Term Structure Models and the Black-Scholes Model: a Comparison The term structure display: Time measurement, rate, a "stream idea" From the monetary displaying viewpoint, the Black Scholes model is not a unique instance of a term structure display – subsequently "term structure" Correlations of the securities of the term structure: Principal segment techniques Ho, Thomas S.

sans arbitrage Natural Gas Model Valuation Component of the Model Contingent claims on the NG spot and prospects costs Implied cost to convey: The term structure Futures contracts deciding the inferred cost of convey The one time frame cost to convey is comparable to the survival rate Dynamics of the term structure: The term structure of cost to convey and the spot rates dS = c(t) S dt + σ (t) S dz dc(t) = F( c(t, T), t) dt + σ * dw Applications: Energy Risk Modeling

Preliminary Results on Dynamic Hedging Application Component of the Model The fates term structure developments have two elements: "Cost" (85%), "Cost to Carry" (14%), 3 rd vector (0.3%) The cost of convey developments has one element: level development (99.5%) and 2 nd calculate (0.4%) Correlation of the spot cost and cost to convey: low The utilization of key rate spans on the cost to convey and the spot cost for supporting Applications: Energy Risk Modeling
