Collaborative working groups are a necessity in many industries: if you want your luggage transferred from one airline to another, or exam results at one university credited to another, or a gizmo to work in a USB port, you're going to rely on the backroom folks who have got together and worked out the protocols that make it all happen. Consumers unambiguously benefit.
Industry associations can sometimes go over the (not always obvious) line between consumer-friendly collaboration and producer-friendly collusion. The latest in the gun may be technology working groups in the German car industry, which are alleged to have colluded on collectively introducing cheaper but less effective technology to control diesel engines' exhaust. The airlines went too far when they colluded on air cargo surcharges. And it was interesting to note that the Commerce Commission's latest Competition Matters conference had a session on 'The anti-competitive potential of industry groups', possibly signalling that they've become an issue of greater interest locally, too.
But as a reminder of the large amount of welfare-enhancing cooperation that well-meaning working groups can achieve, here's a question for you: where did the time zones in the US come from?
A lot of people tend to assume it must have been the guv'mint. But as this plaque on the corner of La Salle Street and Jackson Street in Chicago reminds us, it was actually entirely the work of the private sector. The US railroads got together on the site of the plaque on October 11 1883, agreed on four time zones each an hour apart, and implemented the whole thing five weeks later on November 18. As soon as they did, it became immediately obvious that this was a hugely sensible idea, and everyone else, including the federal and state governments, fell in behind.
Can you imagine a modern western government managing to do anything as effective as quickly as the railroads did? As it was, it took the US government more than 34 years to formally ratify what the railroads arranged in five weeks.
Welfare economists are fond of 'Pareto optimality', but real life examples tend to be hard to find. I'd like to propose the US time zone setting: there can't have been anyone much inconvenienced by dropping the old system, and uncountable numbers of people had their lives simplified.
