Hello everyone, I'm new to the forum, please excuse me if I've posted in the wrong section. Im currently taking a distance learning course in Microeconomics and need to submit a 1500 word essay on the "main differences between a perfectly competitive market, monopoly, monopolisitcs competition and an oligopoly" I've currently written around 600-700 words about the basic such as high barriers of entry, price changes etc. After this I've decided to write about demand curves and supply curves for each type of market and profit maximisation theories. I'm currently struggling to make sense of everything from my readings and online searches as every website seems to have different version of demand or supply curves and some don't explain at all. Could anyone tell me if I'm on the right track or should I drop the demand/supply curves and is there anything else I could write about for the remainder of the essay? Thanks in advance.
