Explain in detail how purely competitive markets, in the long-run, know how to adjust to and provide the correct output, at the correct price.
Give an example of a good or service you might buy that is closest to being in a purely competitive market. Explain your logic.
you've been learning about what makes a market perfectly competitive, how a firm in a perfectly competitive market makes profit-maximizing decisions, and how a perfectly competitive market moves towards equilibirium. But how applicable is this to real life?
For this discussion, try to think of a market (for a product or service) that is perfectly competitive or very close to it. What characteristics of the market make it like perfect competition? Are there factors that keep it from being perfectly competitive? If so, what are they? How close do you think the firms in this market are to perfectly competitive firms in choosing equilibrium price and quantity?

- A single firm in a perfectly competitive market is relatively small compared to the rest of the market. What does this mean? How “small” is “small”?arrow_forwardWe expect that firms in perfectly competitive markets can earn higher economic profits in the short run but will only earn normal profit in the long run. Why do we expect perfectly competitive firms to be unable to earn high economic profit in the long run? The inability of perfectly competitive firms to earn high economic profit in the long run is dependent on there being low barriers to entry in perfectly competitive markets. Explain why this is the case. Why do firms remain in business if they cannot earn economic profit?arrow_forwardExplain how economics make profit or loss when firms are perfectly competitive.arrow_forward
