This paper aims to measure and evaluate the redistributive effect of transfers and distribution of financial resources between common regime Spanish Autonomous Communities (ACs) for different models of regional funding, from 1987 to 2010. The key results are that the transfers have an important redistributive effect that reduces revenue inequality of the ACs. This effect began to be very different between the ACs 151 and 143, although it has been converging according as the latter equate their spending powers with the first. Also, we see some stability in the first models that clearly breaks with the 2002-2008 model.
