The effects of a job training program, Job Corps, on both employment and wages are evaluated using data from a randomized study. Principal stratification is used to address, simultaneously, the complications of noncompliance, wages that are only partially defined because of nonemployment, and unintended missing outcomes. The first two complications are of substantive interest, whereas the third is a nuisance. The objective is to find a parsimonious model that can be used to inform public policy… 
Bounds on Treatment Effects in the Presence of Sample Selection and Noncompliance: The Wage Effects of Job Corps
Randomized and natural experiments are commonly used in economics and other social science fields to estimate the effect of programs and interventions. Even when employing experimental data,
Bounding Average and Quantile Effects of Training on Employment and Unemployment Durations under Selection , Censoring , and Noncompliance
Using data from a randomized evaluation of the Job Corps (JC) training program, we estimate nonparametric bounds for average and quantile treatment effects of training on employment and unemployment
Assessing Causal Effects in a Longitudinal Observational Study With “Truncated” Outcomes Due to Unemployment and Nonignorable Missing Data
Abstract Important statistical issues pervade the evaluation of training programs’ effects for unemployed people. In particular, the fact that offered wages are observed and well-defined only for
Using secondary outcomes and covariates to sharpen inference in randomized experiments with noncompliance
We develop new methods for analyzing randomized experiments with noncompliance and, by extension, instrumental variable settings, when the often controversial, but key, exclusion restriction
Bounds on Average and Quantile Treatment Effects on Duration Outcomes Under Censoring, Selection, and Noncompliance
Abstract We consider the problem of assessing the effects of a treatment on duration outcomes using data from a randomized evaluation with noncompliance. For such settings, we derive nonparametric
Using Secondary Outcomes to Sharpen Inference in Randomized Experiments With Noncompliance
We develop new methods for analyzing randomized experiments with noncompliance and, by extension, instrumental variable settings, when the often controversial, but key, exclusion restriction
Combining Matching and Nonparametric Instrumental Variable Estimation: Theory and An Application to the Evaluation of Active Labour Market Policies
We show how instrumental variable and matching estimators can be combined in order to identify a broader array of treatment effects. Instrumental variable (IV) estimators are known to estimate
Going Beyond Late: Bounding Average Treatment Effects of Job Corps Training
We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to evaluate the effectiveness of the Job Corps (JC) training program for
Empirical Essays on Causal Effects of Job Training Programs: Evidence From Korea
This dissertation comprises two chapters that are related to the research topics in Korean job training programs using administrative data. The first chapter examines the effectiveness of the
Using secondary outcomes and covariates to sharpen inference in instrumental variable settings
We derive nonparametric bounds for intention-to-treat effects on a primary outcome for the subpopulations defined by the values of the potential treatment status under each value of the instrument,

TLDR
In this paper, it is illustrated how recently developed methods for the estimation of causal effects from continuous treatments can be used to learn about the consequences of heterogeneous lengths of enrollment in the evaluation of training programs.

Identification of Causal Effects Using Instrumental Variables
TLDR
It is shown that the instrumental variables (IV) estimand can be embedded within the Rubin Causal Model (RCM) and that under some simple and easily interpretable assumptions, the IV estimand is the average causal effect for a subgroup of units, the compliers.

TLDR
Comparing the causal estimand of the new treatment of the complier average causal effect with an estimator based on an alternative, nonignorable model for the missing data process, developed by Frangakis and Rubin, and a new missing data model that is specially suited for models with instrumental variables, but makes different substantive assumptions are analyzed.
