Question
Suppose that the world price of oil is roughly
​$100.00
per barrel and that the world demand and total world supply of oil equal 34 billion barrels per year​ (bb/yr), with a competitive supply of 20​ bb/yr and 14​ bb/yr from OPEC. Statistical studies have shown that the
short−run
price elasticity of demand for oil is
−0.05​,
and the
short−run
competitive price elasticity of supply is
0.10.
Using this​ information, derive linear demand and competitive supply curves for oil.
Let the demand curve be of the general form
Q=a−bP
and the competitive supply curve be of the general form
Q=c+​dP,
where​ a, b,​ c, and d are constants.
 
The equation for the
short−run
demand curve is?
The equation for the
short−run
competitive supply curve is
