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...

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...

This overview paper examines two main issues. The first is why the exchange rate matters, especially for emerging market economies. The second is under what circumstances and how countries have dealt with the challenges posed by the exchange rate in recent years in the context of inflation...

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...

In a standard New Keynesian model, a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal, timeless perspective, precommitment policy. By stabilizing output gap changes, the central bank...

The establishment of independent authorities for monetary policy and for competition policy was part of the institutional consensus of the Great Moderation. The paper contrasts how policy has operated in the two spheres, especially as regards the role of law. It then discusses the application of...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...
