The purpose of this final thesis paper is to empirically evaluate macroeconomic spillover effects of government spending shocks in the euro area. The methodological approach to the thesis consists of two parts, where quarterly data on government consumption and gross domestic product of selected euro area countries are used. The first part is the identification of government spending using the SVAR model and restrictions that are introduced with the assumption of the lag existence during the decision and implementation of a new fiscal policy measure. The second part is the spillover index, in which the structural shocks of the fiscal variable are used as endogenous variables, for the purpose of calculating total spillovers, directional spillovers and dynamic spillovers. The results of the empirical analysis for the period from the first quarter of 1995 to the first quarter of 2023 shows the existence of a feedback loop between shock transmitters and receivers, with each country having only a smaller subset of countries with strong spillover bonds. Spillovers are higher during periods of crises, and they reach their highest level at the beginning of the pandemic, which also affects a sudden change in the direction of pairwise net spillovers. Research limitation is the observation of only selected euro area countries due to short availability of data. This final thesis and research results are important so that policy makers, when deciding on a new measure, can take into account the externalities that the new measures can transmit to other countries. This is also the first paper that uses the spillover index methodology for the analysis of fiscal policy spillovers.
