I discuss the application of capture-recapture methods to estimating the total number of deaths in armed conflicts, and propose an alternative method based on a trivariate discrete choice model. Data come from the 'Truth and Reconciliation Commission' (TRC) of Peru, around 25000 deaths,...

The economic literature has largely overlooked the importance of repeat and circular migration. The paper studies this behavior by analyzing the number of exits and the total number of years away from the host country using count data models and panel data from Germany. More than 60% of migrants...

In this paper we suggest an alternative approach to testing for the dual structure of the labour market. The novelty of the suggested approach is that rather than considering wage determination we concentrate on the turnover. To perform the test we suggest using a latent class count data...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

The Bologna process aims at creating a European Higher Education Area where intercountry mobility of students and staff, as well as workers holding a degree, is facilitated. While several aspects of the process deserve wide public support, the reduction of the length of the first cycle of...

In this paper we investigate whether higher education (HE) produces non-pecuniary returns via a reduction in the consumption of health-damaging substances. In particular, the paper focuses on studying the smoking intensity of British individuals. We use data on current smokers from the 1970...

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...

The paper makes three contributions to the economics literature on entrepreneurship. We offer a new measure of entrepreneurship which accounts for variations in persistence in selfemployment and as a result avoids the weakness of approaches which categorise an individual as an entrepreneur by...

We investigate the impact on earnings inequality of a selective education system in which school assignment is based on initial test scores. We use a large, representative household panel survey to compare adult earnings inequality of those growing up under a selective education system with...

This paper examines how productivity effects of human capital and innovation vary at different points of the conditional productivity distribution. Our analysis draws upon two large unbalanced panels of 6,634 enterprises in Germany and 14,586 enterprises in the Netherlands over the period...
