1. True False.  All economic decisions can be analyzed with static modeling accurately.

2. True False.  The R/P (reserve over production) ratio gives a measure of how long current proved reserves will last if current production continues.

3. True False.  If an oil R/P ratio = 15, it indicates that the country will certainly run out of oil in 15 years.

4.  True False.  The countries with largest oil and gas reserves are Saudi Arabia, Iraq and Kuwait.

5.  True False. Maximizing the value of production of nonrenewable reserves in a competitive two time period world with no costs can be solved using a Lagrange multiplier method. The solution will show that in a competitive model with no cost, price needs to go up at the interest rate (P1 = (1+r)P0).

6.  True False.  Let demand, P(Q), represents social benefits, R be total reserves of a fixed energy source, r be the interest rate, and marginal costs are zero.  Then price going up at the interest rate maximizes social welfare.

                                                reserves = 100,

                                                income (Y) = 70 and does not grow,

                                                interest rate (r) = 10%,

                                                and MC = 0,

then optimal use of resources over two time periods will be Q0 = 56.67 and Q1 = 43.33 and net present value of reserves = 40,000.

7.  True False. If demand is    Qd = 120 - 1/3 P + Y,

                                                reserves = 100,

                                                income (Y) = 70 and does not grow,

                                                interest rate (r) = 10%,

                                                and MC = 0,

then optimal use of resources over two time periods will be Q0 = 56.67 and Q1 = 43.33 and net present value of reserves = 40,000.

8. True False. In a two period model with fixed reserves, if the interest rate increases, production will be delayed to the second period.

9. True False. In the two period model from above,

            Qd = 120 - 1/3 P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and MC = 0, and

optimal output in each period was Q1 = 43.33 and Q0 = 56.67. 

If reserves, R, change from 100 to 150 for the model, then production will in increase in both period and Q0 = 80.48 and Q1 = 69.52.

10. True False. If income increases the same amount in both periods for a two period model with fixed reserves, production will be increased in both periods, but by a greater amount in the second period. 

11. True False. In a two period model from above,

            Qd = 120 - 1/3 P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and MC = 0, and

optimal output in each period was Q1 = 43.33 and Q0 = 56.67. 

Now let total costs TC = 50Q.  Since marginal costs are constant, optimal output will not change.

12.  True False. In a two period model from above,

            Qd = 120 - 1/3 P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and TC = 50Q, and

optimal output in each period was Q0 = 55.87 and Q1 = 44.13. 

Now if the market is monopolistic instead of competitive, then production will be delayed to the second period and Q0 = 52.14 and Q1 = 47.85.

13.  True False. When the interest rate goes to infinity, you should behave as you would in a static market. 

14. True False. New technologies in several areas of the oil and gas industry are likely to have a great impact on production costs in the near future.

15.  True False. The “rule of capture” encourages efficient use of oil resources and is a good example of well-defined property rights, leading to welfare maximization.

16. True False. A dynamically optimizing competitive private market, with no externalities and  well defined property rights, will produce where social welfare is maximized. 

17. True False. The first order conditions for competitive and monopoly markets with fixed resources are different in both the static and dynamic optimization. 

18.  True False. Bonus bidding is favored by economists because it does not distort the production profile.

19.  True False. Work bidding is used by governments that want to develop their resources at a very slow pace.

20.  True False. The winner’s curse describes the paradox of some resource rich countries that under perform in comparison with some resource poor countries.

21. True False. Concessions and production sharing are two different types of economic agreement between governments and companies that have very different economic impacts.

22. True False. A profit tax (tp = 8%) leaves the optimal use of a resource over two time periods the same.

23. True False. An ad valorem tax on a nonrenewable resource would not change the production profile. 

24. True False. Iraq has the highest proven oil and gas Reserve/Production ratio in the world because they value the future more (P1 >Po(1+r)) than the current period.  (i.e. their current production rate is low because they think that the oil in the ground is worth more than the money in the bank.

25. True False. Governments can unitize an oil field as a way of alleviating a monopolistic market imperfection.

26. True False. In a two period model from above,

            Qd = 120 - (1/3)P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and MC = 0, and

optimal output in each period was Q1 = 43.33 and Q0 = 56.67. 

Now if a backstop is introduced with a backstop price of $350, then production will be Q0 = 83 and Q1 = 73.33 and the amount of backstop consumed in the second period is 56.33.

27. True False. In a dynamic multiperiod model,

            Qd = 120 - 1/3 P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and MC = 0

And reserves would last 5 periods before they were exhausted.

28. True False. Assume that producers dynamically optimize in a two period model from above,

            Qd = 120 - (1/3)P + Y,

            R = 100,

            income (Y) = 70 and does not grow,

            interest rate (r) = 10%,

            and MC = 0, and

optimal output in each period was Q1 = 43.33 and Q0 = 56.67 at price Po = $400 and P1 = $440.  If a price control of $308 is passed, Po = $308 and P1 = $308.
