New Zealand has decriminalised cartels. Price fixers cannot be sent to prison but can still be fined. Some agree, some disagree with the wisdom of this move.

Those that agreed with the wisdom of this move were christened cartel apologists by one of those that disagree with the removal of criminal penalties for cartels.

There is an infallible rule in competition law enforcement. It arises mostly crisply in merger law enforcement. If competitors oppose a merger, the merger must be pro-consumer. If the merger is anti-competitive, that merger will increase prices. The competing firms can follow those prices up and profit from the weakening of competition.

Under the collusion hypothesis, rivals of the merging firm benefit since there is a higher probability of successful collusion limits output and raises product prices. The share prices of these rival firms should increase in anticipation of enhanced cartel profits. As Eckbo explains:

Using Stigler (1964) theory of oligopoly, a horizontal merger can reduce the monitoring costs by reducing the number of independent producers in the industry. The fewer the members of the industry the more “visible” are each producers actions, and the higher is the probability of detecting members who try to cheat on the cartel by increasing output.

When was the last time an entrepreneur complained about his rivals putting their prices up? The entrepreneur can either match that price increase or undercut it to win more business. The real reason competitors oppose a merger is the merged firm will have lower costs, making it a fiercer competitor.

If the share prices of competitors fall on news of the merger, they are worse off as a result because they face a fiercer competitor. If their share prices rise, that suggests either that others in the industry are to  benefit from higher prices or rival firms will soon replicate the cost savings discovered in the course of the merger. The latter is the information effect of mergers:

…since the production technologies of close competitors are (by definition) closely related, the news of a proposed efficient merger can also signal opportunities for the rivals to increase their productivity

Mergers are a high-risk way of securing higher prices unless there are offsetting cost saving of combining the two firms. Mergers disturb previously efficient firm sizes and risk diseconomies of scale and a burgeoning corporate hierarchy. A cartel is a safer way to raise prices by jointly agreeing to restrict output.

Cartels have few redeeming features. Cartels are inherently unstable because the history of cartels is the history of double-crossing. The best place in a cartel is to be on the outside undercutting it slightly to sell as you can at inflated cartel price.

The complication with cartels is competitors must sometimes coordinate their activities with their rivals in various ways such as agreeing product standards, undertaking joint ventures or licensing technologies to them.

Criminalisation of cartels may deter these business practices that promote consumer welfare. The process of innovation in new industries in particular often involves successful firms taking over the unsuccessful firms.

Serial competition is common in rapidly innovating industries with one dominant firm making hay for a while then quickly swept away. Merger law enforcement agencies do not handle the wake of creative destruction well.

There is no more cutthroat market than Hollywood. Yet the movie industry is riddled with collusion and joint ventures. Actors and producers can be collaborating on one film and  also be making another film that will be its rival in the box office when released.

The movie industry would not work without this incestuous mix of competition and collaboration. Joint ventures are aplenty between otherwise direct competitors in the film industry. When do these joint ventures become cartels threatened with criminal penalties?

What should be another working rule in competition law enforcement is when there is reasons to stay your hand, that is usually a good idea even if you do not have the reasons worked out yet. When in doubt, stay your hand.

It goes back to that extremely famous 1984 essay by Frank Easterbrook on the limits of anti-trust law. The essay was about errors in competition policy and law enforcement:

• When a competition law enforcer makes a mistake and closes off an efficiency enhancing practice or stops a pro-consumer merger, there are few mechanisms to correct this mistake; and
• If a competition law enforcer inadvertently does not stop a anti-competitive merger or lets a collusive or inefficient practice get through, at least there is market processes that will slowly chip away at his mistake.

Easterbrook argued that courts and enforcers should craft liability and procedural rules to minimise the sum of competition law’s error and decision costs:

The legal system should be designed to minimize the total costs of (1) anticompetitive practices that escape condemnation; (2) competitive practices that are condemned or deterred; and (3) the system itself

Competition law enforcers and policymakers made plenty of errors in the past. Chastened by their follies aplenty in the past, competition law policymakers should not approach any issue with overconfidence. They have had a dismal track record in aligning competition law with applied price theory and the basics of the economics of industrial organisation.

That is at best only a good start for the competition law enforcement agencies. This is because the economics of industrial organisation spent a lot of time condemning practices that neither restricted output or increased prices.

It took many decades for consumer welfare to be the exclusive goal of competition. Time and again protecting competitors from competition was the priority of competition law enforcement agencies.

The ICT revolution coincided with a revolution in competition law economics and policy. That revolution consisted of basing competition law on applied price theory and not condemning every novel or as yet unexplained practice.

In the high-tech industries, competition law runs a high risk of chilling innovation. As Joshua Wright said:

Innovation is critical to economic growth. Incentives to innovate are at the heart of the antitrust enterprise in dynamically competitive industries, and, thus, getting antitrust policy right in high-tech markets is an increasingly important component of regulatory policy in the modern economy. While antitrust enforcement activity in high-tech markets in the United States and the rest of the world is ever-increasing, there remain significant disputes as to how to assess intervention in dynamically competitive markets.

The relentless pursuit of Microsoft by the US Department of Justice at the behest of its competitors such as Netscape is notorious example of the chilling of innovation.

You are showing your age if you even remember who Netscape was. Its complaint was that Microsoft by giving away its browser was engaging in predatory competition.

Netscape want to protect consumers from the scourge of lower prices – from not having to pay $49 for the Netscape browser. You are showing your age if you have ever paid to install a browser.

Netscape had the advantage of a senior US senator representing the state where it was based. He happened to sit on the committee overseeing  the budget of the US Anti-trust enforcement agencies.

We are still waiting for the day when Microsoft finishes giving away its browser, excludes competition from the market for browsers, jacks up its price to make up for a good 20 years of giving away its browser and is not immediately threatened by new entry.

The intrepid competition law enforcers of the 1990s did not anticipate a business model where competitors profitably give their product away.

Thankfully, Facebook did not face competitors who charged for their social media. If  Facebook had faced such competition, what would the US Department of Justice thought of this anti-competitive practice of giving social media away. The scourge of lower prices again. That great bugbear of competition law enforcement agencies.

Facebook is doing the exact same thing that Microsoft did when it gave away the Internet Explorer browser. To this day, competition law enforcement agencies including the New Zealand Commerce Commission do not accept lower prices to be lawful in all cases without exception.

A test of how imbibed you are with the fatal conceit about competition law is to cast your mind back as to what your attitude was to the Department of Justice anti-trust lawsuit against Microsoft.

If you thought the anti-trust lawsuit against Microsoft was well-founded, you are an optimist about the efficient scope of competition law. To quote McKenzie and Shughart:

Microsoft’s critics come far closer to the mark when they complain that Microsoft has been “brutally competitive” than when they claim Microsoft is a “monopoly.” From our perspective, it appears that once again the Justice Department is using the antitrust laws to thwart competition by a highly successful American firm. To protect unsuccessful competitors, it is squelching competition.

A long time has passed since that suit. People can reflect upon the extent to which Microsoft have successfully monopolised browsing the Internet. It hasn’t. As Gary Becker said:

Anti trust policy should recognize that dynamic competition is often a powerful force when static competition is weak. The big policy question then is whether it is worthwhile to bring expensive and time consuming anti trust cases against still innovating firms that have considerable profits and monopoly power, given the significant probability that new competitors will before long greatly erode this power through different products? I believe the answer to that is no, and that policy should often rely on dynamic competition, even when that allows dominant firms only temporarily to enjoy economic power.

The law and economics of competition has been a bit of a glass house for the last 50 years. People should be careful about criticising new idea and attempts to be more modest about the positive contribution the competition law makes to society.

Competition law can subvert competition by stymieing the introduction of new goods and the temporary monopoly often necessary to recoup their invention costs and induce innovation. Sam Peltzman, when reflecting on the contributions of Aaron Director to the law and economics of competition said:

There are the myriad of ways in which real world business practices behave differently from the caricaturing in textbooks. Those differences sometimes arouses suspicious responses from economists. Visions of market power and deadweight loss triangles dance their heads, and some of the suspect practices have been constrained by anti-trust policy. Director rejected this kind of intellectual laziness, and he sought, sometimes successfully, to inoculate those around him against it.

Director approached all business practices with the methodology that entailed asking very basic questions and answering them in a rigorous logic that it appealed ultimately to facts. The style was verbal – some combination of Socratic dialogue and Adam Smith. This style had the disadvantage of producing few closed-form solutions. But it had the advantage of permitting analysis of the kind of problems that eluded simple solutions.

Indeed I believe that one reason for Director’s lasting influence he was able to show that simple judgements about business practices often cannot withstand rigorous scrutiny.

Economic theory and empirical evidence are full of examples of business conduct that reduce choice but increase consumer welfare through lower prices, more innovation, or higher quality products and services. Manne and Wright noted in the paper, Innovation and the Limits of Antitrust that:

Both product and business innovations involve novel practices, and such practices generally result in monopoly explanations from the economics profession followed by hostility from the courts (though sometimes in reverse order) and then a subsequent, more nuanced economic understanding of the business practice usually recognizing its pro-competitive virtues.

Competition law enforcement agencies are suing Google because it is anti-competitive. The dead hands of the competitors to Google are buried somewhere in those suits. Is there no learning. There is certainly no modesty about past mistakes about the proper scope of competition law.
