  ASPECTS OF THE INTERACTION AMONG FINANCIAL CONTROL INSTITUTIONS IN THE PUBLIC SECTOR OF THE REPUBLIC OF BULGARIA

  There are several control institutions in Bulgaria whose common subject is public finance. These are the Bulgarian National Audit Office, the Public Financial Inspection Agency, and the Internal Audit Directorate. The fact that these bodies have a common subject of control implies uniformity of the control they exercise as well as the ... There are several control institutions in Bulgaria whose common subject is public finance. These are the Bulgarian National Audit Office, the Public Financial Inspection Agency, and the Internal Audit Directorate. The fact that these bodies have a common subject of control implies uniformity of the control they exercise as well as the establishment of certain interrelations among them and the coordination of the control procedures they apply. Surveys conducted so far indicate that despite the agreements which these control institutions have signed, there is rather weak cooperation among them in practice. In addition, the volume of information they exchange before initiating control operations is fairly small, which results in duplicating the activities performed in entities which are subject to control. Hence, the lack of coordination and interaction leads to increased costs of financial audit in the public sector and diminish its efficiency. It is therefore necessary to reorganize the communication among bodies engaged in public finance control.

  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.

  TAX POLICY CHALLENGES AS AN ECONOMIC GROWTH FACTOR

  The objectively imposed presence of taxes in government budget plans shows that it's a phenomenon that was and remains the basis for the performance of state functions. All physical and legal entities, regardless of what positions they occupy in the administrative and economic structures of society, conform their behaviour and estimates for the ... The objectively imposed presence of taxes in government budget plans shows that it's a phenomenon that was and remains the basis for the performance of state functions. All physical and legal entities, regardless of what positions they occupy in the administrative and economic structures of society, conform their behaviour and estimates for the future to the on-going state tax policy. The tax policy is objectively related to the production and process of money distribution and reasonably affects the final results of each business and respectively, economic growth. Tax policy is an instrument of the economic growth, which can solve financial, economic and social problems in the process of both collecting government revenue and spending it.
