Material flows and stocks of a service company from Debrecen
313-321Views:450Over the past 25 years, many renowned scientists from a number of research institutes have developed a new research method, a new family of methodologies which is the MFA (Material Flow Analysis). The importance of MFA is given by the extent of excited material flows created by mankind. The basis of MFA's growing success is a radically new, interdisciplinary vision that requires collaboration between the natural and social sciences (ecology, thermodynamics, and economics), not only as an effective tool for examining material efficiency of production and environmental pressures, as well as the security of supply of the strategic material requirements of the system under investigation. In our article, we conduct an enterprise level analysis of the input and output side material flows and materials of a service company in Debrecen for 2018 using the MFA method. MFA indicators capture environmental pressures in a natural dimension, that is, in terms of mass, energy, or land, respectively, in terms of kilograms or tons, of the company's raw materials and their changes, or material inputs.

Examination of International Fisheries’ Agreements with Game Theoretic Approaches
167-175Views:291Nowadays, the application of game theoretic approaches is becoming more and more popular in different types of resource management problems. Overfishing is a growing problem worldwide and well known from literature. Unfortunately the tragedy of commons could be observed in several empirical studies in the case of international fisheries. In our paper, we focus on the examination of international agreements related the fisheries’ management (with special focus on the issues of overfishing) using game theoretic approaches. We review the history of fisheries’ agreements and the main game theoretic results, well known from literature. We highlight the main types of games applied in the previous research studies and summarize the main results related to the outcome and the stability of the game. To this topic better understood, certain empirical examples are introduced as well.

A Possible Way to Encourage Sustainable Consumption
21-40Views:495With the growth and spread of the concept of sustainable consumption and with the re-emergence of issues related to needs, the basic concepts of consumption need to be analyzed from aspects not inspected by mainstream economics. Consumer behaviour is largely determined by the prevailing values of society and nowadays consumption symbolizes social status. The purpose of this study is to critically examine the concept of utility, to review traditional and alternative concepts and aspirations related to the promotion of sustainable consumption. The authors argue, that utility can not only be examined by narrow economic considerations; the values of present and future generations also must be taken into account when determining what is considered to be useful. The study concludes by presenting alternative financial solutions that encourage sustainable consumption. The presented examples demonstrate, that complementary currency models are suitable means to encourage sustainable consumer behaviour. These are external motivational tools eliciting the desired behaviour through reward schemes.
