A Nonparametric Analysis of Agricultural Technology
用非参数方法分析美国农业技术和技术变革，基于1948-83年数据检验了总生产函数的可分离性假设，并揭示了技术变革的性质。
Abstract U.S. agricultural technology and technical change are analyzed nonparametrically under cost minimization and profit maximization. Based on annual data for 1948–83, various separability hypotheses concerning the aggregate production function for U.S. agriculture are investigated. The proposed nonparametric approach also provides some insights into the nature of technical change.
