This article deals with the under-researched phenomenon of rural health entrepreneurship and its major characteristics. The purpose of this study is to explicate the process of providing health services in rural areas of a developing country and their relation to SDGs. The paper is based on six semi-structured interviews conducted with Serbian health entrepreneurs in rural areas (two private practices, two policlinics, and two dental practices), a review of laws and strategies relevant to the field, and three sessions of discussions with eight experts (four authors and four additional experts). The research methodology follows an empirical, mixed-method case study research procedure. The results are presented in relation to the aspects of frugality, family orientation, and sustainability-oriented innovation. The timeline of the six case studies demonstrates the increasing importance of health entrepreneurs in rural areas due to the aging population and, therefore, increased needs for quality healthcare in these areas. The financing instruments have also become more formal and substantial in recent years, enabling the growth of healthcare businesses in rural areas. However, a major obstacle to further sustainable development remains the non-refundability of services before the state-owned, obligatory health fund, creating major social inequalities, especially in rural areas.

Modern technologies offer many opportunities to companies everywhere in the world. Marketing's and manager's job is to get to know all those possibilities, to know their positive and negative side, put it in context and use it in marketing strategy in order to upgrade business of the company, improve sales effectiveness, and finally, raise revenues and value for all stakeholders. This paper contains data on using social networks and technology in advance in company actions, so informations are firstly collected using Facebook, Twitter, Instagram, Google+, Pinterest, LinkedIn, and other social platforms, and the same networks are used to spread informations about business and products, along with feedback used to correct future actions. Informations gathered can be extremely useful, but some can be recognized as unneeded. The main goal of this paper is to show how social networks influence modern businesses and how they can be used as a part of marketing mix in order to improve business effectiveness.

The aim of this paper is to show whether the current system of environmental taxation and environmental policies of the states is efficient for solving environmental problems. We analyze the link between environmental tax revenues and total government expenditure as independent variables and government expenditures for environmental protection as dependent variable in selected EU countries. By the implementation of panel data regression analysis on a defined sample, we came to the conclusion that among the observed variables there is a positive relationship. However, this relationship shows that the growth of expenditures for environmental protection is slower than the growth of total expenditure. The results also suggest that the relationship between revenues from environmental taxes and expenditures of the state in the area of environmental protection is a little weaker. With respect to the result of the analysis, it can be concluded that the existing state policy in is not sufficiently effective.

This paper aims to answer the question of whether import and export have a positive impact on the movement of the gross domestic product in selected countries of the European Union (EU). In the paper, a panel data regression analysis has been applied in the EViews 8 software package. In countries with a high level of income that were selected for analysis, a positive relationship between the observed macroeconomic variables by determined which is statistically significant. The results showed that imports had a greater impact on the gross domestic product than exports in the selected countries for the observed period.

In modern conditions, human society is faced with numerous environmental problems, which call for necessary action in order to ensure sustainable development. In other words, solutions to environmental problems are urgently needed if we wish for future generations to have the same quantity and quality of resources that the current generations possess. Countries around the world, and especially EU member states, place a strong focus on environmental issues, and as one of the basic instruments in resolving them, they use environmental taxes. These taxes are intended to make polluters lower their pollution levels in order to reduce their tax burden. Among other things, they encourage polluters to invest in ecological innovations, all with the aim of reducing the tax burden and increasing the quality of the environment in the future. The aim of this paper is to establish how strong the influence of environmental taxation is on the development of ecological innovations. For this reason, correlation and regression analysis were used on a sample of EU member states. The obtained results show that the influence of these phenomena, i.e., variables, is positive and strong and that with the growth of income from environmental taxes per capita by 1%, the index of ecological innovations increases by 0.663 with a significance level of p=0.000.
