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 …

Intersection bounds: estimation and inference

Chernozhukov, Victor; Sokbae 'Simon' Lee; Rosen, Adam - Centre for Microdata Methods and Practice (CEMMAP) - 2012

We develop a practical and novel method for inference on intersection bounds, namely bounds defined by either the infimum or supremum of a parametric or nonparametric function, or equivalently, the value of a linear programming problem with a potentially infinite constraint set. We show that...

Local identification of nonparametric and semiparametric models

Chen, Xiaohong; Chernozhukov, Victor; Sokbae 'Simon' Lee; … - Centre for Microdata Methods and Practice (CEMMAP) - 2012

In parametric models a sufficient condition for local idenfication is that the vector of moment is differentiable at the true parameter with full rank derivative matrix. This paper shows that additional conditions are often needed in nonlinear, nonparametric models to avoid nonlinearities...

Inference for best linear approximations to set identified functions

Chandrasekhar, Arun; Chernozhukov, Victor; Molinari, … - Centre for Microdata Methods and Practice (CEMMAP) - 2012

This paper provides inference methods for best linear approximations to functions which are known to lie within a band. It extends the partial identification literature by allowing the upper and lower functions defining the band to be any functions, including ones carrying an index, which can be...

Teacher Shortages, Teacher Contracts and their Impact on Education in Africa

Froelich, Markus; Bourdon, Jean; Michaelowa, Katharina - School of Economics and Political Science, Universität … - 2007

Primary school enrolment rates are very low in francophone Africa. In order to enhance education supply, many countries have launched large teacher recruitment programmes in recent years, whereby teachers are no longer engaged on civil servant positions, but on the basis of (fixed-term)...

Combining Matching and Nonparametric IV Estimation: Theory and an Application to the Evaluation of Active Labour Market Policies

Lechner, Michael; Froelich, Markus - School of Economics and Political Science, Universität … - 2010

In this paper, we show how instrumental variable and matching estimators can be combined in order to identify a broader … often represent only a small subset of the entire population. By combining IV with matching, we can estimate also the …
