Simultaneously, the local bakery raises the price of its croissants from $2 to $3. Based on the principles in the note, explain how the demand graph for croissants would be affected by (a) the influx of new residents and (b) the price increase.\n* **Answer:** \n  * (a) The influx of new residents represents a change in **population**, which would cause a **shift of the whole demand curve**. \n  * (b) The price increase from $2 to $3 would cause a **movement along the demand curve**, resulting in a fall in the quantity demanded. \n\n**Question 4 (Comprehension/Recall)**\nIf a student claims that a change in consumer tastes will cause a \"movement along the demand curve,\" why are they incorrect based on the rules provided?\n* **Answer:** They are incorrect because a movement along the curve is only caused by a change in price.
