shifts in supply and demand curves

 Using shifts in supply and demand curves, describe a change in the industry in which your firm operates. The change may arise from a change in costs, entry/exit of firms, a change in consumer tastes, a change in the Macroeconomy, a change in interest rates, or a change in exchange rates. Label the axes, and state the geographic, product, and time dimensions of the demand and supply curves you are drawing. Explain what happened to industry price and quantity by making specific references to the demand and supply curves. If more than one change occurred, then decompose the change into smaller pieces so that your explanation has a step-by-step character to it. (Hint and warning: Demand and supply curves are used at the industry level, not at the firm level.) Describe how your company could profitably use the analysis.   2. Snack food vendors and beer distributors earn some monopoly profits in their local markets but see them slowly erode from various new substitutes. When California voted on legalizing marijuana, which side would you think that California beer distributors were on? What about snack food venders? Why?
