The net impact of development interventions can depend on the availability of close substitutes to the intervention. We analyze a randomized trial of an innovative anti-poverty program in South India which provides “ultra-poor” households with inputs to create a new, sustainable livelihood....

The paper examines the outcomes of youth not in education, employment or training (NEET) up to four years after the initial long-term spell of NEET. The paper covers outcomes of NEETs in relation to benefit receipt, education, employment and future inactivity. These outcomes are compared across...

Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts. We investigate the importance of heterogeneity using random-assignment data from Connecticut's Jobs First...

The paper estimates an earnings frontier by the method of Corrected Ordinary Least Squares (COLS) and categorizes households as efficient or inefficient based on some benchmark efficiency score and the estimated frontier. The spatial distribution of the poor and non poor households is then...

We propose an empirical likelihood-based method of inference for comparing inequality between two populations. A series of Monte Carlo experiments are used to assess our method’s finite sample performance. We illustrate our approach using some Canadian household income data.

We contrast two approaches to the prediction of latent variables in the model of factor analysis. The likelihood statistic is a sufficient statistic for the unobservables when sampling arises from the exponential family of distributions. Linear predictors, on the other hand, can be obtained as...

Medellín ha sido una de las ciudades más violentasdel mundo, pero la criminalidad ha venido reduciéndoseen los últimos años. La continuidad delsendero descendiente depende de la efectividadde las políticas públicas. Esta investigación evalúapolíticas públicas, tanto preventivas como...

This paper introduces a new approach to measuring the association between health and socioeconomic status. Measuring inequalities in health is difficult when health is measured qualitatively, specifically on an ordinal scale. This paper demonstrates a rank-based dependence measure - the copula -...

A copula is best described, as in Joe (1997), as a multivariate distribution function that is used to bind each marginal distribution function to form the joint. The copula parameterises the dependence between the margins, while the parameters of each marginal distribution function can be...
