- peak
- during the business cycle, the highest point of output before a recession begins
- physical capital
- the plant and equipment used by firms in production; this includes infrastructure
- potential GDP
- the maximum quantity that an economy can produce given full employment of its existing levels of labor, physical capital, technology, and institutions
- production function
