The purpose of this study was to investigate the distribution of functions and forms of hedging devices in the abstracts of master’s theses in two languages (English and Persian) written by Iranian students. To this end, 70 abstracts of M.A. theses were selected as the corpus. The total number of words in both English and Persian abstracts were 19,933 and 23,073, respectively. The categories of...

this study set out to investigate the similarities and differences in frequency of incidence and type of hedging devices used in research articles written by iranian and non-iranian writers. for the purposes of the study, a corpus including 40 agriculture articles in english (20 written by iranian and 20 by non-iranian writers) were selected. collection and classification of the hedging devices...

To deal with severe drought when water supply is insufficient hedging rule, based on hedging rule curve, is proposed. In general, in discrete hedging rules, the rationing factors have changed from a zone to another zone at once. Accordingly, this paper is an attempt to improve the conventional hedging rule to control the changes of rationing factors. In this regard, the simulation model has emp...

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...

One of the most successful approaches to option hedging with transaction costs is the utility based approach, pioneered by Hodges and Neuberger (1989). Judging against the best possible tradeoff between the risk and the costs of a hedging strategy, this approach seems to achieve excellent empirical performance. However, this approach has one major drawback that prevents the broad application of...

In this paper, we consider the problem of mean-variance hedging in an incomplete market where the underlying assets are jump diffusion processes which are driven by Brownian motion and doubly stochastic Poisson processes. This problem is formulated as a stochastic control problem and closed form expressions for the optimal hedging policy are obtained using methods from stochastic control and th...

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...

This work is devoted to the discrete time hedging of the American option on a dividendpaying stock with a convex payoff, the particular case of which is American call option. Perfect hedging requires continuous trading in time and knowledge of the partial derivative of the value function of the American option in the underlying asset. Neither one can trade continuously in time nor the closed-fo...

The martingale optimal transport problem is motivated by model-independent bounds for the pricing and hedging exotic options. In the simplest one-period model, the dual formulation of the robust superhedg-ing cost differs from the standard optimal transport problem by the presence of a martingale constraint on the set of coupling measures. The one-dimensional Brenier theorem has a natural exten...
