We introduce the Veblen residue, demonstrate that the phrase &quot;Price on Demand&quot; corresponds to a pole of order one at the point at infinity on the Riemann sphere of desire, and establish the Fundamental Theorem of Luxury: every non-constant luxury price has at least one root in the consumer&apos;s solvency.</description><pubDate>Tue, 07 Jul 2026 00:00:00 GMT</pubDate><category>complex-analysis</category><category>mathematical-economics</category><category>satire</category><category>Veblen-goods</category><author>D.
