The long-run supply curve of a perfectly competitive industry with increasing costs is: a) Perfectly inelastic b) With positive slope c) Perfectly elastic d) With negative slope

in a perfectly competitive market with a constant cost industry, there are currently 100 identical firms, each with the total cost function TC(Q) = Q^2 + 4Q + 36. The market demand is Q = 1800 – 50p. a. What is the price at the short-run equilibrium? What is the net profit/loss of each firm at this price? b. In the long run, how many firms will enter into /exit from the market?

Answer multiple choice

a) In this industry, what is the short run shut-down price? b) What is the short run supply function at the typical Vietnamese restaurant? c) Sum across restaurants and find the short-run market supply of Vietnamese meals in NYC

The supply curve for a competitive firm is: a)it’s entire MC curve b)the upward-sloping portion of its MC curve c)it’s MC curve above the minimum point of the AVC curve d)it’s MC curve above the minimum point of the ATC curve e)it’s MR curve

A perfectly competitive firm will be operating at its shutdown point if it operates at the minimum point on its ________ cost curve. a )     average total b )     marginal c )     total d )     average variable

Consider the following short-run cost curves for a perfectly competitive firm. Picture is attched  If the current market price is $6, the profit-maximizing output for this firm is ____________ If the price is $6 and the firm is producing at its profit-maximizing output, then total costs for the firm are ______________ If the market price is $1, the firm will produce ______________units of output in the short run. If the price is $3 and the firm is producing at its profit-maximizing output, then the firm would make _________ profit.

A firm operates in a perfectly competitive market. The firm’s total cost of production is given by the following equation: TC(q) = 100 + 48q2 + 5q, where q is the quantity supplied. What is the shutdown point for this firm in the short run, or in other words, what is the market price below which a firm is better off not supplying any units in the short run? [Advice: draw AVC and MC]

Which of the following is true about a perfectly competitive firm in the long run and in the short run? The supply curve in the short run is usually steeper than the supply curve in the long run. The demand curve in the short run is usually steeper than the marginal cost curve in the long run.   The supply curve in the short run is usually steeper than the average total cost curve in the long run.   The supply curve in the short run is usually flatter than the supply curve in the long run.

In a perfectly competitive market, a single firm that sets its price a small amount above the market price will do which of the following? a.Not sell any units at all b.Have lower revenues but receive zero economic profits c.Make lower profits than other firms, but the exact amount less depends on the elasticity of demand for the product d.Earn profits higher than other firms as long as the other firms continued to charge the market price
