Tenuous economic lessons drawn from detergent shoplifting

The Tide is turning.

Last year, I wrote about the extraordinary news that Tide – a popular brand of laundry detergent – was being stolen and used as a black-market currency across the United States (I also titled the post Laundered Money which I am still proud of ten months later). The retail price is high, the resale value is only slightly lower, it's impossible to track and everyone uses it. I looked at how well it would work as a unit of exchange:

Crucially, one bottle of it is identical to any other, a quality economists call "fungibility", putting it in the same class as oil, precious metals, or currency itself. If someone lends me a bottle of Tide, I don't have to return the same one to them when my debt is called in – in fact, because there are no serial numbers, it would be impossible for them to tell even if I did…

[Stolen] Tide is also a highly liquid commodity, frequently traded, which will allow a natural, and relatively stable, value to emerge for it.

Now, New York Magazine's Ben Paynter has done further investigation on the Tide-boosting phenomenon, and taken some of the magic out of it. It turns out that while a lot of people are stealing a lot of detergent, there's less evidence of the currency side of it. Crucially, Paynter, who was speaking to police in Maryland, didn't hear the same stories that Kentucky police passed on in March 2012 of people exchanging Tide for drugs, or being offered Tide instead of drugs. Instead, it's just your common-or-garden people-are-shoplifting-something-to-sell-it-and-use-the-money story.

But! There's still tenuous economic lessons to be drawn from the NY Mag piece. The first comes when the Maryland police describe their frustration with the fact that the penalties for a misdemeanour aren't that high:

After [Sergeant Aubrey Thompson's] team busted one area shop owner for taking in stolen Tide, the perpetrator struck a deal for a $250 fine and a form of probation—then turned around and raised the price his store charged for Tide by $3.

What we're seeing here is an example of someone with price-setting power passing on a regulatory cost. Simple models normally wouldn't ascribe price-setting power to the owner of a lowly neighbourhood grocery store, since it's more typically found in examples of monopolistic competition. But in reality, every shop owner has a quasi-monopoly over "shops in this location", which grants them the ability to set prices a bit. (That is: even if you know your corner-shop is charging you 10p more than the supermarket down the road, you still pay up, because you don't want to walk).

That price-setting ability lets the shop pass on costs incurred from regulation – in this case, the regulation which ensures that it cannot resell stolen goods. The owner treats a $250 fine as just another cost of doing business, and raises the price of Tide accordingly.

And yes, laws against reselling stolen goods are regulation. Think of that next time you hear someone railing against "red tape".

The other tenuous economic link comes from Paynter's description of the history of Tide:

When the company released Tide in 1946, it was greeted as revolutionary… Procter & Gamble, naturally, patented its formula, forcing competitors to develop their own surfactants. It took years for other companies to come up with effective alternatives.

It's a good description of the plus-side of patents. Procter & Gamble gets a reward for its innovation by being guaranteed-first-to-market, while competitors, eager to chase that market, develop other surfactants alongside. The pace of human invention speeds up, and after less than thirty years, all that knowledge is released into the public domain for anyone to apply.

It also reminds us what's broken with much of the current intellectual property regime. Imagine if, instead of patenting a surfactant, P&G had patented "a method for cleaning clothes" which described nothing more than "the application of a surfactant to fabric in water". Any other surfactants invented by competitors would then still be covered by the P&G patent, giving the company a monopoly over that entire method of cleaning clothes. Worse still, what if P&G had applied for that patent before anyone had actually invented a surfactant? The company could then sit back, wait for someone else to actually innovate, and then sue them for infringement when they do.

That rather describes the state of patents now, at least in the IT industry. Consider the patent trolls who are asking for $1000 from end-users who have networked scanners:

He said, if you hook up a scanner and e-mail a PDF document—we have a patent that covers that as a process.

The same legal framework which enhanced innovation in the 1940s may well be hindering it now. Worse, it has basically turned into a license for extortion.

But at least our clothes are clean.

Andy Burnham's full speech on attack: "Manchester is waking up to the most difficult of dawns"

"We are grieving today, but we are strong."

Following Monday night's terror attack on an Ariana Grande concert at the Manchester Arena, newly elected mayor of the city Andy Burnham, gave a speech outside Manchester Town Hall on Tuesday morning, the full text of which is below: 

After our darkest of nights, Manchester is today waking up to the most difficult of dawns. 

It’s hard to believe what has happened here in the last few hours and to put into words the shock, anger and hurt that we feel today.

These were children, young people and their families that those responsible chose to terrorise and kill.

This was an evil act. Our first thoughts are with the families of those killed and injured. And we will do whatever we can to support them.

We are grieving today, but we are strong. Today it will be business as usual as far as possible in our great city.

I want to thank the hundreds of police, fire and ambulance staff who worked throughout the night in the most difficult circumstances imaginable.

We have had messages of support from cities around the country and across the world, and we want to thank them for that.

But lastly I wanted to thank the people of Manchester. Even in the minute after the attack, they opened their doors to strangers and drove them away from danger.

They gave the best possible immediate response to those who seek to divide us and it will be that spirit of Manchester that will prevail and hold us together.
