A price floor is the minimum price below which a commodity cannot be sold or the minimum wage below which employees cannot be paid. A price floor that is effective in the labor market increases the wages of employees above the market equilibrium price, resulting in increased worker surplus.Before the price floor was implemented, the equilibrium wage was lower than the price floor. This results in the minimum wage being higher than the equilibrium wage, which results in a surplus of employees at this rate and a shortage of employers at this rate.In addition, the employee's surplus, or the difference between the wage paid and the employee's reservation wage, increases. If the price floor is less than the employees' reservation wage, they will not be impacted because their wages are already higher than the minimum wage.The main answer is that an effective price floor in the labor market increases the worker surplus as compared to before the price floor. This is due to the fact that when a price floor is implemented in the labor market, it increases wages above the market equilibrium price, resulting in an increase in worker surplus.The explanation is that, before the price floor, the equilibrium wage was lower than the price floor, resulting in a shortage of employers at the minimum wage and a surplus of employees. However, when the price floor is implemented, the employee's surplus increases, resulting in a higher worker surplus.
