This survey of the Norwegian purse seine fleet licensed to fish blue whiting focuses on the relationship between restricted fisheries, such as spring-spawning herring, North Sea herring, mackerel, and capelin, and unrestricted fisheries, of which blue whiting is the most important. To model the...

Spatial management of a fishery under parameter uncertainty is analyzed. The habitat is divided into two areas, and the effort level in the two areas may be different. The migration of biomass between the areas follows a diffusion process; two different specifications are considered. The model...

Why did the Lofoten cod fishery in Norway – a fishery on one of the world's richest spawning grounds - remain less productive than alternative industries until the mid-1960s, despite important modernization of the fleet and fishing gear, improvements in technology and institutional change? We...

The existing fisheries economics literature analyzes compliance problems by treating the fishing firm as one cohesive unit, but in many cases, violations are committed by agents acting on behalf of a firm. To account for this, we analyze the principal-agent relationship within the fishing firm....

Using Norwegian individual register data of young workers, from the period 1986-2008, we analyze whether there are large and persistent negative relationships between unemployment and the risk of repeated unemployment and being out of labor force. A nearest-neighbor propensity score matching...

A model for matched data with two types of unobserved heterogeneity is considered one related to the observation unit, the other to units to which the observation units are matched. One or both of the unobserved components are assumed to be random. This mixed model allows identifi cation of the...

There is relatively little research on peer effects in teenage motherhood despite the fact that peer effects, and in particular social interaction within the family, are likely to be important. We estimate the impact of an elder sister’s teenage fertility on the teenage childbearing of their...

This paper provides evidence on the returns to schooling in current and lifetime earnings. We use these results to assess the importance of life-cycle bias in earnings regressions using current earnings as proxy for lifetime earnings. To account for the endogeneity of schooling, we apply three...

In Scandinavia, the provision of health care services has been, almost entirely, the responsibility of the public health care system. However, in the last five to seven years there has been remarkable growth in the private health care market. These health care services are obtained normally...

We demonstrate how age-adjusted inequality measures can be used to evaluate whether changes in inequality over time are because of changes in the age structure. In particular, we explore the hypothesis that the substantial rise in earnings inequality since the early 1980s is driven by the large...
