We explore the implications of monetary unification for real interest rates and (relative) public debt levels. The adoption of a common monetary policy renders the risk-return characteristics of the participating countries more similar, so that the substitutability of their public debt increases...

The paper examines the monetary-fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. We first show that monetary uncertainty disciplines fiscal policymakers and thereby reduces taxes, average inflation and output distortions. However, as more...

Following the experience of the global financial crisis, central banks have been asked to undertake unprecedented responsibilities. Governments and the public appear to have high expectations that monetary policy can provide solutions to problems that do not necessarily fit in the realm of...

This paper reviews whether and how the ongoing financial crisis has influenced central banking policy practice. Taking a historical perspective, it argues that throughout the existence of central banks the main objective has remained the same¯stability. What has been evolving over time, and has...

The paper models the interaction between risk taking in the financial sector and central bank policy for the case of pure illiquidity risk. It is shown that, when bad states are highly unlikely, public provision of liquidity may improve the allocation, even though it encourages more risk taking...

This paper reviews the challenges faced by central banks in recent years in order to evaluate their policy implications going forward. To highlight the genuine uncertainty surrounding the lessons to be drawn, the paper examines recent experience through two intentionally polarised perspectives,...

In the economic environment that has been emerging over the last couple of decades, it is more likely that the occasional build-up of financial imbalances, typically in the form of unsustainable credit and asset price booms, will occur against the background of low and stable inflation, posing a...

What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national rates of inflation and growth? We find that a central bank that...

What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national welfare losses based on national rates of inflation and growth?...

The paper models the links between financial fragility, asset markets and monetary policy. It is shown that central banks concern about the cost of financial disruption generates an asymmetric response, thus contributing to the creation of an asset price bubble. In an economy with a highly...
