    What is the answer to the question: Can you name five examples of perfectly competitive markets? Why or why not. My understanding is that there is no such thing as a perfectly competitive market. We may get close to one, such as in the airline industry. But it is still not a perfectly competitive market. Therefore, we can't give five examples. Or, is the question asking for a "nearly" perfectly competitive market. What is being asked for here and am is my understanding correct?

      Perfect competition and why it matters (article) | Khan Academy (4)

      I think mining cryptocurrency meets the criteria listed above in that:

      Many firms (miners) produce identical products (cryptocurrency).
      Many buyers are available to buy the product (cryptocurrency), and many sellers are available to sell the product (cryptocurrency).
      Sellers and buyers have all relevant information to make rational decisions about the product (cryptocurrency) being bought and sold.
      Firms (miners) can enter and leave the market without any restrictions—in other words, there is free entry and exit into and out of the market.

      arguably this isn't the case for every cryptocurrency but it seems like the concept fits nicely.

    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? In this question how can I explain the how small ?

    Suppose, in a perfectly competitive market selling oranges, a seller sells at 4$ per kilo and another seller sells at 5.5$ per kilo. Now, a buyer who comes across these two sellers may think that the 5.5$ oranges are better in quality even though they're the same and may purchase the latter. By going through the fourth paragraph of the 'Perfect competition and why it matters', how can we relate to it and won't other factors like consumer psychology have a say in this?

      If the quality of the good is different based on the supplier (or even if people think that is the case), then it is by definition not a perfectly competitive market. Perfect competition requires completely identical goods. The situation you describe would be a monopolistically competitive market where goods are slightly differentiated.

      In the long run, other firms will enter the market seeking to make the same economic profit. This drives the price down until no firms have any incentive to enter because there are no economic profits.

      Neither. A perfectly competitive market would have no differentiation or their goods or services, which may be accurate if you were talking about a public school, and its definitely not a monopoly as there is not just one brand of private schooling, but more than one. To be honest, based on the detailed characteristics, I'd label it under a monopolistic competition(MC) or an oligopoly. If it were to be under an MC, the main criteria would be similar but differentiated goods or services, and privates schools differ from one another based on their name (their brand). However, in a not-so urban region where private schooling is not common, it may fall under an oligopoly, as it would be one of very few other organisations that provite private schooling services, possibly allowing it a decent amount of market power to be a price maker.

      There's no such thing as completely perfect competition in real life. You need to examine the industry and ask yourself what are the characteristics of perfectly competitive markets and how closely does the cellphone industry match those.

    Is it fair to say that in a perfectly competitive market, the supply is very inelastic? Because even a slight price increase from one firm will lead to them losing all their business to the other firms.

      No, it is actually the opposite: a firm's supply curve is perfectly elastic. Even a slight change in price loses ALL business. Perfectly inelastic would mean a change in price results in NO business lost.

    Does an inelastic demand curve cause farm prices to fluctuate more in response to supply changes than if the demand were elastic?
