Question

question 7 10 pts in the market for cell phones, which of the following causes a shift of the demand curve to the left? studies show that cell phone use causes brain cancer. the price of a cell phone decreases. there is a decrease in the quantity demanded of cell phones. there is an increase in services provided by a cell phone, such as text messaging.

Explanation:

A shift of the demand curve to the left is caused by a non - price factor that decreases demand. If studies show that cell phone use causes brain cancer, consumers will be less willing to buy cell phones at every price level, leading to a left - ward shift of the demand curve. An increase in services provided is not a demand - decreasing factor. A decrease in quantity demanded is a movement along the demand curve, not a shift. A decrease in price causes a movement along the demand curve, not a shift.

Answer:

Studies show that cell phone use causes brain cancer.
