While the employment effects of minimum wages are usually reported to be small (suggesting low substitutability between skill types), direct estimates suggest a much larger degree of substitutability. This paper argues that this paradox is largely due to a bias induced by the aggregation of...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) Index for industry concentration. This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

There has been much attention for the causes of the increase in wageinequality in the United States since the mid seventies. DiNardo,Fortin, and Lemieux (1996) showed that minimum wages can explain 25%. The present paper uses a more general approach requiring noassumptions on how minimum wages...

Though a lot of work has been done on the distribution of job tenures, we are still uncertain about its main determinants.In this paper, we stress random shocks to match productivity after the start of an employment relation.The specificity of investment makes hiring and separation decisions...

We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their skill. They face a trade-off between match quality and the cost of extended search. This trade-off differs between regions, because search is...

We argue in favour of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle between the stakeholders about the ultimate...
