Milan Kundera wrote his The Book of Laughter and Forgetting in 1979, a few years after moving to France and the same year he had his Czech citizenship revoked. His books had all been banned in Czechoslovakia in 1968, as most of them poked fun at the regime in one way or the other. The Book of Laughter and Forgetting was no exception, focusing, via seven stories, on what we choose to forget in history, politics and our own lives. One of the themes is a word which is difficult to translate into English: litost.

Litost seems to mean an emotional state of feeling of being on your own suddenly brought face to face with how obvious your own hopelessness is. Or something to that effect. Kundera explored several aspects of litost at length in the novel. However, for all the difficulties of describing it exactly, litost feels like a useful word for our times, our politics and our economics.

I want to focus on two specific examples of forgetting and the sudden incidents of litost which have brought them back into focus.

The first, although not chronologically, would be the pandemic. There are several articles around suddenly about the lessons we have not learnt from the pandemic, to mark the fifth anniversary of the first lockdown. Christina Pagel, backed up by module 1 of the Covid-19 Inquiry, reckons:

Preventing future lockdowns requires planning, preparation, investment in public health infrastructure, and investment in testing, virology and medical research…

She takes issue with some of the commentary as follows:

But the tenor of reporting and public opinion seems to be that “lockdowns were terrible and so we must not have lockdowns again”. This is the wrong lesson. Lockdowns are terrible but so are unchecked deadly pandemics. The question should be “lockdowns were terrible, so how can we prevent the spread of a new pandemic so we never need one again?”.

However the stampede to get back to “normal” has mitigated against investing in infrastructure and led to a massive reduction in testing and reporting, and the Covid-19 Inquiry has given the government cover (all questions can just be responded to by saying that the Covid Inquiry is still looking at what happened) to actively forget it as quickly as possible. Meanwhile the final module of the Covid-19 Inquiry is not due to conclude until early 2026, which one must hope is before the next pandemic hits. For which, as the former Chief Scientific Adviser and other leading experts have said, we are not remotely prepared, and certainly no better prepared than we were in 2020.

It is tempting to think that this is the first major recent instance involving the forgetting of a crisis to the extent that its repetition would be just as devastating the second time. Which is perhaps a sign of how complete our collective amnesia about 2008 has become.

Make no mistake, 2008 was a complete meltdown of the core of our financial system. People I know who were working in banks at the time described how even the most experienced people around them had no idea what to do. Alistair Darling, Chancellor of the Exchequer at the time, claimed we were hours away from a “breakdown in law and order”.

According to the Commons Library briefing note from October 2018, the Office for Budget Responsibility (OBR) estimates that, as at the end of January 2018, the interventions had cost the public £23 billion overall. The net balance is the result of a £27 billion loss on the RBS rescue, offset by some net gains on other schemes. Total support in cash and guarantees added up to almost £1.2 trillion, including the nationalisation of Northern Rock (purchased by Virgin Money, which has since been acquired by the Nationwide Building Society) and the Bradford & Bingley (sold to Santander) and major stakes in RBS (now NatWest) and Lloyds. Peak government ownership in these banks is shown below:

If you read the Bank of England wacky timeline 10 years on from 2018, you will see a lot about how prepared they are to fight the last war again. As a result of this, cover has been given to actively forget 2008 as quickly as possible.

Except now various people are arguing that the risks of the next financial crisis are increasing again. The FT reported in January on the IMF’s warnings (from their Global Financial Stability Report from April 2024) about the rise in private credit bringing systemic risks.

Meanwhile Steve Keen (one of the very few who actually predicted the 2008 crisis) in his latest work Money and Macroeconomics from First Principles, for Elon Musk and Other Engineers has a whole chapter devoted to triggering crises by reducing government debt, which makes the following point:

A serious crisis, triggered by a private debt bubble and crash, has followed every sustained attempt to reduce government debt. This can be seen by comparing data on government and private debt back to 1834.

(By the way, Steve Keen is running a webinar for the Institute and Faculty of Actuaries entitled Why actuaries need a new economics on Friday 4 April which I thoroughly recommend if you are interested)

Which brings us to the Spring Statement, which was about (yes, you’ve guessed it!) reducing government debt (or the new formulation of this “increasing OBR headroom”) and boosting GDP growth. Watching the Chief Secretary to the Treasury, Darren Jones, and Paul Johnson from the IFS nodding along together in the BBC interviews immediately afterwards, you realised how the idea of allowing the OBR to set policy has taken hold. Johnson’s only complaint seemed to be that they appeared to be targeting headroom to the decimal point over other considerations.

I have already written about the insanity of making OBR forecasts the source of your hard spending limits in government. The backdrop to this Statement was already bad enough. As Citizens Advice have said, people’s financial resilience has never been lower.

But aside from the callousness of it all, it does not even make sense economically. The OBR have rewarded the government for sticking to them so closely by halving their GDP growth projections and, in the absence of any new taxes, it seems as if disabled people are being expected to do a lot of the heavy lifting by 2029-30:

Part of this is predicated on throwing 400,000 people off Personal Independence Payments (PIPs) by 2029-30. According to the FT:

About 250,000 people, including 50,000 children, will be pushed into relative poverty by the cuts, according to a government impact assessment.

As Roy Lilley says:

We are left standing. Abandoned, to watch the idiocy of what’s lost… the security, human dignity and wellbeing of our fellow man, woman and their family… everything that matters.

As an exercise in fighting the last war, or, according to Steve Keen, the wars successive governments have been fighting since 1834, it takes some beating. It was litost on steroids for millions of people.

So what does the government think these people are going to fill the income gap with? It will be private debt of course. And for those in poverty, the terms are not good (eg New Horizons has a representative APR of 49% with rates between 9.3% APR and maximum 1,721% APR).

And for those who can currently afford a mortgage (from page 47 of the OBR report):

Average interest rates on the stock of mortgages are expected to rise from around 3.7 per cent in 2024 to a peak of 4.7 per cent in 2028, then stay around that level until the end of the forecast. The high proportion of fixed-rate mortgages (around 85 per cent) means increases in Bank Rate feed through slowly to the stock of mortgages. The Bank of England estimates around one-third of those on fixed rate mortgages have not refixed since rates started to rise in mid-2021, so the full impact of higher interest rates has not yet been passed on.

So, even before considering the future tax increases the FT appears to be expecting, the levels of private debt look like they will shoot up very quickly. And we all know (excluding the government it seems) where that leads…

The Future

This is the 200th post from this blog, so I want to talk about The Future.

*The Planetary Solvency Dashboard https://global-tipping-points.org/risk-dashboard/*

No. Not that future. Scary though it is.

I want to talk about The Future by Naomi Alderman. I read it last year, after wandering around the Hay Festival bookshop moaning that they don’t do science fiction and then coming across Naomi’s book and realising I had just missed her being interviewed. Then I watched the interview and bought both The Future and The Power (which I will talk about at some future date, but which is equally terrific).

The book is about Lenk Sketlish, CEO of the Fantail social network, Zimri Nommik, CEO of the logistics and purchasing giant Anvil, Ellen Bywater, CEO of Medlar Technologies, the world’ most profitable personal computing company, and the people working for them, and the people linked with those people. Zimri, Ellen and Lenk are at least as monstrous as Jeff, Sundar, Elon, Tim and Mark. And they are all preparing for the end of the world.

(If you need to remind yourself what Elon, Jeff, Mark and Sundar all look like milling around, below is a link to Trump’s inauguration:

https://apnews.com/video/jeff-bezos-district-of-columbia-elon-musk-inaugurations-united-states-government-486ab2a989e94aaa8c9afec15bebeb51)

Anvil is set up with alerts for signs of the end of the world being reported anywhere: giant hailstones, plague of locusts, Mpox, rain of blood which turned out to be a protest for menstrual equity involving blood-soaked tampons being thrown at Lenk and co as they emerged from a courthouse in Washington. The information Zimri, Ellen and Lenk have on everybody else in the world makes them feel all seeing, all hearing, all knowing. Combined with riches unknown to anyone before in history it makes them feel invulnerable, even to the end of the world, even to each other. Which turns out, of course, to be their decisive vulnerability.

It takes in survivalism, religious cults and wraps it all up in a thriller plot which is absolutely the kind of science fiction you want to be reading now instead of listening out for the latest antics of the horse in the hospital. And it was all written over a year before Elon even started with DOGE. The Future by Naomi Alderman is a fantastic read, particularly if you would like to see someone like Musk get an appropriate end to his story. I obviously won’t spoil it by saying what that is, but I don’t think I would be giving anything away by saying rockets are involved!

Going nowhere faster

*Risk trajectory (black circle) shows the anticipated future state for the risk in 2050. Current risk position in grey. Source:* https://actuaries.org.uk/planetary-solvency

The excellent report from the Institute and Faculty of Actuaries and the University of Exeter Planetary Solvency – finding our balance with nature splits the risk trajectories into four sections: Climate, Nature, Society and Economy. I have focused on the Society one above as, in my view, this is the reason we are interested in all of the other ones. According to the Planetary Solvency report, we are on track for a society in 2050 described as follows:

Nature and climate risk trajectories will drive further biophysical constraints including stresses on water supply, further food supply impacts, heat stress, increased disease vectors, likely to drive migration and conflict. Possible to Likely risk of Severe to Decimation level societal impacts, with increasingly severe direct and indirect consequences of climate and nature risks driving socio-political fragmentation in exposed and vulnerable regions.

So what are we doing about it? Well the United States has just voted in Donald Trump as President. There was a flurry of executive orders issued in his first week (with the appropriate caveats about how many of these might actually be implemented), the climate-related ones of which are neatly summarised here by Bill McKibben:

The attacks on sensible energy policy have been swift and savage. We exited the Paris climate accords, paused IRA spending, halted wind and solar projects, gutted the effort to help us transition to electric vehicles, lifted the pause on new LNG export projects, canceled the Climate Corps just as it was getting off the ground, and closed the various government agencies dedicated to environmental justice. Oh, and we declared an “energy emergency” to make it easier to do all of the above.

Timothy Snyder has written about how to respond to tyranny in your own country. What is happening currently in the United States is threatening tyranny for many (as Robert Reich lists here):

The government now recognizes only two “immutable” genders, male and female. Migrants (now referred to as “aliens”) are being turned away at the border. Immigration agents are freed to target hospitals, schools, and churches in search of people to deport. Diversity efforts in the federal government have been dismantled and employees turned into snitches. Federal money will be barred from paying for many abortions.

The first thing you should do, according to Timothy Snyder, is to not obey in advance.

Most of the power of authoritarianism is freely given. In times like these, individuals think ahead about what a more repressive government will want, and then offer themselves without being asked. A citizen who adapts in this way is teaching power what it can do.

And how did we respond to all of this in the UK? Well Keir Starmer was keen to tell The Donald that we were deregulating to boost growth in their first phone call. His reward for this was the story that Trump thought he was doing a good job. Supposedly an endorsement from the “Drill Baby Drill” guy is the proper corrective from being told he should be locked up by the Nazi salute guy.

And then there were the actions on the environment. From the talking out of the Climate and Nature Bill which sought to meet new legally binding targets on climate change and protect nature. To a housing policy which will be both hugely environmentally destructive and fail to make houses more affordable. To announcing the intention to overhaul the planning rules, in the upcoming Planning and Infrastructure Bill, to reduce the power of people to object (and, as the Conservatives’ restrictions on protest have not been lifted, subsequently bang them up for years on end if we subsequently demonstrate about it) so that global firms would think that the UK was a “great place to invest” .

And then today we had Rachel Reeves’ big speech. Approval for developing the third runway at Heathrow, as had been extensively trailed, and the creation of “Europe’s Silicon Valley” between Oxford and Cambridge were the main announcements. There was quite a lot of talk about investment in sustainable aviation fuel (which means biofuels, the benefits of which have already been shown to be wiped out by rising demand).

And as for the Silicon Valley idea, I am not sure we want one. First there is the lack of real innovation despite the excellent game they talk. And second, is it going to be the authoritarian nightmare that the Californian one is turning into? The early signs are not good. Just last week Marcus Bokkerink, the Chair of the Competition and Markets Authority (CMA), was replaced by Doug Gurr, until recently Jeff Bezos’ head of Amazon UK. So not exactly standing up to Technofeudalism then.

According to Cory Doctorow:

Marcus Bokkerink, the outgoing head of the CMA, was amazing, and he had charge over the CMA’s Digital Markets Unit, the largest, best-staffed technical body of any competition regulator, anywhere in the world. The DMU uses its investigatory powers to dig deep into complex monopolistic businesses like Amazon, and just last year, the DMU was given new enforcement powers that would let it custom-craft regulations to address tech monopolization (again, like Amazon’s).

But it’s even worse. The CMA and DMU are the headwaters of a global system of super-effective Big Tech regulation. The CMA’s deeply investigated reports on tech monopolists are used as the basis for EU regulations and enforcement actions, and these actions are then re-run by other world governments, like South Korea and Japan.

When you see Trump flanked by Bezos and the other Tech Bros at his inauguration, it certainly feels like we are obeying in advance. Rachel Reeves’ speech had an enormous increase in energy demand implicit in pretty much every measure announced, which is expected because, GDP (the thing she is looking to boost) and energy consumption have been in lockstep forever. This is the implication of prioritising GDP growth over everything else.

What were missing were both a compensatory increase in renewable energy capacity and/or a reorganisation of our economy away from energy intensity. The problem for the government is that the latter would not increase GDP, so instead we get into the absurd position of the Business Secretary saying we “cannot afford to not build runways”.

However it seems that when the motivation is big enough (in this case to dispute the assertion that the Russian economy is doing well in wartime despite the official statistics, which the EU really needs to do in order to continue to make the case for sanctions) alternative ways to measure the economy can be found. In section 3.2 we find this:

The general assumption of connecting GDP growth to making people better off is not relevant in this situation, which should be included in any discussion of how the Russian economy is doing.

What is interesting about this analysis is that:

a. It is carried out by the kind of orthodox economists (the Stockholm Institute of Transition Economics) who believe GDP would be a good index to use in normal circumstances; and

b. They are saying this even if the GDP figures published by Russia are technically accurate. As they go on to say:

What this analysis suggests is that if we believe in official Russian statistics, then Russia has economic capacity to sustain current policies in the short run, a conclusion shared with many other observers. We also find, though, that beyond the GDP numbers, the redirection into a war economy is already putting pressure on all sectors not directly involved in the war, causing internal macroeconomic imbalances, increasing risks in the financial sector, and eroding export revenues and existing reserves. Short term growth is kept up by a massive fiscal stimulus, but the impact is mitigated by necessary monetary contraction to deal with inflationary pressures, and structural factors (demographics, weak property rights) limiting the possible economic response to the stimulus.

Some of which sound familiar closer to home – “necessary monetary contraction” (things we cannot afford) and “increasing risks in the financial sector” anyone?

We are currently facilitating a world where the only capacity we are increasing is to fly over the climate-ravaged areas of the globe and their fleeing populations. Fly Baby Fly is not going to get us anywhere we want to go.

Horizon and its implications for us all

Copyright ©Steve Bell 2009/All Rights Reserved e.mail: belltoons@ntlworld.com tel: 00 44 (0)1273 500664. Reproduced by kind permission of Steve Bell https://www.belltoons.co.uk/bellworks/index.php/leaders/2009/2913-16-10-09_BOINGUSES

We have been here many times before, even in recent memory. The 2008 banking crisis, memorably immortalised by the Steve Bell cartoon above; the MPs’ expenses scandal the following year; the successive disappointments of Brexit; and now the the Post Office Horizon scandal. All of these had in common an initial public expression of outrage, followed by loud condemnations of aspects of it from within the Establishment, followed by a series of measures which generally failed to change anything substantive. So the ring-fencing legislation brought in to isolate the risk taking within banking from retail customers has steadily been lobbied against and is now gradually being unravelled. MPs continue to have expenses scandals. I don’t know how to encapsulate in a sentence the Muppet Show of how the Establishment has been trying to deal with Brexit since 2016. And now this.

The Post Office scandal seems to be being discussed everywhere: beyond the TV, radio and social media, it is in the pub, the supermarket queue, in families and workplaces. The Establishment condemnation is already underway, as pithily summarised by Marina Hyde here. I do not really care about the implications for the honours lists, but very much hope that the sub-postmasters and sub-postmistresses get the compensation they are seeking. However this time the response cannot stop there.

As David Allen Green has written in Prospect today (with a great overview of what has happened from a legal point of view), the scandal also represents a failure of the legal system. This was partly caused by the repeal, in 1999, of the part of the Police and Criminal Evidence Act 1984 which presumed in favour of individuals rather than computer systems. This has been particularly unfair in these cases as the evidence defendants needed to show that Horizon was at fault often remained undisclosed by the Post Office. It was also caused by the Post Office’s eagerness to pursue private prosecutions.

Coincidentally, I came across the concept of private prosecutions a couple of weeks ago while reading the excellent Butler to the World: How Britain became the servant of tycoons, tax dodgers, kleptocrats and criminals by Oliver Bullough (which also suggested to me that I should revisit the issue of Scottish Limited Partnerships soon, but I digress). As Oliver points out:

Under measures introduced in the post-2010 austerity agenda, defendants…have no prospect of reclaiming their expenses from public funds if they are convicted. Even if they’re acquitted, they can only get their expenses back if a request for legal aid has previously been turned down…Meanwhile, private prosecutors – whether individual or companies – can claim back all reasonable expenses if they lose. Financially speaking, a private prosecution is a one-way bet. As long as you can afford the upfront cost of bankrolling the case, you’ll get your money back because under common law you are acting on behalf of the Crown.

David Allen Green has called for private prosecutions to be abolished, which I would agree with. But I also think the burden of proof needs to be returned to the operators of computer systems in what I predict will become increasingly frequent human-expert system disputes in the future. In fact we need to go further than that and have a full public consultation into what legal protections individual humans will need in a world increasingly driven by decisions and calculations made by non-human systems.

Over seven years ago I wrote an article in response to Cathy O’Neil’s excellent Weapons of Math Destruction, where she set out the case against devolving important decisions to mathematical models without adequate feedback loops. I said then (with an Oppenheimer reference too!) that:

If mathematical models are to be the dominant regulatory tool of a financial world, and of the consultancies and financial firms competing in that world, then the time will come when mankind will curse the names of the highly paid professionals who followed inappropriate rules rather than exercising their own expert judgement when it mattered.

It is starting to look like we may be there already unless we act fast.

Sleaford-upon-Sea and the future none of us wants

The year is 2100. Earth is approaching a peak population of 9.5 billion people. Despite some notable progress in decarbonising our activities and more progress on carbon capture of various types than expected 80 years ago, overall we have not managed to shift much off the Intergovernmental Panel on Climate Change (IPCC) middle-of-the-road shared socioeconomic pathway (SSP2). Some countries have done much better than others, with income inequality a problem both within and between them. Carbon emissions stayed fairly level until 2050 before starting to fall, but net zero has still not been achieved.¹

Temperatures have risen by 2.7 degrees compared to pre-industrial levels. Africa has split between a north which has seen a recovery of rainfall and a south which is no longer habitable for humans. The Indian monsoon rains have failed. The Himalayan glaciers providing the waters of the Indus, Ganges and Brahmaputra, the Mekong, Yangtze and Yellow rivers have reduced by 90% from their pre-industrial levels.

The Amazonian rain forest basin has dried out completely. In Brazil, Venezuela, Columbia, East Peru and Bolivia life has become increasingly difficult due to wild fires. Drought is now permanent in the sub-tropics and Central America. Australia has become the world’s driest nation.

In the US Gulf of Mexico high sea temperatures drive 180+ mph winds.² Flooding is widespread with sea levels having risen by 0.6 metres on average compared to 2020.³ Many plant species have become extinct as they were unable to adapt to such a sudden change in climate.

Food prices continue to soar, with temperatures, droughts and the inundation of arable land adversely affecting many crops. Massive migrations have led to increasingly severe military and police responses from the most popular destination countries. There is fear that we have not yet seen the end of the terrible costs of climate change, with temperatures continuing to rise.

England has a new Eastern coastline, which became a certainty once the decision was taken that the cost benefit analysis did not justify the expense on the massive coastal defences which would have been required to prevent it. Sleaford is now a seaside town. Birmingham is the only major city which has not been significantly affected by sea level rise⁴ and there are calls for the capital to be moved there. However London hangs grimly on following the failure of the Thames Barrier in the 2040s. An Intertidal Property Pricing Index (IPPI) has sprung up, which sucks in money as investors bet on the development opportunities in the aftermath of the catastrophe.⁵

This, or something like it, is the future we are currently on track for but none of us wants. So let’s change the trajectory.

Could climate change slash global GDP by 18%? It’s much worse than that

05. May 2021 · Write a comment · Categories: Actuarial, Climate Change, COVID-19, Economics, Prediction, Risk

Last week, the news from the Actuary magazine was that climate change could slash global GDP by 18%. This was based on a Swiss Re report, the economics of climate change, from which the analysis above is taken.

According to the report, “The current trajectory of temperature increases, assuming action with respect to climate change mitigation pledges, points to global warming of 2.0–2.6°C by mid-century.” It was unclear why they had decided to stop at 2050, when current commitments continue to push temperatures up until 2100. And the scenarios from the IPCC’s AR5 Synthesis Report (see below) show that the path we are currently on diverges far more considerably from the Paris agreements after 2050. Climate effects are very long-term and many of the impacts of a 2-3°C warming would be irreversible ones, ensuring continuing losses at similar or greater levels for decades to come, and that is before we even consider the much higher probabilities of feedback effects: from the melting of the permafrost, additional methane releases, loss of Amazonian carbon and the loss of the albedo reflectivity of Arctic ice. The Swiss Re report makes clear that is has not considered these.

You might notice that there is a separate column to the left, in a different colour, with the title “Well-below 2°C increases” and sub-title of “Paris target”. It is actually an agreement which 189 countries have signed up to, including the UK. As the Paris Agreement says (Article 2 Point 1):

This Agreement, in enhancing the implementation of the Convention, including its objective, aims to strengthen the global response to the threat of climate change, in the context of sustainable development and efforts to eradicate poverty, including by:
(a) Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature
increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change;

There has been some debate over whether the Agreement is aiming for 1.5°C warming with a 50% chance of staying below it, or for “well below” 1.5°C similar to the 2°C goal with a 66% chance of avoiding more than 1.5°C warming, but the modelling used for the next IPCC report has adopted the latter definition. Either way, I cannot see why Swiss Re has decided to put the Paris Agreement targets in a different column from what it calls the “likely range of temperature gains” as if those we have committed to are no longer feasible to aim at.

In saying this, I do not underestimate the massive challenge of keeping to the Paris target. As Mark Lynas says in Our Final Warning, at the end of 2018 over 1,000 GW of additional fossil-fuelled electrical power generation capacity was planned, permitted or already under construction around the world, equivalent to adding an additional 188 Gt CO2 into the atmosphere to the 658 Gt already baked in from existing infrastructure, which gives a total of 846 Gt of CO2 not including impacts from deforestation, agriculture and future land-use change. This compares to a future carbon budget as estimated at the end of 2018 by the IPCC (although estimates of this vary considerably) of 420 Gt of CO2 (or 1,170 Gt of CO2 for 2°C warming). So an extraordinary change of direction is required and we should be very cautious of getting anywhere near these limits when we do not know precisely where they are.

Which brings me onto the modelling of economic impacts. The first thing to say is that modelling in terms of impact on GDP, while guaranteed to get the attention of the financial community, is perhaps not the best way of communicating the devastation of runaway climate change.

In the summary of Mark Lynas’ excellent book Six Degrees: Our Future on A Hotter Planet , which summarised the scientific consensus already arrived at by 2007, the three degree increase for which damages are being estimated is expected to lead to Africa […] split between the north which will see a recovery of rainfall and the south which becomes drier […] beyond human adaptation. Indian monsoon rains will fail. The Himalayan glaciers providing the waters of the Indus, Ganges and Brahmaputra, the Mekong, Yangtze and Yellow rivers [will decrease] by up to 90%. The [IPCC] in its 2007 report concluded that all major planetary granaries will require adaptive measures at 2.5° temperature rise regardless of precipitation rates.[and] food prices [will] soar. Population transfers will be bigger than anything ever seen in the history of mankind. [The feedback effects from the] Amazon rain forests dry[ing] out and wild fires develop[ing] [will lead] to those fires [releasing] more CO2, global warming [intensifying] as a result, vegetation and soil begin[ning] to release CO2 rather than absorb[ing] it, all of which could push the 3° scenario to a 4°-5.5° [one]. The recent update to this: Our Final Warning, describes “entering the three-degree world means we are now living in a hotter climate than any experienced on Earth throughout the entire history of our species”. These impacts, which are likely to pose existential risks for many, appear totally inconsistent with the economic loss modelling shown above.

In his 2020 paper, The appallingly bad neoclassical economics of climate change (apologies, Journal access required), Steve Keen says in the abstract:

Forecasts by economists of the economic damage from climate change have been notably sanguine, compared to warnings by scientists about damage to the biosphere. This is because economists made their own predictions of damages, using three spurious methods: assuming that about 90% of GDP
will be unaffected by climate change, because it happens indoors; using the relationship between temperature and GDP today as a proxy for the impact
of global warming over time; and using surveys that diluted extreme warnings from scientists with optimistic expectations from economists. Nordhaus has misrepresented the scientific literature to justify using a smooth function to describe the damage to GDP from climate change. Correcting for these errors makes it feasible that the economic damages from climate change are at least an order of magnitude worse than forecast by economists, and may be so great as to threaten the survival of human civilization.

There follows a demolition of the methodologies employed by Nordhaus and others in this field. To be fair to the Swiss Re report, some of the criticisms in Keen’s paper appear to have been borne in mind when constructing their model, eg:

A shortcoming of our model build so far is that some economic impacts are linearly estimated: non-linearities are not adequately captured. We use multiplicative factors of 5 and 10 to simulate the increasing severity of outcomes from nonlinearities… Importantly, the framework does not consider
tipping points, events such as the partial disintegration of ice sheets, biosphere collapses or permafrost loss, that pose a threat of abrupt and irreversible climate change. This is because it is thought that tipping points will materialise well after our model horizon of mid-century only.

And as the Swiss Re report also acknowledges:

It is likely that the estimated impacts of GDP damages from climate change will rise as existing modelling develops to incorporate economic linkages in trade, migration and other channels, and to generalise the results to multiple countries.

And they are getting criticisms from the usual suspects of climate denial, eg Bjorn Lomberg on Twitter here, that even their attempts to date to quantify the uncertainties caused by non-linearity are a step too far.

And yet there remains a problem with these analyses in that they fail to capture existential risk. One of the things Steve Keen points out in his paper is the different attitude Nordhaus found towards estimating damages from climate change in natural scientists as opposed to economists. Natural scientists typically estimated the damage at 20-30 times higher than economists and some refused to cooperate with the exercise at all:

I must tell you that I marvel that economists are willing to make quantitative estimates of economic consequences of climate change where the only measures available are estimates of global surface average increases in temperature. As [one] who has spent his career worrying about the vagaries of the dynamics of the atmosphere, I marvel that they can translate a single global number, an extremely poor surrogate for a description of the climatic conditions, into quantitative estimates of impacts of global economic conditions.

But how do you calibrate what is clearly a complicated model that Swiss Re and Moody’s have constructed for this analysis? Obviously we all have a very recent GDP fall in our minds at the moment – here is a summary from the UK Commons Library of Economic Indicators as at 30 April 2021 (themselves sourced from OECDstat and Eurostat):

This shows an almost identical GDP fall of 10.5% year on year in Q2 2020 for the OECD as predicted in the event of a 3.2°C warming, although it has bounced back pretty quickly since. For a longer term view of the global data, Our World In Data have an Annual growth in GDP per capita graph which runs from 1961 to 2017 (see below).

One very large GDP fall which stands out in the data here is the 26.5% fall in China in 1961. This was towards the end of the China’s Great Famine, in which approximately 3 million people died of starvation over a 3 year period. This certainly qualifies as an existential event and Swiss Re’s modelling suggest something of similar proportions in Asia and Africa at 3.2°C warming.

The biggest danger in all of this is that rich countries will look at a 10.6% reduction in GDP (at 3.2°C warming) and think this liveable with and adaptable to for their populations. After all, Simon Wren Lewis calculates that the austerity policies between 2010 and 2018 in the UK reduced GDP by nearly half of this amount every year for at least the second half of this period, compared to where it would have been without these policies, with an estimated cumulative loss of 15.9% of GDP. An 18.1% overall world average loss, however, effectively means more than a 25% loss for the rest of the world outside the OECD, as the OECD accounts for around half of the world’s total GDP which, even if we did not allow for the acknowledged likelihood that these are underestimates, is still in the Chinese Famine category of disaster and neither liveable with nor adaptable to.

We are already seeing vaccine nationalism carve up the world between rich and poor countries, with up until last month only 0.3% of the vaccines administered around the world having gone to people in low-income countries. This is likely to reduce the ability of poorer countries to be represented properly at this year’s COP26 when it frames a global response to the climate change which will affect them so disproportionately. And the losses if we do not act will be measured in far more frequent floods and sea level rise, extreme storms and heatwaves, crop failures, water and food shortages and mass migration on a scale we have never seen before, not GDP.

Could climate change slash global GDP by 18%? It’s much worse than that.

Hope-over-Experience is a comfortable place to live in…for now

There is a particular variety of We Know Zero graphs that look like this one – showing an experience of a steady increase in something (usually bad, but not always) up until now, followed by a projection of that thing falling in the future. My wife Marsha suggested I call them Hope-over-Experience graphs, which seems to suit them very well.

Such diagrams are often very comforting for those who want to maintain the status quo. Let’s look at three such curves in particular (the excellent Doughnut Economics by Kate Raworth has alerted me to the first two of these).

The Kuznets Curve

There is a considerable body of evidence, most notably from Kate Pickett and Richard Wilkinson, that inequality impacts most health and social problems adversely, to the detriment of all socio-economic groups, but what is to be done about it? Enter our first Hope-over-Experience graph. In this case the x-axis is actually income per capita, but to the extent that this is something expected to increase with time I don’t think this matters too much. The y-axis is inequality. It was originally proposed by Simon Kuznets (the inventor of GDP) in his 1955 paper Economic Growth and Income Inequality (my apologies, but you will need journal access to read this) based on data from England, Germany and the United States from 1875 onwards, and the belief that economic growth will automatically deal with inequality has been a powerful influence on economic policy at the World Bank and elsewhere since.

However, more recent data has shown the patterns suggested by this limited original data set are no longer correct, if indeed they ever were. Thomas Piketty and Emmanuel Saez, in their 2001 paper Income Inequality in the United States 1913-1998, state:

In particular, the evidence presented in this paper, together with the evidence on France by Piketty (2001a, 2001b) and the U.K. by Atkinson (2001),
strongly suggest that there was no such thing as a “spontaneous”, Kuznets-like decline of inequality in developed countries during the first half of the 20th
century. The inequality decline was to a large extent accidental (depression, inflation, wars) and amplified by political factors (progressive taxation). This does not mean that the current rise of inequality will not be followed by a mechanical downturn during the first few decades of the 21st century: this is simply saying that such a mechanical downturn apparently never occurred in the past.

Their data suggests a curve which looks like this instead:

The Environmental Kuznets Curve

This was first proposed by Gene Grossman and Alan Krueger in 1994 in their working paper Economic Growth and the Environment, which suggested that there was an eventual inverse relationship between pollution and income per capita, with a turning point mooted at around $8,000. Most of their graphs are not quite as U-shaped as the Kuznets Curve, but this nonetheless has come to be known as the Environmental Kuznets Curve.

However, in 2016, the international industrial ecology research community and United Nations Environment agreed on a comprehensive data set for global material extraction and trade covering 40 years of global economic activity and natural resource use, which led to several papers including the UNEP Global Material Flows and Resource Productivity: A Report of the International Resource Panel (again apologies but journal access needed). Their graph of material extraction instead looked like this:

The Human Development Index (HDI) is the geometric average of 3 indices: Gross National Income, Health and Education. An optimum score of 1 is achieved where life expectancy is 85 or more years, adult literacy is 100%, school enrolment is 100% and the Gross National Income is US$40 000 or more per person per year in purchasing power parity. So again, this is not very supportive of a reduction in material footprint with increased wealth.

Which brings us to the third graph, often cited as an argument for why one of the most obvious ways to reduce inequality rather than just focusing on average income per capita, ie make taxation more progressive, is pointless.

The Laffer Curve

The story of the Laffer Curve, dating from the 1970s, is recounted by Arthur Laffer himself here. It plots tax rates against tax revenues to indicate that there is a tax rate beyond which tax revenues actually reduce. As he says:

The Laffer Curve itself does not say whether a tax cut will raise or lower revenues. Revenue responses to a tax rate change will depend upon the tax system in place, the time period being considered, the ease of movement into underground activities, the level of tax rates already in place, the prevalence of legal and accounting-driven tax loopholes, and the proclivities of the productive factors. If the existing tax rate is too high…then a tax-rate cut would result in increased tax revenues. The economic effect of the tax cut would outweigh the arithmetic effect of the tax cut.

However, returning to Piketty, this time in the 2011 paper, Optimal Taxation of Top Labor Incomes: A Tale of Three Elasticities by Piketty, Saez and Stefanie Stantcheva, the evidence underpinning this curve is again highly questionable. As they point out in the abstract (bold type added by me):

This paper presents a model of optimal labor income taxation where top incomes respond to marginal tax rates through three channels: (1) standard labor supply, (2) tax avoidance, (3) compensation bargaining…The macro-evidence from 18 OECD countries shows that there is a strong negative correlation between top tax rates and top 1% income shares since 1960, implying that the overall elasticity is large. However, top income share increases have not translated into higher economic growth. US CEO pay evidence shows that pay for luck is quantitatively more important when top tax rates are low. International CEO pay evidence shows that CEO pay is strongly negatively correlated with top tax rates even controlling for firm characteristics and performance, and this correlation is stronger in firms with poor governance. All those results suggest that bargaining effects play a role in the link between top incomes and top tax rates implying that optimal top tax rates could be higher than commonly assumed.

There are a number of charts which could be used from this paper, but I have chosen the plot of economic growth against changes in top marginal tax rate to illustrate most clearly the problems with the Laffer Curve idea:

This graph should show an inverse relationship if the Laffer Curve were true.

Why do I feel the need to debunk these simple so-called economic laws which are nothing of the sort? Because you will always prioritise economic growth over everything else if you believe that:

Growth will fix inequality;
Growth will fix pollution;
Trying to fix inequality through the tax system is counter-productive.

And these beliefs will then also have policy implications when faced with a different sort of curve.

This was an explainer from Grant Sanderson at 3Blue1Brown about COVID-19 from March 2020 setting out quite simply how it was likely to spread, and how different case numbers in different countries (eg between Italy and the UK) were as likely to be due to being at different time points since the start of the pandemic as reflecting the relative success of their containment policies. We now know the UK Government locked down too late, at least partly because they prioritised economic growth over containment policies in the first few weeks:

Those attitudes changed and we have had an incredibly successful vaccine rollout in the UK, but this has been at the expense of any idea of international cooperation in vaccine supply. Wealthy countries such as the UK have bought enough vaccinations to cover our populations almost three times over, while Covax, the global vaccine procurement scheme, only aims to vaccinate 20% of the populations of recipient countries this year.

This is very short-sighted if we think there might be an international issue even more threatening to life than COVID-19 which can only be combatted by unprecedented levels of international cooperation. And of course this is exactly what we have in the form of the climate emergency and our final graph (from the National Oceanic and Atmospheric Administration (NOAA) in the US showing the relentless rise in the level of carbon dioxide in the atmosphere as global emissions continue to increase:

Living in Hope-over-Experience may be very comfortable for some people for a limited time, but if it stops us engaging with the more implacable curves of the world we actually live in then none of us will be safe.

A success made of failures

It starts in 2025 with a description of a horrific heatwave in India which will stay with me for a very long time. As well it should as, in the book, it kills 20 million people. In response, India send thousands of aircraft up to 60,000 feet to spray aerosol particulates of sulphur dioxide into the stratosphere, in defiance of the international conventions banning such activities, to deflect some of the solar radiation with the aim of reducing the probability of future heatwaves for a period. By how much or for how long or with what other consequences is unknown.

As we build up to COP26 in Glasgow in November this year, in the book we start with the results of COP29 in Bogota, where the organisation which would come to be known as The Ministry for the Future (and the title of the book by Kim Stanley Robinson) was set up “to advocate for the world’s future generations of citizens, whose rights, as defined in the Universal Declaration of Human Rights, are as valid as our own. This new Subsidiary Body is furthermore charged with defending all living creatures present and future who cannot speak for themselves, by promoting their legal standing and physical protection.”

The Indian crisis happens a few months later. The new head of this body, Mary Murphy, is briefly held captive by, Frank, one of the survivors of the heatwave in her own flat in Zurich (the book also feels like a love letter to Zurich) and challenged to do more:

It’s not enough. Your efforts aren’t slowing the damage fast enough. They aren’t creating fixes fast enough. You can see that, because everyone can see it. Things don’t change, we’re still on track for a mass extinction event, we’re in the extinctions already. That’s what I mean by not enough. So why don’t you do something more?

This has a profound impact on Mary, who keeps in touch with Frank and his troubled suffering life throughout the book. It also leans her towards effectively endorsing the involvement of her No 2 in “black” operations to ensure certain people are “scared away from burning carbon”.

Indeed the book is suffused with eco-terrorism. Technological progress has partly displaced the state monopoly of violence, with drone technology in particular meaning that no aircraft or ship or surface navy is safe from a well-enough organised group by the end of the book. People stop flying when aircraft start being shot down regularly, and those that still do fly use carbon-negative airships, where solar panels generate more power than the ships use. Davos attendees get taken hostage and given a compulsory seminar at one point. Tax havens become obsolete when all money becomes digital and tracked.

Mary’s interactions with central bankers are probably the closest this book ever comes to comedy. In the first, she tries to argue for a “carbon coin”, a digital currency which would be paid out to organisations and people who could prove they had removed carbon from the environment. This would be the incentive to work alongside the carbon taxes. The contemptuous response from the Federal Reserve and others at first is “not our purview”, however by the end they are on board with this and many of the other ideas developed along the way.

There are so many ideas in this book, far too many to cover them all here: some of them familiar to me from economics (carbon quantitative easing, Jevons’ Paradox, Modern Monetary Theory, Gini Coefficient – these each get a short chapter among many other ideas and interspersed with riddles) and others not so. The Indian techno fix is the first of many: some successful, like sucking out the meltwater under glaciers to slow them sliding into the ocean and others not so, like the billionaire wanting to refreeze the oceans. Russia dyes parts of the Arctic yellow to reflect more sunlight back. Huge areas of land are rewilded.

What strikes me most is that the arguments we tend to have here and now about which course to take (Freud’s phrase is quoted here in the book – “the narcissism of small differences”) seem largely moot in this one imagined near-future: all of them are tried there – it’s not techno-fixes or de-carbonisation of transport and heating, it’s both. It’s not carbon QE or re-wilding, it’s both. If something doesn’t work, it’s abandoned. By far the most important determinant of which of the IPCC future scenarios we end up on seems to be how quickly we start. Economists come in for particular ridicule there – whatever course of action is planned, they can find one group who thinks it will have one effect, one who think it will have the opposite effect and one which thinks it will make no difference at all. The difference is that the economists are no longer guiding policy there, but facilitating and post hoc rationalising it.

There is a wartime feel to the book throughout, with people doing what they feel needs to be done in desperate circumstances. The choices are all different levels of bad, but bad is almost incalculably better than worst. And the overall impression is of a world changing rapidly, with one of its herd animals belatedly getting into better balance with the others. Even at 560 odd pages the impressions are inevitably just that – one chapter is just a list of different organisations working on aspects of the climate emergency in different countries, described as about 1% of the total number active. It is like the shards of a smashed wing mirror picking out details from the vanishing world behind. I have never wanted to apply the word polymesmeric (which I first saw on the cover of Catch 22 by Joseph Heller) to a book as much as I have to this one.

The hoped-for outcome of all of this? In one conversation this is described as a “success made of failures” or a “cobbling-together from less-than-satisfactory parts”, which I think sums it up nicely.

And I definitely want to visit Zurich one day. Probably by airship.

Getting Serious About Miracles

There are many papers about model risk, and the dangers of blindly relying on algorithms or metrics without allowing for human judgement at any point in any subsequent analysis (in effect “baking in” whatever analysis was done at the time the computer model or algorithm was constructed as the final word), but these can often descend into the same level of technical impenetrability as the programmes they are attempting to critique.

I watched the film Sully: Miracle on the Hudson for the first time this week, on the anniversary of the landing on the Hudson. In the final scenes there is a hearing (spoiler alert!), where the evidence presented up until that point based on computer simulations, with and without pilots involved, was leading to the unanimous conclusion that Sully and Skiles could have turned back to La Guardia or Teterboro airports rather than landing on the Hudson River in January. However Sully had appealed to have the video recordings of the pilot simulations shown to the hearing, and these revealed the pilots responding to the catastrophic bird strikes which had taken out both engines (again something later confirmed when the actual engines were recovered, but which the simulations themselves did not accept because of the instrument readings on one of the engines from the aircraft) by calmly immediately setting course for La Guardia or Teterboro with no decision or response or recovery time needed at all. When a 35 second allowance for this was inserted into the simulations, the results were fatal crashes in both cases.

What struck me was how invisible this deficiency in the programming of the simulation would have been without a cockpit recording of the simulations. In many of the programmes we use to automate judgement-heavy processes, such as recruitment, many of the capital allocation decisions in financial institutions or even A-level grades, we do not have anything equivalent to a cockpit recording available to us. Perhaps we wait until either events prove us wrong (bad) or those on the receiving end of our automated decisions start to complain in sufficient numbers for us to reconsider (worse). What if quite a large proportion of the cost savings from automating these processes is in fact illusory as a result of our not putting enough time and attention into the original programming and/or not setting aside enough budget for maintaining it and challenging its decisions with parallel processes which do allow for human judgement? How much bigger is this problem going to become in the era of machine learning, where the programmes we are running are themselves several steps of abstraction away from those originally written by humans?

Our ability to programme machines to carry out billions of calculations in seconds would have been regarded as miraculous only a few decades ago and is still pretty astonishing to us now. We need to start thinking a lot more about how we can live alongside these ever more capable machines amicably over the long term. And it can’t be only programmers who get to see what the machines are doing – whatever the technical problems of allowing the equivalent of a cockpit recording to be made which can be understood by any of us, they need to be solved with as much urgency as the process automation itself. All of our decision-making processes need to be understandable and challengeable by the society in whose name they are carried out. It’s time to get serious now about our miracles.

Let’s stop worrying about “damaging” GDP and transfer risks back to where they belong

“We won’t go back to normal, because ‘the normal’ was the problem.”

For me the turning point came on 12 March, when the FTSE 100 fell by 639 points or around 11% of its value in one day. What were the newspaper headlines that day?

Only the Times and the Financial Times had the stock market fall on their front page at all. Everyone else led with some variant on the Prime Minister saying that many families would lose loved ones. The attention switch was so complete that when KPMG published their UK Economic Outlook for March 2020 the following week – forecasting a main scenario for Gross Domestic Product (GDP) in the UK to fall by 2.6% in 2020 then grow by 1.7% in 2021, and a downside scenario for GDP to contract by 5.4% in 2020 and by another 1.4% in 2021, representing a slightly more severe recession than the downturn experienced in 2008-09 – nobody noticed that either (19 March and 20 March headlines here and here respectively), sandwiched as it was between the announcement that schools were to close and the Prime Minister saying that we had 12 weeks to turn the tide.

KPMG’s report was an example of damage function modelling of course: trying to model changes in economic activity due to some phenomenon and summarising that change in terms of a change in GDP. I have recently been quite exercised by similar considerations with regard to climate change damage functions and the inconsistencies of the ones in most current use with climate science. However it has become increasingly clear to me that I may have been missing the point. I realise I was focusing on damage functions because I felt they were leading to extreme optimism in the modelling of the impact of climate change on our economies and that it was this link which was most likely to get the attention of policymakers (and other actuaries!).

But of course GDP is only ever a proxy for some of the things we regard as important, rather than something that is important in itself, and a flawed one too. As Diane Coyle’s excellent book, GDP: A Brief But Affectionate History, makes clear. Its problems include:

It under-records growth by failing to capture fully the increase in the range of products in the economy;
It becomes a worse measure as the world economy consists less and less of material items, eg online activities; and
It can show positive growth caused by clearly unsustainable practices and those which deplete natural resources.

When KMPG released their economic outlook, it was as if they were trying to drag a weary world population away from the windows and balconies from which they are still trying to connect with each other and what is still real in the world back to the Monopoly game that they have set up in the front room.

It took a lot to get our behaviour to follow this change in attention. When Wuhan went into lockdown on 23 January, I was talking to Stuart McDonald, now a member of the COVID-19 Actuaries Response Group, about the talk he was planning to do at the University of Leicester on 18 March and deciding he would probably need to add a few slides about coronavirus. Italy went into lockdown on 9 March and yet on 12 March we had a second call where we still felt on balance that it might go ahead as long as we took sensible precautions, but by this time it was almost entirely about getting accurate messaging out about COVID-19. We called it off the following day. The UK finally went into lockdown on 23 March.

So perhaps it is no wonder that we have so far been unable to change human behaviour to anything like the same extent in response to climate change, which is a bit like COVID-19 in slow motion, progressing unseen with each stage of its development effectively locking us into the next steps in its relentless escalation. In the same way that movement restrictions may not slow down the increase in new cases for perhaps around a week, stopping carbon emissions now would still see us locked into further warming for 40 years. And even with the greater immediacy of coronavirus, it has only been when we have decided we care more about saving each other than maintaining our GDP that real progress has become possible.

My view is that some things that must be different post COVID are already clear. I think as a society we are going to demand more resilience, for example:

Resilience of our health service – this means much higher levels of spending, building deliberate over-capacity into the system in normal times;
Resilience of our food supplies, for example strengthening domestic supply chains;
Resilience of our population, so that we do not have 1.6 million food parcels needing to be given out in a year by the Trussell Trust, in the absence of a pandemic, for instance; and
Resilience of our infrastructure – to everything from floods to banking crises to pandemics to storms and heatwaves.

The Institute and Faculty of Actuaries (IFoA) has therefore shown great timing in its launch of its 2020 thought leadership campaign The Great Risk Transfer. The campaign aims to examine the trend of the transfer of risk from institutions to individuals, and how people can be better equipped to manage the financial risks they now face. I think the campaign rightly highlights the fact that risk transfer is all one way, but it clearly also goes way beyond the finance sector. Rail franchises never took on any real risk, it appears, even before the pandemic. Nor have PFI contracts, despite the price tag. By contrast the incremental removal of risk pooling by corporations for their employees and/or government for their citizens over the last 40 years has been relentless and in one direction only.

As Andrew Simms, one of the Green New Deal Group, said on Twitter yesterday about taking lessons for the climate emergency from the pandemic crisis:

Those roads with a fraction of the traffic, the drop in aviation, the economic shift to put public health & well-being first, the speed with which the brain adapts to the new normal: as someone said, these things are a postcard from the future we need to get to. Let’s take notes.

We Know Zero
