01 In which situation is the economy fully replacing old capital and adding more new capital?
Answer and explanation
Correct answer: C. Gross investment is greater than depreciation
Explanation: Depreciation is the amount of existing capital that must be replaced to maintain the capital stock. When gross investment is greater than depreciation, it first covers this replacement and leaves an excess. That excess is positive net investment and expands the capital stock. Equality only maintains the stock, while a smaller gross investment cannot fully replace the depreciated capital.
