To determine which two factors would result in a change in the market for Movie Theater Popcorn, we need to consider both supply and demand dynamics.
-
New advertisements for a Marvel movie results in a significant increase in people attending the movies in person.
- This would likely lead to an increase in demand for popcorn as more people attending the theater would mean more people purchasing snacks like popcorn. (This would result in a shift in demand.)
-
The price of movie theater candy, a substitute for popcorn, dramatically increases.
- If the price of a substitute good (in this case, movie theater candy) increases, consumers may choose to purchase more popcorn instead, leading to an increase in demand for popcorn. (This would also result in a shift in demand.)
The other two options can be analyzed as follows:
-
Prices of movies dramatically increase following a strike by the actor's union.
- This could potentially decrease demand for going to the movies, possibly reducing demand for popcorn as well.
-
A devastating tornado wipes out the corn crops in the Midwest.
- This would affect the supply of popcorn, likely leading to a decrease in supply and potentially increasing prices.
Based on the analysis above, the two factors that would likely result in a change in the demand for Movie Theater Popcorn are:
- New advertisements for a Marvel movie results in a significant increase in people attending the movies in person.
- The price of movie theater candy, a substitute for popcorn, dramatically increases.
