What is the difference between planned and unplanned investment?
In equilibrium, planned spending must equal actual spending in the economy. The difference between planned and actual expenditure is unplanned inventory investment. When firms sell less of their product than planned, stocks of inventories rise.
What is unplanned inventory investment?
Unplanned inventory investment occurs when actual sales are more or less than businesses expected, leading to unplanned changes in inventories.
How do you calculate unplanned and planned investments?
To calculate a business’ unplanned inventory investment, subtract the inventory you need from the inventory you have. If the resulting unplanned inventory investment is greater than zero, then the business has more inventory than it needs.
What causes unplanned investment?
Businesses invest in inventory today to sell in the future. … This change results in an unplanned inventory investment. Businesses can invest more than they initially planned if growth is stronger than anticipated, or if costs are lower than anticipated.
What is negative unplanned investment?
Negative unplanned inventory means you have too little — for example, because sales went faster than expected. You can determine the amount of unplanned inventory by subtracting your planned inventory from total investment; if you have a negative unplanned inventory, the resulting figure will be negative.
What happens when planned saving is less than planned investment?
When planned savings is less than the planned investment , then the planned inventory rises above the desired level which denotes that the consumption is the economy was less then the expected level which indicates at less aggregate demand in comparison to aggregate supply.
What happens when planned saving is more than planned investment?
When planned savings is more than planned investment, then the planned inventory would fall below the desired level. To bring back the Inventory at the desired level, the producers expand the output. … Rise in output means rise in planned investment and rise in income means rise in planned savings.
What is the level of planned investment?

The Multiplier Effect Formula (‘k’)
MPC – Marginal Propensity to Consume – The marginal propensity to consume (MPC) is the increase in consumer spending due to an increase in income. This can be expressed as ∆C/∆Y, which is a change in consumption over the change in income.
What will be the effect of positive unplanned investment?

What is Keynesian cross model?
The expenditure-output model, sometimes also called the Keynesian cross diagram, determines the equilibrium level of real GDP by the point where the total or aggregate expenditures in the economy are equal to the amount of output produced. … A vertical line shows potential GDP where full employment occurs.
What is AE curve?
Aggregate expenditure is the current value of all the finished goods and services in the economy. The equation for aggregate expenditure is: AE = C + I + G + NX. The aggregate expenditure equals the sum of the household consumption (C), investments (I), government spending (G), and net exports (NX).
How do you calculate consumption?
The consumption function is calculated by first multiplying the marginal propensity to consume by disposable income. The resulting product is then added to autonomous consumption to get total spending.
