Which of the following factors most significantly influences the supply of labor in a market that offers extensive fringe benefits?

The supply of labor in a market that offers extensive fringe benefits is significantly influenced by the attractiveness of those benefits. When a company provides perks like health insurance, retirement plans, or paid time off, it makes the job more appealing to potential workers. This means that more people are likely to apply for the job, increasing the supply of labor. For example, if a tech company offers generous health benefits, it may attract more software engineers than a company that does not offer such perks. Therefore, the better the fringe benefits, the more workers will want to join the company, boosting the overall labor supply.
