The impulse responses are constructed to analyze the impact of government spending measures on output, in a model where confidence is not included, to isolate the direct effect of government expenditure on output, and in a model with confidence, to account for an indirect effect through confidence. Overall, the findings suggest that neither consumer confidence nor business confidence play a crucial role in the propagation of public spending shocks into output.engConsumer and business confidenceGovernment expenditureOutputPortugalmaster thesis201716712
