The proposed method has two-steps: 􀀌rst, the propensity score is estimated, and second, a blocking estimation procedure using this estimate is used to compute treatment e􀀋ects. In both cases, the estimators are proved to be consistent. Monte Carlo results show a better performance than other procedures based on the propensity score. Finally, these estimators are applied to a job training dataset.  \nJEL: C14, C31  \nKeywords: Treatment E􀀋ects, Fractile Graphical Analysis  \n􀀃 Corresponding Author: Department of Economics, City University London, D306 Social Sciences Bldg, Northampton Square, London EC1V 0HB, UK.

In this case, a treatment refers to a certain program whose bene􀀌tsare potentially obtainable by those selected for participation (treated) and it has no e􀀋ect on a control group (non-treated) .  \nEstimating average treatment e􀀋ects (ATE), which refers to the mean e􀀋ect of the program on a given outcome variable in parametric and nonparametric environments (see Angrist and Krueger, 1999, Imbens, 2004) has been a central issue in the literature. Lehmann (1974) and Docksum (1974) introduced the concept of quantile treatment e􀀋ects (QTE) as the di􀀋erence of the quantiles of the treated and control outcome distribut","cbCaijfly3GteUnU","https://ap.wps.com/l/cbCaijfly3GteUnU","pdf",432714,47,"English","# Introduction\n## Treatment effects in program evaluation\n## Nonexperimental identification and selection bias\n## Propensity score based estimation methods","[{\"question\":\"What is the document’s main objective?\",\"answer\":\"To construct nonparametric estimators for ATE and QTE using Fractile Graphical Analysis and to evaluate their performance and consistency.\"},{\"question\":\"How does the proposed method estimate ATE and QTE?\",\"answer\":\"It uses a two-step process: first estimate the propensity score, then perform a blocking estimation procedure based on that estimate to compute treatment effects.\"},{\"question\":\"What assumptions are used to identify treatment effects in the paper?\",\"answer\":\"The approach relies on the identifying assumption that selection to treatment is based on observable characteristics, together with a unconfoundedness-style conditional independence condition.\"}]","Nonparametric Estimation of ATE and QTE - An Application of Fractile Graphical Analysis - Discussion Paper Series - No. 10/06 | PDF",118]
