This study investigates the effects of changes in price, total consumption expenditures and economic sitations on Korean household demands for clothing and footwear using time-series data. The clothing and footwear category was reclassified as clothing, footwear and clothing services items for the demand analysis. This study utilized the Linearized Almost Ideal Demand System (LAIDS) model to analyze household demand. The results indicate that price and total consumption expenditures are significantly related to Korean household consumption expenditure allocations for clothing and footwear items. The effects of the IMF bailout crisis in 1997 and the global financial crisis in 2008 on household expenditure shares for clothing and footwear items were very weak and statistically insignificant. All the demand elasticities were estimated with respect to total consumption expenditures and prices. Clothing was expenditure elastic (greater than one) and other items were classified as inelastic. All the own price elasticities of demands were negative (other than clothing). Through the estimations of cross price elasticity the relationships between the demands for items and other item prices were evaluated (i.e., substitutes and complements).

묶음제품의 매력도를 증가시키기 위해 소비자들이 번들 오퍼에서의 가격 제시 프레이밍(framing)에 민감하다는 것을 이해할 필요가 있다. 동일 가격을 할인하더라도 묶음제품 요소 중 어느 요소에 가격할인을 표시하느냐에 따라 소비자의 묶음제품에 대한 지각된 매력도를 바꿀 수 있기 때문이다. 선행연구는 더 중요한 제품 요소에 할인이 할당될 때 효용이 증가한다는 주장과 덜 중요한 제품 요소에 할인을 위치시키는 것이 선호를 증가시킨다는 주장을 동시에 보이고 있다. 본 연구는 선행연구를 보완하여 묶음제품 가격 할인 제시 프레이밍효과에 대한 새로운 기제를 제시한다. 그리고 선행연구에서 믹스드(mixed)된 결론을 보이는 이유를 분석하여 밝힌다. 본 연구는 현실적인 번들링 전략 사용 상황을 고려하였으며, 좀 더 리얼한 번들링 세팅을 이용하여 가격 할인 제시 프레이밍 효과를 조사하고, 순수번들 및 혼합번들을 포함한 다양한 묶음제품을 이용하여 품질 불확실성 지각에 따른 조절효과를 분석하였다. 본 연구 결과, 소비자들은 높은 소비 혜택(high consumption benefit)보다 낮은 소비 혜택(low consumption benefit) 요소에 가격 할인을 위치시키는 것을 더 선호하였다. 가격민감성(price sensitivity)이 주요혜택에서는 낮고, 낮은 혜택에서는 높기 때문에 동일 가격이 할인될 때 낮은 혜택을 할인한 매장 제품에 대한 평가가 더 높게 나타났다. 또한 구매 시점에서 품질의 불확실성(perceived uncertainty of product quality)이 높을수록 가격민감성이 혜택 지각에 가지는 효과가 더 커지고 있었다. 본 연구의 공헌은 소비 혜택 지각 및 가격민감성 기제와 지각된 품질 불확실성의 조절효과를 통해 선행연구를 통합하고, 가격 제시 형태의 프레이밍 효과를 명확하게 설명하였다는 점이다.

Supply chain management (SCM) has been regarded as one of the most critical issues in the current business environment. Moreover, supply chain partnerships between suppliers and buyers in SCM have had a significant impact on supply chain performance. In this paper, we conduct a quantitative analysis for supplier-buyer's profit sharing and pricing policies based on supply chain partnerships. For this purpose, we assume that a two echelon supply chain with a single supplier and a single buyer is given and the buyer faces deterministic demand which is not only a function of buyer's selling price, but also strictly decreasing, concave, and twice differentiable function. Then we will prove the following. Firstly, without supply chain partnerships, there exist supplier and buyer's selling prices per unit such that their total profits are maximized, under the assumption that buyer's order quantity is exactly equal to the demand buyer faced. Secondly, buyer's selling price per unit which maximizes supply chain's total profit with supply chain partnerships is lower than buyer's selling price per unit which maximizes buyer's total profit without supply chain partnerships. Thirdly, given supplier's selling price per unit. buyer's total profit without supply chain part nerships is greater than that with supply chain partnerships, whereas the opposite case happens for supplier's total profit. Finally, there exists supplier's selling price per unit which makes the maximum total profits for both supplier and buyer with supply chain partnerships greater than those obtained for any given supplier's selling price per unit without supply chain partnerships.

Customers hardly change to electric prices in old days because electricity is essential commodity, while demand changes with price after deregulation. It's explained by price-based demand response with demand-elasticity matrix. Also all of the customers have had identical demand-price elasticity matrix till now. But in a practical power system, various customers are present with taking a variety of demand-price elasticity. Therefore this paper proposes demand-price sensitivity to represent different demand-price elasticity. Also as proposing demand-reliability sensitivity, it is modeling various customers' characteristics to reliability. And then this paper calculates total expected interruption cost of customer from the customer interruption cost and the demand-reliability sensitivity. A total expected interruption cost of system is shown as opportunity cost of a generation cost.

We investigate a practical method of calculating the impact of multiple domestic energy price change on the final demand, production, the export and import change, the change in the balance of payment of Korean economy. By combining an existing computable general equilibrium (CGE) model with the traditional input-output analysis with two additional assumptions on the price behavior, we provide a cost-effective method of analyzing the impact of multiple energy price changes on the domestic economy. The energy price shock we used in this paper is 0.127% increase weighted by the sectoral productions. The total impacts on price level and GDP are 1.258% and -0.940%, respectively. The impact on the total output (GDP and intermediate goods) is about -1.580%.

Recent trend of ginseng (p. ginseng) trade in Japan was analyzed. From 1984 white ginseng import increased continuously to 240% while export of red ginseng decreased to 29%. Red ginseng import increased until 1990 and decreased thereafter, resulting in 12% of total import ginseng in 1993 from 47% in 1990. During five years (1989∼1993) white ginseng import from Korea decreased from 44% to 14% of total white ginseng imported while import from China increased. Red ginseng import from China ranged 97 to l00% of total red ginseng and little change was shown during five years. Price of Korean ginseng was higher than that of China by 2.2 times for white and 6.6 times for red. The continuous decrease of Chinese ginseng price might affect import trend. Export price of red ginseng increased continuously and was higher than that of Korean red ginseng (1.95 times) and much higher than import price (20 times in 1993).

본 연구는 무의결권 우선주와 보통주간의 주가괴리율의 실태와 아울러 주가괴리율에 영향을 미치는 요인에 대해 알아보고자 하였다. 이를 위하여 국내 증권거래소에 상장된 106개 기업 우선주를 대상으로 2006년 1월부터 2008년 12월말까지 우선주와 보통주간의 주가괴리율이 나타나는 결정요인에 대해 분석하였다. 본 연구의 분석결과를 종합하면 다음과 같다. 첫째, 유보율의 경우 대체로 유의수준 5%하에서 유의하나 예상과는 달리 주가괴리율과는 정반대의 관계를 갖는 것으로 나타났다. 둘째, 자본금 변수는 대체로 유의수준 1% 하에서 유의한 것으로 나타났다. 셋째, 우선주 발행비중은 모든 모형에 걸쳐 유의수준 5% 하에서 유의적인 것으로 나타났다. 넷째, 매매회전율은 평균 주가괴리율을 종속변수로 한 모든 모형에서 유의수준 5%하에서 유의한 것으로 나타났다. 최근의 주가괴리율은 기업규모와 우선주의 발행비중, 그리고 매매회전율에 의해 설명되는 측면이 많다고 볼 수 있다. 특히 우선주의 발행비중은 그 영향력이 가장 클 뿐 아니라 일관된 유의성을 보이고 있어 발행비중의 조절을 통해 주가괴리율이 어느 정도 해소될 수 있는 가능성을 시사하고 있다.

Korean health insurance has adopted preliminary DRG payment system through 8 DRGs from 1997. But present DRG payment system gives economic incentives for hospitals to hire less nurse. This study was attempted to develope DRG adjust index to differentiate DRG price by nurse staffing level for nursing care quality. Method: We analyzed inpatient care cost by medical institute and developed DRG adjust index to differentiate DRG price by nurse staffing level. Results: Among same medical institute, inpatient care cost are very different according to hospital's nurse staffing level. In the case of casarean section, inpatient care cost of the 1st grade general hospital are more expensive 85,732won than the 6th grade hospital. The cost difference are 8.24% of total casarean section DRG price and 16.48% of DTG variable price. We developed DRG adjust index-a to apply DRG variable price and index-b to apply DRG total price for compensation cost difference of hospitals. Conclusions: DRG price adjust index will give economic incentive for hospitals to hire more nurse and improve nursing care quality.

This paper presents a coordinated planning model of price-dependent demand for a single-manufacturer and a single-retailer. The demand is assumed to be normally distributed, with its mean being price dependent. The manufacturer and retailer coordinate with each other to jointly and simultaneously determine the retail selling price and the retailer order quantity to maximize the joint expected total profit. This model is then compared to a 'returns' policy model where manufacturer buys back unsold items from the retailers. It is shown that the optimal total profit is higher for coordinated planning model than that for the returns policy model, in which the retail price is set by the retailer. A compensation or profit sharing scheme is then suggested and it is shown that the coordinated model with profit sharing yields a 'win-win' situation. Numerical results are presented to illustrate the profit patterns for both linear and nonlinear demand functions. The coordinated planning model, in addition, has a lower optimal price than for a returns policy model, which would result in higher sales, thus expanding the markets for the whole supply chain.

Purpose: This research investigates whether the existence of preannouncing price discount before purchase has an effect on after regret about purchasing and price fairness perception. Moreover, this paper examines whether the preannouncing effects on regret (or price fairness perception) are moderated by motive inference type (or brand trust). Research design, data and methodology: This experimental design consisted of total 8 between-subjects full factorial, which is completed by 2 (preannouncing price discount before purchase) × 2 (motive inference type) × 2 (consumer's brand trust level). Results: First, regret (or price fairness) differs depending on the presence/absence of preannouncing price discount before purchase and price discount motive inference type. Second, interaction effect of preannouncing price discount presence/absence before purchase and price discount motive inference type on regret (or price fairness) after purchase differs depending on motive inference type (or brand trust). Conclusions: Preannouncing external cue could decrease the possibility of consumers to regret and prevent consumers perceiving price change as unfair. Thus, corporations should sufficiently explain to consumers about preannouncing and specific reason of price fall in order to decrease regret caused by price fall and to increase price fairness perception from preannouncing effect.
