Final answer:
To calculate the economic profit, subtract both explicit and implicit costs from total revenue. In this case, the implicit cost is the $30,000 of foregone rental income for the land. With this deduction, the economic profit can be found for the firm's last year of operation.
Step-by-step explanation:
The calculation of economic profit requires taking into account both explicit and implicit costs. In the scenario provided, where a factory sits on land owned by the firm that could be rented for $30,000 per year, the implicit cost of not renting the land (known as opportunity cost) must be considered in the calculation of economic profit. Assuming the firm has accounted for all other costs and revenues, to calculate economic profit, we subtract both the explicit costs (operational costs, wages, etc.) and the implicit costs ($30,000 of foregone rental income) from the total revenue.
Example Calculation:
Let's say the total revenue reported by the firm last year was $200,000, and the explicit costs (including salaries, materials, and other operational expenses) amounted to $100,000. The economic profit would be:
Total Revenue: $200,000
Minus Explicit Costs: $100,000
Minus Implicit Costs (Opportunity Cost of Land): $30,000
The economic profit would thus be:
- $200,000 - $100,000 - $30,000 = $70,000
