The purpose of this paper is also to analyze the importance of unemployment and other social factors as risk factors for impaired mental health. It departs from previous studies in that we make use of information about first admissions to a psychiatric hospital or ward as our measure of mental...

We analyse what determines the incidence of unemployment among Danish employees by estimation of a logit model for becoming unemployed. Our data is incomplete in the sense that we do not observe whether a transition was caused by the person quitting or being laid off, so we apply the...

A new class of regression type models termed essentially linear models is proposed. The class is characterized by geometric considerations. Within the class the distribution of the maximum likelihood estimator is easily approximated by a natural extension of the p-formula even though the MLE...

Political involvement in the operation of an enterprise, whether it is private or state owned, creates opportunities for interest groups to influence the allocation of resources. I analyze how the influence externality arising from the interest groups' lobby activity disables the Coase Theorem....

We document the distribution and changes in the distribution of earnings in Finland from 1971 to 1990. Use a large representative set of data, collected from the population censuses.

It turns out that the Oaxaca-Blinder wage decomposition is inadequate when it comes to calculation of separate contributions for indicator variables. The contributions are not robust against a change of reference group. I extend the Oaxaca-Blinder decomposition to handle this problem.

The effect of children and career interruptions on the family gap is analysed based on longitudinal data covering the years 1980-1995. The estimated model controls for unobserved time-constant heterogeneity. The results show that when controlling for unobserved heterogeneity, the negative effect...

We analyze the retirement behaviour of married couples using a new bi-variate proportional hazard model. This model generalizes the traditional univariate duration analysis to include a family-wide joint retirement process that induces both spouses to retire at the same time. The model is...

We discuss the normal vairance-mean mixture model from a semi-parametric point of view, i.e. we let the mixing distribution belong to a non parametric family. The main results are consistency of the non parametric maximum likelihood estimator in this case, and construction of an asymptotically...

This paper investigates the effect of severe mental illness on the capacity to hold a job and to earn an income. We find that the employment rate is reduced with about 1/3 during the development of the disease. Hospital admission seems to stabilize employment for all diagnoses. The employment...
