  DEBT AND MACROECONOMIC VARIABLES IN THE CONTEXT OF THE “EUROPE 2020” STRATEGY

  Theoretical formulations about the nature, characteristics and directions of influence of government debt and government deficits on the main macroeconomic variables are clarified. The size, dynamics and maintenance of all financial obligations undertaken by and on behalf of the state, representing the obligation of the state, covering internal ... Theoretical formulations about the nature, characteristics and directions of influence of government debt and government deficits on the main macroeconomic variables are clarified. The size, dynamics and maintenance of all financial obligations undertaken by and on behalf of the state, representing the obligation of the state, covering internal and external debt are analysed. The dynamics and trends of change in government debt and its relationship with key macroeconomic variables are studied.

  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.

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.
