1. What is the average product of four janitors?

2. Is the addition of the third janitor associated with increasing, diminishing, or negative marginal returns? Explain.

3. Is the addition of the fourth janitor associated with increasing, diminishing, or negative marginal returns? Explain.

4. Is the addition of the seventh janitor associated with increasing, diminishing, or negative marginal returns? Explain.

5. Draw the total product, average product, and marginal product curves and shade the regions corresponding to increasing marginal returns, decreasing marginal returns, and negative marginal returns.

6. Calculate the slope of the total product curve as each janitor is added.

1) The average product of four janitors is four classrooms cleaned per evening. 2)The marginal product of the third janitor is greater than that of the second, so the firm is experiencing increasing marginal returns. 3) The marginal product of the fourth janitor is four classrooms cleaned per evening, and the marginal product of the third janitor was five…

srooms cleaned per evening, so the firm is experiencing diminishing marginal returns. 4) The seventh janitor reduces total output, so the firm is experiencing negative marginal returns 6) janitors per evening 1 2 3 4 5 6 7 MPL 3 4 5 4 1 0 -1
