The objective of this paper is to extend the results on Pseudo Maximum Likelihood (PML) theory derived in Gourieroux, Monfort, and Trognon (GMT) (1984) to a situation where the first four conditional moments are specified. Such an extension is relevant in light of pervasive evidence that...

With more than a fifth of the population being foreign citizens, Switzerland offers an ideal case to study the migrant health gap and the role of labour market status on the migrants' health. This paper examines the potential health gaps between Swiss nationals and different migrant groups (from...

This paper uses data from the Swiss Labour Force Survey to evaluate the existence of the healthy immigrant effect (HIE) which would translate in i. a health advantage of immigrants upon their arrival in Switzerland compared to individuals with similar characteristics but Swiss-born and ii. an...

The purpose of this paper is to derive a Rao's efficient score statistic for testing for heteroscedasticity in an error components model with only individual effects. We assume that the individual effect exists and therefore do not test for it. In addition, we assume that the individual effects,...

The aim of this paper is to model a liberal profession, in this case physicians. We propose a model in which the physician acts in the same way as an agent who maximises his utility function subject to his budget constraint, while at the same time being able to affect his rate of remuneration....

In this paper, we develop a new numerical method to estimate a multivariate probit model. To this end, we derive a new decomposition of normal multivariate integrals that has two appealing properties. First, the decomposition may be written as the sum of normal multivariate integrals, in which...
