Policy interactions in world grain markets
将小麦、玉米等粗粮贸易建模为动态博弈，允许跨市场政策互动，发现考虑跨商品效应时最优补贴与独立市场情形差异显著。
In this analysis, trade in wheat, corn, and other coarse grain markets is modelled as a dynamic game where policy interactions across markets are allowed. The world is decomposed into eight regions, six of which are active players in the game. Results indicate that, when across commodity market effects are explicitly incorporated, optimal subsidies are quite different from the standard independent market case.
