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 is increased or decreased. Then show the effect on the price and quantity of minivans.
a. People decide to have more children.
b. A strike by steelworkers raises steel prices.
c. Engineers develop new automated machinery for the production of minivans.
d. The price of SUVs rises.
e. A stock market crash lowers people’s wealth.
a). People decide to have more children :
The demand for minivans will increase, so the demand curve will shift to the right. Though there will be no change in the supply curve. There will also be a rise in Price and Quantity.
The graph is shown below :
b). A strike by steelworkers raises steel Price :
The production cost of minivan will increase which will cause the supply of minivans to reduce. Demand will not be affected. As a result, the price of minivans will increase and there will be a decline in the quantity sold.
The Graph is shown below :
c). Engineers develop new automated machinery for the
production of minivans :
Since engineers have done an improvement in technology, which will
eventually reduce the total cost in the product manufacturing, it
will result in an increase in supply. Again the demand will be un
affected and there will be a decline in price and increase in
quantity.
As shown below in the graph :
d). The price of sports utility vehicles rises
:
Minivans are substitutes of sports utility vehicles. If there is a rise in the price of sport utility vehicles, the demand for minivans will Increase. Supply will not be affected. As a result the price and quantity of minivans will rise.
The graph is shown below :
e). A stock market crash lowers people's wealth
:
As stock market crash is affecting people's wealth and eventually their income, it will lead to a decrease in demand for minivans. Supply is not affected. As a result, both the equilibrium price and the equilibrium quantity decline.
The graph is shown below :
