Dr Strangelove’s Pension

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.

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:

Frequency of temperatures above the 90th percentile (T90);
Frequency of temperatures below the 10th percentile (T10);
Maximum rainfall per month in five consecutive days (P);
Annual maximum consecutive dry days (D);
Frequency of wind speed above the 90th percentile (W); and
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.

The future for actuaries

Daniel and Richard Susskind in their book “The Future of the Professions” 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. The actuarial profession is particularly vulnerable. As the Susskinds write:

Accountants and consultants, for example, are particularly effective at encroaching on the business of lawyers and actuaries.

Actuaries both here and in other countries are waking up to what is coming, but the response of the profession is a whole has been quite slow.

For the actuarial profession, we will see the extension of some trends which have already begun, eg:

Automation of processes not just leading to greater efficiencies but reconfiguring both what work is done and how it is done, eg propensity pricing and pensions valuations
Para professionalization, like CAA Global for instance
Globalisation
Specialisation
Mergers of businesses as markets consolidate
Flexible self employment

And the emergence of trends that have hardly started at all yet, eg:

The end of reserved roles for actuaries
Different ways of communicating advice (Richard Susskind got into trouble with the Law Society in the mid 1990s for suggesting that most legal communication between lawyers and their clients would be delivered via email in the future, which would strike us as an obvious observation now)
Online self-help for users of actuarial advice (ask discussed by the Pensions Policy Institute in their report last year)
The advance of roboactuaries and their assistants

Focusing on the last of these, a paper produced by Dodzi Attimu and Bryon Robidoux for the Society of Actuaries in July 2016 explored the theme of robo actuaries, by which they meant software that can perform the role of an actuary. They went on to elaborate as follows:

Though many actuaries would agree certain tasks can and should be automated, we are talking about more than that here. We mean a software system that can more or less autonomously perform the following activities: develop products, set assumptions, build models based on product and general risk specifications, develop and recommend investment and hedging strategies, generate memos to senior management, etc.

They then went on to define a robo actuarial analyst as:

A system that has limited cognitive abilities but can undertake specialized activities, e.g. perform the heavy lifting in model building (once the specification/configuration is created), perform portfolio optimization, generate reports including narratives (e.g. memos) based on data analysis, etc. When it comes to introducing AI to the actuarial profession, we believe the robo actuarial analyst would constitute the first wave and the robo actuary the second wave

They estimate that the first wave is 5 to 10 years away and the second 15 to 20 years away. We have been warned.

One of the implications of this would be far fewer actuarial students required and, in my view, a much smaller appetite amongst actuarial firms for employing students while they were sitting actuarial examinations, particularly the core rather than specialist ones. This in turn would suggest an expansion of the role of universities in supporting students through these stages of their actuarial education, massively increasing the IT and data analysis skills of the next generation of actuarial students and developing far more opportunities for students to develop skills more traditionally seen as “work-based”, such as presentation, project management and negotiation skills. Some universities, such as my own at the University of Leicester, are using the preparatory work in anticipation of the Institute and Faculty of Actuaries’ launch of Curriculum 2019 to do all of these things.

But universities and the education professionals in general face their own challenges from the rise of technology and increasingly capable machines:

The development of learning labs offering personalised learning systems
Online education networks, like Moodle, once used just to support traditional university teaching activities, but now starting to actively supplant them
Other online education platforms, like the Khan Academy
The rise of Massive Open Online Courses or MOOCs. For instance, more people have signed up to Harvard University’s MOOCs in one year than have enrolled at the University in its 377 year history

The actuarial profession and the higher education sector therefore need each other. We need to develop actuaries of the future coming into your firms to have:

great team working skills
highly developed presentation skills, both in writing and in speech
strong IT skills
clarity about why they are there and the desire to use their skills to solve problems

All within a system which is possible to regulate in a meaningful way. Developing such people for the actuarial profession will need to be a priority in the next few years.

Of course it is still possible to laugh at what Artificial Intelligence and Machine Learning (here and here) have not managed to do yet, despite their vast ambitions. But it should not blind us to the fact that those ambitions will be realised in our working lifetimes in many cases. And we need to start preparing now.

Actuaries and Climate Change

30. April 2017 · Write a comment · Categories: Actuarial, Climate Change, Demographics, Legal, Pensions, Prediction, Risk

The Institute and Faculty of Actuaries (IFoA), through its Actuarial Research Centre, is inviting research teams and organisations to submit proposals for a research project on modelling pension funds under climate change. The research is intended to address the need for pensions actuaries to understand the potential magnitude of climate change impacts, and hence if and when climate change might be relevant to the funding advice they give. What areas in particular might be useful to look at through the lens of a pension actuary?

The current concentration of carbon dioxide in the Earth’s atmosphere is around 400 parts per million by volume (ppmv), or a little over 140% of the generally accepted pre-industrial level of 280 ppmv. What level we can cap this at depends on how we respond in every country in the world. There are therefore many opinions about it:

Source: IPCC AR5: Fig 2.08-01

Here RCPs stand for Representative Concentration Pathways, and are meant to be consistent with a wide range of possible changes in future anthropogenic (i.e. human) greenhouse gas emissions. RCP 2.6 assumes that emissions peak between 2010-2020, with emissions declining substantially thereafter. Emissions in RCP 4.5 peak around 2040, then decline. In RCP 6.0, emissions peak around 2080, then decline. In RCP 8.5, emissions continue to rise throughout the 21st century. What this means is that the best we can hope for now is a scenario somewhere between RCP 2.6 and RCP 4.5, with the US Government’s Environmental Protection Agency appearing to believe that RCP 6.0 is the most realistic scenario. As you can see, RCP 4.5 assumes an eventual equilibrium at around 500 ppm, or about 180% of pre-industrial levels and RCP 6.0 an equilibrium at around 700 ppmv, or about 250% ppmv.

Equilibrium climate sensitivity is defined as the change in global mean near-surface air temperature that would result from a doubling of carbon dioxide concentration. A doubling of the pre-industrial level to 560 ppmv (ie between the RCP 4.5 and RCP 6.0 assumption) has been projected to result in a range of possible outcomes:

Source: IPCC 2007 4th Assessment Report, Working Group 1 (Figure 9-20-1)

This is certainly a bit of a we know zero kind of graph, but has worryingly fat tails indicating reasonable chances of 10 degrees plus added to average global temperatures. To put this in context, let’s use the approach taken in Mark Lynas’ excellent “Six Degrees“, where the combined research into the effects of each additional degree above pre-industrial global temperatures is collated to allow us to view them as distinct possible futures. Some examples are as follows:

One degree

We are nearly here (around 0.8ᵒ so far):

Return of the “Mid-west American dust bowl” but with greater vengeance
Increase in hurricane activity
Loss of low lying islands, eg Tuvalu

Two degrees

The “safe” level we are trying to limit increases to:

Release of greenhouse gases begin to alter the oceans. May render some parts of southern oceans toxic to Ca CO3 and thus to one of life’s essential building blocks, plankton.
Heatwaves like 2003 which killed 35,000 people in Europe and led to crop losses of $12 billion and forest fires costing $1.5 billion will occur almost every other summer.
Crippling droughts can be anticipated in Los Angeles and California
From Nebraska to Texas the anticipated drought would be many times worse than the 1930s “dust bowl” phenomenon.
Polar bears would probably become rapidly extinct.
Mediterranean countries will become drier and hotter with significant water shortages.
IPCC estimate sea level rise of 18 to 59 cms.
Monsoons would increase in India and Bangladesh leading to mass migration of its populations.
International food price stability will have to be agreed to prevent widespread starvation.

Three degrees

Africa will be split between the north which will see a recovery of rainfall and the south which becomes drier. This drier southern phase will be beyond human adaptation. Wind speeds will double leading to serious erosion of the Kalahari desert.
Indian monsoon rains will fail. ·
The Himalayan glaciers provide the waters of the Indus, Ganges and Brahmaputra, the Mekong, Yangtze and Yellow rivers. In the early stages of global warming these glaciers will release more water but eventually decreasing by up to 90%. Pakistan will suffer most, as will China’s hydro-electric industry.
Amazonian rain forest basin will dry our completely with consequent bio-diversity disasters
Australia will become the world’s driest nation.
New York will be subject to storm surges. At 3° sea levels will rise to up to 1 metre above present levels.
In London, a 1 in 150 year storm will occur every 7 or 8 years by 2080.
Hurricanes will devastate places as far removed as Texas, the Caribbean and Shanghai.
A 3° rise will see more extreme cyclones tracking across the Atlantic and striking the UK, Spain, France and Germany. Holland will become very vulnerable.
By 2070 northern Europe will have 20% more rainfall and at the same time the Mediterranean will be slowly turning to a desert.
More than half Europe’s plant species will be on the “red list”
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. US southern states worst affected, Canada may benefit. The IPCC reckons that a 2.5° temperature rise will see food prices soar.
Population transfers will be bigger than anything ever seen in the history of mankind.

Three degrees obviously needs to be avoided, let alone ten, but the problem is that business as usual for the finance industry may not be the way to get there. As some recent research has suggested, financial market solutions to environmental problems, such as carbon trading, may be ineffective. As the authors state: By highlighting the tenuous and conflicting relation between finance and production that shaped the early history of the photovoltaics industry, the article raises doubts about the prevailing approach to mitigate climate change through carbon pricing. Given the uncertainty of innovation and the ease of speculation, it will do little to spur low-carbon technology development without financial structures supporting patient capital.

Patient capital is something developed economies have been seeking for some time, whether it is for infrastructure investment, development projects or new energy sources, and no good way to create it within the UK private sector has been found yet, including various initiatives to try and get an increase in pension scheme investment in infrastructure projects. It therefore seems to me to be the wrong question to ask what impacts climate change are likely to have on the assumptions used for pension scheme funding, when it is the impact of the speculation which pension scheme funding encourages which is one of the main drivers of our economies towards the worst possible climate change outcomes.

A more productive research question in my view would be to bring in legislators and pensions lawyers as well as environmental scientists and others researching and thinking in this area alongside actuaries to look at how we could change the regulatory framework within which pension scheme funding and investment within other financial institutions where actuaries are central takes place. There is already research into what changes may be necessary to international law to reflect the new Anthropocene era the planet has entered, where the dominant feature is the impact of human activity on the environment. In my view this should be extended to the UK legislative and regulatory landscape too.

I don’t know who the winners and loser of the 2050s will be and neither do the PPI

06. April 2016 · Write a comment · Categories: Demographics, Pensions, Prediction

For a brief period this week, before the Panama leaks brought everyone back in the room, one of the BBC’s main headlines was that a change to the UK State Pension was projected to make around three-quarters of people currently in their 20s and two-thirds of those currently in their 30s worse off than under the current arrangements. Figures of £19,000 and £17,000 “over the course of their retirement” were bandied around.

The reason the analysis had been carried out by the Pensions Policy Institute (PPI) was that the Department of Work and Pensions (DWP) is required to carry out an impact assessment of such proposed changes and had given the PPI the task.

First of all, the full summary of the analysis, coverage of which on the BBC has at least started to become a little more measured by today, is as follows:

As you can see, the numbers that came out were weekly losses of up to £17 per week for some groups and weekly gains of up to £13 per week for others. These numbers were themselves based on complicated projections about how benefit changes would be phased in and also how much the State Second Pension would pay people many decades into the future (the DWP paper can be found here). They were then aggregated by multiplying by the number of weeks in retirement until the pensioner was expected to die, based on the current State Pension Age timetable and the principal projections from the ONS 2015 Life Tables. The total amounts expected to be paid to people in retirement, however, were not (for those in their 20s this would be around 24 x 52 x 155.65 (the start rate for the new State Pension) as a minimum = £194,250 in 2015 terms). Neither was any explanation made of just how many years people were being projected to live. For £17 a week to translate into £21,000, the person currently in their 20s will need to be in retirement for nearly 24 years. It is not clear exactly when this person is expected to retire: the current tables only go up to a date of birth of 6 April 1978 (when State Pension Age is expected to be 68) with a vague intention to increase it to 69 by the late 2040s. An assumption of a retirement age of 69 looks consistent with the projections, which indicate a life expectancy at that age of 22.95 years for males and 24.81 years for females born in 1995.

And that last bit leads me on to why this particular news story is in my view just foolish. I tend to get a bit crotchety whenever anyone projects anything as a fact to a date beyond my personal life expectancy (less than 33 more years, according to the ONS). We are talking about people being worse off in the 2050s and 2060s. Here are a few more projections for you with those kinds of timelines:

World population will be 9 billion by 2050 (UN – currently it’s 7 billion)
Total energy demand in CO2 equivalent doubles from current levels by 2060 (IPCC)
Banking assets in London exceed 9 times UK GDP by 2050 (Mark Carney, Governor of the Bank of England)
60% of government bonds across all countries will be classified as junk by 2050 (Standard & Poors)

The vast majority of people are going to be better off who retire in the next 15 years (at least in terms of their State Pension), as will most people retiring in the decade after that. Beyond that we are in the region of the unknowable – almost certainly a very different-looking world which will have required several further adjustments to state pensions before we get there. So please let’s not waste time having foolish arguments about made up winners and losers.

Simplicity, transparency and personal responsibility

31. August 2015 · Write a comment · Categories: Actuarial, Defined Ambition, Demographics, Economics, Pensions, Prediction, Regulation, Risk

The Treasury is consulting on the tax relief that should be available in future for pension schemes and their members. The principles for any reform that it has set out are:

it should be simple and transparent;
it should allow individuals to take personal responsibility;
it should build on the success of automatic enrolment; and
it should be sustainable.

Simplicity, transparency, personal responsibility and sustainability mean different things to different people, which means that the precise meaning of these principles will depend on the politics of the people proposing them. However the words themselves are difficult to argue with, which is presumably why they have been chosen.

It has then set out 8 questions that it would like answered in response to its consultation. The consultation ends on 30 September. I have set out my responses below. I hope that they will sufficiently incense one or two more people into making their views heard, before the chance disappears.

1. To what extent does the complexity of the current system undermine the incentive for individuals to save into a pension?

On this question I think I agree with Henry Tapper at the Pension PlayPen. He says the following:

In summary, millions of pounds of tax relief is wasted by the Treasury helping wealthy people avoid tax…Incentives are available to those on low earnings who pay no tax, but this message is not getting through, we need a system that resonates with all workers, not just those with the means to take tax advice.

I then think I agree with the following:

The incentive should be linked to the payment of contributions and not be dependent on the tax or NI status of the contributor – if people are in – they get incentivised.

That would certainly make the incentive to the pension scheme member clearer and potentially easier to understand. The other simplification I would support would be the merging of income tax and national insurance contributions – many of the sources I have referenced below are trying to solve problems caused by the different ways these two taxes are collected. This simplification would be an essential part of any pension reforms in my view.

2. Do respondents believe that a simpler system is likely to result in greater engagement with pension saving? If so, how could the system be simplified to strengthen the incentive for individuals to save into a pension?

This is the invitation to support TEE (ie taxed-taxed-exempt, the same tax treatment as for ISAs). I have up until now been persuaded by Andrew Dilnot and Paul Johnson’s paper from over 20 years ago that this was not a good idea. This pointed out that the current EET system:

Avoids problems with working out what level of contributions are attributable to individuals in a DB system
Does not discourage consumption in the future relative to consumption now

I have changed my mind. The first point has already been addressed in order to assess people against the annual allowance, although this may need to be further refined. The second point is more interesting. As Paul Mason has pointed out in Postcapitalism, the OECD 2010 report on policy challenges, coupled with S&P’s report from the same year on the global economic impacts of ageing populations point to the scenario pensions actuaries tend to refer to when challenged on the safety of Government bonds, ie if they fail then the least of your problems will be your pension scheme. The projections from S&P (see bar chart above) are that 60% of government bonds across all countries will have a credit rating below what is currently called investment grade – in other words they will be junk bonds. In this scenario private defined benefit schemes become meaningless and the returns from defined contribution schemes very uncertain indeed. A taxation system which seeks to extract tax on the way in rather than on the way out then looks increasingly sensible.

I think that both the popularity of ISAs and the consistently high take up of the tax free cash option by pensioners, however poor the conversion terms are in terms of pension given up, suggest that tax exemptions on the way out rather than on the way in would be massively popular.
3 Would an alternative system allow individuals to take greater personal responsibility for saving an adequate amount for retirement, particularly in the context of the shift to defined contribution pensions?

Based on my comments above, I think the whole idea of personal responsibility for saving adding up to more than a hill of beans for people currently in their 20s may be illusory. People do take responsibility for things they can have some control over. Pension savings in the late twenty-first century are unlikely to be in that category.
4 Would an alternative system allow individuals to plan better for how they use their savings in retirement?

As I have said I favour a TEE system like ISAs. I think some form of incentive will be required to replace tax exemption, such as “for every two pounds you put in a pension, the Government will put in one” with tight upper limits. The previous pensions minister Steve Webb appears to broadly support this idea. Exemption from tax on the way out (including abolition of the tax charges for exceeding the Lifetime Allowance) would also aid planning.
5 Should the government consider differential treatment for defined benefit and defined contribution pensions? If so, how should each be treated?

I think this is inevitable due to the fact that defined contribution (DC) schemes receive cash whereas defined benefit (DB) schemes accrue promises with often a fairly indirect link to the contributions paid in a given year. In my view taxation will need to be based on the current Annual Allowance methodology, perhaps refined as suggested by David Robbins and Dave Roberts at Towers Watson. The problem with just taxing contributions in DB is that you end up taxing deficit contributions which would effectively amount to retrospective taxation.

A further option discussed in Robbins and Roberts is making all contributions into DB schemes into employee contributions. I would go further and apply this to both DC and DB schemes – a sort of “reverse salary sacrifice” which could be encouraged by making the incentives on contributions only available on employee contributions, which would then be paid out of net pay. Any remaining accrual contributions made by employers in a DB scheme would be taxed by an adjustment to the following year’s tax code.
6 What administrative barriers exist to reforming the system of pensions tax, particularly in the context of automatic enrolment? How could these best be overcome?

I think everything points to the need for the retirement of DB for all but the very largest schemes. It would be better to do this gradually starting soon through an accelerated Pension Protection Fund (PPF) process rather than having it forced upon us in a hurry later in the century when PPF deficits may well be considerably higher than the current £292.1 billion.
7 How should employer pension contributions be treated under any reform of pensions tax relief?

As I have said, I think they should be converted into employee contributions based on higher employee salaries. This would make it clearer to people how much was being invested on their behalf into pension schemes.
8 How can the government make sure that any reform of pensions tax relief is sustainable for the future.

They can’t, and any change now will almost certainly be revisited several times over the next 50 years. However, systems where people feel they can see what is going on and which are tax free at the end are currently very popular and I would expect them to remain so for the foreseeable future. That takes care of political sustainability in the short term. What about longer-term economic sustainability? Faced by an uncertain and turbulent next 50 years where I have argued that personal responsibility (rather than communal responsibility) for pensions will seem increasingly irrelevant, I think what I have proposed will allow us to transition to a system which can be sustained to a greater degree.

We are entering what may prove to be a traumatic time for the world economy if Postcapitalism is even half right. Pensions taxation seems a good place to try and start to move our financial institutions in a more sustainable direction.

Does this meet the definition of democracy?

24. April 2015 · Write a comment · Categories: Prediction

The result of the forthcoming General Election is not in much doubt it would seem. Eight different polling organisations’ latest polls are shown above, and the similarities between them are so much more striking than the differences. It appears that we will be going through the motions of a process which is to a large extent predetermined on 7 May. The election result is not where the uncertainty lies.

However, the day afterwards, when the general public no longer has any say in what happens, is still deeply uncertain. Although the parties have all let us have their manifestos, details about how they would behave in the event of a distribution of seats which seems to be largely already decided in most cases (presumably because the parties think we might vote differently if we knew) are very sketchy. Does this meet the definition of democracy, ie a system of government by the whole population? The Electoral Reform Society would say not. I would argue it does.

If the election result is largely as expected what would it tell us about the views of the electorate? I think it would tell us:

They don’t want austerity on the scale of 2010-12 again (which is one reason why the Conservatives and Liberal Democrats together don’t appear likely to get a majority);
They are not as obsessed with immigration policy as the two main parties think they are (which is why they seem prepared to vote for a range of different approaches to managing immigration with no approach commanding majority support);
They don’t want a referendum on whether to stay in the EU (which is why the Conservatives and UKIP together will not be able to get a majority); and
They don’t support the current student fees system and don’t believe it is indistinguishable from a graduate tax (which is another reason why the Liberal Democrats and Conservatives together seem unlikely to get a majority).

There are probably several other attitudes amongst the electorate that can equally well be divined in the negative in a similar way (the BBC summaries of the parties’ positions on a range of issues can be found here), but the point is that a finely balanced pattern of parties of the type we look likely to end up with does not represent an inability to make a decision. It does however represent a determination not to allow any single party to make decisions. That seems to meet a reasonable definition of democracy to me.

We know zero about 2015

10. January 2015 · Write a comment · Categories: Antifragility, Economics, Prediction

There have been a lot of predictions already for 2015. The Chartered Institute for Personnel and Development predicts employment in the UK increasing by half a million, GDP growth of 2.4% and earnings growth of between 1% and 2%, ie keeping its predictions reasonably close to what happened in 2014 and/or what the OBR, OECD and IMF are predicting. The annual FT economists’ survey resulted in an average conclusion amongst 90 economists that GDP growth would increase from 2.4% pa to 2.5% pa around election time and then on to 2.6% pa soon after. I could go on but I think you get the general idea – small changes around current economic statistics with a remarkable level of agreement amongst the experts. It’s enough to make you want to use these predictions to populate your models with, which is of course the general idea.

But before you get any idea that these people know more about 2015 than you do, consider what was being said about the oil price only 6 months ago in the Office for Budget Responsibility’s Fiscal sustainability report. Here is the graph:

Once again, there was a trend of projecting a price rather similar to the current one and a remarkable level of agreement amongst the experts. Here is what has actually happened subsequently:

Now I don’t want to pick on these forecasters in particular, after all the futures prices indicated that these views were the overwhelming consensus. But the oil price is a fundamental indicator in most economic models – Gavyn Davies details how the latest fall in oil prices has changed his economic forecasts here – with implications for inflation and GDP growth, and dependent upon predictions about many other areas of the political economy of the world which impact supply (eg OPEC activity, war in oil-producing areas) and demand (eg global economic activity). So an ability to see a big move in oil prices coming would seem to be a clear prerequisite for being able to make accurate economic forecasts. It seems equally clear that that ability does not exist.

Economic forecasts generally tell us that things are not going to change very much, which is fine as long as things are not changing very much but catastrophic over the short periods when they are. Despite the sensitivity testing that goes on in the background, most economic and business decisions are taken on the basis that things are not going to change very much. This puts most business leaders in the individualist camp described here, ie a philosophical position which encourages risk taking. Indeed even if some of the people advising business leaders are in the hierarchist camp, ie believing that the world is not predictable but manageable, to anyone with little mathematical education this is indistinguishable from an individualist position.

The early shots of the election campaign have so far been dominated by the Conservative Party branding Labour’s spending plans (which to the extent they are known appear to involve quite severe fiscal tightening, although not as drastically severe as Conservative ones) as likely to cause “chaos”, while the Labour Party wants to wrap itself in the supposed respectability of OBR endorsement of their economic policies. Neither of them has a plan for another economic crisis, which concerns me.

What are desperately needed are policies which are aimed at reducing our vulnerability to the sudden movements in economic variables which we never see coming. We should stop trying to predict them because we can’t. We should stop employing our brightest and best in positions which implicitly endorse the assumption that things won’t change very much because they will.

What sort of an economy would it have to be for us not to care about the oil price? That’s what we need to start thinking about.
