In this paper, we examine the nature of optimal inventory policies in a system where a retailer manages substitutable products. We first consider a system with two products 1 and 2 whose total demand is D and individual demands are negatively correlated. A fixed proportion of the unsatisfied...

In this paper, we study dynamic alliance formation among agents in competitive markets. We look at n agents selling substitutable products competing in a market. In this setting, we look at models with deterministic as well as stochastic demand, and use a two stage approach. In Stage 1, agents...

We examine a decentralized supply chain supply chain in which a single assembler buys complementary components from n suppliers and assembles the final product in anticipation of demand. Players take actions in the following sequence. First, (Stage 1) the suppliers form coalitions between...
