Production interrelationships and productivity measurement in Irish agriculture
利用广义超越对数成本函数模型，测量了爱尔兰农业中要素替代、技术变化和规模经济，并将生产率增长分解为技术变化、规模经济和其他因素。
The study presents an empirical analysis of the structure of production in Irish agriculture. A single-output four-input generalised translog cost function model is utilised to obtain econometric measures of substitution between factor inputs, elasticities of input demand, neutral and non-neutral technical change and economies of scale. The cost function model is also used to decompose Tornqvist productivity gains into the contributions due to technical change, scale economies and other (residually measured) influences. Average annual Tornqvist productivity gains of 2.0% were found, with the technical change and scale economies effects being computed as 1.33% and -0.22% per year, respectively, leaving a (residual) measure of other unspecified effects of 0.89% per year.
