  EFFICIENCY AND ECONOMIC GROWTH OF INDUSTRIAL BUSINESS UNDER CONTEMPORARY CONDITIONS

  The issues related to achieving smart and sustainable growth by efficient and environmentally-friendly use of resources are fundamental in „Europe 2020” strategy and „Bulgaria 2020” National Programme. The relationship „efficiency – economic growth” is interpreted in accordance with the ideas of these programs. The possibilities for analytical ... The issues related to achieving smart and sustainable growth by efficient and environmentally-friendly use of resources are fundamental in „Europe 2020” strategy and „Bulgaria 2020” National Programme. The relationship „efficiency – economic growth” is interpreted in accordance with the ideas of these programs. The possibilities for analytical evaluation of capital and human resources and economic growth are ex-amined. Practical research was carried out on the extent of resource utilization and its impact on economic growth of industrial enterprises from different sectors, which largely illustrate the peculiarities of development of industrial business in the period 2007-2010.

  INSURANCE AND SOCIAL INSURANCE IN THE CONTEXT OF THE ECONOMIC PROFILE OF SOCIAL SECURITY IN A MARKET ECONOMY

  A widespread understanding connects the individual, respectively social security, too, with reaching the state of a guaranteed opportunity for meeting a particular level of socially accepted human needs in all life situations, including ones caused by contingent risks accompanying one’s daily life. Presented in such a way, this security has ... A widespread understanding connects the individual, respectively social security, too, with reaching the state of a guaranteed opportunity for meeting a particular level of socially accepted human needs in all life situations, including ones caused by contingent risks accompanying one’s daily life. Presented in such a way, this security has distinct economic dimensions. In a market economy, social insecurity of individuals increases. This brings to the foreground problems related to individuals’ security. Those who are competent to solve these problems are insurance companies, as well as pension and health insurance companies, whose activities in the outlined trend are the subject of the current research, first of its kind for the Bulgarian theory and practice.

A dynamic economic process is modeled, which occurs in conditions described by a stochastic differential equation. The dynamics of the process is subject to jump-like changes. Such systems are known as Markov jump linear systems. The target in the observed process is modeled through a functional which has to be minimized. The result is a linear quadratic stochastic model. The equilibrium search model is related to the numerical solution of a system of generalized discrete-time algebraic Riccati equations. Methods for finding the maximal solution to a system of discrete-time algebraic Riccati equations are investigated. Moreover, new methods and algorithms for computing of this maximal solution are proposed. The numerical characteristics of algorithms are analyzed in special cases of negative definite weighting matrices and indefinite weighting ones. Conclusions are derived of the applicability and efficiency of the proposed methods.
