  APPLICABLE ASPECTS OF ECONOMETRIC MODELING OF DYNAMIC RELATIONS

  The paper is focused on the application of the statistical methods for the analysis of dynamic relationships. The relationships among the economic phenomena are realized not only in the distributions of the population, (static aspect) but also in the changes that have occurred into it with the time (dynamic aspect). The thesis supported by the ... The paper is focused on the application of the statistical methods for the analysis of dynamic relationships. The relationships among the economic phenomena are realized not only in the distributions of the population, (static aspect) but also in the changes that have occurred into it with the time (dynamic aspect). The thesis supported by the authors is that statistical methods used for the analysis of dynamic relationships are both modern and powerful instruments for the researchers that allow to discover new characteristics of the interdependence among economic phenomenon but at the same time, their application is accompanied with many conditions that have to be known and taken into account. The goal of the paper is to systematize the statistical methods for analysis of relationships based on time series data, and to point out their abilities in the advancement and enhancement of the analysis of the economic phenomenon. In order to achieve this goal, we have solved the following tasks: a) to describe the cross-correlation analysis; b) to characterize the distributed lag models (aka transfer function models); c) to study the vector auto regression (VAR) models; d) to describe the cointegration as advanced statistical method for the analysis of non-stationary time series. The established results cover the advanced features of the dynamic relationship models: the interdependence between two (or more) time series; exploration of single relationships and distributed influence; the representation of multidimensional dynamic relationship; the survey of both long-term equilibrium relation and short-term interaction between the variables induced by the deviations from equilibrium state.

  CLASSIFICATION, EVALUATION AND ACCOUNTING POSSIBILITIES FOR DERIVATIVE FINANCIAL INSTRUMENTS

  The undeniable interest of economic theory and practice towards financial derivatives makes them a current subject of analysis.

The undeniable interest of economic theory and practice towards financial derivatives makes them a current subject of analysis. The existence of derivatives raises the logical question about their purpose. If an investor participates in the distribution of a company’s profits by holding its shares, why do they apply another instrument that is related to owner’s equity? The derivative markets create favorable opportunities by improving the efficiency of the underlying assets markets. Derivatives have lower transaction costs compared to other transactions with basic instruments on the spot market, they are more liquid and the risk can be transferred into a more effective, simple and inexpensive way. Proof for the significance of derivative instruments is also the EU-accepted IFRS 9 Financial Instruments. Therefore, it is important that the management of every organization is aware of the regulatory framework for financial instruments, as well as the effects of each transaction with financial instrument. The main purpose of the study is to define a classification of derivative instruments and to mark key points in their accounting. The specific objectives that have to be solved are to highlight the alternatives for classifying derivatives and to focus on their immediate current accounting. The thesis is that the adequate classification and evaluation of these instruments are important factors for their correct accounting. The main conclusion is that proper classification of derivatives has a practical significance because there has to be determined whether the instrument has a value at the beginning, which has a timely accounting impact. Their internal and time values have a significant role as well, because in the changes they must be clearly distinguished from the change in the fair value of the derivative itself.

  DEVELOPMENT OF COMMERCIAL BANKS BRANCH NETWORK ‒ A CRITICAL EVALUATION OF THEORY AND PRACTICE

This study focuses on commercial banking and the development of branch networks as an essential part of the banking system. At the centre of the analysis is the relationship between the expansion of the branch networks of commercial banks and the influence of the following four factors: the dynamics of the economic development cycle at global, national and regional levels; the processes of consolidation in the banking system; the evolution of information technology and electronic banking and regulatory policy and restrictive measures including insolvency procedures that the central bank establishes in its supervisory capacity for the banking sector. The aim of this study is to offer a critical evaluation of the factors influencing the decision-making concerning the dynamics in the branch network of commercial banks, both at a sector level and in the context of the individual banks. The paper comprises four main parts: Firstly, a critical review of the regulatory system and contemporary scientific studies in the area of bank administration and branch network management, including the structure of decision-making factors in relation to expanding, maintaining or reducing the network of bank branches; Secondly, historical and empirical-applied analysis of the dynamics in the licensed banking institutions and their positioning on the competitive banking market in Bulgaria; and thirdly, analysis of the financial indicators for the banking system and the related trends in the development of the branch network of the commercial banks in Bulgaria and their staffing. As a result of the study, it has been confirmed by the empirical data for the Bulgarian banking market that after 1989 the dynamics in the branch network was originally due to the dynamics in the creation and merger of banking institutions. During the period of EU membership, this process has been based mainly on the key factors developed with the priority of the regional demand and supply of banking services. About the two leading banking institutions, in terms of bank staff numbers, number of branches and personnel per branch for the two leading Bulgarian banks, the analysis has shown the following results: 3049 people, employed in 173 branches with a 17.6 average number of employees per bank branch for Unicredit Bulbank (data relating central management as well) and respectively, in the system of DSK Bank - 4115 people with an
