The introduction of a minimum wage is an intervention in the market mechanism. This intervention can be considered in two ways: when the government sets it below or above the equilibrium value of wages in the market.
1) If wages below the equilibrium level are established, then it can be argued that this will entail a decrease in labor market supply, as part of the labor force will tend to obtain professions in which labor is paid higher.
2) If wages are above the level of equilibrium, then it can be argued that this will entail an increase in the supply of labor, as part of the labor force.
This situation will also affect the demand for labor, reducing it, as employers can reduce jobs in such a situation.
