In this research, we analyse the use of fiscal expenditure as an instrument of fiscal consolidation policy. Portugal was subject to the financial assistance programme (PAEF) articulated with the IMF, the European Commission and the European Central Bank between 2010 and 2014. The objective is to analyse the evolution of fiscal expenditure in the following four years, after the end of that term programme, that is, between 2015-2018. The outcome is to know if the policy of reducing fiscal expenditure implemented in the years in which the programme was in force (2010-2014), continued into the following four years. We compared this evolution with the evolution of direct expenditure, based on two main axes: economic expenditure and social expenditure. The data collection technique is used through document research, and the data obtained was from information provided by national, European statistical authorities and secondary sources of information. It is concluded that, in the 2014-2018 period, the increase in public revenue, due to the decrease in tax expenditure, did not evolve consistently. In 2014-2018, direct public expenditure did not follow the same pattern as in the previous years of 2011-2014, given the functional equivalence of the two types of expenditure. Finally, to observe the relationship between the level of fiscal consolidation, carried out between the years 2010 and 2018, and the behaviour of tax revenue and expenditure, the Scheffé test was performed on the averages of the variables Total Revenue and Expenditure, and Tax Revenue and Expenditure. This was applied in order to observe if the averages of the variables are significantly relevant for the level of fiscal consolidation or if there are other variables, equally important, that were not taken into account in the study, but that had a preponderant role (such as the economic context). We have to statistically conclude that both the revenue and expenditure averages and the percentage averages are not all equal, as they are, in fact, all different between the groups analysed. In order to clarify if the differences in revenue and expenditure and in the respective percentages are statistically significant or if, on the contrary, they are merely eventual, we previously verified their applicability through the assumptions of normality and homoscedasticity of each of the data sets, using the ANOVA test (Fisher, 1918). We observed that for both the amounts of revenue and expenditure, as well as the percentages, the p-value observed in the ANOVA test was equal to 0.000 (i.e. less than 0.050), implying the rejection of the null hypotheses and the acceptance of the alternative hypotheses, according to which the average values of the amounts of revenue and expenditure, and the average values of the percentages are not all equal. The general conclusion is that there was budget consolidation, but this must have been due to other factors, such as the economic environment, since there is no direct relationship between revenue, fiscal expenditure and budget consolidation in any of the periods studied.

A crise econômica que atingiu muitos países da OCDE, aliada ao excesso de despesa pública, aos elevados níveis de dívida pública acumulada e à incapacidade de os Estados conseguirem mais receita fiscal obrigou muitos, particularmente na Europa, fez com que fossem adotadas estratégias de consolidação das suas contas públicas a longo prazo. Esta pesquisa teve por objetivo analisar em que medida a despesa fiscal contribuiu para o esforço de consolidação orçamental. A análise empírica dos dados seguiu uma natureza predominantemente quantitativa, assente na coleta dos dados e no estudo da relação entre eles. Conclui que a redução da despesa fiscal contribuiu para o aumento da receita pública e que ela apresenta um padrão comportamental semelhante ao da despesa direta. Conclui-se ainda que a integração da despesa fiscal na despesa pública fornece uma ideia mais rigorosa da medida de intervenção do Estado na economia e na sociedade e uma maior transparência na otimização da combinação de ambas no âmbito das escolhas orçamentais.
