Using the interaction of language of country of birth and age-at-arrival as instruments, we find strong evidence of a causal effect of English as Additional Language (EAL) on the native–immigrant wage gap for male employees in the UK.

I report on a study of the socioeconomic determinants of completed fertility in Mexico. An innovative Poisson double-hurdle count model is developed for the analysis. This methodological approach allows low- and high-order parities to be determined by two different data-generating mechanisms and...

The UK Department for Education (DfE) calculates contextualised value added (CVA) measures of school performance using administrative data that contain only a limited set of explanatory variables. Differences on schools’ intake regarding characteristics such as mother’s education...

We propose an estimator for models in which an endogenous dichotomous treatment affects a count outcome in the presence of either sample selection or endogenous participation using maximum simulated likelihood. We allow for the treatment to have an effect on both the participation or the sample...

In this paper we propose an estimator for models in which an endogenous dichotomous treatment affects a count outcome in the presence of either sample selection or endogenous participation using maximum simulated likelihood. We allow for the treatment to have an effect on both the sample...

type="main" xml:id="rssa12014-abs-0001" <title type="main">Summary</title> <p>The paper considers the problem of parameter estimation in a model for a continuous response variable Y when an ordinal explanatory variable X is missing for a substantial proportion of the sample and the selection mechanism (non-deletion from the...</p>

This paper presents code for fitting a FIML endogenous switching Poisson count model for cross-sectional data in Stata 7: the espoisson command. The Poisson process depends on an unobserved heterogeneity term, ; a set of explanatory variables, x; and an endogenous dummy, d. The endogenous dummy...

We focus on the effect of English deficiency on the native-immigrant wage gap for male employees in the UK using the first wave of the UK Household Longitudinal Survey. We show that the wage gap is robust to controls for age, region of residence, educational attainment and ethnicity. However,...
