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...

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...

This paper presents both theoretical analysis and econometric evidence for the United States, Great Britain and Norway on the extent to which hourly wages of different groups of workers are sensitive to local labour market conditions. We focus on differences by union status. Our theoretical...

Labour market outcomes of immigrants and natives are affected differently by macroeconomic conditions. In particular, we show that earnings of immigrants in Norway from outside the OECD area are more sensitive to local labour market conditions than are earnings of natives. Failure to account for...

We provide evidence on wage profiles of immigrants using CPS data from 1979 to 2001, taking into account that changes in labor market conditions impact natives and immigrants differently. High rates of immigrant wage assimilation in general, and relatively high wages of immigrant cohorts that...

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...

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...

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...
