Economic profit = revenue − (explicit + implicit costs); Accounting profit = revenue− explicit costs only. Economic profit is therefore smaller — and a firm earning zero economic profit is doing exactly as well as its next-best alternative: it earns normal profit (the minimum return that keeps it in the business — itself an implicit cost).2. Normal profit is a cost; supernormal (above-normal) profit invites entry. That single sentence drives the whole theory of markets (3.4).
