Regulatory sentiment refers to the market's subjective evaluation of regulatory reform and is one of the most widely adopted indicators to those charged with implementing and diagnosing regulatory policies. The use of regulatory sentiment in advanced analysis has become universal, albeit it is often limited due to difficulties in articulating consistent and objective quantitative indicators that can meticulously reflect market sentiment overall. Thus, despite ample effort by scholars to read the economic impact of regulatory sentiment in the real economy, causal links are difficult to spot. To fill this gap in the literature, this study analyzes a regulatory sentiment index and economic performance indicators through a text analysis approach and by inspecting diverse tones in media articles. Using different stages of tests, the paper identifies a causal relationship between regulatory sentiment and actual economic activities as measured by private consumption, facility investment, construction investment, gross domestic investment, and employment. Additionally, as a result of analyzing one-unit impulse of regulatory perception, the initial impact on economic growth and private investment was found to be negligible; this was followed by a positive (+) response, after which it converged to zero. Construction investment showed a positive (+) response initially, which then rapidly changed to a negative (-) response and then converged to zero. Gross domestic investment as the initial effect was negligible after showing a positive (+) reaction. Unfortunately, the facility investment outcome was found to be insignificant in the impulse response test. Nevertheless, it can be concluded that it is necessary and important to increase the sensitivity to regulations to promote the economic effectiveness of regulatory reforms. Thus, instead of dealing with policies with the vague goal of merely improving regulatory sentiment, using regulatory sentiment as an indicator of major policies could be an effective approach.

Purpose - The aim of this study is to develop an empirical model of the effects of traditional market service quality factors on customer value, relationship quality, and behavior. The specific objectives of the study are as follows: 1) to classify study objects into cultural tourism markets and non-cultural tourism markets as well as to verify the differences in service quality among the two markets and, 2) to present practical service marketing methods that fit with the characteristics of the traditional markets by amending the five quality evaluation items of SERVQUAL (a multiple-item scale for measuring service quality)to suit the characteristics of the traditional markets and establish the relationship among customer value, relationship quality, and behavior intention. Research design, data, and methodology - The study methods of empirical investigation are as follows. First, this study selected for a study object the Suwon Paldalmun Gate Market to represent the cultural tourism market, and general traditional markets to represent the non-cultural tourism market. This study also conducted personal interviews in order to increase the response rate and collected a total of 418 responses between March 18, 2014 and April 05, 2014. The total of 418 responses used for this study excluded 14 responses that had either misleading information or missing values. Results - This study verified the perceived differences of service quality based on traditional market specialization through an independent sample t-test. It appeared that the perceived service quality of the cultural tourism market was generally higher than that of the non-cultural tourism market. This study executed a path analysis in order to examine the effects of service quality factors on customer value, relationship quality, and behavior intention. This study also comprehensively analyzed the specialized market and non-specialized market separately. Although there were some differences among the results, the overall results were uniform. It appeared that convenience, reliability, and empathy, among the service quality factors, exerted meaningful effects on customer value. On the other hand, convenience, reliability, responsiveness, and empathy, excluding the tangibles, exerted meaningful effects on the relationship quality. In addition, it appeared that all service quality factors exerted meaningful effects on the customer value, relationship quality, and behavior intention. Therefore, the study verified that all of the hypotheses formulated in the study were generally adopted. Conclusions - The implication of this study may be classified into academic and practical implication as follows. With respect to the academic implication, it seems that this study is among the early studies to verify the differences between the cultural tourism market and the non-cultural tourism market. The practical implication of this study is that the perceived service quality, such as convenience, reliability, responsiveness, and tangibles, excluding empathy, was higher in the cultural tourism market than in the non-cultural tourism market. This means that customer satisfaction is enhanced by governmental aid such as hardware, software, and information and communications technology.

본 연구는 변동성의 비대칭적 반응과 관련하여 주식시장에 비하여 상대적으로 많은 연구가 이루어지지 않은 채권시장에 대해서 살펴보았다. 이를 위하여 국채시장과 유가증권시장을 대상으로 분석을 실시하였으며, 분석모형은 가장 일반적인 대칭모형인 GARCH모형과 비대칭모형으로는 GJR-GARCH모형을 이용하였다. 실증분석 결과를 요약하면 다음과 같다. KOSPI수익률의 경우에는 변동성의 비대칭성을 나타내는 계수와 모형의 적합성을 나타내는 우도비(LR) 통계량이 유의수준 1%에서 유의한 것으로 나타나고 있어서, 기존의 선행연구들과 같이, 주식시장에 비대칭적 변동성이 존재한다는 것을 재확인할 수 있다. 반면에 국고채수익률의 경우에는 비대칭적 변동성을 나타내는 계수가 통계적으로 유의하지 않고 모형의 적합성을 검정하는 우도비(LR) 통계량 또한 유의하지 않은 것으로 나타나고 있다. 이는 국고채수익률의 경우에는 비대칭적 변동성이 존재하지 않으며, 변동성의 군집화현상과 시간 가변적인 특성을 포착하기 위해서 대칭모형인 GARCH(1,1)모형을 이용하는 것만으로 충분하다는 것을 보여주고 있다. 이러한 결과는 미 재무성채권을 대상으로 한 연구에서 채권시장에는 비대칭적 변동성이 존재하지 않는다는 Hoti, Maasoumi, McAleer & Slottje(2005)와 Cappiello, Engle & Sheppard(2006)의 연구결과와도 일치하는 것이다.

This study investigates the perception of different fabrics by consumers when provided with a video clip with rustling sounds of the fabric. We utilized sportswear products that are currently on the market and evaluated the emotional response of internet shoppers by measuring the physiological and psychological responses. Three kinds of vapor-permeable water-repellent fabric were selected to generate video clips each containing the fabric rustling sound and images of exercise activities wearing the sportswear made of the respective fabric. The new experimental website contained the video clips and was compared with the original website which served as a control. 30 subjects, who had experience to buy clothing online, took part in the physiological and psychological response to the video clip. Electroen-cephalography (EEG) was used to measure the physiological response while the psychological response consisted of evaluating accurate perception of the fabric, satisfaction, and consumer interest. When we offered video clips with fabric's rustling sound on the website, subjects answered they could get more accurate and rapid information to decide to purchase the products than otherwise they do the shopping without such information. However, such rustling sounds somewhat annoy customers, as proved psychological and physiological response. Our study is a critical step in evaluating the consumer's emotional response to sportswear fabric which will promote selling frequency, reduce the return rate and aid development of new sportswear fabric further evolution of the industry.

본 연구는 중국 경제의 성장에 따른 중국 주식시장과 한국 주식시장간의 동조화에 대한 연구의 일환이다. 저자가 관심을 가지는 부분은 한국과 중국의 1시간 30분의 시차에 따라 발생하는 중국시장의 개장충격 즉, 시가갭에 대한 한국시장의 장중반응이다. 금융위기 이후 중국 주식시장에서 발생하는 충격은 이전보다는 크게 영향을 주고 있는 것으로 체감됨에 따라 실제 한국 시장의 10시 30분 이후의 수익률과 변동성을 살펴봄으로써 중국시장의 시가갭의 영향이 증가해오고 있는지를 실증적으로 분석하고자 하였다. 분석기간은 2008년 1월부터 2010년 4월까지 총 28개월이며, 수익률 전이 및 변동성 전이를 연속회귀에 의해 분석함으로써 시간의 흐름에 따라 계수의 크기와 유의성의 변화를 관찰하였다. 그 결과, 중국 시장의 시가갭은 한국 시장의 10시 30분 이후 5분내외의 누적수익률 및 변동성에 유의적인 양의 영향을 미치고 있으며, 이러한 경향은 최근에 들어서야 크게 증가하고 있는 것으로 분석되었다. 그리고 10분이후의 누적수익률 및 변동성에 미치는 영향은 거의 없는 것으로 보여 중국시장의 개장충격은 한국시장에 약 5분정도 상당한 영향을 줄 수 있는 것으로 파악된다. 무엇보다 중요한 점은 이러한 장중의 영향이 최근에 들어 일관되게 증가하고 있다는 점이며, 중국의 성장에 따른 영향력이 커지고 있음을 실증적으로 알 수 있게 되었다는 점에서 다양한 후속 연구가 기대된다. 특히 아시아 지역의 개장시차의 차이에 따른 수익률 및 변동성 전이의 흐름으로 확장될 수 있기를 바란다.

Deregulation and restructuring of electric industry change the fundamental nature of electric business which will be coordinated by the evolved market structures such as spot market with pool and bilateral transaction structure, forward market and future market. Introduction of competition can significantly change the system operation in near-terms as well as long-run generation expansion planning Previous centralized planning by monopoly utilities which was guided for the public service purpose will be replaced by decentralized investments plan by individual generation companies in response to commercial incentives. This paper reviews WASP model as a centralized planning tool and presents a methodological analysis of generation expansion planning in deregulated power systems. It stresses how affects the process of planning new generation investments by the introduction of competition and how maintains proper fuel mix and continuously sustains system reliability under deregulated environments.

A project to build a large oceanographic research ship was proposed to improve the level of ocean research. This paper attempts to measure the non-market benefits of the project. To this end, the dichotomous choice contingent valuation method is used. In particular, the recently proposed one and one-half bounded model is applied. The model can reduce the potential for response bias compared to the double bounded model, while maintaining much of its efficiency. Moreover, in order to deal with zero WTP observations, a spike model is adjusted for our data. A survey of 500 randomly selected households was implemented in the Metropolitan area. The respondents were asked in person-to-person interviews about how they would be willing to pay for implementing the project. Overall, respondents accepted the contingent market, and were willing to contribute a significant amount (3,244 won), on average, per household per year. The aggregate value of the project nationwide would amount to approximately 40.1 billion won per year.

This study aims to examine the dynamics of price changes and trading volume of Kuala Lumpur Options and Financial Futures Exchange (KLOFFE) from 2000 to 2008. With augmented analysis, our results support two hypotheses. First, under information spillover, our findings support noise traders' hypothesis as the time span for variance of past trading volume to cause variance of current return is found to be asymmetric under bull and bear markets. Second, looking at the dynamic relation between volume and volatility of price changes, our findings support Liquidity-Driven Trade hypothesis as past trading volume and subsequent volatility of return exhibit positive correlation. In terms of investors' behavior in response to the news, we find that investors are more risk taking in bull market and more risk reverse in bear market. Our study suggests that investors should adjust their strategy in the futures market in a dynamic manner as the time span of new information arrival is not consistent. Also, uninformed investors with information asymmetry should expect noninformational trading from informed investors to establish their desired positions for better liquid position.
