Question:
Consider the ‘spot dividend’ model, for which the partial differential equation on a call price C(St, t, T ), for a single dividend going ex at time τ is given by:
Show, to first order in the dividend , that an approximate solution for t
and
This approximation is sometimes referred to as the ‘split dividend model’, and can be used as a short cut for approximating calibration of the spot dividend model to European options.
