Instrumental Variables, Local Instrumental Variables and Control Functions [PDF]
Working Paper Series, 2002 We consider the identification of the average treatment effect in models with continuous endogenous variables whose impact is heterogeneous. We derive a testable restriction that allows us to assess the degree of unobserved heterogeneity.

Testability of Instrumental Variables in Linear Non-Gaussian Acyclic Causal Models [PDF]
Entropy, 2022 This paper investigates the problem of selecting instrumental variables relative to a target causal influence X→Y from observational data generated by linear non-Gaussian acyclic causal models in the presence of unmeasured confounders.

Latent class instrumental variables and the monotonicity assumption [PDF]
Emerging Themes in Epidemiology, 2020 A key aspect of the article by Lousdal on instrumental variables was a discussion of the monotonicity assumption. However, there was no mention of the history of the development of this assumption.

Cointegration Tests Using Instrumental Variables
International Journal of Empirical Economics, 2022 This paper proposes new cointegration tests based on instrumental variable (IV) estimation. An important property of our tests is that the asymptotic distribution remains standard normal (or Chi-square) regardless of the number of regressors, differing ...

Algorithm for adaptive observation based on method of instrumental variables [PDF]
E3S Web of Conferences, 2023 When the input signal and the output value of the object of control cannot be measured accurately, the state vector is estimated. The instrumental variables (IVs) method is a commonly used parameter estimation method [1-10].

REndo: Internal Instrumental Variables to Address Endogeneity
Journal of Statistical Software, 2023 Endogeneity is a common problem in any causal analysis. It arises when the independence assumption between an explanatory variable and the error in a statistical model is violated.

Incarceration and mortality in the United States
SSM: Population Health, 2021 The ongoing COVID-19 pandemic has spotlighted the role of America's overcrowded prisons as vectors of ill health, but robust analyses of the degree to which high rates of incarceration impact population-level health outcomes remain scarce. In this paper,

Instrumental variable analysis [PDF]
Nephrology Dialysis Transplantation, 2012 The main advantage of the randomized controlled trial (RCT) is the random assignment of treatment that prevents selection by prognosis. Nevertheless, only few RCTs can be performed given their high cost and the difficulties in conducting such studies.
