Summary
Since the 2008 crisis, public investment as a proportion of GDP has declined significantly both in Spain and in other euro area countries. That trend recently came to an end, given that public expenditure has been bolstered in response to the health crisis and will be further reinforced in Spain by the EU funds received under the Next Generation EU (NGEU) programme. Public investment’s effect on economic activity will depend, among other factors, on its impact on private investment, the sign of which is, a priori, ambiguous. This article assesses the short-term relationship between public and private investment using the structural vector autoregressive (SVAR) approach. The results suggest that, on average, increases in public investment in Spain tend to generate a positive impact on private investment. In particular, an increase of 1% in public investment would be associated with an equivalent increase in private investment in the short term. This finding underscores the important role that NGEU could play in economic developments in the years ahead.
