We present an extension to the multi-product newsvendor problem by incorporating the retailer’s pricing decision as well as considering supplier quantity discount. The objective is to maximize the expected profit of the retailer through jointly determining the ordering quantities and selling prices for the products, subject to multiple capacity constraints. We formulate the problem as a General...

Advance selling before the time of consumption is now possible for even very small service providers, given new technologies (specifically, web-based transactions, biometrics and smart card technology). Moreover, recent research has revealed that advance selling can substantially improve profits without traditional price discrimination. However, that research was limited to monopoly settings. T...

An unavoidable aspect of electronic commerce is the collection of personal information. Although personal information is paramount to improving services and designing personalized offerings, its collection and use also generates privacy concerns. This study analytically examines the optimal information collection and usage practices in the presence of privacy costs. We use an analytical model i...

Rational choice when preferences are not required to be transitive and complete has been discussed in the literature for years. In this article transitivity and completeness of the preference relation is also not assumed. It will be shown that nevertheless the existence of a competitive equilibrium can be proven when those properties are replaced by a domination property which allows that there...

We present a comprehensive study of the use of value precedence constraints to break value symmetry. We first give a simple encoding of value precedence into ternary constraints that is both efficient and effective at breaking symmetry. We then extend value precedence to deal with a number of generalizations like wreath value and partial interchangeability. We also show that value precedence is...

Although Advance Selling and Probabilistic Selling differ in both motivation and implementation, we argue that they share a common characteristic—both offer consumers a choice involving buyer uncertainty. We develop a formal model to examine the general economics of purchase options that involve buyer uncertainty, explore the differences in buyer uncertainty created via these two strategies, an...
