The After-School Rush
More buyers arrive, but the original price tag stays up.

Your starting point
Distinguish an audience change from a price change and explain the resulting market balance.
Demand changes when buyers are willing and able to purchase different quantities at each price. Population, income, preferences, expectations, and prices of related goods can matter. The direction depends on the relationship: a cheaper close substitute can reduce demand for the product being studied, while a larger audience may increase it.
A product’s own price change causes movement along its demand schedule in the basic model. To find evidence of a shift, compare old and new quantities at the same price. A statement that sales rose is not enough; more sales could result from a lower price, changed supply, or other conditions.
The fictional snack stand gains a larger after-school audience when a neighboring program relocates. Its production conditions remain unchanged for the controlled comparison. Later rounds examine a competing snack and an incomplete headline. Keep the market definition specific: the price of this stand’s snack and the price of another snack are not interchangeable causes.
