I examine the dynamic evolutions of unemployment, hours of work and the service share since the war in the United States and Europe. The theoretical model brings together all three and emphasizes technological growth. Computations show that the very low unemployment in Europe in the 1960s was...

This paper considers a real business cycle model with search frictions in the labor market and labor supply which is elastic along the participation margin. Previous authors have found that such models generate counterfactually procyclical unemployment and a positively-sloped Beveridge curve....

This paper uses micro data from the 1980, 1991 and 2000 population censuses to investigate the role of changes in the industry mix in accounting for the differential trends in the incidence of child work (ages 10-15) across Brazilian states. We find that exogenous compositional changes account...

The phenomenon of 'job polarisation' is increasing inequality as the labour market splits into high- and low-wage work. According to Alan Manning, who coined the term a decade ago, we cannot ignore job polarisation - but with sensible policies, we can manage it. Aiming for greater equality in...

Job polarisation has had strong effects on US workers' relative wages, according to research by Michael Boehm. His study examines whether the decline in manufacturing and clerical jobs has been responsible for the lagging wages of middle-skill workers in the United States. Comparing the...

This paper shows the employment structure of 16 European countries has been polarizing in recent years with the employment shares of managers, professionals and low-paid personal services workers increasing at the expense of the employment shares of middling manufacturing and routine office...

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 is little doubt that technology has had the most profound effect on altering the tasks that wehumans do in our jobs. Economists have long speculated on how technical change affects boththe absolute demand for labour as a whole and the relative demands for different types of labour.In...

This paper explores a newly-available panel data set merging balance sheet and international trade transaction data for Belgium. Both imports and exports appear to be highly concentrated among few firms and seem to have become more so over time. Focusing on manufacturing, we find that facts...

This paper shows, using data from both the US and the UK, that average plant size is larger in denser markets. However, many popular theories of agglomeration - spillovers, cost advantages and improved match quality - predict that establishments should be smaller in cities. The paper proposes a...
