| isida | III and IV are wrong because for perfectly competitive markets, demand = MR = price which is straight line; it can never incerase |
| bluefin209 | I'm pretty sure that demand can increase in a perfectly competitive market. It certainly can decrease, giving rise to the problem of when a firm should shut down. I disagree with this answer. |
| sunny | Well, the increased demand won't necessarily attract new entries, as current players in the market may increase supply. As long as there are positive economic profits, even if the demand is decreasing, there will be new entrants to the market to take advantage of the economic profits. Keep in mind that all these are in the long-run. |
| AlexYuen | the only reason why this ans makes sense are the keywords 'as long as' i.e they are looking for the single most impt factor. in LR or SR, all other ans (except iv) are plausible too (note qn: ENTRY to perfect comp. mkt) |
| cmisaac | the question starts "in the long run ..." |
| jerylewis | as long as Price exceeds ATC right? not AVC? |
| bobert | in response to cmisaac, you do not enter an industry in the short-run. Not enough time. In response to jerylewis, yes because the way you said it, you would be earning economic profit and therefore firms enter to get a piece of it. II is wrong because it is not the motivator to enter the market. It is a given that there are no barriers, but they enter to get economic profit, and leave if they are suffering economic losses until it balances out at normal profit. With regards to III, when demand increases, it shifts the industry demand curve to the right, prices move up, and quantity increases (as described in this lesson) but there is never economic profit to be had. Remember, in the LONG RUN, ECONOMIC PROFIT is the motivator for entering into the industry. Otherwise there are break even profits (normal profits) or economic losses, in which case firms will be exiting. |
| bidisha | thanks bobert |
| gill15 | Q9 of this section relates to this. From that demand can increase so Isida is wrong. But Q9 also says that if demand increases economic profit does happen and firms enter which makes sense to me. I dont understand why III is wrong here. Goto question 9 and come back here. Im confused |
| gill15 | Read my previous post. Think I got it now. Demand will cause P to increase which THEN will result in Economic Profit and therefor entry will occur just like Q9 says BUT this is not a condition that can continue forever into the future - demand can not just keep increasing. |
| dmfz | If there is incentive in the market because market is profitable, it will drive new firms to enter the market. |
| linzlinked | How can firms make economic profit in perfectly competitively market? Shouldn't be 0? |
I just wanted to share the good news that I passed CFA Level I!!! Thank you for your help - I think the online question bank helped cut the clutter and made a positive difference.
