Opis: We propose a new coloring game on a graph, called the independence coloring game, which is played by two players with opposite goals. The result of the game is a proper coloring of vertices of a graph G, and Alice’s goal is that as few colors as possible are used during the game, while Bob wants to maximize the number of colors. The game consists of rounds, and in round i, where i = 1, 2,, … , the players are taking turns in selecting a previously unselected vertex of G and giving it color i (hence, in each round the selected vertices form an independent set). The game ends when all vertices of G are selected (and thus colored), and the total number of rounds during the game when both players are playing optimally with respect to their goals, is called the independence game chromatic number, χig(G), of G. In fact, four different versions of the independence game chromatic number are considered, which depend on who starts a game and who starts next rounds. We prove that the new invariants lie between the chromatic number of a graph and the maximum degree plus 1, and characterize the graphs in which each of the four versions of the game invariant equals 2. We compare the versions of the independence game chromatic number among themselves and with the classical game chromatic number. In addition, we prove that the independence game chromatic number of a tree can be arbitrarily large.

Opis: Globalisation “takes” its victims, which the authors believe means that the future of small- and medium-sized towns has become uncertain in Europe. The role of centres is continuously increasing, and most researchers prefer to analyse the competitiveness and innovativeness of metropolitan areas. In this study, we characterise the small- and medium-sized towns in the central–eastern European region as well as explore their possible development path. The authors are convinced that one way for these towns to survive is through strengthening of innovation abilities, which means increasing the innovation performances of economic stakeholders and new forms of interaction among other institutions in order to handle social problems. The theoretical starting point is the interpretation and presentation of the micropolitan (without big towns) regions as well as understanding the concept of technological and social innovation. As the result of the research, the innovation measurements carried out in some of the settlements will be represented. These experiences can help the small- and medium-sized towns keep up with global competition and cancel migration and erosion of intellectual potential.

Opis: The European economic model benefits from market forces as conditions for achieving goals of enterprises and consumers and economic efficiency is assured by necessary market infrastructure. Competition authorities are, without a doubt, one of the crucial pillars of the (social) market economy. The strength and impact of the competition rules is determined by their efficient implementation. The modest results to date of the competition policy in transitional economies militates in favor of an increase of the institutional capacity and require strengthening of the regulatory powers of public agencies in construction of an efficient economic system. Establishing a system of competitive markets through sectoral regulation, competition protection and state aid control at the national level requires a valid solution for a variety of legal, political and institutional conflicts. As the experience of the countries of South-East Europe has shown, many difficulties arising from the establishment of a functioning control system are procedural and relate to institutional building dilemmas. The purpose of this article is to shed light on the requirements the Republic of Serbia has to satisfy in accession negotiations, and in particular, those related to building an efficient system of state aid control.

Opis: Efficient regulatory mechanisms that induce innovation, co-operation and deter competition law infringements have recently been the subject of growing attention. Competition is essential to the innovation process which in general terms enables entrepreneurship. But so too is co-operation between firms which requires an exchange of information and may lead to inefficient collusive behaviour. The optimal trade-off between the provision of stable entrepreneurial incentives and the new European competition law’s reform with the self-assessment system has been largely missing from the current scholarly debate. This paper identifies the unintended, harmful horizontal side effects of this new European self-assessment system upon the entrepreneurial activity, offers a legal evaluation of the optimal entrepreneurial incentive mechanisms and provides legal and entrepreneurial arguments for an improved regulatory response.

Opis: We use an institutional approach to analyze differences and similarities between competition policy regimes in Slovenia and Germany. We first indicate differences that exist in the implementation of EU competition law at the national level, given the unified framework of EU competition policy. In a next step, we discuss recent cases in both countries and indicate how historical developments and economic factors influence decision making and case law. We also discuss recent developments of the national competition policy regimes and indicate how the digital economy might shape competition policy in the future.
