Rationalising inefficiency in dairy production: evidence from an over-time approach
研究认为低效率可能是农场战略性自我调整过程的一部分，利用瑞典奶牛场面板数据，发现部分农场的低效率是暂时的，是向高效率高动物福利转型的理性决策。
Abstract We argue that inefficiency can be part of a strategic self-repositioning adjustment process beyond the general interpretation of poor performance. Based on the rational inefficiency hypothesis, we examine the simultaneous dynamics of efficiency and animal welfare improving investments over time in dairy farms. Using rotating panel data from Swedish dairy farms and implementing multidirectional efficiency analysis and Markov transitional dynamic analysis, the paper provides evidence that for some farms inefficiency is temporary and part of rational decision along their trajectory towards multi-efficiency (high efficiency-high animal welfare). The findings show the importance of time dynamics in efficiency achievements with implications to cross-sectional view.
