Analysis of the design of institutions to counteract failures of monetary commitment has largely proceeded in a vacuum. It has ignored similar commitment problems in fiscal policy and in structural adjustment; and it has ignored coordination problems between monetary and fiscal policy. Optimal...

We provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such...

This 2003 Institute for Fiscal Studies Lecture addresses two sets of issues relevant to current and prospective future E(M)U members: the consequences of the Stability and Growth Pact for fiscal-financial sustainability and macroeconomic stability, and some risks associated with operational...

We log-linearise the Dellas and Tavlas (DT) model of monetary union and solve it analytically. We find that the intuition of optimal currency analysis of DT's second generation open economy model is essentially the same as that of first generation models. Monetary union results in no welfare...

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

Sovereign risk premia in several euro area countries have risen markedly since 2008, driving up credit spreads in the private sector as well. We propose a New Keynesian model of a two-region monetary union that accounts for this "sovereign risk channel." The model is calibrated to the euro area...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

In contrast to the notion that the exchange-rate regime is non-neutral, there is little evidence that EMU has systematically changed the European business cycle. In fact, we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the euro. Exceptions...

The interwar period was marked by the end of the classical gold standard regime and new levels of macroeconomic disorder in the world economy. The interwar disorder is often linked to policies inconsistent with the constraint of the open-economy trilemma - the inability of policy-makers...

The U.S. dollar holds a dominant place in the invoicing of international trade, along two complementary dimensions. First, most U.S. exports and imports invoiced in dollars. Second, trade flows that do not involve the United States are also substantially invoiced in dollars, an aspect that has...
