TITLE: On Hedging American Options (or hedging with them) under Model Uncertainty
ABSTRACT:
We consider as given a discrete time financial market with a risky asset and options written on that asset, and we determine both the sub- and superhedging prices of an American option in the model independent framework. We do this first when some (path dependent) European options are available for static hedging. We then analyze what happens when some American options are added to the mix of options that are available for hedging.
