本文指定了一组一般条件,在这些条件下,可以使用在不同政策制度下生成的数据来确定政策的影响。我们表明,在模型的数据和结构上,一些政策影响可以在相对较弱的条件下识别出来。基于识别结果,我们开发了政策影响的估计器。我们讨论了一种非参数方法来实现估计,并讨论了半参数方法来降低条件维数。然后,我们利用这些思想提供了一个学费补贴影响的实证例子。虽然本文使用的框架相当狭窄,但我们相信这种方法可以应用于广泛的问题集。
This paper specifies a general set of conditions under which the impacts of a policy can be identified using data generated under a different policy regime. We show that some of the policy impacts can be identified under relatively weak conditions on the data and structure of a model. Based on the identification results we develop estimators of policy impacts. We discuss a nonparametric method to implement the estimation but also discuss semiparametric methods in order to reduce the conditioning dimension. We then provide an empirical example of the impact of tuition subsidies using the ideas. While the framework used in this paper is fairly narrow, we believe this approach can be applied to a broad set of problems.
