This paper investigates the position of the Phillips curve in a single currency area, when the countries have different levels of unemployment. We will use the aggregation hypothesis to show that allowing for the dispersion of unemployment is essential to quantifying the level of inflation...

Surowiecki (2004) argues that collective predictions are better than individual predictions and calls that the Wisdom of the Crowds. We use an analytical information model to demonstrate and explain this. Then we see how these two predictions are affected by better public information and show...

In their seminal paper, Morris and Shin (2002a) argued that increasing the precision of public information is not always bene.cial to social welfare. Svensson (2005) however has disputed this by saying that although feasible, the conditions for which this was true, were not at all that likely....

Recent literature on monetary policy has emphasised the role of expectations and the merits of tying them down through credible commitment. However, although always in favour of reaping the benefits of having committed, Central Banks worry about the fact that in real time, it is not always easy...

In situations of relative calm and certainty, policy makers have confidence in the mechanisms at work and feel capable of attaining precise and ambitious results. As the environment becomes less and less certain, policy makers are confronted with the fact that there is a trade-off between the...

We provide a framework for analysing the choice between optimal and robust rules in the presence of paradigm uncertainty in monetary policy. We thus provide for two issues: …rst, we discuss the conditions of uncertainty that render a robust rule a preferable substitute to optimal rules and...

The benefits of inflation targeting by comparison to alternative regimesare understood to be in terms of providing clearer objectives that help pin down private sector expectations in the long run. We argue that the mechanism for achieving this rests on the fact that monetary policy can be...
