In a circular matching model, firms rank their applicants and pick the best suited one. Job creation appears to lower the average output. As firms do not internalize this effect, jobs are too many in the laissez-faire equilibrium under the Hosios condition. Due to similar externalities firms'...

In this paper, training, which is seen as a way to reduce the mismatch between workers and jobs, takes place on the job. We show that a general rise in unemployment lowers the probability of on-the-job training by reducing the mismatch. We then close the model by assuming free-entry and study...

The efficiency of educational choices is studied in a search-matching model where individuals face a tradeoff: acquiring formal education or learning while on the job. When their education effort is successful, newcomers directly obtain a high-skill job; otherwise, they begin with a low-skill...

This paper provides an analysis of the social consequences of people seeking to keep up with the Joneses. All individuals attempt to reach a higher rank than the Joneses, including the Joneses themselves. This attitude gives rise to an equilibrium in which all individuals have equal utilities...

Dans un contexte de chômage élevé, les grandes villes connaissent une ségrégation urbaine qui conduit certains habitants à s'installer dans des zones très éloignées du centre actif de la ville. Tant le manque d'emploi que la fracture spatiale créent des problèmes sociaux tels que les...

This paper reexamines the efficiency of participation with heterogeneous workers in a search-matching model with bargained wages and free entry. Assuming that firms hire their best applicants, we state that participation is insufficient whatever workers' bargaining strengths. The reason for this...
