[more ▼] The hedge fund industry has experienced some very troublesome periods in the recent past. In this study, we test the efficiency of simple and advanced risk measures during these difficult market periods according to the Basel II requirements. We concentrate on Fund of Hedge Fund (FoHF) data, as some studies propose that they suffer least from database and measurement biases, and are therefore likely to yield the most representative results compared to other alternative investment data. We examine model stability and risk measure efficiency using unconditional and conditional GMMbased and likelihood ratio tests, as well as independence tests.We find that model stability is very dependent on the successful specification of autoregressive and volatility models. In addition, custom quantile estimation is less susceptible to misspecification than volatility models. Further, we assess the hypothesis of market efficiency for the special case of FoHF. Finally, we find evidence of different level of managerial skill in terms of asset choice, allocation and market timing.

[more ▼] Dans le cadre d’une étude intensive sur échantillon restreint, l’application du codage optimal au niveau des valeurs Delta (différences posttest/pré-test) peut permettre de dégager des dimensions latentes faisant sens du point de vue de la théorie et permettant de mieux comprendre le changement manifeste. Celui-ci est mesuré au moyen de différents types d’outils, complémentaires entre eux (échelles psychométriques, tests projectifs, épreuves expressives, schémas d’observation comportementale, critères de validation externe). Nous illustrons l’intérêt de cette stratégie au moyen d’un exemple d’application, tiré d’une étude d’évaluation d’ateliers de musicothérapie offerts à des élèves surdoués en situation d’échec scolaire (n = 20). Nous présentons les changements pré-test/post-test (test signe-rang de Wilcoxon) au niveau des outils suivants : le d2 (Brickenkamp, 1994 [39]), le TSD-Z (Urban et Jellen, 1995 [40]) et le thematic apperception test (TAT) (Murray, 1991 [41]), ainsi que les résultats de l’étude corrélationnelle (Rho de Spearman) et multidimensionnelle (PRINCALS appliquée sur valeurs Delta). Des changements significatifs sont apparus au niveau de la capacité de concentration, de l’élaboration imaginaire et symbolique de l’agressivité, ainsi qu’au niveau de la créativité picturale et littéraire. Les dimensions latentes dégagées à partir du codage optimal font sens du point de vue de la théorie. Nous proposons une modélisation théorique du mode d’action de la musicothérapie dans la levée du blocage, distinguant, d’un côté, les effets stimulants ou équilibrants à court terme, d’un autre côté les effets restructurants à long terme. Au sein d’une démarche exploratoire, la stratégie adoptée peut ouvrir des pistes pour la recherche future. [less ▲] Detailed reference viewed: 199 (4 UL) Arts Therapies and Society.
