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:	Trade-Offs for the optimal energy efficiency of road transportation: Domestic cases in developing countries / Usman Akbar, Muhammad Asif Khan, Marryum Akmal, Éva Zsuzsanna Tóth Naárné, Judit Oláh
Dátum:	2020
ISSN:	1996-1073
Megjegyzések:	The increase in domestic transportation in developing countries may adversely affect the energy efficiency of road transportation due to effective productivity and carbon dioxide emissions (CO2). When evaluating quantitatively the countries on the efficiency frontier, poor efficiency can still be seen sometimes due to the slack available in undesirable output measures. This paper uses desirable and undesirable output variables, such as passenger-kilometers (PKM), tones-kilometers (TKM), and carbon dioxide (CO2), to compute the weakly efficient decision-making units (DMUs). The data envelopment analysis (DEA) technology is used to assess the efficiencies of the decision-making units (DMUs), which are countries in our case. Then, the trade-off method with efficient binding surfaces is used to attain the optimal efficiencies of the weakly efficient DMUs. The marginal rates aid this trade-off analysis. Resultantly, such marginal trade-offs do not deteriorate the efficiency of the DMUs below the frontier line. We calculate the maximum change (margin) in a specific variable amount when another variable`s amount is changed. Thus, such a computation gives us different margins, with which each output variable can be a traded off to bring a DMU further toward the closest optimal point possible. The marginal trade-off can help the managers and policymakers in effective decision-making, and it is further recommended to address efficiency damages (by the undesired outputs).

One of the goals of developing a transport corridor is to promote socio-economic development by improving connectivity and sustainable transport operations, which largely depends on the operational strategy. Trade-off policies can be important tools for gaining the competitive advantage of road transport corridors, and thus, help facilitate sustainable growth and welfare. This article uses a case-based approach to observe the trade-offs in the first phase of transport infrastructure development, and then, in the second stage, further explores the trade-off variables in the transport operations strategy under the China-Pakistan Economic Corridor (CPEC). The results from the three cases of the parallel route system of the CPEC indicate that trade-off is an easily understandable and applicable method, which can foresee the operational gains or compromises for significant welfare of the regions. The implications of the trade-off are two fold, first is the "importance" of the trade-off, which is related to its impact on operational competitiveness. The other is the "sensitivity" of the trade-off, in terms of the change that will be caused to one variable when changing the other. The trade-off concept can be used for several landlocked transport corridors to achieve a competitive edge in transit trade.

Cím:	Role of institutions in promoting finance in emerging markets: A panel data analysis / Arfia Aman, Muhammad Asif Khan, Mohammed Arshad Khan, Ahsanuddin Haider, Judit Oláh, Veronika Fenyves
Dátum:	2023
ISSN:	1932-6203
Megjegyzések:	Differences in institutions have garnered much attention in recent years as one of the pri- mary reasons for long-term economic performance, and a vast corpus of theoretical and empirical research demonstrates that financial development can have a substantial impact on economic and financial performance. In fast-growing emerging markets, the demand for financial services has considerably increased, which amplified the need for an efficient regu- latory framework to deal with the sensitive nature of financial activities. Surprisingly, the existing literature on the impact of institutions and finance is focused on developed econo- mies, while emerging markets are rarely focused on. Since emerging markets are becoming increasingly important as a result of the swift evolution of institutional and financial transfor- mation, it is crucial to examine how the growth of financial markets reacts to institutional quality. This study investigates the role of institutions in promoting finance in emerging econ- omies using the balanced panel dataset of 21 emerging market. Given the endogenous rela- tionship between institutions and finance, the paper applies a two-stage least squares estimator to test the settler mortality hypothesis in this context. Aligned with theoretical intui- tion, the empirical result shows that settler mortality is a relevant instrument to institutions. Furthermore, the study performs robustness, using framework that deals with heterogene- ity, and cross-section dependence. This empirical effort validates La Porta`s Law and Finance Hypothesis in the context of emerging markets. The results of the study are found robust across the variety of alternative measures of institutions and finance, and standard error correction specifications. Therefore, the study offers useful insight into policy implications.

Cím:	Natural resources and financial development: The role of institutional quality / Muhammad Atif Khan, Lulu Gu, Muhammad Asif Khan, Judit Oláh
Dátum:	2020
ISSN:	1042-444X
Megjegyzések:	This study investigates the natural resource rent and financial development nexus by sub-suming the critical role of institutional quality in this paradigm in a sample of 87 Emergingand Developing Economies (EMDEs), during the period from 1984 to 2018. The findingsdemonstrate that natural resources rent undermines finance and supports the naturalresource curse hypothesis in the financial sector of EMDEs. The institutional quality hasa significant positive impact on finance and it positively moderates the resource-financenexus. We argue that institutional quality follows some channels through which the natu-ral resource curse operates and turns the resource curse into a blessing for the financialsector. Furthermore, the results document a threshold effect of institutional quality inthe resource-finance relationship. Precisely, we find that natural resources rent positivelyexplains finance, once a certain threshold level of institutional quality is attained - belowwhich the natural resources rent becomes a curse, and hinders financial development.Therefore, policy attentions are recommended to promote finance by efficient utilization ofnatural resources through promoting and maintaining institutional quality beyond a certainthreshold level, and incorporating its vital role. Our results are robust to the use of differentsamples, alternative specifications, and alternative measures of finance and institutionalquality, and are practically useful to the policymakers concerned about EMDEs.

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:	Sustainable growth rate, corporate value of US firms within capital and labor market distortions: The moderating effect of institutional quality / Tanveer Bagh, Mirza Muhammad Naseer, Muhammad Asif Khan, Paula Pypłacz, Judit Oláh
Dátum:	2023
ISSN:	2083-1277 2353-1827
Megjegyzések:	Research background: Understanding how distortions in capital and labor markets affect corporate value and sustainable growth is crucial in today's economy. These distortions can disrupt resource allocation and economic sustainability. Additionally, the role of institutional quality in shaping these dynamics requires thorough exploration. Purpose of the article: We quantify the effect of capital and labor market distortions on corporate value and sustainable growth rate (SGR) and how this association is moderated by institutional quality. Methods: Stemming from the sample criteria, we calibrated a final sample of 1971 United States-listed manufacturing firms for 2012-2022. This research offers insights into market inefficiencies and institutional effects. Progressing towards objectives, we use advanced techniques like feasible generalized least squares and generalized methods of moments. These methods help us rigorously analyze complex relationships among study variables. Findings & value added: Three key findings emerge: first, capital and labor market distortions have a negative and significant influence on corporate value and sustainable growth. Our primary finding implies that increasing distortions significantly reduce sustainable growth's value and potential. Second, we find institutional quality has a positive significant effect on corporate value and sustainable growth. Third, institutional quality positively moderates the association between capital and labor market distortions, corporate value, and sustainable growth. Findings suggest that institutional quality, as a potential mechanism, improves the efficiency of resource allocation and optimizes the sustainable economic system to lessen the negative effect of factor market distortions on corporate value and SGR. Besides, we conduct robustness checks to validate our findings. Finally, we offer policymakers and stakeholders actionable insights.

Dátum:	2020
ISSN:	2071-1050
Megjegyzések:	The purpose of innovation is to consume fewer natural resources in order to create sustainable performance; therefore, innovation can ease the pressure of the ecological load and promote the sustainable development of the economy. Taking the 269 enterprises listed on the main board of the electronic information industry from 2010 to 2019 as samples, using the threshold panel data model, the nonlinear relationship between the knowledge-based network structure hole and the short-term and long-term innovation performance of the enterprises were studied, and the threshold e ect of R&D investment intensity was discussed. When the R&D investment intensity is from 1.96% to 15.96%, the knowledge-based network structure hole has a significant positive impact on short-term innovation performance. When the R&D investment intensity is from 5.72% to 10.64%, the knowledge-based network structure hole has a significant positive e ect on long-term innovation performance. Lower R&D investment intensity can make the knowledge-based network structure hole promote the increase of short term innovation performance, but to make the knowledge-based network structure hole have a positive impact on long term innovation performance, the R&D investment intensity should be increased by more than 5.72%. When R&D investment intensity is not higher than 15.96%, the knowledge-based network structure hole has a significant positive impact on short term innovation performance, but to make the knowledge-based network structure hole maintain the positive e ect on long term innovation performance, R&D investment intensity should not exceed 10.64%. Therefore, enterprises should be guided to optimize the knowledge-based network structure according to the R&D investment intensity in order to improve the short term and long-term innovation performance of an enterprise. These research results can help enterprises to save resources and promote the sustainable development of the economy.

Megjegyzések:	The study is conducted to find out the impact of the country- and corporate-level governance and firm internationalization on stock liquidity of 120 listed firms in Japan, Hong Kong, Pakistan, and India. Panel data is used in the current study. The annual time span covered in the current study is 10 years. The current study explores results based on secondary data. The findings of the 'robust panel corrected standard error' estimator shows that the internationalization strategy of firms positively influences the stock liquidity. The internationalization strategy of multinational corporations proves to be an effective methodology for improving stock liquidity in the home market as well as abroad. The study also shows that a stronger relationship exists between stock liquidity and internationalization in those countries where the regulatory settings are effective, the judiciary system is efficient and shareholders' rights are protected. Corporate governance and stock liquidity are negatively associated. The study also finds a negative relationship between country-level governance mechanisms and stock liquidity. Whereas the 'robust panel corrected error' estimator shows a positive association between corporate governance mechanisms and firm internationalization. The study depicts that effective corporate governance motivates multinational companies to expand their business abroad.

Megjegyzések:	Considering the importance of foreign direct investment (FDI) inflows for the sustainable economic advancement of a host country, this paper investigates the financial development and FDI nexus, using institutional quality as a moderator. The sample consists of 79 Belt and Road Initiative (BRI) partner countries, as these countries are entering a new age of integration, foreign trade, and mutual development. The empirical findings of conventional and robust estimators show that the financial development of BRI host countries significantly attracts FDI, while the institutional quality plays a significantmoderating role in this relation. The in-depth analysis offers the insight that financial markets are less attractive to FDI relative to financial institutions. Thus, policymakers are advised to uphold sound financial institutions to make the country more attractive to overseas investors, while concentration on financial markets may multiply the benefits of FDI. The results are robust to alternative proxies of the key variables and alternative methodologies.
