I was looking through my old blog posts the other day and came across something I wasn’t looking for. Actuaries and Science Fiction told the story of a one-off visit I made to the Birmingham Science Fiction Group (BSFG), when the guest speaker had been the late great Brian Aldiss, who told the story of a time Kingsley Amis had had dinner with Margaret Thatcher. He told her what his book Russian Hide and Seek was about, to which she had responded that he needed to get himself another crystal ball.

By coincidence, I have just joined the BSFG nearly 10 years later (well I needed to think about it!), attending my first meeting online (Anna Stephens – really good about writing for Warhammer and Marvel in particular) and now very much looking forward to seeing Alastair Reynolds at my first in person meeting next month. I now have a bit more context for the Kingsley Amis story, as Andy Beckett has an account of a dinner Amis had at Thatcher’s Flood Street house in the late 70s (before she became Prime Minister). He wrote at the time:

I was rather overcome with the occasion and the fairly close propinquity of Mrs T…very much a new face to me as to most people, too much so to take in a lot about the fare except that it was properly unimaginative, and, as regards drink, ample enough. The hostess wore one of those outfits that seem to have more detail in them than is common, with, I particularly remember, finely embroidered gold-and-scarlet collar and cuffs to her blouse…[she was] one of the best-looking women I had ever met and for her age…remarkable.

And he also attributed the following quote to Thatcher herself:

People have always said that the next election is going to be crucial. But this one really will be, and if it doesn’t go the way Denis and I want then we’ll stay [in Britain], because we’ll always stay, but we’ll work very hard with the children to set them up with careers in Canada.

Anyway, back to Aldiss. He had told the story as he felt it showed how Thatcher (and he was not just picking on her as he felt this was a view held by many) misunderstood science fiction. It was not about prediction of the future, but for people who “liked the disorientation” of portraying an unfamiliar landscape.

Ursula K. Le Guin goes further in her introduction to The Left Hand of Darkness (just finished it and, if by any chance you haven’t read it already, it is an amazing piece of immersive world building which will leave you never feeling the same way about gender again). As she says:

Science fiction is not predictive; it is descriptive.

Predictions are offered by prophets (free of charge), by clairvoyants (who usually charge a fee, and are therefore more honoured in their day than prophets, and by futurologists (salaried). Prediction is the business of prophets, clairvoyants and futurologists. It is not the business of novelists. A novelist’s business is lying.

The weather bureau will tell you what next Tuesday will be like, and the Rand Corporation will tell you what the twenty-first century will be like. I don’t recommend that you turn to the writers of fiction for such information. It’s none of their business…All they can tell you is what they have seen and heard, in their time in this world, a third of it spent in sleep and dreaming, another third of it spent telling lies.

And, my favourite bit:

In reading a novel, any novel, we have to know perfectly well that the whole thing is nonsense, and then, while reading, believe every word of it. Finally, when we’re done with it, we may find – if it’s a good novel – that we’re a bit different from what we were before we read it, that we have changed a little, as if by having met a new face, crossed a street we never crossed before. But it’s very hard to say just what we learned, how we were changed.

The artist deals with what cannot be said in words.

The artist whose medium is fiction does this in words. The novelist says in words what cannot be said in words.

Who wouldn’t want to do that? It struck me while I was reading those words how the pandemic was something which changed all us survivors a little (and some a lot of course) and in ways that are often hard to put in words. But we are changed and there is work to do to try and understand how, even if that cannot be completely put in words.

The other thing from the introduction which has stayed with me is Le Guin’s contention that, while we read a novel, we are bonkers: believing in people who have never existed, hearing voices, perhaps even becoming other people. As she says:

Sanity returns (in most cases) when the book is closed.

But what about when you can’t close the book? Are we, to a greater extent, condemned to some level of future insanity? As William Faulkner said:

The past is never dead. It’s not even past.

In 2013 I tried to suggest that actuaries might also be about portraying an unfamiliar landscape and trying to work out what would hold true under different circumstances, and that they should therefore put themselves about a bit more, even if they sometimes made themselves look a bit foolish in the process. As William Hynes reminded me at yesterday’s excellent An introduction to alternative economic thinking event (recording available soon from the Institute and Faculty of Actuaries), the group of economists responding to the Queen’s question as to why noone saw the 2008 crisis coming, concluded:

In summary, Your Majesty, the failure to foresee the timing, extent and severity of the crisis and to head it off, while it had many causes, was principally a failure of the collective imagination of many bright people, both in this country and internationally, to understand the risks to the system as a whole.

If a failure of imagination is the main problem, I would suggest that science fiction must be at least a part of the solution. Looking a bit foolish at times is a bit of a speciality for me, so you probably won’t be surprised to hear that I am devoting most of my time from here on in to an almost certainly doomed attempt to write what Le Guin might regard as a good novel. I have been here before, way back in my pre-actuarial past, and have a nice back catalogue of unpublishable books and rejection letters to look at whenever I forget that I have no idea what I am doing. But if I find myself shouting to noone in particular that what I am trying to say cannot be said in words, I might dare to believe that I am on the right track.

Hundreds of thousands of public sector workers were on strike today. I was one of them. Meanwhile the Bill above is making its way through Parliament – it was voted through earlier this week by all but one of the Conservative MPs, but is currently getting rather more scrutiny and push back in the House of Lords.

It seems likely that there will be legal challenges to some elements of the Bill and that some of them will be successful. The Labour Party have promised to reverse it if they win the next election.

I spent my first strike day ever (yes, I know, I am just a political union member and a mere picket tourist – all of these criticisms are entirely justified) by attending a meeting of the Leicester Actuarial Science Society with the Institute and Faculty of Actuaries (IFoA) President Matt Saker. It was a very well attended event and there were a lot of questions for Matt. These ranged from the IFoA strategy in Africa, to mutual recognition agreements with the Institute of Actuaries in India to the pros and cons of the recent vote to create a Chartered Actuary status for associates and fellows to the future relationship of the profession to AI applications, reflecting the global nature and broad range of interests of the student audience. I felt very much like I was witnessing the next generation of actuaries getting stuck into the issues that would be important to them through their careers, and it was inspiring to see.

Back to the strike. I differ from many of the strikers interviewed in that, in my view, I was not doing anything particularly altruistic by striking. I was standing up for my own pay and conditions. Which, it seems to me, everyone should be able to do in a free society. Years of anti union legislation, uberization and the growth of sectors with weak unions has made us used to having to negotiate for ourselves individually or in small groups against much more powerful employers. The fall in real pay over the last 12 years indicate that this has not really worked for us and perhaps a new era of collective bargaining is now necessary.

Meanwhile the Government thinks that it is a better idea to muzzle unions and repress future strike action than to deal with any of the grievances of the workers they represent. They think this is a better idea than to build anything, invest in anything, or do anything positive at all. You have to ask who such a move, temporary and largely struck down as illegal as it is likely to be, is designed to impress: future party donors perhaps?

The next generation I saw today did not strike me as one which will have much patience for such manufactured class wars and the governments which manufacture them.

It is my hope and, after today, my belief that they will think we have more important things to be doing.

I originally talked about Chartered Actuary status (here, with the cartoon above) when the Institute and Faculty of Actuaries (IFoA) first proposed the idea and set up a consultation in 2018. I said then that sometimes an idea comes along that seems so obviously good that you wonder why it hasn’t been done a long time ago.

Four years on from the retreat from the proposal following the slenderest of straw polls offering some challenge, and it remains a good idea. There are still relatively few full actuarial roles available for associates and many firms still assuming a default career path of continuing to fellowship.

There are some differences this time however:

  • There will be two chartered actuary designations: Chartered Actuary (Fellow) and Chartered Actuary (Associate), with the hope that the FIAs who were most concerned with maintaining their distance from AIAs last time will now support the proposal. The original proposal suggested Chartered Actuary (CAct) would be a single distinct qualification, a required qualification point for all student actuaries to reach before going any further and globally recognised as the generalist actuarial qualification from the IFoA. This approach has been abandoned, with no requirement to complete the core curriculum before tackling specialist modules. It will be interesting to see whether Chartered Actuary (Associate) will be seen as a destination in its own right, or just a change of letters. This will depend on all of us within the profession (see below).
  • The environment we are operating in has certainly changed, with the replacement of our regulator, the FRC, by the Audit, Reporting and Governance Authority (ARGA). One of the concerns that the IFoA were looking to address in 2018 was that another, much larger, profession, could pose an existential threat. If actuaries have a unique skill set, which is likely to be lost to a wide range of businesses and other sectors if it is unable to meet the demand for those skills due to a simple lack of numbers, then the need to take any perceived barrier to practise away from our emerging young professionals is clear. The move from FRC to ARGA does not remove this threat and there also remains in the regulatory proposals to date the threat of differential regulation, where actuaries are regulated more heavily than other professionals doing similar work could price us out of markets where we have value to add. The profession therefore needs to grow to increase our voice and influence over the future regulation of the profession.
  • We have acknowledged the impact of the Great Risk Transfer within the finance sector, but in my view the impacts more generally of the increased individual risks and uncertainties millions of the UK population face as energy, food and housing costs escalate need to be faced up to by our profession. For that we need to continue to be a destination of choice for a growing number of your people with a widening range of backgrounds and experiences.

So what do we need to do to make this a change worth making? We need to start behaving like a generalist actuarial qualification is what we want, and offering roles for actuaries on completion of core practice modules in future. It will mean not necessarily insisting on further actuarial specialisation as a requirement for senior roles within our firms. It will mean getting comfortable with a much wider range of specialisms amongst those we consider to be actuaries. Some are already doing this, but most of us need to go much further. A good place to start might be the IFoA’s own website, where the Route to Becoming An Actuary still features a diagram where an IFoA Associate is shown as a milestone on the way to the final destination of becoming a Fellow.

We do it all the time. We assume that the animals around us experience the world as we do, with our obsession with the visual sense. We are used to anthropomorphising animals in our cartoons, but it goes much further than that: for instance if, like a dog, your sensory world or Umwelt is primarily based on smell rather than sight, then that daily walk you take with your dog has very different highlights and notable features (amazingly the slits on the side of a dog’s nostrils allow it to smell on out-breaths as well as in-breaths). We have sayings based on these anthropomorphisms: for example, the “unconcerned” frog in the water as it is heated to boiling (cited by Emily Maitlis in her recent speech in Edinburgh) may not be unconcerned at all, merely showing its distress by filling the air with smells like peanut butter, cashew nuts or curry rather than via the reactions we would expect from a human.

Our vision is not even all that extraordinary compared to some other animals. Mantis shrimps have more classes of photoreceptors covering the ultraviolet spectrum than we have in total. They are the only animals who can detect circular polarization, where the plane in which the light is polarized also rotates. However they are much worse than us at telling our visual range of colours apart and may not even have a conception of colour as we know it at all. We don’t know.

We are not even sure how many senses there are. Aristotle said there were five (sight, hearing, smell, taste and touch), but missed our senses of proprioception (ie awareness of your own body) and equilibrioception (ie sense of balance). There are also animals who have a secondary system for detecting odours, or who detect the body heat of their prey via their brain’s visual centre or have sensors which both detect electric fields and pressure. How should we categorise these and does a clear division between senses make any sense? We don’t know.

Elephants can hear each other several miles apart just after sunset, but we don’t know what they are listening for. Beaked whales have a range of crests, ridges and bumps on their skulls which are not outwardly visible other than via the echolocation they use, but we don’t know why.

And finally, for now, the cuttlefish of the title. When cuttlefish sense sharks, who have passive electroreception (ie the ability to detect electric fields in other animals), they stop moving, hold their breath and cover their gill cavities to reduce the voltage of their electric fields by up to 90%. I could go on, but all of this and so much more is contained in Ed Yong’s masterful An Immense World, which I could not recommend more highly, not only for the content but also for the wonderful joyful writing throughout (AC/DC’s Rock and Roll Ain’t Noise Pollution even gets a mention!).

The recurring theme for me is how much we still don’t know about all of these animals, and the amazing new discoveries which are being made every year. Every animal perceives a different world from the one we think we are living in, many of these perceptions currently (and in some cases perhaps permanently) impossible for us to understand. It takes an extraordinary level of anthropomorphic arrogance for us to convert all of those strange and wonderful lives into the concept of natural capital.

The Institute and Faculty of Actuaries’ Biodiversity and Natural Capital Working Party defined natural capital in their paper from April 2021 (which acknowledges the concerns I am raising here and those raised by others) as follows:

The concept of ‘natural capital’ therefore aims to recognise nature as an asset and aims to ensure that
the goods and services offered by nature become a part of decision making by governments,
businesses, and individuals regarding resource allocation, growth and development.

The Dasgupta Review has gone further, focusing on the economics of diversity. As it acknowledges:

The Review has developed the economics of biodiversity by viewing Nature in anthropocentric
terms. That is an altogether narrow viewpoint, but it has a justification. If, as we have shown in
Part I, Nature should be protected and promoted even when valued solely for its uses to us, we
would have even stronger reasons to protect and promote it if we were to acknowledge that it
has intrinsic value.

I strongly disagree. As George Monbiot pointed out several years ago, markets change the meaning of the things we discuss, replacing moral obligations with commercial relationships. The latest article in The Actuary magazine on natural capital discusses ecosystem collapse in its final paragraph in terms of how it would “negatively impact GDP” and “economic value”.

Once the diversity of nature can be reduced to a monetary amount or metric value, it can obviously be modelled much more easily but, as we have seen again and again within the finance sector and elsewhere, that is at the expense of consideration of any other aspect of our relationship with it.

Perhaps cuttlefish do dream of the passive electroreception of sharks. If they only knew what we were up to, they might instead have nightmares about their balance sheet entries in our spreadsheets.

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.

 

I have written about school qualifications once before here in 2014, when I was criticising the move to adding an A* grade at GCSE and the consequent narrowing of the grade boundaries to mimic the A-level ones. We have of course since moved to a numerical grade system for GCSEs which is even narrower. However, if the exam grade system was a bad way to assess students, the algorithm which replaced it in the summer (explained here and critiqued here) was clearly worse still.

So, against a background of steadily less reliable grade information at both GCSE and A-level, it was interesting to look at the Institute and Faculty of Actuaries’ (IFoA’s) employer directory and note that, of the 25 separate adverts for graduate roles, 11 of them have an A-level or UCAS points requirement in addition to the university degree requirement. My question is why?

I understand that employers, particularly this year, are likely to have very large numbers of applicants and need some way of reducing the number they need to review in detail, but there are many much better sieves than A-levels these days. Psychometric tests can assess how rusty students’ numeracy is. Application forms can be digital and given a computerised first pass on any number of criteria and, if the questions are constructed thoughtfully, will give companies a smaller set of applicants much more closely aligned to their goals than the grade given at mathematics A-level.

Even if you accept the grades as representative, there are clearly issues around social mobility and widening participation from relying on them to exclude a large number of candidates initially, which was highlighted when an algorithm attempted to reproduce the results based on subject studied and school attended. The news today that they will not be trying this again this summer is encouraging, but even if mark allocations are fairer, many problems with A-levels remain.

I have felt that this has been a growing issue for some time – it has always seemed to me ridiculous that a student on my programme (the BSc Mathematics and Actuarial Science at the University of Leicester – a qualification accredited by the IFoA), doing well and on track for all 6 of the core principles exemptions available as a result, still feels the need to retake an A level taken before they had discovered the motivation for actuarial work that they now have, in order to have a chance with many of the top employers. Are those employers so lacking in confidence in the integrity of their own profession’s qualification system that they need the security backstop of an A-level pass?

It is likely to be a tough environment for young people attempting to start their careers this year, whatever their skill set. I hope employers will review their current approach to recruitment and check they are not inadvertently pulling up the ladder before seeing all of the talent available.

“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.

According to Daniel and Richard Susskind’s the Future of the Professions, there is a Grand Bargain between society and the professions, which means (and I am paraphrasing a little here), in return for professions providing:

  • Expertise, experience and judgement;
  • Delivered affordably, accessibly, reassuringly and reliably;
  • With knowledge and methods maintained and kept up to date, members trained, standards and quality of work enforced and only appropriately qualified individuals allowed in;
  • Acting honestly and in good faith; and
  • Putting clients interests ahead of their own.

Society will give the professions:

  • Respect and status;
  • Exclusive rights to perform/provide socially significant activities or services; and
  • Independence to decide how they do it and how much they can be paid for it.

It is with regard to the knowledge and methods point above that nearly all professions have some sort of continuing professional development (CPD) requirement. The Institute and Faculty of Actuaries (IFoA) consultation on their proposed new CPD scheme is currently open and runs until 17 April. I will be responding to it via the online questionnaire, but thought it might be worth airing a few points more widely too, to promote some discussion just in case anyone has any bandwidth for anything not directly corona-related at the moment.

Overall I think this is a move very definitely in the right direction. I have some criticisms, which I will come to, but I very much welcome:

  • the broadening of the scope of CPD activities. I am clearly not the only one who has experienced a talk or discussion or even an arts event about which I would have said, in the words of Walter Scott: One hour of life, crowded to the full with glorious action, and filled with noble risks, is worth whole years of those mean observances of paltry decorum, in which men steal through existence, like sluggish waters through a marsh, without either honour or observation. And yet would have been unable to record it in my CPD because there was no other actuary present and no way of proving I was there!
  • the introduction of reflective practice discussions. There are few details about how these will work and who will run them (the suggestion I took from the consultation was that they would be centrally run, which I think would be a mistake for reasons I will explain below). However in principle this is a great idea, getting people together to talk about what they are doing to develop their thinking in important areas and sharing their experiences on how the journey is going. I am not aware of any other profession moving in this direction currently, but I very much welcome it.
  • The removal of the need to be audited annually on CPD recorded. The 2018 Annual Report of the Disciplinary Board of the Institute and Faculty of Actuaries indicates that there were 2 cases of non-compliance with CPD referred to them and 3 cases of failure to hold a practising certificate. The current system therefore does bring the words sledgehammer and nut to mind.

However I do also have some criticisms:

  • there is much made of how they are proposing to prescribe a single requirement for all members. I found it difficult to answer whether I agreed or disagreed with this proposal as I didn’t feel that they had: people who work for firms who have signed up to the profession’s Quality Assurance Scheme (QAS), practising certificate holders, Practising Members (we will come to these), Non-Practising Members and students all have different rules applying to them. My concern here is that this 5 tier system will translate into inequalities of status within the profession, and some members having a louder voice than others.
  • keeping students (completely outside the CPD system via the Personal and Professional Development (PPD) scheme) and QAS members completely dependent upon their firms for professional development risks, in my view, narrowing the development undertaken rather than the broadening that the proposals overall intend.
  • I am very concerned about the examples given to clarify what is meant by a Non-Practising Member: retired from actuarial practice; not carrying out technical actuarial work; or on a career break. As technical actuarial work is not defined in the consultation, the suspicion is that this will be the usual suspects of life, general insurance, finance and investment and pensions, with wider fields including the education field where I practise, certainly NED roles but also perhaps resources and environment work or, particularly topical at the moment, health and care. Obviously members may choose not to apply for non-practising status, but I do not believe that they should have the option to if they are using their judgement to analyse complex situations to help the people or organisations they are working with to make decisions.
  • currently most categories of member need to complete 2 hours annually of Professional Skills Training (PST). The materials provided by the profession to support members in complying with this requirement are extensive and excellent, but there are a wide range of ways in which it is currently met, from company events to regional community events to individuals registering the video and other content they have interacted with online. In my view this allows members to tailor what they think they need in a given year and, as a provider of these sessions for a number of years now, I have been impressed by the open and frank discussions which have become possible with our attendees on difficult questions involving potential reputational risk. My main concern with the proposals on this are that members will not feel the need to subject themselves to these sessions if the professional skills requirements are to be relaxed as far as just a learning outcome related to managing professional ethical challenges.
  • I am enthusiastic about the replacement of the audit of CPD records with an invitation to a reflective practice session instead, however I would be concerned if these were all centrally controlled, as opposed to the wide range of current providers for PST. I well remember sitting in professionalism CPD sessions run by senior members of the IFoA in a room full of other scheme actuaries and none of us prepared to admit to making any mistakes in our client work in front of each other. It would be regrettable if these sessions became formalised to the point that they were no longer useful.
  • my final point is that, if we are moving from a strictly audited system to one which will be much more light touch, perhaps this is also an opportunity to increase the hours from the current 30 hours for practising certificate holders and 15 for nearly everyone else. Doing a quick check I found that the Society of Actuaries requires 50 hours over 2 years; and the General Medical Council requires 250 hours over 5 years. At the other end of the scale, the Institute of Chartered Accounts in England and Wales (ICAEW) and the Law Society have no specific requirements at all. The ICAEW, hilariously in my view, includes the following in its guidance: There is no requirement to achieve a certain number of hours or points, and the notion of structured and unstructured activities no longer exists. There is no requirement to attend a certain number of courses or seminars. There may be periods when, having reflected, you quite reasonably conclude that you already have all the current skills and knowledge necessary for your work and that you do not need to undertake any further CPD activity at that moment. However, if we believe, as I do, that our work has never been so technical nor demanded a wider range of skills, many of which have not been traditionally demanded of actuaries previously, we should surely require that we move closer to the top of this range.

CPD has a range of uses beyond meeting the Susskind’s grand bargain:

  • it allows us to share our practice with each other and challenge each other;
  • it allows us to move between practice areas or respond to new ideas in our existing ones;
  • it is a means for the profession to disseminate urgent changes in expectations of members (in conjunction with the alerts which are issued occasionally);
  • but, perhaps most importantly, it allows us as individuals to reflect on what we are doing and the direction we are taking and consider whether we might want to change either of these.

Carefully chosen, it really can spare us a system of Scott’s mean observances of paltry decorum and instead provide more hours of glorious action!

Kornmesser Information extracted from IPTC Photo Metadata: This artist’s impression depicts a Sun-like star close to a rapidly spinning supermassive black hole, with a mass of about 100 million times the mass of the Sun, in the centre of a distant galaxy. Its large mass bends the light from stars and gas behind it. Despite being much more massive than the star, the supermassive black hole has an event horizon which is only 200 times larger than the size of the star. Its fast rotation has changed its shape into an oblate sphere. The gravitational pull of the supermassive black hole rips the the star apart in a tidal disruption event. In the process, the star was “spaghettified” and shocks in the colliding debris as well as heat generated in accretion led to a burst of light.

We all know the concept of an event horizon. It is the point where you move past a point of no return without realising it, as David Finkelstein theorised in 1958 would happen as you approached a black hole. Steve Keen has set out why we may have done precisely the same thing with the climate here. The language is a little fruity in places (but justifiably so, in my view, to differentiate between serious economic research and the rubbish which Nordhaus and others have polluted the field of the economics of climate change with, the first 25 minutes gives you the general idea).

What should actuaries do in an event horizon situation? Well in some ways it depends on the political climate you are working in. Can anyone imagine an equivalent of Donald Trump saying that he didn’t believe in black holes and that spaghettification was invented by Italy to support their pasta industry? This probably doesn’t seem as ridiculous as it would have done only a few years ago, which demonstrates how the political environment has changed.

What actuaries have to do in an event horizon situation, in my view, is not to give up. That means:

  • pushing clients hard towards decarbonisation as quickly as possible; and
  • offering people investment opportunities which are part of the solution rather than the problem (the FT has pointed out that there is a proliferation of green funds, however Richard Murphy (one of the Green New Deal group) and others have pointed out that there is no way currently of knowing which if these funds are truly green – actuaries could play a leading role in accrediting funds to help with this.

Steve Keen is very pessimistic about the possibilities of a Green New Deal to meet the need to keep warming below 2 degrees above pre-industrial levels. And there are many that believe that you cannot decouple economic growth from carbon emissions. But they may be wrong, and in my view it is worth pursuing the restructuring of our economy which would be required to deliver it, if only to reduce the level of carbon rationing that will be required otherwise within our lifetimes. We do not have a Government which is remotely interested in this in power at the moment, so following this path comes with considerable professional risks, particularly when short term knee jerk policies to deal with currently failing companies (eg FlyBe) are going to be dominating the headlines, with even more to follow once the long-term realities of Brexit become apparent after 31 January. Another event horizon it would seem.

On the day millions have taken to the streets across the globe to demand a more urgent response to the climate emergency, it seems a good time to write about the crossbench Decarbonisation and Economic Strategy Bill, originally tabled by Caroline Lucas and Clive Lewis in March this year, which has now been formally launched. This “Green New Deal Bill”, as it has been dubbed, sets out a legislative framework for the changes that are needed to make the Green New Deal (a programme of action neatly summarised in the Green New Deal Group’s fifth report here) a reality. The impacts of these proposals would be far-reaching and radical, changing the way our economy operates and what we value. As well as revolutionising the way we live, this would also significantly affect the current work of actuaries and provide many opportunities for people with the actuarial skill set to be centrally involved.

The main proposals which I think would impact actuaries are as follows:

  • Bring offshore capital back onshore to make sure that government, not markets, can make the big economic decisions. This would obviously impact all businesses operating in financial markets. There would also be large movements in the value of some businesses as a result of economic decisions which have previously been left to the market now being made by government. Modelling the impacts of such changes and helping businesses manage the transition are examples of where actuaries can add value here. We are already seeing increasing disinvestments from coal, but this would seem to be just the start of a much wider realignment (one possible view of the potential is discussed here).
  • Greater coordination between the Bank of England, the Treasury and the Debt Management Office. This means the end of the independence of the Bank of England by the look of it, with monetary policy and fiscal policy run in much closer cooperation with each other. It also means more regulation for banks and the supported emergence of local banks and a new national investment bank.
  • New bonds, nationally and locally, and new pension arrangements targeted at the green renewal of our infrastructure. For instance, tax rules on pension schemes could be changed to require a minimum percentage of assets invested in such bonds in order to continue to qualify for tax relief.
  • New objectives for business, and new kinds of businesses. For instance, the UK-based Corporate Accountability Network argues that the whole focus of corporate reporting will have to change, and so too then would corporate behaviour because there is very strong evidence that what is reported by any organisation is what becomes important to it. The Green New Deal Bill provides for changes to both company law and accounting to embrace the need for legally required and enforceable reporting on progress towards any company becoming carbon neutral. This will certainly lead to new business structures as a result and, I would imagine, many new business opportunities for those with actuarial skills as a result.
  • Replacing our measures of progress. This is something I have long supported. The main problem is that there are many possible candidates for this, but that also means that there is a great opportunity for actuaries to be involved in constructing appropriate indices which are globally respected, thereby helping to change what we value away from our current GDP and FTSE fixations.

Of course there are also opportunities for those with actuarial skills to block the transition to an economy that isn’t constructed in such a way as to make environmental destruction inevitable. Employers like these would probably make those with the actuarial skillset very lucrative offers to use their skills. I hope that most of us, and particularly those just at the start of their careers, will resist such offers. We now know that tobacco firms hid the evidence of the damage done by their products for decades and firms such as Exxon have done the same in denying the science on climate change for over 40 years. Please don’t be part of the problem when you could be such a valuable part of the solution.

At Leicester, we intend to launch a new module on our MSc Actuarial Science with Data Analytics programme next year, specifically on the ideas behind the Green New Deal and focusing on the areas where ideas still need to be developed (one of the most exciting things about the Green New Deal is that it is still an area of live discussion, with many of the policy details still being developed). I would welcome any input from members of the Green New Deal Group or those with research interests in this area who would be interested in helping us develop the detailed curriculum of this module before launch.

This is an exciting time for those who are comfortable working with data and communicating what they have found in it. Let’s make sure that those skills are applied to the needs of 99% of the global community.
