Sensitivity with Respect to the Yield Curve: Duration in a Stochastic Setting
نویسندگان
چکیده
Bond duration in its basic deterministic form is a concept well understood. Its meaning in the context of a yield curve on a stochastic path is less well developed. We extend the basic idea to a stochastic setting. More precisely, we introduce the concept of stochastic duration as a Malliavin derivative in the direction of a stochastic yield surface modeled by the Musiela equation. Further, using this concept we also propose a mathematical framework for the construction of immunization strategies (or delta hedges) of portfolios of interest-ratesensitive securities with respect to the fluctuation of the whole yield surface.

Sensitivity of Bond Portfolio's Behavior with Respect to Random Movements in Yield Curve: A Simulation Study
The bond portfolio management problem is formulated as a stochastic program based on interest rate scenarios. The coefficients of the resulting program are subject to errors of various kind. In this paper, we complement the theoretical stability results of [10] by simulation experiments. Adapting the approach of [16] to problems based on perturbed yield curves, we then provide bounds for the op...
متن کاملSensitivity and uncertainty analysis of sediment rating equation coefficients using the Monte-Carlo simulation (Case study: Zoshk-Abardeh watershed, Shandiz)
The sediment load estimation is essential for watershed management and soil conservation strategies. The sediment rating curve is the most common approach for estimating the sediment load when the observed sediment records are not available. With regard to the measurement errors and the limitation of available data, the sediment rating curve has a degree of uncertainty which should be accounted...
متن کاملEvaluation of Price Setting Models in Iran’s Economy (DSGE Approach)
Despite the consensus on the importance of nominal rigidities, there is no general agreement among monetary economists regarding the most appropriate and consistent pricing model that must be used to assess the effects of monetary policies in the economy. Due to the lack of empirical evidence with relation to the pricing behavior of Iranian firms, there is no general agreement on how to introd...
متن کاملDifferent sowing dates affected cotton yield and yield components
This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...
