Mean-Variance Trade-Offs in Supply Contracts 

Date: 10/2006 Author(s): Martínez de Albéniz, Victor; Simchi-Levi, David Editor(s): CIMS - Center for Innovation Marketing and Strategy Document type: Article in Journal (refereed) We study the trade-offs faced by a manufacturer signing a portfolio of long-term contracts with its suppliers and having access to a spot market. The manufacturer incurs inventory risk when purchasing too many contracts and spot price risk when buying too few. We quantify these risks for a single selling period by studying the profit mean and variance ... More information

We characterize the ... More information   Read related article
