ASSUMPTIONS, CLASSICAL ECONOMICS: Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.

Lesson 15: Aggregate Market | Unit 2: Equilibrium
|
Page: 9 of 22
|
The dynamic nature of the aggregate market makes the long-run equilibrium a moving target.- The difference between long-run and short-run equilibria is critical to the study of the macroeconomy.
- Aggregate demand, especially investment, is volatile.
- Aggregate supply, although somewhat predictable, involves continuous adjustments.
- Long-run equilibrium is a perpetually pursued goal, but seldom actually reached.
As we approach the long-run equilibrium target, it has likely changed due to different economic conditions, due to changes in aggregate demand, aggregate supply, or more than likely, both.

PAYMENT FLOW In the circular flow, the transfer of money in payment in exchange for the counter-clockwise physical flow of goods and services. The payment flow is the monetary payment for goods and services received by the household sector from the business sector through product markets and the monetary payment for resource services obtained by the business sector from the household sector through resource markets. The payment flow is usually illustrated as a clockwise flow for a model with the product markets at the top, resource markets at the bottom, household sector at the left, and business sector at the left. The physical flow moves in the opposite direction.
