5 ABSTRACT This article provides a simple model for pricing and hedging options in the presence of jumps and liquidity costs. In the article, liquidity risk is modelled via a stochastic supply curve function and a jump-diffusion process is approximated by a Markov chain. Local risk minimization incorporating liquidity risk is proposed to price and hedge European options in this discrete10 time ...

This paper investigates the effects of mortgage-backed securities (MBS) hedging activity on interest-rate volatility and proposes a model that takes these effects into account. An empirical examination suggests that the inclusion of information about MBS considerably improves model performance in pricing interest-rate options and in forecasting future interest-rate volatility. The empirical res...

This study examined the effect of explicit instruction of hedging on English forSpecific Academic Purposes (ESAP) reading comprehension performance ofEnglish Language Learning (ELL) university students. A reading comprehensiontest was developed and validated as the pretest and the posttest. The test, includingitems for assessing the comprehension of the students in their area of specialization,...

Hedging academic claims has been recognized as one of integral pragmatic features of academic writing in which most EFL academic writers seem to face substantial problems. Explicit instruction has been proposed by some scholars as an effective approach to make EFL writers aware of the importance, different forms, and pragmatic functions of hedging devices some of which are polysemous and polypr...

In this paper we assess the partial hedging problems by formulating hedging strategies that minimize conditional value-at-risk (CVaR) of the portfolio loss under stochastic interest rate environment. The combination of stochastic interest and CVaR hedging method makes the valuing approach more complex than the existing model with constant interest rate. We take up two issues in searching the op...

While most research on hedging has focused on foreign currency exposures, analysis of jet fuel price exposure in the airline industry and the effects of both financial and operational hedging on this exposure provides valuable insights into risk management. Exposure and hedging in the airline industry is relatively straightforward compared to foreign exchange hedging by multinationals. We inves...

W consider a firm that invests in capacity under demand uncertainty and thus faces two related but distinct types of risk: mismatch between capacity and demand and profit variability. Whereas mismatch risk can be mitigated with greater operational flexibility, profit variability can be reduced through financial hedging. We show that the relationship between these two risk mitigating strategies ...
