Cím:Does Business Group Affiliation Matter for Superior Performance? Evidence from Pakistan / Ishtiaq Ahmad, Judit Oláh, József Popp, Domicián Máté
Dátum:2019
Megjegyzések:Business 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:Financial Inclusion, Technological Innovations, and Environmental Quality: Analyzing the Role of Green Openness / Mahmood Ahmad, Zahoor Ahmed, Yang Bai, Guitao Qiao, József Popp, Judit Oláh
Dátum:2022
ISSN:2296-665X
Megjegyzések:Undoubtedly, financial inclusion (FIN) contributes to economic development by enabling individuals and businesses, particularly small and medium enterprises, to access financial services. Financial inclusion may also have environmental implications; however, limited studies have looked into the nexus between financial inclusion and environmental quality. Also, the possible impacts of technological innovation and green openness remain unexplored in this nexus. In this context, this article probes the relationship between financial inclusion, technological innovation, green openness, and CO2 emissions in BRICS countries while controlling for economic growth and energy consumption. Using the panel times series data from 2004 to 2018, this study uses advanced econometric techniques for empirical analysis robust to cross-sectional dependency and slope heterogeneity. The empirical results unveiled that FIN contributes to environmental degradation in BRICS countries. In contrast, technological innovation and green openness pose mitigating effects on emissions, thus promoting environmental sustainability. Environmental degradation is evidenced to enhance due to rising economic growth and energy utilization. Financial inclusion, technological innovation, and green openness Granger cause CO2 emissions, but not the other way around. Further, technological innovation, green openness, and financial inclusion Granger cause each other. Based on the empirical results, this study recommends that BRICS countries should promote technologicalinnovation, green openness, and at the same time, integrate financial inclusion with environmental policies to achieve climate-related goals.

Cím:Energy efficiency in transportation along with the belt and road countries / Usman Akbar, József Popp, Hameed Khan, Muhammad Asif Khan, Judit Oláh
Dátum:2020
ISSN:1996-1073
Megjegyzések:China's huge investment in the "belt and road initiative" (BRI) may have helped improve the economic level of participating countries, but it may also be accompanied by a substantial increase in greenhouse gas (GHG) emissions. The BRI corridors aim to bring regional stability and prosperity. In such efforts, energy efficiency due to increased transport has been overlooked in the recent literature. This paper employed a data envelopment analysis of the slack-based measurement (SBM) for bad output to assess the transport energy efficiency of 19 countries under the BRI economic corridors. By using the most cited transport-related input variables, such as vehicles, labor, motor oil, jet fuel, and natural gas, this study first analyzes the transport energy efficiency by first assuming the output variables individually and then takes two years as a pre- and post-BRI case by considering the aggregated output model. The results show an increase in economic activity but a decline in transport energy efficiency in terms of consumption and emissions.

Cím:Impact of distributive justice on the trust climate among middle eastern employess / Ayman Alshaabani, Judit Oláh, József Popp, Samir Zaien
Dátum:2020
ISSN:2081-7452
Megjegyzések:Having a positive trust climate and organizational distributive justice is essential for any organization. Many studies have found that both trust and organizational justice have a direct positive impact on organizational performance. However, the relationship between them has not been considered widely, especially in the Middle East. Therefore, the study aims to examine the relationship between organizational distributive justice and the trust climate among the employees in three Middle Eastern countries and to find out what demographic variables affect this relationship. The sample of the study consisted of 190 employees who came from three countries, namely, Syria, Egypt, and Turkey. To achieve the purpose of the study, a questionnaire of 20 items was sent online to employees. . Later descriptive analysis methods and Pearson correlation were used to achieve the purposes of this study. The study found that there was a strong positive relationship between organizational distributive justice and the trust climate. Besides, there was a significant difference in organizational distributive justice when it was related to work experience. There were also statistically significant differences in trust in the supervisor, related to age; moreover, there were significant differences in trust in the organization and co-workers depending on work experience level, however, gender did not show any significant differences.

Cím:Smart Grid, Demand Response and Optimization: A Critical Review of Computational Methods / Ussama Assad, Muhammad Arshad Shehzad Hassan, Umar Farooq, Asif Kabir, Muhammad Zeeshan Khan, S. Sabahat H. Bukhari, Zain ul Abidin Jaffri, Judit Oláh, József Popp

Megjegyzések:In view of scarcity of traditional energy resources and environmental issues, renewable energy resources (RERs) are introduced to fulfill the electricity requirement of growing world. Moreover, the effective utilization of RERs to fulfill the varying electricity demands of customers can be achieved via demand response (DR). Furthermore, control techniques, decision variables and offered motivations are the ways to introduce DR into distribution network (DN). This categorization needs to be optimized to balance the supply and demand in DN. Therefore, intelligent algorithms are employed to achieve optimized DR. However, these algorithms are computationally restrained to handle the parametric load of uncertainty involved with RERs and power system. Henceforth, this paper focuses on the limitations of intelligent algorithms for DR. Furthermore, a comparative study of different intelligent algorithms for DR is discussed. Based on conclusions, quantum algorithms are recommended to optimize the computational burden for DR in future smartgrid.

Cím:Natural Resource Rent and Finance: The Moderation Role of Institutions / Muhammad Atif Khan, Muhammad Asif Khan, Kishwar Ali, József Popp, Judit Oláh
Dátum:2020
ISSN:2071-1050
Megjegyzések:This study empirically examines the nexuses between the natural resource rent and financial development in the context of the emerging economy of Pakistan, between 1984 and 2018, by subsuming the important role of institutional quality in this context under symmetric, asymmetric, and threshold settings. The literature to date provides no evidence on the asymmetric relationship between natural resource rent and financial development, and the moderation role of institutional quality in this connection. We show that natural resource rent negatively influences financial development, whereas institutional quality boosts financial development and positively moderates the relationship in the context of Pakistan. Also, we find a single significant threshold value of 3.097 above which the relationship of resource rent-finance turns nonlinear?as up to this threshold the coefficient is 3.228, which declines slightly to 2.804 above the threshold level. This implies that regulators should maintain at least an institutional quality level of up to 3.097 to experience the most desired financial benefits of the natural resource rent in Pakistan. Moreover, the results corroborate the existence of asymmetries in the relationship between the natural resource rent and financial development. This empirical evidence provides fresh insight for stakeholders regarding ambiguous natural resource rents and financial sector development nexuses and recommends that planning organs in Pakistan and other countries in a similar development cadre should use institutional quality as a tool to avoid the resource curse and view natural resources as a blessing rather than a curse.

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:Impact of Sleep Deprivation on Job Performance of Working Mothers : mediating Effect of Workplace Deviance / Yuwei Deng, Jacob Cherian, Kalpina Kumari, Sarminah Samad, Jawad Abbas, Muhammad Safdar Sial, József Popp, Judit Oláh
Dátum:2022
ISSN:1661-7827 1660-4601
Megjegyzések:The current study takes its philosophical roots from organizational behavior and psychology domains to investigate the impact of sleep deprivation on the job performance of mothers working in primary, secondary, and higher education institutions (HEIs) of Pakistan. It also examines the mediating role of workplace deviance in the relationship between sleep deprivation and the job performance of working mothers. The authors followed the non-probability convenience sampling technique to study the relationship between sleep deprivation, workplace deviance, and job performance. The structural analyses indicated that sleep deprivation has a significant negative impact on the job performance of working mothers and sleep-deprived individuals often tend to perform poorly at the workplace. Such workers are also more likely to engage in workplace deviant behaviors. Moreover, workplace deviance is also found to act as a mediating variable in the relationship between sleep deprivation and job performance. The present research bridges the literature gap on the rarely investigated factors, namely sleep deprivation and workplace deviance, and provide a detailed understanding of how these factors can influence the performance of working mothers, specifically in Pakistan.

Cím:The Misunderstanding of China's Investment, and a Clarification: "Faustian Bargain" or "Good Bargain"? On the OFDI Data of Central and Eastern Europe / Cheche Duan, Yicheng Zhou, Dehong Shen, Shengqiao Lin, Wei Gong, József Popp, Judit Oláh
Dátum:2021
ISSN:2071-1050
Megjegyzések:The close development of the economic relations between China and Central and Eastern Europe (CEE) since 2012 has triggered the European Union's criticism of China's foreign policy towards Eastern European countries. The European Union believes that China's investment growth has led to a governance crisis in CEE countries. Based on the global governance indicators of the World Bank and the outward foreign direct investment (OFDI) data of the Ministry of Commerce of China, this paper conducts a test using the panel data model and the r gression discontinuity method. An imbalanced panel dataset is adopted, covering 16 CEE countries from 2000 to 2018. The empirical research results indicate that, representing a small proportion of the investment inflows to CEE countries, China is not yet able to exert a domination effect on the region, and China's economic power is far less than the European Union's regulatory influence. Furthermore, China's share of the OFDI in CEE has a U-shaped effect on the regulatory quality of host countries, and the two have a mutually causal relationship. Specifically, the impact on the host country's regulatory quality is first manifested in the Shanghai effect, and when China's share reaches a certain level, it is manifested in the California effect. The U-shaped effect is associated with the strategic factors of CEE countries and China's positive contribution to good global governance.
