Central banks invest their foreign exchange reserves predominantly in government securities. By means of a panel data analysis we examine the relationship between reserve currency status and public budget balance during different constellations of the international monetary system: the sterling...

The New Keynesian DSGE literature has come to the consensus that, from the perspective of business cycle stabilization, countries are worse off in terms of welfare by forming a monetary union. This consensus, however, is based on the assumption of monetary policy being optimal. Using a standard...

In 1976 Vaubel suggested using the variation of real exchange rates when evaluating the desirability of a monetary union within a group of currencies (Vaubel 1976). Currency uni cation is less desirable, the more often real exchange rate adjustments are needed. Ten years later, Mussa...

The desirability of flexible exchange rates is a central tenet in international macroeconomics. We show that, with forward-looking staggered pricing, this result crucially depends on the monetary authority's ability to commit. Under full commitment, flexible exchange rates generally dominate a...

The study presents an empirical strategy for determining global currency bloc equilibria. The procedure includes, first, a nested logit estimation of the combined determinants of currency regime and anchor currency choice; second, a test for a welfare-maximising regime decision, in which estimates...

Early warning systems (EWSs) are subject to restrictions that apply to exchange rates in general: fundamentals matter but their influence is small and unstable. Keeping this in mind, five lessons emerge : First, EWSs have robust forecasting power and thus help policy-makers to prevent crises....

Evidence on the effectiveness of FX interventions in the prevailing higher frequency approaches leaves a gap at horizons going beyond a few days. This is addressed by identifying a structural vector autoregressive model for the daily frequency with an external instrument. Using Japanese data, we...

This paper provides a modelling framework for evaluating the exchange rate dynamics in target zone regime with undisclosed bands. We generalize the literature to allow for asymmetric one-sided regimes. Market participants' expectation formation about the undisclosed band change as they learn...

This paper re-examines the role of real supply shocks in international business cycles. In contrast to previous studies, we extend the concept of supply shocks beyond the productivity shock towards labor supply shocks. Our analysis simultaneously identifies five real and nominal disturbances in...

This paper provides an explanation for the observed decline of exchange rate pass-through into import prices by modeling the effects of financial market integration on the optimal choice of the pricing currency in the context of rigid nominal goods prices. Contrary to previous literature, the...
