This study focuses on the most prominent theories about modeling economic growth. The factors of economic growth in Bulgaria are studied in terms of econo-metrics. The main determinants of growth are identified and the strength of their impact is measured. The positive multiplier effect of final consumption, gross capital formation, government expenditures on employee compensation, exports and unilateral gratuitous transfers are determined. Opportunities for stimulating economic growth in Bulgaria are analyzed in the short and long run.

  CHALLENGES FOR BULGARIA'S AGRICULTURAL SECTOR IN THE SECOND DECADE OF THE XXI CENTURY IN THE CONTEXT OF THE EU COMMON AGRICULTURAL POLICY

  Òhe EU Common Agricultural Policy focuses on efficient and sustainable agriculture. The growing challenges facing agriculture in Europe (including Bulgaria) necessitate that it is continually reformed so that it can comply with society’s higher demands for healthy food, preserving rural areas, ensuring high quality products and maintaining ... Òhe EU Common Agricultural Policy focuses on efficient and sustainable agriculture. The growing challenges facing agriculture in Europe (including Bulgaria) necessitate that it is continually reformed so that it can comply with society’s higher demands for healthy food, preserving rural areas, ensuring high quality products and maintaining farmers’ incomes. „The European model of agriculture” aims to create sustainable agricultural practices, to ensure the overall market orientation of agriculture and to enable farmers to benefit maximally from the market abilities to deliver products demanded by consumers.

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.
