Abstract Economic shocks represent a challenge for health systems because they decrease public revenue, and at the same time, increase the need for publicly funded health care. Since health expenditure is rapidly increasing in most countries, its efficiency must be tested. The subject of research in this paper is exactly the interdependence of public health expenditures and their efficiency, expressed through the anticipated life expectancy, as well as their relationship with economic growth. The correlation analysis conveyed in this paper refers to the period 2010-2019 and it is based on OECD countries’ data, growing OECD economies data, and the data for the Republic of Serbia..

Abstract Brands that have highly loyal consumers are in the function of the identity and image of their personality. The primary drivers of loyalty to such brands are the intangible characteristics of brands that have a certain symbolic meaning for consumers. In that sense, brands are in the function of articulating consumers as personalities and achieving an appropriate image. To achieve this, brands are often considered individuals who, like consumers who buy them regularly, have similar characteristics. If the characteristics of brands and the characteristics of consumers are more harmonized, consumers will be more loyal. Starting from the above, the aim of the author is to investigate the influence of brand personality dimensions on consumer loyalty to two groups of products: mobile phones and cars. The research was conducted on the territory of the Republic of Serbia. The results of the research are essential for brand management because they represent guidelines for undertaking certain activities in building brands with a leading position in the market.

Abstract This paper investigates the intercompany-specific characteristics as a determinant of the sustainable growth rate. We researched a sample of companies listed on the Macedonian stock exchanges. We found that the average actual growth rate for the 2010-2019 period is only 0.38%, while the sustainable growth rate was 1.42%. This is because of the poor operating performance of the companies, moderate leverage, and average retention ratio of 82.5% for the whole sample. The actual growth rate in specific years is drastically higher than the sustainable growth rate, while in certain years it is negative. The sustainable growth rate is positively affected by the profit margin, retention ratio, asset turnover, financial leverage, and ROE, and it is negatively affected by the operating cash flow, company size, growth opportunities, and non-debt tax shield.

Abstract Due to the influence of numerous factors that make it difficult to find the innovative solutions to social and environmental problems that social enterprises deal with, there is a need for a joint action of social enterprises, both with each other and with other actors operating in their environment. In order to overcome the challenges more easily, which they face in their business, social enterprises and social entrepreneurs should take advantage of networking. Business networks can bring many benefits to their members, and networks in the social sector are of particular importance. Recently, networking has taken place within the broader framework of so-called ecosystems. With this in mind, the aim of this paper is to shed more light on the specifics of networking of social enterprises, i.e. their connection to ecosystems. The Social Entrepreneurship Network (SEN) has played a key role in the development of this sector in European countries. Also in the Republic of Serbia, networking of social enterprises with civil society organizations has significantly contributed to the creation of public policies and the promotion of social enterprises.

Abstract Auditing firms are very important for business decision-makers and they have a large impact on business development, due to issued reports and competent opinions contained in such reports. The purpose of this paper is to present, to professional public, the current condition and changes of business results achieved by active auditing firms in the Republic to Serbia over the period of eleven years. The goal of the paper is an objective assessment of the state of play and operations of active auditing firms, as well as a determination of business trends and monitoring of the results achieved in the audit services market. The paper analyzes the changes in individual balance sheet items and profitability indicators, that is their average growth during the eleven years. The results indicate that the members of the "Big Four” had not acquired a leadership position in the market, observed according to the productivity indicators. Actually, the results indicate that the auditing firms with the largest growth of net results, in the observed period, are not the leaders according to the criterion of assets growth. At the same time, the firms with the greatest growth of business income in the observed period are not at the same time the most productive firms, measured by net result per employee. The results obtained in this paper contribute to the formation of a realistic view of the situation in the audit services market, as well as the perspectives and tendencies in the development of audit firms.

Abstract The purpose of this study is investigating the homogeneity of the European Union countries (hereinafter: EU countries) according to the achieved level of environmental performance in agriculture and climate change in 2020. The data used for this study are from an internationally comparable database. For the purpose of validation of the laid hypothesis, methods of statistical analysis were employed. The study focuses on Climate change and Agriculture, two factors of the Ecosystem Vitality component, which will be considered in more detail, as well as the indicators included in the Environmental Performance Index (hereinafter: EPI) structure. The empirical findings revealed the existence of a medium and a positive quantitative agreement between the two environmental policy areas, agriculture and climate change. Also, the cluster analysis showed that most of the countries selected for the research apply agricultural production with controlled use of nitrogen, which further affects the reduced emissions of greenhouse gases and thus minimally contributes to climate change.

Abstract This paper uses dynamic panel data methods to examine the political indicators and governance quality indicators as determinants of foreign direct investment (FDI) into the Balkan and non-Balkan countries in transition. Our empirical model shows that the determinants, such as political terror scale and the control of corruption, have significant and plausible effects in the Balkan and non-Balkan countries in transition. In addition, analyzed factors such as government effectiveness and regulatory quality, which play important political roles in determining foreign direct investment flows into countries in transitions and help explain the differing attractiveness of individual countries to foreign investors in our empirical model, do not play a significant role in the inflow of foreign direct investment

Abstract Given that data and information have become the most valuable assets of companies that can be efficiently and economically stored in the cloud infrastructure, there is great pressure on business entities to capitalize on this business and technological opportunity. There is a particular pressure on oil companies to find new ways to create a competitive advantage by using the opportunities offered by cloud-based businesses. This is primarily a result of the fact that the reorientation of business activities to this type of storage and integration of data and applications represents a major change in the business world, and the growth trend continues in all aspects of the business. This paper deals with the possibilities and challenges of applying cloud technology in oil companies operating in turbulent conditions caused by fluctuations in oil prices in the global market..

Abstract The role of international trade was irreplaceable at the start of the COVID-19 pandemic crisis, especially the trade in medical supplies and food for all affected countries. Trade as a part of this crisis, certainly should not be an element of further countries` closing and new trade barriers implementation. On the contrary, it could be a way to exceed these problems, especially if all participants in the trade point out the same aims of the normal trading during the pandemic crisis and implementation of Trade Facilitation Agreement provisions. The effects of Trade Policy measures during the COVID-19 crisis and their relation with the Trade Facilitation Agreement were analyzed in this paper. Trade measures applied at the beginning of the crisis have dual character, trade facilitating and trade restricting. This paper highlights the tariff reduction and non-tariff barriers decrease, as possible approaches for the trade policy. The aim of this paper is to show the extent to which the TF agreement, ratified recently, could be applied during the time of the pandemic. This paper provides an overview of a number of trade policy measures that have slowed down the implementation of this agreement. It also points out the role of this agreement, as one of the most important instruments that could be used to expedite the movement of goods, which is especially necessary during the pandemic.

Abstract The first systematic definition of economics in Western culture takes place in Aristotle’s Politics. In the first chapter of this writing, Aristotle analyzes in detail the skill of household management (economics). When he tries to see the same skill not only within the household, but also in the context of the political community (polis), Aristotle notices problems that arise with the development of the skill of acquiring property (κτητικὴ) and the skill of acquiring wealth (χρηματιστικήν). The application of the principle of household management to the political community leads to fundamental problems, fundamentally unsolvable, due to which the economy and politics in the political community (polis) remain in permanent tension.
