Explain the price elasticity of supply for the following cases:?
a. An increase in snowfall in Alberta this winter leads to a huge jump in the selling price of snow blowers.
b. The price of a kilowatt of electricity in Ontario is the same during periods of high electricity demand as during periods of low electricity demand.
c. Fewer people want to fly during November than during any other month. The airlines cancel about 10 percent of their flights as ticket prices fall about 20 percent during this month.
d. Owners of vacation homes in Sandbanks rent out their homes during the summer. Due to the soft economy this year, a 30 percent decline in the price of a vacation rental leads more than half of homeowners to occupy their vacation homes themselves during the summer.
