The structure of the portfolio of insurance companies shows what consumer preferences to different insurance products are. The comparison of product structures makes it possible to determine whether there is a change in the pattern of insurance consumption, to outline the reasons if there is a change and insurers to take adequate actions in line with new trends in consumer demand.
The objective of this article is to assess the strength of the structural changes in the product portfolio of Bulgarian insurance companies. The assessment of the structural changes is done by tracing the dynamics in the distribution of Gross Premium Income by insurance sectors and insurance classes and also on the basis of the values of the integral coefficient of structural changes. The thesis defended is that tracking changes in the product structure makes it possible to identify the dynamics of the market shares of the insurance sectors and the insurance classes, to outline the trends in their market positions and to assess the degree of change in the consumer preferences.
In order to achieve the objective and to prove the thesis, the following tasks have been formulated: formation of the structure of the insurance market by calculating the market shares of general and life insurance; formation of the structure of the product portfolio in general and life insurance by calculating the market shares of different types of insurance; establishing the changes in the positions of the individual insurance sectors and insurance classes in the product structure; characterizing the strength of the outlined structural changes.
The survey results show that there have been changes in consumer preferences for different insurance products during the period under review. The changes in the product structure of life insurance are the most significant.

The research area of the survey is the balance sheet positions of the BNB, and the subject - the convergent aspects of the BNB balance sheet items for the period 01.2006 to 03.2018. The purpose of the survey is to identify the specifics, under the currency board conditions, as well as the dynamics, trend and risk parameters of the BNB balance sheet items, focusing on the currency risk of USD-denominated balance sheet positions and the correlation of these positions with the GDP of Bulgaria. A special focus is placed on currency risk in USD-denominated balance sheet items. The thesis tests the existence of a direct link between dynamics in the BNB balance sheet positions and the growth of GDP, taking into account force majeure factors. The paper has the following tasks: first, study the philosophy and the regulatory framework for the structure of the balance sheet items of the BNB; study trends and dynamics of the balance sheet positions of the BNB for the period 2006-2018; thirdly, the study of the currency risk system and its effect on the balance sheet positions of the BNB; the study of the correlation relations and the influence of the passives on the active positions in the balance sheet of the BNB. Analytical results confirm leadership "risk" status for the item "Cash and cash equivalents ..." (by 61.7% of the variation) in the asset and under "Liabilities to other depositors" the liability (61.7% variation). The final correlation analysis of the relationship between dynamics in capital and liabilities positions and their impact on asset positions places a leading role as a factor of position „Total Liabilities“. The impact of its dynamics is the strongest on „Investments in securities” with a positive correlation from +0.76 and determination coefficient equal to 57.9%.

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 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.
