Platforms and information

I was quite excited by the prospect of reading Matchmakers and Market: The Revolutionary Role of Information in the Economy by Yi-Cheng Zhang. But it didn’t quite work for me, perhaps because the intended audience isn’t clear. The reason for excitement is clear: what the digital economy does is change the possibilities for the use of information in production and consumption. As the classic Hayek article observed, ‘the use of knowledge in society’ is the fundamental challenge of economic organisation. Yi-Cheng Zhang is a physicist and more relevantly the honorary director of Alibaba’s Complexity Research Centre. I hadn’t heard of this but it sounds like it should be delivering some very interesting insights.

However the book – very short – is written in a non-technical manner about how digital platforms operate. It’s key point is a concept labelled ‘infocap’, a sort of possibility frontier for the economic agent’s knowledge. There is an information asymmetry between individuals (who can’t know all there is to know about a firm’s products) and firms (who do know this but can’t know all about an individual’s range of preferences, although they can try to alter these). This is an interesting lens on the familiar platform economics but I think people who have read about platforms will not find much new, while although there are no equations the writing is a bit dense for non-specialists who haven’t read the platforms literature. (There are also loads of typos, so presumably the book wasn’t copyedited. I’m the kind of reader who feels the need to take up a pencil and correct these as I go.) I wish the book had actually been more formalized to highlight what might be new.

So, in short, I’d direct economists to the Belleflamme and Peltz text, The Economics of Platforms, and non-economists to a general read such as Platform Revolution by Marshall Van Alstyne, Geoffrey Parker and Sangeet Paul Choudary, or Cusamano, Gawer and Yoffe’s The Business of Platforms.

Facts about facts

There’s something wonderful about a book titled All The Facts. Ambitious or what? The subtitle narrows it down, a bit, to “A History of Information in the United States since 1870.” One country, one and a half centuries. Needless to say, it’s still ambitious in its scope, embracing not just the technologies of information management – from account books and filing cabinets to punch cards and the Internet – but also how information has been created and used across all aspects of life: housework, healthcare, factory work, national security, you name it. Boxes have headings such as “The car salesman as a knowledge worker in the 1980s” and “Growth in Medical Information in America: evolution in a doctor’s training 1870-1940”.

It’s a hefty tome, whose basic point is the central role information plays in modern society. I’m with the programme; for example, agreeing with such statements: “A company’s success, is based on its experiences, what knowledge or information it and its employees posess … what a company knows is the source of all potential, and indeed actual, increases in productivity.” (p94) Information ecosystems structure markets and the economy as a whole (p282).

Although I did read it through, it might be more appealing to some readers as a book to dip in to, or to refer to for some specific issues (such as information in medicine or in houeshold management). I found it to be – yes – stuffed with facts, and a mixture of enjoyable and excessive detail, depending on how interested I was in the specific examples. It brought to mind the scale and ambition of Vaclav Smil’s books on energy & other matters, which are similarly both engrossing and challenging reads.

What information, to whom – and do they want it?

For a bit of variety, I’ve been reading Bletchley Park and D-Day by David Kenyon, who is the Research Historian at Bletchley Park. The broad story of code-breaking at Bletchley Park during World War 2, and the contribution of Alan Turing along with many others, is now well-known. The aspect explored in this book is specifically about the intelligence provided ahead of and during the D-Day landings. This includes a lot of detail about the operation of the various bits of Bletchley Park and other arms of intelligence. In one sense, that makes it a sort of ‘inside the Beltway’ account: who reported to which officer, how the different branches of the armed services related to each other and so on will be details too far for general interest.

However, there is one kind of detail in this book that I found truly fascinating, and that is about how the flow of information was organised: coming into Bletchley Park, within its increasingly large and complex organisational structures, and going out to decision-makers in the UK central command, in the US, and of course in the field before and during the attack. For information flows are at the heart of the challenge of managing any complex organisation. And the ease and cheapness of digital information flows are translating now into a growing gap between businesses and other organisations that can make use of the information and those that can’t.

In other words, it wasn’t all about code breaking. One key role was played by (mainly) women graduates whose job was to provide a weekly Index of what intelligence had been unearthed and send that to the people who needed it. There was so much raw data – decrypted messages – that making sense of its importance became at least as important. These women didn’t have exciting new machines: just their own intelligence, pencils and index cards.

Another interesting point is about willingness to receive the intelligence. General Patton was all in favour but Montgomery was not: he thought the military alone should get the Ultra information and distrusted it because he knew Churchill and others in Government were getting it too. Luckily, he had a subordinate who paid attention to the Ultra messages received.

Anyway, I confess to skipping through some parts but overall really enjoyed the book. I have an appetite for anything about the Bletchley Park story. And what could be more relevant to thinking about information in organisations than an organisation whose whole raison d’être was information?

When being fair to others is efficient

The title had slightly put me off the new book by David Bodanis: The Art of Fairness: The Power of Decency in a World Turned Mean. I’m not in the mood for self-improvement, given that (a) it’s January, always the worst month of the year and (b) it’s lockdown – so more in the mood for gin and chocolate. Despite my rather truculent seasonal despondency, though, I really enjoyed reading it.

The title is misleading, I think. The book seemed to me to be really about the power of making sure you get the widest range of information possible, by listening to enough people with respect and treating them well enough that they say what they think – while at the same time retaining enough scepticism about their motives. Not so much ‘do as you would be done by’ fairness, more ‘efficiency wage’ fairness – the way you treat people structures their incentives. There’s also a flavour of Team of Rivals about the argument: if you don’t listen to your opponents, or those who disagree with you, reality will bite you at some stage.

The author has his own views, though, and describes this as fairness, or as decency.  The book is structured into two halves. The first is a series of stories about effective leadership, divided into exemplars of the three skills of listening, giving and defending. Most of these are not well-known people – such as Paul Starrett, who won the contract to build the Empire State Building, or Ursula Bower, a British woman who led a team of hill tribe warriors in the mountainous North of India against the Japanese in the second world war. These tales are told crackingly well, and I raced through these chapters.

The second half works a bit less well, although still a compelling read. It starts by contrasting Goebbels and Roosevelt when young, the experiences that shaped them and how they responded, and broadens out into why Roosevelt’s leadership paved the way for the Allied victory and America’s postwar success. Perhaps it’s inherently hard to get the optimal focal length when so many volumes have been written about both men and about the war.

The book then ends with a very nice section of ‘readings and reflections’, a reading list with notes providing a sort of meta-commentary on the theme of decency, or how to be a good leader (one of Aristotelian virtue) in any context.

All in all, highly recommended. It certainly cheered me through a couple of grim January evenings.41RKfm5a9SL._SY346_

 

Property is theft (and allocatively inefficient too)

We launched the Bennett Institute for Public Policy in Cambridge this week so it’s been a bit hectic. I still managed to read Radical Markets: Uprooting Capitalism and Democracy for a Just Society by Eric Posner and Glen Weyl. It’s extremely thought provoking and clearly brilliant – yet also barking mad. This is the territory of thought-experiment rather than policy proposal.

The basic idea is Proudhon (‘All property is theft!’). Any private ownership of property contains within it the seeds of market power. Worse, “Private ownership of any asset, except homogenous commodities, may hamper allocative efficiency.” A more efficient and more egalitarian arrangement is for all property to be in effect rented from the state, by current ‘owners’ stating what they think every item is worth, and paying a tax on that amount. At any time, somebody who values it more can bid it away from them; there are continuous auction markets. For homes, there might be a notice period so people can order their affairs. There might be exemptions for small items of sentimental value such as Grandma’s fountain pen. The revenues raised from the tax would be returned as a basic income to all citizens.

The authors want to Radicalise voting as well as ownership. In place of the one person one vote tyranny of the majority, they apply the auction principle to politics as well as markets. Everybody gets an allowance of ‘voice’ which they can allocate according to their political preferences and strength of feeling about the issues. There is a quadratic tapering so I’d need four voice tokens to vote twice and so on. They like the idea so much they’ve applied it to opinion polling to elicit more accurate views – and, they write, “We have patented the use of QV and related methods to solicit opinions digitially.”

After two introductory chapters, the book applies the broad concepts to some specific areas, including the high profile paper proposing ‘data as labour’: in other words, that we should be paid by digital data harvesters for providing our time and knowledge. Each of the chapters starts with a vignette of what the Radical Market future might look like. They’re all rather dystopian, and especially the one in the data as labour chapter. Every interaction between human and digital assistant is monetised. I’m an economist – I like markets – but don’t want every minute or keystroke to have a dollar sign attached. If a click on a Like button is worth 20 cents, would I start wondering whether it was worth telling my neighbour about the great new coffee shop, because she’s not going to pay me for it? Of course the current situation is unsatisfying, but I’m still unpersuaded by this potential solution.

The most interesting chapter is the one about the concentration of share ownership (in the US) in the hands of a small number of large institutional investors. The book argues persuasively that this diminishes competition. Antitrust concentrates on the corporations, but institutional investors dilute its effectiveness, “by knitting together the interests of the biggest firms that dominate any particular market.” Here there is a policy proposal worth thinking about: restricting institutional investors to holding a maximum of a 1% stake in companies in the same market; or as much of they want of one firm but then none of its competitors shares. Very interesting idea. Don’t see what it has to do with the Radical Markets conceit.

The book ends by reflecting on markets versus central planning, alluding to the socialist calculation debate. Markets “allocate resources in ways no present computer could match.” Prices are a uniquely efficient summary of information, but markets can be improved – by having them operate continuously. “The market is the appropriate computer to achieve the greatest good for the greatest number,” but its bugs need fixing so there are fairer outcomes. Even better, common ownership makes the market outcome more efficient too.

This does glide over the fact that – should the nirvana of constant online auctions be attained – the state is there in some sense as the owner of all property and redistributor of large tax revenues raised as a sort of rent from everyone for having temporary use of, well, everything. Nor does it touch on assets owned by foreigners, or owned overseas. In fact, the book doesn’t really discuss practicalities at all because it isn’t a real set of proposals.Thomas Piketty‘s global wealth tax has more chance of becoming a reality than the permanent revolution of ubiquitous Vickrey auctions.

However, Radical Markets certainly made me think, about property, information, power. Well worth reading.
