Climate Change – Page 3

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

26. April 2021 · Write a comment · Categories: Climate Change, COVID-19, Economics, Prediction, Risk

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

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

The Kuznets Curve

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

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

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

Their data suggests a curve which looks like this instead:

The Environmental Kuznets Curve

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

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

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

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

The Laffer Curve

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

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

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

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

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

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

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

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

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

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

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

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

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

Now and Venn

Diagram 1

We are currently behaving like this is the world we live in – because if you are a finance person it is. The Dasgupta Report on the Economics of Biodiversity does nothing substantive to challenge this, despite a foreword from David Attenborough admitting “We are totally dependent upon the natural world”, other than putting a bigger number on the Sustainability portion (Natural Capital). John Kay mentioned in his talk, as part of the Dr Patrick Poon Presidential Speaker series on Finance in the Public Interest for the Institute and Faculty of Actuaries, the habit of actuaries in particular of often “attaching meaningless numbers to data”. There would seem to be great potential for doing precisely this in putting a number on Natural Capital.

But it is worse than that. As the September 2020 InfluenceMap report on sustainability finance policy engagement makes clear, most financial institutions (bottom-right quadrant, in blue, below) have shown caution and, despite having made some high-level supportive comments, have tended not to engage in a detailed or intensive manner. A small number of financial institutions (top-right quadrant, blue) have been actively engaged in promoting sustainable finance policy. A few financial institutions (centre-left of the diagram, blue) appear to be more cautious about sustainable finance policy.

This chart plots the results of InfluenceMap’s analysis for the financial institutions and industry associations included in the analysis. Engagement Intensity refers to how actively the entity is engaging, while Organization Score measures the degree of support/opposition to policy.

Diagram 2

In the meantime, the IFRS Foundation is proposing to set up a Sustainability Standards Board with its own reporting standards. This is what Richard Murphy (who got me thinking about this in Venn diagram terms originally) is rightly complaining about as it would lead to this:

His sustainability cost accounting idea offers a plausible alternative approach in my view. As the introduction says:

…accounting has to change because we need a clear, audited, enforced and unambiguous indicator of the process of change that business must go through to support continued human life on this planet. Sustainable cost accounting can do that by indicating who can, and cannot, use capital to best effect in this changed environment. That is precisely why it is needed, however uncomfortable the consequences might be.

What is actually needed therefore is clearly an approach rooted in this:

Diagram 3

This is the long term position most working in sustainability would, I believe, like to see. However there are differences of opinion in how to get there.

Kate Raworth argues that you may need to talk within Diagram 1 to start with in order to engage the finance professionals, which of course includes the central bankers and treasury official who might limit the speed at which we could move to Diagram 3. Others disagree, saying once you start talking to finance professionals in their own language, you are condemned to a solution in Diagram 1.

What seem clear to me is that, if our arguments are between Diagram 1 and Diagram 3, perhaps we can dispense with Diagram 2.

A success made of failures

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

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

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

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

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

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

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

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

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

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

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

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

Augar, Climate Impact and Skill Shortages

31. July 2020 · Write a comment · Categories: Climate Change

I am just at the start of exploring the Green New Deal (GND), how it might work in the UK and its implications for the economy more generally. I have decided to start in an area I know a little bit about, namely education and skills, but three charts have stood out for me already in suggesting that a number of seemingly unrelated current problems may have very related solutions.

The first comes from the Augar Review into post 18 education and funding. The discussion around this when it came out in May 2019 was predominantly on the recommendations concerning increased funding for FE colleges and changes to the funding arrangements for universities. However there was a lot more to the Review than this and this chart was the most striking for me.

As you can see we hardly have any Level 4/5 as the highest level of qualification in England. What is Level 4/5? Well Level 3 means A levels, a BTEC Diploma or a craft qualification. Level 6 means a degree. In between are Levels 4 and 5. Level 5 is Foundation degrees, Higher National Diplomas (HNDs), Diplomas of Higher Education (DipHEs) and Level 4 is Higher National Certificates (HNCs), full Accounting Technician qualifications, etc.

As the Review says (my highlights in bold):

In England, only 4 per cent of 25 year-olds hold a Level 4 or Level 5 qualification as their highest level, compared to nearly 30 per cent for both Level 3 and Level 6. In contrast, in Germany, Level 4 and 5 makes up 20 per cent of all higher education enrolments.

Those few who do obtain a Level 4 or 5 award – often by a rather circuitous route – move into well-paid skilled jobs; the median annual income of someone with a Level 4 or 5 is around £2,000 higher than someone with a Level 3 by the age of 26 and comparable to the earnings of some graduates. Similarly…Level 3 apprenticeships in the skilled trades and engineering are very highly valued by employers – indeed in the latter case, for men at age 28, more than some Level 6 degrees. However…apprenticeship in England has in recent years been concentrated at lower levels (typically Level 2) than is common in the rest of Europe. Skill shortages in contrast are most evident at Levels 3 and above.

Employers have dealt with some skills shortages (for example in construction) by hiring recent immigrants with the relevant skills. They have also responded to the lack of Level 4 or 5 qualified applicants by taking on graduates as technicians, although without the relevant practical training graduates are often actually under-skilled for such roles and tend to leave quickly.

England’s education and training system currently stands in the way of taking on technician apprentices in emerging and small sectors. With no central mechanism for ensuring coverage, some employers have told us that it is often hard to identify colleges or other training providers willing to provide the necessary education and training. Providers will only do so if they are assured of a critical mass of apprentices, since otherwise the training is financially non-viable – especially if it requires expensive equipment.

The second chart or diagram comes from the paper called A net-zero emissions economic recovery from COVID-19 from the Oxford Smith School. This looks at the potential impact on reducing carbon emissions on the vertical axis and the long run multiplier (ie the increase in national income as a result of a stimulus to the economy). The obvious things to concentrate on in such a chart are those in the top right quadrant, ie high impact both environmentally and economically. The five areas unambiguously in this quadrant are Y (Clean research and development (R&D) spending), T (Clean energy infrastructure investment – ie alternatives to fossil fuels), S (Connectivity infrastructure, particularly broadband), X (General R&D spending) and L (Education investment).

And the final chart comes from the employer skills survey 2017 from the Department for Education in August 2018 (the latest one to emerge so far). This shows the vacancies due to there being insufficient people with the appropriate skills to fill them.

This should perhaps be considered in conjunction with the following very interesting comparison between the sectors where jobs are available and those where 17-18 year old typically would prefer to work (from Disconnected: Career aspirations and jobs in the UK by Chambers et al):

And this is before the big increases in skilled technicians in skilled trades, and in both scientific and technical areas and professional and managerial areas that a GND will require, coupled with the transformation of our economy as a result of the fourth industrial revolution that appears to be anticipated, at least in part, by the 17-18 year olds answering the survey. As the 2020 Progress Report to Parliament from the Committee on Climate Change on Reducing UK Emissions from last month says:

There are clear economic, social, and environmental benefits from immediate expansion of the following measures (again, my highlights in bold):

Investments in low-carbon and climate-resilient infrastructure.
Support for reskilling, retraining and research for a net-zero, climate-resilient economy.
Upgrades to our homes and other buildings ensuring they are fit for the future.
Action to make it easy for people to walk, cycle, and work remotely.
Tree planting, peatland restoration, green spaces and other green infrastructure.

Three different problems, all with a major part of their solution in the reconfiguration of our further and higher education systems to skill and reskill, train and retrain, the generations we are relying on to secure all our futures. It looks like a good place to start!

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

30. March 2020 · Write a comment · Categories: Actuarial, Climate Change, Economics, Prediction, Risk

“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.

Actuaries and the Event Horizon

18. January 2020 · Write a comment · Categories: Actuarial, Climate Change, Economics

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.

A possible manifesto for the next generation

06. December 2019 · Write a comment · Categories: Climate Change, Demographics, Economics

I am an actuary. I have worked for over 22 years either in, or serving in some capacity (apart from the two years I spent learning to be a teacher), the finance industry. I spent the 12 years before that mostly either bringing up children or writing unpublishable novels, with some early career experiences in the security printing industry thrown in which I thank principally for teaching me early that no way of doing things is for ever. Seven of my former employers no longer exist, mostly swallowed up in subsequent corporate transactions. I am increasingly convinced that a “career” like mine is no longer possible for the next generation, and my most recent evidence for this is based predominantly on two excellent books.

The first is The Finance Curse by Nicholas Shaxson. This demonstrates, convincingly, that a huge part of our current malaise as a nation, whether it is the loss of control over our own affairs, or the current, Victorian, levels of inequality or the fact that we don’t appear to invest in any of things we need to prosper as a society any more, can be traced back ultimately (sometimes via very cunning circuitous routes) to the Faustian pacts the City of London have lobbied the rest of us into with the rest of the world.

The second is The Pinch by David Willetts (and link to his slides – one of which is shown above – on it from 2015 here), whose central argument is that we are not attaching sufficient value to the claims of future generations, and that this is an intellectual failure of my generation: the one that spawned both me and Boris Johnson. I will declare an interest here: David is Chancellor at the University of Leicester, where I work as an actuarial science lecturer, in addition to all of his many other achievements and will be speaking at the Leicester Actuarial Science Society on 11 March on intergenerational fairness linked to a new edition of his book.

So for any highly talented twenty-somethings looking to make his or her mark in the world (and I have been privileged to meet and teach many of you over the last few years), I would, very hesitantly (because you probably don’t need me of all people to be giving you an agenda), suggest that the following things might be a priority for your generation:

Don’t be distracted by the short term. Most people now want action on climate change, for instance, which has been delayed to a ridiculous extent by our inability to place sufficient value on the needs of future generations. Most of the things worth working towards and campaigning on are long-term problems with solutions which require long-term patient consensus-building. Our generation have been unable to do this seriously, yours cannot afford to be so distracted.
Stay focused on the big issues: What is the proper allocation of wealth between the generations? Most of the problems we fixate on, like obesity or anti-social behaviour or credit card debt are just symptoms of the breakdown of the inter-generational contract which the baby boomers (because we felt that we could do so because of our greater numbers) have visited upon our societies. We have then presumed to pass moral judgement on the generation we have so comprehensively wronged, which is of course an easier message for many in our generation to hear but is one of the main reasons we have become too distracted to deal with the big long-term issues that we face as a society.
Don’t make it all about good guys and bad guys. It is easy to vilify individuals in this great inter-generational psychodrama that we have all been living through, and it might make you feel momentarily more empowered or encouraged as a result, but in the long term the power is with you anyway and you will be more effective if you make it about good and bad systems. Good systems pursue the interests of our own people, whereas bad systems pursue the interests of people who need to be persuaded to invest in our society but have no real long term interest in doing so: ie other societies who clearly need to prioritise their own people’s needs and tax avoiding multinational companies and individuals.

I would like to finish with the concluding sentences of The Pinch:

The modern condition is supposed to be the search for meaning in a world where unreflective obligations to institutions or ways of doing things are eroded. The link between generations past, present and future is a source of meaning which is as natural as could be. It is both cultural and economic, personal and ethical. We must understand and honour those ties which bind the generations.

In the nine years since The Pinch was published we have done the very opposite of honouring the ties which bind the generations. We must hope that the generation following us have more wisdom.

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.

Dr Strangelove’s Pension

01. May 2019 · Write a comment · Categories: Actuarial, Climate Change, Economics, Pensions, Prediction, Regulation, Risk

The War Room with the Big Board from Stanley Kubrick’s 1964 film, ”Dr. Strangelove”. Source: ”Dr. Strangelove” trailer from 40th Anniversary Special Edition DVD, 2004 Directed by Stanley Kubrick

In 1960, Herman Kahn, a military strategist at the RAND Corporation, an influential think tank which continues to this day, wrote a book called On Thermonuclear War. It focused on the strategy of nuclear war and its effect on the international balance of power. Kahn introduced the Doomsday Machine (which Kubrick used in his film “Dr Strangelove” alongside many other references from the book) as a rhetorical device to show the limits of John von Neumann’s strategy of mutual assured destruction or MAD. It was particularly noteworthy for its views on how a country could “win” a nuclear war.

For some reason Kahn came to mind as I was looking through Resource and Environment Issues: A Practical Guide for Pensions Actuaries, from the Institute and Faculty of Actuaries’ Relevance of Resource and Environment Issues to Pension Actuaries working party, which summarises the latest thinking on the climate change-related issues scheme actuaries should be taking into consideration in their work. I will come back to why.

The section which particularly caught my attention was called How might pensions actuaries reflect R&E issues in financial assumptions? This section introduces two studies in particular. First, we have the University of Cambridge Sustainability Leadership (CISL) report on Unhedgeable risk: How climate change sentiment impacts investment. This posits three “sentiment” scenarios (paraphrased slightly for brevity – see the report for details of the models used):

Two degrees. This is defined as being similar to RCP2.6 and SSP1 from the Intergovernmental Panel on Climate Change (IPCC) AR5. Resource intensity and dependence on fossil fuels are markedly reduced. There is rapid technological development, reduction of inequality both globally and within countries, and a high level of awareness regarding environmental degradation. It is believed that under this scenario global warming will not raise the average temperature by more than 2°C above pre-industrial temperatures.
Baseline. This is a world where past trends continue (i.e. the business-as-usual scenario), and there is no significant change in the willingness of governments to step up actions on climate change. However, the worst fears of climate change are also not expected to materialise and temperatures in 2100 are only expected to reach between 2°C and 2.5°C. This scenario is most similar to the IPCC’s RCP6.0 and SSP2. The economy slowly decreases its dependence on fossil fuel.
No Mitigation. In this scenario, the world is oriented towards economic growth without any special consideration for environmental challenges. This is most similar to the IPCC’s RCP8.0 and SSP5. In the absence of climate policy, the preference for rapid conventional development leads to higher energy demand dominated by fossil fuels, resulting in high greenhouse gas emissions. Investments in alternative renewable energy technologies are low but economic development is relatively rapid.

The modelled long-term performance for a range of typical investment portfolios is worrying:

CISL suggest quite different investor behaviour depending upon which climate change path they think the world is taking: moving into High Fixed Income if No Mitigation seems to be the direction we are heading, but adopting an Aggressive (ie 60% equities, 5% commodities) asset allocation if the Two Degrees scenario looks most likely.

Elsewhere the report suggests hedging via cross-industry diversification and investment in sectors with low climate risk. For example under No Mitigation, it is possible to cut the maximal loss potential by up to 47% by shifting from Real Estate (in developed markets) and Energy/ Oil & Gas (in emerging markets) towards Transport (in developed markets) and Health Care/ Pharma (in emerging markets). However over 50% of losses in all scenarios remain unhedgeable (ie unavoidable through clever asset allocation alone).

The second report (Investing in a time of climate change) from Mercer in 2015, focuses on the following investor questions:
• How big a risk/return impact could climate change have on a portfolio, and when might that happen?
• What are the key downside risks and upside opportunities, and how do we manage these considerations to fit within the current investment process?
• What plan of action can ensure an investor is best positioned for resilience to climate change?

The section I was drawn to here (it’s a long report) was Appendix 1 on climate models used, and particularly those estimating the physical damages and mitigation costs associated with climate change. The three most prominent models used for this are the FUND, DICE and PAGE models, apparently, and Mercer have opted for FUND. They have then produced some charts showing the difference between the damages exepcted for different levels of warming predicted by the FUND model compared to DICE:

The result of this comparison, showing lower damage estimates by the FUND model, led the modellers to “scale up” certain aspects of the output of their model to achieve greater consistency.

Both of these reports have been produced using complex models and a huge amount of data, carefully calibrated against the IPCC reports where appropriate and with full disclosure about the limitations of their work, and I am sure they will be of great help to pension scheme actuaries (although there does some to be some debate about this). However I do wonder whether as a profession we should be spending less time trying to find technical solutions in response to worse and worse options, and more time trying to head off the realisation of those sub-optimal scenarios in the first place. I also wonder whether the implicit underlying assumption about functioning financial markets and pension scheme funding is a meaningful problem to be grappled with at 3-4° above pre-industrial averages as some of this analysis suggests.

In the summary of Mark Lynas’ excellent book Six Degrees: Our Future on A Hotter Planet, 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 Amazonian rain forest basin will dry out completely. In Brazil, Venezuela, Columbia, East Peru and Bolivia life will become increasingly difficult due to wild fires which will cause intense air pollution and searing heat. The smoke will blot out the sun. Drought will be permanent in the sub-tropics and Central America. Australia will become the world’s driest nation. In the US Gulf of Mexico high sea temperatures will drive 180+ mph winds. Houston will be vulnerable to flooding by 2045. Galveston will be inundated. Many plant species will become extinct as they will be unable to adapt to such a sudden change in climate.

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 last time the world experienced a three degree temperature rise was during the geological Pliocene Age (3 million years ago). The historical period of the earth’s history was undoubtedly due to high CO2 levels (about 360 – 440ppm – almost exactly current levels). I would suggest that our biggest problem under these conditions is not that over 50% of losses on pension scheme investments remain unhedgeable.

In his recent article for Social Europe, the unbearable unrealism of the present, Paul Mason presents two graphs. The first is the projection by the United States’ Congressional Budget Office of the ratio of debt to gross domestic product until 2048 in the United States.

The second is a chart from the IPCC showing how dramatically we need to cut CO2 emissions to avoid catastrophic and uncontrollable breakdown.

Mason feels that capitalism is too indebted to go on as normal and too structurally addicted to carbon. In his view Those who are owed the debt, and those who own rights to burn the carbon, are going to go bankrupt or the world’s climate will collapse. This feeling is echoed by George Monbiot here, where he cites a paper by Hickel and Kallis casting doubt on the assumption that absolute decoupling of GDP growth from resource use and carbon emissions is feasible and summarises some alternative approaches to the capitalism he feels no longer has the solutions.

Others dispute this, claiming that the Green New Deal is the only chance we have (here, here and here) to prevent irreversible climate change.

Whether you agree with any of these predictions or none of them, agree that we face a climate emergency or feel that is too extreme a description, it all brings me back to Kahn and Dr Strangelove. We seem to have replaced the MAD of the cold war with the MAD of climate change, except that this time we do not even have two sides who can prevent it happening by threatening to unleash it on each other. It is just us.

What we really cannot afford to be doing, via ever more complex modelling and longer and longer reports, is giving the impression that the finance industry can somehow “win” against climate change rather than joining the efforts to avert it as far as possible.
