Answer: The answer is provided below
Explanation:
a. An increase in the number of cars will lead to an increase in demand as more people will demand for gasoline. This will lead to a rightward shift of the demand curve from D1 to D2. The increase in demand will also lead to the rise in price of gasoline from P1 to P2.
b. When the economy moves into a recession, people will purchase less cars because of the recession, as the income level of the consumers will have fallen. Due to the decrease in the number of cars, the demand for gasoline also reduces. This is denoted by the leftward shift in the demand curve in the attached diagram from D1 to D2.
c. The increase in the price of car insurance, taxes, maintenance will also lead to a reduction in the demand for cars which will in turn, reduce the demand for gasoline. Thereby the demand curve shifts from from D1 to D2 leftward.
d. The expectations of substantial increase in the price of gasoline, will lead to a higher demand for gasoline in the present period because due to the expectation of a higher price, the consumers will go and buy more gasoline and keep for future use. As the demand for gasoline rises, this will lead to the demand curve for gasoline to shift rightward and also the price will increase from P1 to P2.
