More on Confidence Intervals for Partially Identified Parameters
扩展了Imbens和Manski（2004）关于区间识别参数置信区间的分析，指出其最终结果隐含了对干扰参数的局部超有效估计假设。
This paper extends Imbens and Manski's (2004) analysis of confidence intervals for interval identified parameters. The extension is motivated by the discovery that for their final result, Imbens and Manski implicitly assumed locally superefficient estimation of a nuisance parameter.
