[eng] The main objective of this project is to introduce the update made to
Gladhispania model. Thanks to this update the model is able to simulate
Spanish Personal Income Tax for the year 2014 and the possible effects of a
hypothetical reform in households’ disposable income and income
redistribution.
The data used for this microsimulation model is the Survey of Income and
Living Conditions, provided by the Spanish National Institute of Statistics.
In order to test the utility of this microsimulator it was simulated the scenario of
the year 2014 and a theoretical reform. The aim is twofold. First, testing if its
results were adjusted to 2014’s reality. Second, creating an alternative tax
reform that improved equality and a more redistributive system without
modifying tax revenue.
The results of these simulations were really productive and the objectives were
achieved: the microsimulation model was able to reproduce 2014’s scenario
and the proposed tax reform increased redistribution among individuals.
