Demand, Supply and Equilibrium

Aggregate demand and supply means total demand for commodities and total supply of

commodities in an economy respective.

Aggregate supply – relationship between the aggregate quantity of real GDP supplied and the

price level or amount of output the economy can produce given the resources and technology

available.

Aggregate quantity of goods and services supplied is the sum of the quantities of all final goods

and services that all firms in the economy planned to produce.

Position of supply curve depends on the productive capacity of the economy.

Aggregate Demand– relationship between the aggregate quantity of real GDP demanded and

the price level.

The aggregate demand curve shows the level of output at which the goods markets and money

market are simultaneously in equilibrium at each given price level.

The position of the aggregate demand curve depends on monetary and fiscal policy and the

level of consumer confidence.

Macroeconomic issues

Inflation - how quickly prices are raising. High inflation caused to less demand

Unemployment – the fraction of the labour force that is out of work

Macroeconomics measurements – GNP

Income Method

Rentals,Dividends,Depreciation,intrests,etc.

Expenditure Method

𝑌 = 𝐶 + 𝐼 + 𝐺 + 𝑁𝑋

𝑌 = 𝑟𝑒𝑎𝑙 𝐺𝑁𝑃 𝑑𝑒𝑚𝑎𝑛𝑑𝑒𝑑

𝐶 = 𝑐𝑜𝑛𝑠𝑢𝑚𝑝𝑡𝑖𝑜𝑛

𝐼 = 𝐼𝑛𝑣𝑒𝑠𝑡𝑚𝑒𝑛𝑡𝑠

𝐺 = 𝑔𝑜𝑣𝑒𝑟𝑛𝑚𝑒𝑛𝑡 𝑒𝑥𝑝𝑒𝑛𝑑𝑖𝑡𝑢𝑟𝑒

𝑁𝑋 = 𝑁𝑒𝑡 𝐸𝑥𝑝𝑜𝑟𝑡 ( 𝐸𝑥𝑝𝑜𝑟𝑡 – 𝐼𝑚𝑝𝑜𝑟𝑡𝑠)

GDP And GNP

Gross Domestic Product – value of all final goods and services produced in the country within a given

time period.

𝐺𝑁𝑃 = 𝐺𝐷𝑃 + 𝑁𝑒𝑡 𝑓𝑎𝑐𝑡𝑜𝑟 𝑖𝑛𝑐𝑜𝑚𝑒 𝑓𝑟𝑜𝑚 𝑎𝑏𝑟𝑜𝑎𝑑

𝑁𝑒𝑡 𝐷𝑜𝑚𝑒𝑠𝑡𝑖𝑐 𝑃𝑟𝑜𝑑𝑢𝑐𝑡 = 𝐺𝐷𝑃 – 𝐷𝑒𝑝𝑟𝑒𝑐𝑖𝑎𝑡𝑖𝑜𝑛

𝐺𝑁𝑃 𝐷𝑒𝑓𝑙𝑎𝑡𝑜𝑟 = (𝑁𝑜𝑚𝑖𝑛𝑎𝑙 𝐺𝑁𝑃)/(𝑅𝑒𝑎𝑙 𝐺𝑁𝑃)

GNP Deflator – reflects what is happening to the overall level of prices in the economy
