Circular Flow of the Economy

  • Developed by François Quesnay in 1758, depicting interactions in a market economy through production and consumption.

Models of Circular Flow

First Model

  • Describes a simple economy where households and business firms are the same entity.
  • Production value equals income; household demand drives firm supply.

Second Model

  • Distinguishes households and business firms.
  • Households provide production factors; firms create products using these resources.
  • Two Markets:
    • Factor Markets: Households supply factors.
    • Commodity Markets: Firms sell finished goods to households.

Third Model

  • Considers future decisions of both sectors; households save/reinvest income.
  • Investment is spending by business firms using savings.

Fourth Model

  • Government's role includes implementing laws and collecting taxes.
  • Taxes fund public services that stabilize the economy.

Fifth Model

  • Represents an open economy with external sectors engaged in international trade.
  • Trade manages imports and exports to balance resource needs.
  • Local products gain international exposure; foreign products address domestic shortages.
