Merton's Jump Diffusion Model (1976)

This is an application of Monte Carlo methods [1] to the pricing of options on stocks when the underlying asset has occasional jumps in the trajectories. Merton [2] describes such jumps as "idiosynchratic shocks affecting an individual company but not the market as a whole". The jump component makes the distribution of prices leptokurtic (high peak, heavy tails), a feature typical of market data.

The model builds on the standard Brownian motion, which can also be generated using the willow tree.
