Microeconomics looks at the smaller picture and focuses more on basic theories of supply and demand and how individual businesses decide how much of something to produce and how much to charge for it. People who have any desire to start their own business or who want to learn the rationale behind the pricing of particular products and services would be more interested in this area.
