Acreage response in Pakistan: a co-integration approach
用协整和脉冲响应方法分析了巴基斯坦小麦、棉花、甘蔗和水稻的种植面积对价格冲击的反应，发现棉花、甘蔗和高产水稻反应显著，长期均衡约4年恢复。
This paper seeks to quantify the acreage responses of wheat, cotton, sugarcane and rice in Pakistan using co-integration techniques and impulse response analysis. Results indicate that acreages of wheat and basmati rice do not respond significantly to shocks in own-price while cotton, sugarcane and high yielding variety (HYV) rice do, and that long-run equilibrium is re-established after about 4 years. Irrigated area is an important determinant of acreage.
