Note: A Problem with the Decomposition of Technical Inefficiency into Scale and Congestion Components
指出Byrnes等人1988年提出的将无效率分解为规模和拥挤成分的方法可能因计算顺序不同而结果不同，从而给管理提供误导信号。
In 1988, Byrnes, Färe, Grosskopf and Lovell define a decomposition of inefficiency differentials into scale and congestion components. This note shows that the decomposition may be sensitive to the order in which the two components are calculated, and, consequently, use of the decomposition may result in misleading signals being given to management.
