Sellers on Amazon use automatic tools which pushed a book on flies up to $23,698,655.93

Robo-pricing gone wrong

Barney Jopson for the Financial Times:

Amazon sellers – using third-party software – can set rules to ensure their prices are always, for example, $1 lower than their rivals’. More complex algorithms can analyse data to set prices most likely to secure a prominent position on the site.

Last year, out-of-control algorithms inflated the price of The Making of a Fly, a genetics book, to more than $23m, according to Michael Eisen, a biologist who blogged about it.

Eisen's blog is a great case study. My favourite excerpt:

The behavior of [one of the sellers,] profnath is easy to deconstruct. They presumably have a new copy of the book, and want to make sure theirs is the lowest priced – but only by a tiny bit ($9.98 compared to $10.00). Why though would  [the second seller] bordeebook want to make sure theirs is always more expensive? Since the prices of all the sellers are posted, this would seem to guarantee they would get no sales. But maybe this isn’t right – they have a huge volume of positive feedback – far more than most others. And some buyers might choose to pay a few extra dollars for the level of confidence in the transaction this might impart. Nonetheless this seems like a fairly risky thing to rely on – most people probably don’t behave that way – and meanwhile you’ve got a book sitting on the shelf collecting dust. Unless, of course, you don’t actually have the book….

My preferred explanation for bordeebook’s pricing is that they do not actually possess the book. Rather, they noticed that someone else listed a copy for sale, and so they put it up as well – relying on their better feedback record to attract buyers. But, of course, if someone actually orders the book, they have to get it – so they have to set their price significantly higher – say 1.27059 times higher – than the price they’d have to pay to get the book elsewhere.

Of course, realistically this sort of thing isn't the natural result of computers entering the fray; if the two booksellers had used the tool at all well, they would presumeably have entered some sort of upper bound, where an actual human person would be notified.

Really, this is just another example of how the internet makes economics textbooks come to life. This is exactly the sort of situation which sounds like it might happen in theory, but never could in practice, and then, all of a sudden, it does. Amazon has already been known to practice dynamic pricing, charging customers the most it thinks they will pay. What next?

A really expensive book? Or a really well-designed fly?

Hull revisited: What happens when a Brexit stronghold becomes City of Culture?

We report from Hull, to find out if you can replace the kind of nostalgia that led to a Leave vote with cultural investment.

At 75 metres long, the offshore wind turbine blade erected across Queen Victoria Square, in the heart of Hull, is a sculpture intended to mark a new chapter in the city’s history. For the next 12 months, Hull, a city of more than a quarter of a million people in the northeast of England, will be the UK’s City of Culture.

The 28-tonne blade hails from the local Siemens plant. The German technology company employs around 1,000 people in the area, making it Hull’s biggest single employer.

Seen up close in this context – laid dormant in the middle of a town square instead of spinning up in the air generating energy – the structure is meant to remind passersby of a giant sea creature. It is also, I’m told, an allusion to Hull’s rich maritime history.

Nostalgia is a big thing in this part of the country. At one point, Hull was the UK’s third largest port but technology and privatisation drastically changed that. The battle over cod fishing with Iceland in the waters of the North Sea 40 years ago has also dealt a major blow to a region with a long and proud trawling tradition.

People here still talk about a bygone era when the fishing industry provided jobs for everyone and there was enough money to go around.

Fast forward to 2017, and the country’s new capital of culture is the same city that voted 67 per cent in favour of leaving the EU last June. Its new-found prestige, it seems, is not enough to erase years of neglect by a political class “too busy for commoners like us”, as one resident puts it.

“More than a message to Brussels, it [the Brexit vote] was a message to Westminster,” Paul Leeson-Taylor, a filmmaker born and bred in Hull, tells me. “For the first time in a long time people in Hull felt like they had the chance to change something, and they took it.”

But while speaking to people on the high street and hanging out with locals at the Community Boxing Club in Orchard Park, one of the city’s most deprived areas, there is one word that consistently popped up in conversation – more than any specific policy from Westminster or the much-hated rules “dictated” by Brussels. Foreigners.

According to official figures, Hull’s population is 89.1 per cent white British. Still, immigration is big on people’s minds here.

During my two-day stay in the city, I find myself being the only black person in most places I visit – I’m certainly the only black guy at the boxing club. So when someone begins a sentence with “I’m not racist but…”, I know a tirade on immigrants is about to ensue.

“There are just too many of them,” Nick Beach, an estate agent whose Polish clientele is a big part of his business, tells me as he is about to teach a boxing class to local children. Beach was born in Shepherd’s Bush, in West London, but has been living in Hull for the last 20 years.

“When I go down there these days and go into Westfield shopping centre, it is very rare you get an English person serving you now,” he says. “I just find it disappointing that you go into your capital city and you are a minority there.”

These are the much-discussed “left behind”, a white working-class community that has gained particular prominence in a time of Brexit and Donald Trump. Under economic pressure and facing social change, they want to have their say in running a country they claim to no longer recognise.

For Professor Simon Lee, a senior politics lecturer at the University of Hull, immigration is only a superficial layer when it comes to explaining the resentment I witness here. For him, the loss of the empire 70 years ago is still something that as a country Britain hasn’t come to terms with.

“The reason for us to be together as a United Kingdom has gone, so what is the project?”

As destiny would have it, a foreign company will now play a major role on Hull’s economic future, at least in the short term. In the wake of the Brexit vote, there were widespread fears Siemens would pull out of the region and take its factory elsewhere. With the massive blade looming large in the background, Jason Speedy, director of the blade factory in Hull, assures me that isn’t the case.

“The Brexit decision has made no difference. We have made our investment decision, so Siemens, together with the Association of British Ports, has put in £310m. It’s all full steam ahead.”

As Hull becomes the country’s cultural hub for the next few months, the hope is that its residents stop looking back and start looking forward.

For Professor Lee, though, until there is a complete change in the power structures that run the country, the north-south divide will remain – with or without the EU. “The way you kill nostalgia is to have something new,” he said. “The reason why people here are nostalgic is because there is nothing to replace it with.”
