To buy or not to buy démi-tarif: the (quasi) irrelevance of reimbursement

In this short note, I show that an agent's decision to buy a travel discount card in not aff ected by whether she gets reimbursement of travel expenses and - in case of reimbursement - it is unaffected by the type of reimbursement (whether it is based on the discounted or on the full price).

Football Euro Cup results

In this joint short paper with Salvatore dell'Erba, we analyze the results of the Euro Cup from 1980 to 2004 in the round robin phase. We test whether victory in the first match and victory by an ample margin, have a significant impact on the probability of passing the round robin. As an extension, we analyze also whether it affects or not the probability of winning the tournament.

Optimal effort on a temporary job

In this paper I consider the optimal choice of on-the-job effort exerted by an individual who has a temporary job and would like to find another job with undetermined duration. This situation is quite common for new entrants in the labor market. They are often faced with the choice between exerting a lot of effort on the temporary job, in order to increase current earnings, or spending valuable time to look for a more stable job.
I build a two-period model that yields a simple solution for optimal effort as a function of variables with an immediate economic interpretation. I show that optimal effort on the temporary job is increasing in the responsiveness of wage to effort, and, perhaps more instructively, it is decreasing in the incidence of labor market regulations like minimum wage or occupation-specific minimum tariffs.
