The uniqueness of bounded local equilibria under interest rate rules is analyzed in a model with sticky information à la Mankiw and Reis (2002). The main results are tighter bounds on monetary policy than in sticky-price models, irrelevance ofthe degree of output-gap targeting for determinacy,...

We use a two-country model with a central bank maximizing union-wide welfareand two fiscal authorities minimizing comparable, but slightly differentcountry-wide losses. We analyze the rivalry between the three authorities inseven static games. Comparing a homogeneous with a heterogeneous...

This paper explains a currency crisis as an outcome of a switch in how monetarypolicy and fiscal policy are coordinated. The paper develops a model of an open economy in which monetary policy starts active, fiscal policy starts passive and, in a particular state of nature, monetary policy...

Time consistency problems can arise when environmental taxes are employedto encourage firms to take irreversible abatement decisions. Setting a high carbontax, for instance, would induce firms to invest in low-carbon technology,yet once investment has occurred the government can then reduce the...

New Keynesian models of monetary policy predict no role for monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. This paper evaluates the empirical validity of this prediction by studying the effects...

A central proposition in research on the role that banks play in the transmission mechanism is that monetary policy imparts a direct impact on deposits and that deposits, insofar as they constitute the supply of loanable funds, act as the driving force of bank lending. This paper argues that the...

This paper studies the optimal design of monetary policy in an optimizing two-country sticky price model. We suppose that the production sequence of final consumption goods stretches across both contries and is associated with vertical trade. Prices of final consumption goods are sticky in the...

The recent global financial crisis has led central banks to rely heavily on "unconventional" monetary policies. This alternative approach to policy has generated much discussion and a heated and at times confusing debate. The debate has been complicated by the use of different definitions and...

We study the effects of model uncertainty in a simple New Keynesian model using robustcontrol techniques. Due to the simple model structure, we are able to find closed-formsolutions for the robust control problem, analyzing both instrument rules and targetingrules under different timing...

Empirical evidence on whether the euro area monetary transmission process has changed is, at best, mixed. We argue that this inconclusiveness is likely to be due to the fact that existing empirical studies concentrate on the effects of a particular development on a specific transmission channel....
