摘要

研究了具有多值处理变量的回归不连续设计(RDD)的辨识和估计问题。我们还允许包含协变量。我们表明,如果没有额外的信息,治疗效果是不确定的。我们给出了识别时滞时滞的充分必要条件,并给出了条件时滞时滞的加权平均。我们表明,如果以协变量为条件的多个处理的第一阶段不连续是线性独立的,那么就有可能用方便可识别的权重识别处理效果的多变量加权平均。此外,如果治疗效果不随某些协变量而变化,或者可以假设一个灵活的参数结构,则有可能识别(实际上是过度识别)所有治疗效果。过度识别可以用来检验这些假设。我们提出了一个简单的估计器,它可以在打包软件中编程为两阶段最小二乘回归,并且也可以使用打包的标准误差和测试。最后,我们实施了我们的方法,以确定不同类型的保险覆盖范围对医疗保健利用的影响,如Card, Dobkin和Maestas(2008)。

Regression discontinuity design with multivalued treatments

We study identification and estimation in the regression discontinuity design with a multivalued treatment. We show that heterogeneity in the first stage discontinuities can be used for the identification of the marginal treatment effects under an alternative assumption, namely, the homogeneity of the LATEs along some covariates. This assumption can often be tested and relaxed. Our estimator can be programmed as a simple two-stage least squares regression, and packaged standard errors and tests can also be used. We apply our method to estimate the effect of Medicare insurance coverage on health care utilization.

期刊介绍: The Journal of Applied Econometrics is an international journal published bi-monthly, plus 1 additional issue (total 7 issues). It aims to publish articles of high quality dealing with the application of existing as well as new econometric techniques to a wide variety of problems in economics and related subjects, covering topics in measurement, estimation, testing, forecasting, and policy analysis. The emphasis is on the careful and rigorous application of econometric techniques and the appropriate interpretation of the results. The economic content of the articles is stressed. A special feature of the Journal is its emphasis on the replicability of results by other researchers. To achieve this aim, authors are expected to make available a complete set of the data used as well as any specialised computer programs employed through a readily accessible medium, preferably in a machine-readable form. The use of microcomputers in applied research and transferability of data is emphasised. The Journal also features occasional sections of short papers re-evaluating previously published papers. The intention of the Journal of Applied Econometrics is to provide an outlet for innovative, quantitative research in economics which cuts across areas of specialisation, involves transferable techniques, and is easily replicable by other researchers. Contributions that introduce statistical methods that are applicable to a variety of economic problems are actively encouraged. The Journal also aims to publish review and survey articles that make recent developments in the field of theoretical and applied econometrics more readily accessible to applied economists in general.
