We investigate what happens when the fiscal authorities do not react to rising public debt so that the unpleasant task of fiscal sustainability falls upon the Central Bank (CB). In particular, we explore whether the CB's bond purchases in the secondary market can restore stability and...

This paper, using a microfounded macroeconomic model that embeds the key features of the Greek economy, studies the efficacy of the various policy measures taken, at national and EU level, to cushion the economic effects of the pandemic shock. The paper attempts to give quantitative answers to...

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous...
