Profit maximization is one of the pillars of economic theory, explaining how companies seek to achieve a high level of profit to maximize their wealth and benefits, just as individuals do with their level of utility.
This concept is especially important in the microeconomic study, as it is a pillar of multiple economic models. This happens because maximizing the wealth or welfare level is a basic principle that companies follow when facing a certain economic activity.
