This article deals with the Value at Risk concept as it is used in practice. We show that, like the Gaussian distribution, elliptical distributions lend themselves to simple practical computations. All necessary computations are detailed for the symmetric hyperbolic distributions. A test on real stock market and exchange rate data shows the new distributions fit the data better and outperform e...

Özetçe. Günümüz şirketleri, müşterilerinin beklentilerini anlamak ve bu beklentilere hızlı ve doğru bir şekilde tepki vermek durumundadır.

We draw a distinction between the concepts of purchase affordability (whether a household is able to borrow enough funds to purchase a house) and repayment affordability (the burden imposed on a household of repaying the mortgage). We operationalize this distinction in the context of a new methodology for constructing affordability measures that draws on the value-at-risk concept and takes acco...

We adopt a theory of relativisation based on the idea that relatives, like wh-constructions in the analysis of Chomsky (1998), require two sorts of features to construct their LF-interpretation. We argue that it is the variable interpetability of these features that gives rise to different syntactic patterns. We use this theory to provide an explanation for some curious syntactic facts found in...
