CHAPTER 4 | SUPPLY AND DEMAND
Consider the market for minivans. For each of the events listed below, identify which of the determinants of demand or supply are affected. Also, indicate whether demand or supply increases or decreases and the resulting effect on price and quantity demanded.
1. PEOPLE DECIDE TO HAVE MORE CHILDREN.
Which of the determinants of demand or supply are affected?
One of the determinants of demand that is affected is income because a family deciding to have more children may have received a salary increase which in turn would give the family additional funds to purchase a minivan for their growing family. Another determinant of demand that is affected is the number of buyers because if several families decide to have more children the quantity demanded in the market would be higher at every price, and market demand would increase.
On the other hand, one of the determinants of supply that is affected is expectations because a company may expect the price of the minivans to fall in the near future, that company may decide to put most of its current minivan production into the market for all the family who’s decided to have more children to purchase.
Indicate whether demand or supply increases or decreases.
With what is mentioned above for demand in minivans, the demand curve would shift to the right which means that there would be an increase in demand.
At the same time, the supply curve would shift to the left which means that there would be a decrease in supply because a lot of the families are buying the minivans for their growing family.
Indicate the resulting effect on price and quantity demanded.
Assuming that the statements above are true, the price of the minivan falls while the quantity demanded rises.
2. A STRIKE BY STEELWORKS RAISES STEEL PRICES.
Which of the determinants of demand or supply are affected?
One of the determinants of demand that is affected is expectations because one might expect the steel price to go down in the future, therefore, one would put off on buying a minivan.
On the other hand, one of the determinants of supply that is affected is also expectations because a company may expect the price of steel to fall in the near future, that company may decide to put off production of minivans.
Indicate whether demand or supply increases or decreases.
With what is mentioned above for demand in minivans, the demand curve would shift to the left which means that there would be a decrease in demand.
At the same time, the supply curve would shift to the left which means that there would be a decrease in supply because a company is putting off the production of the minivans.
Indicate the resulting effect on price and quantity demanded.
Assuming that the statements above are true, the price of the minivan rises while the quantity demanded falls.
3. The price of sport utility vehicles rise.
Which of the determinants of demand or supply are affected?
One of the determinants of demand that is affected is the prices of related goods because let’s say that the price of minivans falls, you would buy the minivan instead of the SUV, because the functions minivans are somewhat similar to SUVs.
On the other hand, one of the determinants of supply that is affected is expectations because you may not expect the price of the SUV to fall in the near future, so you decide to purchase the minivan instead.
Indicate whether demand or supply increases or decreases.
With what is mentioned above for demand in minivans, the demand curve would shift to the right which means that there would be an increase in demand.
At the same time, the supply curve would shift to the left which means that there would be a decrease in supply because a lot of individuals are buying the minivans.
Indicate the resulting effect on price and quantity demanded.
Assuming that the statements above are true, the price of the minivan falls while the quantity demanded rises.
4. A stock market crash lowers people's income.
Which of the determinants of demand or supply are affected?
One of the determinants of demand that is affected is number of buyers because with the lowered income, there would be fewer buyers out in the market for minivans.
On the other hand, one of the determinants of supply that is affected is number of sellers because a company may lay off some of their employees resulting of less supply of production of minivans.
Indicate whether demand or supply increases or decreases.
With what is mentioned above for demand in minivans, the demand curve would shift to the left which means that there would be a decrease in demand.
At the same time, the supply curve would shift to the left which means that there would be a decrease in supply.
Indicate the resulting effect on price and quantity demanded.
Assuming that the statements above are true, the price of the minivan rises while the quantity demanded falls.
