Ho–Lee model. In financial mathematics, the Ho-Lee model is a short-rate model widely used in the pricing of bond options, swaptions and other interest rate derivatives, and in modeling future interest rates. [ 1]: 381 It was developed in 1986 by Thomas Ho [ 2] and Sang Bin Lee. [ 3]
A credit-linked note (CLN) is a form of funded credit derivative. It is structured as a security with an embedded credit default swap allowing the issuer to transfer a specific credit risk to credit investors. The issuer is not obligated to repay the debt if a specified event occurs. This eliminates a third-party insurance provider.
The Heath–Jarrow–Morton ( HJM) framework is a general framework to model the evolution of interest rate curves – instantaneous forward rate curves in particular (as opposed to simple forward rates ). When the volatility and drift of the instantaneous forward rate are assumed to be deterministic, this is known as the Gaussian Heath ...
The airline ticket may be one of two types: a paper ticket, which comprises coupons or vouchers; and an electronic ticket (commonly referred to as an e-ticket ). The ticket, in either form, is required to obtain a boarding pass during check-in at the airport. Then with the boarding pass and the attached ticket, the passenger is allowed to board ...
A voucher is an accounting document representing an internal intent to make a payment to an external entity, such as a vendor or service provider. A voucher is produced usually after receiving a vendor invoice, after the invoice is successfully matched to a purchase order. A voucher will contain detailed information regarding the payee, the ...
Coupon collector's problem. In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more ...
Merton model. The Merton model, [1] developed by Robert C. Merton in 1974, is a widely used "structural" credit risk model. Analysts and investors utilize the Merton model to understand how capable a company is at meeting financial obligations, servicing its debt, and weighing the general possibility that it will go into credit default.

A trajectory of the short rate and the corresponding yield curves at T=0 (purple) and two later points in time. In finance, the Vasicek model is a mathematical model describing the evolution of interest rates. It is a type of one-factor short-rate model as it describes interest rate movements as driven by only one source of market risk.
