Final answer:
To compute missing amounts in a contribution income statement, one must subtract explicit costs from revenues to get the accounting profit and calculate the merchandise and current account balances using data on goods, services, and income payments.
Step-by-step explanation:
To compute the missing amounts in the contribution income statement, we use the information provided to fill in Table 9.2, Table 23.2, or Table 10.2, depending on the data given. The merchandise balance is calculated by taking the total value of goods exported and subtracting the total value of goods imported. To find the current account balance, we consider not only the merchandise balance but also the services balance, income payments, and unilateral transfers.
For the case where revenues are $200,000 and explicit costs are $85,000, the accounting profit is determined by subtracting explicit costs from the revenues:
Accounting Profit Calculation
Revenues: $200,000
- Explicit costs: $85,000
= Accounting profit: $115,000
If additional data were provided, we would calculate the missing amounts by placing the known values in the appropriate sections of the income statement and then performing the necessary calculations to find the unknown values.
