This research examined consumption-based carbon emission reduction by nuclear energy consumption and environmental tax while considering the context of trade globalization in the highest five emitter nations from 1990 to 2020. This study used various empirical methodologies, including preliminary analysis to check the stationarity and cointegration, the CS-ARDL for long-run analysis, CCEMG, AMG for robustness, and the D-H causality test for short-term pairwise causation. The results indicated that nuclear energy consumption, environmental tax, and trade globalization help to mitigate consumption-based carbon emissions while economic growth and population density boost carbon emissions. Furthermore, the results also found two-way casual connection exists between nuclear energy consumption, population density, and consumption-based carbon emissions. Thus, the results emphasize the need for government policies that encourage nuclear energy and environmental tax as a strategy to reduce carbon emissions and achieve and maintain environmental development.

Purpose - This paper aims to compare and analyze the co-movements and information spillover effects between the international commodity futures markets and the South Korean stock markets during the COVID-19 and the 2008 financial crises. Design/methodology - The DCC-GARCH model is used in the co-movements analysis. In contrast, the BEKK-GARCH model is used to evaluate information spillover effects. The statistical data used is from January 1, 2005, to December 31, 2022. It comprises the Korea Composite Stock Price Index data and daily international commodity futures prices of natural gas, West Texas Intermediate crude oil, gold, silver, copper, nickel, soybean, and wheat. Findings - The results of the co-movement analysis were as follows: First, it was shown that the co-movements between the international commodity futures markets and the South Korean stock markets were temporarily strengthened when the COVID-19 and 2008 financial crises occurred. Second, the South Korean stock markets were shown to have high correlations with the copper, nickel, and crude oil futures markets. The results of the information spillover effects analysis are as follows: First, before the 2008 financial crisis, four commodity futures markets (natural gas, gold, copper, and wheat) were shown to be in two-way leading relationships with the South Korean stock markets. In contrast, seven commodity futures markets, except for the natural gas futures market, were shown to be in two-way leading relationships with the South Korean stock markets after the financial crisis. Second, before the COVID-19 crisis, most international commodity futures markets, excluding natural gas and crude oil future markets, were shown to have led the South Korean stock markets in one direction. Third, it was revealed that after the COVID-19 crisis, the connections between the South Korean stock markets and the international commodity futures markets, except for natural gas, crude oil, and gold, were completely severed. Originality/value - Useful information for portfolio strategy establishment can be provided to investors through the results of this study. In addition, it is judged that financial policy authorities can utilize the results as data for efficient regulation of the financial market and policy establishment.

Purpose - Underdog positioning is often used to evoke a positive attitude when interacting with consumers. However, little research has been conducted on the market competition structure and innovation contexts in which underdog positioning produces the most impact. This research aims to investigate unexplored boundary conditions of underdog positioning and addresses two issues: market structures (oligopoly vs monopolistic competition) and perceived firm innovativeness (PFI). Design/methodology - Two one-way ANOVA designs (market structures: monopolistic competitions vs. oligopoly; perceived frim innovativeness: strong vs. weak) were randomly assigned to 297 graduate and undergraduate students (52 % female) majoring in business. Study 1 examined the effect of underdog positioning on consumer attitudes in the different market structures. Study 2 investigated the relationship between underdog effect and consumer attitudes through viewing conditions that varied in PFI. Findings - Drawing on the results of the study, the authors conclude that underdog positioning is effective to generate more positive consumer attitudes when employed in the market structure of monopolistic competition rather than oligopoly. Moreover, both underdog and top dog positioning are likely to generate more positive consumer attitudes when accompanied with strong PFI than weak PFI. Originality/value -This is the first study to distinguish between monopolistic competition and oligopoly market structures with underdog positioning as well as to demonstrate a positive effect of PFI, regardless of the type of brand narratives.

The European Union Vietnam Free Trade Agreement (EVFTA) took effect on August 1 paving the way for increased trade between the EU and Vietnam; this marked a huge turning point for the Vietnamese economy. Agriculture products, especially fruits, must be listed when it comes to Vietnam export industries that profit the most from EVFTA. After a period of study, with the desire to contribute to the improvement in the efficiency of Vietnam's agricultural products to the EU, the researchers want to assess the impact of the EVFTA on the flows of Vietnamese fruits to the EU market. The study uses a quantitative analysis method via the WITS-SMART model with data on export turnover and tariff reductions in parallel with the analysis of changes in factors affecting the trade flows of fruits between the two markets when the EVFTA takes effect. As a result, Vietnam's fruit importing from the EU is expected to escalate by 29.18% in 2021, while the flow of export will only inch up by 0.955%, which is rather low compare to the increase in import value. Hence, effective policies must be introduced in Vietnam to innovate production methods and increase product quality, so that the EVFTA can be used to boost Vietnam's fruit exports to the EU.

From the reunification of Germany we can learn much for the reunification of Korea. That particularly applies for the dispute resolution of the trade relations between both states. The domestic trade relation, which was the only contractually regulated relation between two states for a long period of time, played a crucial role in the reunification of Germany, In this research paper, we examine how the economic disputes in divided Germany had been settled, and consider for the amicable economic relations between south and north Korea, what can we learn from that. In Germany, the disputes from the trade relations could be settled via the civil procedure, because the judicial codes of both German states were the same until 1975, However, that does not apply in Korea, as two Koreas have another law and another court system, from the start. We argue that arbitration is the best way for the completion of the economic disputes. Besides the general advantages of the arbitral procedure, the arbitration is particularly suitable to regulate the economic disputes from Korea-Korea relations, because of glaring differences of the legal status and reality of both countries. Furthermore, the standing arbitral tribunals would be in the economic relations between two Koreas more effectively than the ad-hoc arbitral tribunals. The ad-hoc arbitration generally requires a lot of time to setting up an arbitral Oibunal. For the rapid and obligatory settlement of dispute, the Convention of Currency, Economic and Social Union between West and East Germany 1990(Staatsvefrag zur Wahrungs-, Wirtschafts- und Sozialunion zwischen der Bundesrepublik und der DDR) also planned the institutional arbitration. The organizational support of the internal-Korean arbitration can take place via already existing institution, namely in south Korea 'The Korean Commercial Arbitration Board' Periodic decision reports and publication of substantial awards at the early stage seem appropriate.

With the advent of the Free Trade Agreement between Korea and the U.S. and an increase in trade volume between the two countries, the possibility of commercial disputes has escalated among international merchants. It has been well-known that arbitration as an alternative dispute resolution is an efficient way to resolve international commercial disputes. When arbitral awards are enforced in the judicial system, the court will inevitably have to be involved with the enforcement procedures. The court is a typical legal entity to confirm arbitral awards. Through a confirmation process, the winning party obtains the same legal status of final judgment rendered by the court. However, a winning party in arbitration will have to overcome a legal hurdle in the enforcement process of arbitral awards. This article aims to investigate how the courts control the arbitration practices and what the basic legal issues in the enforcement of arbitral awards are. The US Federal Arbitration Act is investigated, while relevant cases are reviewed and updated for legal analysis.

In this paper, we propose novel two-way relaying scheme in which number of two users transmit the signal to number of two destination. The scheme is difference with conventional multi-hop two-way relay scheme in which number of two users exchange the each signal. In the conventional scheme, each user have to perform back-propagating self-interference method to remove the own signal from received signal. It occurred to increase the complexity for signal processing at the user. To overcome the problem, we apply the Pre-cancellation which can reduce the process of back-propagating self-interference to our proposal network Simulation result show that proposal scheme outperform the convention multi-hop two-way relay scheme. Also we analysis the trad-off between performance and complexity accordance with using Pre-cancellation method.

Purpose - The principle aim of this study is to further investigate the relationship between market diversity and export performance. We examine the benefits and costs of geographic market diversity regarding the number of countries exported to by firms on their export performance. Based on the financial risk reduction model and the entry costs model, we propose a way to incorporate the costs and benefits aspects of market diversity. Design/methodology - To empirically investigate our research question, the curvilinear relationship between market diversity and export performance, we built a secondary panel data set between 2015 and 2019, containing 17,863 observations of Korean exporting companies. A generalized least squares panel estimator with fixed effects was employed to test the hypothesis, and the statistical package, Stata 14, was used. Findings - Our main findings are as follows: As market diversity increases, export performance increases because exporters can diversify and reduce financial risks in export markets. However, the relationship between the two does not grow. As it peaks, the entry costs increase due to the high market diversity, thereby outweighing the benefits, leading, eventually to decrease in the export performance. Consequently, there is an inverted U-shaped relationship between market diversity and export performance. Originality/value - In the export and trade literature, the impact of market diversity on export performance has not been addressed yet, despite the importance of this subject. Many scholars have assumed a positive linear relationship between the two, considering only the decrease in market risks as the number of overseas markets increases, without examining the increase in the entry and management costs. Therefore, our study contributes by providing a new perspective for analyzing the characteristics and outcomes of market diversity.

This paper attempts to provide a way to improvement in trade & commerce between Korea and Russia, analyzing the influence of the circumstances of the Russian economy on economic relations between the two countries. The study briefly reviews the current situation of the Russian economy, and tries to examine the strong points to be considered as leverage for cooperation and the weak points to be overcome. Previous studies have determined that the Russian economy has unlimited potential for growth, because it is endowed with abundant resources, and has a government willing to reform for the opening of the economy, as well as high-quality labor. However, the economic structure is vulnerable to impact of the worldwide financial crisis. It is not possible to overlook its institutional fragility and vulnerability such as a corrupt bureaucracy or a relatively large black market. These undesirable factors may not only undermine the basis of Russia economy but also a hindrance to economic cooperation by increasing economic uncertainty. This paper attempts to analyze comprehensively the socio-economic factors that influence the open-economy of Russia, and to illustrate strategies for improvement in trade and commerce through the viewpoint of Korean firms that are already in business or are trying to enter in the near future. Some measures to improve their economic cooperation are suggested at the end.
