Question

B1 Suppose that you have been hired as an Economic Consultant by OPEC and given the following schedule showing the world demand and supply for oil: (4 marks) Quantity Supplied (Qs) Price (P)Quantity Demanded (QD) S/barrel) (millions of barrels/day)Cmillions of barrels/day) 10 20 30 40 50 60 50 40 30 20 20 30 40 50 60 Answer the following questions a. At what price, the oil market will be in equilibrium situation? b. IfOPEC produces 50 million of barrels/day, calculate its Total Revenue (TR)? c. If the price of oil rises from $40 to $50 per barrel, what will be the Total Revenue (TR) from oil sales? Also mention either TR will increase or decrease? d. When the price changes from $30/barrel to $40/barrel, calculate Price Elasticity of Demand (Ed)?

Explanation / Answer

At $30, the supply = demand

If OPEC produces 50 Million barrels per day, then the demand is 30 million barrels per day. Therefore, total revenue at $40 per barrel is 1200 million per day.

@$40, demand is 30 million barrels per day, total revenue is 1200 million per day

@$50, demand is 20 million barrels per day, total revenue is 1000 million per day

There is a decrease of 200 million in revenue per day
