Aside from taxes, the factors shown to contribute to regional and even local differences in gasoline prices include proximity of supply, supply disruptions, competition in the local market and environmental programs. Of interest in this paper is proximity of supply. It has been hypothesized that areas farthest from the Gulf Coast （the source of nearly half of the gasoline produced in the United States and, thus, a major supplier to the rest of the country） tend to have higher prices. To test this hypothesis, the paper assembles state level monthly retail gasoline data for the period 1983 to 2007 for five states with oil refineries （Alabama, Georgia, Texas, Mississippi and Louisiana） and five states without refineries （Arkansas, Tennessee, North Carolina, South Carolina and Florida）. The analysis employs dynamic correlation, regression, cointegration and vector autoregressive methods. Overall, the results show that retail gas prices in states with refineries and those without refineries tend to move in the same direction over time. The small differences observed over time may suggest that price shocks take a short time to be felt nationwide.展开更多

When the supplier considers distributional fairness of loss aversion and extra-gain guilty, extra-gain guilty concern reduces the optimal wholesale and retail price, and improves supply chain performance. When the first or the second retailer considers distributional fairness and peer-induced fairness, extra-gain guilty concerns decrease the optimal wholesale and retail price but increase the profit of all supply chain members only when the level of loss aversion is large enough and the level of extra-gain guilty is less than 1/2. However, when the level of loss aversion is small and the level of extra-gain guilty is less than 1/2, extra-gain guilty has no influence on supply chain performance. The analysis reveals that the supply chain performance can be further improved by considering fairness of extra-gain guilty.展开更多

The low cost of medical services means that public hospitals can legitimately use the sale of pharmaceuticals to subsidize the provision of services. Moreover, the policy of controlling the rate of return gives public hospitals a further incentive to buy and sell high-cost pharmaceuticals. In addition, the policy of independent pricing together with the laxity of the system for approving new drugs allows the makers of pharmaceutical products to charge higher prices and facilitates public hospitals＇ sale of high-priced drugs. All of these problems result from inappropriate government controls. Therefore, the basic strategy for solving the problem of inflated pharmaceutical prices should be to lessen government controls on healthcare, open up retail sales of prescription medicines, and reform the public healthcare system and medical insurance reimbursement, breaking the monopoly of public hospitals.展开更多
