In 2007 all ECB publications feature a motif taken from the €20 banknote. Despite intense calls for safeguarding public investment in Europe, public investment expenditure, when measured in relation to GDP, has steadily fallen in the last three decades, evoking fears that economic activity may be correspondingly negatively a¤ected. At the same time, however, public consumption in the EU-12 countries has trended up. In this paper, we provide a macroeconomic assessment of the observed change in the composition of public spending in the euro area in a medium-scale twocountry dynamic stochastic general equilibrium (DSGE) model. First, we analyze the channels through which, both temporary and permanent public investment shocks generate larger …scal multipliers than exogenous increases in public consumption. Furthermore, we quantify the negative impact of a change in …scal stance, characterized by a permanent rise in public consumption and a permanent fall in public investment, keeping thereby the overall level of public spending constant. The key message of the paper is that calls for reversing the observed trend in the composition of public spending are well justi…ed.

ECB Working Paper Series No 795 August 2007Non-Technical Summary This paper analyzes the macroeconomic e¤ects of the observed change in the composition of public spending in the European Union (EU) since the 1970s-characterized by a continuous fall in public investment and a corresponding rise in public consumption when measured as shares of GDP-and concludes that calls for safeguarding public investment are well justi…ed.The paper is motivated by recent debates in the EU about the relative e¤ectiveness of public consumption versus public investment as demand management tools. In particular, the debate has focused on the veracity of the underlying hypothesis that public investment is a relatively more potent instrument of …scal policy than public consumption. If this were true-a notion that seems to be well espoused by the European Commission-then …scal consolidation strategies in EU countries should preferably not be implemented by cutting back on public investment because the latter generates higher rates of return than projects related to public consumption.Although there is a substantial empirical literature that attempt to identify the sources of these developments, there is still a lack of understanding of the nature and the impact of a change in the composition of public spending. Furthermore, the empirical literature is inconclusive, which type of public spending has a stronger impact on macroeconomic activity. In that sense, the paper attempts to …ll this void by providing a comparative qualitative and quantitative analysis of the relative strength of public consumption and public investment expen...
