Politicians, the media, and the public express concern that immigrants depress wages by competing with native workers, but 30 years of empirical research provide little supporting evidence to this claim. Most studies for industrialized countries have found no effect on wages, on average, and...

I test some predictions of Gary Becker’s theory of taste discrimination regarding discrimination of foreigners by employers, co-workers and customers. I combine a 2% sample of the German working population and a 50% sample of German plants with low-level regional data, including the vote...

In spite of its predominant economic weight in developing countries, little is known about informal sector income dynamics vis-à-vis the formal sector. Some works have been done in this field using household surveys, but they only consider some emerging Latin American countries and a few...

In developing and transition economies as much as half the labor force works in the informal sector (or "shadow economy"). Informal firms congest infrastructure and other public services but do not contribute the taxes needed to finance them. Informal workers are unprotected against such...

Higher inequality reduces capital accumulation and increases the informal economy, which creates additional employment opportunities for low-skilled and deprived people. Despite this positive feedback, informality raises problems for public finances and biases official statistics, reducing the...

This paper is among the first to link internal migration and subjective well-being in developed countries. Economic theory predicts that individuals migrate towards urban agglomerations, if the potential gain in income is sufficient to cover costs. However, this narrow view cannot explain why...

Offshoring is often found to be associated with an increase of wage inequality between low- and high-skilled. This is interpreted as a relative decrease of low-skilled labor demand. However, the effect of offshoring on relative labor demand is ambiguous, since low-skilled workers may benefit...

An examination of regional unemployment rates reveals that there are vast differences which cannot be explained by different institutional. Our paper traces these differences in the regions labour market performance back to the regions specialisation in products that are more or less advanced in...

In this paper, I develop a simple model of spatial equilibrium to investigate theoretically what determines the sign and magnitude of ''local multipliers' (defined as elasticity of employment in the non-tradable sector with respect to increase in employment in the tradable sector). I estimate...

A key aspect of understanding how regions grow is the interplay between jobs in the tradable and jobs in the non-tradable sector. Jobs in the tradable sector supply the world market and can therefore move from region to region, but every region has a local demand for non-tradable goods and the...
