Purpose - This study investigates the lead-lag relations between the prices of major commodities imported into Korea and corresponding shipping freight rates. This paper aims to provide implications for cross-market causal relations between related economic segments. Design/Methodology - For economic long-run equilibrium between commodity prices and freights, a Johansen (1988) cointegration test is employed first. Then, Granger (1987) causality tests are performed under the vector error correction model (VECM) framework. Findings - The results indicate that the direction of causality varies by raw materials, which is attributable to different economic mechanisms in the corresponding shipping transportation sectors. In addition, the significance of causality becomes blurred during the post-2008 period. Practical Implication - Corporate managers in commodity trading, steelmaking, power generation, and oil refinery sectors can take advantage of the findings in this study as identifying leading economic indicators can be helpful for decision making in both short- and long-term strategies. Originality/value - This study is the first attempt to analyze the inter-relations between commodity prices and corresponding freight rates focusing on raw material imports of Korea.

소비 자본주의는 상품 물신화 전략을 통해 상품에 내재되어 있는 실재적인 지리적 지식을 상상적인 지리적 지식으로 대체시켜 나간다. 이로 인해 현대의 소비자 세계 속에서 학생들은 상품의 실재 세계와 단절되고 상품이 가지는 지리적 삶을 망각하게 됨으로써 결국 자신과 상품을 관계적으로 사고 할 수 있는 능력이 약화되고 있다. 그래서 학생들은 상품의 글로벌 네트워크 속에서 자신이 가지는 위치의 의미와 자신과 상품 네트워크 사이의 상호 관계성으로 인해 발생되는 환경 문제를 윤리적으로 인식하지 못하게 된다. 이러한 문제 의식과 현실 상황 속에서 본 연구는 햄버거 커넥션을 사례로 상품 소비와 윤리의 관계를 살펴보면서 학생들로 하여금 관계적 사고를 통해 상품과 학생 자신의 관계를 바라볼 수 있는 안목을 가질 수 있도록 하는 것이 지리 교육의 역할임을 주장하고자 한다.

This study was performed to evaluate the effectiveness of food commodity supplementary program for low-income, living alone elderly people. The subjects were 57 low income aged females who lived alone in Bucheon city. The food commodity supplementary program lasted for 6 months, supplying one meal per day consisting with grains, meat, vegetables, dairy and fruit. Dietary intake, anthropometric measurements, and blood profiles were assessed. After 6 months of food commodity supplemented period, dietary intakes of protein(p<0.05), calcium(p<0.05), iron(p<0.05) and vitamin B(p<0.001) were significantly increased. The mean weight(p<0.05) and BMI(p<0.05) were increased, and the frequency of BMI over 25kg/m$^2$ was also raised from 54.4% to 59.7%. Serum concentrations of total protein(p<0.001) and albumin(p<0.001) were significantly increased, indicating improvement of protein status. The frequency of anemia was decreased from 45.6% to 26.3%. However, the proportion of dyslipidemia was increased. In general the stable food commodity supplementary program was effective to improve general nutritional status of the poor aged who lived alone, however, nutrient intakes still did not meet RDA for the elderly and the rates of obesity and dyslipidemia were increased. Therefore, local government should provide more active food support program and the selection of food items for commodity should be evaluated at regular intervals.

This research explores the appropriate rubber pricing model and the consistent empirical evidence. This model has been derived from the utility function and firm profit-maximization model of commodity goods. The finding shows that the period t - 1 affects expected commodity price and expected profit of commodity production. In fact, a change in the world price of rubber in the past period led to a change in the expected price of rubber in the short run which influenced the expected rubber profit. As a result, the past-period free on board price has an entirety effect on expected farm price of rubber given an exchange rate. In addition, the rubber pricing model indicates that the profit of local farmer on rubber plant depends solely on the world price of rubber in the short run in case of Thailand. In an empirical study, it was found that a change in the price of ribbed smoke sheet 3 in Singapore Commodity Exchange significantly and positively determined the fluctuation of rubber price at the farm gate in Thailand which was consistent with the behavior of the Thai farmers. Both prices are also cointegrated in the long run. That is, the result states that the VECM is an appropriated pricing model for forecasting the farm price in Thailand.

Because of economic growth and the social trend to respect individuality, people's average commodity volume tends to increase. It makes people perceive the importance of storage space. The storage planning without consideration of commodity volume in the apartment can not satisfy the needs of residents. This study is developed focused on the $85m^2$ apartment which is the most representative and general type. The objectives of the study are to investigate the storage-capacity of $85m^2$ apartment offered by 4 construction companies to know the present storage condition, to investigate the average volumes and type of commodities in 30 families located in Seoul and Kyungkido to produce the necessary storage-capacity, and lastly to produce optimal storage-capacity and proportion of optimal storage-capacity considering the volume of the furniture owned by each resident. The results of the study are 1) the storage capacity for commodity volume in $85m^2$ apartment is $19.41m^3$. 2) the optimal storage-capacity which only counts the storage volume of built-in furniture is $17.14m^3$ 3) the proportion of optimal storage-capacity is 9.5% of the house-capacity.

이 논문은 헤지펀드 등 금융기관들의 금융적 투기가 효율시장가설의 주장과 달리 상품시장의 가격변동과 왜곡을 발생시킬 수 있고, 따라서 이러한 시장에 대한 엄격한 규제가 필요하다는 것을 주장한다. 효율시장가설은 헤지펀드가 가격위험을 헤징하고 정확한 가격을 발견하는데 중요한 역할을 한다고 주장하지만, 이 글은 이와 반대로 선물시장에서 헤지펀드의 거래가 증가할수록 가격이 장기균형가격으로 수렴하는 속도가저하되는 등의 왜곡현상이 나타난다고 주장한다. 또한 선물시장에서의 투기적 거래가 역사적인 수준으로부터 크게 벗어나지 않았다는 주장과달리, 과잉투기(excessive speculation)가 존재하였으며 과잉투기를 이끈 헤지펀드 등에 의해 선물가격이 비정상적으로 폭등하였다. 선물시장에서의 가격폭등은 현물-선물등가법칙에 의해 곧바로 현물시장의 가격폭등을 유발시키고, 그 결과 경제 전체적으로 나쁜 영향을 주게 된다.

A new approach to the commodity futures term structure model is introduced. The most salient feature of this model is that, once the interest rate model is given, the commodity futures price volatility is the only quantity that completely determines the model. As a consequence this model enables one to do away with the drudgeries of having to deal with the convenience yield altogether, which has been the most thorny point so far.

A commodity distribution problem with intertemporal storage facilities and dynamic transportation networks is proposed. mathematical integer programming methods and multiobjective programming techniques are used in the model formulation. Dynamic characteristics of commodity distribution problems are taken into account in the model formulation. storage facility location problems and transportation link addition problems are incorporated into the intertemporal multicommodity distribution problem. The model is capable of generating the most efficient and rational commodity distribution system. Therefore it can be utilized to provided the most effective investment plan for the transportation infrastructure development as well as to evaluate the existing commodity distribution system. The model determines simultaneously the most efficient locations, sizes, and activity levels of storage facilities as well as new highway links. It is extended to multiobjective planning situations for the purpose of generating alternative investment plans in accordance to planning situations. sine the investment in transportation network improvement yields w\several external benefits for a regional economy, the induced benefit maximization objective is incorporated into the cost minimization objective. The multiobjective model generates explicitly the trade-off between cost savings and induced benefits of the investment in transportation network improvement.
