Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
Which feature most distinguishes forestry from most other enterprises?
C. A very long production period
Rotations of decades make the time value of money and risk central to forestry economics.
What is the present value of 5000 received in 30 years, discounted at 5%?
C. 1156.89
PV = 5000 / 1.05^30 = 5000 / 4.3219 = 1156.89. Compounding instead gives 21609.71; simple-interest discounting, 5000 / (1 + 0.05 × 30), gives 2000.00; discounting for one year only gives 4761.90.
Planting costs 1000 now and yields a single revenue of 3000 in 20 years. What is the NPV at 6%?
A. -64.59
PV of revenue = 3000 / 1.06^20 = 935.41; NPV = 935.41 − 1000 = -64.59. 2000.00 ignores discounting; 935.41 omits the cost; −207.14 is the future value at year 20.
Logs sell for 80 per m³ delivered to the mill. Logging costs 20, haulage 15, and the buyer's profit and risk allowance is 10% of the delivered price. What is the stumpage by the residual method?
C. 37 per m³
Stumpage = 80 − 20 − 15 − 8 = 37. Omitting the profit allowance gives 45; 29 takes 10% of the price twice.
When enough buyers compete, the usual way public forest agencies discover stumpage is:
A. Competitive bidding by auction or sealed tender
Competition reveals what buyers will pay; residual appraisals set reserve prices.
The demand for timber is described as derived because it depends on:
B. Demand for the products made from it
Housing, paper, furniture and energy demand drive timber demand.
The value people place on knowing that a rare forest species exists, even if they never see it, is:
A. Existence value
Existence value is a non-use value; bequest value is the value of leaving it to future generations.
Economic cost-benefit analysis differs from financial analysis mainly in that it:
D. Uses society's perspective, shadow prices and externalities
Economic analysis values resources at opportunity cost, excludes transfers and includes externalities.
Payments for ecosystem services are best described as:
C. Voluntary payments from beneficiaries to land managers, conditional on the service
Wunder's definition stresses a voluntary transaction, a well-defined service, buyers and providers, and conditionality.
REDD+ is a mechanism to:
D. Reducing emissions from deforestation and degradation, plus stock enhancement
REDD+ links payments to verified reductions in forest emissions at national or project scale.
