1. True False. From 1953-1999, there was a growing European dependence on natural gas.

2. True False. From 1953-1999, coal use in Europe increased.

3. True False. The evolution of the European natural gas industry since the end of WW II shows an increasingly interconnected market with a high degree of government participation.

4. True False. Town gas is a form of natural gas produced locally and delivered without a long distance pipeline system

5. True False. In Europe, town gas was increasingly replaced with less expensive natural gas in the 60s

6. True False. Most European countries produce enough natural gas for their own needs.

7. True False. The European Economic Community (EEC) and the European Union (EU) can be used alternatively to describe an alliance of European Nations.

8. True False. In the last two decades European energy policy focused on three main issues:

oil production in the North Sea, imports from middle East, and energy price caps.

9. True False. The European Energy Charter Treaty supports energy reform, encourages technology transfers and promotes environmental goals in former Eastern Bloc countries.

10. True False. From 1973-1983, the use of oil decreased in Europe.

11. True False. The Troll field is a major gas field located in the North Sea.

12. True False. Zeebrugge is a major gas field in Russia, discovered in the mid 90s.

13. True False. The Urengoi gas field in Russia along with eight other gas fields are connected to Europe’s gas markets.

14. True False. Russia has huge gas reserves, equivalent to an 80 years supply of gas at the 1999 rate of production.

15. True False. Small firms dominate the European energy markets.

16. True False. The Cournot model is solved just like a monopoly.

17. True False. A backstop technology is one, which is currently available at a reasonable price.

18. True False. The Stackelberg model is similar to a dominant firm model.

19. True False. Price and total profit in a competitive model is higher than in a Cournot duopoly model.

20. True False. . In a competitive market, the short run supply curve equals the horizontal sum of the marginal cost curves while in a Cournot duopoly model, the duopolists face the same demand and cost functions and they choose the price to maximize profit

21. True False. Suppose that Norway (country 1) and Russia (country 2) are the only two gas exporters to Germany.  The inverse demand function in this market is P = 140 - 0.7(q1 + q2). Where P is price and q1 and q2 are the outputs for firms 1 and 2, respectively.  C1 = 8q1 and C2 = 1.8q. Where C1 and C2 are the total costs for firms 1 and 2. Then using the Stackleberg (price leader) model, the quantities are q1 = 93.33, q2 = 26.67 and the price is, p = 40.

22. True False. In the Stackleberg model, the leader firm chooses its own output level based on how other firms will react, while the follower firm chooses their optimal output based on what the leader produces.  In the dominant firm model one firm or the dominant firm is the price setter and the smaller, fringe firms, are price takers.

23. True False. Assume the demand in a market is P = 1,000 – Sqi where i varies depending on the number of firms in the Cournot market and assume that each firm has the same total cost function equal to 100qi.  The equilibrium price with three firms is lower than it is for two firms.

24. True False. The equilibrium price in a Bertrand duopoly is higher than the equilibrium price in a perfectly competitive market.

25. True False. Suppose Firm 1 and Firm 2 are duopolists for a given market.  The inverse demand function is P = 200 - 2(Q1+Q2), where P is price and Q1 and Q2 are the outputs for Firm 1 and Firm 2, respectively.  Cost functions for the firms are, C1 = 6Q12 and C2 = 5Q2+10. In this market, price equals to 95.66 and profit ratio of the two firms (p2/p1) is 11.

26. True False. Suppose the average total cost function for a backstop (solar energy) technology for Q < 20 is AC = 100/Q, whereas for Q > 20, AC = 5. Demand for the energy market is Q = 60 - 2P and marginal cost function for the monopolist is MC = 0.8Q.  Considering the limit pricing model, profit would be $438 for the monopolist under a threat of possible backstop entry.

27. True False. In a bilateral monopoly, the reservation price of the supplier results in zero producer surplus.

28. True False. We expect that price in a bilateral monopoly would be between the reservation price of the buyer and the supplier. 

29. True False. A perfectly price discriminating monopolist would produce the same amount as  would be produced in a competitive market and there will no dead-weight loss from the monopoly power, because the marginal revenue and demand curves of the perfectly price discriminating monopolist are identical. 

30. True False. . A perfectly price discriminating monopolist faces a demand curve of P = 50 – 0.25Q and a marginal cost of MC = 2.5Q.  The profit maximizing quantity = 18.18 and price = $45.45, and the profit of the monopolist = 454.56.

31. True False. As fossil fuels are depleted, we expect to move on to lower cost renewable fuels.
