Generalised maximum entropy estimation and heterogeneous technologies
使用广义最大熵方法估计荷兰现金作物农场1970-1992年的面板数据，为每个农场估计投入需求和产出供给方程，捕捉技术异质性，并通过聚类分析识别技术相似的农场群。
Generalised maximum entropy methods are used to estimate a dual model of production on panel data of Dutch cash crop farms over the period 1970-1992. The generalised maximum entropy approach allows a coherent system of input demand and output supply equations to be estimated for each farm in the sample, thus capturing technological heterogeneity. The estimation results are used to perform a cluster analysis to identify groups of farms with similar technologies.
