I study the consequences of heterogeneity of skills for the design of an optimal unemployment insurance, using a principal-agent set-up with a risk neutral insurer and infinitely lived risk averse agents. Agents, who are characterised by different productivities or skills, are employed by firms...

I estimate a life cycle model of consumption choice with unemployment risk. Employed individuals face the risk of losing their job. Unemployed agents receive job random offers of different quality, which they can accept or reject. Following the loss of a job and during unemployment, an agent’s...

In this paper, we raise the question of gender differences in the geographic mobility of young researchers. We try to answer to three main questions regarding the international mobility of young researchers during the post-doc period: Are there differences among genders? Does “family” have...

This paper considers a two-country world where the population in one country grows faster than the other, and investigates the implications of the addition of non-stationary population dynamics to a simple 2- commodity, 2-factor model of international trade within an overlapping- generations...

Since recent immigrants tend to earn less than natives, their relative labor market status has been adversely impacted by an increase in the return to labor market skills and widening wage inequality over the past two decades. To evaluate the magnitude of this effect, this study uses Social...

The equalization of profit rates across a multisector production economy subject to Nash bargaining over wages supports an industry wage structure like those that account for a large fraction of actual wage dispersion and a wage-wage-...-wage-profit surface on which the general profit rate can...

What determines the speed of the technology diffusion? What are the consequences of diffusion? This paper presents a model to address these questions. Skilled machine-users adopt a new technology first, while unskilled users wait until machines become more reliable and accessible. The quality...

This paper constructs an equilibrium model of entrepreneurial innovation where individuals differ in their attitude toward uncertainty. Unlike previous models of innovation, the firm-formation process is endogenous. An entrepreneur, who owns residual profits, utilizes an uncertain technology and...

This paper examines the nature of virtual teams and their place in the networked economy. It presents a framework for categorising virtual teams and argues that fundamental changes have taken place in the business environment which force people and organisations to operate in 'two spaces'...
