We analyse the effectiveness of optimal simple and implementable monetary and fiscal policy rules in stabilising economic activity, inflation and government debt in face of an occasionally binding lower bound on the nominal interest rate in a New Keynesian model. We show that, within the...

We investigate open economy dimensions of optimal monetary and fiscal policy at the zero lower bound (ZLB) in a small open economy model. At positive interest rates, the trade elasticity has negligible effects on optimal policy. In contrast, at the ZLB, the trade elasticity plays a key role in...

It is well known that the long-run viability of a fixed exchange rate regime imposes constraints on monetary policy. This paper shows that, in a model with forward-looking agents, short-run viability imposes a fiscal constraint. When policy change, which destroys long-run viability, also...

It is conventionally held that countries are worse off by forming a monetary union when it comes to macroeconomic stabilization. However, this conventional view relies on assuming that monetary policy is conducted optimally. Relaxing the assumption of optimal monetary policy not only uncovers...

Differential requirements for seigniorage provide a weak case for retaining monetary independence. As regards adjustment to asymmetric shocks, nominal exchange rate flexibility is at best a limited blessing and at worst a limited curse. Absence of significant fiscal redistribution mechanisms...

According to Frankel and Catao (2011), a commodity exporting developing economy is advised to target the output price index rather than consumer price index, as the former monetary policy is automatically countercyclical against the volatile terms of trade shock. This paper constructs a dynamic...

Halving the US current account deficit as a share of GDP is likely to impose a burden of $2,350 per capita on the United States, which explains why US policymakers want to postpone adjustment. The rest of the world relies on the economic stimulus of a widening US external deficit, which explains...
