Property is – theft?

One of the fundamental assumptions in economics is the existence of clearly assigned property rights with legal recourse if these are breached. It is rarely written down in the lists of assumptions taught to students but it was a central part of the brilliance of Ronald Coase that he highlighted the important role of property. In fact, there are norms as well as rights, the things one takes for granted in making a purchase or sale about what’s included and excluded in the transaction. For instance, when you buy a meal in a restaurant, the assumption on both sides is that you’re buying the food but will not be entitled to take the plate and glass away with you. Some hotels clarify one area of ambiguity by posting notices announcing that if you like the bathrobe so much you can purchase one in reception to take home; but many of assume we’re allowed to take the little bottles of shampoo.

The transformation of so many physical items into digitised ones is making old assumptions about property rights contentious. One fascinating example is the case John Deere tractors have taken to US copyright courts claiming farmers can no longer fix their tractors but have to take them to an approved agent and pay the company – because the company has not transferred the digital rights to the software now operating hi-tech tractors.

The End Of Ownership: Personal Property in the Digital Economy by Aaron Perzanowski and Jason Schultz (both law professors) has lots of examples (including the John Deere one) of the shifting notion of ownership, and the terrain this opens up for contests. The book is in the spirit of Lawrence Lessig’s Free Culture and other authors who have worried about the massively expanded scope of DRM. Although less in campaigning mode, the authors of this book argue that personal property rights over digital items need far greater clarity, and should have due legal protection. If you own something, you should be able to transfer it, for example. They write:

“The label ‘property’ carries a great deal of rhetorical force. That’s why patent and copyright holders have adopted the language of property, and why they have seen such success in the courts and Congress in their efforts to strengthen, expand and extend those rights. But … what counts as property, the rules and exceptions, and the way we resolve conflicts between property owners, are things that cange over time.”

They are not against non-ownership, but argue the terms of this – rental in effect – must be clear and not buried in terms of use documents. No company should be able to repeat Amazo’s surprise move in 2009 of deleting copies of George Orwell’s 1984 that readers thought they had purchased to own. The authors make some specific suggestions – for instance, they suggest courts should stop seeing licensing agreements as contracts, and regulators should consider banning ‘buy now’ buttons for digital goods that the provider intends to retain ownership of. DRM should be reformed with an update of the DCMA (“a major policy misstep”). Above all, they argue for reform of copyright law, to restore the economic balance between ensuring there are adequate incentives to innovate and create and spreading as widely as possible the consumer benefits of innovation.

The End of Ownership also mentions in passing the latest manifestation of a temporary access world, the ‘sharing economy’. Digital platforms are making it a bit less necessary or desirable to won a car, or a holiday home. But these are physical assets so actually do not seem all that relevant to the main themes of the book.

It’s a bit lawyerly, and American (although US law in this area has had global effects). Nevertheless a very thought provoking read. Not that I see US lawmakers leaping to respond to its proposals just at present.

How diversity pays off

Scott Page’s new book The Diversity Bonus: How Great Teams Pay Off In The Knowledge Economy looked timely, arriving as it did on my desk just before the Google memo furore. It’s a continuation of his previous book The Difference, putting logical detail and empirical evidence on the claim that when problems are hard and multidimensional, they are better addressed by cognitively diverse groups of people. This is a generalisation in a way of Philip Tetlock’s work described in Superforecasting, as his super-forecasters were people applying a range of models to their forecasting problems. Predicting is one kind of problem; Page considers the whole gamut – problem solving, truth seeking, creating – of non-routine cognitive tasks.

He emphasises that he is making a pragmatic case, although this does not mean the normative case for diversity is unimportant. He also stresses that random diversity will not do the trick. The character of the problem shapes the types of diversity required. But without it, the outcome is the madness, not the wisdom, of crowds.

Page categorises people’ cognitive repertoires in terms of five tools: information (data, facts); knowledge (expertise in a domain); heuristics (rules of them, techniques); representations (perspectives on the situation); and mental models (simplified, systematic descriptions). The group’s repertoire will be the union of the individual members’ repertoires. Diversity is emphatically not like portfolio diversification. Spreading risks, diversification, gives an average outcome. Diversity gives the outer envelope of the team’s combined various abilities.

Putting these together helps think about the link between cognitive and identity diversity, and there is a link. Some problems are more multi-dimensional than others, and have aspects that speak to group identities. Some parts of the cognitive reperoire depend more closely on group identity because they will be determined in part by individual experience. Take representations: there is a lovely example of how different the range of possibilities will seem – given that we start from where we are – to someone trained in the grid of Cartesian geometry and someone trained with a polar perspective: square versus wedge-shaped ‘adjacent possibilities’. Combining the square and the pie slice gives a bigger space of possibility.

As for the Google memo issue, Page notes that where organisations and societies are now is only partially informative about the value of diversity. Repeated acts of discrimination will inhibit people’s interest in pursuing certain paths they would do well in, so there will have been ample prior self-selection that sheds no light at all on how much better challenges could be met with more diverse teams. “The evidence we have of diversity bonuses understates the potential contribution of diversity because the evidence comes from the world as it is, not the world as it could be. A more inclusive world would produce larger bonuses.”

And the evidence is pretty compelling, although I was pre-disposed to believe it. As the book concludes, modern knowledge economies are complex. Team work is almost universal. Any organisation wanting to do better – in any of the ways listed above – will be committed to diversity. This very clear and compelling book will help people consider specifically what shape their challenges and problems take and what kind of diversity will help address them. So the moral is not that HR departments should seek to hire identity diverse people for the sake of it, but that they understand the needs of their organisations and the mapping from identities to cognitive repertoires. But in any case, the outcome will be more diverse in every sense than it is currently.

Learning from books

It’s obvious why Camus’ The Plague came to my mind at the weekend: “[Rieux] … knew … that the plague bacillus never dies or disappears for good; that it can lie dormant for years and years…”

IMG_4288I read it again quickly in the past couple of days & flashed back to being so gripped by it as a young teen that I stayed up into the night reading it. As I finished, I noticed a blister on my arm, and ran to my bemused mum calling out that I had the plague. In the unheated house we lived in, we went to bed with cylindrical metal hot water bottles stuffed into old socks, & I’d failed to notice mine burning me through a hole in the sock. At that age, and being so literal minded, I didn’t spot the book’s metaphorical meaning….. As Camus says, there is much we can learn from books, if we pay attention.

FT Business Book longlist

The Financial Times Business Book of the Year longlist has just been published, and most of the titles sit in my two favourite categories: economics and technology. Even better, I’ve read five of the books already, and they are all excellent candidates, although I have my preferences. If I had to pick from these, I’d be torn between Lo and Tirole. But there are lots on the longlist still to read… quite a few of these are very tempting.

Here are the shortlisted books I’ve reviewed on this blog.

The Wisdom of Finance by Mihir Desai

The Great Leveler by Walter Scheidel (I don’t seem to have written a review of it, though I cite it here)

[amazon_link asins=’0691165025′ template=’ProductAd’ store=’enlighteconom-21′ marketplace=’UK’ link_id=’b6131034-7fff-11e7-98b2-e306b5666937′]

The other title I’ve read, having had the privilege of helping prepare the English edition, is

Economics for the Common Good by Jean Tirole; out in October, with superb insight into using economics in public policy, and also into the strengths and limits of economic research

[amazon_link asins=’0691175160′ template=’ProductAd’ store=’enlighteconom-21′ marketplace=’UK’ link_id=’dad2424a-7fff-11e7-95f3-5fcb61484d6e’]

Other minds

I’ve been dipping back into a lot of my collection on welfare economics, for various reasons. I.M.D. Little (A Critique of Welfare Economics) has a wonderfully spiky style, absent from modern academic writing (well, any kind of style really):

“It is clear that if one accepts behaviour as evidence for other minds, then one must admit that one can compare other minds on the basis of such evidence. Therefore those who ‘deny’ interpersonal welfare comparisons must deny the existence of other minds. The only possible alternative is that by some extraordinary kind of intuition, they can get to know that other minds exist but that the cannot know anything about them.”
