The article first gives an overview of the formation and the evolution of the principle of non-refoulement under international law. The different meanings of the concept in the asylum and human rights contexts are then discussed and compared, with due regard to the convergences that arose in the course of legal developments. In doing so, this short piece also draws attention to certain controversial issues and blurred lines, which have surfaced through the practical application of the prohibition of refoulement. Identifying the contours of the concept and clarifying its content and its effects may help in appreciating the implications that stem, in the current extraordinary times of migratory movements, from the fundamental humanitarian legal principles of which the imperative of non-refoulement forms part.

A dolgozatban a legegyszerűbb kérdést feszegetjük: Hogyan kell az árakat meghatározni véletlen jövőbeli kifizetések esetén. A tárgyalás némiképpen absztrakt, de a funkcionálanalízis néhány közismert tételén kívül semmilyen más mélyebb matematikai területre nem kell hivatkozni. A dolgozat kérdése, hogy miként indokolható a várható jelenérték szabálya, vagyis hogy minden jövőbeli kifizetés jelen időpontban érvényes ára a jövőbeli kifizetés diszkontált várható értéke. A dologban az egyetlen csavar az, hogy a várható értékhez tartozó valószínűségi mértékről nem tudunk semmit. Csak annyit tudunk, hogy létezik a matematikai pénzügyek legtöbbet hivatkozott fogalma, a misztikus Q mérték. A dolgozat megírásának legfontosabb indoka az volt, hogy megpróbáltam kiiktatni a megengedett portfólió fogalmát a származtatott termékek árazásának elméletéből. Miként közismert, a származtatott termékek árazásának elmélete a fedezés fogalmára épül. (...) ____ In the article the author discusses some problems of the existence of the martingale measure. In continuous time models one should restrict the set of self financing portfolios and introduce the concept of the admissible portfolios. But to define the admissible portfolios one should either define them under the martingale measure or to turn the set of admissible portfolios to a cone which makes the interpretation of the pricing formula difficult.

In finance risk capital allocation raises important questions both from theoretical and practical points of view. How to share risk of a portfolio among its subportfolios? How to reserve capital in order to hedge existing risk and how to assign this to different business units? We use an axiomatic approach to examine risk capital allocation, that is we call for fundamental properties of the methods. Our starting point is Csóka and Pintér (2011) who show by generalizing Young (1985)'s axiomatization of the Shapley value that the requirements of Core Compatibility, Equal Treatment Property and Strong Monotonicity are irreconcilable given that risk is quantified by a coherent measure of risk. In this paper we look at these requirements using analytic and simulations tools. We examine allocation methods used in practice and also ones which are theoretically interesting. Our main result is that the problem raised by Csóka and Pintér (2011) is indeed relevant in practical applications, that is it is not only a theoretical problem. We also believe that through the characterizations of the examined methods our paper can serve as a useful guide for practitioners.
