The purpose of this section is to provide students with the opportunity for a detailed examination of the major macroeconomic issues facing countries’ economic growth, economic development, unemployment, inflation, and income distribution.
Section 4 deals with external equilibrium. Income distribution is introduced here in section 3 but is addressed in greater detail in section 5.
The economic strategies available to governments such as demand-side policies, supply-side policies, and direct intervention are introduced and evaluated. These policies are applicable to almost all areas of macroeconomics, international economics and development economics.
