英文摘要：
This paper introduces measures for how each moment contributes to the precision of parameter estimates in GMM settings. For example, one of the measures asks what would happen to the variance of the parameter estimates if a particular moment was dropped from the estimation. The measures are all easy to compute. We illustrate the usefulness of the measures through two simple examples as well as an application to a model of joint retirement planning of couples. We estimate the model using the UK-BHPS, and we find evidence of complementarities in leisure. Our sensitivity measures illustrate that the estimate of the complementarity is primarily informed by the distribution of differences in planned retirement dates. The estimated econometric model can be interpreted as a bivariate ordered choice model that allows for simultaneity. This makes the model potentially useful in other applications.

中文摘要：
本文介绍了在GMM设置中，每一时刻如何影响参数估计精度的措施。例如，其中一个度量询问，如果从估计中删除某个特定时刻，参数估计的方差会发生什么变化。这些度量值都很容易计算。我们通过两个简单的例子以及对夫妻共同退休计划模型的应用来说明这些措施的有用性。我们使用UK-BHPS对模型进行了估计，并发现休闲互补的证据。我们的敏感性指标表明，互补性的估计主要是由计划退休日期的差异分布决定的。估计的计量经济学模型可以解释为允许同时性的双变量有序选择模型。这使得该模型在其他应用程序中可能有用。
