The Convertible Bonds (CBs) market has witnessed an unprecedented level of activity over the last few years not only in developed countries such as the United States but also in BRICK countries such as China. Exploring new properties of CBs or CBs with clauses becomes important for academia communities in financial mathematics. In this paper, we build two coupled partial differential equations (PDEs) for pricing a callable CB, and find a newly identified inherent property of this bond. The new property is that the conversion ratio will not affect the critical recall time indicating the time be...

Regime-switching models have been heavily studied recently, as they have some clear advantages of over other non-constant volatility model to resolve the so-called smirk effect displayed when constant volatility models are used to price financial derivatives such as options. However, due to the increased model complexity, the associated computational effort usually increases as well, particularly when they are used to price American-style options. In this paper, a novel computational approach based on integral equations is presented. A distinctive feature of our approach, in comparison with ot...

In this paper, the pricing problem of callable–puttable convertible bonds written on a single underlying asset is studied with an integral equation (IE) approach. The complication of the pricing exercise results from the tangled presence of callability, puttability, as well as conversion, which have led to possible coexistence of two moving boundaries at the same time, depending on the call price, the put price, and the conversion ratio. If a callable–puttable convertible bond needs to be priced at a time sufficiently far away from the expiry, only the moving boundary associated with the p...
