iPhones and ringtones: a parable of markets.

"Markets in everything!"

There is a problem in the New Statesman office. Like so many companies, we have a growing abundance of iPhones. At least half of the 40 million they've sold are here somewhere, by my count. But all these people having the same phone leads to a downside: the distinctive Apple message alert goes off, and everyone checks their screens thinking that they are the ones with a new text.

There is an easy, socially optimal solution to this problem, of course: everyone changes their text tone to something new, we all grow to recognise our individual tones, and confusion need never reign again.

Unfortunately, what is socially optimal is not individually optimal. I don't want to change my ring tone, because I've already learnt to respond to it. If everyone else changed theirs, then I could keep mine the same. But those incentives are the same for everyone else; no-one wants to be the first mover, and everyone hopes to be a free-rider.

Why? Well, an economist might say its because there are no markets in action. If everyone could bid to be the person who gets to keep their old ringtone, then people would have an incentive – in the form of cold, hard cash – to switch, while the person who most wants to keep their phone sounding the way it used to forks out the money equivalent to how much they care. If we truly have an efficient market, then this cannot fail to make everyone better off. And if the highest someone is prepared to pay is lower than the lowest it would take to make everyone switch, then we are already at the optimal solution.

The alternative to markets, of course, is government intervention. We don't have a government, but we do have an editor, who could very easily impose a rule mandating that employees use custom ringtones. That would work almost as well, although it wouldn't be the optimal solution. And with that, there's always the risk of corruption. What happens when our he gets an iPhone?

Zac Goldsmith to quit as Tory MP after Heathrow decision announced

The environmentalist is expected to stand as an independent candidate.

Zac Goldsmith, the MP for Richmond Park and North Kingston, and a committed environmentalist, has announced his resignation after the government backed a third runway at Heathrow. 

He has told his local Conservative association of the decision, according to The Huffington Post. The group has reportedly agreed to back him as an independent in a by-election.

Goldsmith tweeted: "Following the Government's catastrophic Heathrow announcement, I will be meeting my constituents later today before making a statement."

Goldsmith had previously pledged to resign if the government went ahead with the decision. By quitting, he will trigger a by-election, in which he is expected to stand as an independent candidate. 

Speaking in the Commons, he said the project was "doomed" and would be a "millstone" around the government's neck. He said: "The complexities, the cost, the legal complications mean this project is almost certainly not going to be delivered."


However, there is no guarantee it is a by-election he will win. Here's Stephen Bush on why a Richmond Park and Kingston by-election could be good news for the Lib Dems.

After years of speculation, the government announced on Tuesday it was plumping for Heathrow instead of Gatwick. Transport secretary Chris Grayling called it a "momentous" decision.

The announcement will please business groups, but anger environmentalists, and MPs representing west London constituencies already affected by the noise pollution. 

In a recent post on his constituency website, Goldsmith highlighted the noise levels, the risk of flying so many planes over densely-populated areas, and the political fallout. He declared: "I promised voters I would step down and hold a by-election if Heathrow gets the go-ahead and I will stand by that pledge."

Once a Tory "nice boy" pin up, Goldsmith's reputation has suffered in the past year due to his campaigning tactics when he ran against Sadiq Khan for London mayor. Advised by strategist Lynton Crosby, Goldsmith tried to play on racial divisions and accused Khan of links to extremists. Despite enjoying support from London's Evening Standard, he lost.

The former mayor of London, Boris Johnson, once declared he would lie down "in front of those bulldozers" but has toned down his objections since becoming foreign secretary.

Green MP Caroline Lucas urged him to follow Goldsmith and resign, so he could team up with her in opposing the extension at Heathrow.

Labour, in contrast, has welcomed the decision. The shadow Transport secretary Andy McDonald said: “We welcome any decision that will finally give certainty on airport expansion, much needed in terms of investment and growth in our country." He urged the government to provide more detail on the proposals.

But London's Labour mayor Sadiq Khan accused the government of "running roughshod" over Londoners' views. He said: "Heathrow expansion is the wrong decision for London, and the wrong decision for the whole of Britain."
