Megjegyzések:aBusiness groups have been described as improving the value of the affiliated firms they control, which is often beyond the capability of standalone firms. The purpose of the current study is to analyze the financial performance of affiliates of diversified Pakistani business groups relative to standalone firms. The current study employs data from 284 Pakistani listed non-financial firms from 2008?2015. In order to test the hypotheses, two dependent variables are used, namely, accounting (Return on Assets (ROA)) and stock market (Tobin's Q) measures of performance. Specifically, this study probes and compares the performance measures of group member and standalone firms. The findings of the study suggest that business group memberships have statistically significant effects on accounting and stock market measures of firm performance. In addition, size and sales growth have an increasing effect on the performance of firms. We believe that business groups in Pakistan are efficient economic actors and can be considered responses to high transaction costs and market failures.

Cím:The Significance of Forests and Algae in CO2 Balance : a Hungarian Case Study / Attila Bai, József Popp, Károly Pető, Irén Szőke, Mónika Harangi-Rákos, Zoltán Gabnai
Dátum:2017
ISSN:2071-1050
Megjegyzések:This study presents the sequestration and emissions of forests and algae related to CO2 while providing a comparison to other biomass sources (arable crops, short rotation coppices). The goal of the paper is to analyze the impact of the current CO2 balance of forests and the future prospects for algae. Our calculations are based on data, not only from the literature but, in the case of algae, from our own previous experimental work. It was concluded that the CO2 sequestration and natural gas saving of forests is typically 3.78 times higher than the emissions resulting from the production technology and from the burning process. The economic and environmental protection-related efficiency operate in opposite directions. The CO2 sequestration ability of algae can primarily be utilized when connected to power plants. The optimal solution could be algae production integrated with biogas power plants, since plant sizes are smaller and algae may play a role, not only in the elimination of CO2 emissions and the utilization of heat but also in wastewater purification.

Cím:Role of domestic financial reforms and internationalization of non-financial transnational firms : evidence from the Chinese market / Muhammad Saad Baloch, Abubakr Saeed, Ishtiaq Ahmed, Judit Oláh, József Popp, Domicián Máté
Dátum:2018
ISSN:2071-1050
Megjegyzések:The successful internationalization process of Chinese firms which enhances the sustainability of the Chinese economy receives massive research attention. Studies emphasize that firm's motives and institutional voids play a pivotal role in getting benefits from the internationalization process, but the factors that initiated this process have been overlooked. The objective of this study is to explore the impact of those institutional factors which initiated the internationalization process. This study reveals that institutional factors of cross listing and increased financial availability induced the internationalization process of Chinese firms. Using the financial data of non-financial firms for the period of 2005-2015, we demonstrate that the domestic financial reforms initiated the internationalization process that helps Chinese economies to achieve sustainable economic development. The study also finds that state-ownership helped firms to gain more from increased financial availability than the stand-alone firms. The study concludes that the open business environment helped firms to survive and sustain the international pressure successfully and maintain their sustainable performance.

Cím:The Challenge of Feeding the World / Fróna Dániel, Szenderák János, Harangi-Rákos Mónika
Dátum:2019
ISSN:2071-1050
Megjegyzések:The aim of the present research is to provide a comprehensive review about the current challenges related to food security and hidden hunger. Issues are presented according to major factors, such as growing population, changing dietary habits, water efficiency, climate change and volatile food prices. These factors were compiled from reports of major international organizations and from relevant scientific articles on the subject. Collecting the results and presenting them in an accessible manner may provide new insight for interested parties. Accessibility of data is extremely important, since food security and its drivers form a closely interconnected but extremely complex network, which requires coordinated problem solving to resolve issues. According to the results, the demand for growing agricultural products has been partly met by increasing cultivated land in recent decades. At the same time, there is serious competition for existing agricultural areas, which further limits the extension of agricultural land in addition to the natural constraints of land availability. Agricultural production needs to expand faster than population growth without further damage to the environment. The driving force behind development is sustainable intensive farming, which means the more effective utilization of agricultural land and water resources. Current global trends in food consumption are unsustainable, analyzed in terms of either public health, environmental impacts or socio-economic costs. The growing population should strive for sustainable food consumption, as social, environmental and health impacts are very important in this respect as well. To this end, the benefits of consuming foods that are less harmful to the environment during production are also to be emphasized in the scope of consumption policy and education related to nutrition as opposed to other food types, the production of which causes a major demand for raw materials.

Cím:Constraining Factors in Hungarian Carp Farming : an Econometric Perspective / Gyalog Gergő, Oláh Judit, Békefi Emese, Lukácsik Mónika, Popp József
Dátum:2017
ISSN:2071-1050
Megjegyzések:Although carp farming had a key role in the Blue Revolution at a global level, European carp aquaculture has stagnated over the past 25 years without achieving any productivity gains. The objective of this study was to identify the factors and mechanisms constraining production and productivity growth in pond-based carp farming in Hungary, as the country is a good representative of the EU pond-based farming sector. By using data from 44 carp farms, different specifications of the Cobb-Douglas production function were parameterized to investigate the determinants of yields and to assess the extent of economies of scale. Descriptive statistics show that large differences exist in productivity between individual farms, meaning that it is hard to implement technical standards and to ensure repeatability in extensive carp farming technology. Econometric analysis demonstrates that economies of scale do not prevail in pond-based farming in Hungary, so a concentration of farms would not stimulate a growth in carp farming. This may explain the stagnation of carp aquaculture, as the only European aquaculture segments which can grow are those that can exploit economies of scale. Further analysis demonstrates that labour is an important factor of production, and a decreasing workforce may constrain the intensification process of production. On the other hand, mechanisation did not prove to be a significant contributing factor to yields, indicating that large investment in equipment has a limited role in carp farming.

Cím:Sustainable public transportation in a Volatile, Uncertain, Complex, and Ambiguous (VUCA) age / Tünde Zita Kovács, András Nábrádi, Szabolcs Tóth, László Huzsvai, Adrián Nagy, Beáta Bittner
Dátum:2023
ISSN:2071-1050
Megjegyzések:A well-functioning public transport system is one of the foundations of the Smart city concept and sustainable cities. The COVID period offers an excellent opportunity to examine the impact of different factors, because throughout this period society was faced with both health and governmental impacts that had different effects. Public transport use in the EU member states from the turn of the millennium until the beginning of the pandemic ranged from 17-18% to 27% of total journeys. The COVID-19 virus caused a 5-7% decrease in public transport use. The present study analyses the relationship between these effects and the number of paying passengers on public transport in Debrecen. Four hypotheses were put forward, i.e., that (1) the evolution of travel tickets, (2) general passes, (3) discounted passes and (4) replacement tickets were influenced by the evolution of the active COVID-19 case rate. The data were collected from the Debrecen Transport Company (DKV) for the period 1 January 2020-12 December 2021, and the Worldometers.info database. Statistical analyses were performed using an autoregressive and moving average (ARMA) model. We found that COVID`s active case numbers did not affect sales, but some of the government measures did have an effect. The results of this research can be used to inform future decisions to maintain and improve urban transport.

Cím:A Bibliometric Analysis of Sustainable Food Consumption: Historical Evolution, Dominant Topics and Trends / Kristia, Kristia; Kovács, Sándor; Bács, Zoltán; Rabbi, Mohammad Fazle
Dátum:2023
ISSN:2071-1050
Megjegyzések:The major goal of this study is to trace the emergence of SFC-related research across time, using a thematic map and a list of corresponding publications. In addition, this study aims to determine the author who has made the most significant contribution to this particular field. This study provides a comprehensive bibliometric analysis of the historical development and current trends in sustainable food consumption research, examining 2265 articles published between 1990 and 2023. Using the bibliometrics package of R Studio software version 4.2.1 and its Biblioshiny package, articles from the Scopus and Web of Science databases are examined. In the field of sustainable food consumption, we identify five distinct research phases: initial stagnation, infant growth, post-economic crisis, expanding phase and COVID-19 and post-pandemic. While research on broader sustainability topics can be traced back to the early 20th century, a very limited number of articles on sustainable food consumption was published in the 1990s. However, the number of publications increased incrementally over time, with a notable uptick in interest around 2015, and the subject was still being discussed in 2022. The emergence of the COVID-19 pandemic marked the beginning of the most recent phase of research, which analyzed the consumption patterns of consumers before and after the pandemic. Our study highlights key authors, documents and sources related to sustainable food consumption. The United States, Italy and the United Kingdom emerged as the most active contributors to the research on sustainable food consumption and were additionally the countries with the largest global market shares for organic products. Major sub-themes including organic food, food waste, sustainable development and food security, together with consumer behavior and organic products appeared as being the most researched sub-themes of recent times. The results of this study suggest that more research is related to sustainable food consumption in countries with a low organic food market share. In addition, the investigation of actual data on food waste, carbon footprints and greenhouse gas emissions resulting from food production and consumption is essential to gain holistic insights.

Cím:Building Coalitions for a Diversified and Sustainable Tourism : two Case Studies from Hungary / Lakner Zoltán, Kiss Anna, Merlet Ivan, Oláh Judit, Máté Domicián, Grabara Janusz, Popp József
Dátum:2018
ISSN:2071-1050
Megjegyzések:The development of the tourism sector has been a question of strategic importance for Hungary, a small, open economy with limited natural resources. At the same time, these efforts often generate considerable environmental conflicts, decreasing the sustainability of the environment. To understand the potential methods of sustainable tourism development, and to develop the optimal policy, it is essential to clarify the actors, their systems of interest and the potential ways of forging coalitions between them. The article presents an analysis of two case studies of rural tourism development: the "softening" of tourism at the most important touristic attraction in Hungary, Lake Balaton; and the conflicts arising from wine tourism development. Based on institutional economics, principle?agent theory and strategic management, and applying the MACTOR method, the authors identify the key actors, present the network of their mutual influences and goals, determine the most important conflicts and highlight the potential coalitions between them from the point of view of sustainable rural tourism development, as well as ways to further develop the regulatory environment. Based on this analysis, the article proves: (1) the importance of the modernization and re-organization of the public administration structure, focusing on optimal utilization of resources, as opposed to attaching to traditions; (2) the importance of forming clusters of different partners; (3) the strengthening of the knowledge base of decisions concerning sustainable tourism management; and (4) increasing conscious planning, based on the inclusion of different interest groups and long-term prognoses in local decision making, minimises the environmental burden of tourism.
