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 […]

Mardi | 2011-06-07 B103 – 16h20 Hippolyte D’ALBIS In this article, we challenge the common thought that the annuity contract proposed by Yaari in his seminal 1965’s paper is optimal. We indeed show, in a standard neo-classical framework, that another contract, which actually resembles much more to the contracts that are proposed in the  » real world » , may be preferred by rational individuals. According to this contract, the annuities are an illiquid asset and the premium is age independent. […]

Mardi | 2011-05-24 B211 Kristian BEHRENS – Giordano MION – Yasusada MURATA – Jens SÜDEKUM The spatial structure of an economy is determined by the trade-off between agglomerationand dispersion forces. This trade-off crucially depends on spatial frictions – trade frictions for shipping goods across cities and urban frictions for concentrating people and firms in cities. Little is known to date about the quantitative importance of those frictions. To fill this gap, we develop a model that allows for the joint […]
