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...

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...

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 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...

We review the literature on geoeconomics, defined as the field of study that links economics and geopolitics (power rivalry). We describe what geoeconomics is and which questions it addresses, focusing on five main subfields. First, the use of geoeconomic policy tools such as sanctions and...

Pecking order models of international finance suggest that countries should become less reliant on international bank lending as they develop. Reduced information costs are one of the factors behind this trend towards disintermediation. This paper presents a simple model on the choice between...

Changes in foreign asset holdings are one channel through which agents adjust to macroeconomic shocks. In this paper, we test whether foreign bank assets change as a result of domestic and foreign macroeconomic shocks. We frame our empirical analysis in a standard new open economy macro model in...

Neben Frühindikatoren und Übertragungsmechanismen werden Lösungsansätze diskutiert. Bei den multilateralen Ansätzen führt die Einführung von Referenzzonen nicht weiter, die Behinderung des internationalen Kapitalverkehrs ist mit erheblichen Wohlfahrtsverlusten verbunden. Der...
