A decision you can investigate
- A firm replacing worn equipment records investment, yet its productive capital may barely increase. A lower interest rate is useful only if the firm can borrow and expects a worthwhile project.
- Investment means productive spending here, not every purchase called an investment in everyday language.
Build the explanation
- Gross investment 总投资 includes new productive spending that replaces depreciated capital as well as additions. Net investment 净投资 is gross investment minus depreciation, the consumption of fixed capital over the stated period. Investment can respond to economic growth and expected demand, interest rates, business confidence, credit availability and taxes on company profits.
- Growth can raise the need for capacity, but unused equipment or uncertainty may weaken the response. Higher interest raises financing cost and can make future returns less attractive. Tax relief, subsidies and lower corporation tax may increase retained funds or net returns, but do not guarantee additional productive projects. State the incentive and the condition required for a response.
Work through the evidence
- A fictional capital stock begins at 500. Gross investment 90 and depreciation 30 give net investment=90−30=60; closing stock=500+60=560, ignoring revaluation and other changes. If gross investment instead equals depreciation 30, net investment is zero even though replacement spending occurs.
- A fictional loan of 1000 at 5% costs 50 interest per year under simple terms; at 7% it costs 70. A project yielding cash inflow before interest and other relevant costs of 60 would leave 10 after interest at 5% but−10 at 7% in this deliberately simplified comparison. A subsidy 20 to initial capital cost or tax relief affects different parts of the decision; it cannot be assumed to remove every later cost.
What is net investment in the 90/30 case?

Subtract depreciation 30 from gross investment 90.
Test the limits
- This short arithmetic is not a full investment appraisal: lifetime cash flows, risk, repayment, depreciation, taxes, financing terms and alternatives matter. An existing share purchase transfers financial ownership and is not itself new production of a capital good. Investment increases AD now and may increase productive capacity later, but poor targeting or idle capital can weaken that supply effect.
- A tax incentive may reward projects firms would have undertaken anyway. A lower corporation-tax rate can raise retained profit but public revenue and competing spending uses matter. Credit rationing, expectations and implementation lags can dominate the nominal incentive.
What is closing capital stock under the stated exclusions?

Add net investment 60 to opening stock 500.
Buying an existing company share necessarily counts as productive investment I in aggregate demand.

It changes financial ownership; productive investment records new capital formation under the account’s scope.
Apply and explain your answer
- Why can gross investment be positive when net investment is zero?
- The spending may only replace depreciated capital; no net addition remains after the replacement allowance.
Why might a lower borrowing rate fail to raise investment?

The interest channel depends on finance and expected returns.
Use the terms precisely
- gross investment: Productive investment including replacement of depreciated capital.
- net investment: Gross investment less depreciation over the stated period.
