본 연구는 국제 원유가격의 변동에 따른 수송용 유류제품 가격의 비대칭성(rockets and feather)을 오차수정모형을 사용하여 분석한다. 회귀분석결과에 따르면, 모든 수송용 유류제품에서 비대칭성 현상이 일관성 있게 나타났으며, 특히 고급휘발유에서는 타 유종에 비해서 비용 상승기와 비용 하강기에 모두에서 비용의 변화의 충격에 민감하게 반응하는 것으로 추정되었다. 이는 비용상승기의 경우, 마진이 높은 고급휘발유의 특성상, 이를 빠르게 반영하는 것은 이윤극대화를 추구하는 기업의 합리적인 반응일 것으로 추정된다. 그러나 비용이 하락할 경우에 고급휘발유가 타 유종에 비해서 빠르게 하락하는 현상은, 고급휘발유 가격이 상승할 때, 일반휘발유로 이동했던 소비자들과 고급휘발유에 대한 잠재적 수요를 가진 일반 휘발유 소비자들을 고급휘발유 소비로 끌어들일 수 있는 유인이 존재하기 때문으로 판단된다.

Purpose: The revenue sharing contract has been used in various industries and it is expected to coordinate the individual companies' operations in a way to improve the whole supply chain performance. This study evaluates the performance of the revenue sharing contract to find out whether this contract achieves its original goal, the supply chain coordination. Research design, data, and methodology: The profit optimization models are developed to represent two stage supply chain system with a supplier and a buyer. By using the numerical examples of the proposed mathematical models, this study examines whether this supply chain contract coordinates the supply chain system. Results: The numerical examples show that the revenue sharing contract does not make the same supply chain profit as the centralized system does. With the proper combination of the wholesale price discount rate and revenue share ratio, both manufacturer and retailer can obtain increased profits from the revenue sharing contract. Conclusions: The outcomes of the numerical analysis imply that the revenue sharing certainly improves the supply chain performance but it does not fully coordinate the supply chain system. By controlling the wholesale price and revenue share ratio, every supply chain member can be beneficiaries of this supply chain contract.

This research investigates the supply chain contract between a distributor and a supplier in which the selling period is relatively short in comparison with long production lead time. At the first stage, supplier who is a Stackelberg leader offers the distributor a contract with a set of parameters, and subjected to those parameters, the distributor places the number of initial orders as well as options. In order to purchase the option, the distributor pays non-linear option premium price with respect to the number of purchased options. At the second stage, based on realized demand, the distributor has the right to exercise option as either put or call which is limited up to the number of purchased options. The wholesale price contract is used as a benchmarking contract. This research has confirmed that the supply chain contract with a non-linear option premium price can help to coordinate the supply chain.

Three varieties of green pepper - Chungyang pepper, Cucumber-taste pepper and Nokgwang pepper - are competing with one another in consumption due to the overlapping shipment period. The objective of this study is to analyze the influence of monthly variations of shipment quantities on the wholesale market prices. A Linear Approximated Inverse Almost Ideal Demand System (LA/IAIDS) is employed with monthly data set of three different varieties of green pepper consumption. The results show that if there is an excess supply in the market, the rate of the price decline is larger for forcing culture Chungyang pepper than other pepper varieties. On the contrary, change in supply of cucumber-taste pepper and Nokgwang pepper has little effect on the price of Chungyang pepper. The results of this study can be utilized as a basic information for enhancing the farm income and promoting agricultural policies related to the establishment of self-help funds by Chungyang pepper producer groups in Gyeongnam region.

Fisheries products in Korea generally go through three markets, namely the wholesale market at production site (Market A), the wholesale market at consumption site (Market B), and the retail market (Market C), from producers to end consumers. As the products move from Market A through Market B to Market C, the marginal gap of prices asked in these markets demonstrates an apparent relationship. The producers, middlemen, consumers, and governmental departments concerned may influence the marketing prices of fisheries products. This study employing the cointegration theory tries to investigate whether causality of the price-setting among these markets exists and, if any, what it is. The authors have focused their attention on fisheries markets in Pusan, analyzing the long-run equilibrium relationship and causality between the prices of hairtail and squid among markets at different levels. Data used in this study cover the period f개m August 1984 to December 1997 fer hairtail, and the period from May 1989 to December 1997 for squid. The main findings of the study may be summarized as follows: First, regardless of the price time-series of hairtail and squid in individual market, the first difference is necessary fur satisfying the stationary conditions since each time-series is a first integration. This means homogeneous integration of time-series, which is a requirement of the long-run equilibrium of prices at different markets, is satisfied. Second, the study of the long-run equilibrium relationship between the prices at Market A and Market B shows that a long-run equilibrium relationship does exist for selling prices of the two species at Market A and Market B. Third, the ECM (error correction model ) used here to describe the long- and short-run dynamics of price change demonstrates that, in the case of squid, the price change in Market A will lead to a corresponding price change in Market B in the long-run period. In the short-run, however, the price at Market H is not only influenced by the price change in Market A but influence the price at Market A as well, that is, the Prices between Market A and Market B have a feedback effect. It should be stressed that the limitation in data collection, which cover only two species of hairtail and squid, is likely to cause a sampling bias. Nonetheless, we may conclude that a dynamic relation in the formation of prices does exist in view of the transaction amount of species at different markets. It is believed that the conclusion drawn from this study would not only contribute to a long-lasted debate on the direction of causality of price-setting among academic circle and fishing community, but would provide a useful standard for the policy makers in charge of the price-setting of fisheries products as well.

Since organized living cooperative associations sold their environment-friendly agricultural products directly to independent consumers in the past, the general distribution channels such as wholesalers had difficulty in handling these products. However, the ratio of distribution via wholesale channel has been gradually increased as consumption of environment-friendly agricultural products has expanded. This study is to address vitalization of wholesale distribution for environment-friendly agricultural products by gathering previous statistical data and analysis. In addition, statistical analysis are conducted by utilizing surveys on forwarders, consumers for environment-friendly agricultural products. As a result, the products producers ship are distributed through dealers at producers sites, producers cooperatives, or food process companies, food companies, internet shopping malls, large-scale distribution companies, consumer groups such as living cooperative associations, direct outlets at consumers sites, or exports. Among the channels, the large-scale distribution companies and franchised special shops account for 47%, the general supermarkets 15.7%, and living cooperative associations 14.6% respectively. By utilizing the research results on producers and consumers, and the distribution weight by channels for environment-friendly agricultural products, the distribution channels for living cooperative associations, wholesale markets, and large scale distribution companies are compared and evaluated. As a result, the level of producers' and consumers' satisfaction for them is the lowest since the low selling price for producers and high distribution margins.

This study examines the dynamic linkages between food price inflation and its volatility in the context of Sri Lanka. The empirical evidence derived from the monthly data for the period from 2003M1 to 2017M12 for Sri Lanka. The relationship between inflation rate and inflation volatility has attracted more attention by theoretical and empirical macroeconomists. Empirical studies on the relationship between food inflation and food inflation variability is scarce in the literature. Food price inflation is defined as log difference of food price series. The volatility of a food price inflation is measured by conditional variance generated by the FIGARCH model. Preliminary analysis showed that food inflation is stationary series. Granger causality test reveals that food inflation seems to exert positive impact on inflation variability. We find no evidence for inflation uncertainty affecting food inflation rates. Hence, the findings of the study supports the Friedman-Ball hypothesis in both cases of consumer food price inflation and wholesale food price inflation. This implies that past information on food inflation can help improve the one-step-ahead prediction of food inflation variability but not vice versa. Our results have some important policy implications for the design of monetary policy, food policy thereby promoting macroeconomic stability.

한 가지의 용량가격만으로는 발전용량 설비투자에 대한 안정적 보상과 시장 기능 유지라는 두 가지 목표를 동시에 달성하기 힘들다. 본 논문은 이런 한계를 극복할 수 있도록 복수의 용량가격을 도입하여 용량가격의 비중을 높이면서 동시에 시장 기능을 유지할 수 있는 이원적 용량가격 제도를 제안한다. 즉, 현재 가스터빈 발전기를 기준으로 하면서 행정적으로 결정되는 용량가격을 그대로 유지하면서, 동시에 LNG복합발전기를 대상으로 한 제2의 용량가격을 도입한다. 이 용량요금은 더 낮은 에너지 가격 상한의 적용을 받으며, 상이한 전원들 사이의 대체관계를 고려한 수요와 용량공급 상황을 반영하도록 설계함으로써 시장 기능을 유지하게 한다.
