Matching estimators with few treated and many control observations
(2018-09)
We analyze the properties of matching estimators when there are few treated, but many control observations. We show that, under standard assumptions, the nearest neighbor matching estimator for the average treatment effect ...
An optimization -based matching estimator : large and small sample properties
(Universidad de Chile, 2014-12)
This work proposes a novel matching estimator where weights and the choice of neighbors
used are endogenously determined by solving an optimization problem. The estimator is
non-parametric and is based on nding, for ...
Large sample properties of an optimization-based matching
(Universidad de Chile, Facultad de Economía y Negocios, 2014)
This paper mainly concerns the the asymptotic properties of the BLOP matching estimator
introduced by D´ıaz, Rau & Rivera (Forthcoming), showing that this estimator of the ATE attains
the standard limit properties, and ...
Concept of Matching Parallelepiped and its use in the correspondence problem
(1999-12-01)
In this paper, the concept of Matching Parallelepiped (MP) is presented. It is shown that the volume of the MP can be used as an additional measure of `distance' between a pair of candidate points in a matching algorithm ...

Geometric Filtering of Matches Between Points in Bands of Hyperspectral Cubes
(Ieee-inst Electrical Electronics Engineers Inc, 2019-03-01)
Hyperspectral images can present low contrast, noisy pixels, and illumination variation among bands, which complicates the extraction of interest points and reduces the number of reliable image matches affecting subsequent ...
Dual Labor Markets and Labor Protection in an Estimated Search and Matching Model
(Universidad Alberto Hurtado. Facultad de Economía y Negocios, 2015)
An optimization-based propensity score matching estimator
(2015)
This paper proposes a simple alternative for the treatment e ect estimators based on match-
ing on the estimated propensity score. In this approach, both weights and the number of coun-
terfactuals employed in realizing ...
