Answer and Explanation:
Movement along the demand curve in the labor market occurs when there is any change in wages of labor. An increase in wage rate will lead to decrease in quantity of labor demanded. As a result, demand curve will move upwards and vice versa.
Reasons other that increase or decrease in price such as demand for the respective product, will lead to shift in demand curve. For example, an increase in the demand for a particular good will increase the demand for labor that will produce the product. An increase in demand for labor in this case will shift the demand curve rightwards and vice versa.
