1. Why are coal miners paid more than other workers with similar amounts of education? (4 Marks) 2. A basic finding of labour economics is that workers who have more experience in the labour force are paid more than workers who have less experience (holding constant the amount of formal education). Why might this be so? Some studies have also found that experience at the same job (called job tenure) has an extra positive influence on wages. Explain why this might occur.(4 Marks)
