Elasticity of demand. A. An organism’s demand for a given reinforcer is defined as elastic if consumption drops significantly as the unit price (i.e.,
FR divided by unit administered) of the reinforcer is raised. B. The maximal price (Pmax) of a reinforcer and maximal output of responses (Omax) of the organism under a given set of conditions are both parameters that can be used to describe behavior with regard to
a given reinforcer. See text for details.
