I recently become interested in finance. Many books discuss options as simple examples of derivatives. I also read some "popular books". I read in "The Poker Face of Wall Street" that almost no farmers actually use commodity exchanges (p91), while in many places the opposite is claimed (for example, "Traders, Guns, & Money", p 25, says "The major users [of commodity futures] were really farmers"). Why are these two accounts differ?
