Consider the market for snow shovels following a severe winter snowstorm.

a. Describe how the storm could simultaneously affect both supply and demand. While there are many possibilities, just describe one set of conditions that would cause changes in both supply and demand.

b. Describe how higher prices of shovels immediately before and/or after a storm serve both an allocative and a rationing role.

c. What does the vertical interpretation of the demand curve teach us? Discuss how the vertical interpretation of the demand curve can help us understand what consumers might do when prices of snow shovels are kept below market clearing levels immediately before and/or after a storm.
