Hedging multiple price and quantity exposures

We examined the general hedging problem faced by a global portfolio manager or a pure exporting multinational firm, Most hedging models assume that these economic agents hold only a single asset in the spot market and are exposed only to a single source of price-quantity uncertainty. Such models are less relevant to many financial and exporting firms that face multiple sources of risk, In this study, we developed a general hedging model that explicitly recognizes that these hedgers are faced with multiple price and quantity uncertainties. Our model takes advantage of the full correlation structure of changes in spot prices, quantities, and forward prices. We performed simulations of the hedging model for a firm with two pairs of price and quantity exposures to demonstrate potential gains in hedging efficiency and effectiveness.
