The paper establishes that sovereigns, like banks, need a lender of last resort (LoLR). In the euro area the ECB, with its estimated €3.4 trillion non-inflationary loss absorption capacity, is the only credible sovereign LoLR. The ECB/Eurosystem has been acting as sovereign LoLR through its...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. We show that even were this the case, there remains a...

This paper studies the optimal debt repayment policy of a government facing a credibility problem: the public is uncertain about whether the outstanding public debt will be repaid in full or in part and requires a risk premium to roll it over. The model determines when it is optimal for the...

We analyze a two-country zone facing a joint inflationary shock and responding with coordinated and uncoordinated monetary and fiscal policies. We show that the standard presumption that the absence of coordination results in an excessive exchange rate appreciation of the zone with respect to...

This paper assesses how monetary authorities behave and how they interact. Pooled data for the 15 members of the European Union except Luxembourg and five other OECD countries serves to answer these questions. Three basic conclusions emerge. First, fiscal policy responds to the ratio of public...

We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead...

We derive a set of stylized facts on the effects of non-systematic fiscal policy in the four largest countries of the Euro area, and discuss their implications for the fiscal policy coordination debate, for the effectiveness of fiscal shocks in stabilizing the economies, and for the interaction...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

Banking systems have rapidly grown to a point where for many countries bank assets amount to multiples of GDP. As a consequence, government’s capacity to provide stability-enhancing fiscal guarantees against systemic crises can no longer be taken for granted. As regulation of dynamic financial...

We examine global economic dynamics under infinite-horizon learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), we find that under normal monetary and fiscal policy the intended steady state is locally but...
