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...

The purpose of this article is to present a multi-items scale on Web retail service quality. After reviewing the literature on this subject, two studies are presented. The first study is a qualitative one with a literature review and a series of depth individuals interviews and focus groups of...

Secondhand shopping is a growing phenomenon. While secondhand shopping motivations received a lot of attention in marketing literature, consumer reluctance to shop secondhand remains under-Researched, especially in an online context. Yet, the stakes in better understanding this reluctance are...

Trust is a crucial factor in e-commerce. However, consumers are less likely to trust unknown Web sites. This study explores how less-familiar e-commerce Web sites can use branding alliances and Web site quality to increase the likelihood of initial consumer trust. We use the associative network...

Noting that the use of Internet is not only utilitarian but experiential indeed cultural, this dissertation describes in depth and explains what people lives in their online consumer experiences. This description is done through the three great social and personal changes brought by the advent...

Based on consumer behaviors in multichannel distribution literature and academic studies on the Internet, this article focuses on how the use of the web site may influence the consumer's perception of quality in-store. This research highlights the need to redefine quality parameters taking into...
