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 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 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...

By means of qualitative studies of ethnic consumers with Moroccan, Tahitian, Turkish and Congolese backgrounds, this article demonstrates that ethnic consumers in France are experiencing reculturation through consumption, using products, brands and points of sale to negotiate this re-discovery...

This article discusses a study that attempts to reach a better understanding of how the potential franchisees come to their decisions and attempts to compare this process with franchiser's perceptions. It initially focuses on the identification and on the decision-making process of French...

We examine in this paper the issue of how institutions are maintained and the role of agency in this process. We investigate more specifically the efforts of actors to maintain the institutional order through discourse. We approach this issue through an in-depth and longitudinal study of...

Purpose – The purpose of this paper is to design, develop and evaluate a reliable and valid scale for the measurement of online retail service quality, specifically in the French context. Design/methodology/approach – Study 1 derived scale items from the literature by content analysis. Study...

Based on a study conducted in the setting of French franchise networks (sample: 428 franchisees), this research establishes the existence of a channel technological control that operates through a « panoptic effect ». The results suggest that information technologies have the capacity to...
