Over the last two decades, earnings in the United States increased at the top and at the bottom of the wage distribution but not in the middle - the intensely debated middle class squeeze. At the same time there was a substantial decline of employment in middle-skill production and clerical...

There has been a remarkable increase in wage inequality in the US, UK and many other countries over the past three decades. A significant part of this appears to be within observable groups (such as age-gender-skill cells). A generally untested implication of many theories rationalizing the...

This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

We analyze the performance outcomes of National Hockey League (NHL) players over 18 seasons (1990-1991 to 2007-2008) as a function of the demographic conditions into which they were born. We have three main findings. First, larger birth cohorts substantially affect careers. A player born into a...

In this paper we adopt a theory of class positions based on employment relations to assess what implications individuals¿ class positions have for their economic life. In particular we consider economic security (the risk of unemployment), economic stability (the variability component in...

Labor market institutions, via their effect on the wage structure, affect the investment decisions of firms in labor markets with frictions. This observation helps explain rising wage inequality in the US, but a relatively stable wage structure in Europe in the 1980s. These different trends are...

This paper assesses the potential of `workplace training'' with reference to German Apprenticeship. When occupational matching is important, we derive conditions under which firms provide `optimal'' training packages. Since the German system broadly meets these conditions, we evaluate the...

UK government policy encourages mothers of young children in low-income families to enter or return to work, via tax credit subsidies and support for childcare. Maternal employment is seen a central plank in the campaign against child poverty, both because it raises income immediately and...

In this paper we estimate the sorting effects of university degree class on initial labor market outcomes using a regression discontinuity design that exploits institutional rules governing the award of degrees. Consistent with anecdotal evidence, we find sizeable and significant effects for...

An increase over time in the proportion of young people obtaining a degree is likely to impact on the relative ability compositions (i) of graduates and non-graduates and (ii) across graduates with different classes of degree award. In a signalling framework, we examine the implications of this...
