Does capital-embodied technological change play an important role in shaping labour market inequalities? This Paper addresses the question in a model with vintage capital and search/matching frictions where costly capital investment leads to large heterogeneity in productivity among vacancies in...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

Firing costs due to employment protection legislation have two separate dimensions: a transfer from the firm to the worker to be laid off and a tax paid outside the firm-worker pair. We document that quantitatively transfers are a much larger component than taxes. Nevertheless, to avoid the...

We examine how technological change affects wage inequality and unemployment in a calibrated model of matching frictions in the labour market. We distinguish between two polar cases studied in the literature: a ‘creative destruction’ economy where new machines enter chiefly through new...

Employment Protection rules have two separate dimensions: a transfer from the firm to the worker to be laid off and a tax paid outside the firm-worker pair. It is well established that with full wage flexibility statutory severance payments (pure transfers) between employers and dismissed...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by JM Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

The aim of this paper is to better understand the impact of unemployment on the design of Pay-As-You-Go pension systems, in the context of population aging. We consider a model in which people differ according to age and face in every period a given probability of becoming unemployed. We first...

We propose a new econometric estimation method for analysing the probability of leaving un-employment using uncompleted spells from repeated cross-section data, which can be especially useful when panel data are not available. The proposed method-of-moments-based estimator has two important...

In this Paper, I analyse the pros and cons of implementing structural reforms of the labour market in booms versus recessions, in light of considerations of social efficiency, political viability, and macroeconomic fine-tuning. While the optimal timing of a reform depends on the relative...

Theoretical predictions of the impact of TFP growth on unemployment are ambiguous, and depend on the extent to which new technology is embodied in new jobs. We evaluate a model with embodied and disembodied technology, capitalization, and creative destruction effects by estimating the impact of...
