- Part-time job and wage penalty trend among italian womenPublication . Sciulli, Dario; Parodi, GiulianaThis paper studies the evolution of full-time/part-time wage differential among Italian women for the period 1993-2004 by adopting an extension of Heckman procedure. For each wave under analysis, we estimate a four-outcome employment status model in the first step, and full-time and part-time wage equations corrected for selectivity in the second step. Our results show a decreasing trend of part-time wage penalty across waves. Using Oaxaca decomposition technique we find that part-time workers are constantly, but in a decreasing way, over-paid according to observable characteristics. This is because, Interestingly, discrimination and selection components (the adjusted differential) take, in turns, similar and opposite values contributing to create an observed overall wage premium.
