As MRTS = MPL / MPK
Now as MRTS < PL/PK
MPL / MPK < PL / PK
Thus MPL / PL < MPK / PK
So firm should hire more capital & less Labor, which results in rising MPL & falling MPK
till the MPL/ PL = MPK / PK
Which is the eqm profit maximization condition
now when MRTS not equals input price ratio, then firm is not maximizing the profit,
bcoz when MPL/PL < MPK/ PK
then for every additional dollar spending on production input, marginal productivity of Labor is lower than that of the capital , hence employ more K & less L

Suppose a firm’s production function is well-behaved and strictly convex. Additionally, suppose the firm is operating at some point where |T RS(L, K)| < pL/pK, where “|h|” indicates absolute value of some number h. Explain how this firm can increase its output without changing its total expenditure on inputs. Provide an additional argument for why a firm operating at a point where |T RS(L, K)| 6= pL/pK is not maximizing profit.
Suppose that a firm is operating at a point of its expansion path where MRTSL,K< pL/pK . Explain how this firm can increase its output without changing its total expenditure on inputs. Use this to give an additional argument for why a firm operating off its expansion path would want to more toward its expansion path.
Suppose the firm's production function is given by f(L,K) = 5LK. C represents the total cost of production; the price of L is PL and the price of K is PK. Plot an isoquant from this specific production function. Using graphical analysis derive the firm's conditional demand curve for L in both the short and long run. Explain.
Consider a firm using two inputs; capital (K) and labor (L) in production. The firm's production technology is characterized by the following production function: Q = F(K, L) = 40K L In the short run (SR), the quantity of the capital (K) that the firm uses is fixed at K = 10 whereas the quantity of the labor input can be varied. Price of labor is $4,000 per worker and the price of capital is $2,000 per capital. (PL=$4,000 and...
Question 4 (1 point) Suppose a firm has a production function given by Q = 2K + L, where Lis labor, Kis capital and Q is the quantity of output. Which of the following statements is WRONG? The firm is exhibiting constant returns to scale The firm's marginal product of capital is constant The firm's marginal product of labor is constant The firm's marginal rate of technical substitution depends on the amount of inputs
7. Suppose a firm's production function is Q-min(L,K). (This means the level of O produced is the smaller of L and K) a. Graph some isoquants for this firm. b. Let w = 2, r= 1, and suppose the firm's expenditures are C-12. What are the firm's demands for L and K? What is the share of labor in the cost of output? c. Now let w rise to 3. What are the firm's new demands for L and K?...
Suppose a firm's production function is given by the equation Q = 12L.5K.5 . This firm operates in the short run where capital (K) is fixed at a quantity of 16. If the price per unit of the good is $1.8 and labor costs $10 per unit. Then the profit maximizing amount of labor in the short run is ___?
1. Suppose that a firm's production function of output Q is a function of only two inputs, labor (L) and capital (K) and can be written Q = 25LK. Letting the wage rate for labor be w and the rental rate of capital be r, the equation for the firm's demand for capital would be: wQ A) K = 25r B) K = C) K- 25r wQ rQ 25w 25w rQ 25wQ D) E) KE
