Abstract
Since 2019, Spain has experienced one of the largest minimum-wage increases among developed economies, providing a valuable natural experiment to evaluate the effects of this policy. This article aims to conduct a systematic review using the PRISMA 2020 methodology to compile all available evidence from the Spanish case —including hard-to-access studies not published in academic journals— and to critically discuss the methodologies employed and the results obtained. The results reveal an increase in the lowest wages and less wage inequality, without substantial adverse effects on employment.
