1. The problem statement, all variables and given/known data A firm produces a single output (q) using Labor (L), and Capital (K). Its technology is described by the cobb-douglas production function Q= 10K and L is in a square root. a. Does this technology exhibit increasing,decreasing, or constant returns to scale? Does it exhibit a diminishing marginal productivity of labor? b. What can you say about the shape of this firm's short-run marginal cost curve? Is it positively sloped, negatively sloped, flat or u-shaped? What can you say about the shape of the long-run averagce cost curve? 2. Relevant equations A relative equation is the Cobb-Douglas is relevant. Q= AK^B(beta) times L^a(alpha) 3. The attempt at a solution What I did since L is in a square root, I raised L(labor) to the 1/2. I then concluded 1/2 was alpha, and if alpha is less that 1 then its MPL was decreasing. But if alpha = 1 then its a constant, and if its greater than 1, than its increasing. But I cant figure how the graphs would look or if I calculated it right. If someone can help I would appreciate it, thanks.
