This paper studies collusion in repeated Bertrand oligopoly when stochastic demand levels for the product of each rm are their private information and are positively correlated. It derives general su cient conditions for e cient collusion through communication and a simple grim-trigger strategy. This analysis is then applied to a model where the demand signal has multiple random components whic...

It is important to share demand information among the members in supply chains. In recent years, production and inventory systems with advance demand information (ADI) have been discussed, where advance demand information means the information of demand which the decision maker obtains before the corresponding actual demand arrives. Appropriate production and inventory control using demand info...

I this paper we examine the impact of different types of advance demand information on firm profit and on the benefits of resource flexibility. Specifically, we consider a firm that must choose capacities of resources that will be used to satisfy stochastic demand for multiple products, where demands follow a multivariate normal distribution. Prior to the capacity decision, the firm receives in...
