Pricing matrix model: dealing with uncertainty.

A previous publication in this journal showed that the pricing matrix model (PMM) allows an assessment of the pricing potential of a new innovative product. When the PMM is going to be used for the determination of a drug price for a new drug in the strategic product planning process, it is important that this methodology is reliable. In the initial paper the PMM only yielded an expected price for the new antidepressant without generating an estimate of the probability that the new drug would indeed be listed at this expected price. In this manuscript we present various methodologies to deal with uncertainty in the PMM. We introduce the concept of price acceptability curves. The conclusion of this paper is that the incorporation of uncertainty into the PMM will lead to a more accurate assessment of the pricing potential of a new drug.
