Suppose the current price of oil is $90 a barrel and the quantity supplied is 800 million barrels per day
If the price elasticity of supply for oil in the short run is estimated at 0.5, use the midpoint formula to calculate the percentage change in quantity supplied when the price of oil rises to $98 a barrel.
The percentage change in quantity supplied = [(98 - 90 ) / (98 + 90 ) / 2] × 0.5 × 100 = (8 / 94 ) × 0.5 × 100 = 4.26 percent.
