Estimating the currency union effect on trade has been a contentious topic, with a wide range of estimates on the true size of gains. One fundamental issue underlying many estimates is the lack of a accurate control group against which to compare outcomes, making it hard to understand the degree...

In this paper we rely on techniques recently developed by Bai and Ng (2004a) to estimate common euro-area stationary and non-stationary factors using a large-scale dynamic factor model. We find that euro-area economies share four non-stationary factors or trends and one stationary factor. By...

This paper employs two established macroeconomic models to show that fiscal policy in the euro area can help monetary policy in reducing inflation. Specifically, a fiscal consolidation of 1 percent of GDP for two years and 0.5 percent in the third year across the euro area would ease the policy...

No matter its source, financial- or policy-related, uncertainty can feed onto itself, concealing its true origin and leading to identification challenges in empirical applications. We add to the existing stock of analytical methods able to disentangle among various types of uncertainty shocks,...

We study the design of optimal monetary policy (Ramsey policies) in a model with sticky prices and unionized labour markets. Collective wage bargaining and unions monopoly power tend to dampen wage fluctuations and to amplify employment fluctuations relatively to a DNK model with walrasian...

The implications of monetary unification for fiscal policies are discussed. The roles of nominal exchange rate flexibility in the presence of asymmetric national shocks and nominal price rigidities as an automatic stabilizer and source of disturbances to real economic performance are reviewed....

This paper addresses arguments that a system of fiscal insurance between member states of the European Union is needed to act in replacement of nominal exchange rate flexibility as an automatic stabilizer under monetary union. Many authors have argued or assumed that asymmetric real...

Data show that sovereign risk reduces liquidity, increases funding cost and risk of banks highly exposed to it. I build a model that rationalizes this fact. Banks act as delegated monitors and invest in risky projects and in risky sovereign bonds. As investors hear rumors of increased sovereign...
