Real Effective Exchange Rates Determinants and Growth : Lessons from Italian Regions

In this paper we analyse the price competitiveness of the Italian regions by computing the Real Effective Exchange Rate (REER) for each region, deflated by CPI and vis-à-vis the main partner countries. We use them to look for the medium-term determinants, finding significant heterogeneities in the role of government consumption and investment expenditure. Government consumption has an extremely negative effect on competitiveness in North-Eastern Italy, Southern Italy and Lazio. Investment plays a negative role especially in the North-West, while it can be positive for competitiveness in Lazio and Southern Italy. We also find that the transfer theory does not necessarily hold and it even behaves in the opposite direction in case of North-Eastern Italy and Lazio. Lastly, we show that an increase in the regional price competitiveness influences regional growth positively only in the long run and spillovers may play a role
