Bandwidth Selection and the Estimation of Treatment Effects with Unbalanced Data
Galdo, Jose; Smith, Jeffrey Andrew; Black, Dan - Institute for the Study of Labor (IZA) - 2007
This paper addresses the selection of smoothing parameters for estimating the average treatment effect on the treated using matching methods. Because precise estimation of the expected counterfactual is particularly important in regions containing the mass of the treated units, we define and...

A Simple Method to Visualize Results in Nonlinear Regression Models
Henderson, Daniel J.; Kumbhakar, Subal C.; Parmeter, … - Institute for the Study of Labor (IZA) - 2012
A simple graphical approach to presenting results from nonlinear regression models is described. In the face of multiple covariates, 'partial mean' plots may be unattractive. The approach here is portable to a variety of settings and can be tailored to the specific application at hand. A simple...

Inference on Causal Effects in a Generalized Regression Kink Design
Card, David; Lee, David S.; Pei, Zhuan; Weber, Andrea - Institute for the Study of Labor (IZA) - 2015
We consider nonparametric identification and estimation in a nonseparable model where a continuous regressor of interest is a known, deterministic, but kinked function of an observed assignment variable. This design arises in many institutional settings where a policy variable (such as weekly...

Identification and Estimation of Causal Mechanisms and Net Effects of a Treatment under Unconfoundedness
Flores, Carlos A.; Flores-Lagunes, Alfonso - Institute for the Study of Labor (IZA) - 2009
An important goal when analyzing the causal effect of a treatment on an outcome is to understand the mechanisms through which the treatment causally works. We define a causal mechanism effect of a treatment and the causal effect net of that mechanism using the potential outcomes framework. These...

The Effect of Disability on Labour Market Outcomes in Germany: Evidence from Matching
Lechner, Michael; Vazquez-Alvarez, Rosalia - Institute for the Study of Labor (IZA) - 2003
If labour market policies aimed at people with disabilities are effective, we should observe no significant difference in labour market outcomes between disable and non-disable individuals. This paper examines the impact of disability status on labour market outcomes using matching methods...
