Taking the mean-variance portfolio model as a benchmark, we compute the optimally diversified portfolio for banks located in France, Germany, the U.K., and the U.S. under different assumptions about currency hedging. We compare these optimal portfolios to the actual cross-border assets of banks...

The excess sensitivity of investment to cash flow has been demonstrated in numerous studies. Recent research has identified differences in the degree of sensitivity across countries, which it ascribes to the nature of the lender-borrower relationship in the financial systems of those countries....

Recent theoretical research has studied extensively the link between wage setting and monetary policymaking in unionized economies. This paper addresses the question of the role of monetary uncertainty from both an empirical and theoretical point of view. Our analysis is based on a simple model...

This paper studies the behaviour of Internet prices. It compares price rigidities on the Internet and in traditional brick-and-mortar stores and provides a cross-country perspective. The data set covers a broad range of items typically sold over the Internet. It includes more than 5 million...

The paper presents the German block of the ESCB multi-country model. It builds on previous modelling work on the Area Wide Model and other country blocks of the ESCB multicountry-model. Whilst being analogous to these models in following a common modelling approach and the same theoretical...

An aggregation exercise is proposed that aims at in-vestigating whether the fast average adjustment of the disaggregate inflation series of the euro area CPI translates into the slow adjustment of euro area aggregate inflation. We first estimate a dynamic factor model for 404 inflation...

In this paper we compare alternative approaches for the construction of time series of macroeconomic variables for Unified Germany prior to 1991, and then use them for the construction of corresponding time series for the euro area. The resulting series for Germany and the euro area are compared...

In a famous episode of financial history which lasted over eight years, the market for the future on the Bund moved entirely from LIFFE, a London-based derivatives exchange, to DTB, a Frankfurt-based exchange. This paper studies the determinants of the observed dynamics, using a novel panel...

This paper proposes an equilibrium relationship between expected exchange rate changes and differentials in expected returns on risky assets. We show that when expected returns on a risky asset in a certain economy are higher than the returns that are expected from investing in a risky asset in...

This paper attempts to model the nominal and real exchange rate for Ireland, relative to Germany and the UK from 1975 to 2003. It offers an overview of the theory of purchasing power parity (PPP), focusing particularly on likely sources of nonlinearity. Potential difficulties in placing the...
