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...

We formulate performance assessment as a problem of causal analysis and outline an approach based on the missing data principle for its solution. It is particularly relevant in the context of so-called league tables for educational, health-care and other public-service institutions. The proposed...

Building upon the social-risk management approach, this paper examines dimensions of household behavior that are important for risk management and reduction of vulnerability, beyond issues of consumption. This paper attempts to assess to what extent risk and vulnerability factors are relevant...

Logit models with random effects are now widely used in applied Statistics and Econometrics. They usually lead to intractable likelihood functions, as they involve integrals without closed form solution. Numerical integration can be used to compute the likelihood and software is available...

Anti-poverty policy in developing countries has focused mainly on the measurement and location of poverty and the targeting of policy towards those who are currently poor. Recently, the research effort has been extended to cover those judged to be not poor at present but vulnerable to poverty in...
