We propose two new criteria to evaluate the appropriateness of a country joining a larger currency area. The first, asymmetric-shocks-on-its-head, argues that asymmetric shocks to real GDP provide an argument for adopting a common currency. The argument comes in three steps. First, independent...

We analyse deflationary bubbles in a model where money is the only financial asset. We show that such bubbles are consistent with the households transversality condition if and only if the nominal money stock is falling. Our results are in sharp contrast to those in several prominent...

In a dynamic optimising model with costly tax collection, a tax cut by one nation creates positive externalities for the rest of the world if initial public debt stocks are positive. By reducing tax collection costs, current tax cuts boost the resources available for current private consumption,...

If Stage Three of EMU starts on January 1, 1999, transition issues remain on two time scales. Until July 1, 2002, national currencies and the euro co-exist as legal tender. We argue that intra-EMU currency risk exists in principle during that period, but that no EMU member can be forced out...

The purpose of the UDROP proposal is to prevent debt rollover crises for foreign-currency-enominated debt instruments. For such liabilities, there is no international analogue to the domestic lender of last resort or to domestic deposit insurance. UDROP stands for Universal Debt Rollover Option...

Large and growing levels of public debt in the United States, United Kingdom, Japan and the Euro Area raise new interest in the cross-country effects of a large open economy’s deficits. We consider a dynamic optimising model with costly tax collection and exogenously given public spending and...

In an attempt to clean up an unruly literature, we specify the necessary and sufficient conditions for household optimality in a model where money is the only financial asset and provide the relevant proofs. We use our results to analyse when deflationary bubbles can and cannot exist. Our...
