Do cuttlefish dream of the passive electroreception of sharks?

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.

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

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.

 

A-levels, algorithms and pulling up the ladder

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.

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.

Avoiding mean observances of paltry decorum

CPD doesn’t have to feel like this: a youthful man-o’-warsman, from the diary of an English lad who served in the British frigate Macedonian during her memorable action with the American frigate United States; who afterward deserted.

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!

Actuaries and the Event Horizon

Credit:ESO, ESA/Hubble, M. 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.

Actuaries and the Green New Deal

Images from the Birmingham Climate Strike on 20 September 2019

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.

Catch 22 and Actuarial Practice

Catch 22 can in no way be compared to actuarial practice. One puts its characters in impossible positions, with constantly shifting targets, rewards often inversely proportional to the social usefulness of the characters’ actions and against a backdrop inordinately preoccupied with death. The other has recently been on our TV screens directed by George Clooney.

The most recent link between the two was provided by John Taylor’s excellent Institute and Faculty of Actuaries (IFoA) presidential address last month. He encouraged us all to look at Jimmy Reid’s 1972 speech at Glasgow University (an extract showing the passion with which it was delivered can be seen here). So I did. John picked out the following passage:

I am convinced that the great mass of our people go through life without even a glimmer of what they could have contributed to their fellow human beings. This is a personal tragedy. It’s a social crime. The flowering of each individual’s personality and talents is the precondition for everyone’s development.

Inspiring as that is, my eye was drawn to a different passage of Jimmy Reid’s speech:

Society and its prevailing sense of values leads to another form of alienation. It alienates some from humanity. It partially dehumanises some people, makes them insensitive, ruthless in their handling of fellow human beings, self-centred and grasping. The irony is, they are often considered normal and well adjusted. It is my sincere contention that anyone who can be totally adjusted to our society is in greater need of psychiatric analysis and treatment than anyone else.

They remind me of the character in the novel, Catch 22, the father of Major Major. He was a farmer in the American Mid West. He hated suggestions for things like Medicare, social services, unemployment benefits or civil rights. He was, however, an enthusiast for the agricultural policies that paid farmers for not bringing their fields under cultivation. From the money he got for not growing alfalfa he bought more land in order not to grow alfalfa. He became rich. Pilgrims came from all over the state to sit at his feet and learn how to be a successful non-grower of alfalfa. His philosophy was simple. The poor didn’t work hard enough and so they were poor. He believed that the good Lord gave him two strong hands to grab as much as he could for himself. He is a comic figure. But think, have you not met his like here in Britain? Here in Scotland? I have.

This got me thinking about the investment requirements of the Green New Deal, as this would need to be a huge programme of work to transform our infrastructure and economy away from the carbon-burning planet-trashing Doomsday machine it currently is, which in turn would need huge levels of investment.

I have previously written about some of the views about how we might reduce our current reliance on carbon: the one with the most coherence in my view being the Green New Deal.

However there is a problem. Since our current system, the one which needs to be transformed, is currently predominantly doing the financial sector’s equivalent of rewarding people for not growing alfalfa (for example the misallocation costs estimated by SPERI at £2.7 trillion between 1995 and 2015 from having too large a financial sector here), any Green New Deal spending, at least to start with, is going to have to come from the Government.

The authors of the latest report from the New Economics Foundation anticipate that the massive increase in public spending required to make it happen would be between £20 billion and £40 billion a year. This level of public spending is inconsistent with our current ways of measuring fiscal space, or the room for additional Government spending. Government borrowing is normally expressed in terms of a percentage of GDP and has historically been around 1.3% pa in normal times (ie other than wartime or bailing out the banks). They therefore suggest:

  • The development of a new framework, defined in terms of the threshold beyond which there is a significant risk of adverse economic effects. This would have prevented the damaging austerity policies since 2010, for instance.
  • The parallel development of a tool which would allow policymakers to accurately assess the implications of holding back fiscal space compared with the implications of borrowing for investment, and therefore allow politicians to come to an informed view on the best combination of fiscal intervention or fiscal prudence at a given point in time, including with respect to climate related risks.
  • More explicit cooperation between the Bank of England and the Treasury, including the use of a new public investment bank (or network of banks) such as a green national investment bank (GNIB) – to increase commercial lending to green industries.

A particular interesting aspect of the GNIB is the proposal to make it independent of political interference. In the same way as those economists who argue for independent central banks so that governments don’t pursue damaging monetary policy in particular for electoral gain, some advocates of the GNIB believe it could be used as a backstop against governments underusing fiscal space for ideological reasons.

Richard Murphy points out that https://www.gov.uk/government/statistics/individual-savings-account-statistics shows £40 billion was saved in cash ISAs in 2017 / 18, and suggests that Green ISAs, backed by a Green Investment Bank and paying, say, 3% a year would be more attractive than current cash ISAs, therefore potentially meeting the GND funding requirements on their own.

Simon Wren Lewis, in his discussion of the many of the arguments around the Green New Deal and how it should be funded, makes the following excellent point (amongst many others):

No one in a 100 years time who suffers the catastrophic and (for them) irreversible impact of climate change is going to console themselves that at least they did not increase the national debt. Humanity will not come to an end if we double debt to GDP ratios, but it could come to an end if we fail to combat climate change.

The Catch 22 of the title originally described the catch which kept pilots flying highly dangerous missions in World War 2 – they could only get out of them by being certified insane, but the very fact of trying to get out of them showed that they were in fact sane and therefore they had to keep flying. If we want far fewer actuaries to be employed in not growing alfalfa in the future and far more working on making the finance structures of our economy work better, whether to support a Green New Deal or more generally, we first need to embrace the idea that our current economic priorities are indeed insane.

 

Whether or not there is a strike, USS’s future depends on trusting its members

On 23 March 2018, Universities UK (UUK), the universities’ employer body, issued an offer to the University and College Union (UCU) to end the Universities Superannuation Scheme (USS) pensions dispute. The UCU agreed to put it to their members and, on 13 April, announced that the proposals had been accepted by a margin of around 2 to 1. The main proposals, as summarised by Sally Hunt the UCU general secretary, revolved around the setting up of a Joint Expert Panel (JEP).

The JEP’s members were proposed by UUK and UCU – Ronnie Bowie, Sally Bridgeland and Chris Curry were proposed by UUK (two actuaries and the Director of the Pensions Policy Institute respectively). UCU proposed Saul Jacka (professor of statistics at the University of Warwick and a Turing fellow at the Alan Turing Institute), Deborah Mabbett  (professor of public policy at Birkbeck) and Catherine Donnelly (associate professor at Heriot-Watt University, where she heads up a unit focusing on pensions, investment and insurance research). The Chair is Joanne Segars, a well respected and very experienced former CEO of the Pensions and Lifetime Savings Association (PLSA) who had most recently been working with the Local Government Pension Scheme.

The Terms of Reference of the JEP were also published, which stated that the purpose of the panel was to:

  • make an assessment of the 2017 valuation;
  • focus in particular on reviewing the basis of the scheme valuation, assumptions and associated tests; and
  • agree key principles to underpin the future joint approach of UUK and UCU to the valuation of the USS fund.

They also stated that the panel would take into account:

  • the unique nature of the HE sector, intergenerational fairness and equality considerations;
  • the clear wish of staff to have a guaranteed pension comparable with current provision whilst meeting the affordability challenges for all parties; and
  • the current regulatory framework.

All of the bits relating to the 2017 valuation were reported on in September 2018, with recommendations from the JEP on ways of bringing the total contribution rate below 30% of pensionable pay.

In response to this, the USS Trustee made a proposal for concluding the 2017 valuation and preparing a 2018 valuation which could more fully take account of the JEP recommendations. This was accepted by UUK after a reduction in deficit reduction contributions from 6% to 5% was made and finally by the Pensions Regulator here, which noted that the proposal for the 2017 valuation is at the very limit of what TPR finds acceptable as it would see the Scheme carry higher levels of risk than we would consider manageable for a ‘tending to strong’ covenant.

The 2018 valuation process has been proceeding at pace, with the USS Trustee proposal following the consultation response from UUK of 3 options for future contribution patterns leading to indicative agreement from UUK for the third option of a total contribution rate of 30.7% from October 2019 and a further valuation in 2020. Following the September 2018 report, the JEP is working on a follow up report for September 2019 in relation to the USS valuation process in general. The second phase of work on the USS valuation has two parts; the first is concerned with the valuation process and governance, the second with the long-term sustainability of the scheme.

UCU have rejected all 3 options and set out a timetable for ballots on industrial action from 9 September in the event of any agreement which does not represent no detriment to members, ie no reduction in benefits or increase in employee contributions from the 8% level they were at before 1 April 2019. The JEP have suggested (while accepting that their numbers are indicative only, without detailed modelling) that, if all the measures they propose were adopted, the contribution rate could be reduced to 29.2%, split 20.1% employer and 9.1% employee in accordance with the cost sharing agreement. This compares with the USS Option 3 proposal of a split of 21.1% employer and 9.6% employee.

The UCU position looks a long way from the one that the Trustee and UUK appear to be edging towards, and I fear that a strike ballot may therefore be inevitable.

However, I think there is an equally important area mentioned in the JEP report where USS can radically improve how its members engage with a scheme which will be, for most, their major source of income in retirement.

How USS engages with its members

In their report the JEP, rightly I think, devoted several pages to member involvement in the valuation process, information and transparency and building trust and confidence, matters which will be a particular focus of their second report. They observed that:

  • longer consultation periods, initiated at an earlier stage, could facilitate member involvement via universities’ internal processes, which might help to build confidence in the valuation and a shared sense of ownership – helping to avoid future, damaging, industrial disputes.
  • there is no formal, scheme-wide mechanism for involving members in the valuation process or for assessing their appetite for changes to the Scheme
  • for future valuation cycles it will be important that the Trustee and Scheme Actuary interact more, at an earlier stage, with all stakeholders, particularly with regard to setting valuation assumptions and expectations
  • lack of understanding is likely to have contributed to falling levels of member confidence in the Scheme. It might be helpful for the Scheme to provide simple-to-understand guides which use clearly defined terminology to aid the understanding of the majority of Scheme members
  • the lack of trust in the valuation process and the Scheme has given rise to a view, albeit not a universal one, that USS is not being as open as it could be with stakeholders….whilst observing the need for confidentiality…the Panel suggests the Trustee may wish to consider how to share more of the information currently deemed confidential, eg on a redacted basis or in a summarised form. This would aid understanding of the valuation process…and, importantly, help rebuild confidence in the Scheme and its governance.

I would take such suggestions a step further, as I believe much of this communication would be wasted within the current adversarial environment, and indeed would be likely to be “spun” by one side or the other. It is clear that there is little trust in the USS Trustee on the part of the UCU officers. However, the ability of the 21,685 (out of 24,707 total votes) who voted to strike and then the 21,683 (out of 33,973 total votes) who voted to end the strike to determine what could or could not happen to a scheme with 396,278 members (as at  31 March 2017, 190,546 of them active) was, I think, unhelpful to the process of achieving a consensus more generally. Engagement needs to go much further than negotiations between UUK and UCU during valuation processes. USS does need to do far far more, in conjunction with the UCU and others, to engage members to help them understand their finances first before launching into what can be fairly abstract pensions discussions even for university professors.

The good news is that the membership have become much more aware of their pension scheme, mainly as a result of last year’s industrial action, and, being the inquisitive people they are, will I am sure now be looking for a higher degree of information (and education) from their pension provider about their benefit provision in future.

As the Pensions Policy Institute and many others have been saying for years, the decisions we are asking people to make are complex and subject to many different influences and biases. These decisions can be helped enormously if more care is taken in the nature and timing of how members are communicated with. Members will not value benefits they don’t understand and ultimately this scheme is only going to work in the long term if the people in it are trusted to be part of the decisions about its future.

Business macroeconomics for actuarial students – the first year

I have just finished teaching the Business Macroeconomics module on the BSc Mathematics and Actuarial Science programme at the University of Leicester for the first time, as part of our response to the Institute and Faculty of Actuaries’ (IFoA) Curriculum 2019 exercise, which has refreshed and in many cases entirely revamped what is expected to be learnt by actuarial students.

Actuarial students are not expected to be experts in economics, but they do need to know enough to be able to ask sensible questions and also to be aware of what is available to them from economics when tackling business problems. One stimulus for the revamp of the Business Economics subject by the IFoA was the general feeling that actuaries had, in some cases, been drawing on a narrower range of economic thought than needed to fully address all dimensions of the increasingly complex and multidisciplinary problems we face as a profession.

One of my key references when structuring the course (while not wanting to depart too far from Sloman, the source of most of the syllabus, in my first year of teaching it) was The Econocracy: The Perils of Leaving Economics to the Experts, by Joe Earle, Cahal Moran and Zach Ward-Perkins. As graduates from economics degrees themselves, they make a very convincing case for how economics as it is taught at university has little to do with the real world, often uncritically setting out a model based on rational individuals and an economic system that tends towards equilibrium. They advocate amongst other things the teaching of different schools of economics and also a greater focus on economic history. As the new IFoA syllabus had specifically added these last two points as part of the review, I felt encouraged that this was also criticism shared by the actuarial profession. Indeed, the Actuarial Research Centre of the IFoA have recently engaged Dr Iain Clacher on a project to understand how economics interacts with the actuarial profession, with the following initial conclusions:

  • The current regulatory environment may be counter-productive in some cases, particularly if it is based on too narrow an economics focus.
  • The much more quantitative approach to economics which has been dominant for the last 60 years or so may be pushing us towards a world where we think less.
  • There is scope for the actuarial profession to take much more from economics in trying to understand what is really going on.

One quote from The Econocracy which particularly struck me was:

It is hardly an exaggeration to say that it is now possible to go through an economics degree without once having to venture an opinion.

One of my objectives in teaching this module was therefore to change that, and to try and focus as much as possible on giving students the opportunity to develop opinions as they grapple with trying to understand what is really going on.

Have I succeeded? Well while it would not be true to say that I have been entirely successful, neither would it be accurate to say that I have not succeeded at all. I changed the examination from one where 80% of the marks were for multiple choice questions to one where only 16% were, with 60% devoted to four long questions requiring, at least in part, higher order skills of analysis and the ability to make an argument. The examination was 70% of the overall module mark, with 30% for a 3,000 word mini project which investigated whether the Office for National Statistics were correct in their proposal to re-designate student loans within the national accounts and asking students to comment with reasons on whether they agreed with the approach taken for valuing student loans for sale. And I broadened out the references within the course significantly, for example:

Amongst many many others.

Students found it tough at times, as some of the feedback I received made clear. Much of macroeconomics can be counter-intuitive, particularly for first year undergraduates. But those who engaged with the module definitely ventured opinions along the way! There was a lot of reading required, for much of which I provided more concise lecture notes, but there is plenty of scope for being more targeted next year in what we dig into in more detail. There will be less on the schools of thought at the beginning next time, as in my view it makes much more sense drawing this out as particular aspects of economic theory are being discussed – much better I think to work on the students’ comfort in group working initially, so as to get them discussing the subject more openly earlier. I also did not use the material built around the Core Project’s The Economy as much as I would have liked this time, although it was available to the students. I will be discussing how I can remedy this at the RES Nuffield Foundation Workshop: Teaching and Learning with CORE at the University of Warwick this week!

It has been a very stimulating experience and greatly increased my understanding of how actuaries have traditionally approached economics questions, while also allowing me to explore ways in which I would want those approaches to change. I look forward to Year Two!
