Non-western immigrants in Norway are shown to rely heavily on welfare transfers for several years after immigration. While refugee immigrants assimilate slightly out of welfare, other non-western immigrants assimilate rapidly into welfare. Re-migration is selective for both non-western and...

In this paper the effects on aggregate consumption of changes in the age distribution of the population are analysed empirically. Economic theories predict that age influences individuals’ saving and consumption behaviour. Despite this, age structure effects are rarely controlled for in...

Several studies have demonstrated that individual contributions to public goods are increasing in others’ contributions. The underlying causes for this, however, are not yet fully understood. We present a model of duty-orientation in which moral responsibility is learned through observations...

In March 2003 the Norwegian government implemented yardstick based price regulation schemes on a selection of drugs experiencing generic competition. The retail price cap, termed “index price”, on a drug (chemical substance) was set equal to the average of the three lowest producer prices on...

We estimate labor supply when tax evasion is an option, using a discrete choice model on pooled Norwegian survey data from 1980 and 2001. Direct labor supply elasticities, conditional on sectors, are in the range of 0.2-0.4. The elasticities are higher for work that is not registered for...

A structural model for retirement and employment based on a flexible, parametric utility function is developed. The model requires only cross section data and is estimated on survey data for Italy and register data for Norway. The estimates indicate that the preference structure among...

Individual long run effects of a labour market training programme targeted at unemployed adults are evaluated by comparing mean post-training earnings for matched samples of participants and non-participants. Average training effects on the trained are positive and persistent over the...

Regional colleges in Norway were reorganised in 1994 with the purpose of promoting efficiency and productivity. This is the first effort of checking what actually has happened afterwards with efficiency and productivity. DEA and Malmquist index approaches are used. Data for three years, 1994,...
