Paper Title
Is there a Wage Premium or a Wage Penalty for Part-Time Contracts? New Evidence from Italy

Abstract
This paper investigates the full-time/part-time wage gap by using matched employer-employee data on the entire population of workers and firms in Italy over a 32-year period. Relying on regression models that control for worker, firm, and match fixed effects, we find that part-time work attracts a wage premium compared to full-time work. This finding, coupled with the detrimental effect of part-time work on productivity documented by Devicienti et al. [1], explains why firms are often unwilling to concede part-time positions to employees asking for them.
