According to the fiscal theory of the price level (FTPL), the interactions between monetary and fiscal policies with governments facing the possibility to act in a non-Ricardian manner make the general price level be fully determined. Here, depending on the expectations framework, we show to...

This paper quantifies the effects on welfare of misspecified monetary policy objectives in a stylized DSGE model. We show that using inappropriate objectives generates relatively large welfare costs. When expressed in terms of ‘consumption equivalent’ units, these costs correspond to...

This paper analyses the effects of transitory increases in government spending when public debt is used as liquidity by the private sector. Aggregate shocks are introduced into an incomplete-market economy where heterogenous, infitely-lived households face occasionally binding borrowing...

When countries decide to coordinate and form a coalition, an outsider country can take advantage of the situation and gain more than an insider, hence creating a free-rider problem that could threaten the stability of the coalition. But as far as the Euro zone is concerned, the emphasis put on...
