This paper estimates the price of standard waste bags that satisfies the polluter pays principle. Unlike previous studies, this paper suggests a method that can find new equilibrium prices using a structural relationship between the demand and cost function for the wastes. To do this, we employ the fixed-point iteration. The main findings of this paper are as follows. Assuming that the polluter pays principle is achieved at the average cost for the waste treatment, the price need to be set at a level about 3.12 times higher than the current one. The estimation result using a structural model, however, shows that the price should be set at a level four times higher than the present. This results are because the quantities reduced of the wastes make the cost per quantity of wastes due to the fixed costs increase. If applying the estimated price to the demand function, the amount of discharge of waste generated nationwide can be reduced by 10%.

This paper aims to analyze characteristic by the cities focused on the ratio of new apartment resale that is one of the apartment unit sale market, which has been increased recently. So, this study examined characteristics of population, apartment trade & sale, housing with 162 cities and counties and performed multiple regression analysis with dependent variable, ratio of new apartment resale. As a result. the factors affecting the ratio of new apartment resale are 7variables, apartment sales rate, transfer of ownership, apartment turnover rate, sale volume, regional apartment rate, population increasing rate, housing average apartment sale price rate. In terms of the increase in apartment sales prices, the rate of sales price increase was relatively low in areas where the transaction rate for apartment sales is high, and the number of apartment sales right transactions increased as the number of other ownership transfers rose. As a result, the data will be based on the improvement of the government's policies and systems to stimulate the transaction focused on the real estate agents in the apartment market.

This paper examines the effects of prior industry experience, new product attributes and online customer review on new product sales. Different from prior researches on the volume and valence of customer review on online shopping, this paper investigated multiple factors on new product sales in online shopping mall. Based on 407 TV new products in China online shopping mall, we investigated the relationships of kew factors with new products sales. New products of Incumbent TV manufacturers outsell those of new entrants in TV market. Low initial price and low level of discount rate have positive relationships with new product sales. Technological superiority has positive effect on new product sales but the adoptions of new technological functions show different effects on sales. The volume of online consumer review also has positive relationship with new product sales. This paper suggest some theoretical and practical implications and future research directions.

This Research focuses on the effect of the price limits change in KOSDAQ market change on the volatility. The sample period ranges from 22 May 2000 to 24 March 2010 for daily data. We construct two subsample periods for comparing with the effect of the change of the price limit. These limits were relaxed from 12% to 15% on March 25, 2005. The first subsample period is from 25 March 2000 to 24 March 2005. The second subsample period is from 25 March 2005. to 24 March 2010. We employee four different volatility, which are the range-based volatility of Parkinson(1980; PK), Garman and Klass(1980; GK) Rogers and Satchell(1991; RS), Yang and Zhang(2008; YZ). The empirical result as follows. The major findings are summarized as follows; First, the volatility of individual stocks in KOSDAQ market reduces significantly after the price limit change. Second, There is so high volatile especially when the volatility of stock prices is high. Third, There is no meaningful relationship between volatility and market capitalization. Fourth, the more volume stocks reduce the volatility. Our results show the volatility decreased the more large volume, the more trading amount and the high price stock.

We have seen a sharp increase in the utilization rate of medical services since the launch of Nation Health Insurance system in 1989. However, the market share of oriental medicine in the Korean health sector has been gradually diminished mainly due to low insurance coverage and high price. Especially high price as an entry barrier to oriental medical services has played a major role in decreasing market share. This paper investigated the effects of price discount on the financial condition and market share of oriental medical institutions. Microeconomic theory and multiple regression analysis were used as a methodology in testing the alternative hypothesis: price discount of enveloped herb drug will result in increases in both the revenue and market share of oriental medical institutions. Data was collected from the statistical yearbook and sample survey. The price elasticity of demand for enveloped herb drug was estimated at 5.8 during 1987-1995 period, which means that a 1% decrease in price will bring about a 5.8% increase in the utilization of oriental medical services. The empirical result shows that a drastic price discount for the enveloped herb drug will eventually improve the financial status of the oriental medical institutions and enlarge the market share of oriental medicine in the Korean health care sector.

This study estimated the long-run and the short-run price and income elasticity of crude oil demand by using the ARDL model in Korea. First, the long-run cointegration relationship existed between crude oil demand and price or income in the ARDL-bounds tests. Second, the long-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL. Third, there was autocorrelation of the residuals, but no misspecification errors and heteroscedasticity, and then the residuals showed a normal distribution. And the CUSUM & CUSUMSQ tests showed that the coefficients were stable. Fourth, the short-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL-RECM. The ECM with the short-run dynamics showed rapid adjustments in the long-run equilibrium of oil demand after the economic crisis. In the short-run, the sensitivity of crude oil demand to price and income changes has moved in the same direction as the long-run case. Korea, depending too much on foreign crude oil, is vulnerable to the shocks of oil prices, so rising oil prices can certainly have a negative impact on Korea's trade balance. And the elasticity of long-run oil prices may help to control and manage Korea's oil demand. The government needs to strengthen monitoring of the country's policies and market trends related to crude oil, establish strategies to customize national policies and market conditions, and strengthen active market dominance efforts through pioneering new market and diversification.

While new evidence on international spillover effects has been widely discussed around the globe, the MENA (Middle East and North African) region has received little attention concerning international transmission of stock market movements. In this paper, we discuss international spillover effects between the major developed markets (US, Japan and Germany) and the emerging markets in the MENA region (Turkey and Egypt). While GARCH-type models have mainly been used to investigate international stock market spillovers in much of previous studies, we develop new testing strategies based on discrete wavelet decomposition. The basic finding is that price as well as volatility spillover effects exist from the developed stock markets to the MENA counterparts, although evidence for price spillover to the Egyptian market is rather weak. As for the interdependence of the major MENA stock markets, no spillover effects are found between these markets, while the two MENA markets are somewhat related with each other.

성장세를 보이던 출력업체가 IMF 이후 과당경쟁과 더불어 기자재 수입원가의 증가로 인해 수입구조에 많은 변화를 가져오면서 경영난에 봉착한 가운데 서체회사의 횡포아닌 횡포(?)에 몸살을 앓고 있는 회사가 늘어나고 있다. 서체가격은 IMF 이전에 비해 점차 낮아지고 있는 경향은 있으나 새로운 서체의 개발이나 A/S 문제, 중고 장비와 관련된 서체의 문제 등 여러 요인으로 인해 출력업체는 많은 어려움을 겪고 있다. 서체라는 것은 일반 소비용품과는 달리 대체재가 있거나 싫다고 쓰지 않으면 되는 것이 아니라 각각의 회사에서 출시한 서체를 다 사용할 수밖에 없는 구조로 이루어져 있어 슈퍼마켓처럼 온갖 제품들을 다 갖추고 있어야 한다. 그래서 출력업체는 싫든 좋든 울며 겨자 먹기 식으로 각종 서체를 갖추어야 하고 새로운 서체가 출시될 때마다 업그레이드 해야하는 고충을 안고 있다. 이 뿐만이 아니라 A/S도 돈을 주면서도 눈치를 봐야 하는 입장이어서 고객이 왕이 아닌 메이커가 왕인 세상이 되어버린 것이다. 출력업체와 서체회사는 상호 협력적인 관계에 있으면서 실상은 서체회사가 주도해 나가는 형국이고 출력업체는 끌려가는 입장이 되었다. 서체회사는 나름대로의 입장과 고충이 있겠지만 출력업체는 일방적인 서체회사의 횡포에 가까운 행위에 대해 이렇다 할 입장표명도 하지 못하고 속앓이만 하고 있는 실정이다. 서체와 관련된 출력업체의 의견을 정리해 보았다.

본 연구의 목적은 공적분 검정과 예측오차 분산분해 방법을 이용하여 우리나라 주식시장에서 주가지수와 거시경제 변수들과의 계량적 관계를 파악하고 종합주가지수와 밀접한 관련성이 있는 변수를 사용하여 종합주가지수와 거시경제변수들 사이의 모형을 추정하는 것이다. Johansen 공적분 검증을 이용한 결과를 보면 종합주가지수와 7개의 거시경제변수들(총통화, 소비자물가지수, 금리, 산업생산지수, 원 달러 환율, 국제원유가격, 경상수지) 사이에 상당히 밀접한 연관성이 있으며, 이들 변수들 사이에 장기적 균형 관계가 존재하였다. 예측오차 분산분해 방법을 사용한 분석결과에서는 종합주가지수의 분산을 예측하는데 있어서 이들 거시경제변수들의 설명력이 매우 높게 나타났다. 또한 우리나라의 주식시장에서는 금리, 국제원유가격, 경상수지 등의 요인보다는 원 달러 환율, 소비자물가지수, 산업생산의 비중이 더 크다는 사실을 알 수 있었다. 우리나라의 자본시장에서는 1997년 말 외환위기를 전후로 하여 현저한 구조적 변화가 존재하였기 때문에 백터오차수정모형을 설정할 때에는 외환위기 이전기간과 이후기간으로 나누어서 분석하는 것이 더욱 타당함을 확인할 수 있었다.

우리 면방산업은 1994년도의 일시적인 회복을 제외하고는 극심한 노사분규가 있었던 87년 이후부터 3저 현상의 퇴조와 함께 지속적인 경기부진에서 벗어나지 못하고 있는 실정이다. 1994년 말부터 제조원가의 약 60%를 차지하는 원면가의 상승은 1995년 상반기 파운드당 1달러의 폭등여파로 인해 1996년도 생산라인에 투입된 원면의 가격이 거의 90센트를 넘어 생산원가를 크게 상승시켰다. 게다가 면사 등 제품가격은 오히려 하락 또는 정체를 면치 못해 1996년도에는 많은 면방회사들이 적자를 기록하였다. 이러한 어려움에 직면한 한국 면방산업은 설비 노후화. 고임금, 심각한 인력부족 등의 당면과제에 실마리를 찾지 못하고 있으며, 후발개도국의 추격에 따른 한국의 국제시장 점유율 하락 및 수입의 급증으로 인한 대외경쟁력 저하로 만성적인 불황의 늪을 벗어나지 못하고 있다. 한편 업계에서는 부득이한 조치로서 방적설비를 해외로 이전시켜 해외생산을 계속 확대 추진하고 있는 실정이다. 다음은 한국 면방산업에 대한 개괄적 자료이다.
