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.

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:

  1. 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.
  2. 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.
  3. 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.

 

Business macroeconomics for actuarial students – the first year

24. June 2019 · Write a comment · Categories: Actuarial, Economics

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!

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.

The Bullshit Alternative

30. June 2018 · Write a comment · Categories: Actuarial, Economics, Legal, Prediction, Regulation

I have seen two very different pictures of the future of professional life over the last year or so. The first, which I wrote about over a year ago, was presented in The Future of the Professions by Richard and Daniel Susskind, and has been much debated since within the actuarial profession for what the implications might be for the future. In summary, the Susskinds set out two possible futures for the professions. Either:
• They carry on much as they have since the mid 19th century, but with the use of technology to streamline and optimise the way they work;
• Increasingly capable machines will displace the work of current professionals.

Their research suggests that, while these two futures will exist in parallel for some time, in the long run the second future will dominate. Indeed Richard Susskind has gone further in setting out what that future might look like for the legal profession, where he sets out future strategies for surviving in a world of increasingly capable machines as:

  • providing more for less (ie charging less (in particular the end of time cost fees), alternative billing arrangements such as “value billing”, making efficiencies and collaboration strategies where clients come together to share costs);
  • liberalising services (ie allowing a wider range of people to provide legal services); and
  • technology (ie online services in all of their forms to make the delivery of these cheaper, increasing use of data scraping, text mining, etc to replace what was previously done through expert judgement).

So far, so expected. The relentless increase in technological capability is bound to demand increased efficiency and leaner organisations competing ruthlessly in a pitiless market, right?

Enter an alternative vision for the future. Pointing out that we have been here before and that Keynes had speculated in 1930 that

In quite a few years – in our own lifetimes I mean – we may be able to perform all the operations of agriculture, mining, and manufacture with a quarter of the human effort to which we have been accustomed.

David Graeber, in his latest book Bullshit Jobs, points out that this never happened, despite pretty much all of the technological developments and income increases which Keynes predicted. He suggests that this future which the Susskinds are predicting is already happening in terms of needing fewer people to fill the meaningful roles within organisations but that, rather than employing fewer people, we are either creating “bullshit” jobs which even the people doing them can see no point to or bullshitizing existing roles for which the meaningful need has passed. It is as if the organisations themselves have attempted to maintain the outward appearance of the same structures by disguising the hollowing out of so many of their functions with simulated business.

It is an intriguing alternative vision of how the professional world might develop which has come in for some criticism, the most serious of which Graeber attempts to address in his book. One of the reasons he thinks the situation has been allowed to develop is that noone believed that capitalism could produce such an outcome. But that is only if you accept the rational profit maximising principle, which many economists have now abandoned as an explanation for corporate or individual behaviour. Graeber gives one particularly important example of this in the creation of Obamacare, where Barack Obama “bucked the preferences of the electorate and insisted on maintaining a private, for-profit health insurance system in America”, quoting him as follows:

“I don’t think in ideological terms. I never have,” Obama said, continuing on the health care theme. “Everybody who supports single-payer health care says, ‘Look at all this money we would be saving from insurance and paperwork.’ That represents one million, two million, three million jobs [filled by] people who are working at Blue Cross, Blue Shield or Kaiser or other places. What are we doing with them? Where are we employing them?”

So which vision of the future is more likely? I think, at the moment, there is probably more evidence for the Susskind vision, mainly because he has been working in this area for 30 years and therefore many of his predictions, such as the use of email to provide legal advice, have had time to emerge. Many of the stories in Graeber’s book ring true for me and are similar to experiences I have had at times myself, but he has only obtained 300 of them. The YouGov poll which highlighted that 37% of working adults say their job is making no meaningful contribution to the world – but most of them aren’t looking for another one, was based on a sample size of 849. There was also a similar result (in this case 40%) from a survey in the Netherlands, for which I couldn’t easily find the sample size. However this does also lend some weight to one of Graeber’s other contentions in the book that the financial industry might be considered a paradigm for bullshit job creation, as the following graph (from a working paper on this issue by Stolbova et al) shows that the Netherlands and the UK are by far the most financialised economies in the EU.

There are other parts which ring less true for me. For instance, I do not recognise the alternative “non-managerial” university exam paper production process to that shown below (which is just the academic staff sending the exam to a teaching assistant to print and the teaching assistant confirming that he/she has done so) as ever having been remotely acceptable, but this may just reflect the fact that I have been working in academia for a far shorter time than Graeber. However there is no doubt that this is an interesting and useful field of enquiry and potentially concerning for all of us trying to support our graduates in negotiating a meaningful and rewarding entry into the workplace.

There is likely to be significant disruption over the next couple of decades in how we do things and it seems likely to me that there will be many seeking to protect familiar organisational and power structures along the way, as our assumptions about what we want and how we are prepared to have it provided to us are seriously challenged in sometimes unnerving ways. Of the sustainability of these protections ultimately, I am less sure.

Bring Two Brains’ Hammer Inside the Tent

While the NHS has been asked to find £22 billion in savings by 2020, the latest figures from the Student Loans Company show that over £13 billion has been found to fund student loans for 2016/17 alone, without increasing the Government’s deficit and without appearing in the Public Sector Borrowing Requirement until some time in the 2040s. How is this possible?

The key difference is that the money the Government provides in student loans are seen as just that: loans. However, unlike any other kind of loan (and the reason that commercial banks declined to join the SLC – which was the original plan and the reason it was set up with a company structure), only between 40 and 45% is expected ever to be repaid, the repayment term is limited to a maximum of 30 years and the payments limited to a percentage of earnings above a minimum earnings threshold (which is about to increase to £25,000 pa). It is in reality a graduate tax masquerading as a loan, with the “sticker price” of £9,250 pa (which is of course a real price for overseas students) just used to ensure students don’t feel like they are paying this tax on someone else’s behalf. However the payments made by the Government since 2011 as “loans” have not led to any outcry about uncosted commitments, or passing the bill onto future generations which you might expect. Which is surprising, as it has meant that Higher Education has effectively been allowed to sidestep the austerity policies applied to just about every other Government department completely.

One might think that the architect of such a scheme would be quite popular within the Higher Education space. Far from it. Since the announcement of his appointment as the new Chancellor at the University of Leicester, the Leicester branch of the UCU has widened the campaign it is already running against the Joint Negotiating Council’s decision to close the USS pension scheme to further defined benefit accrual to embrace a #WillettsOut position. The students who occupied the corridor outside the Leicester VC’s office for two days similarly had Willetts’ removal on their list.

Apart from elements of his voting record (he was strongly in favour of an elected House of Lords and was strongly against the ban on fox-hunting. TheyWorkForYou additionally records that, amongst other things, he was strongly in favour of the Iraq War, strongly in favour of an investigation into it, moderately against equal gay rights, and very strongly for replacing Trident), the main charges against him seemed to date from an article about him in the Guardian from 2011.

Now without minimising the differences of opinion which I and many of my colleagues will clearly have with David Willetts on a wide range of issues, I do think we are in danger of surrounding ourselves with the comfortable cushions of like-minded individuals all equally in the dark about the regulatory changes in store for us and at risk of all the worst consequences of Group Think. I would therefore like to put forward an alternative view.

The University of Leicester is facing, along with the rest of the Higher Education sector, serious challenges over the coming decades in response to an expansion of the proportion of young people going to university which no political party is going to want to reverse (and which I, for one, would not want them to). David Willetts was the chief driver of much of these reforms and has a clear vision of what they are trying to achieve, set out in his book A University Education. He is currently a visiting professor at King’s College London where he works with the Policy Institute at King’s, a visiting professor at the Cass Business School, Chair of the British Science Association, a member of the Council of the Institute for Fiscal Studies and an Honorary Fellow at Nuffield College, Oxford. However his real passion is around social mobility, something which I believe is important to many of us here at Leicester, and which has led him to a role as Executive Chair of the Resolution Foundation. As a former cabinet minister and shadow cabinet minister from 1996 until 2014, Willetts is very well connected, a formidable debater and would make a fierce friend of the University, fighting Leicester’s corner in what is likely to be an increasingly challenging period.

David Willetts would undoubtedly bring significant challenge with him. Arguing with him (I watched him in debate with Stefan Collini and a variably outraged university audience at the Senate House last year) can sometimes feel like doing battle with a hammer. But it may be that this is what we need to respond successfully to the new world which is coming rather than yet another comfortable cushion to make us feel better. Let’s welcome him inside the tent.

We are paying too much attention to the wrong actuaries’ index

03. September 2017 · Write a comment · Categories: Actuarial, Climate Change, Economics, Prediction, Risk

The FTSE All-Share Index, originally known as the FTSE Actuaries All Share Index, along with the FTSE 100, represent nearly all of the market capitalisation and the top 100 companies by size listed on the London Stock Exchange respectively. They are mentioned in all BBC news bulletins. When they go up, we all feel better. When they go down, they are seen as portents of doom.

Let me show you a different actuaries’ index instead:

Figure 1 shows the ACI and each of the components. The composite ACI represents the average of the six components (with sign of change in cool/cold temperatures reversed). The ACI is increased by reduction in cold extremes, consistent with increased melting of permafrost and increased propagation of diseases, pests, and insects previously less likely to survive in lower temperatures. A positive value in the ACI represents an increase in climate-related extremes relative to the reference period.

The threat of climate change is real, independent of speculative trading and the news media cycle, and increasing with each degree of warming we are unable to stop. Alongside this are the increasing risks of extreme weather events, which is most neatly described for North America currently by the Actuaries Climate Index. This focuses on six components in particular which have the most impact on human societies:

  1. Frequency of temperatures above the 90th percentile (T90);
  2. Frequency of temperatures below the 10th percentile (T10);
  3. Maximum rainfall per month in five consecutive days (P);
  4. Annual maximum consecutive dry days (D);
  5. Frequency of wind speed above the 90th percentile (W); and
  6. Sea level changes (S).

It then tracks them all over time, as shown in the graph above.

It seems clear to me that we should be reacting much less to the booms and busts of economic cycles and much more to climate-related threats. This is for two main reasons:

1. More people are at threat of death or injury as a result of climate change than even the 2008 crash in our financial systems. The World Health Organisation (WHO) predicts that, between 2030 and 2050, climate change is expected to cause approximately 250,000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. However, the additional deaths are already here. Taking just two examples from the WHO:

  • In the heat wave of summer 2003 in Europe for example, more than 70,000 excess deaths were recorded, with the frequency of such events steadily increasing.
  • Globally, the number of reported weather-related natural disasters has more than tripled since the 1960s. Every year, these disasters result in over 60,000 deaths, mainly in developing countries, which means that 40,000 of those deaths pa can already be directly attributed to climate change.

On the other hand, the 500,000 additional cancer deaths and 10,000 additional suicide deaths since 2008 cannot be attributed directly to the 2008 crash, as the analysis shows. These are more a result of the austerity policies which have been applied since 2008. Unnecessarily.

Climate change on the other hand does not care whether we react to it or not. It will relentlessly change the chemistry and biology of everything around us as the Earth and the inhabitants of the Earth adapt. We may survive it, in reduced numbers, or we may not. The Earth does not care. Responding to the threat will not make more climate-related events happen unless our response is to, by and large, ignore it.

2. One depends on the other. We cannot base our economies on a FTSE-led GDP-growth-at-all-costs model because it is not physically possible to maintain it without losing the environment from which our growth originates. As Finbarr Livesey points out in his excellent From Global to Local, the circular economy which the overwhelming consensus of studies show would increase employment and contribute to economic growth is taking a long time to arrive. In Europe, where we consume around 16 tonnes of stuff each per year, figures from Siemens in 2016 suggest that 95% of it and its energy value is lost through the life cycle of the products themselves.  As Kate Raworth  and others have pointed out, we need to focus on different measures of success if we are going to direct our economies in a more sustainable, less volatile and doom-laden direction.

There are plans to extend the Actuaries Climate Index to Europe (including the UK in this instance!), with a recent feasibility study concluding “that the prospects for constructing an analogue to the Canada-US ACI over the European region are promising”. I hope we see such an index soon, because, as Randall Munroe illustrates here, we have not been here before.

I look forward to the day when a new global actuaries’ climate index is on every news bulletin, making us feel better when it goes down and seeing any rise as a portent of doom. Because this time it really would be.

Pensions and the Zombie Apocalypse

12. March 2017 · Write a comment · Categories: Actuarial, Demographics, Economics, Pensions

If the models are correct we are heading for a Zombie Apocalypse

Let’s forget the strapline of this blog for a moment and assume that the models are correct. The Pension Protection Fund (PPF) is targeting “self-sufficiency” by 2030, ie no more levies from sponsors of pension schemes required for it to independently fund all the future benefits of every scheme member whether they are already in the PPF or going to end up in it with only the insufficient assets their former employers allocated to their former pension schemes for company. BHS has concluded a very high profile deal in the last couple of weeks to set up a new self-sufficient scheme for its former employees. The Universities Superannuation Scheme (USS) has proposed a funding plan which targets self-sufficiency less a “covenant” (ie amount of money feasible to get out of the university sector in the future) by 2031. John Ralfe mentioned a few other examples in his article from 2015.
These are schemes which have been dubbed “zombie” schemes on the basis that they are basically dead, with no new money or new members coming in, but nevertheless dragging themselves along the floor year after year until all of their members have stopped twitching.
What does the UK pensions world look like in 2030? Well according to various sources:
• UK population will have increased to 70.6 million (assuming Scotland and Northern Ireland are still in it) with 21.4% of them over the age of 65 (S&P)
• Credit rating of UK will have fallen to A, with a further fall to BBB by 2035 assuming no change in economic policy (also S&P)
• Average life expectancies at birth in UK would be over 85 for women and 82.5 for men (Imperial College and WHO)
• Benefit outgo from defined benefit pension schemes is £100 billion more than contribution income pa (Hymans Robertson)

This does not sound like a happy place for our zombies to be negotiating with the occasional limb getting torn off as multiple doors are slammed in their faces. Although the self-sufficiency route is now a common approach amongst large schemes, it is largely untested. No scheme as far as I am aware has actually managed to run in a self-sufficient manner for any appreciable length of time, whereas the more expensive buy out route (where the benefits for members are purchased in the form of contracts with an insurer) is by comparison well established.

So off into this volatile landscape our zombies will be let loose, trying to run themselves like little insurance companies, but without the scale or diversification or experience which makes insurers (mostly) survive for long periods. However that better track record comes at a price which schemes are currently reluctant to pay. There is a good chance that this experiment will not end well.

My guess for 2030? That the volatile landscape will have claimed some casualties amongst the self-sufficient zombies and put them into the PPF with much bigger deficits than if they had gone there straight away. And then all the other zombies will T-U-R-N A-R-O-U-N-D V-E-R-Y S-L-O-W-L-Y and follow them there. At which point the PPF will realise that they are undead no longer.
