We consider a labor market search model where, by working longer hours, individuals acquire greater skills and thereby obtain better jobs. We show that job inequality, which leads to within-skill wage differences, gives incentives to work longer hours. By contrast, a higher probability of losing...

We study a labour market equilibrium model in which firms sign optimal long-term contracts with workers. Firms that are financially constrained offer an increasing wage profile: they pay lower wages today in exchange of higher wages once they become unconstrained and operate at a larger scale....

We consider a competitive equilibrium growth model where technological progress is embodied into new jobs that are assigned to workers of different skills. In every period workers decide whether to actively participate in the labor market and if so how many hours to work on the job. Balanced...

This Paper proposes a model of endogenous growth where innovating requires both researchers, who produce inventions, and entrepreneurs who implement them. As research and entrepreneurship compete in the allocation of aggregate resources, the relation between growth and research effort is...

Social contacts help workers to find jobs, but those jobs need not be in the occupations where workers are most productive. Hence social contacts can generate mismatch between a worker’s occupational choice and their comparative productive advantage. Thus economies with dense social networks...
