Mardi | 2012-06-05 B103 Fayçal AMRANI Cet article propose une nouvelle explication de la faible présence des contrats mudharaba dans les bilans des banques islamiques. Nous démontrons que la quasi disparition des contrats de partage dans la pratique des institutions financières islamiques n’est pas liée à la nature de ces contrats mais à la méthode de calcul de la marge bénéficiaire des contrats mark-up. Nous proposons une méthode de calcul qui unifie le coût du financement des deux grandes catégories […]

Mercredi | 2012-05-23 B103 Abdelkader BOUDRIGA – Wafa GHARDALLOU- BEN AHMED This paper examines whether the effects of democracy on financial development are influenced by the quality of institutions using a panel dataset of a large sample of developed and developing countries over the period 1984-2006. The results indicate that democracy plays a direct important role in stimulating the financial development. Particularly, effects of democracy on financial development are enhanced by higher levels of economic institutions. Otherwise, development may be […]

Mercredi | 2012-05-16 B103 Denisa BANULESCU-RADU – Bertrand Candelon – Christophe HURLIN Considering mixed data sampling (MIDAS) regressions, we analyze the inuenceof the sampling frequency of intra-daily predictors on the accuracy of the volatility forecasts. We propose various in-sample and out-of-sample comparisons of daily,weekly and bi-weekly volatility forecasts issued from MIDAS regressions based on intra-daily regressors sampled at di erent frequencies. First, we show that increasing the frequency of the regressors improves the forecasting abilities of the MIDAS model. In […]

Mardi | 2012-04-17 B103 Aymen BELGACEM – Amine LAHIANI This paper investigates the impact of US scheduled macroeconomic announcementson the domestic, the French and the German market, respectively using anaugmented version of the multivariate DCC-GARCH model. Our setting allows toseparate the direct effect (common response), from the indirect effect(volatility transmission) of the US macroeconomic announcements on the two European markets. Empirical results show evidence of a direct reaction of French and German investors to some common as well as specific […]

Mercredi | 2012-04-11 B103 Madeleine TOMO-NKONO In light of increasing interest in the relationship between economic growth and poverty, the present paper uses panel data of CEMAC and WAEMU countries, which use commonly the CFA franc, to determine empirically the impact of growth on poverty for the period 1981–2005. During this period, CEMAC and WAEMU economic progress improved and performance in terms of poverty reduction is slightly satisfactory. Based on random-effects model, we provide estimates for poverty measures at the […]

Mardi | 2012-04-10 B103 Mathieu LEFEBVRE – Pierre PESTIEAU – Gregory PONTHIERE Under income-differentiated mortality, poverty measures reflect not only the  » true » poverty, but, also, the interferences or noise caused by the survival process at work. Such interferences lead to the Mortality Paradox: the worse the survival conditions of the poor are, the lower the measured poverty is. We examine several solutions to avoid that paradox. We identify conditions under which the extension, by means of a fictitious income, […]

Mardi | 2012-04-03 B103 Christophe BOUCHER – Jon DANIELSSON – Bertrand MAILLET – Patrick S. KOUONTCHOU The recent experience from the global financial crisis has raised serious doubts about the accuracy of standard risk measures as a tool to quantify extreme downward risks. Risk measures are hence subject to a “model risk” due, e.g., to the specification and estimation uncertainty. Therefore, regulators have proposed that financial institutions assess the “model risk” but, as yet, there is no accepted approach for […]
