Electricity generators in most deregulated markets simultaneously operate in both financial (contract) and physical (spot) markets. Decisions in each of these markets are not mutually exclusive, and in the case of imperfectly competitive scenarios generating companies can use their market power to influence spot and contract prices. A model of oligopolistic market equilibrium is presented where...

A futures contract is an agreement between a seller and a buyer that calls for the seller to deliver to the buyer a specified quantity and grade of an identified commodity, at a fixed time in the future, and at a price agreed in the contract. Stock index futures contract specify an equity index as the underlying asset. Arbitrage opportunity exists when the actual futures price deviates from the...

W e analyze a decentralized supply chain with a single risk-averse retailer and multiple risk-averse suppliers under a Conditional Value at Risk objective. We define coordinating contracts and show that the supply chain is coordinated only when the least risk-averse agent bears the entire risk and the lowest-cost supplier handles all production. However, due to competition, not all coordinating...

This paper develops a dynamicmodel in a one-supplier-one-retailer fresh agricultural product supply chain that experiences supply disruptions during the planning horizon.The optimal solutions in the centralized and decentralized supply chains are studied. It is found that the retailer’s optimal order quantity and the maximum total supply chain profit in the decentralized supply chain with whole...

Forecast sharing is studied in a supply chain with a manufacturer that faces stochastic demand for a single product and a supplier that is the sole source for a critical component. The following sequence of events occurs: the manufacturer provides her initial forecast to the supplier along with a contract, the supplier constructs capacity (if he accepts the contract), the manufacturer receives ...

β-lactamases are bacterial enzymes that confer resistance to β-lactam antibiotics, such as penicillins and cephalosporins. There are four classes of β-lactamase enzymes, each with characteristic sequence and structure properties. Enzymes from class A are the most common and have been well characterized across the family; however, less is known about how physicochemical properties vary across th...

In this paper, the authors focus on examining the coordination mechanisms for a two-stage supply chain comprising one supplier and one retailer. The authors consider such a channel relationship that the transaction quantity between the two members is sensitive to the supplier’s inventory level and that the supplier’s unit inventory holding cost has a linear stepwise structure. They devise a coo...

T paper studies a buyer’s procurement strategies in a two-stage supply chain with price-sensitive demand. The buyer procures a product from a supplier and then sells to the marketplace. Market demand is stochastic and depends on the buyer’s selling price. The supplier’s production cost is private information, and the buyer only knows the distribution of the cost. Both the buyer and the supplier...
