Doubly robust estimation of the local average treatment effect curve
(Wiley Blackwell Publishing, Inc, 2015-03)
We consider estimation of the causal effect of a binary treatment on an outcome, conditionally on covariates, from observational studies or natural experiments in which there is a binary instrument for treatment. We describe ...
The effect of the Mediterranean Diet on lifespan: A treatment-effect survival analysis of a population-based prospective cohort study in Southern Italy
(2021-02-01)
Background: The Mediterranean diet (MedDiet) is associated with good health. We aimed to estimate the effect of levels of adherence to the MedDiet on lifespan by performing treatment effects survival analysis. Methods: A ...
Instrumental variables and the sign of the average treatment effect
(2018-01)
This paper considers identification and inference about the sign of the average effect of a binary endogenous regressor (or treatment) on a binary outcome of interest when a binary instrument is available. In this setting, ...
Nonparametric Estimation of Causal Effects in Observational Studies
(Sociedade Brasileira de Econometria, 2010)
Efficient estimation of data combination models by the method of Auxiliary-to-Study Tilting (AST)
(Amer Statistical Assoc, 2016-04-02)
We propose a locally efficient estimator for a class of semiparametric data combination problems. A leading estimand in this class is the average treatment effect on the treated (ATT). Data combination problems are related ...
Effect of pre-germinal treatment and temperature on the germination of achenes of Baccharis dracunculifolia DC
(2019-01-01)
The species Baccharis dracunculifolia, known as alecrim-do-campo is very rough, of great economic importance, recommended for recovery of degraded areas, but is little explored by propagation through seeds. In order to ...
Economic performance of Brazilian manufacturing firms: a counterfactual analysis of innovation impacts
(SPRINGER, 2010)
This article assesses if innovators outperform non-innovators in Brazilian manufacturing during 1996-2002. To do so, we begin with a simple theoretical model and test the impacts of technological innovation (treatment) on ...
The Impact of Social Interventions: Nonparametric Identification from Choice-Based Samples
(Sociedade Brasileira de Econometria, 2010)
Effects of heat treatments on the electrocatalytic activity of Pt-Ru/C for methanol oxidation
(2008-12-01)
The Pt-Ru/C materials of this study were prepared by a microemulsion method with fixed water to surfactant molar ratio and heat treated at low temperatures, to avoid changes in the average particle size, in different ...
