Just because something has value doesn't mean it has a price


If every last shred of incidental online value is given a price tag, we'll never harvest the full fruits of our ingenuity

When future economists look back on the dawn of the internet era, they will marvel that an age of such technological marvel was attended by a widespread, infantile mania for preventing positive externalities.

"Externalities" are the economist's catchall term for the spillover effects experienced by the people who are affected by others' activities. Most of the 20th century was spent locked in battle with the corporate vice of externalising negative costs. Companies are beholden to their shareholders, and so they are meant to save every penny they can, even when saving that penny might cost the rest of society several pounds. The classic example is toxic waste: processing industrial waste before it leaves the factory is a costly proposition, and so, whenever it is possible to do so, companies have defaulted to dumping their waste into the wider world. This is a much cheaper option — for the company.

For the world, it's vastly more costly. After all, when the offensive sludge is all neatly gathered at the effluent pipe's head-end, it is concentrated and handy, and can be gathered and fed into whatever decontamination or sequestration system is appropriate.

But once the sludge has exited the pipe and is out in the world, it has to be gathered up before it can be dealt with. Contaminated coolant can be sealed in barrels at the factory and sent for secure burial. Once it's dumped in a stream, you have to figure out how to get it out of the stream before you can clean it up – this is notoriously difficult.

What's more, streams feed into rivers, and rivers into oceans, and people drink from them and swim in them and eat the animals that swim in them and rely on them. What started as a waste-containment problem has become a public health emergency and an environmental catastrophe – the company's savings are the world's loss.

So policy wonks have spent a century thinking about creating the carrots and sticks necessary to minimise this externalising behaviour. The idea is to work out a system of fines and punishments that make it economically irrational to dump sludge, because the savings from doing so are offset by the penalties for getting caught. Getting this number right is notoriously hard, because you have to factor in some kind of multiplier of the penalty that accounts for the discount that rational – albeit psychopathically immoral – companies will apply based on the likelihood that they will not get caught.

Virtuous circles

But what about positive externalities? Historically, these have been a lot less contentious, and it's easy to see why. A positive externality arises when you do something you want to do that also makes life better for someone else. For example, if you drive your car slowly and carefully to avoid a wreck, a positive externality is that other users of the road have a safer time of it, too. If you keep up your front garden because it pleases you, your neighbours get the positive externality of slightly buoyed-up property values from living on a nicely kept street.

Positive externalities — virtuous cycles — are all around us. Your kid learns to speak because of all the people around her who carry on conversations and because of the TV shows and radio programmes where speaking occurs (as do immigrants like my grandmother, whose English fluency owes much to daytime TV after she came to Canada from Russia).

My flat – on the top floor, above a commercial building – gets some of the rising heat from the building below, capturing our downstairs neighbour's exhaust heat (on the other hand, we provide a positive externality to them by insulating their roof with our home).

The net is the natural home of positive externalities. Start with the "network effect" – the way that adding people to the network creates more value for existing users of the network (one fax machine is useless, two fax machines are slightly useful, a billion fax machines are indispensable, at least, until the web makes them obsolete). Every website that came along increased the likelihood that new users would find some reason to join the internet. Every new user that came along increased the likelihood that someone would make a website that tried to reach that user.

This is a kind of anti-entropic magic trick, using the exhaust from one process to create fuel for the next one. The most famous example is Google's PageRank algorithm, which began when the company's founders realised that every time a web creator added a link from one site to another, there was a kind of implied vote for the linked-to site – when I link to you, I'm implicitly saying that you have something I think others should see. This citation analysis (a common practice in academia, where journals who are widely cited are considered more valuable than less-cited journals; and where journal-articles that are more widely cited are considered more valuable as well) was wildly successful, and it showed that there was, latent on the web, an invisible mesh of authority that could be made visible with the right kind of analysis.

Google is a case-study in harvesting positive externalities. It offered a free, voice-based directory assistance number, and used the interactions users had with its software to build a corpus of common phrases, expressed in multiple accents and under a wide range of field conditions. Then it used this to train the voice-recognition software that powers its Android-based phone-search. Likewise, it mined all the publicly available translations on the web – EU documents that appeared in multiple languages, fan-based translations for subtitles on cult cartoons, and everything else it could find – and used this to train its automated translation engine, providing it with the context that it needed to figure out the nuance and sense of ambiguous phrases.

There are other companies that do well by harvesting these positive externalities. Facebook provides its users with a handy platform for socialising, and then – notoriously – mines their social graph to figure out how to sell things to them.

However, there's a wide difference between the two companies: much of Google's business revolves around capturing externalities from things you were going to make anyway. In many cases, the resources Google mines are public and remain in place even after Google's finished with them (for example, anyone can index the web and do the same citation analysis as Google).

Both Facebook and Google also try to entice the world into activities that generate externalities. Facebook is a giant behaviourist experiment designed to tempt you into systematically undervaluing your privacy, and it uses game-like mechanics to extract more personal data and more social-graph enumeration from its users. Google's a little less obvious about its enticements, but clearly, offering services such as YouTube and Blogger are mostly about figuring out how to earn money from the exhaust-stream from individual and corporate creativity. Facebook, and to a lesser extent, Google, try to claim ownership over your externalities by locking them up in proprietary walled gardens.

Taking a cut

But back to our era's defining mania: resentment over positive externalities. Many people and companies have concluded that if someone, somewhere, is getting value from their labour, that they should get a cut of that value. Irish newspapers are paying solicitors to demand money from websites that link to them, on the grounds that a website is improved if it contains a reference to the news, and that improvement needs to be paid for. Many people have accused Google of "ripping off" the public by indexing content, or analysing it, or both. Jaron Lanier recently accused Google of misappropriating translators' labour by using online translated documents as a training set for its machine-translation engine – an extreme version of many labour-oriented critiques of online business.

And take DRM – digital rights management – which is used to restrict the way you use the media you buy, such as ebooks, videos, and games.

DRM systems have been deployed to stop people from selling used games, to stop them lending their ebooks, to stop them from taking DVDs from one country to another. This is pure positive-externality resentment.

The reasoning for DRM goes like this: "I sold you this [ebook/game/video] for the following uses. If you figure out a way to get any more value out of it, it belongs to me, and you can't have it, until and unless I decide to sell it to you."

In the pre-digital world, this would have been laughable. "I sold you that book: if you want to use it to keep the table from wobbling, you'll have to pay me extra." Or: "I sold you that game to play in your house. How dare you bring it on holiday with you?! You owe me!" Or: "That TV was sold to you for the purposes of watching programmes, not to be used as a white-noise machine to lull your newborn to sleep, and certainly not to support a pile of knick-knacks!"

Of course, removing positive externalities also removes value. Cars are worth more because of the used-car market. University textbooks command a higher price because of the market for used textbooks. If either sector managed to kill those externalities, it would be selling goods that its customers valued less (and would likely find that they demanded lower prices for them, too).

I was at a TV DRM meeting once where a representative from the US-led Motion Picture Association proposed that broadcasters should be able to selectively block the use of wireless retransmitters – the sort of thing that lets you have a receiver in the sitting-room that fed a TV set in your bedroom – because "watching TV in a room other than the one the show is being received in has value, and if it has value, we need to be able to charge money for it".

That's the crux of this irrational fear of positive externalities: "If something I do has value, I deserve a cut." It's one thing to say that someone who hires you to do a job, or purchases your product, should pay you money. But positive externalities are the waste-product of something we were already going to do. They're things that you have thrown away, that you have thrown off, that you have generated in the process of enjoying yourself and living your life.

The mania to internalise your positive externalities is the essence of cutting off your nose to spite your face. I walk down the street whistling a jaunty tune because I'm in a good mood — but stop as soon as I see someone smiling and enjoying the music. I keep my porchlight on to read by on a warm night, but if I catch you using the light to read your map, I switch it off, because those are my photons — I paid for 'em!

Worse still: the infectious idea of internalising externalities turns its victims into grasping, would-be rentiers. You translate a document because you need it in two languages. I come along and use those translations to teach a computer something about context. You tell me I owe you a slice of all the revenue my software generates. That's just crazy. It's like saying that someone who figures out how to recycle the rubbish you set out at the kerb should give you a piece of their earnings. Harvesting positive externalities involves collecting billions of minute shreds of residual value – snippets of discarded string –and balling them up into something big and useful.

If every shred needs to be accounted for and paid for, then the harvest won't happen. Paying for every link you make, or every link you count, or every document you analyse is a losing game. Forget payment: the process of figuring out who to pay and how much is owed would totally swamp the expected return from whatever it is you're planning on making out of all those unloved scraps.

In other words, if all latent value from our activity has a price-tag attached to it, it won't get us all paid – instead, it will just stop other people from making cool, useful, interesting and valuable things out of our waste-product.

What's so wrong with negative fields anyway?



When England set cautious fields they are called tactically naïve; but they win
Ed Smith
July 4, 2012


A month ago, I had one of the most interesting conversations I've ever had about sport. It was in a tiny restaurant in Paris with the brilliant football writer Simon Kuper. The subject was how Spain became the world's dominant football culture.
Spain have now won Euro 2008, the 2010 World Cup and Euro 2012. They are also currently world champions at Under-19 and U-17 levels. The Spanish way - high skill, brilliant passing, and little focus on physical size or brutality - has mastered the world. Not only are Spain serial winners, they have also set football's philosophical agenda.
Our conversation in Paris began with football, but I realised afterwards that the question applied to all sports. How do games evolve? Can original thinkers change their sports forever? Is intelligence - or better still, insight - the most underused resource in sport? Can you think your way to success?
Kuper explained to me that the origins of modern football began with a single inspired insight by the superb Dutch player and coach Johan Cruyff. Like many great ideas it sounds obvious but it is actually profound. The pass, that is what really matters in football. The precision, the perfection of the pass. Everything else - the arm-waving, the brave running around, the passionate sweat and tears - is peripheral. Being better at passing is what wins football matches.
Prompted by Cruyff, Barcelona set up La Masia academy to educate players about the pass. When you watch Spain mesmerise opponents, you are watching an idea brought to life. There is a bloodline that runs from Cruyff - via Pep Guardiola - to Xavi, Iniesta and Fàbregas, the champions of Europe, champions of the world. One idea changed the game forever. Spanish dominance is not just based on skill. It is founded on brains.
Yet the most interesting part of the story is the resistance to Spain's success, the refusal to follow the logic that has created it. Throughout Euro 2012, English pundits continued to accuse Spain of being "boring". The English old guard even condemned Spain's selection and tactics. How risk-averse, how stupid of Spain not to play a centre forward at all? Well, Spain won the final 4-0, without playing a centre forward for much of the game. Their first goal was brilliantly set up by Fàbregas, a midfielder picked instead of a regular centre forward. Stupid Spain, boring Spain? Behind the insult, observe the anger. When a pack of conventional thinkers are confused, they lash out at what they don't understand.
We see the same criticisms thrown around in cricket, the same reluctance to accept that new thinking might lead to better results. Here is an example. Pundits often ridicule captains for setting "negative" fields. The assumption is that it is always a "positive" move (i.e. that it will lead to more wickets) to have more slips and fewer fielders saving the single.
But what is positive, what is negative?
When I was a player, I often liked batting against very "positive" fields. Because I liked to bat at a reasonable tempo, feeling that the scoreboard was ticking along. Many players have a natural tempo, a pace of scoring that makes them feel they are in control. In a perfect world, of course, batsmen should be able to defend for hours without worrying about the scoring rate. But most batsmen are human beings.
 
 
I would much rather bat against an egotistical captain trying to impress the crowd than an unobtrusive captain trying to stop me batting in the way that suited me
 
That's why I often found it easier to score runs against flashy, "positive" captains, who were always trying to set eye-catching "aggressive" fields. While they were arranging catchers in apparently original groupings, runs flowed from the bat. I would much rather bat against an egotistical captain trying to impress the crowd than an unobtrusive captain trying to stop me batting in the way that suited me.
Now I've retired, I can reveal an effective and underused tactic: stop people scoring (whatever the type of match) and you'll probably get them out. This has become even more relevant to Test cricket during the era of T20 cricket. Batsmen have become increasingly used to hitting boundaries in Test cricket because T20 has changed the way people feel about their natural scoring rate. That's why Andrew Strauss is unafraid to have more fielders saving one and fewer catchers in Test cricket.
When England set cautious fields, they too are called "tactically naïve". And they win. When Spain don't play a centre forward, they are called boring and tactically naïve. And they win.
It is time to revisit some definitions. What are tactics but tools for winning sports matches? And since when was it naïve to play to your strengths?
A case study of thinking and winning is the story of the Oakland Athletics in baseball. Thanks to the book, and now film, Moneyball, it is has become one of the famous stories in sport. As with Cruyff's insight about the pass, the over-performance of the Oakland A's began with a single insight. The best way to approach winning a baseball match is not thinking about scoring runs. It is to focus on getting on base. A run is usually the by-product of getting on base. Runs are hard to predict; getting on base is much easier to assess and calculate. So the Athletics focused on the tractable, controllable parts of the match, ignoring the headline-grabbing end-product.
In 2002 the Athletics unveiled their new strategy. Guess what: the pack of baseball pundits and insiders didn't like it. They accused the Athletics of wrong-headedness, hubris and over-intellectualism. Undeterred, Oakland won a record 103 matches out of 162.
Conventional wisdom moves at a glacial pace because people become attached to ideas that are no longer relevant. Military historians say that generals are always preparing to fight the war that has just ended. So it is in sport.
Boring Spain, naïve England, wrong-headed Oakland? I prefer the idea that sport is always evolving, with new ideas driving the pace of change.

Aggressive Captaincy

Captains: follow Clarke's lead

In the long run, captains who aim to win and set fields that will get them wickets are the ones who will succeed and last
April 22, 2012


Michael Clarke is quickly establishing a well-deserved reputation for brave and aggressive captaincy. His entertaining approach is based on one premise: trying to win the match from the opening delivery. This should be the aim of all international captains, but sadly it isn't.
In every era there are Test captains who prefer to attain a position of safety before they go all out for victory. These captains are frightened stiff of the Michael Clarkes, who make it obvious they are not interested in a draw. At least 50% of international captains consider a draw to be a good result and when that option is removed they easily panic.
The first thing a captain like Clarke understands is that he will lose some matches in constantly striving for victory. Once that premise is accepted the captain has reached the stage where he hates to lose but doesn't fear it. There's a huge difference: the latter is a positive state where the captain will do everything in his power to win; the former a mindset where the captain sets out not to lose.
An important indicator of a captain's thinking is his field placings. A positive captain will always make the opposing batsmen feel their very existence is threatened. Through his field placings he allows his bowlers to turn at the top of their mark and see where a wicket (other than bowled, lbw or through the batsman's stupidity) can be claimed. 

A bowler operating to a purely containing field is like Zorro without his sword; he's not very threatening. There has been plenty of discussion on whether the shorter forms of the game will adversely affect batting techniques and turn bowlers into cannon fodder. What the 50- and 20-over matches have actually had a marked influence on is field placings.

Whereas the No. 1 priority, by a wide margin, used to be taking wickets, followed by saving singles, and then, way off in the distance, stopping boundaries, in the mind of the modern captain the last one has assumed far too much importance.

The almost robotic use in Test matches of a deep cover point and a backward square leg on the boundary, regardless of whether the ball is being played in that direction, borders on mindless captaincy. When a fieldsman is unemployed for half an hour but the captain still retains him in that position, you have to wonder: who appointed this captain?

The change in attitude to field placings is perfectly summed up with some typical Caribbean humour and common sense.

Former West Indies fast bowler Herman Griffith was captaining a Barbados club side in the 1930s once, and called on his debutant offspinner to have a trundle. "Where do you want the field?" asked Griffith politely.

"I'd like a deep-backward square leg, a midwicket on the boundary and a long-on and long-off," replied the youngster.
"Give me the ball," growled Griffith.
Not unreasonably, the young man asked, "Why?"
"You intending to bowl shite," came the forthright answer.

Nowadays, most bowlers would be horrified if the captain didn't automatically give him a number of protective fielders in the deep. Clarke is not such a captain.

Sadly, his latest gambit - a challenging declaration at the Queen's Park Oval, which was answered with equal bravado by Darren Sammy, failed because of inclement weather. Nevertheless, it's to be hoped their positive endeavours have acted as a sharp reminder to the administrators.

In Test cricket the captain is allowed free rein. We've seen in the case of Clarke and Sammy what's possible when two captains use a bit of imagination and have a desire to produce a result. It's impossible to legislate for captaincy imagination. In the 50-over game, which is highly regulated through a variety of Powerplays, and bowling and field restrictions, there is less real captaincy involved.

Wherever possible, the captaincy should be left to the skippers, and those with imagination will prosper. Hopefully those who lack inspiration and the nerve to face a challenge will be quickly replaced by the selectors.

Viv Richards is 60

Sir Viv Richards: the personification of grace and menace combined

Happy 60th birthday, Sir Viv Richards – one of the finest postwar batsmen of them all who could reduce an attack to rubble
Sir Viv Richards

This I can see as clearly now as if it were only yesterday: pitch at Lord's, under covers for a week and more and as green as Paddy's Day, me with a new ball, and the start of a much-delayed, postponed and greatly reduced domestic limited-overs semi-final. The first delivery was spot-on, bang on length and line and, on pitching, it jagged back sharply off the seam and sank into the unprotected inside of the thigh of the batsman pushing forward.

The next was all but identical (the pitch marks, scarred on the grass, were within six inches of one another) and again the batsman came forward at it. Only this time he changed his mind midway, shifted his weight on to the back foot, and, clean as you like, thumped it with a vertical bat and high elbow not just over mid-off, or even the boundary rope, but over the corner of what is now the Compton stand and on to the Nursery. It remains the single most devastating shot I have ever seen. And Vivian Richards played a few in his time. What would he be worth today?

It is more than a year since last I saw him. Or rather he saw me, across an airport transit lounge, me en route to the Ashes, he for a tour of King and I shows with Rodney Hogg. "Hey Selve, what's happening, man?" He looked dapper, a porkpie hat perched rakishly in place of the familiar maroon cap, a little thicker round the face but still that Big Bad John "kinda broad at the shoulder and narrow at the hip" appearance that made him look as much like a top middleweight as the greatest batsman of the modern era. Even as he reaches three score years on Wednesday, he looks fighting fit.

So, from Singapore to Sydney, we supped a little and chewed the fat. There were things I wanted to ask him that I never had. Which of all the great West Indies fast bowlers of his time would he pick for his dream quartet? Andy Roberts, he said, his fellow Antiguan with an astounding cricket brain who was there at the start of it all; and the brilliant, much-lamented Malcolm Marshall. Then came Mikey, the great svelte Holding. And finally not the rumbling faithful Big Bird Joel Garner, but instead the brooding stringbean Curtly Ambrose. But, Richards admitted further, if he wanted someone to blast him a wicket, without fear, favour or consequence, there was none more chilling than Colin Croft.

Now tell me, I asked him, since it's a long time over, how do you think that bowlers – or specifically, me – should have approached the task of bowling to you. I had successes, but generally they would have been early on in an innings as he sought the upper hand and took calculated risks. Hard graft after that. You had to be aggressive, he said with some passion, aggressive. It mattered not if fast, slow or medium, spin, swing or seam, you had to demonstrate positive intent or you were shot from the start.

When, after he took guard, he wandered down the pitch, tilted his head back and, looking down his aquiline nose to eyeball the bowler, it was almost as if he was sniffing the air through his flared nostrils for the scent of fear. He wanted to feel the ball "sweet" off the bat from the off, and then he knew it was his day. Yeah aggressive, he repeated, he respected that.

But this was always easier said than done because of the way he set it up. There is an analogy with the buzz in a theatre before the curtain goes up on a great thespian. The wicket falls, but he allowed things to settle, waiting for the arena to clear, the celebrations (more muted in those days) to die down. The theatre lights dimmed and expectation became electricity. Everyone knew who was coming. And when he finally made his entrance, swaggering down the steps, cudding his gum, and windmilling his bat gently, first one arm then the other, it was a personification of grace and menace combined, the walk as unmistakable as had been that of Garry Sobers, to my mind his only rival as the finest postwar batsman of them all.

I put on a performance, he told me, it was part of my act. He wanted to dominate and the genesis of that process happened even before he closed the dressing-room door behind him. His reputation preceded him like an advance guard. It continued with the languid wicketwards saunter, the slow precision with which he took guard, the way he ambled down the pitch to tap down an imaginary mark, all the while looking for, and not always finding, eye contact with his adversary. Then he would smack the end of his bat handle with the palm of his right hand, a final intimidatory gesture.
There have been giants of the game contemporary and since, batsmen of vast pedigree and achievement: Greg Chappell, Lara, Tendulkar, Ponting, Dravid, Kallis, Sangakkara, Hayden and others. Each on his day could reduce an attack to rubble. But Richards had an aura given to no other. Truly he was scary. Happy birthday, Viv.
