Complementarity and Aggregate Implications of Assortative Matching : A Nonparametric Analysis

Graham, Bryan S. - 2009

, potentially complementary, input fixed. We introduce a class of such reallocations -- correlated matching rules -- that includes … the status quo allocation, a random allocation, and both the perfect positive and negative assortative matching …

Moving the Goalposts : Addressing Limited Overlap in the Estimation of Average Treatment Effects by Changing the Estimand

Crump, Richard K. - 2006

Estimation of average treatment effects under unconfoundedness or exogenous treatment assignment is often hampered by lack of overlap in the covariate distributions. This lack of overlap can lead to imprecise estimates and can make commonly used estimators sensitive to the choice of...

Measuring the Effects of Segregation in the Presence of Social Spillovers : A Nonparametric Approach

Graham, Bryan S. - 2010

In this paper we nonparametrically analyze the effects of reallocating individuals across social groups in the presence of social spillovers. Individuals are either 'high' or 'low' types. Own outcomes may vary with the fraction of high types in one's social group. We characterize the average...

Identification and Estimation of Triangular Simultaneous Equations Models Without Additivity

Imbens, Guido W. - 2002

This paper investigates identification and inference in a nonparametric structural model with instrumental variables and non-additive errors. We allow for non-additive errors because the unobserved heterogeneity in marginal returns that often motivates concerns about endogeneity of choices...

On the Failure of the Bootstrap for Matching Estimators

Abadie, Alberto - 2006

Matching estimators are widely used for the evaluation of programs or treatments. Often researchers use bootstrapping … neighbor matching, the standard conditions for the bootstrap are not satisfied, leading the bootstrap variance to diverge from …

Identification and Efficiency Bounds for the Average Match Function under Conditionally Exogenous Matching

Graham, Bryan S. - 2016

. Consider the following matching mechanism: take a random draw from the `W=w_j` subgroup of the first population and match her … function (AMF), denote the expected output associated with this match. We show that (i) the AMF is identified when matching is … conditionally exogenous, (ii) conditionally exogenous matching is compatible with a pairwise stable aggregate matching equilibrium …
