# Model of sales of a new product

I am looking for any popular model to calculate sales of a new product under the assumption that some goodnesses of the product are given.

For example, the novelty $N$ and usefulness $U$ of a new product are given, the sales $S$ of it might be calculated as $S(N,U) = N^\alpha + U^\beta + c$ ($1 \leq \alpha, 1 \leq \beta$, and $c$ is a constant number).

I believe this model is too naive and a researcher proposed some popular model. But, I could not find it.

• If possible, would you mind expanding a bit more on the specifics of what you were interested in? For example, besides the inclusion of a "novelty" and "usefulness" parameter, are there any other features you'd like the model to have? Is there any specific way you'd like these parameters defined? Is your interest primarily for a theory model, or an empirical work (where estimation is necessary)? Are there any specific fields you're interested in applying this model to (for example, industrial organization, firm decision making, etc.)? – AndrewC Jun 20 '18 at 8:43
• @AndrewC Thank you for your comment! I am doing literature survey of previous studies that build a model of the revenue of a new product. So, any model about it is welcome. More specifically, my interest is in innovative products, so, the novelty of a new product is important attribute for me. – rkjt50r983 Jun 20 '18 at 9:26
