    Let (X,CalX,mu)(X, Cal X, mu) be a measure space, and let CalM(X,CalX,mu)Cal M(X,Cal X,mu) denote the set of the mumu-almost surely strictly positive probability densities. It was shown by G. Pistone and C. Sempi (1995) that the global geometry on CalM(X,CalX,mu)Cal M(X,Cal X,mu) can be realized by an affine atlas whose charts are defined locally by the mappings CalM(X,CalX,mu)supsetCalUpiqmapstolog(q/p)+K(p,q)inBpCal M(X,Cal X,mu)supset Cal U_p i q mapsto log(q/p) + K(p,q)in B_p, where CalUpCal U_p is a suitable open set containing pp, K(p,q)K(p,q) is the Kullback-Leibler relative information and BpB_p is the vector space of centered and exponentially (pcdotmu)(pcdotmu)-integrable random variables. In the present paper we study the transformation of such an atlas and the related manifold structure under basic transformations, that is measurable transformation of the sample space. A generalization of the mixed parameterization method for exponential models is also presented

    Chapter of a multidisciplinary international book co-edited by the author in the framework of a large excellence 5ys. project funded by the Austrian Research Fund (Forschungswissenschaftsfonds) on international tax coordination. The author pleads for a combined legal and economic methodology to alter the existing allocation rules in tax treaties with developing countries in order to preserve the international tax policy decisions of the developing countries and enhance international tax justice. The content analyses the criticism to tax sparing clauses, pleading for its reconsideration, and supports a more frequent use of exclusive allocation of taxing powers. The chapter critically reviews the reasons for the current structure tax treaty clauses and proposes for alternative solutions, which the author has also tested when drafting the Model Latin American Tax Convention with an international research group on behalf of the Instituto Latinoamericano de Derecho Tributario (ILADT). The chapter was drafted in the framework of research activities monitoring the development of European tax law for the European Science Foundation as Awardee of the European Young Investigator Award
