Book excerpt: Demand is one of the few economic terms almost everyone knows. Demand drives supply. When demand rises, it stimulates growth - jobs are created, the economy flourishes and society thrives. So goes the theory. It sounds simple, yet almost no one really understands demand, including the business owners, company leaders and policy makers who try to stimulate and satisfy it. DEMAND is a book with breakout general non-fiction potential which searches for clues as to where demand really comes from, and why, and how we might control it.
