There are ALOT more factors than Supply and Demand...(pricing falls from these 2...and is thus derived...in >theory< :-)_)
BUT...I feel inclined to poke my head in here...
Weather, shoplifting and fashion ARE market forces...because they relate to how product cost or material supply is derived.
Bad weather does indeed affect the supply of citrus fruit...for example.
Shifting fashion sense has certainly reduced demand for double-knit polyester leisure suits...has it not?
HOWEVER...this thread, IIRC, began by someone trying to call government intervention a "market force". THIS...is not correct. While government intervention does indeed affect the market...by economic definition it is NOT a "market" force....but an external influence to the "market"...needed to ensure an adequate supply of "public" goods that would NOT be produced by the market itself (national defense...pollution control...etc...)
AND...just to make another point...I can graph a shitload more stuff than just supply and demand...there's resource allocation, indifference, marginal outputs, interest rate and fx affects on money, money multipliers...
Only Father Guido Sarducci can get away with all of econ being supply and demand based.
