This paper studies the competitive and cooperative selection of inventory policies in a two-echelon supply chain with one supplier and N retailers. Stochastic demand is monitored continuously. Retailers incur inventory holding and backorder penalty costs. The supplier incurs holding costs for its inventory and backorder penalty costs for backorders at the retailers. The latter cost reflects the...

A ̄rm's operations require an input that can only be procured from outside. There are multiple potential suppliers, who privately observe their marginal production costs. The ̄rm faces a revenue function that is increasing and concave in the input quantity. The objective is to identify a procurement strategy that maximizes the ̄rm's expected pro ̄ts. It is known that an optimal strategy can be a...
