Microsimulation Tools for the Evaluation of Fiscal Policy Reforms at the Banco De Espaaa

This paper presents the microsimulation models developed at the Banco de Espana for the study of fiscal reforms, describing the tool used to evaluate changes in the Spanish personal income tax and also the one for the value added tax and excise duties. In both cases the structure, data and output of the model are detailed and its capabilities are illustrated using simple examples of hypothetical tax reforms, presented only to illustrate the use of these simulation tools.
