Until the early 1920s, the classical theory of price included two main models, perfect competition and monopoly. However, E. Chamberlin and J. Robinson introduced a new theory of monopolistic competition in 1933. At the time of global economic crisis, when only the most powerful companies survive, the model of monopolistic competition is hardly sustainable. In fact, the most widespread market model in highly developed world economies has been replaced by monopoly. Supply reduction due to the bankruptcy of many companies, combined with demand decline as a result of the austerity measures, and on the other hand growing need for higher budget inflows, lead to the price hikes in all industries. All mentioned result lead to an extreme market model – the monopoly; even in countries that were known as market economies and by its monopolistic competition. Furthermore, it is well known that employment level is lower in economies that are not competitive. That fact additionally contributes to conclusion that the sustainability of the monopolistic competition is almost impossible during the crisis, considering that we have witnessed high unemployment rates in some EU countries (e.g. Spain, Greece, Italy, Portugal and Ireland). The subject of this paper is to explore sustainability of the market model of monopolistic competition in conditions of the global economic crisis, transitional economies and the reform, under which is a public sector of the Republic of Serbia. The aim of the paper is to determine are there any opportunities for the survival of the mentioned market model in terms of re-industrialization, which is inevitable companion of globalization.

The research performed in this paper refers to the model that would be used to analyze the effects of the implementation of Planning, Programming, Budgeting and Execution Process (PPBE) on the budget of the Republic of Serbia defence system.

In a specifically defined environment, while recognizing international experiences in implementation of PPBE, the model is actually a methodology for solving the abovementioned problem. It may be defined as a process for creating a model of an actual system and conducting experiments, which enables understanding of the system behavior and/or evaluation of different strategies for system functioning.

The realization of the goal of price stability, the central bank, according to the accepted consensus before the crisis, should have complete independence in decision-making. The possibility of full independence of the central bank has raised many controversies. The main argument of complete independence was to establish a central bank authorities according to law. This allows them to impose duties, responsibilities and define the mandate and thus directly or discreetly affect its operation. The latest crisis has shown that the central bank from political pressures have taken a number of non-standard measures in alleviating and limiting the crisis. Sovereign debt crisis in the EU has more impact on the independence of the central bank. Therefore, central banks have to immediately normalize its business back into the legally defined boundaries and achieving its main objectives. Long-term monetary "hospitalization” may undermine the credibility and independence of the central bank. Therefore, they should be independent from the legislative and executive branches.

In recent decades there is constant growth of female enrolment in the higher education in Europe, but it is generally observed that such trend is not reflected in the labour market. The goal of this paper is to present the Absorption Index (AI) as an indicator for dynamic comparison of female participation in tertiary education and their later participation in work force. The main purpose for introducing this indicator is to identify the countries with successful labour markets when it comes to the employment of women with tertiary education. The general conclusion is that the growth of female students is faster than employment growth and as a consequence there is increasing number of unemployed female with tertiary education in the labour market.

In this dissertation, we aim to clarify the concept of calculating risk and return portfolio. Possible outcomes of the investment are usually distinguished from permanent investors' expectations, and it is very important to have a complete picture of the observed variables. The level of the average deviation from the expected yield potential is really important in making the decision on entry into a particular investment because it determines the amount of surprises that may arise from these investments. The yield of the company achieves or does not achieve, depending on the success of a combination of many factors . The starting idea of previous expenditure generated over at least return rate of time preference values for the abandonment of potentially favorable alternative uses in real life, manifests itself as a theoretical construct that accepts that there is the risk-free investment yield for which the risk is zero , and that the minimum return to the investor still counting . However , the problem is that all investors are the same. There are investors who still think of the risk-free rate and investors who do not think about the risk but only on yield and the best yield alternatives. Of course , in any case the risk is an unavoidable component that expects investors . An investor who prefers high- risk class is always exposed to the danger that the result will not make any refund nominal investment, nor any yield.

Nowadays different national accountant practices cause numerous problems in international financial reporting. Those problems are caused by the fact that financial reports prepared and made according to the principles and rules of recognition, measuring and publishing on national level do not correspond to the users of other national economies. Тhis is the reason why cоmpanies are forced to translate, that is make financial reports produced in one national economy in accordance with the rules of the other national economy. Companies are thus facing the problem of financial reports preparation and creation, because different accounting practices enable comparison of financial reports. This is especially expressed in making investment decisions in international financing.

The mentioned weaknesses originate in the idea of unlimited liberalization of financial markets, with minimal regulation and weak business control of the investment banks and funds.

The authors talk about the health, pension and social security. These three sub-systems of social security are seen through the current legal framework, which consists of three laws: the Law on Health Insurance, the Law on Compulsory Social Insurance and the Law on Employment and Unemployment Insurance.

Global companies are strongly pressed by the need to simultaneously and equally efficiently manage globally, since the whole world for them is a single market, and locally, due to the fact that the world market makes a number of different and poorly connected markets.
