If planned investment is equal to actual investment, then aggregate expenditure is equal
to GDP.
Bringing oil to the market is a relatively long and costly process. The whole process
from exploration to pumping significant amounts of oil can take years. What does this
indicate about the price elasticity of supply for oil?
A) The elasticity coefficient is likely to be very high and supply is inelastic.
B) The elasticity coefficient is likely to be close to zero and supply is perfectly elastic.
C) The elasticity coefficient is likely to be low and supply is highly inelastic.
D) The elasticity coefficient is likely to be low and supply is highly elastic.
Scenario 1-3 Suppose a t-shirt manufacturer currently sells 5,000 t-shirts per week and
makes a profit of $10,000 per week. A manager at the plant observes, “Although the last
400 t-shirts we produced and sold increased our revenue by $4,000 and our costs by
$4,800, we are still making an overall profit of $10,000 per week so I think we’re on the
right track. We are producing the optimal number of t-shirts.”
Had the firm not produced and sold the last 400 t-shirts, would its profit be higher or
lower, and if so by how much?
A) Its profit will be $4,800 higher.
B) Its profit will be $800 higher.
C) Its profit will be $800 lower.
