The average interest rate call pricing model proposed by Longstaff (1995) has been modified and extended in a way that the underlying average rate is constructed by observable and commonly-used discrete rate rather than unobservable and continuous-time short rate. Additionally, methods used by Levy (1992) and Vorst (1992) for Asian currency options arc applied to price the average interest rate call; and two approximation formulas for pricing this average call arc derived. The new developed formulas are not only consistent with the current term structure prevailed in the market. but also ready to apply since the rates used to compute the average rate arc observable. Both the hedging strategy and the applications for the new contract arc also discussed in the paper |
