Spreading the thriving

Posted on by

Jan Eeckhout’s The Profit Paradox: how thriving firms threaten the future of work is a very good read. It’s a game of two halves (yes, someone in my household is permanently watching the football at the moment).

The first half (in fact parts 1 and 2) is a nice synopsis of the reasons the economy (mainly the US but others are covered) tend towards a) concentration across many markets and hence b) diverging fortunes of companies and their employees, and the places where people live. This covers the features of digital technology, superstar phenomena, agglomeration economies – these are familiar to anyone who has been keeping up with the literature, but I applaud how well the book is written. Hooray for an economist who can write so engagingly. This section documents the evidence on concentration and mark-ups, the growing divergence between companies in terms of productivity and profits, and the corresponding decline in the labour share as outsourcing of routine occupations (call centres, cleaners, admin) has progressed. Eeckhout argues that there is assortative matching such that pay and conditions are polarising between people with high value jobs in frontier firms and people with low value added jobs in their contractors.

The book’s focus is on the implications of market power for people as workers, rather than as consumers – although it also notes the excess pricing power too. In sum, it reduces wages, both directly through monopsony power in individual labour markets and also because of the the macroeconomic consequences: with so many people in contingent work with low pay, aggregate demand is inadequate. (Some) firms are doing well but the economy isn’t. And this is the heart of Eeckhout’s argument: “The effect of the tide of market power is lowering wages across the economy.” I find this link persuasive. While there are many economists looking at the elements of this story, the way they are combined here is enlightening.

The second half turns to the much harder question of what to do, starting with an affirmation that for all the disruption the new technologies are a good thing (this chunk reminded me a bit of my own Paradoxes of Prosperity, which first came out in September 2001 and not surprisingly was hardly noticed).

The recommendations boil down to: enforce labour standards; mandate more data openness; and beef up anti-trust policies. In particular (under the last heading) stop big tech making more acquisitions, regulate them rather than break them up (so as not to lose beneficial network economies), and assess market impacts in the round rather than firm by firm. (Tricky to implement but I do remember that in my days on the Competition Commission, as it then was, we often had to include a section of the report on ‘Features of the market’ – problems in concentrated markets do often spread beyond an individual transaction).

I’d agree with all these suggestions in the book but they add up to a meta-suggestion: find the political will to change the institutional architecture so that it delivers fairer outcomes. The technological tides won’t retreat but the effects depend on what institutions confront them. Is Lina Khan’s appointment in the US a sign of lasting change?

Finance and the world

Posted on by

One of the highlights of my career as a  financial journalist was a trip to the Chicago Board of Trade in its open outcry days. It must have been around 1993. I can still remember the physical sensation caused by the explosion of the noise of human voices shouting orders in the huge trading pits as soon as the bell rang. It was an extraordinary experience. But one shouldn’t romanticise open outcry. And as Donald Mackenzie records in Trading at the Speed of Light, one CME trader said to him after the closing bell had rung (this was in 2000): “Look at my glasses. They’re all dirty.” Flecked with spittle from the shouting melee.

I loved this book. I’ve been a keen follower of Prof Mackenzie’s research on high frequency trading since his early articles in the London Review of Books as well as a previous book, An Engine, Not A Camera. Prof Mackenzie describes his research endeavour as ‘material political economy’, and it concerns the interaction between the physics and (literal) construction of financial markets, and specifically HFT, and regulatory or political decisions, or power relations.

HFT is a world which is Einsteinian: the speed of light is the constraint on trade, and what traders (human or algorithmic) know about the market is determined by their physical location and physical connectivity: where are they, to the millimetre; how close to a geodesic curve is their communications connection (and is it fibre optic or wireless or microwave); is it raining (which interferes with certain parts of the radio spectrum more than others); to what extent have they programmed trading activities into hardware (chips and C++) for speed?

I’ve always been deeply fascinated by the physical dependencies and consequences of the online world. For example, I was right to predict in The Weightless World that – rather than the death of distance – digitalisation would enhance the agglomeration effects that concentrated people in certain places (we will see if this changes post-pandemic but I’d still reckon not.) Currently I’m somewhat preoccupied with where the internet is, and with the huge physical investments Big Tech companies have made, the weight of digital activity on climate and minerals.

Trading at the Speed of Light is an amazing, detailed account of why material reality matters for virtual outcomes, and conversely, in the financial markets. Everybody with the slightest interest in modern finance should read it (Prof Mackenzie helpfully flags sections that are technical enough to be readily skipped). The book is based on years’-worth of interviews and attending conferences and visiting remote data centres and masts, snapping photos.

The book describes the arms-race of speed and pushing ever-closer to physical limits. A key interview quotation appears mid-way: “I don’t think there’s any other industry than the finance industry that can pay for it ….It’s mind-numbing to look at this whole industry where you have a lot of people with extended training that spend night and day shaving nanoseconds. Where, if you could put that brainpower to something else, maybe somehthing different……”

Indeed. And yet the HFT we have today is the product of decisions taken by people, politicians persuaded by lobbyists. One of the things I learned from the book is that forex trading remains far more artisanal than share trading, albeit still automated. Alas, this was because of the political power of the banks involved rather than anybody’s deep foresight. Human decisions shape markets shape the world, but the consequences are rarely if ever forseen.

Who knows where it will all end (although, presumably, not well). The book ends by pointing out that ‘material political economy’ is the right lens to turn on both crypto (energy-devouring, CO2-spewing monsters) and the world of Big Tech with its datacentres and algorithmic advertising market. At least in these two cases, regulators are perhaps more aware of the societal challenges than their equivalents were in the early days of algorithmic share and futures trading. But it’s a good while since financial markets served their societies rather than predating on them.

My husband has written a terrific book

Posted on by

When Rory was writing Always On: Hope & Fear in the Social Smartphone Era I was firmly shut out of the process. He required none of my constructive criticism, just lots of cups of tea and the occasional, “How marvellous, darling.” Well, the book is out in a couple of weeks, the copies arrived, and I’ve been allowed to read it. And it’s terrific – a front row view of the key developments, the business of tech, and the social trends for good and ill this technology (only with us for relatively few years) has unleashed.

Rory & I recently celebrated our 31st wedding anniversary, so I lived through all these stories. I well remember the holiday in Mallorca almost torpedoed by his obsesssive phone calls; the embarrassing Google Glass episode; the endless new gadgets; and since last March as we’ve all been working from home have been able to hear most of the BBC tech team’s online editorial meetings. “Leo again!” we chorus when the phone rings at 7.45 am, or over lunch. Anyway, I didn’t need the book to know the ins and outs. It’s still a terrific read. Do buy it! It will make him happy and bring great cheer to the family dining table.

Baumol meets Marx

Posted on by

I read Jason Smith’s Smart Machines and Service Work: Automation in an Age of Stagnation because there was a positive discussion of it on Twitter. I’d describe it as a mash-up of Baumol (‘cost disease’) and Marx (‘exploitation’).

The first part of the book is a rant about technology and why today’s tech will not increase productivity. It channels Robert Gordon and criticises economists like Erik Brynjolfsson (or before him Paul David) for arguing there are delays between innovation and the productivity effects they produce.

I have the same problem with this as with Gordon’s magnum opus: it might turn out to be correct that today’s techs have no productivity impact, but focusing only on digital entertainment and communication devices is completely unpersuasive. Vaccines, hello? The wave of biomedical innovation like the development of mRNA vaccines has rested on the plunging cost of gene sequencing, enabled by computation applied to massive amounts of data. Lab benches, test tubes, and also computers. The transition to green energy supply will require large-scale computation to manage storage, networks and grids. Additive manufacturing has many potential applications including printing organs and tissues. These applications are genuinely slow to emerge: large additional investments in equipment are needed, the organisational and ethical hurdles are high, other discoveries might be required to make them economically viable. We’re lucky so much of the prior mRNA research had been done before 2020.

Anyway, the book halfway through then turns to the growth of the service sector, the automation of routine tasks, and the debate about the potential impact on jobs. It looks back, too, at the well-known decline in middle-income jobs and growth of the contingent workforce. Having introduced Baumol’s familiar ‘cost disease’, it then turns to a Marxist analysis. Having never learned Marxist economics I found this quite interesting but heavy going, as it has its own jargon. Still, it is surely right to consider the impact of automation in the context of power struggles, or class conflict.

The book has some sections where it pauses to ask what is actually meant by ‘productivity’, a question of evergreen interest to me. It touches here on the issue of time use and time saving in services, and on activities crossing the production boundary, making it hard to measure ‘true’ productivity. As it points out, many previously household (uncounted) activities became marketed during the 20th century (‘commoditised’), and are often low-pay and precarious. However, the book then veers back to the more abstract class struggle.

All in all, I found the book quite interesting for its novel (to me) perspective, and it is well written. But much of the (non-Marxist) economic literature it draws on will be familiar to many people enticed by the subject matter. What it adds to the technology debate is, quite rightly, the issues of power and deregulation of the labour market,  beyond discussions of gig platforms. But it didn’t tell me anything new about the productivity puzzle.

Where *is* the internet?

Posted on by

I’m not sure ‘read’ is the right verb for Networks of New York by Ingrid Burrington, but I looked at it this week. It’s a sketchbook of various bits of internet kit from cables below ground to antennae on rooftops, with notes about the physical kit that makes up the system getting people online, and about the ownership of the kit. I’ve been growing  slightly obsessed by how little is known about the physical internet. So far, James Ball’s The System and Andrew Blum’s Tubes are the only entries on my list of books about this. I was pleased to find out about Ingrid Burrington, who has a number of articles on this and related subjects. But if anybody knows of other books or papers about the physical infrastructure of the internet and the ownership of it (especially for the UK) I’d love to know.
