LEARNING OBJECTIVES

To understand the meaning

and mother nature of mixture demand.

To derive/sketch an aggregate

demand curve intuitively.

To understand the determinants

of the aggregate demand curve.

Aggregate demand (AD) is the

total level of costs on

services and goods in an economic climate

by people, firms, government

and the overseas sector.

AD = C + We + G + By - M

consumption

expense

government spending

exports

imports

DERIVATION OF

THE AGGREGATE

DEMAND CURVE

Imagine the general cost

level declines, ceteris paribus.

THREE things will happen…

" other things continue to be the same”

If the standard price level falls…

• Lower prices provide households better liquidity

(consumers will have more cash to spend).

• Less cash will need to be borrowed.

• Interest rates will show up, thus stimulating

greater usage and expense.

• As well, with affordable prices, the home-based country's

foreign competitiveness will increase

(cheaper exports). Demand for export products will rise.

AD = C & I + G & X - M

If the basic price level falls…

Precisely what are the

determinants of

the aggregate

demand contour?

CONSUMPTION

• Consumption is a expenditure of households

about final services and goods. It is the

most significant component of combination demand.

• There are several factors that will affect

consumption, and hence affect nationwide output

(expenditure method) and aggregate demand.

• As national income soars, it is an signal

that the economy's performance can be improving.

• Households may feel certain about long term

prospects. Consequently , consumption is going to rise.

• Ceteris paribus, aggregate demand will go up.

The ADVERTISEMENT curve is going to shift seite an seite to the proper.

General price level (P)

When Sumado a increases, ceteris

increase, hence the AD

shape shifts seite an seite to

the proper from 𝐴𝐷0 to 𝐴𝐷1.

(2) Age framework of population

• The younger the population, the higher the

degrees of consumption, nevertheless not guaranteed.

• An aging human population tends to have lower

intake levels seeing that people are investing in

retirement and future medical needs.

• Elderly people are definitely more careful about all their

spending given that they have retired (no income).

(3) Likes, preferences, standards of living
