Formula for aggregate demand
Aggregate demand (AD) is the total planned spending on domestically produced final goods and services in an economy during a given period.
AD = C + I + G + (X − M)
Where:
- AD: Aggregate demand or aggregate expenditure (total planned spending).
- C: Desired consumption expenditure by households.
- I: Desired investment expenditure by firms.
- G: Desired government expenditure on goods and services.
- X: Exports of goods and services (what foreigners buy from us).
- M: Imports of goods and services (what we buy from other countries).
- (X – M): Net exports (exports minus imports).
CISCE: Class 12
Core Idea
- Keynesian theory states that an economy's short-run income depends on aggregate demand (AD), the total planned spending on goods and services.
- Higher AD leads to more sales, increased production, more jobs, and higher national income, regardless of full employment status.
CISCE: Class 12
Planned vs Actual Demand
- Planned demand (ex-ante) is the intended spending by households, firms, government, and foreigners before purchases occur.
- Actual demand (ex-post) is what people really buy; mismatches cause unplanned inventory changes, adjusting actual investment.
- Equilibrium occurs when planned demand equals actual demand, balancing output.
CISCE: Class 12
Components Table
- C (Consumption): Households' planned spending on goods/services like food and clothing, driven by disposable income; example: festival shopping surges.
- I (Investment): Firms' planned spending on capital goods, inventories, or houses, driven by interest rates (lower rates increase I); example: factory expansions.
- G (Government): Planned public spending on infrastructure like roads and schools; example: economic stimulus packages.
- X - M (Net Exports): Exports minus imports, driven by exchange rates and trade policies; example: IT service exports.
CISCE: Class 12
Simple Closed Economy
- In a basic model without trade or government, AD simplifies to C + I.
- Consumption is household spending on goods/services; investment covers capital assets and inventory changes.
CISCE: Class 12
Key Points: Aggregate Demand and Its Components
- AD determines income levels through its four components, each with unique drivers like income for C and rates for I.
- Policy can boost AD by increasing G or lowering interest rates to stimulate growth.
- Understanding planned vs actual demand explains inventory adjustments and equilibrium.
- For exams, memorize the AD formula and one key driver per component.
