Research on entrepreneurship often uses information on self-employment to proxy for business creation and innovative behaviour. However, little evidence has been collected on the link between these measures. In this paper, we use data from the UK Labour Force Survey (LFS) combined with data from...

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...

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

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...

The skill gap in geographical mobility is entirely driven by workers who report moving for a new job. A natural explanation lies in the large expected surplus accruing to skilled job matches. Just as large surpluses ease the frictions which impede job search in general, they also help overcome...

The Beveridge curve depicts a negative relationship between unemployed workers and job vacancies, a robust finding across countries. The position of the economy on the curve gives an idea as to the state of the labour market. The modern underlying theory is the search and matching model, with...

In 1996 the UK made major changes to its welfare system for the support of the unemployed with the introduction of the Jobseeker’s Allowance. This tightened the work search requirements needed for eligibility for benefit. It resulted in large flows out of claimant status, but, this paper...

We use a simple job search model to explain the doubling of mean hourly earnings of white males, and the five-fold increase in their variance, during the first 18 years of labor market experience. For this purpose we embody minimum wage regulations and imperfect compliance in a job search model...

Reduced- form tests of scale effects in markets with search, run when aggregate matching functions are estimated, may miss important scale effects at the micro level, because of the reactions of job searchers. A semi-structural model is developed and estimated on a British sample, testing for...

Reduced-form tests of scale effects in markets with search, based on aggregate matching functions, may miss important scale effects at the micro level, because of the reactions of job searchers. We estimate a semi-structural model on a British sample of unemployed people, testing for scale...
