Abstract
This paper extends the user-cost approach of Hancock (1985, 1991) in two ways. First, our model allows financial firms to behave strategically as well as competitively. Second, we do not assume that financial firms are risk-neutral. Our main object is to derive the index of the degree of competition under dynamic uncertainty using this extended model. In our model, the classification of financial goods into inputs and outputs is always consistent with the classification based on the sign of each of the partial derivatives of the variable cost function with respect to financial goods.
