Abstract:

The examples in this paper are drawn from one example of 'closed universe panels' ie. Sharescale Panels, which are set up on an ad hoc basis to measure particular product fields, usually to test the effect that a new brand might have in that field. Recently, however, Sharescale Panels have been set up to determine, inter alia, optimum price levels of existing brands - making use of the unique qualities of these panels to measure the effect of price.
