A) Product Approach
GDP = Value added of all industries
Value added = revenue - intermediate costs
Value added coconut producer = $20,000,000 (it does not have intermediate costs)
Value added restaurant = $30,000,000 - $12,000,000 (cost of coconuts)
= $18,000,000
Value added government = $5,500,000 (collected in taxes, $3 million from the restaurant, $1.5 million from the coconut producer, and $1 million from consumers).
GDP = $20,000,000 + $18,000,000 + $5,500,000
= $43,000,000
B) Expenditure Approach
GDP = Consumption + Investment + Government Spending + Net Exports
Consumption = $8,000,000 in coconuts + $30,000,000 in meals
= $38,000,000
Investment = $0
Government Spending = $5,500,000 in government wages
Net Exports = $0 (it is a closed-economy)
GDP = $38,000,000 + $0 + $5,500,000 + $0
= $43,500,000
C) Income Approach
Wages = $14,500,000
Corporate Profits = $24,000,000
Interest income = $500,000
Taxes = $4,500,000
GDP = $43,500,000
e. How does this new piece of information affect your calculations in the expenditure approach? Explain.
GDP under the expenditure approach, would rise by the value of the unsold coconuts ($1 million) as long as the coconuts were harvested in the given year. This is because inventory produced in the given year, is part of that year's GDP.
