英文文献摘要:
This paper develops a specification test for functional form for models identified by moment restrictions, including IV and GMM settings. The general framework is one where the moment restrictions are specified as functions of data, a finite-dimensional parameter vector, and a nonparametric real function (an infinite-dimensional parameter vector). The null hypothesis is that the real function is parametric. The test is relatively easy to implement and its asymptotic distribution is known. The test performs well in simulation experiments.
本文开发了一种基于矩约束的模型功能形式规范测试,包括IV和GMM设置。一般框架是一个矩限制被指定为数据的函数,一个有限维参数向量,和一个非参数实函数(一个无限维参数向量)。零假设是实函数是参数的。该检验相对容易实现,它的渐近分布是已知的。该测试在仿真实验中取得了良好的效果。
