Human rationality, environmental challenges and evolutionary game theory
15-19Views:309In recent years, game theory is more often applied to analyse several sustainable development issues such as climate change and biological diversity, but the explanations generally remain within a non-cooperative setting. In this paper, after reviewing important studies in this field, I will show that these methods and the assumptions upon which these explanations rest lack both descriptive accuracy and analytical power. I also argue that the problem may be better investigated within a framework of the evolutionary game theory that focuses more on the dynamics of strategy change influenced by the effect of the frequency of various competing strategies. Building on this approach, the paper demonstrates that evolutionary games can better reflect the complexity of sustainable development issues. It presents models of human – nature and human – human conflicts represented by two-player and multi-player games (with a very large population of competitors). The benefit in these games played several times (continuously) will be the ability of the human race to survive. Finally, the paper attempts to identify and classify the main problems of sustainable development on which the game theory could be applied and demonstrates that this powerful analytical tool has many further possibilities for analysing global ecological issues.

BRAIN DRAIN AND ITS REPERCUSSIONS ON THE NEEDS OF THE PALESTINIAN LABOR MARKET: A STUDY OF THE CAUSES AND CONSEQUENCES OF MIGRATION AMONG EDUCATED YOUTH
Views:332This study examines the consequences of the outflow of young people from the occupied territories for the Palestinian labor market. This phenomenon is labeled a "drain" because it deprives the area of many educated individuals needed for its development. Commonly discussed as a political issue and as a consequence of war, the problem is often not addressed as an economic issue. Moreover, emigration exacerbates the population problem as young females and males leave the area for neighboring states and seek permanent sanctuary in them. When this group is not present to aid in the process of internal development, the investment in their education is lost.
In all areas of the world, one may observe graduations from universities and other institutions leading to the majority of proficient students leaving or attempting to leave to assume responsible positions. This exodus constitutes a serious problem for the donor country in the sense of its youth development, and a serious problem for the recipient country deprived of the services of these skilled graduates. The total "drain" of the talented becomes an important economic problem. The outflow of trained individuals is not unique to Palestine; therefore, similar serious situations are prevalent in many developing countries, particularly those situated in proximity to concentrations of wealth. The magnitude of the Palestinian outflow, however, has not previously been demonstrated. The analysis of Palestine's probable situation was accepted reluctantly, as many information sources refused or were too cautious to share statistics related to this study. The specific objective of the analysis is to present these and related statistics. The concern in this paper is with the consequences of the phenomenon and the associated costs in disutility. There are other consequences and costs, all of which are important.

ANALYSIS OF CONSUMER BEHAVIOUR IN THE EUROPEAN POULTRY MEAT MARKET
Views:948This research has also confirmed that poultry meat is currently in its golden age, not only in our country but also globally. The beneficial physiological effects of poultry meat, its nutritional value (high protein content), and its role in modern nutrition and diets have made it the most popular and 'fashionable' meat product of our time. Healthiness as a megatrend has favoured the consumption of poultry meat, which has been consumed for decades, and is reflected in the growth in production, trade and consumption. The trend of environmental awareness has also pushed the meat market towards the consumption of poultry meat as it is one of the least environmentally intensive compared to other meat types. Poultry meat is the second most commonly consumed meat in the EU, but in some European countries, it has taken over the overall lead (e.g. Hungary, Cyprus, and the UK). Poultry is not only preferred for its healthiness and low environmental impact, it is also an easy, versatile, quick-to-prepare, cheap source of protein. These advantages are expected to lead to further growth in the future in terms of production, trade and consumption, China, the US, the EU and Brazil dominate the poultry sector.

Board diversity and firm value; mediating effect of CSR of listed oil firms in Nigeria
Views:478In this empirical study, the mediating effect of corporate social responsibility (CSR) on the nexus between corporate value and board diversity is investigated. However, hypotheses developed for this study were tested with annualized panel dataset of eight (8) Nigerian listed oil and gas firms in the upstream sector spanning 2012 to 2019. Stakeholder theory was used to underpin the study. The study employed three indicators for board diversity (board professionalism, board nationality and board gender), Tobin’s Q and amount spent on CSR. The panel regression results show that looking at the indirect effect in Model One; board diversity has no significant effect on firm value. However, empirical findings indicated that CSR exerts a significant and positive relationship with corporate value. Considering Model Two, the results show that CSR plays a pertinent role in establishing the nexus between corporate value and board diversity, this finding is congruent with stakeholder theory. The study recommends that environmental sensitive firms should maintain an appropriate and balance diverse board as it plays a pertinent and significant role in establishing the nexus between stakeholder relationship and the firms, which can also serve as a mechanism to mitigate manager's opportunistic tendencies behind CSR investment.

Profitability of cassava production in the Ashanti region of Ghana
66-69Views:1063Cassava is a crop that is massively produced and consumed in Ghana even though it is produced by subsistence farmers. The aim of this study is to analyse the cost and returns of cassava farmers. Farmers profitability was accessed using the gross margin, net present value and the benefit cost ratio. SWOT analysis was conducted to access challenges faced by cassava farmers. Data was collected by personal interview from fifty (50) cassava growing farmers in the Sekyere East District of the Ashanti Region, Ghana. The Costs and returns analysis show gross margin of USD 22.75 per acre. It was concluded that cassava is cultivated for both consumption and revenue. Even though there is low investment of capital in cassava production, it helps farmers to make use of available resources (personal savings, land and labour) which would have been idle. Further should compare profitability of crops that compete for use of famers land.

Strategic approach to sustainable business of Galenika Fitofarmacija A.D. in a context of accession of Republic of Serbia
109-110Views:251Strategic management is ultimately concerned with the quest for sustainable advantage. To be practical, advantage for commercial firms concerns earnings and sustainable means a concern with earnings into the future. Pearce and Robinson define strategic management as a set of decisions and actions that results in the formulation and implementation of plans designed to achieve a company’s objectives. David says that strategic management can be defined as the art and science of formulating, implementing, and evaluating cross-functional decisions that enable an organization to achieve its objectives. Strategy is also hierarchical concept – it takes place at three different levels: corporate, business, and functional. These levels correspond with the activities of managers in different parts of the organization.

The operation of the Hungarian broiler product chain
47-50Views:339The general objective of this paper is to present the inner connections of the broiler product chain and the process of value generation in the economic situation of 2007. I introduce the input-output model of the broiler product chain adapted from macro-economic analysis, in which I calculated the direct connections of the product chain phases and between the national economic branches outside the chain. Then I point to the disproportion of the product chain through the profit distribution. Moreover, to evaluate the process of the value generation I demonstrate the value added generated along the value chain (year 2007). On the basis of the results 825 EUR of value added is realized to one ton of ready product (chicken meat), from which the major portion is shared by processing. The paper also determines the added value and the major factors influencing its ratio within the product chain.

Futsal for the blind: a new opportunity for Hungarian people with visual impairments to get engaged in physical activity
37-41Views:379The proportion of Hungarian citizens involved in regular physical activity is extremely low and rates are even lower amongst people with disabilities. It is, however, undoubtedly easier to stimulate physical activity if a wide variety of different sports is accessible for them. Blind futsal was introduced by an NGO, Sports and Leisure Association for the Visually Impaired and it has been played in Hungary for only a year.
The present work, by introducing this special sport through document analysis and semi-structured interviews, aims at calling sport professionals’ attention to the unexploited opportunities of adapting sports to blind people’s special needs. The author also wishes to highlight the power of a civil initiative and the inmense effort people with visual impairments themselves make for improving their own sporting opportunities. -
Reporting companies’ performance – in respect of the international financial reporting standards (IFRS)
107-112Views:360The role of information became more important due to rapidly changing technical conditions, market and economic regulations in our globalizing world. Several regulations tend to provide the framework for reporting performance and income of the companies, but in different statements performance is inconsistently presented and many kind of evaluation method exist in the practice. These facts led to the demand of properly assess the financial health of an organization, and created a commonly accepted rule-system, which name was International Financial Reporting Standards (IFRS). In this paper I tend to present the statements, definitions and factors, which can have great influence in representing the performance, income of the company in the frame of the IFRS, and reveal the differences between the other accounting regulations (EU directives, Hungarian Accounting Act) in this field.

Allocation of structural funds before and after the brexit: An exercise in the economics of cake-sharing
69-71Views:415What impact has the Brexit on the allocation of money from the structural funds? As the UK is a net contributor to the EU budget, the budget for Structural and Cohesion Policy will shrink. This will have an impact on the allocations of the structural funds to the remaining members of the EU. In order to estimate the allocation of the structural funds to the remaining EU members an allocation model is developed in this article. It appears that the model results do not only show the sharing of the cake, but also the size of it.

Structural Breaks or Continuous Adjustments in Grain Production and Prices 1961-2014? An Explorative Study
11-22Views:323This article analyses grain production and prices 1961-2014. We first describe the development in aggregated and relative allocation of land worldwide for wheat, corn and soybeans, and the growth in production volumes and yields. We then proceed by analyzing long-term price relationships. Finding that grain prices are strongly co-integrated, we estimate an Error Correction Model to see whether deviations from the long-run equilibrium are quickly adjusted. Furthermore, we investigate whether changes in land allocations for these principal field crops are best described as a continuous process or as a series of structural breaks, hypothesizing that events like the introduction of GM technologies and the “energizing” of corn after 2005 caused structural breaks in acreage shares and relative prices. Given the major and sometimes dramatic political events and technological changes during this period,one would expect to find significant structural breaks in grain production, yields and prices. However, our main conclusion is that grain markets generally adjust smoothly and continuously. Prices adjust quickly towards long-run equilibrium, and the results from a series of Chow tests indicate that the changes in relative land allocations have progressed as a relatively smooth process with few structural breaks.

SOCIOECONOMIC DETERMINANTS OF THE INTENSITY OF MUSHROOM COMMERCIALISATION IN GREATER ACCRA REGION, GHANA
Views:408Fungi, such as mushrooms, have the unique ability to decompose and convert obstinate organic substances into protein, thereby improving nutrition, increasing food security, fostering sustainable agricultural production, and generating income for farmers. Since the 1990s, the Ghanaian government, through the Mushroom Unit of the Food Research Institute of Ghana, has promoted the cultivation and commercialization of (oyster) mushrooms in Ghana as an additional source of income for the urban poor. This study used a cross-sectional survey design, questionnaires, and validated structured interview schedule instruments to collect data from 153 mushroom farmers in the Ga East and Adentan Municipalities of the Greater Accra Region to determine the intensity, degree, characterisation, and factors that influence the intensity of oyster mushroom. The Crop Commercialization Index, frequency, mean, standard deviation, Two Stage Least Square regression and Ordinary Least Square regression were used to analyze the data. The results showed a low intensity (GHC 10202.20) but a high degree (75%)of oyster mushroom commercialization in the study area. The vast majority of oyster mushroom farmers (95%) were highly commercialized, selling more than half of their oyster mushroom output. Except for age, farmers' level of formal education, land ownership, and production volume of oyster mushroom all positively influenced the intensity of oyster mushroom commercialization. The Food Research Institute, the Ministry of Food and Agriculture, and development organizations should step up efforts to increase oyster mushroom production and attract educated, young, and unemployed people to oyster mushroom ventures.

Luxury wine: analyzing motivations of luxury wine buyers in the US market
51-58Views:559The purpose of this research study was to describe motivations and demographics of luxury wine buyers in the US market. An online survey was completed by 1081 US wine consumers, of which 473 were designated to be luxury buyers based on price spent on wine. Standard demographic and wine consumer scales were utilized for profiling. Results show that the luxury wine buyer is more likely to be male, aged 30 to 50, with a higher income and education level. Motivations of the luxury wine buyer are different than the non-luxury wine buyer, and reasons for purchasing luxury wine go beyond mere collecting. This research is one of the first to analyze the luxury wine consumer in the US market, and provides useful information for wine marketers and researchers on the profile of the luxury wine buyer in America.

Some aspects of accounting and management accounting during economic downturns
33-35Views:360Economic slowdown and downturn creates new situation for every organisation, no one can avoid facing to new situation created by the global financial-, and economic crisis.All of the organisational function should reconsider its own role within the company due to the new circumstances, Accounting and Mangement Accounting can not be exception, but they have more complex and emphasized role in these difficult times. In the following paper I can not avoid to mention some general statement about importance of accounting and accounting principles, while there are a number of criticalaccounting and financial reporting issues that accountants and auditors should consider.In the framework of the paper I can not face with all relevant issues of the topic, but after some general statement I would like to highlight some special area regarding to management accounting, which can be more important during these challenging time for decision makers and accountants.Regarding to balance sheet analysis its important to mention current debate about fair value comparing with historical cost from accounting point of view, on the other hand from the view of management reporting system I would like to highlight the importance of working-capital indicators. More practical topic is the crucial role of budgeting and forecasting during economic downturns, and at the end I would like to show why it is more important monitoring price variance and indirect cost allocation in these uncertain business circumstances.

Sustainable initiatives in marginal rural areas of Serbia: A case study of dimitrovgrad municipality
7-13Views:246This paper is based on a 2009 case study research on the role and impacts of rural initiatives in Dimitrovgrad, South-eastern Serbia region. This area is of interest, because of local efforts to conserve autochthonous livestock breeds, and the work of small holders and independent professionals involved farming and rural tourism activities. The research used participant visits to initiative places, drawing on farm visits, meetings with stakeholders and analysis of secondary information. The study highlights that local organizations are running without link to initiatives.Although, Serbia country has well structured rural developments programs, those still are harmonising.Thus, throughActor-Network approach is suggested which turn around a farm manager. This may represent to all stakeholders within itiatives (on-farm and non-farm). Besides, local food products issues from initiatives may reconnect providers and consumers, revaluing local food products. However, is necessary the institutional and organizational involvement to encourage the initiatives. Furthermore, to promote touristic places, by an integrated rural tourism approach it may involve all stakeholders to promote local products and issues from initiatives. Indirectly it may create local employs.

Sensitivity of technical efficiency estimates to estimation methods: an empirical comparison of parametric and non-parametric approaches
67-72Views:302This paper highlights the sensitivity of technical efficiency estimates to estimation approaches using empirical data. Firm specific technical efficiency and mean technical efficiency are estimated using the non parametric Data Envelope Analysis (DEA) and the parametric Corrected Ordinary Least Squares (COLS) and Stochastic Frontier Analysis (SFA) approaches. Mean technical efficiency is found to be sensitive to the choice of estimation technique. Analysis of variance and Tukey’s test suggests significant differences in means between efficiency scores from different methods. In general the DEA and SFA frontiers resulted in higher mean technical efficiency estimates than the COLS production frontier. The efficiency estimates of the DEA have the smallest variability when compared with the SFA and COLS. There exists a strong positive correlation between the efficiency estimates based on the three methods.

Quality-satisfaction-loyalty: consumer behaviour in catering
5-11Views:436Our study is the result of the initial research of a qualitative and quantitative research consisting of more stages. The survey was made between 2007 and 2013 and specially focused on the satisfaction of Hungarian customers of catering enterprises with hot kitchen as well as on factors influencing satisfaction and customer loyalty. The results proved that a well planned, central strategy cannot be prepared for the whole catering industry as even enterprises with the same profile (warm food kitchen) show significant differences. The most important task for an enterprise is to establish and know its appropriate clientele well in order to suit its services, selection to their requirements. Our assumption that customers of fast food restaurants, canteens have lower expectations from selection, personal relations, quality of services than customers of restaurants, public houses, wayside inns, brasseries with traditional methods of selling was proven. In the lattest, the main aspect of choosing a 'favourite place' was the quality of human relations, with the special role, besides other customers, of the staff. Establishing unique atmosphere to the liking of customers can be regarded as an important point of the operational strategy. It was also proven that the majority of regular customers of restaurants are men, coming from the economically active population. Other active users are youngsters, they mainly go to fast food restaurants. More impersonal advertisements hardly have any effect, while successful word of mouth propaganda can be achieved by consequent, high level work. Regular customers can be characterized by rather emotional than market-based attachment. Favourite units are mainly preferred because of their atmosphere, relationships with acquaintances and friends, not because of measurable features, selection or prices. Those visiting catering enterprises with hot kitchen more frequently are more critical and less satisfied, in spite of this, they are reluctant to part from their regular places.

Greener cement sector and potential climate strategy development between 2015-2030 (Hungarian case study)
65-74Views:549Advancing the domestic industrial production towards a sustainable, resource-preserving direction can become an important pillar to support competitiveness in the European Union, as well as in Hungary. Reaching the de-carbonization goals for industrial production via lowering the production volume may result in less desirable macro-economic effects, so decisions which concern the industry require a lot of attention from the climate policy as well. In the case of the cement sector, economic actors have to be motivated to make energy-efficiency investments and technology developments, which also show promise in terms of business efficiency. In the more natural-resource-intensive branches of the industry, both innovations and technological developments will be required to reduce the amount of used non-renewable energy resources, keep it in the industrial cycle, and reduce environmental load. The importance of greener cement will be essential in the near future to reduce the sector’s CO2 emission levels. We need to identify more sector branches which relate to sustainability, which can aid the country in establishing long-term competitiveness that points towards the de-carbonization goals. The cost-efficiency aspects of this development process are the most tedious questions in today’s business planning.

The effects of health tourism investments in tourism businesses in the Northern Hungarian Region
45-50Views:347In my article I woud like to find answers for the question how frequently and effectively the region’s business leaders in Northern Hungary participated in various development programs, as regards investments in health tourism, what developments have been made mainly in the area, what the positive effects of these developments were in the life of businesses, whether the businesses (leaders) feel successful, and how their success was manifested. I carried out a questionnaire survey among enterprises. From the data I calculated mean, SD and spectrum and examined the crosstab correlations as well, and the Cramer’s V associate coefficient and Contingency coefficient. The results of the correlation tests could be summarised as the following: According to the survey, the number of the medium-sized enterprises being involved utilised a significant proportion of their development funds, compared to the micro and small enterprises. Although the idea of spas winterizing their pools was not considered an important development, both the adventure and wellness elements were important for the construction of thermal baths. In the case of hotels, the expansion of wellness elements and other additional services together with the development of marketing activities played an important role. Besides the positive business publicity, enterprises see the positive effects of the investment in the increase of their income; the success can be the result of the adequate supply of components, the professional management and that of positive image.

POTENTIAL USES OF BLOCKCHAINS IN HUMAN RESOURCES
Views:290Blockchain technology offers businesses many opportunities for more efficient operation and safer data management. It also becomes easy tostore and share employee data, while the blockchain guarantees that it does not fall into unauthorized hands. The management of financial transactions and the automation of the payment process are also a great advantage for businesses, which can manage the payment of wages andbenefits more efficiently. Another area of application of blockchain technology is the creation of more efficient workflows that can improve productivity and reduce costs. The management of work schedules and optimized work processes will also be easier with the help of the blockchain, so businesses can become more efficient and effective. In this article, the relationship between HR and blockchains was explored through a meta-analysis based on available related publications. -
Economic importance of the Hungarian sports sector in international comparison
109-114Views:516Sport is one of the most dynamically developing sectors in the world. During my research, I was looking for the answer to why and how the economic aspects of sport have evolved in recent times. I examined and evaluated sports economy indicators for the global (The European Union) and territorial (Hungary) units (for the last twenty years). The need for measurability is constantly increasing nowadays. This can also be seen in the markets of the sports sector, so we can find databases that are increasingly expanding in this sector. I have analysed EUROSTAT databases - with indexing – which can provide relevant information. The research field was two economic aspects, the number of employee and trade in sporting goods. The number of employees was analysed separately by the European Union and Hungary. In the examination of trade in sporting goods The Hungarian trade in sporting goods was compared to the neighbouring European Union countries. Based on my results, I can say that the economic importance of the sports sector has increased within the European Union and Hungary as well because the number of employed people in sports and the trade in sporting goods has increased.

Correction method on fairs’ attraction radius
37-41Views:341At auditing a fair the measure and evaluation of the exhibitors’ distance is a important task and can be used for further promotion of the fair. In analyzing the attraction radius of different fairs one can discover some figures that may raise questions regarding a simple averaging of the attraction distances. According to the research of the author, the bias in the attraction radius can be caused by to factors: the size of the attraction region and the distance from the region’s business center. Authors explored the bias factors and suggest a correction method to remedy it. A theoretical correction model was applied to evaluate three agribusiness fairs. It is established that the corrected attraction radius gives more realistic result than the simple averaging of exhibitors’ distance.

Agricultural cooperatives and their membership in cooperative unions in Serbia
25-32Views:377Goal of this paper is to analyse business of agricultural cooperatives in Serbia and their territorial distribution. Paper also comprehends analyses of premises of directors of agricultural cooperatives towards cooperative associations, based on result of survey conducted on chosen sample. Analysis is based on the hypothesis that reform processes present in the Serbian economy, and completely absent from cooperative sector, have weaken the work of cooperative unions and undermined regular relations between cooperatives and their associations. Paper also analyse premises of directors of agricultural cooperatives on relevant questions on membership and work of 12 regional, provincial and Cooperative union of Serbia, based on result of survey conducted in 148 or 7.2% of 2.055 agricultural cooperatives in Serbia. For cooperatives that are not members of any union, paper gives systematization of reasons why cooperative is not member and motives that could inspire cooperative to become a member. For cooperatives that are members of some union, we give analyses of answers if cooperative is satisfied with work and activities of union conducted for cooperative welfare; and suggestions for activities that cooperative unions should practice in the interests and needs of their members.
