Dynamic Games and International Trade: An Application to the World Corn Market
用动态博弈分析国际玉米市场中买卖双方的市场力量，构建纳什非合作差分博弈模型，得出合理数值结果，为政策分析提供新工具。
Abstract Dynamic games are a conceptually useful way of analyzing imperfect markets where both buyers and sellers have potential market power. Previous analysis of imperfect markets was static and limited to either exporters or importers. A dynamic game allows the inclusion of both importers and exporters in a multiperiod framework allowing the derivation of reaction functions. A Nash noncooperative difference game is applied to the international corn market to explore the plausibility of numerical results. The results are reasonable and show that the game approach based on a more comprehensive econometric model has a promising future in policy analysis.
