Empirical findings and theoretical studies suggest that firms adjust towards time-varying target leverage ratios. This paper studies the performances of the default probabilities generated from two stationaryleverage models with time-dependent and constant target ratios respectively. The...

This paper studies the discriminatory power and calibration quality of the structural credit risk models under the ¡§exogenous default boundary¡¨ approach including those proposed by Longstaff and Schwartz (1995) and Collin-Dufresne and Goldstein (2001), and ¡§endogenous default...

The theoretical prediction on targeted exchange rates expects mean reversion of the exchange rates. There is some empirical evidence to support this prediction. This paper presents a model for valuing European foreign exchange options in which the forward foreign exchange rate follows a...

This article develops a barrier option pricing model in which the exchange rate follows a mean‐reverting lognormal process. The corresponding closed‐form solutions for the barrier options with time‐dependent barriers are derived. The numerical results show that barrier option values and...

Based upon the Wei-Norman theorem, this paper presents a Lie-algebraic technique for the pricing of financial derivatives with time-dependent parameters. By exploiting the dynamical symmetry of the pricing partial differential equations of the financial derivatives, the new method enables us to...

In this paper we present a simple and easy-to-use method for computing accurate estimates (in closed form) of Black-Scholes barrier option prices with time-dependent parameters. This new approach is also able to provide tight upper and lower bounds (in closed form) for the exact barrier option...

This paper argues that the success of inflation targeting is principally the result of having a clear unambiguous goal, price stability, for monetary policy that is determined not only by the central bank but by the political authorities more generally. With such a goal in place, and with...

This paper attempts to identify whether the recent foreign reserve accumulation in Asian economies has been too extraordinary to recover the moderate level of reserves which depleted at the time of the currency crisis in 1997-1998. First of all, the level of reserves numerated by various...

This article presents a systematic and extensive empirical study on the presence of Markov switching dynamics in three dollar-based exchange rates. A Monte Carlo approach is adopted to circumvent the statistical inference problem inherent in the test of regime-switching behavior. Two data...

We estimate output gaps using three methods for Mainland China on annual data spanning 1982-2003. The estimates are similar and appear to co-move with inflation. Standard Phillips curves, however, do not fit the data well. This may reflect the omission of some important variable(s) such as the...
