An effectively branded product is characterized by its metavalue (which includes the brand value), but only the limited population aware of the product/brand well enough is able to embrace its metavalue. Not all of them value the product/brand alike; and only those valuing it the highest in this moment buy it in this very moment. It would be assumed that this population, the audience, takes the form of a normal distribution. Consequently the price-demand curve would take the shape of the integral of this normal distribution. But, as the (meta-) value of the product/brand also is a function of its price (i.e. status value), a continuous price-demand curve is only hypothetical. A discussion about the dynamics of the price/value/demand relations of branded products can be found as an appendix to my General Theory of Marketing.
General Theory of Marketing.
The core of evolutionary marketing is value, being the factor deciding the buyer's (customer's) buying decision. And the buyer's valuing is a consequence of a complex of conscious and subconscious processes best explained and analyzed by evolutionary psychology. My marketing theory is founded on this notion of value and the different aspects of it. Any theory of branded products (as this is) has to offer an analysis from every angle of how the buyers' subjective valuing affect transactions. Consequently, my Transaction Equation is the pivotal model, and the Dynamics of the Evaluating Audience is a very specific concept demonstrating changes of value as a consequence of changes of price and communication – unique of evolutionary marketing.
