We formulate well-known discretionary accruals models in an investment setting. Given that accruals basically consist of short-term investment, we introduce, (i) cash-flows, as a proxy for financial constraints and other financial markets imperfections, and (ii) Tobin’s q as a measure of...

The noninterest income banks generate from their off-balance-sheet activities contributes greatly to the volatility of their operating revenues. Using Canadian data, we apply a modified Hausman procedure based on higher moments instruments and revisit this phenomenon to establish that the share...

This paper combines the idea of preliminary test and ridge regression methodology, when it is suspected that the regression coefficients may be restricted to a subspace. The preliminary test ridge regression estimators (PTRRE) based on the Wald (W), Likelihood Ratio (LR) and Lagrangian...

We prove a functional limit theorem for the rescaled occupation time fluctuations of a (d, , )- branching particle system (particles moving in Rd according to a symmetric -stable L´evy process, branching law in the domain of attraction of a (1 + )-stable law, 0 < < 1, uniform Poisson initial state) in the case of intermediate dimensions, / < d < (1 + )/. The limit is a process of the form K, where K is a constant, is the Lebesgue measure on Rd, and = (t)t0 is a (1+)-stable process which has long range dependence. There are two long range dependence regimes, one for all > d/(d + ), which coincides with...</<>

Markets makers quote many option categories in terms of implicit volatility. In doing so, they can reactivate the Black and Scholes model which assumes that the volatility of an option underlying is constant while it is highly variable. First of all, this article, whose purpose is very...

Cette étude présente une comparaison de deux méthodologies multicritère d’aide à la décision, l’analyse hiérarchique de Saaty (AHP, Analytic Hierarchy Process) et les ensembles approximatifs (DRSA, Dominance- based rough set approach). Cette recherche a été appliquée dans le cas...
