What is the value of knowing the propensity score for estimating average treatment effects?
Froelich, Markus - School of Economics and Political Science, Universität … - 2002
Propensity score matching is widely used in treatment evaluation to estimate average treatment effects. Nevertheless …

Nonparametric IV estimation of local average treatment effects with covariates
Froelich, Markus - School of Economics and Political Science, Universität … - 2002
In this paper nonparametric instrumental variable estimation of local average treatment effects (LATE) is extended to incorporate confounding covariates. Estimation of local average treatment effects is appealing since their identification relies on much weaker assumptions than the...

A generalization of the balancing property of the propensity score
Froelich, Markus - School of Economics and Political Science, Universität … - 2002
Propensity score matching is a nonparametric technique frequently used for estimating average treatment effects. Yet … its applicability is not confined to treatment evaluation. In this paper the propensity score property is generalized to … the setting of selection on unobservables. It is shown that propensity score matching can be used to decompose effects due …

Regression discontinuity design with covariates
Frölich, Markus - School of Economics and Political Science, Universität … - 2007
In this paper, the regression discontinuity design (RDD) is generalized to account for differences in observed covariates X in a fully nonparametric way. It is shown that the treatment effect can be estimated at the rate for one-dimensional nonparametric regression irrespective of the dimension...

A Note on the Relation of Weighting and Matching Estimators
Lechner, Michael - School of Economics and Political Science, Universität … - 2007
This paper compares the inverse-probability-of-selection-weighting estimation principle with the matching principle and … derives conditions for weighting and matching to identify the same and the true distribution, respectively. This comparison …

Optimal Smoothing for aComputationally andStatistically Efficient SingleIndex Estimator
Xia, Yingcun; Härdle, Wolfgang; Linton, Oliver - Sonderforschungsbereich Ökonomisches Risiko <Berlin> - 2009
In semiparametric models it is a common approach to under-smooth the nonparametric functions inorder that estimators of the finite dimensional parameters can achieve root-n consistency. The requirementof under-smoothing may result as we show from inefficient estimation methods or technical...

Independent Component Analysis Via Copula Techniques
Chen, Ray-Bing; Guo, Meihui; Härdle, Wolfgang; Huang, … - Sonderforschungsbereich Ökonomisches Risiko <Berlin> - 2007
Independent component analysis (ICA) is a modern factor analysis tool developed in the last two decades. Given p-dimensional data, we search for that linear combination of data which creates (almost) independent components. Here copulae are used to model the p-dimensional data and then...

Adaptive pointwise estimation in time-inhomogeneous time-series models
Cizek, Pavel; Härdle, Wolfgang; Spokoiny, Vladimir - Sonderforschungsbereich Ökonomisches Risiko <Berlin>
This paper offers a new method for estimation and forecasting of the linear and nonlinear time series when the stationarity assumption is violated. Our general local parametric approach particularly applies to general varying-coefficient parametric models, such as AR or GARCH, whose coefficients...
