Study Notes
Fixed Prices and Expenditure Plans
- In the Keynesian model, firms set fixed prices and sell quantities based on customer demand.
- Persistent sales beyond planned levels lead firms to increase prices; low sales result in price reductions.
- Consequently, the overall economy experiences:
- A fixed price level.
- Aggregate demand driving real GDP.
Components of Aggregate Expenditure
- Aggregate expenditure comprises four main components:
- Consumption expenditure
- Investment
- Government expenditure on goods and services
- Net exports (exports minus imports)
- Aggregate planned expenditure is the sum of the planned levels of these components.
Real GDP and Aggregate Expenditure Relationship
- There exists a two-way relationship between aggregate expenditure and real GDP:
- An increase in real GDP boosts aggregate expenditure.
- An increase in aggregate expenditure raises real GDP.
Consumption and Saving Plans
- Key factors influencing consumption expenditure and saving:
- Disposable income
- Real interest rates
- Wealth
- Expected future income
- Disposable income is calculated as aggregate income minus taxes plus transfer payments, linking it directly to real GDP.
Consumption Function
- The consumption function illustrates the relationship between consumption expenditure and disposable income.
- Planned consumption plus planned saving equals disposable income.
- As disposable income increases, consumption expenditure also rises.
Autonomous and Induced Consumption
- Autonomous consumption occurs at zero disposable income, representing short-term consumption behavior.
- Induced consumption increases with disposable income, reflecting consumer spending driven by income levels.
Graphical Representation
- The consumption function can be represented graphically, with the y-axis indicating consumption expenditure and the x-axis showing disposable income.
- A 45° line on the graph indicates points where consumption expenditure equals disposable income:
- Points below the 45° line indicate consumption exceeding disposable income.
- Points above the 45° line indicate consumption below disposable income.
