  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.

  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.
