cbb1 | MRP = marginal product of a resource (e.g. 1 labor hour produces 2 units) mulitplied by the marginal revenue generated by the 2 units. Why is it the price of the output and not marginal revenue of the output in the answer? Marginal revenue could be lower than the price of the 2 units if you had to lower prices on all units to sell the last 2 units. Any explanation? |
wollogo | I agree, this answer is for VMP (Value of Marginal Product) not MRP (Marginal Revenue Product). VMP=MRP only in a price taker situtatio where MR=AR. |
h1bvisa | yes you should assume it's a competitive market if not given. The price should not change at all. |
Lamkerst | MRP=MP*MR I have barely understood the meaning of B. |
Chebum | A and C wrong = B ir right. Only way I got it. |
ddrmax | A could only be right under perfect competition, where P = MR |
robbiecow | MRP = dTR/dX, where X is the input (e.g., worker) TR = Output x Price, rearrange the above d(Output x Price)/dX, rearrange to (dOutput/dX) x (dPrice/dX), note that the second part doesn't change; therefore, it is just the unit price of the output (e.g., I charge $1 for lollipops regardless of my workers) (dOutput/dX) = MP Therefore the equation become MP x Price of my good = MRP |
