If you understand any of this you're probably an economist and I hate you:
Smith's Law: cost of production*(demand/supply)=fundmental price.
Obviously only applies to the stupid little Test Models freemarketeers masturbate to, but even within a "dirty" Marx-Smith Model you're really only adding onto that basic equation.
Including the ghastly hideousness of Raymond's* Inconstant: Gross Costs of Production*(cost of bribes to avoid regulation*SQRTthe waist line of the companies' CEO/the waistline of their spouse)
Economics=Srs but poorly explained Bizness
* Named for Lee "meat flaps" Raymond, Ex-head of ExxonMobil, who's chin justifies all fat jokes. Do a google image search, you'll know what I'm talking about.
