Let $d_{\bm Z}>d_{\bm \Phi}>1$ and let the solution set for the budget-assignment parameter $\bm\theta$ be defined through subset selection over…

Weak-instrument conjecture. Active learning approaches could help address the problem of weak instruments by selecting values of $Z$ that induce maximal variation in $X$.

Let ridge IV denote the instrumental-variable estimator obtained by adding an $L_2$ penalty to the GMM objective function, with penalty parameter $b[?m\lambdab[0m$. An appropriate…

The CLS framework combines estimators using a proportion parameter, and this parameter need not have a closed-form expression. CLS applicability conjecture. The CLS framework could…
