The market demand curve for labor is downward sloping. It reflects the value of the marginal product of labor.
When the price of the product changes, it shifts the market demand curve for labor.
Consider a hypothetical market where a single type of water purifier is sold by numerous firms for the same price. Here, consumers are becoming increasingly aware of the health benefits of clean drinking water. This may increase the demand for water purifiers, leading to higher product prices.
The increase in price means that the value of the marginal product of labor or VMPL becomes larger. This is because the VMPL is the marginal product of labor multiplied by the price of the water purifiers.
It becomes more profitable to hire workers as additional workers help to earn greater revenue.
So, the demand for labor by all the firms manufacturing water purifiers increases, shifting the market demand curve for labor to the right.
A decrease in the price of water purifiers will decrease the demand for labor by the firms. This will shift the market demand curve for labor to the left.
A shift in the market demand for labor occurs when the total number of workers employers wish to hire changes at every wage level, due to factors othe…
