Efficiency of Demand Shocks in Order to Reduce Current Account Imbalances in the EMU

With the current European sovereign public debt crisis and current account imbalances difficulties in the EMU, many papers now underline that the problem of the European construction is its lack of institutional framework and common economic governance necessary to make a monetary union viable. According to these papers, the solution would lie in a stronger economic cooperation, with the Northern European countries contributing to lighten the burden of the Southern debtor countries. In this context, our model shows that a symmetric positive demand shock in the EMU could only slightly reduce the external indebtedness of the Southern European countries but would efficiently reduce their public debt levels. To the contrary, an asymmetric positive demand shock in the creditor Northern European countries (e.g., an increase in German wages) could reduce the current account deficits of the Southern European countries, in particular for countries with the highest openness to trade. Nevertheless, it would worsen the indebtedness levels, and it would also increase the recessionary risks in these countries.
