three different angles. First, recent research efforts by agricultural economists are surveyed with regard to the following areas: 1) effects of liberalization; 2) analyses of the roots and structure of agricultural protectionism; 3) the aggregate measure of support; 4) reinstrumentation. Second, starting from the analytical dichotomy between free-traders and pragmatists, recent developments in the international economics literature are surveyed, giving specific attention to the ‘new’ international economics and to the domestic and systemic dimensions of the political economy approach. Finally, on the basis of these surveys, a triad of doctrinal positions—hard free-traders; soft pragmatists; committed pragmatists—are specified and research issues of high future priority identified.
