"Employers think at the margin when they decide how many extra workers to hire. "
From the above wet site.
Thinking at the margin means considering the additional or incremental costs and benefits of a decision. It involves evaluating the advantages and disadvantages of making a small, incremental change in a current situation. In the example of hiring a new worker, you would need to weigh the potential benefits that the new worker may bring, such as increased productivity or expanded services, against the costs involved in terms of salary, training, and other resources. By considering these factors, you can make an informed decision about whether the benefits outweigh the costs and if hiring the new worker is a good idea.
