With heterogeneous productivity and sticky prices in the short run, exchange rate changes can generate real effects on agents in the economy; the result is that the currency regime becomes a policy variable amenable to political competition. This paper discusses how special interests and...

We estimate the causal impact of countercyclical interest rates on macroeconomic outcomes in open economies. To identify countercyclical interest rates, we construct a new database of short-term interest rates, principal exports, and international commodity prices for 40 economies from 1870 to...

We introduce "financial imperfections" -- asymmetric net wealth positions, incomplete risk-sharing, and interest rate spreads across member countries -- in a prototypical two-country currency union model and study implications for monetary policy transmission mechanism and optimal policy. In...

The uncovered interest rate parity condition lies at the heart of the "impossible trinity", stating that the three objectives of fixed exchange rates, free capital flows, and independent monetary policy cannot be pursued simultaneously. We argue that although monetary unification does indeed...

On 10 January 2013 the ECB Governing Council decided “to keep the key ECB interest rates unchanged” based on an assessment of a ‚contained‘ inflationary pressure and a weak economic activity, a contraction of real GDP in second and third quarter of 2012. Similar decisions have been taken...

Interest rates have moved closely together internationally in recent years, despite business cycles often being at different stages across countries. We investigate whether international monetary spillovers drove this co-movement, ie whether interest rates in core advanced economies drove...

When does the combination of flexible exchange rates and domestic inflation-oriented monetary policy guarantee insulation from global financial conditions? We examine a dynamic global game model of international portfolio flows where, for some combination of parameters, the unique equilibrium...
