The influential work of Obstfeld and Rogoff argues that a closing-up of the US current account deficit involves a large exchange rate adjustment. However, the Obstfeld-Rogoff model works exclusively via demand-side channels and abstracts from possible supply-side changes. We extend the framework...

This paper focuses on the role of real exchange rate volatility as a driver of portfolio home bias, and in particular as an explanation for differences in home bias across financial assets. We present a Markowitz-type portfolio selection model in which real exchange rate volatility induces a...

Since the late-1990s, the global economy is characterised by historically low risk premia and an unprecedented widening of external imbalances. This paper explores to what extent these two global trends can be understood as a reaction to three structural shocks in different regions of the global...

This paper describes in detail the methodology currently used by the European Central Bank (ECB) to determine the nominal and real effective exchange rate indices of the euro. Building on the work of Buldorini et al. (2002), it shows how the ECB’s techniques for calculating effective exchange...

Identification of structural VARs using sign restrictions has become increasingly popular in the academic literature. This paper (i) argues that identification of shocks can benefit from introducing a global dimension, and (ii) shows that summarising information by the median of the available...

Voting power methodology offers insights to understand coalition building in collective decision making. Using cooperative game theory, Banzhaf (1965) developed an index to capture the numerical importance of voters in coalition building. This voting power index is still widely used today in...

This paper examines inflation dynamics in the current EU-accession countries in central and eastern Europe, focusing particularly on the determinants of 'dual inflation', that is, diverging inflation rates for tradable and non-tradable goods. The paper draws on the recently published data for...

This paper sheds new light on the external and domestic dimension of China’s exchange rate policy. It presents an open economy model to analyse both dimensions of macroeconomic adjustment in China under both flexible and fixed exchange rate regimes. The model-based results indicate that...

This paper presents a new concept – the global roles of currencies. The concept combines the domestic and international (cross-border) use of currencies and therefore captures the overall importance of different currencies in a globalised economy. The measure of a currency’s global role is...

The paper analyses whether, and to what extent, emerging market economies (EMEs) have systemic importance for global financial markets, above and beyond their influence during crises episodes. Using a novel database of exogenous economic and political shocks for 14 systematically relevant EMEs,...
