We study the effects of mobility costs in a model of wage bargaining between workers and firms, where there is instantaneous matching, free firm entry, heterogeneous labour, and workers' individual productivities are discovered by firms only after being hired. We derive the employment level and...

We analyze how frictions in the labour market influence the accumulation of general human capital. We find that investments in human capital benefits future employers, and that this positive externality leads to under-investments in human capital, and possibly top multiple, Pareto rankable...

A link between lack of employment and poverty is often made implicitly, but can rarely be enumerated in any sort of satisfactory manner. We would therefore like to ask the question: to what extent does acquiring employment increase a poor household’s probability of exiting poverty? Register...

Unreported labour by one worker in a firm increases the probability of detection for his fellow workers, not only for himself. The firm takes this external effect into account. As a consequence, unreported work becomes rationed by the firms demand, rather than determined by demand equal supply....

We study a matching model of the labor market, where wages are determined by rent sharing. Workers invest in human capital before they join the labour market.

We develop methods and employ similar sample restrictions to analyse differences in intergenerational earnings mobility across the United States, the United Kingdom, Denmark, Finland, Norway and Sweden. We examine earnings mobility among pairs of fathers and sons as well as fathers and daughters...

We present comparable evidence on intergenerational earnings mobility for Denmark, Finland, Norway, the UK and the US, with a focus on the role of gender and marital status. We confirm that earnings mobility in the Nordic countries is typically greater than in the US and in the UK, but find...

This paper examines the intergenerational correlation in unemployment in Norway and, by use of the sibling-difference method, separates that correlation into its causal and non-causal parts. Detailed register data covering the entire Norwegian population provide the long panel of data this...

Using Norwegian cancer registry data we study twin and non-twin siblings to decompose variation in cancer at most common sites and cancer mortality into a genetic, shared environment and individual (unshared environmental) component. Regardless the source of sibling variation, our findings...

In this paper some labour market consequences of transitions in the agriculture sector are examined by combining a 20-year unbalanced panel data set from Norwegian farm couples (households) and logit modeling of one-period transition probabilities. The multi-dimensionality of the problem follows...
