  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 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 ... 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.

  PAYMENTS FOR PROPHYLAXIS AND REHABILITATION AS A FORM OF RISK PREVENTION IN THE PUBLIC SOCIAL SECURITY SYSTEM OF BULGARIA

  An attempt has been made to substantiate the thesis that the organisational development and improvement of prophylaxis and rehabilitation payments have significant capacity to promote prevention and overcome the consequences of risk as a form of proactive approach to the public social security management.

An attempt has been made to substantiate the thesis that the organisational development and improvement of prophylaxis and rehabilitation payments have significant capacity to promote prevention and overcome the consequences of risk as a form of proactive approach to the public social security management. The study of the opportunities for organisational development and improvement of the payments for prophylaxis and rehabilitation is the main objective of the study. The following specific tasks are set: study of the principles and limitations of the prevention of risk in the social insurance activity; justification of the need for continuing integration and development of prophylaxis and rehabilitation as an element of the Bulgarian social security system; study of the specificity of morbidity and traumatism among insured persons; evaluation of payments for prophylaxis and rehabilitation and formulation of proposals for their organisational development and improvement. The results of the survey confirm the necessity to make payments with a preventive and long-term effect, testify to the achievement of good organisational level of prophylaxis and rehabilitation in the NSSI system and outline the opportunities for their development and improvement. Organisational changes with significant capacity for continued successful integration of prevention and overcoming the consequences of risk as a form of proactive approach to the public social security management in Bulgaria have been proposed.
