In this paper we formulate the Risk Management Control problem in the interest rate area as a constrained stochastic portfolio optimization problem. The utility that we use can be any continuous function and based on the viscosity theory, the unique solution of the problem is guaranteed. The...

The complexity of managing physical and financial risk throughout the commodity production, processing and merchandising chain presents numerous challenges. To solve this problem commercials are increasingly turning to Energy and Commodity Transaction Risk Management (E/CTRM) systems. Still,...

Multiple delivery specifications exist on nearly all commodity futures contracts. Sellers are typically allowed to choose among several grades of the underlying commodity. On the delivery day, the futures price converges to the spot price of the cheapest-to-deliver grade rather than to that of...

This paper is the first to study the hedging of price risk with uncertain payment dates, a frequent problem in practice. It derives a variance-minimizing hedging strategy for two settings, the first employing linear contracts with different times to maturity and the second allowing for...

This paper investigates corporate hedging under regret aversion. Regret-averse firms try to avoid deviations of their hedging policy from the ex post best policy, an intuitive consideration if one has to justify one's decisions afterward. The study presents a model of a firm that faces uncertain...

This paper studies the impact of counter-party default risk of forward contracts on a firm's production and hedging decisions. Using a model of a risk-averse competitive firm under price uncertainty, it derives several fundamental results. If expected profits from forward contracts are zero, the...
