Key Concept

Government Subsidy Impact on Total Expenditure

Explanation

When the government provides a subsidy, it lowers the effective price paid by buyers or increases the price received by sellers. The total subsidy amount is calculated by multiplying the subsidy per unit by the quantity sold. In this case, the subsidy is $3 per unit. To find the total subsidy, we need to determine the equilibrium quantity after the subsidy is applied. However, without additional information on how the subsidy affects supply and demand, we cannot determine the exact changes in buyer expenditure, seller benefit, or buyer benefit. Therefore, we can only confirm the total subsidy amount if we know the quantity sold.
