Use graphs and a brief explanation to answer the following.
Answer : 1) As corn is the input of ethanol production, hence if price rise for corn then ethanol production cost increase. As production cost increases for ethanol hence the production level decreases. For this reason the supply curve of ethanol shift to leftward. As a result, at new equilibrium the price level increase for ethanol. This situation is shown by the following picture's diagram.
In the above diagram E is the
initial equilibrium point. After decreasing the production of
ethanol the new equilibrium point is E1. At E1 equilibrium point
the price level of ethanol increases from P to P1.
2) In case of substitute goods if price of one good increase then demand decrease for that good but demand increase for another good. Due to increase in demand for good the demand curve shift to rightward. As a result, at new equilibrium the quantity level increase. This situation is shown by the following picture's diagram.
In the above diagram E is the
initial equilibrium point for paper made from timber. Due to
increase in price for substitute good recycled paper the demand for
recycled paper decrease but the demand for paper made from timber
increase. After increasing demand for paper made from timber the
new equilibrium point is E1. At E1 equilibrium point the quantity
level increases from Q to Q1.
3) In case of inelastic demand if price rise then total revenue increase and if price fall then total revenue decrease. Here the demand for gasoline is inelastic. In this situation if supply of gasoline increase then the price level decrease. As a result, the total revenue decrease. This situation is shown by the following picture's diagram.
