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...

In the context of Markstrat simulation game, a group learning scale has been developed based on Churchill’s work (1979). Our methodology reveals that it is possible to measure group learning by developing a specific scale. This scale appears as reliable and valid. The scale falls into two...

The “We concept” is proposed as a psychographic segmentation variable for products requiring a family-based purchase decision . This research describes the relation of expression of the “We concept” facets with the preferred car image. A scale of the preferred car image (pleasure,...
