Given that taxes are always distorting and/or that public spendingis not always beneficial for every income group, the key issue of this thesis is to look forthe least distorting tax mix and/or Pareto improving spending reforms. In this context, thethesis deals with three debated topics of the policy and academic agenda.101 p.CC BY: Attribution alone 4.0https://creativecommons.org/licenses/by/4.0/Fiscal policyPublic financePublic spendingComputational macroeconomicsText
