This paper presents a discrete--time equity derivatives pricing model with default risk in a no--arbitrage framework. Using the equity--credit reduced form approach where default intensity mainly depends on the firm's equity value, we deduce the Arrow--Debreu state prices and the explicit pricing result in discrete time after embedding default risk in the pricing model. We prove that the discrete--time defaultable equity derivatives pricing has convergence stability, and it converges weakly to the continuous--time pricing results.
