The paper reviews risk assessment for selection of investments in terms of em-pirical derivation and estimation of beta coefficients on the capital market in Bulgaria. It aims to develop some theoretical aspects regarding risk assessment for investment se-lection as well as to provide empirical derivation and trend analysis of the beta coeffi-cient values of leading Bulgarian public companies included in the SOFIX index. The paper is structured in four main parts according to its subject matter, goal and objec-tives. The first part reviews the current objectives and the theoretical grounds of in-vestment management. The second part focuses on the possibilities to include risk into the investment analysis. The third part analyzes the methodological framework for in-vestment selection. The fourth part presents an empirical study of the beta coefficients of the SOFIX companies for the period 2007-2012, identifies trends and proposes cor-porate grouping according to their capacity to restore market capitalization to the pre-crisis levels. The results show that two of the leading Bulgarian companies (i.e. 13.3% of the total number of companies in the index) have betas exceeding 1.25 (based on monthly data for the period Sept. 2007 - Sept. 2012), seven companies (46.7% of the index) have beta coefficients between 0.75 and 1.25 and six companies (40% of the index) have conservative betas of less than 0.75.

  SIGNAL PARAMETERS OF SHADOW ECONOMY IN BULGARIA

  The global financial and economic crisis at the beginning of this century resulted in certain cataclysms with destructive effects on the government's financial policy.

The global financial and economic crisis at the beginning of this century resulted in certain cataclysms with destructive effects on the government's financial policy. In-creasing government budget deficits, strikingly inadequate social status and deteriora-tion of the basic macroeconomic indicators measuring the „pulse” of the national and world economy once again brought forward the issue of the scale of shadow economy. The presence of shadow economy is an indicator for the lack of trust in govern-ment's financial policy and the inefficiency of the national economic policy. At the same time shadow economy practices affect negatively the economic growth, efficiency of labour, competitiveness and the economic and financial policy of the state. In this context, the main goal of the study is to analyze the extent of the shadow economy and the issues related thereto as well as to examine its actual manifestations in Bulgaria and propose measures to mitigate it.

  NEOCLASSICAL AND INSTITUTIONAL SYNTHESIS OF HOUSEHOLDS

  The paper presents a study on households as subjects of economic relations in terms of the institutional and neoclassical synthesis.

The paper presents a study on households as subjects of economic relations in terms of the institutional and neoclassical synthesis. Households are considered a pri-mary component of the economic system, as well as objectively necessary and relatively autonomous economic entities. The neoclassical synthesis deals with two main charac¬teristics of both individuals and households – their rationalism and sovereignty – as key factors of their behaviour in a market economy. In response to the shortcomings of the neoclassical theory, the institutional approach focuses on the norms, rules and stereo¬types that govern human behaviour in real life. The analysis of households as functional socio-economic entities requires a combination of the concepts of neoclassical and in¬stitutional approaches.
