Since the 1960s, Western Europe has been host to a large Turkish immigrant community. While many such communities shift to the majority language in the space of a few generations, language maintenance is remarkably successful in this community. This is partially because of continuing immigration, but it is also typical of a transnational identity that characterizes many bilingual communities in...

Modern state is conceptually and subjectively complicated as per the wide range of concepts and subjects related to it, therefore the context is provided to present the viewpoints on its identity and nature. Based on this, human sciences Scientifics investigate it from different perspectives. Complexity of the nature of modern State, arises the various theories around it, despite bring serious ...

Many multicriteria problems in economics and finance require that efficient solutions be found. A recent contribution to production theory established a characterization of efficient points under closedness and free-disposability (Bonnisseau and Crettez in Econ Theory 31(2):213–223, 2007, Theorem 1). However, as will be shown using a number of examples, these results cannot be applied to simple...

This paper is about dotted representations of efficient frontiers. Dotted representations, as in portfolio selection, can often be the most practical way of communicating an efficient frontier. The most popular method is to minimize variance subject to fixed levels of expected ∗Corresponding author [email protected]

We exploit the restrictions of intertemporal portfolio choice in the presence of nonfinancial income risk to design and implement tests of hedging that use the information contained in the actual portfolio of the investor. We use a unique dataset of Swedish investors with information broken down at the investor level and into various components of wealth, investor income, tax positions and inve...

Soccer spread betting is analysed using standard probabilistic methods assuming that goals are scored in a match according to Poisson distributions with constant means. A number of different possible forms of ‘edge’ (betting advantage) is identified. It is shown how the centre spreads of the more common bets in the ‘bet universe’ may be calculated. A more general question is then addressed, nam...
