In the first four chapters, in Part One, there is an overview of basic economic concepts. In the last chapter of this part, the workings of markets is explained in great detail. It is essential for everybody who studies economics to understand how the forces of supply and demand interact in markets.
Part Two introduces the three most important variables in macroeconomics: GPD, inflation, and unemployment, which are used in later chapters to construct models to represent different theories about how the economy works.
