As m approaches q, the wage a worker requires to exert effort goes to infinity and employment approaches zero. In the limit, any wage that ensures that no firm wants to hire a worker will be an equilibrium wage. Any wage that is at least as high as F (0) will do. Intuitively, as m approaches q, the expected benefit of being diligent - relatively more time spent in employment - gets smaller and smaller for a given wage. In order to induce a worker to exert effort, the firm needs to make the time spent in employment increasingly more attractive, leading to exploding wages
