Answer:
All statements are correct.
Explanation:
Derived demand refers to a demand for some production factor that results from the demand of another product or service. The demand for labor results from the demand for the products or services that the company sells. If the company sells more products or services, its demand for labor should increase.
The higher the productivity of labor, less quantity of labor will be demanded. For example, automation increases labor productivity (higher total output with less labor) but also decreases the total number of workers.
If the price of a product or service decreases, the quantity supplied will also decrease, decreasing the demand for labor. If the price increases, the opposite will happen.
The marginal revenue product curve should equal the demand curve for labor in order to maximize profits.
