a) $5.
b) $8.
c) $10.
d) none of the above.
Problem 2: A perfectly competitive firm faces:
a) a perfectly elastic demand function.
b) a perfectly inelastic demand function.
c) a demand function with unitary elasticity.
d) none of the above.
Problem 3: For the cost function C(Q) = 100 + 2Q + 2Q^2, the total variable cost of producing 2 units of output is
a) 16.
b) 12.
c) 4.
d) none of the above.
Problem 4: Solutions to the principal-agent problem are intended to ensure that the firm is operating
a) on the production function.
b) above the production function.
c) below the production function.
d) above the isoquant curve.
Problem 5: You are an efficiency expert hired by a manufacturing firm that uses K (capital) and L (Labor) as inputs. The firm produces and sells a given output. If w (wage) = $30, r (cost-of-capital) = $20, MPL = 60, and MPK = 60:
a) the firm is cost minimizing.
b) the firm should use less L and more K to cost minimize.
c) the firm should use more L and less K to cost minimize.
d) the firm is profit maximizing but not cost minimizing.
