This paper surveys major empirical regularities concerning changes in earnings inequality in Europe and the US over the past 25 years. Next, it indicates which of these regularities can be explained within the competitive demand-supply framework of analysis and what is left unexplained. Finally,...

We analyze the distribution and concentration of market incomes in Germany in the period 1992 to 2001 on the basis of an integrated data set of individual tax returns and the German Socio-Economic Panel. The unique feature of this integrated data set is that it encompasses the whole spectrum of...

In this Paper, we analyse the extent to which market forces create an incentive for cloning human beings. We show that a market for cloning arises if a large enough fraction of the clone's income can be appropriated by its model. Only people with the highest ability are cloned, while people at...

This Paper demonstrates that women search longer for their first or second husband in cities with higher male wage inequality, and analyses several explanations for this result. A causal link is established by showing that the results are robust to the inclusion of city fixed-effects and...

This Paper examines the education literature through the lens of sorting. It argues that how individuals sort across neighborhoods, schools and households (spouses), can have important consequences for the acquisition of human capital and inequality. It discusses the implications of different...

A basic tenet of economic science is that productivity growth is the source of growth in real income per capita. But our results raise doubts by creating a direct link between macro productivity growth and the micro evolution of the income distribution. We show that over the entire period...

The ‘fractal’ nature of the rise in earnings dispersion is one of its key features and remains a puzzle. This paper offers a new perspective on the causes of changes in earnings dispersion, focusing on the role of labour reallocation. Once we drop the assumption that all firms pay a given...

Recent empirical contributions in labor economics suggest that individual firms face upward sloping labor supplies. We rationalize this by assuming that idiosyncratic non-pecuniary conditions interact with money wages in workers’ decisions to work for specific firms. Likewise, firms supply...

Switzerland has experienced a substantial influx of immigrants over the 50 years since World War II, to the extent that it now has one of the highest share of foreigners in population among OECD countries. This paper analyses Switzerland’s experience of migration, centring on two main issues:...
