Resumo(s)
Using a remarkable matched employer-employee dataset, this thesis investigates how wage
dispersion evolved in Portugal and whose components contributed more to this variation,
highlighting the impact of peer effects in both individual wages and wage inequality. A regression
model with high dimensional fixed effects is used. The results show that, contrary
to the case of Germany, wage dispersion in Portugal has decreased over the last decade.
Person effects are the main contributors, with its contribution rising over time, contrasting
with the declining role of firm effects. The role of peer effects in wage dispersion ranges
between 4.2% and 6.6%, with a one standard deviation increase impacting on individual
wages with that same magnitude.
