Understanding International Trade in Agricultural Products: One Hundred Years of Contributions by Agricultural Economists
回顾过去五十年农产品国际贸易研究的发展，从国内价格支持政策导致的农业混乱，到衡量政策扭曲、建模市场影响，并展望未来消费者偏好和气候变化对贸易的挑战。
Abstract The study of international trade in agricultural products has developed rapidly over the past fifty years. In the 1960s the disarray in world agriculture caused by domestic price support policies became the focus of analytical studies. There followed attempts to measure the distortions caused by policies also in developing countries and to model their impact on world agricultural markets. Tools were advanced to explain the trends and variations in world prices and the implications of market imperfections. Challenges for the future include analyzing trade based on consumer preferences for certain production methods and understanding the impact of climate change mitigation and adaptation on trade.
