Theory

"A monopoly granted either to an individual or to a trading company has the same effect as a secret in trade or manufactures. The monopolists, by keeping the market constantly understocked, by never fully supplying the effectual demand, sell their commodities much above the natural price, and raise their emoluments, whether they consist in wages or profit, greatly above their natural rate...

Theory

Restraints were judged as permissible or not by courts as new cases appeared and in the light of changing business circumstances. Hence the courts found specific categories of agreement, specific clauses, to fall foul of their doctrine on economic fairness, and they did not contrive an overarching conception of market power. Earlier theorists like Adam Smith rejected any monopoly power on this basis.

Theory

The classical perspective on competition was that certain agreements and business practice could be an unreasonable restraint on the individual liberty of tradespeople to carry on their livelihoods.

Under the doctrine of laissez-faire, antitrust is seen as unnecessary as competition is viewed as a longterm dynamic process where firms compete against each other for market dominance. In some markets a firm may successfully dominate, but it is because of superior skill or innovativeness. However, according to laissez-faire theorists, when it tries to raise prices to take advantage of its monopoly position it creates profitable opportunities for others to compete. A process of creative destruction begins which erodes the monopoly. Therefore, government should not try to break up monopoly but should allow the market to work.

International Enforcement

It is unclear whether competition policy is a sensible role for government in developing, particularly low-income countries. In these countries the markets are usually very small and fragmented so that developing scale sufficient to raise competitiveness and engage in international markets is a major challenge. The bigger problem is however poor governance - in societies with widespread corruption, inadequate public finances, and weak judiciary and oversight institutions, competition policy may become another tool for capture by vested interests - becoming in itself a barrier to entry.

Despite that, at the ongoing Doha round of trade talks for the World Trade Organisation, discussion includes the prospect of competition law enforcement moving up to a global level. While it is incapable of enforcement itself, the newly established International Competition Network (ICN) is a way for national authorities to coordinate their own enforcement activities.

Chapter 5 of the post war Havana Charter contained an Antitrust code but this was never incorporated into the WTO's forerunner, the General Agreement on Tariffs and Trade 1947. Office of Fair Trading Director and Professor Richard Whish wrote sceptically that it "seems unlikely at the current stage of its development that the WTO will metamorphose into a global competition authority.
