TL;DR: In this paper, a class of term structure models with volatility of lognormal type is analyzed in the general HJM framework, and a two-factor version of the model is calibrated to the U.K. market price of caps and swaptions and to the historically estimated correlation between the forward rates.
Abstract: A class of term structure models with volatility of lognormal type is analyzed in the general HJM framework. The corresponding market forward rates do not explode, and are positive and mean reverting. Pricing of caps and floors is consistent with the Black formulas used in the market. Swaptions are priced with closed formulas that reduce (with an extra assumption) to exactly the Black swaption formulas when yield and volatility are flat. A two-factor version of the model is calibrated to the U.K. market price of caps and swaptions and to the historically estimated correlation between the forward rates.

17 Mar 1998TL;DR: In this article, a system and method for enabling on-line transactional services among sellers and buyers having no previous relationship with each other is presented, which includes a financial clearinghouse for receiving a request for goods or services from a buyer and making a real-time determination of a risk classification of the buyer utilizing an online repository of credit information.
Abstract: A system and method provides for enabling on-line transactional services among sellers and buyers having no previous relationship with each other. The system includes a financial clearinghouse for receiving a request for goods or services from a buyer and making a real-time determination of a risk classification of the buyer utilizing an on-line repository of credit information. The financial clearinghouse determines a risk-based discount fee as a function of the buyer's risk classification in order to establish a payment amount to the seller from the clearinghouse. If the transaction is authorized by the financial clearinghouse, the financial clearinghouse transmits the payment amount to the seller and transmits an invoice to the buyer for the purchase price of the transaction. The system can also include a broker coupled to the financial clearinghouse for providing an on-line order acceptance and processing capability between the buyers and sellers.

28 Mar 1995TL;DR: In this paper, a system for open electronic commerce with a customer trusted agent communicating with a first money module and a merchant trusted agent securely communicating with another money module is presented. But the system is limited to the case where the money modules inform their trusted agents of successful completion of payment, and the customer may use the purchased electronic merchandise.
Abstract: A system for open electronic commerce having a customer trusted agent securely communicating with a first money module, and a merchant trusted agent securely communicating with a second money module. Both trusted agents are capable of establishing a first cryptographically secure session, and both money modules are capable of establishing a second cryptographically secure session. The merchant trusted agent transfers electronic merchandise to the customer trusted agent, and the first money module transfers electronic money to the second money module. The money modules inform their trusted agents of the successful completion of payment, and the customer may use the purchased electronic merchandise.
