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 Estimation of Average Treatment Effects by Changing the Estimand
Crump, Richard K.; Hotz, V. Joseph; Imbens, Guido W.; … - Department of Economics, School of Business - 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...

Dealing with Limited Overlap in Estimation of Average Treatment Effects
Crump, Richard K.; Hotz, V. Joseph; Imbens, Guido W.; … - Department of Economics, School of Business - 2004
Estimation of average treatment effects under unconfounded or ignorable 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 specification....

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 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 …
