Investment Portfolio Risk Assessment on the Basis of Hierarchical Model

Introduction. Efficiency of investments is an important factor at the micro- and macroanalysis of economy, investment in venture capital depends on the development of firms, regions, States. Especially actual this problem for portfolio investment. The aim of this work is to develop a new minimax method for modeling the dynamics of risk of portfolio investment, which allows to assess the distribution of equity is a structural component of a financial portfolio.

Methods. Suggested new method for modeling and rationalizing the structure of equity investments using the minimax criterion. Drill through the decision of the investor as from the original portfolio preferences, specific risk assessments for each lower level in the hierarchy (topdown) and a calculation of expediency of inclusion in the portfolio of each asset of the lower level, with specific risk assessments (bottomup), which is consistent with the approaches of fundamental analysis of securities market. Provided step-by-step algorithm for grouping, clustering and data analysis along the branches of the hierarchy.

Results. Is developed the scheme the implementation of the model for a three-tier structure for complete binary decision tree. Is given the iterative computational algorithm and its implementation.

Conclusion. The recommendations can be applied to rationalize the funding of innovations that improve the quality of development of regions in the rehabilitation plan for selected executives of corporate sector.

About the Modeling of the Shared Structure of Finances Using the Minimax Criterion of Laboriousness

Introduction. Being one of the main parts of financial management, good bonuses for the employees will lead to a stable business development. This is particularly relevant issue for service businesses, where the business is built on competent staff and their material interest in improving the quality of services is the possibility to the prosperity of the business. When financial manager analyzes sources of bonus payments to employees, it is necessary to rationally justify the current size and the standard premium for each employee and different groups of workers. This article proposes a new method for funding of bonus pool, which allows the assessment of the distribution structural component of equity premium payroll for several categories of workers with fundamental differences in productivity. Methods. A new method of modeling and rationalize the equity structure of the funding of the bonus pool workers of different categories using the minimax criterion of quality. Apply methods of cluster analysis, in particular, the grouping method and the normalization clusterizing data. Provides step-by-step algorithm of recommended actions to rationalize premium payments. Results. A new mathematically grounded approach to the rationalization of the bonus Fund, which allows to consider both the psychological characteristics of decision-makers employer and the rationalistic position by applying as estimated negative for groups bonuses not only traditional indicators of labor, but also individual characteristics, endurance, productivity, new ideas. Also have the option of structuring costs in the analysis groups «superior – subordinate» given increased responsibility first. Conclusion. Developed a new approach that allows for the rationalization of premium payments in any enterprise, especially relevant for enterprises, where workers receive wages as percentage of revenue, and differentiate rates for various categories of employees is quite difficult
