If MC>MR, the firm should produce 0 zero. 0 fewer than this quantity. 0 at this quantity. 0 more than this quantity. When you derive the marginal product of labor curve, you use 0 the vertical distance from the production function to the horizontal axis. 0 the slope of the ray out of the origin to the production function. 0 the slope of the production function. 0 the horizontal distance from the production function to the vertical axis. The marginal product of labor is O the output produced by a worker of average quality. 0 total output divided by total labor. 0 the change in output that results from an increase of labor by one unit. 0 the percentage change in output divided by the percentage change in labor. The source of the benefits of the division of labor is O the fact that anytime you increase labor you get more output. that when each worker is equally capable, each worker adds to production exactly the same as the previous one. 0 the efficiency that results from workers specializing in one aspect of production. 0 the inefficiency that results from the fact that capital is fixed
