Electronic methods are already used in money transfer and credit cards transactions and electronic money and checks, which can substitute cash and coins, are being discussed. Recently, the Acts of Electronic Draft have been enacted, in order to make the money in the market flow efficiently. Also electronic bill of lading has been adopted for the practical use of international shipments. However, despite of the effort from the academia and practice, investments to stocks, especially in the stock exchange, is not quite perfectly electronic. Japan enacted a relevant act in 2004 which make its stock market totally dematerialized. This writing summarizes some issues in interpretation that arise in the course of operation of the Stock Electronic Registration System at the present time of 6 months after it came into effect and its purpose, by doing so, is to prevent in advance the kind of problems in introducing the similar system to Korea.

Purpose Since the Bitcoin, which was the first virtual currency, was made at 2009, almost 1,000 virtual currencies appeared onstage in the world. Even though virtual currencies have the function of money as a medium of exchange or contract, any of those has not yet entered the commercialization stage. Instead, some of the virtual currencies show the nature of investment assets. In the case of virtual money investment, users tend to use all the information of the world because information transfer is very easy and capital movement is almost free between different countries. In addition, as the transaction sizes of virtual currencies increase, a virtual currency price is no longer independent and is likely to be affected by the prices of other virtual currencies. Therefore, it is necessary to understand the influence among virtual currency markets, which helps successful implementation of investment strategies. Design/methodology/approach This study focuses on the investment product function of virtual money and conducts the analysis using the time series model used in the financial and economic areas. In this paper, we try to analyze the return and volatility transfer effect of virtual money markets through GJR-GARCH model. Findings This study is expected to find out whether we can make market forecasts through reflecting changes in other markets. In addition, we can reduce the trial and error of user decision making by using the information on the yield and volatility transition effect derived from the research results, and it is expected to reduce the opportunity cost of users.

Purpose - The adjustment of one country's monetary policy can cause the macroeconomic change of other countries. Due to this, this paper attempts to analyze the impact of China's monetary policy on South Korea's exchange rate. Research design, data, and methodology - Based on the flexible-price monetary model, sets of annual time series from 1980 to 2017 are employed to perform an empirical estimation. The vector error correction model is also used to exploit the short-run relationship between both of them. Of course, the South Korea's real GDP, the China's real GDP, South Korea's interest rate, the South Korea's interest rate and the South Korea's monetary supply are treated as independent variables in this paper. Result - The long-run findings reveal that the China's money supply has a negative effect on South Korea's exchange rate. Respectively, the short-run findings depicts that the China's money supply has negative a effect on South Korea's exchange rate. Of course, other variables selected in this paper also have an effect on South Korea's exchange rate whatever positive or negative. Conclusions - As the empirical evidence shows, the China's monetary policy has a negative effect on South Korea's exchange rate whenever in the long run or in the short run.

Purpose - The exhibition is one of the critical distribution channels that leads to mass sales of products. Servicescape is considered as an effective means facilitating consumers' purchasing behavior. The objective of this research is to examine the effects of servicescape of the exhibition on consumer's purchasing behavior measured by time spent, the number of consultations, the number of items purchased, and amount of money spent. Research design, data, and methodology - Servicescape was divided into four main components: 'spatial layout/functionality', 'ambient condition', 'design/artifacts', and 'human factor'. Based on previous studies, this study hypothesized that servicescape dimensions first influence consumer's shopping duration and the number of consultations which in turn, affects consumer's actual purchase. A total of 407 samples were collected from attendees in Baby Expo taken place in Kyunggido, South Korea. The data were used to assess overall fit of the proposed model and test hypotheses using structural equation modeling. All the constructs had acceptable levels of composite reliability and convergent and discriminant validity. Results - The results showed that except for 'spatial layout/functionality', all components of servicescape had a significant influence on consumer's shopping duration in the exhibition. Except for 'design/artifacts', other factors of servicescape did not show a significant effect on 'the number of consultations'. Interestingly, 'design/artifacts' exerted a significant negative effect on 'the number of consultations'. As expected, 'time spent' and 'number of consultations' showed significant effects on both 'the number of items purchased' and 'amount of money spent'. Conclusions - The results offer some insights into the effect of servicescape on facilitating consumers' purchasing behavior in the context of the exhibition. Theoretically, this study provides a new type of conceptual framework that verifies the relationships between not only servicescape and purchasing behavior, but also purchasing behavior-related variables. In addition, this study supports the concept of a dark side of servicescape. With regards to practical implications, this study suggests that exhibition organizers should put more efforts in facilitating consumer's desire to stay. More importantly, organizers need to keep in mind that excessive emphasis on 'design/artifacts' to increase consumers' shopping duration can cause a side effect that reduces opportunities for interactions with customers.

Purpose: The aim of this study is to explore the dynamic linkage between conditional stock market volatility and macroeconomic uncertainty of Bangladesh. Research design, data, and methodology: This study uses monthly data covering the time period from January 2005 to December 2018. A comprehensive set of macroeconomic variables, namely industrial production index (IP), consumer price index (CPI), broad money supply (M2), 91-day treasury bill rate (TB), treasury bond yield (GB), exchange rate (EX), inflow of foreign remittance (RT) and stock market index of DSEX are used for analysis. Symmetric and asymmetric univariate GARCH family of models and multivariate VAR model, along with block exogeneity and impulse response functions, are implemented on conditional volatility series to discover the possible interactions and causal relations between macroeconomic forces and stock return. Results: The analysis of the study exhibits time-varying volatility and volatility persistence in all the variables of interest. Moreover, the asymmetric effect is found significant in the stock return and most of the growth series of macroeconomic fundamentals. Results from the multivariate VAR model indicate that only short-term interest rate significantly influence the stock market volatility, while conditional stock return volatility is significant in explaining the volatility of industrial production, inflation, and treasury bill rate. Conclusion: The findings suggest an increasing interdependence between the money market and equity market as well as the macroeconomic fundamentals of Bangladesh.

Purpose - The purpose of this paper is to analyze the relationship between the real exchange rate and the output, which is based on the macroeconomic equilibrium theory in China. Its aim will be to verify whether the change in the real exchange rate has a significant effect on the output or not. Research design, data, and methodology - This study endeavors tries to investigate the correlation among economic variables under the macroeconomic market (the commodity market and the money market) equilibrium. So, time-series data from 1990 to 2016 is applied to establish a vector auto-regression (VAR) model so as to perform an empirical analysis. Results - The empirical results reveal that an increase in the real exchange rate will result in an increase in the output in the short run. However, the empirical results also indicate that this kind of mechanism cannot work in the long run. Conclusions - The effect of a decrease of real exchange rate on output is significant in the short run. Also, this paper suggests that the total supply and the total demand can promote economic growth. The fiscal and money policy play a significant role in economic growth in China as well.

A nuclear power plant requires a huge amount of initial investment and long construction lead time. As we expect that there may exist a relationship between investment and construction lead time, a number of researchers have reported that nearly a half of investments is incurred due to time factors such as the time value of money and inflation or escalation rates. Therefore, we investigated in this paper a relationship between the initial investment and the construction lead time of a nuclear power plant construction, and proposed a method for a trade-off analysis between the annual equivalent worth and the investment alternatives to reduce the construction lead time. Finally, we presented a real case to numerically explain the steps of the method presented in this paper.
