本文评估了2000-2003年期间美国56个机场的生产力。与过去的工作不同，这项研究模拟了理想和不理想产出的联合生产（即，延迟）。将结果与不包括不良输出的模型的结果进行比较。结果表明，如果从模型中排除延误航班，许多大型但拥挤的机场被发现是有效的。在考虑了延误因素后，小型、不那么拥挤的机场也处于有效边界。最后，该模型也被用来分析其他变量的影响。
The paper assesses productivity of 56 US airports during the period 2000–2003. Unlike past work, this study models joint production of both desirable and undesirable outputs (i.e., delays) using the non-parametric directional output distance function. Results are compared to those from models that do not include undesirable outputs. The results show that if delayed flights are excluded from the model, many large but congested airports are found to be efficient. After accounting for delays, small, less congested airports are also found on the efficient frontier. Finally, the model is also used to analyze the effects of other variables.
