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...

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...

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,...

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...

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...

Ratios that indicate the statistical significance of a fund’s alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance...

The GM and Ford downgrade to junk status during May 2005 caused a wide-spread sell-off in their corporate bonds. Using a novel dataset, we document that this sell-off appears to have generated significant liquidity risk for market-makers, as evidenced in the significant imbalance in their quotes...

Political economists interested in discerning the effects of election outcomes on the economy have been hampered by the problem that economic outcomes also influence elections. We sidestep these problems by analyzing movements in economic indicators caused by clearly exogenous changes in...

The aim of this paper is to compare various methods which extract a Risk Neutral Density (RND) out of PIBOR, as well as of Notional interest rate futures options, and to investigate how traders react to a political event. We first focus on five dates surrounding the 1997 snap election and...
