This paper studies the optimal pricing scheme for a monopolistic marke
ting research consultant who sells high-cost proprietary marketing inf
ormation to her oligopolistic clients in the manufacturing industry. I
n designing an optimal pricing strategy, the consultant needs to fully
consider the behavior of her clients, the behavior of the existing an
d potential competitors to her clients and the behavior of her clients
' customers. We show how the environment uncertainty, the capability o
f clients' internal research department, and the number of potential c
lients can affect the optimal pricing scheme.
