With NATO members expected to reach2% of GDP and discussions underway to increase targets to 5% by 2035, this paper examines the possiblemacroeconomic consequences of such rearmament using two complementary approaches. First, using anannual panel dataset covering 27 EU countries over the period 1989–2023, we show that past national defensespending has stimulated economic activity in the short term, and entailed sizable cross-border spillovers.Importantly, we find that spending multipliers varied considerably across countries and over time: they tendedto be larger when import intensity is low, fiscal space (captured by sovereign yields spread) is ample, and RECOMMENDED CITATION:Davide Furceri, Pedro Juarros, Saurabh Mishra, Anh Dinh Minh Nguyen, AnaSofia Pessoa, and Alexandre Sollaci. “Macroeconomic Impacts of EU Defense Spending”.
