Recently increasing in marketing or policy decision is the trend of reflecting big data, which, however, has yet to be used directly for the location analysis of public facilities in terms of urban planning. This study examined how the local currency big data, issued often recently by municipalities throughout the country, can be used for the decision-making to select the location of public facilities more rationally. It is such an interesting attempt to acquire the big data of local currency payments by local residents and directly apply it to analyzing the location analysis of public facilities they use. The big data of local currencies which are issued by most municipalities now in Korea will continue to extend its role as the public data. Relatively easily available for municipalities with low cost, it is expected to be used for various policy decisions in future. Although the analysis of big data can make more accurate results than conventional survey methods, however, local residents' participation should not be scaled down in policy decisions. Rather, they should be given the findings of this kind of scientific survey so as to extend the citizen-participatory decision-making model.

We focus on two kinds of game currency in online games, Game Money and Cash Money, and investigate how money expenditure behavior is explained by experience, achievement, and region as well as how the interplay among key variables differs between Game Money and Cash Money. The empirical analysis provides the following findings. First, experience increases Game Money expenditure whereas it lowers Cash Money expenditure, which suggests that gamers substitute gaming efforts for cash. Second, achievement is positively correlated with both kinds of game currencies. Finally, the relationship of money expenditure with experience and achievement is moderated by region. Specifically the negative effect of experience on Cash Money expenditure is more pronounced in suburban areas than in urban areas. The positive effect of achievement on Cash Money expenditure is also more pronounced in suburban areas than in urban areas. The authors conclude the paper with theoretical contributions and practical implications.

After COVID-19, interest in "sustainable tourism" increased, and the number of tourists who wanted to experience "sustainable tourism" also increased. However, there is a problem that the programs and methods for 'sustainable tourism' are not specific and diverse. In addition, since most of the interests of "sustainable tourism" focus on "environment" and "carbon neutrality," there are not many programs or government policies that can contribute to the community. Therefore, in this study, news data and review data were analyzed to suggest a method for promoting 'sustainable tourism'. First, in this study, major themes of sustainable travel were derived through news big data analysis. Through this analysis, policy themes and events of 'sustainable tourism' were derived. By analyzing news big data related to "sustainable tourism," we would like to analyze the reasons why sustainable travel has not been activated in Korea. Finally, in order to promote sustainable travel in Jeju island, we analyzed user review data of Jeju local currency, and propose a idea to coexist with the local community.

The paper is basically designed to investigate any existence of co-movement among foreign exchange market, goods market, and monetary market implemented by relative PPP and interest rate parity. And, rational expectation and GARCH-M model are employed for an empirical application. The result revealed that since the co-movement among the markets is hardly found, an efficiency of foreign exchange market is independent from any shocks from the goods market and the monetary market. Whereas, the exchange rate is strongly effected by a real interest rate parity. To this end, the real interest rate should be a key policy instrument to stabilize the foreign exchange market.

우리나라는 농경문화가 주류를 이루어 발달해 온 문화권에 속한다. 그러므로 우리의 전통생활문화에서는 농업의 특성과 지역공간에 기반을 둔 두레나 품앗이 등 공동체의 생활양식이 발달되어 왔다. 설날과 보름, 단오, 추석과 같은 명절의 세시풍속과 많은 전통문화의 요소는 농업ㆍ농촌과 밀접한 관계를 갖고 있으며 이는 도시보다는 농촌에서 보다 쉽게 유지되고 보존되어진다. (중략)

This study examines exchange rate volatility spillovers that affect the exchange rate volatility of Korean currency. For this study, the Japanese yen, British pound, Euro, and Canadian dollar are used as the currencies of developed countries, and the Thai baht, Indonesian rupiah, Singapore dollar, and Australian dollar are used as the currencies of the areas near Korea. The GARCH(1.1) model is employed for weekly data covering the period from January 2009 to December 2017. This study finds that the volatility spillovers from the Canadian dollar, Singapore dollar, and Australian dollar to the Korean won are significant, while the volatility spillovers from the Japanese yen, British pound, Euro, Thai baht, and Indonesian rupiah to the Korean won are insignificant. In terms of the economic system and structure, Japan, Britain, and European countries are at a higher level than Korea, while Thailand and Indonesia are at a lower level than Korea. Canada, Singapore, and Australia are almost at the same level as Korea. Therefore, these results appear to be derived from the phenomenon of exchange rate spillovers among countries with a similar economic system and structures, and contradict the literature, which has argued that exchange rates volatility spillovers occur among countries that are in the same area geographically.

The purpose of this paper is to examine the transmission of domestic and foreign real and monetary disturbances into a small country with heavy imports of intermediate goods, and to analyze how the wage indexation in a small country affects the transmission of foreign disturbances into a small country. We consider the two countries, a small country and the rest of the world, two goods, and rational expectations world model under flexible exchange rate system with perfect capital mobility. We find out that foreign disturbances are transmitted into a small country through the price channel, the foreign output multiplier channel, and the nominal interest rate channel, and the foreign real balance channel. We have conducted an empirical investigation by using the Korean data for a small country and the U.S. data for a large country to see how real and monetary disturbances originating from the US affects the Korean economy with wage indexation.

This paper investigates the existence of uncovered interest rate parity between the Korea-USA as well as the Korea-Japan. We may ascertain the existence of uncovered interest rate parity by examining the empirical relationship between real exchange rates and interest rate differentials in the Korea-USA as well as in the Korea-Japan. The empirical relationship between real exchange rates and interest rate differentials in the Korean-USA and Korean-Japanese economies is investigated using cointegration tests. In the context of this study, cointegration technique is appropriate to examine the relationship between two(or more) nonstationary time series. Also, this method is useful to detect the possibility that the nonstationarity in both series can be explained by a single factor. The empirical results support the nonexistence of a long run equilibrium relation between real exchange rates and interest rate differentials. Also, the results show that the nonstationarity cannot be explained by a single factor.

Traditionally, a congestion charge based on first-best congestion pricing theory, namely, the theory of marginal cost pricing theory, is equal to the difference between marginal social cost and marginal private cost. It is charged on each link so as to derive a user equilibrium flow pattern to a system optimal one. Based on this theory this paper investigates on the characteristics of first-best congestion pricing of multiple user class on road with variable demand, and presents two methods for analysis of social and spatial equity. For these purposes, we study on the characteristics of first-best congestion pricing derived from system optimal in time and in monetary unit, and analyze equity from this congestion pricing with an example network.
