In the pursuit for cost minimization to produce quantity Q, at what point does the firm achieve optimality?Question 9Select one:a.Any combination of K and L is optimal.b.By solely focusing on the isocost line.c.Where the isoquant and isocost line cross paths.d.At the maximum level of output achievable with a given cost.

A profit-maximising firm in a monopolistic competition setup will seek to produce the quantity Q where (X), and charge the price indicated by the firm’s (Y) curve at quantity Q. Identify X and Y.X = marginal cost equals marginal revenue; Y = marginal cost X = average cost is more than average revenue; Y = average total cost X = marginal cost equals marginal revenue; Y = demand X = average cost is more than average revenue; Y = demand

The point of tangency between an isocost line and an isoquant is necessarilyGroup of answer choicesthe profit-maximizing combination of inputs that should be hired to produce that output level.the least costly combination of inputs that can be hired to produce the output level.both the profit-maximizing and least costly combination of inputs that can be used to produce the output level.the minimum amount of output that can be attained for that level of expenditure.

At the efficient scale of production,Group of answer choicesmarginal cost must be at a minimum.marginal cost must be rising.marginal cost should be falling.marginal cost must be constant.

A.2 For a monopolist having a capacity level k:i. It is always optimal to fix a price for which the quantity sold is equal to k.ii. It is never optimal to fix a price for which quantity sold is equal to k.X The optimal price may imply a quantity sold equal to k.iv. The optimal quantity always implies marginal revenue equal to marginal cost.
