INDUSTRY: A group of firms producing goods or services that are close substitutes-in-consumption. The similarity of the products makes it possible to analyze the production in a market framework. An industry can be broadly defined, such as the manufacturing industry, or narrowly specified, such as the root beer industry. For most economic analysis the term industry is used interchangeably with the term market.

Lesson 10: Gross Domestic Product | Unit 3: Two Views of GDP Page: 15 of 25

Topic: Expenditures <=PAGE BACK | PAGE NEXT=>

The four sectors of the economy buy ALL current economic production and when aggregated give us GDP.

The four sectors and their expenditures:

  1. Household: Consumption (C).
  2. Business: Investment (I).
  3. Government: Government Expenditures (G).
  4. Foreign: Net Exports (X-M), the difference between Exports (X) and Imports (I).
Expenditures on GDP: GDP = C + I + G + (X-M)
  • C, I and G buy not just domestic goods and services, but also imports.
  • When we aggregate C, I, G and X we have domestic production plus imports. To measure only domestic production, we subtract imports (M).
