Financial contagion and systemic risk measures are commonly derived from conditional quantiles by using imposed model assumptions such as a linear parametrization. In this paper, we provide model free measures for contagion and systemic risk which are independent of the specifcation of...

Ordinary least squares regression residuals have a distribution that is dependent on a scale parameter. The term 'Studentization' is commonly used to describe a scale parameter dependent quantity U by a scale estimate S such that the resulting ratio, U/S, has a distribution that is free of from...

The Azzalini skew-t distributions are popular because of their theoretical foundation and the availability of computational methods in the R package sn. One difficulty with this skew-t family is that the elements of the expected information matrix do not have closed form analytic formulas. Thus,...

The article examines the process of formation inventory of the enterprise and determines the optimal volume of commodity resources for sale. A generalization of author’s approaches to the formation and evaluation of inventories of the enterprise is carried out. The marketing-logistic approach...

Investors take for granted that returns are recorded in units of time, such as days, months, or years. Yet some time periods include unusual events that reasonably cause asset prices to change, whereas other periods are relatively free of unusual events, in which case returns mostly reflect...

Among the sources to get statistical data, along with other procedures such as census surveys, statistical reports, investigations, or monographies, statistical soundings are a way that is fully developing at present. Due to its efficiency in getting data at low costs, the sounding method is...

This work aims to understand the poverty phenomenon in Morocco. It is based on the multidimensional poverty assessment and analysis, through the Alkire and Foster approach to poverty measurement (2007). It is also based on the indicators which will allow us to measure the incidence of poverty by...

Infolge der Regionalisierung von Wirtschafts- und Strukturpolitik entstehen entweder vollkommen neue Institutionen (horizontale Regionalisierung) oder Institutionen mit neuen Kompetenzen (vertikale Regionalisierung). Der Erfolg einer Regionalisierungspolitik läßt sich am Grad der...
