Ill-posed estimation in high-dimensional models with instrumental variables
This paper is concerned with inference about low-dimensional components of a high-dimensional parameter vector beta(0) which is identified through instrumental variables. We allow for eigenvalues of the expected outer product of included and excluded covariates, denoted by M, to shrink to zero as th...
