This paper uses quantile regressions to describe the conditional wage distribution in Portugal and its evolution over the 1980s as well as the implications for increased wage inequality. We find that, although returns to schooling are positive at all quantiles, education is relatively more valued for highly paid jobs. Consequently, schooling has a positive impact on wage inequality. Moreover, this tendency has sharpened over the period. We also find that most of the estimated change in wage inequality was due to changes in the distribution of the worker's attributes, rather than to increased inequality within a particular type of worker.
