• Portfolio optimization in the case of an exponential utility function and in the presence of an illiquid asset

  ... is going to infinity. We show that the optimization problem with the exponential utility function is not connected to the optimization problem with the HARA utility by the limiting procedure and we obtain essentially different results. We provide the Lie group analysis of the corresponding HJB equation. For the main three-dimensional PDE with the exponential utility function, we obtain the complete set of the nonequivalent Lie group invariant reductions to two-dimensional PDEs according to an optimal system ...

• Russian Northwest: An integral Assessment of the Conditions of Regional Social, Environmental and Economic Systems and Quality of Life

  ... Moscow region. The authors examine the QOL in 10 NWFD regions, including the Baltic ones. The significance of the research work lies in an integrated and comprehensive assessment of the regional SEES and QOL in 2006, 2009, 2012, and 2013 in view of the effect of priorities within and between groups of assessment parameters. Another important result is the identification of ‘stability limits’, when regions retain ... ... The proposed methodology is based on multi-criteria and integrated approaches, the aggregate index method, and the parameter analysis and synthesis. The assessment of SEES and QOL was performed for five classes (from ‘1 — high’ to ‘5 — poor’) ...

• An environmental analysis of the red-backed shrike’s and barred warbler’s nutrition in the conditions of sympatric habitation in natural and anthropogenic stations

The main dietary differences between these species lie in the foraging tactics: ambushing in the red-backed shrike and searching in the...

• Demographic Ranking of the Baltic Sea States

  The relevance of the study lies in the acute need to modernise the tools for a more accurate and comparable reflection of the demographic reality of spatial ... ... major demographic coefficients relative to the age structure.The article describes the first attempt to apply the method to the analysis of birth and mortality rates in 1995 and 2010 for 140 countries against the global average, and for the Baltic Sea states against the European average. The grouping of countries and the analysis of changes over the given period confirmed a number of demographic development trends and ...
