摘要

This paper investigates how occupational tasks contribute to changes in the Italian wage structure over 2009–2019. I match employee wages from the Italian Labour Force Survey with occupation-level task indicators from the Italian Sample Survey of Professions and construct a broad set of task measures (interpersonal/social, abstract/cognitive, manual, routine-cognitive, and routine-manual). Using unconditional quantile regressions and RIF-based decompositions, I separate composition effects from wage-structure (returns) effects along the wage distribution. I document a modest decline in hourly wage inequality during the decade, also among full-time workers. Decomposition results show that compositional shifts, most notably rising education and changes in the task content of employment, tend to increase dispersion. At the same time, wage-structure effects dominate and compress inequality, with a prominent role for sectoral wage premia. Subperiod decompositions (2009–2013 vs. 2014–2019) and item-level robustness checks confirm the main qualitative findings.
