Question

Quizplus · Accepted Answer

An increase in the income of buyers of running shoes would lead to an increase in demand for running shoes, which would cause the demand curve to shift to the right. A fall in the price of running shoes would not necessarily cause a shift in the demand curve, as this would just cause a movement along the existing curve. An increase in the price of running shoes would cause a decrease in demand, which would shift the curve to the left. An increase in the supply of running shoes would also cause a shift to the right, but this is not a likely explanation for a shift in the demand curve.
