Complete Markets and Martingale Representation
Our objective in this chapter is to study completeness of the market model. We continue to restrict attention to finite market models: although our initial results can be stated in a more general framework, the proofs we give rely heavily on the finite nature of the model, and we show in the later sections that completeness depends strongly on the fine structure of the filtrat ions, a feature that is not easily formulated for more general models.
