Exact Finite Sample Test Statistics for Restricted Reduced Forms: A Generalization of "Student's" Result
提出了过度识别排除限制中简化型系数的检验统计量和估计量，这些统计量在原假设下不依赖未知参数，其中一个恰好是学生t分布，对供需双方程框架进行了推广。
Test statistics and estimators for reduced-form coefficients involved in overidentifying exclusion restrictions are proposed. The test statistics, under the null hypothesis, do not depend on unknown parameters. One of the test statistics is exactly a Student t under the null hypothesis. A two equation (supply/demand) framework is used , but generalizations are suggested.
