Question 1

During the 1973-1974 Arab OPEC oil embargo, what happened to the equilibrium price and quantity in the crude oil market, and which curve shifted?

Accepted Answer

Equilibrium price increased, equilibrium quantity decreased; supply curve shifted left. $$S \rightarrow S'$$

Question 2

Suppose a new technological breakthrough makes oil extraction much cheaper worldwide. What is the most likely effect on the oil market?

Accepted Answer

Supply shifts right, equilibrium price falls, equilibrium quantity rises. $$S_0$$ \rightarrow $$S_1$$

Question 3

During the Chinese economic boom of the early 2000s, what happened in the global oil market?

Accepted Answer

Demand shifted right, causing both equilibrium price and quantity to increase. $$D_0$$ \rightarrow $$D_1$$

Question 4

If the supply of oil is very inelastic in the short run, what is the effect of a sudden increase in demand?

Accepted Answer

A large increase in price and a small increase in quantity. $$\Delta P \gg \Delta Q$$

Question 5

After the 1986 Saudi increase in oil output, what was the effect on the oil market?

Accepted Answer

Supply shifted right, equilibrium price decreased, equilibrium quantity increased. $$S_0$$ \rightarrow $$S_1$$

Question 6

Which of the following best describes the effect of Western demand management policies (such as fuel efficiency standards) in the late 1970s and early 1980s?

Accepted Answer

Demand shifted left, causing both equilibrium price and quantity to decrease. $$D_0$$ \rightarrow $$D_1$$

Question 7

Suppose a financial crisis in Asia reduces industrial activity. What is the likely effect on the global oil market?

Accepted Answer

Demand shifts left, equilibrium price and quantity both decrease. $$D_0$$ \rightarrow $$D_1$$

Question 8

If both supply and demand for oil become more elastic in the long run, what is the effect of a demand shock compared to the short run?

Accepted Answer

The price change is smaller and the quantity change is larger in the long run. $$|\Delta P_{LR}|  |\Delta Q_{SR}|$$

Question 9

Which of the following scenarios would most likely cause a leftward shift in the oil supply curve?

Accepted Answer

A major war in a key oil-producing region disrupts production. $$S_0$$ \rightarrow $$S_1 ($$left)

Question 10

If the oil market is initially in equilibrium and a new environmental regulation reduces oil demand, what happens to the equilibrium price and quantity?

Accepted Answer

Both equilibrium price and quantity decrease. $$P_1$$ \u003c $$P_0$$, $$Q_1$$ \u003c $$Q_0$$

Question 11

Suppose the short-run supply of oil is perfectly inelastic ($$S_{SR} is $$vertical). If demand increases, what happens to the equilibrium price and quantity?

Accepted Answer

Equilibrium price increases, equilibrium quantity does not change. $$\Delta Q = 0$$

Question 12

Which of the following best explains why oil prices spiked during the Iranian Revolution and the Iran-Iraq War?

Accepted Answer

Supply of oil shifted left due to production disruptions. $$S_0$$ \rightarrow $$S_1 ($$left)

Question 13

If the long-run supply of oil is more elastic than the short-run supply, what does this imply about the oil market's adjustment to a persistent increase in demand?

Accepted Answer

In the long run, the price increase will be smaller and the quantity increase larger than in the short run. $$|\Delta P_{LR}|  |\Delta Q_{SR}|$$

Question 14

Which of the following best describes the concept of 'peak oil' as discussed in the context of oil market history?

Accepted Answer

The point at which global oil production reaches its maximum rate, after which production will decline.

Question 15

If a government unexpectedly releases large amounts of oil from its strategic reserves, what is the likely short-run effect on the oil market?

Accepted Answer

Supply shifts right, causing equilibrium price to fall and quantity to rise. $$S_0$$ \rightarrow $$S_1 ($$right)

Question 16

Which of the following is a plausible reason why oil demand is more elastic in the long run than in the short run?

Accepted Answer

Consumers and firms have more time to adjust their behavior and technology, such as switching to fuel-efficient vehicles.

Question 17

Suppose a new major oil field is discovered and developed, and at the same time, a global recession reduces demand for oil. What is the likely effect on equilibrium price and quantity?

Accepted Answer

Equilibrium price will decrease, but the effect on quantity is ambiguous without more information.

Question 18

If oil supply is perfectly elastic in the long run, what happens to the equilibrium price and quantity when demand increases?

Accepted Answer

Equilibrium price remains unchanged, equilibrium quantity increases. $$\Delta P = 0, \Delta Q \u003e 0$$
