Building on the testable implications for IV validity underlying local average treatment effect (LATE) estimation, we (i) propose a simple testing procedure that may accommodate high-dimensional covariates and (ii) demonstrate that it can also detect biases arising from misspecified IV...

Instrumental variables (IV) methods are central to applied microeconomics. While classical approaches assume linear models with constant effects, recent literature has shifted toward the local average treatment effect (LATE) framework to accommodate heterogeneous treatment effects. This paper...

Purpose The purpose of this paper is to design and validate a reliable and comprehensive instrument to assess the influence of sustainable supply chain management (SSCM) practices on sustainable performance in hospitals. Design/methodology/approach A systematic and mixed-method approach was used...
