The purposes of this study were (1) to understand how customers trade off one attribute against another when they choose a pizza restaurant, (2) to compare the importance of individual attributes with their relative importance and (3) to compare customers'brand choice patterns with the prediction of pizza restaurant operators. Empirical data for this study were collected from the customers (n=307) and operators (n=273) of flour famous pizza franchise restaurants in Korea, Pizza Hut, Mister Pizza, Domino's Pizza and Pizza Mall. The attributes and attribute levels for the hypothetical profiles were decided from the focus group discussion. A total of 16 profiles was selected from fractional factorial designs. The SPSS conjoint procedure was used to calculate utility scores and simulate profiles. The overall group statistics showed the relative importance of all attributes compared with one other. Taste was the most important attribute (32.48%) in choosing a pizza restaurant, followed by service (21.87%) , atmosphere (17.23%), price (15.17%) and speed of delivery (13.26%). There was a difference between the customers'ratings of the importance of the individual attributes and the ranking of the same attributes'relative importance as derived from the conjoint analysis. The operators rated service (26.54%) as also being important, as well as taste (27.76%), in choosing a pizza restaurant. The rankings of relative importance for pizza taste, service and price were statistically different in the customers'and operators'data (p < 0.001, p < 0.1, p < 0.5). Operators who want to differentiate themselves from their competitors should make decisions based on an increased understanding of their customers'brand choice decision process and measure the hidden needs of their customers.

대리점과 주유소에 정유사가 공급하는 휘발유의 공급가격의 동태적 가격조정을 오차수정모형을 이용하여 추정하고 분석하였다. 자사의 가격과 비용의 변화에 대한 비대칭적 가격조정을 추정하였을 뿐만 아니라, 타정유사 공급가격의 균형이탈에 대한 정유사 공급가격의 조정을 모형에 허용함으로써 정유사간 가격경쟁의 가능성도 살펴보았다. 추정 결과 다음과 같은 사실들을 찾아낼 수 있었다. 첫째, 정유사의 휘발유 공급가격은 환율과 국제제품가격에 대해 비대칭적 조정을 하고 있으나, 서로 반대방향의 조정이 나타나고 있다. 둘째, 정유사 공급가격은 자사가격의 균형이탈에 대해 신속한 가격조정을 하며, 비대칭적 조정을 하는 정유사도 발견되었다. 셋째, 타정유사 균형가격이탈에 대해 반응하여 가격을 조정하는 정유사들이 존재하며, 일부 주유소 공급가격에서는 타정유사 균형가격이탈에 대해서 경쟁적 가격조정이 나타났다. 이러한 결과들은 개별 정유사가 자기 고유의 가격비탄력적인 수요를 직면하고 있으며, 가격수준을 유지하기 위한 단기적 가격조정을 하는 암묵적 담합에 부합하는 가격조정 행태를 취하고 있으며, 일부 정유사의 주유소 공급가격의 경우에는 타사 가격변화에 경쟁적 가격조정을 하고 있음을 나타내는 것으로 볼 수 있다. 이는 휘발유시장의 가격경쟁을 유도하려는 정책을 고려한다면, 주유소시장부터 가격 경쟁적 환경을 조성하는 것이 경쟁촉진에 효과적일 수 있음을 시사한다.

The result of variance decomposition through yield of Treasury of 30 year maturity of USA, S&P 500 index, stock price of KEPCO has 76.12% of impulse of KEPCO stock price at short-term horizon, but they have 51.40% at long-term horizon. After one year, they occupy 13.65%, and 33.25%. So their effects are increased. By the way, S&P 500 index and yield of Treasury of 30 year maturity of USA have relatively more effect for forecast of stock price oi KEPCO at short-term & long-term. The yield of Treasury of 30 year maturity of USA more than S&P 500 index have more effect for stock price of KEPCO. It is why. That foreign investors through fall of stock price of USA invest for emerging market is less than movement for emerging market of hedge funds through effect of fall of yield of Treasury of 30 year maturity of USA, according to relative effects for stock price of Korea companies. The result of variance decomposition through won/dollar foreign exchange rate, yield of corporate bond of 3 year maturity, Korea Stock Price index(KOSPI), stock price of KEPCO has 81.33% of impulse of KEPCO stock price at short-term horizon, but they have 41.73% at long-term horizon. After one year, they occupy 23.57% and 34.70%. So their effects are increased. By the way, KOSPI and won/dollar foreign exchange rate have relatively more effect for forecast of stock price of KEPCO at short-term & long-term. The won/dollar foreign exchange rate more than KOSPI have more effect for stock price of KEPCO. It is why. The recovery of economic condition through improvement of company revenue causes of rising of KOSPI. But, if persistence of low interest rate continues, fall of won/dollar foreign exchange rate will be more aggravated. And it will give positive effect for stock price of KEPCO. This gives more positive effect at two main reason. Firstly, through fall of won/dollar foreign exchange rate and rising of credit rating of Korea will be followed. Therefore, foreign investors will invest more funds to Korea. Secondly, inflow of foreign investment funds through profit of won/dollar foreign exchange rate and stock investment will be occurred. If appreciation of won against dollar is forecasted, foreign investors will buy won. Through this won, investors will do investment. Won/dollar foreign exchange rate is affected through external factors of yen/dollar foreign exchange rate, etc. Therefore, the exclusion of instable factors for foreign investors through rising of credit rating of Korea is necessary things.

주관적 행복이 각광 받고 있다. 주관적 행복에 따라 사회비교 및 인지부조화 해소가 달라지는 것처럼, 주관적 행복이 소비자의 대안 비교와 평가에 영향을 미칠 것이다. 본 연구는 소비자가 선택한 혹은 선택하지 않은 대안에 대한 추가 정보로 인해 대안의 절대적 가치 및 상대적 가치가 변동할 때, 대안에 대한 평가가 소비자의 주관적 행복에 따라 어떻게 달라지는지 연구하는 것을 목적으로 하였다. 특히, 소비자가 제품에 대해 지각하는 가치를 반영하는 소비자가 생각하는 대안의 적정가격을 사용하여 대안에 대한 평가를 측정하였다. 즉, 선택 혹은 비선택 대안의 상대적 가치 및 절대적 가치의 변화가 대안의 적정가격에 미치는 영향이 주관적 행복에 따라 달라지는지 살펴보고자 하였다. 연구를 위하여 98명의 대학생을 대상으로 실험을 실시하였다. 먼저, 학생들을 두 집단(비선택 대안 악화, 선택 대안 개선)에 무작위 할당한 후, 실험실 모니터에 2개의 대안에 대한 소비자 리포트를 제시하였다. 학생들이 하나의 대안을 선택하면, 대안에 대한 소비자 리포트의 평가가 변동(비선택 대안 악화, 선택 대안 개선)하면서 비선택 대안의 가격이 주어지고, 학생들은 선택 대안의 적정가격을 답하였다. 2주 후 학생들의 주관적 행복을 설문지로 측정하였다. 연구 결과, 집단, 주관적 행복의 단순효과 및 이 둘의 상호작용효과가 유의하였다. 또한, 행복한 사람은 비선택 대안이 악화될 때 보다 선택 대안이 좋아질 때 선택 대안의 적정가격을 높게 평가한 반면, 불행한 사람은 이러한 차이가 없었다. 이는 행복한 사람은 선택 대안의 절대적 가치 상승에 민감한 반면, 불행한 사람은 선택 대안의 절대적, 상대적 가치 상승 모두에 민감하며, 불행한 사람은 행복한 사람보다 비선택 대안의 악화 정보에 집중함을 의미한다. 본 연구는 소비자의 주관적 행복이 대안 평가에 미치는 영향을 제시함으로써 기존 연구를 확장하였다. 특히, 타인의 존재가 명시되지 않은 상황에서도 행복한 사람보다 불행한 사람이 부정적인 사회비교 정보에 민감함을 보였다는 점에서 이론적 의의가 있다. 아울러, 이러한 결과는 소비자의 주관적 행복 수준에 따라 대안을 어떻게 제시해야 하는지에 대한 시사점을 유통업체들에 제공한다. 본 연구는 한국의 소비자를 대상으로 진행하였으나, 향후 연구에서 국가간 차이를 비교하는 것도 의미 있을 것이다. 또한, 주관적 행복이 대안 평가에 미치는 영향의 메커니즘을 밝히기 위하여 예상되는 후회감, 고통, 기쁨 등을 매개변수로 놓고 추가 연구를 진행할 필요가 있다.

This study suggests the dynamic pricing model which reveals the organic relationship between ASP (Application Service Provider) price and the related factors, using system dynamics methodology. Basically, we applied the law of supply and demand for analyzing price changes. Then, we deducted ASP price, focusing on fixed cost and variable cost. We also researched the customer's buying behavior according to version differentiation policy. In the version policy, we set up the proposition about customer's satisfaction and willingness-to-pay, using option system. As a result, this research designed the simulation model which analyzes the changes of the sales according to version differentiations and customer's willingness-to-pay. Through this research, we can find effective version differentiation strategies. This paper also found that the larger the number of package, the greater the demand and customer's willingness-to-pay. The increase of the number of package causes the increase of the sales. The increase of the sale is not exactly relative to the number of package. Drawing S-curve, the sales was increased. This dynamic pricing model suggests the ground that the ASP price changes based on the existing version differentiation theory and the demand of customers can affect the changes of the sales. We expect that this model suggests a clear standard of ASP pricing by combining real cases.

Although South Korea experienced a rolling blackout in 2011, the possibility of a blackout in South Korea continues to increase due to rapid electrification. This study examines the problems of energy taxation and price distortions as possible reasons for the rapid electrification in South Korea, which is occurring at a faster rate than in Japan, Europe, and other developed countries. Further, we suggest new energy taxation and price systems designed to normalize electricity prices. In order to do so, we consider two possible scenarios: the first imposes a tax on bituminous coal for electricity generation and the second levies a tax to provide compensation for the potential damages from a nuclear accident. Based on these scenarios, we analyze the effects of a new energy system on electricity price and demand. The results show that a new energy system could guarantee the power generation costs and balance the relative prices between energy sources, and could also help prevent rapid electrification. Therefore, the suggested new energy system is expected to be utilized as a basis for energy policy to decrease the speed of electrification, thus preventing a blackout, and to induce the rational consumption of energy in South Korea.

The purpose of this study was to identify tourist product factor combinations which confer the highest utility to tourists and to establish the relative importance of factors in terms of their contribution to total utility across gender. Among 250 questionnaires, 230 questionnaires were utilized for the analysis. $X^2$ analysis, Conjoint model, Max. Utility model, BTL model, Logit model, K-means cluster analysis, and one-way anova analysis were used for this study. The findings from this study were as follows. First, the Pearson's R and Kendall's tau statistics showed that the model fitted the data well across gender. Second, it was found that total respondents and three clusters regarded taste price as the very important factor across gender. Third, it was found that the male and female tourists most preferred product with light red color, shaped package, and highly pungent taste sold at a cheap price in factory. Fourth, it was found that the male tourists most preferred simulation product with light red color, shaped package, and highly pungent taste sold at a cheap price in factory. The female tourists most preferred simulation product with light red color, shaped package, and mild taste sold at a cheap price in factory. Finally, the results of the study provide some insights into the types of effective product designs that can be successfully developed by marketers.

The business market of architecture has got a system that controls a deposit according to the price function. This system is written on a law of contract about countries. So the main body of construction has to make a reasonable contract. This study is written about a rate of numerical index on controling a deposit. We tried to fine problems and solutions of labor expenses, instrument costs and material costs which is so big and changable on the construction market Labor expenses are expressed according to the rate of construction scale between direct and indirect cost that applies ability of works. Instrument costs are expressed according to an output method of a unit price annually and a weight allowance of local instrument conditions and use frequence. The last material costs expressed according to a local weight allowance make a decision of the material cost index. They applies locally relative index more than absolute one on what uses the price rate of producers and importations. This solutions are not enough to apply to the real market, so it needs to exam and to be on the market after a feasibility study.

Purpose - We investigate how firms transfer financial risks to employees in a form of flexible employment contracts and layoffs. Design/methodology/approach - Based on the literature on the prevalence of shareholder value ideology and the associated 'risk shift', we examined how stock price volatility is associated with a firm's use and hiring of nonstandard employees, and the number of employees lay-offed. We test our hypotheses using a longitudinal, multi-source, dataset of Korean firms from 2003 to 2011. Findings - We found support for the relationship between stock price volatility and flexible employment contracts and layoffs after controlling for actual risks such as increased debt or decreased sales. However, we found that the relationship is moderated by the power of professional CEOs relative to that of shareholders, in that powerful CEOs are more likely to transfer the external risks, i.e. stock price volatility, to employees. Research implications or Originality - This study contributes the emerging stream of literature that explore the effect of stock market pressures and governance structures on human resource management.
