1. draw a diagram to show the long run equilibrium condition of the perfectly competitive firm

2. explain three reasons why monopolies arise

Expert Solution

a) The below diagram shows the equilibrium in the long run in a perfectly competitive market. In the long run, the firm will only be breaking even i.e. no profit and no loss. The production will occur at the lowest point of the LAC (Long run average cost) and at this point, the LMC (Long run marginal cost) and Average revenue will be equal to marginal revenue and price.

2) Three reasons why monopolies arise are:

Economies of scale: A single firm can produce at a lower cost and supply in the whole market efficiently and at a lower cost rather than needing many small different companies to provide the same amount.
Access to raw material or technology: If only one firm in the market has access to the raw material needed for production or the technology needed for the production of goods it will create a monopoly of that firm in the market.
Monopoly by law: Patents, copyright etc create a monopoly in the market of the firm holding the patents. It is created by government law to help the company benefit from its innovation.

Draw graphs showing a perfectly competitive firm and industry in the long-run equilibrium. a. How do you know that the industry is in long-run equilibrium? Long-run when quantity demanded=quantity supplied, no entry and not exit as firms are breaking even. (Which holds true when the P=ATC) b. Suppose that there is an increase in demand for this product. Show and explain the short-run adjustment process for both the firm and the industry. Market demand curve shifts to the right. Equilibrium...

Diagram a purely (product market) competitive firm in long-run equilibrium. Be sure to show both the market and the representative firm. Next, on the same diagram, show what happens to the market and the representative firm if the market demand for the product falls dramatically, for instance, due to bad press. Briefly explain your conclusions. Please show me your thought process. Please explain it as if you are telling it to someone who has no clue about economics.
