This paper shows that search in the labour market has important effects on accumulation decisions. In a labour market characterized by search, employment contracts are naturally incomplete and this creates a wedge between the rates of return and marginal products of both human and physical...

This Paper studies the relationship between trade liberalization and informality. It is often claimed that increased foreign competition in developing countries leads to an expansion of the informal sector, defined as the sector that does not comply with labour market legislation. Using data...

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:...

This Paper develops a descriptive methodology for the analysis of wage growth of immigrants, based on human capital theory. The sources of the wage growth are: (i) the rise of the return to imported human capital; (ii) the impact of accumulated experience in the host country; and, (iii) the...

Becker's theory of human capital predicts that minimum wages should reduce training investments for affected workers, because they prevent these workers from taking wage cuts necessary to finance training. We show that when the assumption of perfectly competitive labour markets underlying this...

This study explains the evolution of wage inequality over the last 30 years and supports this explanation with evidence. At each level of schooling, a faster rate of technological progress weakens the link between schooling and work and increases the unknown needed to cope with during one's...

Swedish census data and tax records reveal an astonishing wage compression; the Swedish skill premium fell by more than 30 percent between 1970 and 1990 while the U.S. skill premium, after an initial decline in the 1970s, rose by 8-10 percent. Since then both skill premia have increased by...

This paper highlights analytical reasons why we believe trade and technology are linked to wage movements in general, and how we should organize our examination of the recent episode of wage and employment erosion in the OECD countries. We start with a graphic tour through the mechanics of...

This paper explores the interrelation between the degree of unemployment persistence and the unemployment-productivity trade-off. The analysis suggests that the more effective are structural labour market policies (designed to change labour market institutions and laws, such as job security...

We use a new sample of UK female identical twins to estimate private economic returns to education. We report findings in three areas. First, we use identical twins, to control for family effects and genetic ability bias, and the education reported by the other twin to control for schooling...
