Making a living out of wordonomics

There is a proliferation of made up words that tack on the word onomics to a brand name., all inspired by Reagonomics and Freakonomics. All these initiated by the brands themselves. This of course an attempt to position the brand as most suitable for the current economic conditions. Examples include

  1. 3conomics  (Wendy’s 3 meals under $3 deal)
  2. Suaveonomics
  3. DiGiornomics

Does this help the brand to associate with something that is not doing so well?

Why position your brand for tough economic conditions? So are the products the equivalent of what economists call Giffen goods?

When the economy improves will people switch from your brands to what they perceive as better brands?
