ok

because in a perfectly competitive firm, P= MR the profiting maximum for perfectly competitive firms is when Price = MC and also MR = MC

ok

providing customers with good products at a low price is probably the best way to ensure success

ok

when revenue increases because of a lower price, causing an increase in amount sold "one good thing" from a price drop

output effect

only _______________ competition can result in productive and allocative efficiency

perfect

when price is reduced and it causes loss in revenue due to total purchases decreasing total revenue, even if more products are sold one "bad thing" of a price change

price effect

A firm's ability to differentiate its product and to produce it at a lower average cost than competing firms creates __________ for its customers.

value

if a firm is about to shut down, as long as _________ price is higher than _____________ (same) cost, it should stay working
