Bread | Cheese | Pizza | |
Costs of Input | $0 | $0 |
$50 bread $35 cheese |
Wages | $15 | $20 | $75 |
Value of Output | $50 | $35 | $200 |
Question 24. Calculate GDP the following three ways (note there is a missing line in the above chart):
A. As value added
B. As spending on final goods and services
C. As factor income (the companies have no rent or interest payments)
(A) As Value Added -
Value added by bread = Value of output - Cost of input = $50 - $0 = $50
Value added by cheese = Value of output - Cost of input = $35 - $0 = $35
Value added by pizza = Value of output - Cost of input = $200 - $85 = $115
Calculate GDP -
GDP = Value added by bread + Value added by cheese + Value added by pizza
GDP = $50 + $35 + $115 = $200
So,
The GDP as value added is $200.
(B) As spending on final goods and services
The final good is pizza. The pizza is sold for $200.
So,
The GDP as spending on final goods and services is $200.
(c) As factor income
Total wages = $15 + $20 + $75 = $110
Profit from bread = Value of output - Cost of input - Wages = $50 - $0 - $15 = $35
Profit from cheese = Value of output - Cost of input - Wages = $35 - $0 - $20 = $15
Profit from pizza = Value of output - Cost of input - Wages = $200 - $85 - $75 = $40
Total profit = $35 + $15 + $40 = $90
GDP = Total wages + Total profit = $110 + $90 = $200
So,
The GDP as factor income is $200.
