In a perfectly competitive market, state the condition (clearly) that causes firms to enter the market? When does the entry and exit of firms from the perfectly competitive industry end? (micro economic question)write it in your own words :)

Ok so, the condition that causes firms to enter the market is when firms are making Super Normal Profit. This is when Average Total cost curve is under the MR=D=AR=P line. So firms outside the market are attracted to the SNP being made, and the profits get competed out until normal profit is being made. That’s when ATC is equal to MR=D=AR=P line. If more people enter the market, that’s when a loss is being made.

Wite quickly without over thinking .
