摘要:Bonnen says that economic welfare is a function not only of the amount of goods and services available but also of their distribution. Mundlak develops a conceptual framework for analyzing the ways in which changes in the economic environment modify factor productivity, and focuses on the technology actually used in production (implemented technology) rather than the generation of technology. Botterill proposes a means for identifying the nature of the balance that is struck by governments between different values competing for support through agricultural policy settings, focuses on the different values that commonly arise in the development of agricultural policy, and suggests an approach which may clarify why different governments arrive at different policy settings in attempting to achieve an acceptable balance between competing interests.
