This paper contributes to the ongoing debate on the relationship between austerity measures and economic growth. We propose a general equilibrium model where (i ) agents have recursive preferences; (ii ) economic growth is endogenously driven by investments in R&D; (iii ) the government is committed to a zero-deficit policy and finances public expenditures by means of a combination of labor taxes and R&D taxes. We find that austerity measures that rely on reducing resources available to the R&D sector depress economic growth both in the short-and long-run. High debt EU members are currently implementing austerity measures based on higher taxes and/or lower investments in the R&D sector. This casts some doubts on the real ability of these countries to grow over the next years.Keywords: Austerity Measures, Fiscal Policy, Endogenous Growth, R&D JEL Codes: G12, G15 * All authors are at the Research Center SAFE, Goethe University Frankfurt, Grüneburgplatz 1, 60323 Frankfurt, Germany.Corresponding author: Patrick Grüning, gruening@safe.uni-frankfurt.de, +49 (0) 69-798-30086.
