  INCOMES, CONSUMPTION AND ECONOMIC GROWTH

  Eeconomic growth can be influenced by a number of factors, but certainly among the most important ones are the incomes and consumption of the population. An increase in incomes leads to increased consumption, which in turn, stimulates pro-duction, i.e. the creation of more goods and services and therefore causes an increase in the volume of gross ... Eeconomic growth can be influenced by a number of factors, but certainly among the most important ones are the incomes and consumption of the population. An increase in incomes leads to increased consumption, which in turn, stimulates pro-duction, i.e. the creation of more goods and services and therefore causes an increase in the volume of gross output and therefore gross value added. In the process of implementing the project task we had to thoroughly analyse the triad of „income-consumption-economic growth”. We also processed a large amount of statistical information, analyzed data obtained from surveys and studied the research of Bulgarian and foreign authors.

  EQUILIBRIUM IN STOCHASTIC OPTIMIZATION MODELS WITH ECONOMIC APPLICATIONS

  The subject of this work is the application of a linear quadratic model which is a result of the stochastic modeling process in the economic field. 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 ... The subject of this work is the application of a linear quadratic model which is a result of the stochastic modeling process in the economic field. 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.

  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.
