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 currency crises of the 1990s all exhibit a divergence of the nominal and the real exchange rate together with an increase in the negative current account. The nominal rate does not reflect inflation differences fully and the ensuing real appreciation leads to a negative current account. This...

The stability pact is intended to bind the hands of national fiscal policy with respect to debt and thus protect the euro as a common currency. To what extent the value of money is stable depends on the solidity of the government’s finances. To weaken the pact will imply a loss of confidence...

This paper proposes an approach for estimating the uncertainty associated with model-based macroeconomic forecasts. We argue that estimated forecast intervals should account for the uncertainty arising from selecting the specification of an empirical forecasting model from the sample data. To...

Germany has had an extremely low growth performance since 1995. The paper looks at the long-run reasons for this loss of economic dynamics besides German unification: These include leaving labor idle, a declining share of investment in GDP, a weaker innovative activity, an ineffective system for...

How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually...

Sovereign governments owe debt to many foreign creditors and can choose which creditors to favor when making payments. This paper documents the de facto seniority structure of sovereign debt using new data on defaults (missed payments or arrears) and creditor losses in debt restructuring...

Sovereign defaults are bad news for investors and debtor countries, in particular if a default becomes messy and protracted. Why are some debt crises resolved quickly, in a matter of months, while others take many years to settle? This paper studies the duration of sovereign debt crises based on...

We study sovereign external debt crises over the past 200 years, with a focus on creditor losses, or "haircuts". Our sample covers 327 sovereign debt restructurings with external private creditors over 205 default spells since 1815. Creditor losses vary widely (from none to 100%), but the...

Sovereign debt crises are difficult to solve. This paper studies the "holdout problem", meaning the risk that creditors refuse to participate in a debt restructuring. We document a large variation in holdout rates, based on a comprehensive new dataset of 23 bond restructurings with external...
