A Market-Based Real-Asset Martingale Valuation Approach to Optimum Inventory Control
نویسندگان
چکیده
We propose a novel approach to optimum inventory control by modeling a commodity trader’s inventory investment as a portfolio of forward commitments taking explicit account of the dynamics of demands, costs and prices in open markets. We apply the robust real-asset martingale valuation methodology to derive a closed-form solution for the inventory value and a simple and intuitive optimality condition. Numerical analysis verifies this condition and demonstrates that the resulting optimum policy has robust properties.

The PF manager is assumed to follow a maximal fund valuation problem facing an extended set of risk factors: due to the longevity of the PF members, the inflation affecting salaries in real terms and future incomes, interest rates and market factors affecting jointly the PF liability and asset p...

متن کاملA Discrete Time Equivalent Martingale Measure
An equivalent martingale measure selection strategy for discrete time, continuous state, asset price evolution models is proposed. The minimal martingale law is shown to generally fail to produce a probability law in this context. The proposed strategy, termed the Girsanov principle, performs a multiplicative decomposition of asset price movements into a predictable and martingale component wit...
