Capacity investment in supply chain with risk averse supplier under risk diversification contract

In a supply chain with one risk neutral manufacturer and one risk averse supplier, we propose a risk diversification contract under which the manufacturer shares the losses of excess capacity and inadequate capacity with the supplier, and a side payment is transferred from the supplier to the manufacturer. Under the Conditional Value-at-Risk (CVaR) criterion, risk diversification contract has a Pareto improvement and can allocate system performance appropriately in both symmetrical and asymmetrical demand information. In addition, this contract can coordinate supply chain and has a larger market than an option, capacity reservation, payback, revenue-sharing contract under the symmetrical demand information.
