In this paper we have derived the analytical kernels of the pricing formulae of the CEV knockout options with time-dependent parameters for a parametric class of moving barriers. By a series of similarity transformations and changing variables, we are able to reduce the pricing equation to one...

Time dependent barrier options have barrier periods covering a portion of option life. This feature makes them hybrids of barrier options and ordinary European options. There are two types of time dependent barrier options: 1. front end barrier options; 2. rear end barrier options. The options...

Although the affine Gaussian term-structure model has been a workhorse model in termstructuremodelling, it remains doubtful whether it is an appropriate model in a low interest rate environment. This paper uses an alternative quadratic Gaussian-term structure model which is well known to be as...

Using a non-Gaussian affine term-structure model, this paper evaluates the effectiveness of the date-based forward guidance at the zero lower bound. The model extracts the expected dynamics of two state variables (the short-term interest rate and its mean) embedded in the entire Treasury yield...

This paper develops a model based on a target-zone approach in which the dynamics of government bond yields follow a quasi-bounded process, such that the zero lower bound (ZLB) can be breached if the probability leakage condition of the dynamics is met. A one-sided U-shaped bond yield...

This paper investigates the determinants of variations in the yield spreads (swap spreads) between Hong Kong dollar interest rate swaps and Exchange Fund paper for a period from July 2002 to April 2008. A vector error-correction model is used to analyze the impact of various shocks on swap...

The economic-political instability of a country, which is tied to its credit risk, often leads to sharp depreciation and heightened volatility in its currency. This paper shows that not only the creditworthiness of the euro-area countries with weaker fiscal positions but also that of the member...

In this paper we have formulated a simple theoretical model for the dynamics of the time-varying target leverage ratio of a firm under some assumptions based upon empirical observations. In our theoretical model the time evolution of the target leverage ratio of a firm can be derived...
