For many firms, customers are their most valuable assets. This is a shift in the interest of managers and researchers from a traditional focus on product management to a more recent focus on customer management. And they manage their customers with relationship marketing. Despite the recent academic interest in the study of customer equity, prior research has focused on brand equity and limited relationship mediated variate such as satisfaction, commitment and trust. This paper suggests customer equity drives with mediated variate and examines how relationship marketing can generate drives of customer equity and influence on customer behaviors. The results are like this. First, customer equity drives include value, brand and relationship equity and they mediate between relationship marketing activities and customer behaviors. Second, financial, social and structural activities have significant impact on repurchase, positive word of mouth, and cross purchase through customer equity drives. Third, this study tried to organize literature on customer equity systematically. It will become the foundation of follow-up studies.

본 논문에서는 KOSPI200 지수선물의 분 단위 가격 데이터를 이용하여 거래비용을 고려한 옵션 복제 전략들의 성과를 비교하였다. 비교를 위해 사용한 옵션 복제 전략들은 (1)Black-Scholes 델타(delta) 전략, (2)Black-Scholes 델타 한도 전략, (3)Leland 전략, (4)Whalley-Wilmott 전략이다. 각 전략들은 옵션 복제를 위한 기초자산 거래와 관련된 두 가지 질문에 대한 답을 준다. 첫 번째 질문은 거래 시점에 관한 것으로, '언제 거래할 것인가'이고, 두 번째 질문은 거래량에 관한 것으로, '얼마만큼 거래할 것인가'이다. 본 논문에서는 현실적인 KOSPI200 지수선물 거래수수료(거래금액 대비 0.01%) 환경에서 잔존만기 1년인 유럽형 등가격 콜 옵션을 복제하는 경우를 실험하였다. 실험 결과 Leland 전략을 제외한 나머지 세 전략들의 복제 성과가 상대적으로 뛰어난 것으로 나타났다. 그러나 이들 세 전략들 간에는 복제 성과에 대해 뚜렷한 차이를 발견하기 어려웠다. 한편, 복제 종료 시점에서의 복제 손익에 큰 영향을 미치는 요인은 복제 오차(복제 포트폴리오의 만기 가치와 복제 대상 옵션의 만기 현금흐름의 차이)인 것으로 나타난 반면, 복제를 위한 기초자산 거래비용이 복제 종료 시점에서의 복제 손익에 미치는 영향은 적은 것으로 나타났다.

Simon and Sullivan(l993) estimated that clothing and textile related brand equity had the highest magnitude comparing any other industry category. It reflects that fashion brands reinforce the symbolic, social values and emotional characteristics being different from generic brands. Recently, Kim and Lim(2002) developed a fashion brand equity scale to measure a brand's psychometric properties. However, they suggested that additional psychometric tests were needed to compare the relative magnitude of each brand's equity. The purpose of this study was to recognize the psychometric constructs of fashion brand equity and validate Kim and Lim's fashion brand equity scale using the measurement invariance test of cross-group comparison. First, we identified the constructs of fashion brand equity using confirmatory factor analysis through structural equation modeling. Second, we compared the relative magnitude of two brands' equity using the measurement invariance test of multi-group simultaneous factor analysis. Data were collected at six major universities in Seoul, Korea. There were 696 usable surveys for data analysis. The results showed that fashion brand equity was comprised of 16 items representing six dimensions: customer-brand resonance, customer feeling, customer judgment, brand imagery, brand performance and brand awareness. Also, we could support the measurement invariance of two brands' equities by configural and metric invariance tests. There were significant differences in five constructs' mean values. The greatest difference was in customer feeling; the smallest, in customer judgment.

This paper examines consumption dynamics in relation to asset prices in Korea. Empirical analysis based on the error correction model shows that personal consumption is affected by changes in asset prices but the consumption converges to the long-run level of consumption corresponding to the total income flow in two years. This adjustment in consumption implies that the consumption error, reflected in the error correction term, should have predictability for the future consumption growth during the adjustment period. It is found that the error correction term has a long-run predictability for consumption over up to about 3 years; thus, confirming the error correction model. It is also found that housing prices have larger effects on consumption compared with stock prices in Korea. In addition, the effects of income and asset prices on consumption show bigger effects during contractionary period than expansionary period in business cycles. This paper also analyzes effects of asset wealth that reflects changes in both price and quantity. It is found that asset wealth has a long-run effect on consumption in addition to total income as determinants of consumption. Since wealth effects usually indicate the long-run effect of changes in asset wealth on consumption that is not explained by labor income, which is the proxy for human source of wealth, it is estimated with labor income used as a control variable. According to the estimation, the marginal propencity to consume out of asset wealth is approximately 2%. It means that 1,000won increase in asset wealth may lead to 20 won increase in consumption.

ICT environment to the survey released by the Bureau of Statistics 2012 Household Finance. Korean Welfare survey 24.9% of all households in financial assets, real estate is about three times more than 69.9%, respectively. The problem is that the information is slow and income deciles(deciles 1-4), a relatively high proportion of households with low(78.8 to 69%) of the real estate assets of the expansion of the world economy with low growth and low uncertainty, work from home due to the information changes in the structure of the economy, such as increases in real estate prices remain exposed to the risk of a phenomenon such as Pour House Pour Talent and low-income people is bound to be more serious symptoms. This low correlation is by constructing a composite asset portfolio, the weighted average risk of the individual assets while increasing overall revenue decrease that risk is based on the principle of portfolio by type and different areas in the ICT environment in a portfolio of real estate price index low correlation to financial assets by including the effect of dispersion stable complex asset portfolio and empirical Growth was divided.

The increased national utilization of Bitcoin results in multiple complications. Therefore, there are continuous debates on the subject, the main point being how to characterize Bitcoin's asset nature. The following study bases, focusing on the function value, justifies Bitcoin's asset characterization. Using regression analysis to construct relations between gold and indexes such as CPI, DXY, and S&P500 as well as the relation between Bitcoin and the previously mentioned indexes, the question of whether gold and Bitcoin reacted in a similar fashion to the same indicators was examined. The results conclude that Bitcoin has similarities with gold, showing that it is risk averse and an investable commodity in lieu to profitability when it comes to inflation and currency value. When considered with price volatility, the main force behind the function of investment asset, categorizing Bitcoin as a high-risk financial investment asset rather than as a currency within the system would be more effective for management.

Because bridges can cause more significant damage than other infrastructure a certain level of safety shall necessarily be secured for users. As most of bridges' service life become 20-30 years there will be a dramatic increase in the maintenance and repair cost but the budget and human resource will be limited. Asset management technique can help the efficiency in maintenance and budget management with the limited resource. For its application, there must be a way to evaluate how bridges provide service to users. The level of service can be quantified by a performance measure. This study introduces performance measures and an evaluation process for the determination of level of service. The evaluation results will be used as a fundamental information in the determination of maintenance/repair/management targets and in the decision making process of the bridge asset management.

This study tries to investigate the fundamental implications inherent in inventory asset information(specifically, unexpected inventory investment) by analyzing how the relationship between unexpected inventory investment and future operating performance. And we study how is the response of the stock market participants to the fundamental implications inherent in inventory asset information. Prior papers often assume the efficient market and they view the significant relation between stock prices and financial indicators as evidence of the contribution of such indicators to future earnings. Leading indicators are attracting the market's attention for equity valuation. We study whether one leading indicator (unexpected Inventories) forecasts future earnings, and whether market participants fully reflect the predictive ability when they sets share prices(Mishkin test, 1983). Our empirical results of the study are summarized as follows. Current unexpected inventory investment is negatively associated with future operating performance. Also, our evidence is that the stock market participants overprice the contribution of unexpected inventory investment when predicting future earnings. Furthermore, a hedge strategy that uses the overpricing gives significant future abnormal returns. The overall results help the users of financial reports, researchers of accounting, and the accounting principle setting body.
