Norwegian registry data is used to investigate the location decisions of a full population cohort of young adults as they complete their education, establish separate households and form their own families. We find that the labor market opportunities and family ties of both partners affect these...

We analyse the effects of different labour market policies — employment protection, unemployment benefits and payroll taxes — on job creation and technology choices in a model where firms are randomly matched with workers of different productivity and wages are determined by ex-post...

Using rich administrative data from Norway, we evaluate a 1998 work-encouraging reform targeted at single parents. We especially focus on educational performances for children of the involved single mothers. For all children of single mothers, the effect on school grades at completion of junior...

We analyse how the presence of trade unions affects the pattern of mergers in an international oligopoly and the welfare implications thereof. We find that an international merger results in lower wages for all firms. A national merger results in higher wages, highest for the non-merging firms....

The international integration of regulated markets poses new challenges for regulatory policy. One question is the implications that the overall international regulatory regime will have for cross-border and/or domestic merger activity. In particular, do non-coordinated policies stimulate...

We analyze unionized firms’ incentives to outsource intermediate goods production to foreign (low-cost) subcontractors. Such outsourcing leads to increased wages for the remaining in-house production. We find that stronger unions, which implies higher domestic wages, reduce incentives for...

We find that trade unions have a rational incentive to oppose the adoption of labour-saving technology when labour demand is inelastic and unions care much for employment relative to wages. Trade liberalisation typically increases trade union technology opposition. These conclusions are reached...

The purpose of this article is to investigate the prospects for entry into an existing network in the telecommunication industry, and how public policy may promote a more competitive outcome. We apply a model that captures the fact that the incumbent has an installed base of loyal consumers,...

Many policy makers seem to prefer domestic alternatives to cross-broder mergers. Can such sentiments make sense? We contruct a model where cross-border mergers drive down union-set wages, where domestic mergers have larger non-labour cost synergies than international ones, and where policy...

We study a setting with search frictions in the marriage market and with incomplete contracting inside the family. Everyone prefers a partner that has high income and is a perfect emotional match, but compromises must often be struck. A high income earner may abstain from marrying a low-income...
