Does aid fuel corruption? New evidence from a cross-country analysis

open access: yesDevelopment Studies Research, 2021
This study estimates the effect of foreign aid on corruption using a Two-Step Least Squares method. We address endogeneity using instrumental variables that capture geographical and cultural proximities between donor and recipient countries.

A Robust Instrumental-Variables Estimator [PDF]

open access: yesThe Stata Journal: Promoting communications on statistics and Stata, 2012
The classical instrumental-variables estimator is extremely sensitive to the presence of outliers in the sample. This is a concern because outliers can strongly distort the estimated effect of a given regressor on the dependent variable. Although outlier diagnostics exist, they frequently fail to detect atypical observations because they are ...

Generalized Instrumental Variables

open access: yesCoRR, 2002
This paper concerns the assessment of direct causal effects from a combination of: (i) non-experimental data, and (ii) qualitative domain knowledge. Domain knowledge is encoded in the form of a directed acyclic graph (DAG), in which all interactions are assumed linear, and some variables are presumed to be unobserved. We provide a generalization of the

Orthogonal Polynomials for Seminonparametric Instrumental Variables Model [PDF]

open access: yes, 2014
We develop an approach that resolves a {\it polynomial basis problem} for a class of models with discrete endogenous covariate, and for a class of econometric models considered in the work of Newey and Powell (2003), where the endogenous covariate is ...

Determinantal Generalizations of Instrumental Variables

open access: yesJournal of Causal Inference, 2018
Linear structural equation models relate the components of a random vector using linear interdependencies and Gaussian noise. Each such model can be naturally associated with a mixed graph whose vertices correspond to the components of the random vector.

Mendelian randomization analyses in ocular disease: a powerful approach to causal inference with human genetic data

open access: yesJournal of Translational Medicine, 2022
Ophthalmic epidemiology is concerned with the prevalence, distribution and other factors relating to human eye disease. While observational studies cannot avoid confounding factors from interventions, human eye composition and structure are unique, thus,

A Gentle Introduction to Instrumental Variables

open access: yesJournal of Clinical Epidemiology, 2022
Instrumental variables (IV) is a central strategy for identifying causal effects in absence of randomized experiments. Clinicians and epidemiologists may find the intuition of IV easy to grasp by comparison to randomized experiments. Randomization is an ideal IV because treatment is assigned randomly, and hence unaffected by everything else. IV methods
