Macroeconomics

Macroeconomics is a branch of economics dealing with the performance, structure, behavior, and decision-making of the whole economy. A book on the subject appeared in "Revenge of the Chip". D.W. believed she would look grown up by just having it with her because it is an enormous book, even though she had no idea what it was about.

Trivia

 * "Macroeconomics" is one word, but it appears to be written as two words on the cover.
