Acreage response in Pakistan: a co‐integration approach
使用协整技术和脉冲响应分析，量化巴基斯坦小麦、棉花、甘蔗和水稻的种植面积对价格冲击的响应，发现棉花、甘蔗和高产水稻响应显著，而小麦和巴斯马蒂水稻不显著，长期均衡约4年恢复。
Abstract 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.
