Welfare Impacts of Cross‐Country Spillovers in Agricultural Research
分析知识产权保护对私营农业研究福利的影响，考虑各国保护水平不同、技术跨国溢出及公共部门参与，建立模型确定受益方和成本承担方，并讨论政策协调的后果。
Abstract The welfare implications of intellectual property protection (IPP) for private sector agricultural research are analyzed, focusing on the realistic cases where countries provide different IPP levels, technology spills over across countries, and the public sector is involved in research. A model is developed to determine who benefits from, and who should pay for, the associated research. The article contains some interesting results on the implications of a harmonization of IPP policies through multilateral agreements or via technology that allows research firms to prevent the copying of plants and animals that express traits that have emerged from their research.
