In the market for wireless earbuds​ (a normal​ good), indicate whether the following events would cause an​ "increase or a decrease in demand​"

or an​ "increase or a decrease in the quantity demanded.​"
Part 2
a. There is an increase in the price of carry cases for wireless earbuds.
Part 3
A.
decrease in demand.
B.
increase in demand.
C.
decrease in quantity demanded.
D.
increase in quantity demanded.

Part 2b. There is an increase in the price of carry cases for wireless earbuds.

This would likely cause a decrease in demand for wireless earbuds.

Equilibrium quantity would

Equilibrium quantity would not be directly affected by an increase in the price of carry cases for wireless earbuds. Equilibrium quantity is determined by the intersection of supply and demand curves, and changes in the price of carry cases would only affect demand. Therefore, the equilibrium quantity would remain unchanged unless there are other factors in the market that change supply or demand.

it either increase or decrease

Apologies for the confusion. You are correct, an increase or decrease in the price of carry cases for wireless earbuds can affect the equilibrium quantity.

If the price of carry cases increases, it could potentially decrease demand for wireless earbuds, leading to a decrease in the equilibrium quantity. On the other hand, if the price of carry cases decreases, it could increase demand for wireless earbuds, resulting in an increase in the equilibrium quantity.

Therefore, an increase or decrease in the price of carry cases can potentially impact the equilibrium quantity of wireless earbuds.

Equilibrium price would increase or decrease

Apologies for the earlier confusion. If there is an increase in the price of carry cases for wireless earbuds, it is likely to have no direct effect on the equilibrium price of the earbuds themselves. The equilibrium price is determined by the intersection of supply and demand curves for wireless earbuds, and changes in the price of carry cases would only affect the demand for earbuds.

However, if the increase in the price of carry cases decreases the demand for wireless earbuds, it could potentially lead to a decrease in the equilibrium price. Conversely, if the increase in the price of carry cases does not significantly impact demand for earbuds, there may be no change in the equilibrium price.

Therefore, the impact of an increase in the price of carry cases on the equilibrium price of wireless earbuds is dependent on the magnitude of the change in demand resulting from the price increase.

b. There is a decrease in the price of devices used to charge wireless earbuds.

Part 6
A.
decrease in quantity demanded.
B.
increase in quantity demanded.
C.
increase in demand.
D.
decrease in demand.

Part 6b. There is a decrease in the price of devices used to charge wireless earbuds.

This would likely lead to an increase in the quantity demanded of wireless earbuds.

wrong answer.

A change in a​ good's own price leads to a change in quantity demanded for any given demand​ curve, other things held constant. A change in any of the ceteris paribus conditions for demand leads to a change in demand which results in a movement​ (shift) of the curve. In this​ case, the​ good's own price did not change.
