Mardi | 2011-12-13 B103 Mazen KEBEWAR L’objectif de cet article est d’analyser l’impact de la structure du capital sur la profitabilité. Cet impact peut être expliqué par trois théories essentielles: la théorie du signal, l’influence de la fiscalité et la théorie de l’agence. Nous montrons, à partir d’un échantillon de 9136 entreprises réparties sur sept secteurs prises sur la période 1999-2006, à l’aide d’une étude sur panel dynamique en utilisant la méthode des moments généralisée (GMM), qu’il y a une […]

Mardi | 2011-12-06 B103 Comlanvi Jude EGGOH – Muhammad KHAN Using a large panel data of both developed and developing economies and based on the PSTR and dynamic GMM techniques, this paper highlights two aspects of the inflation-growth relationship. First, it analyzes non-linearity and offersseveral thresholds for the global sample as well as for different income specific sub-samples. Second, it identifies some indirect channels effectualfor inflation-growth non-linearity. Our empirical results substantiate both views and validate the fact that inflation-growth non-linearity […]

Mercredi | 2011-11-23 B103 Syed Muhammad Noaman Ahmed SHAH According to theoretical models of valuing risky corporate securities, risk of default is primary component in the overall yield spread. However, sizable empirical literature considers it otherwise by giving more importance to non-default risk factors. Current study empirically attempts to provide answer to this question by presuming that problem lies in the empirical measurement technique. By using post-hoc estimator approach of Lubotsky & Wittenberg 2006, we construct an efficient indicator for […]

Mardi | 2011-11-08 B103 Florent BRESSON – Jean-Yves DUCLOS The paper deals with poverty orderings when the value of multidimensional attributes can be compared on a same scale, such as with income of different types or from different members of the same household. The dominance criteria extend the power of earlier multidimensional dominance tests (see Duclos et al. 2006) by making (reasonable) assumptions on the relative marginal contributions of each dimensional attribute to poverty. The paper focuses on an important […]

Mardi | 2011-10-25 B103 Thierry BAUDASSE – Rémi BAZILLIER – Cristina BOBOC-TRANDAS This paper aims at providing empirical evidences concerning the linkages betweengender equality and emigration. To analyze such linkages, two theoreticalhypothesis can be made. The rst one is that gender discrimination in origincountries can be a push factor for women. Therefore an improvement of genderequality would decrease the flow of female migrants. The second one is that gender discrimination may create a gender bias » in the selection of migrants […]

Mardi | 2011-10-19 C003 Manuel RUIZ-MARIN We propose the first statistical test to determine, given a spatial process, if the spatial structure is generated by a deterministic, rather than by a stochastic, process. The conditions under which the test can be applied are really weak. The advantages of the presented methods are simplicity, invariance respect to monotonic transformations and the applicability of the test regardless the discrete or continuous nature of the data generating process. We conduct several simulation studies […]

Mercredi | 2011-10-12 William TELKES Nowadays, many biotechnology companies are the source of scientific and technological breakthroughs and this is especially true in the pharmaceutical industry. However, developing such innovations is particularly risky. As these innovative ventures evolve in a context of high uncertainty and as their financial needs are quite large, especially when it comes to fund clinical tests, many of them have great difficulties in finding potential funding sources. Many traditional funding sources, such as banks, are unwilling […]

Mardi | 2011-09-27 B103 Jorge E. RESTREPO – Scott ROGER – Carlos J. GARCIA A DSGE model is used to examine whether including the exchange rate in the central bank’s policy rule can improve economic performance. Smoothing the exchange rate helps both financially robust economies and financially-vulnerable emerging economies in handling risk premium shocks and, given a small weight placed on the exchange rate, the effects on inflation and output volatility are minimal with demand and cost-push shocks. Financially vulnerable […]
