Structural change in European calf markets: decoupling and the blue tongue disease
研究了欧盟农业政策改革和蓝舌病疫情如何共同影响四个主要欧盟成员国犊牛市场的价格空间依赖关系，发现市场一体化且价格冲击快速吸收，脱钩政策导致犊牛价格下降。
European cattle markets have recently undergone significant change. We explore the simultaneous impacts of agricultural policy reform and the occurrence of an animal health crisis on spatial interdependencies of calf prices of four major European Union markets. The markets are found to be integrated. Price shocks are rapidly absorbed. We find that the member state specific implementations of the 2003 Common Agricultural Policy reforms significantly affected prices of both the national market and of other member states. The blue tongue disease further induced structural change. Using counterfactual scenarios, we show that the decoupling of payments from production led to reduced calf prices.
