It is examined analitical statistic and dynamic models for choice of decisions for realizing of the firm’s investment activity in short and long lasting plan. It is analyzed the necessaryly economic data and parameters at the composing the investment behavior. It is studyed and refined different dinamic optimizing models by means of them are defined the relation between inovation and investment and interaction between investment and marketing firm’s politics. It is given models with distributed lags for describing the nvestment. It is developed dynamic optimizing models for determining of the investment firm’s politics in our country. By means of its are fined the investment technical structure, bringing to perfection using the production factors at reporting of the accidental factors.
It is examined the problems, connected with the Methodology for improving of the Homogeneity of the statistical information for production evaluation in connection with its perfecting in accordance with the Eurostat Requirements. It is suggested different approches for making of the statistical units for an observation with the purpose of improving of the Homogeneity of its conformed information. It is showed the influence of the Underground Economy and the Inflation on the Homogeneity at evaluation of the output. It is elaborated some methods for measuring of the Underground Economy for branches and for all Economy in connection with the improving of the Homogeneity for the assessment of the production results. It is examined a lineal model and model for transforming of the input/output matrix indicators by means of factor for the value with reading time factor and rate of the inflation at the determination of its value for reaching of the product Homogeneity and Homogeneity of its monetary assessments in the System of the national accounts.
In this scientific investigation a model is developed and applied for the comprehensive evaluation of the competitive power and competency of specialists in a specific firm (enterprise, institution and so on). The different criteria used in this assessment and example contents of these criteria are noted. The evaluation is performed by utilizing 6 degrees. The indicators used in the study are assigned different values which depend on the importance of the results obtained from a specific specialist working in a specific area. The specialist’s competency is calculated using a complex assessment which simultaneously uses 138 indicators. There are possibilities for applying the methodology developed when evaluating the competitive power of products which are produced by companies with different types of production and when evaluating this at both a regional and national level. The methodology can be computerized and can be applied by collecting the information, and the different criteria in these indicators constitutes the characteristics of the specialist, product, company, municipality, region and so on.
It is described the production boundaries in the System of National Account (SNA) and it is pointed the ways for their taking in its. It is considered the structuring in according to economics activities and institutional units. It is investigated the economics structure of the SNA and embracing basic blocks and systems. It is done cognitive analysis of the structural sections by means of the production is enveloped. It is pointed the difficulties at the formulation of the tables and accounts and the reasons, from which they are arisen.
Theoretical and applied problems of the correctness at evaluation of the output in the System of the National Account (SNA) are examined in the study. It makes experiments to elaborate and to put in to practice different methods for improvement of the correctness at the evaluation of the output. First, it is examined the theoretical problems connected with pure branch, the units in the SNA, the inflation and the import output. Second, it is given different proposals for using these methods in the statistical practice as is pointed their priorities.
This paper formulates the concept for the hidden economy. A refine on the formal and the informal economy is made. It indicates the economic, administrative, normative-legal factors and reasons for its existence and the forms for manifesting of the hidden economy. It discloses the condition of the hidden economy in some West European and post-socialist countries and USA too. It gives different methods for measurement of the hidden economy that are concerned with the Bulgarian conditions.
In the study are examined problems, concerned with the manifestation of the hidden economy in Bulgaria in different periods of economic development. It is elaborated and applied different methods for evaluating its quantity for the Bulgarian conditions. It is revealed its influence on developing of the country’s economy. They are described the economic and the social consequences and they are indicated different practical examples in front of the management, aroused by the hidden economy.
