Joey cuts lawns during the summer. Let q equal the number of acres mowed per day, and let L equal the number of hours worked per day. Joey never works more than eight hours per day, and during that time his short-run production function is q = 0.2 * L. Which of the following statements is FALSE? A) Joey's marginal productivity equals his average productivity. B) Joey's marginal productivity diminishes by 0.2 for each additional hour worked. C) Joey's average productivity is constant. D) Joey's marginal productivity is constant

The answer is B.

Explanation:

Marginal Productivity can be described as when every variable in the equation is held constant, it is the amount of productivity gained for every extra hour of labor that is put in.

And according to the information about Joey and his productivity cutting the lawns, we are provided the equation q = 0.2*L which means that for every extra hour Joey works cutting the lawns, Joey's marginal productivity is going to decrease by 0.2 or 20% so the answer is B.

I hope this answer helps.

B) Joey's marginal productivity diminishes by 0.2 for each additional hour worked.

Explanation:

Joey's production function is Q = 0.2 x L

where:

Joey's productivity is constant, so he doesn't show any diminishing marginal productivity. E.g.
