Why do people in rich countries not transfer more of their income to people in the world's poorest countries? To study this question and the relative importance of needs, entitlements, and nationality in people's social preferences, we conducted a real effort fairness experiment where people in...

Labour-market polarization is characterized by increased employment in occupations at the top but also at the bottom of the skills and wage distributions, followed by a relative decline in 'middling' occupations. This paper documents a polarization trend also in the Nordic labour markets and...

The paper reports the first experimental study on people's fairness views on extreme income inequalities arising from winner-take-all reward structures. We find that the majority of participants consider extreme income inequality generated in winner-take-all situations as fair, independent of...

We report the results of a randomized controlled trial testing whether incentivizing physical exercise improves the academic performance of college students. As expected, the intervention increases physical activity. The main result is that it generates a strong and significant improvement in...

Based on matched employer-employee data from Norway, we analyze the effects of worker displacement in 1986-1987 on their children's earnings in 1999-2001. Using displacement of fathers to indicate an exogenous earnings shock we seek to identify whether family resources have a direct effect on...

Using Norwegian intergenerational data with a substantial part of the life-cycle earnings of children and almost the entire life-cycle earnings for their fathers, we present new estimates of intergenerational mobility. Extending the length of the fathers' earnings windows from 5 to 30 years...

This paper examines the impact of performance-related pay on wage differentials within firms. Our theoretical framework predicts that, compared to a fixed pay system, pay schemes based on individual output increase within-firm wage inequality, while group-based bonuses have minor effects on wage...

In this paper we analyse early retirement pathways for Norwegian male and female workers. We apply a multinomial logit model to a data set covering more than 10 500 employees, ages 56-61, in 1989. The aim is to analyse the transition to different destinations, i.e. disability pension,...
