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 …

Anchoring Bias and Covariate Nonresponse
Vazquez-Alvarez, Rosalia - School of Economics and Political Science, Universität … - 2003
Non-random item nonreponse makes identification if parameters problematic. Such nonresponse can occur with respect to both dependent and conditioning variables. A method often used to reduce nonresponse is that of adding unfolding brackets as follow up to open-ended questions. With these,...

Empirical pricing kernel estimation using a functional gradient descent algorithm based on splines
Audrino, Francesco; Meier, Pirmin - School of Economics and Political Science, Universität … - 2012
We propose a new methodology to estimate the empirical pricing kernel implied from option data. In contrast to most of the studies in the literature that use an indirect approach, i.e. first estimating the physical and risk-neutral densities and obtaining the pricing kernel in a second step, we...

Realized Copula
Fengler, Matthias; Okhrin, Ostap - School of Economics and Political Science, Universität … - 2012
We introduce the notion of realized copula. Based on assumptions of the marginal distributions of daily stock returns and a copula family, realized copula is defined as the copula structure materialized in realized covariance estimated from within-day highfrequency data. Copula parameters are...
