Some central banks have a reputation for being secretive. A justification for this behaviour that we find in the literature is that being transparent about operations and beliefs hinders the central bank in achieving the best outcome. In other words, a central bank needs flexibility and...

We study the problem of a central bank whose policy actions simultaneously affect the information flow about its expectations-augmented Phillips curve and its reputation for toughness in fighting inflation. In an environment with an unknown relationship between inflation surprises and output,...

In this Paper, we suggest a new motivation for why central banks appear averse to reversing recent changes in their interest rate. We show, in a standard monetary model with forward-looking expectations, data uncertainty and parameter uncertainty, that there is a learning cost associated with...

The European Economic and Monetary Union (EMU) has created a new economic area, larger and closer with respect to the rest of the world. Area-specific shocks are thus more important in EMU than country-specific shocks used to be in the previous states, e.g. in Germany. It is thus not surprising...

The first part of the paper analyzes the inflationary risks associated with price liberalization, the welfare costs of inflation and the difficulties of East European central banks in pursuing non-inflationary policies. The main obstacles are the low credibility of stabilization policies and a...

A central tenet of inflation targeting is that establishing and maintaining well-anchored inflation expectations are essential. In this paper, we reexamine the role of key elements of the inflation targeting framework towards this end, in the context of an economy where economic agents have an...

Why were people so unprepared for the global financial crisis, the European debt crisis, and the Fukushima nuclear accident? To address this question, we study a model in which agents make state-contingent plans - think about actions in different contingencies - subject to the constraint that...

Any security’s expected return can be decomposed into its “carry” and its expected price appreciation, where carry is a model-free characteristic that can be observed in advance. While carry has been studied almost exclusively for currencies, we find that carry predicts returns both in the...

We model the demand-pressure effect on prices when options cannot be perfectly hedged. The model shows that demand pressure in one option contract increases its price by an amount proportional to the variance of the unhedgeable part of the option. Similarly, the demand pressure increases the...

Insider trading in the credit derivatives market has become a significant concern for regulators and participants. This paper attempts to quantify the problem. Using news reflected in the stock market as a benchmark for public information, we report evidence of significant incremental...
