Demand


The basic tool that economist use to analyze how changes in economic events, e.g., raising the drinking age, increasing the gasoline tax, affect the market for the impacted good or service. Each market is comprised of both producers, those offering (supplying) the good, and consumers, those who buy (demand) the good. These tutorials should assist you in better understanding Demand.
