How do you calculate expenditures?
expenditure approach: The total spending on all final goods and services (Consumption goods and services (C) + Gross Investments (I) + Government Purchases (G) + (Exports (X) – Imports (M)) GDP = C + I + G + (X-M). depreciation: The measurement of the decline in value of assets.

How do you calculate aggregate consumption function?
Consumption function definitionYd = disposable income (income after government intervention – e.g. benefits, and taxes)a = autonomous consumption (consumption when income is zero. e.g. even with no income, you may borrow to be able to buy food)b = marginal propensity to consume (the % of extra income that is spent).
What happens when aggregate expenditure is equal to GDP?
If aggregate planned expenditure equals real GDP, the change in firms’ inventories is the planned change. If aggregate planned expenditure exceeds real GDP, firms’ inventories are smaller than planned; if aggregate planned expenditure is less than real GDP, firms’ inventories are larger than planned.
What is an example of a consumption expenditure?
Common examples are cars, furniture, and appliances. Durable goods constitute about 10-15 percent of consumption expenditures. Nondurable Goods: These are tangible goods that tend to last for less than a year. Common examples are clothing, food, and gasoline.
What are the 5 components of GDP?
