Abstract

We extend a modular pricing framework proposed by Ericsson and Reneby (1998, 2000, 2001) to derive a valuation formula for calls on leveraged equity, similar to Toft and Prucyk (1997). In contrast to their derivation via partial differential equations, we choose a more elegant probabilistic approach using change of numeraire techniques. Considerably extending previous firm value based option pricing models, our framework features exponentially increasing, finite maturity coupon debt, along with taxes and deviations from absolute priority. It enables us to study effects of debt maturity and debt growth on prices of equity options. Numerical results provide new insights into possible causes for pricing biases of the Black-Scholes formula.
