Draw a diagram for a perfectly competitive industry with firms earning normalprofits in the long run. Assume that all firms in the industry use oil as key inputs.Using an appropriate diagram, illustrate an increase in the price of inputs. Will firmlevel profits increase or decrease and will market supply increase or decrease?
A perfectly competitive firm can produce its current level of output at an average total cost of $10 and a marginal cost of $8. If the market price of the product is currently $8, what should the firm do? a. The answer depends upon the relationship between price and average variable cost. The firm should shut down if average variable cost is $8 or greater, but the firm should continue to produce the current level of output if average variable cost is less than $8. O b. The firm should definitely shut down since average total cost exceeds price. Oc. The firm should continue to produce, but they should decrease production in order to increase profit. O d. The firm should increase production in order to increase profit. 0= Icon Key mentMain.do?takeAssignmentSessionLocator=assignment-take,53ef7eec-ce82-423c-a5cf-a72630d672e7#

17. A market is in long-run equilibrium and firms in this market have identical cost structures. Suppose demand in this market decreases. a. Describe what happens to the profit-maximizing output quantity for individual firms as the market leaves and then returns to long-run equilibrium. b. Describe what happens to the market quantity as the market leaves and then returns to long-run equilibrium.
1. Assume you have a perfectly competitive market with two types of firms. The only difference between the two types of firms is that the minimum average cost at which firms of type A can produce is lower than the minimum average cost at which firms of type B can produce. a. Give a graphical example of what the individual long run supply functions of a type A firm and a type B firm may look like. Explain the shape in detail. b. Based on your example, what will the aggregate supply curve of a market with 2 firms, one type A and one type B, look like? Explain the shape in detail. C. Assume now that all potential firms are identical. Evaluate the impact of a demand shock on the long run equilibrium market price and firm numbers. You must use graphical analysis and explain in detail.
