Débat du pouvoir et des finalités des marchés financiers et plaide pour une réhabilitation de la politique qui peut constituer un contrepoids.

L'auteur tente de montrer que les menaces réelles liées à la mondialisation peuvent être évitées si la politique économique reconnaît dans le social une composante essentielle de l'efficacité économique.

Pour faire en sorte que le progrès social ne reste pas en panne, la politique doit imposer sa loi aux marchés financiers même si ceux-ci sont indispensables au fonctionnement de l'économie française en aidant à répartir la masse des risques. L'échec de la gauche en France s'explique...

We propose a new method to model hedge fund risk exposures using relatively high frequency conditioning variables. In a large sample of funds, we find substantial evidence that hedge fund risk exposures vary across and within months, and that capturing within-month variation is more important...

This paper presents new stylized facts on the distribution of the home bias at the fund level. We find (i) a large heterogeneity in the degree of home bias across mutual funds; (ii) a positive correlation between the size of funds and home bias; and (iii) a positive correlation between the size...

We propose a new method to capture changes in hedge funds' exposures to risk factors, exploiting information from relatively high frequency conditioning variables. Using a consolidated database of nearly 15,000 individual hedge funds between 1994 and 2009, we find substantial evidence that hedge...

This paper examines the quality of credit ratings assigned to banks in Europe and the United States by the three largest rating agencies over the past two decades. We interpret credit ratings as relative assessments of creditworthiness, and define a new ordinal metric of rating error based on...

The eurozone has a single short-term nominal interest rate, but monetary policy conditions measured by either real short-term interest rates or Taylor rule residuals varied substantially across countries in the period from 2003-2010. We use this cross-country variation in the (local) tightness...

This paper provides empirical evidence of the impact of hedge funds on asset markets. We construct a simple measure of the aggregate illiquidity of hedge fund portfolios, and show that it has strong in- and out-of-sample forecasting power for 72 portfolios of international equities, corporate...

We analyze the reliability of voluntary disclosures of financial information, focusing on widely-employed publicly available hedge fund databases. Tracking changes to statements of historical performance recorded at different points in time between 2007 and 2011, we find that historical returns...
