Money managers are rewarded for increasing the value of assets under management, and predominantly so in the mutual fund industry. This gives the manager an implicit incentive to exploit the well-documented positive fund-flows to relative-performance relationship by manipulating her risk...

This paper examines hierarchies’ role in the organization of human-capital-intensive production. We develop an equilibrium model of hierarchical organization, then provide empirical evidence using confidential data on thousands of law offices from the 1992 Census of Services. We show how the...

Les prestations de services professionnels sont par définition intangibles et génèrent en conséquence une perception de risque et d’incertitude chez le client. Pour y remédier, la confiance a été identifiée comme étant la solution idéale. Or, l’idée dominante est que le...

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...

In this note it is argued that the estimation error in Value-at-Risk predictors gives rise to underestimation of portfolio risk. We propose a simple correction and find in an empirical illustration that it is economically relevant.

In general, the properties of the conditional distribution of multiple period returns do not follow easily from the one-period data generating process. This renders computation of Value-at-Risk and Expected Shortfall for multiple period returns a non-trivial task. In this paper we consider some...

In the estimation of risk measures such as Value at Risk and Expected shortfall relatively short estimation windows are typically used rendering the estimation error a possibly non-negligible component. In this paper we build upon previous results for the Value at Risk and discuss how the...

Dans cet article, l’analyse des réseaux sociaux (ARS) est décrite comme une nouvelle méthodologie d’étude des communautés en ligne. Afin d’amener à une meilleure compréhension de l’ARS, une synthèse des recherches antérieures est proposée. Elle détaille les techniques de...

Principalement sous forme de bannières, la communication sur Internet offre des possibilités de communication attractives mais ne représente encore qu’une très faible partie des investissements publicitaires tous média considérés. La mesure de l’audience et sa qualification sont...
