Final answer:
To determine the company's earnings, accounting earnings are calculated by subtracting the original purchase costs from the appraised sale values, resulting in $18 million when all properties are sold. There are no earnings when no properties are sold. If only the depreciated or appreciated properties are sold, the earnings are -$11 million and $29 million, respectively.
Step-by-step explanation:
To calculate the accounting earnings and economic earnings for the real estate investment company in the given scenarios, we will follow two fundamental steps. Firstly, we identify the total revenues and secondly, we deduct the explicit and implicit costs, where applicable, to determine both types of earnings.
Scenario a: Selling All Properties
Accounting Earnings = (5 × $9.4 million) + (5 × $17.4 million) - (10 × $11.6 million)
= $47 million + $87 million - $116 million
= $18 million
Economic Earnings = Accounting Earnings (As there are no additional implicit costs to consider)
= $18 million
Scenario b: Selling No Properties
Since the company sells none of the properties, there are no revenues obtained from sales, hence, Accounting Earnings = $0.
Economic Earnings also equal $0 assuming there are no implicit costs or benefits.
Scenario c: Selling Properties that have Fallen in Value
Accounting Earnings = (5 × $9.4 million) - (5 × $11.6 million)
= $47 million - $58 million
= -$11 million (Accounting Loss)
Economic Earnings = Accounting Earnings
= -$11 million
Scenario d: Selling Properties that have Risen in Value
Accounting Earnings = (5 × $17.4 million) - (5 × $11.6 million)
= $87 million - $58 million
= $29 million
Economic Earnings = Accounting Earnings
= $29 million
