Dano (2005)
Earnings, annualemployment rate,disposable income,public transfer income
Road traffic accidents
Usesdifference-in-differencesmatching estimator withpanel constructed fromregister data. One-to-onematching withoutreplacement based on linearindex from propensity score.Checks for balancing
Finds an impact onearned income for olderand low incomeindividuals. Also showscompensating effects ofpublic transfers in theDanish system
Frolich
et al.
(2004)
Labor market outcomes:reintegration into thelabor force
Vocational rehabilitationprogram in westernSweden
Multiple treatments withmatching based onmultivariate balancingscores computed frommultinomial probit models.Uses nearest neighbourswith replacement. Checksfor balancing of covariatesafter matching
Finds a negative effect ofrehabilitation. Many ofthe effects areinsignificant: manycontrols are usedrepeatedly in thematching
García-Gómez andLópez-Nicolás (2006)
Employment, income,SAH
Health shocks andemployment shocks
Use matcheddifference-in-differencesestimator. Combine exactmatching on pre-treatmentoutcomes with propensityscore matching. Use bothnearest neighbor andkernel-smoothed matching
Find effects of healthshocks on employmentand activity. Also find aneffect of transition tounemployment on SAH
