The modern business environment is characterized by dynamism and constant changes, which are primarily reflected through accelerated technological development, growing competition on the market and increasing expectations and demands of consumers. In such a context, company management becomes one of the key factors that determines the business success and competitive advantage of the organization. The aim of this work is to investigate the role of management in modern companies through the analysis of relevant theoretical approaches and previous research, without relying on own empirical data. Special attention is paid to strategic planning, human resources management, implementation of innovations, as well as the company's ability to adapt to changing and unpredictable business conditions. The paper also highlights the main challenges that managers face in practice, providing recommendations for improving managerial functions, improving organizational efficiency and encouraging innovation. The analysis points to the importance of an integrated approach to management, which combines traditional management methods with modern concepts and practices, thus contributing to the sustainable development of the company and strengthening its strategic capacities.

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.

The aim of this paper is to carry out an analysis of the impact of the monetary and credit policy on the real economic flows in the Republic of Serbia. In order to answer to the given goal, a correlation and regression analysis was performed for the period from 2004 to 2020. The results of this analysis have shown that there is a strong influence of the monetary and credit policy on the gross domestic product of the Republic of Serbia. Based on the results of the conducted regression analysis, it was found that in the Republic of Serbia, with the growth of the monetary aggregate M2 by 1%, gross domestic product grew by 0.691%. It was also found that the growth of approved long-term loans by 1% had a positive impact on the growth of gross domestic product by 0.425%. These values point to the great importance of the monetary and credit policy on economic growth in the Republic of Serbia and the need to attach great importance to monetary policy in the future period.

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.
