- We lay out an empirical and a theoretical model to analyze the effects of non-fundamental exchange rate volatility on economic activity and welfare. In the first part of the paper, the GARCH-SVARmodel is applied to measure empirically the effect of the conditional exogenous exchange rate volatility on the conditional mean of the endogenous variables in our open economy VAR. Our results for Canada, Germany and UK indicate that the effects of exchange rate uncertainty are small empirically. In the second part, we investigate the effect of non-fundamental exchange rate volatility in a stochastic open economy model. The second order approximation method of Sims  is applied to the model equilibrium conditions. We show that in a model with habit persistence, even non-fundamental exchange rate volatility that generate only small variation in the unconditional mean of the variables might induce economically significant welfare changes.

- 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 affected. 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 two-country dynamic stochastic general equilibrium (DSGE) model. First, we analyze the channels through which, both temporary and permanent public investment shocks generate larger fiscal multipliers than exogenous increases in public consumption. Furthermore, we quantify the negative impact of a change in fiscal 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 justifed.
