PRODUCTION ANALYSIS: A NON‐PARAMETRIC TIME SERIES APPLICATION TO US AGRICULTURE
提出一种非参数方法，在数据不完全符合利润最大化假设时，利用“有效投入与产出”概念评估技术和经济行为，并应用于美国农业时间序列数据，测度生产率增长和技术变化偏向。
The paper investigates production analysis using non‐parametric methods. When all data are not consistent with profit maximisation, we propose a method relying on the concept of ‘effective inputs and outputs’ to evaluate technology and economic behaviour. The approach is illustrated in a time series application to US agriculture. The results provide empirical measures of productivity growth. They also generate useful information on the ‘bias in technical change’ in US agriculture.
