In the current financial crisis, promoting rapid developments of gold industry, ensuring healthy operations of national economy, and actively developing the gold futures market are very important. Functioning of the gold futures market will determine the gold market maturity and integrity. Risk transfer is one of the two basic functions of futures market. The risk transfer function is realized ...

This paper looks at the development of dynamic hedging strategies for typical pension plan liabilities using longevity-linked hedging instruments. Progress in this area has been hindered by the lack of closed-form formulas for the valuation of mortalitylinked liabilities and assets, and the consequent requirement for simulations within simulations. We propose use of the probit function along wi...

In bet hedging, organisms sacrifice short-term success to reduce the long-term variance in success. Delayed germination is the classic example of bet hedging, in which a fraction of seeds remain dormant as a hedge against the risk of complete reproductive failure. Here, we investigate the adaptive nature of delayed germination as a bet hedging strategy using long-term demographic data on Sonora...

The discourse of the discussion in research articles is regarded to be of considerable significance—as in this section the findings are interpreted in light of previous research and the authors’ argumentations are put forward as a major contribution (see Hyland, 1999). For this reason, the content and structure of the discussion section have been explored in several studies; however, little att...

In financial markets, errors in option hedging can arise from two sources. First, the option value is a nonlinear function of the underlying; therefore, hedging is instantaneous and hedging with discrete rebalancing gives rise to error. Frequent rebalancing can be impractical due to transaction costs. Second, errors in specifying the model for the underlying price movement (model specification ...

This paper presents hedging strategies for European and exotic options in a Lévy market. By applying Taylor's Theorem, dynamic hedging portfolios are constructed under different market assumptions, such as the existence of power jump assets or moment swaps. In the case of European options or baskets of European options, static hedging is implemented. It is shown that perfect hedging can be achi...

This paper addresses the optimization of the continuous-flow model of a single-stage single-product manufacturing system with constant demand and transportation delay from the machine to the inventory. The machine is subject to either time-dependent or operation-dependent failures. The production is controlled by a hedging point policy. The goal is to determine the optimal hedging point, which ...

We study optimal hedging of barrier options using a combination of a static position in vanilla options and dynamic trading of the underlying asset. The problem reduces to computing the Fenchel-Legendre transform of the utility-indifference price as a function of the number of vanilla options used to hedge. Using the well-known duality between exponential utility and relative entropy, we provid...
