本文研究由线性矩不等式定义的部分辨识参数的线性函数和标量子向量的一致有效推理。我们提出的过程相当于自举四个精心构造的“扰动”线性规划问题的值函数,而不需要研究者在参数空间上网格。我们一致有效性的低层条件依赖于微分拓扑中的Sard定理的应用。我们的方法对于真的部分辨识参数是渐近保守的,但在较弱的假设下是有效的,在有限样本中表现良好,并且计算简单。

英文摘要:
This paper considers uniformly valid inference for linear functionals and scalar subvectors of partially identified parameters defined by linear moment inequalities. Our proposed procedure amounts to bootstrapping the value functions of four carefully constructed "perturbed" linear programming problems, and does not require the researcher to grid over the parameter space. Our low-level conditions for uniform validity rely on an application of Sard's Theorem from differential topology. Our procedure is asymptotically conservative for the true partially identified parameter, but is valid under weak assumptions, performs well in finite samples, and is computationally simple to implement.
