We study a coordination contract for a supplier-retailer channel producing and selling a fashionable product exhibiting a stochastic price-dependent demand. The product's selling season is short, and the supply chain faces great demand uncertainty. We consider a scenario where the supplier...

Newsvendor models have been well-established for studying supply chain management problems with fashionable products. In this paper, we explore the mean-downside-risk (MDR) and mean-variance (MV) newsvendor models under both the exogenous and endogenous retail price decision cases. We first...

In the case of group buying, the information associated with the number of...

We consider a duopolistic Bertrand competition setting in which competing firms can turn into intermediaries. The intermediation option allows firms to take advantage of the rival firm’s low price. We then give conditions for the existence of equilibrium.

A fashion supply chain characterized by a long lead time and a short selling season is considered in this paper. Facing demand uncertainty, the risk averse retailer has two opportunities to make order decisions before the demand is realized. The risk aversion is modelled as a penalty to the...
