"This Chicago-style approach, sometimes known as ‘Price Theory’ because of the fundamental role that prices often play, is exemplified in the path-breaking work of Gary Becker, Ronald Coase, Milton Friedman, Sherwin Rosen, George Stigler, and many others. Price theory has shed light not only on the most fundamental topics of traditional economics (e.g. consumption, saving, taxation, regulation), but also pioneered the use of economic tools in studying a wide range of other human behavior (e.g. crime and corruption, discrimination, marriage)."
