In the short run, we assume that capital is a fixed input and labor is a variable input, so the firm can increase output only by increasing the amount of labor it uses. In the short-run, the firm's production function is q equals f (Upper L comma Upper K )overbar, where q is output, L is workers, and Upper K overbar is the fixed number of units of capital. A specific equation for the production function is given by: q equals 8 KL plus 5 Upper L squared minus (one third )Upper L cubed . or , when Upper K overbar = 22, q equals (8 times 22 times Upper L )plus 5 Upper L squared minus (one third )Upper L cubed . The level of output q for 10 units of labor input is nothing (enter your response rounded up to two decimal places). The average productivity of these 10 units of labor is nothing (enter your response rounded up to two decimal places). The marginal productivity of using one more unit of labor input is nothing (enter your response rounded up to two decimal places). Given the relationship between the average productivity and the marginal productivity, the average productivity of labor is ▼ falling a maximum rising .
