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,...

I study the effect of voters with a group-based social conscience. Voters then care more about the well-being of those belonging to their own group than the rest of the population. Within a model of political tax determination, both fractionalization and group antagonism reduce the support for...

In the period from 1970 to 2002, Norwegian women moved out of the home and into the paid labour market. The paper investigates the e®ect of this social change on women's economic position and on individual income in-equality. It argues that the distribution of individual incomes is of equal...

This paper explores the existence of downward nominal wage rigidity (DNWR) in 19 OECD countries, over the period 1973–1999, using data for hourly nominal wages at industry level. Based on a novel nonparametric statistical method, which allows for country and year specific variation in both the...

This paper introduces two composite indices of globalization. The first is based on the Kearney/Foreign Policy magazine and the second is obtained from principal component analysis. They indicate the level of globalization and show how globalization has developed over time for different...
