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 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 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...

We compare the dynamic hedging performance of the deterministic local volatility function approach with the implied/constant volatility method. Using an example in which the underlying price follows an absolute diffusion process, we illustrate that hedge parameters computed from the implied/constant volatility method can have significant error even though the implied volatility method is able t...

Flood hedging reservoir operation is when a pre-storm release creates a small flood downstream to reduce the likelihood of a more damaging but uncertain larger flood in the future. Such pre-storm releases before a flood can increase reservoir storage capacity available to capture more severe flood flows, but also can immediately increase downstream flood damage and reduce stored water supply. T...

This paper addresses quantity risk in the electricity market and explores several ways of managing such risk. The paper also addresses the hedging problem of a load-serving entity, which provides electricity service at a regulated price in electricity markets with price and quantity risk. Exploiting the correlation between consumption volume and spot price of electricity, an optimal zero-cost h...

A super-replication problem with a gamma constraint, introduced in [12], is studied in the context of the one-dimensional Black and Scholes model. Several representations of the minimal super-hedging cost are obtained using the characterization derived in [3]. It is shown that the upper bound constraint on the gamma implies that the optimal strategy consists in hedging a conveniently face-lifte...

We develop a flexible discrete-time hedging methodology that minimizes the expected value of any desired penalty function of the hedging error within a general regimeswitching framework. A numerical algorithm based on backward recursion allows for the sequential construction of an optimal hedging strategy. Numerical experiments comparing this and other methodologies show a relative expected pen...

In the broad literature of corporate risk management classic models of optimal hedging assume a one-period hedging decision, and therefore no financing need arises to maintain the hedge position. The multi-period models are usually based on the assumption of no liquidity constraints, and accordingly the eventual financing need can always be met from the market. As a consequence of the recent cr...
