The document outlines topics to review for an economics class on Monday, including a quiz from Friday and homework due. It will discuss where demand curves come from, what causes shifts in curves using an application of oil speculators, and how shifts in the curves change the equilibrium price and can create shortages or surpluses. The key concepts are that quantity responds to price, with many buyers and sellers setting the price, and that buyers and sellers are price-takers rather than price-makers.
