In this paper, we propose a new approach to estimating sample selection models that combines Generalized Tukey Lambda (GTL) distributions with copulas. The GTL distribution is a versatile univariate distribution that permits a wide range of skewness and thick- or thin-tailed behavior in the data...

If the disturbances of a linear regression model are skewed and/or thick-tailed, a maximum likelihood estimator is efficient relative to the customary Ordinary Least Squares (OLS) estimator. In this paper, we specify a highly flexible Generalized Tukey Lambda (GTL) distribution to model skewed...

This meta-analytical review of empirical studies of the impact of schooling on entrepreneurship selection and performance in developing economies looks at variations in impact across specific characteristics of the studies. A marginal year of schooling in developing economies raises enterprise...

One would expect that family income is an important positive factor in children's school attainment. However, evidence is often tainted by the lack of control for parental ability, since at least a portion of ability is transferred genetically to children. This paper uses a sample of adopted...
