edit In aggressive and arguable markets
Only in the abbreviate run can a close in a altogether aggressive bazaar accomplish an bread-and-butter profit.
Economic accumulation does not action in absolute antagonism in continued run equilibrium; if it did, there would be an allurement for fresh firms to access the industry, aided by a abridgement of barriers to access until there was no best any profit.2 As fresh firms access the industry, they access the accumulation of the artefact accessible in the market, and these fresh firms are affected to allegation a lower bulk to attract consumers to shop for the added accumulation these fresh firms are bartering (they attempt for customers).4567 Bounden firms aural the industry face accident their absolute barter to the fresh firms entering the industry, and are accordingly affected to lower their prices to bout the lower prices set by the fresh firms. Fresh firms will abide to access the industry until the bulk of the artefact is bargain to the point that it is the aforementioned as the boilerplate bulk of bearing the product, and all of the bread-and-butter accumulation disappears.45 Back this happens, bread-and-butter agents alfresco of the industry acquisition no advantage to entering the industry, accumulation of the artefact stops increasing, and the bulk answerable for the artefact stabilizes.456
The aforementioned is additionally accurate of the continued run equilibria of monopolistically aggressive industries and, added generally, any bazaar which is captivated to be contestable. Normally, a close that introduces a differentiated artefact can initially defended bazaar ability for a abbreviate while. At this stage, the antecedent bulk the customer allegation pay for the artefact is high, and the address for, as able-bodied as the accessible of the artefact in the market, will be limited. In the continued run, however, back the advantage of the artefact is able-bodied established, and because there are few barriers to entry.456 The cardinal of firms that aftermath this artefact will access until the accessible accumulation of the artefact eventually becomes almost large, the bulk of the artefact shrinks bottomward to the akin of the boilerplate bulk of bearing the product. Back this assuredly occurs, all cartel associated with bearing and affairs the artefact disappears, and the antecedent cartel turns into a aggressive industry.456 In the case of arguable markets, the aeon is generally concluded with the abandonment of the aloft "hit and run" entrants to the market, abiding the industry to its antecedent state, aloof with a lower bulk and no bread-and-butter accumulation for the bounden firms.
Profit can, however, action in aggressive and arguable markets in the abbreviate run, as firms jostle for bazaar position. Once accident is accounted for, abiding bread-and-butter accumulation in a aggressive bazaar is appropriately beheld as the aftereffect of connected cost-cutting and achievement advance advanced of industry competitors, acceptance costs to be beneath the market-set price.
edit In uncompetitive markets
A monopolist can set a bulk in balance of costs, authoritative an bread-and-butter accumulation (shaded). The aloft Picture shows a Monopolist (only 1 Close in the Industry/Market). An Cartel usually has "Economic Profit" also, but usually faces an Industry/Market with added than aloof 1 Close (they allegation allotment accessible Address at the Bazaar Price).
Economic accumulation is, however, abundant added accustomed in uncompetitive markets such as in a absolute cartel or cartel situation. In these scenarios, alone firms accept some aspect of bazaar power: Though monopolists are accountable by customer demand, they are not bulk takers, but instead either price-setters or abundance setters. This allows the close to set a bulk which is college than that which would be begin in a agnate but added aggressive industry, acceptance them bread-and-butter accumulation in both the continued and abbreviate run.45
The actuality of bread-and-butter profits depends on the prevalence of barriers to entry: these stop added firms from entering into the industry and arduous abroad profits,7 like they would in a added aggressive market. In cases area barriers are present, but added than one firm, firms can coact to absolute production, thereby akin accumulation in adjustment to ensure the bulk of the artefact charcoal aerial abundant to ensure all of the firms in the industry accomplish an bread-and-butter profit.478
However, some economists, for instance Steve Keen, altercate that alike an atomic bulk of bazaar ability can acquiesce a close to aftermath a accumulation and that the absence of bread-and-butter accumulation in an industry, or alike alone that some assembly occurs at a loss, in and of itself constitutes a barrier to entry.
In a single-goods case, a absolute bread-and-butter accumulation happens back the firm's boilerplate bulk is beneath than the bulk of the artefact or account at the profit-maximizing output. The bread-and-butter accumulation is according to the abundance of achievement assorted by the aberration amid the boilerplate bulk and the price.
edit Government intervention
Often, governments will try to arbitrate in uncompetitive markets to accomplish them added competitive. Antitrust (US) or antagonism (elsewhere) laws were created to anticipate able firms from appliance their bread-and-butter ability to artificially actualize the barriers to access they allegation to assure their bread-and-butter profits.567 This includes the use of bloodthirsty appraisement against abate competitors.478 For example, in the United States, Microsoft Corporation was initially bedevilled of breaking Anti-Trust Law and agreeable in anti-competitive behavior in adjustment to anatomy one such barrier in United States v. Microsoft; afterwards a acknowledged address on abstruse grounds, Microsoft agreed to a adjustment with the Department of Justice in which they were faced with acrimonious blank procedures and absolute requirements9 advised to anticipate this bloodthirsty behaviour. With lower barriers, fresh firms can access the bazaar again, authoritative the continued run calm abundant added like that of a aggressive industry, with no bread-and-butter accumulation for firms.
In a adapted industry, the government examines firms' bordering bulk anatomy and allows them to allegation a bulk that is no greater than this bordering cost. This does not necessarily ensure aught Bread-and-butter accumulation for the firm, but eliminates a "Pure Monopoly" Profit.
If a government feels it is abstract to accept a aggressive bazaar - such as in the case of a accustomed cartel - it will sometimes try to adapt the absolute uncompetitive bazaar by authoritative the bulk firms allegation for their product.56 For example, the old AT&T (regulated) monopoly, which existed afore the courts ordered its breakup, had to get government approval to accession its prices. The government advised the monopoly's costs, and bent whether or not the cartel should be able accession its bulk and if the government acquainted that the bulk did not absolve a college price, it alone the monopoly's appliance for a college price. Though a adapted close will not accept a bread-and-butter accumulation as ample as it would be in an able situation, it can still can accomplish profits able-bodied aloft a aggressive close has in a absolutely aggressive market.6
