Option Pricing under Jump Uncertainty

We study the problem of European and American option pricing in the presence of uncertainty about the timing and the size of a jump in the price of the underlying. In a non-Markovian market setting, we characterize the worst-case option price as the minimal solution of a constrained backward stochastic differential equation and derive a pricing PDE in the special case of a Markovian market model. In a Black-Scholes market, explicit pricing formulae for European call and put options are obtained, and we study properties of the American put option price numerically.
