Is it possible to have sensible policy discussions about climate change?

 

Development of public policy depends to a large extent on sensible public discussion to filter out stupid proposals.  Climate change is no exception. The problem is that instead of having sensible discussions a lot of people just accuse one another of being deniers or alarmists, and use political stunts to advance or defend stupid policies.

It is easy to get the impression that most people can be classed as either deniers or alarmists, but surveys suggest to me that such extremists make up a relatively small proportion of the population of most countries. How many people get classified as deniers and alarmists is obviously influenced by the way these concepts are defined.

It makes sense to classify people as “deniers” if they claim climate change is “not a threat”. A survey by the Pew Research Center conducted in 2018 found that the percentages saying that climate change is not a threat vary substantially among the 26 countries included, from 21% in Nigeria to 3% in France and South Korea. Corresponding numbers were 16% in the U.S., 9% in Australia and 4% in Sweden.

The Pew survey found that in most countries a majority viewed climate change as “a major threat”, but it would be an exaggeration to label all those as alarmists. The people I describe as alarmists tend to say things like: “It is already too late to avoid the worst effects of climate change”. An international poll by YouGov, taken in 2019, found that people who say that vary from 20% of the population in France to 4% in Oman. Corresponding numbers were 10% in the U.S. and Australia, 8% in Sweden, 11% in Britain, and 6% in China.

False alarm

I was prompted to attempt to get a handle on the percentages of deniers and alarmists by my reading Bjorn Lomborg’s latest book, FalseAlarm: How climate change panic costs us trillions, hurts the poor, and fails to fix the planet. Lomborg sees climate change alarmism as a greater problem than denial. He suggests that the arguments of the deniers have been “thoroughly debunked” and approves of media refusing to give space to deniers. His main gripe is that media are “failing to hold climate alarmists to account for their exaggerated claims”.

However, it seems to me that different media outlets have different biases. Some pander to the prejudices of the noisy alarmists among their readers, while others pander to the noisy deniers. Unfortunately, the mass media no longer does much to promote sensible discussion of issues that have become politicized.

Lomborg’s book seems to me to advance a coherent viewpoint that could provide a basis for sensible discussion among people who are not wedded to extreme positions. His main points are as follows:

• Climate change is real. The amount of CO2 in the atmosphere affects global temperature.
• Global warming will have a negative impact on human well-being. Estimates of the likely damage from global warming by 2100 amount to a modest percentage of GDP (about 4%) if allowance is made for adaptation, fertilization (positive impacts of CO2 on crop yields and forest production) and the expanding bullseye effect (the tendency for more people to live in flood prone and fire prone areas).
• If all nations met their promises under the Paris Agreement, that would have only a small impact on global warming.
• With known technology and using the most efficient policy instrument to achieve Paris Agreement targets, the cost involved would be much higher (perhaps 3 times higher) than the expected benefits.
• There is potential for research and development to reduce the cost of green energy alternatives to use of fossil fuels. However, governments are not meeting the commitments they have made to expand relevant R&D activities.
• Carbon taxes and green energy innovation will not obviate the need for adaptation to a warmer climate over coming decades. Adaptation is a less costly option than attempting to reduce CO2 emissions to zero over the next few decades.
• Geo-engineering is worth researching as a backup plan to be used as required, e.g. if the West Antarctic ice sheet starts to melt precipitately.
• People in low-income countries will be better able to cope with the adverse impacts of climate change if they become wealthier. Holland and Bangladesh both have substantial areas of land below sea level, but Holland can afford infrastructure that enables it to cope better. 

 

My overall impression is that Lomborg has made a serious effort to focus discussion on things that are worth discussing. I have some reservations about his views, which I will mention below, but my initial focus is whether the book is generating useful discussion. I have found a couple of reviews by people who could be expected to challenge the argument that Lomborg advances.

Reviews

The first review is by Joseph Stiglitz, a Nobel prize winning economist. Stiglitz’s review was published in the New York Times. Rather than addressing the cost of current policies, Stiglitz appeals to an authority which he seems to view as infallible - an international panel chaired by himself and Lord Nicholas Stern – which apparently “concluded that those goals could be achieved at moderate cost”. I have not been able to find that conclusion in the report of his High-Level Commission, but I can’t claim to have read the document thoroughly. My brief reading left me with the impression that the costs will only be moderate if there is rapid progress in development of green technology. Stiglitz does not acknowledge that Lomborg advocates increased R&D for to promote more rapid development of green technology.

Stiglitz concludes by asserting:

“Lomborg’s work would be downright dangerous if it were to succeed in persuading anyone that there was merit in its arguments”.

Rather than engaging in sensible discussion, Stiglitz seems to me to be intent on using polemics to defend alarmism.

Surprisingly, there has been more sensible review in “The Guardian”. That review is by Bob Ward, who is associated with the Grantham Research Institute on Climate Change at the LSE. Ward combines his review of Lomborg’s book with a review of Michael Shellenberger’s book, Apocalypse Never. Ward’s remarks are somewhat offensive - he labels the authors as “lukewarmers”, promoting a “form of climate change denial”. Nevertheless, he manages to acknowledge that they make legitimate criticisms of alarmism by environmentalists. He agrees that the world should be investing more in helping poor people become more resilient to climate change. He also expresses sympathy for the view that nuclear power has a role to play in creating a zero-carbon energy system.

My reservations

The main problem I see with Lomborg’s argument relates to the use of GDP as a welfare measure. As well as the usual problems in the use of GDP in this way, there is the additional problem that many of the costs of adaptation are counted as making a positive contribution to GDP. For example, infrastructure investment to build walls to hold back rising sea levels is counted as part of GDP. As such adaptation investment comes to represent an increasing share of total investment, it will crowd out other investments that have potential to enhance human well-being.

This line of reasoning reinforces the importance of R&D that has potential to reduce the cost of alternative energy and hence to reduce the cost of mitigation. If it becomes less costly to pursue greater mitigation over the next few decades, that can obviously reduce the combined total of damage and adaptation costs over the longer term.

My other reservation relates to something that is not central to Lomborg’s argument, as outlined above, but is difficult to let pass. It is his endorsement of the proposition that “if everyone does a little, we’ll achieve only a little”. That seems to me to promote unwarranted pessimism about the likelihood of success of the polycentric approach promoted by Elinor Ostrom.

In a paper presented to the World Bank in 2009, Ostrom suggested that rather than wait for national governments to take concerted action, the best way forward was multi-layered action by individuals and firms, as well as by local, state, and national governments. The polycentric approach is messy, but there are hopeful signs emerging that it is developing sufficient momentum to facilitate effective action. The individual actions of environmentally conscious individuals may not add up to much by themselves, but they seem to be inducing an increasing number of firms to modify their behaviour. Some firms are presenting an environmentally friendly image without doing much to back it up, but others seem to be actively planning for a carbon-free future. The announcement last year by the world's largest asset management firm, BlackRock, that it will put climate change at the centre of its investment strategy, seems to me to signify a substantial change in the way the game is being played. If enough firms adopt R&D, innovation and investment strategies based on expectations of a carbon-free future, those expectations will tend to become self-fulfilling.

Bottom line

Lomborg’s book is not likely to persuade many climate change alarmists (or deniers) to modify their views, but it provides a basis for the rest of us to have sensible discussions about policy options.

Can any of the positive rights listed in the UDHR be considered natural rights?

A statement made last year by Michelle Bachelet, the UN High Commissioner for Human Rights, marking the 70^th anniversary of the Universal Declaration of Human Rights (UDHR) prompted me to take another look at it  In her statement, Ms Bachelet suggested that the UDHR has “withstood the tests of the passing years” and “has passed from being an aspirational treatise into a set of standards that has permeated virtually every area of international law”.

The UDHR is not a document that I look at often. My reason for largely neglecting the document has been the perception that it is aspirational, and involves a large element of wishful thinking. Ms Bachelet’s suggestion to the contrary reminded that Friedrich Hayek had asserted that by proclaiming social and economic aspirations to be rights, the UDHR was playing “an irresponsible game with the concept of ‘right’ which could result only in destroying the respect for it” (Law, Legislation and Liberty, p 105).

After re-reading the UDHR, there are a couple of points I would like to make about it.

First, Hayek was right!

Hayek’s warning about the confusion of the concept of right in the UDHR was appropriate. For example, consider Article 15:

“Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.”

Article 15 seems to tell everyone that the world owes them a living. But who will pay? Nature has different imperatives. Human flourishing depends on what people can do individually and collectively to help themselves and each other. Governments may help by defending the natural rights that enable people to better their own condition and help others. Although they often promise to ensure that everyone has an adequate standard of living, governments can’t themselves generate the wealth needed to keep such promises.

Governments can redistribute wealth, but their redistribution efforts tend to discourage wealth creation. What happens when redistribution is pushed too far is obvious from the recent experience of Venezuela. The policies followed by the Venezuelan government were presumably intended to contribute to the human flourishing aspirations underlying Article 15, but they have had the opposite effect of impoverishing many people in that country. The incoming Venezuelan representative on the UN human rights council would do us all a favour if he or she could acknowledge the consequences of the Venezuelan government’s efforts to comply with Article 15.

The UDHR would have provided a more coherent defence of human rights if its framers had given more attention to the insights of Frédéric Bastiat about natural rights and the role of law. In The Law, published in 1850, Bastiat makes the point that everyone has a natural right to defend their person, their liberty and their property, and asserts that the law should be viewed as “the collective organization of the individual right to lawful defense”:

“When law and force keep a person within the bounds of justice, they impose nothing but a mere negation. They oblige him only to abstain from harming others. They violate neither his personality, his liberty, nor his property. They safeguard all of these. They are defensive; they defend equally the rights of all”.

Second, some of the positive rights in the UDHR are worth supporting.

I am referring to various legal rights relating to natural justice, or procedural fairness, and the right of political participation in Article 21:

“Everyone has the right to take part in the government of his country, directly or through freely chosen representatives”.

People who live in liberal democracies tend to take that right that for granted, and many are even disillusioned about it, but it is a right that people seek persistently when it is denied to them. Tyrants understand that well; although they often claim to be adored by citizens, they are rarely willing to allow their popularity to be fairly tested in fair elections. The recent protests in Hong Kong show that the right to political participation is keenly sought even when people live under a regime that, for the time being, provides individuals with greater economic freedom than is enjoyed in most liberal democracies.

Friedrich Hayek argued in favour of recognition of such political rights in the following terms:

“Since we are all made to support the organization of government, we have by the principles determining that organization certain rights which are commonly called political rights. The existence of the compulsory organization of government and its rules of organization does create a claim in justice to shares in the services of government, and may even justify a claim for an equal share in determining what government shall do” (LLL, p 102).

Is political participation a natural right?

It seems to me that the right to political participation should be viewed as a natural right for much the same reasons as I have argued that humans have a natural right to exercise the self-direction that is central to their flourishing. It is part of human nature to seek mutual benefit by participating actively with others in decisions relating to provision of collective goods because provision of such goods is, and has always been, necessary to human flourishing. As Aristotle said, “man is by nature a political animal”.

The context in which Aristotle made that observation is worth quoting because what he described seems to an essentially voluntary process of people coming together for mutual benefit:

“When several villages are united in a single complete community, large enough to be nearly or quite self-sufficing, the state comes into existence, originating in the bare needs of life, and continuing in existence for the sake of a good life. And therefore, if the earlier forms of society are natural, so is the state, for it is the end of them, and the nature of a thing is its end. For what each thing is when fully developed, we call its nature, whether we are speaking of a man, a horse, or a family. Besides, the final cause and end of a thing is the best, and to be self-sufficing is the end and the best.

Hence it is evident that the state is a creation of nature, and that man is by nature a political animal” (Politics, Book 1, Part 2).

The political participation of a citizen in a liberal democracy, which usually doesn’t involve much more than voting, has little in common with the participation of citizens in the functioning of the city states that Aristotle wrote about. Perhaps that helps to explain the disillusionment that many currently feel about the exercise of their democratic rights. Responses to surveys suggest that many people want more involvement in decisions that affect them.

Many people are also unhappy about the outcomes of democratic political processes. In my view that unhappiness stems to an important extent from inflated expectations generated by UDHR and other authorities which assert that people have the right to expect politicians to deliver them a standard of living they consider to be adequate. Another important source of disillusionment is the ‘plunder’ that Frédéric Bastiat foresaw as a likely outcome of the universal franchise. Bastiat was referring to the use of the power of the state by some to seize and consume the products of the labour of others. These days economists refer to that as rent seeking and usually consider it to be a major obstacle to productivity growth.

It seems likely in the decades ahead, that low productivity growth will reduce the rate of growth in government revenues in many democratic countries, at the same time as an increase in the proportion of elderly people places increased political demands on governments. Consequently, governments are likely to be forced to reduce their involvement in provision of services that can be supplied either privately, or via voluntary cooperative activity.

Fortunately, as I have previously discussed, technology is developing in ways that are likely to enhance our opportunities to seek mutual benefit in cooperative enterprises.

Conclusions

The right to political participation should be viewed as a natural right which evolved because human flourishing required individuals to participate actively with others in decisions relating to provision of collective goods. Such involvement is less active in modern societies in which many collective goods are provided by remote government agencies.

The positive right to political participation is nevertheless an important right recognised in the UDHR. It differs from social and economic aspirations - that are also claimed to be rights in the UDHR - because it is a right that governments can comply with. The exercise of voting rights provides citizens with some protection against tyranny.

The disillusionment that many people in the liberal democracies feel about the exercise of their democratic rights seems likely to increase as low productivity growth reduces government revenues and demographic change increases political demands on governments. Technological advances that enhance opportunities to seek mutual benefit in cooperative enterprises offer hope that people will in future be able to exercise their natural political rights in ways that give them more involvement in decisions that affect them.

How can we compare climate change and public debt risks?

It seems to me that, over the next 20 years or so, people in Western democracies are likely to suffer to a greater extent from the consequences of an explosion in public debt than from climate change. At the same time, I acknowledge that climate change could possibly pose a serious threat to civilization and perhaps human survival. The chart shown above is my attempt to illustrate how those risks might be compared.

I make no claim to expertise in assessment of climate change risks. My reading on the topic suggests that the theory that increasing concentrations of greenhouse gases in the atmosphere are contributing to climate change is widely accepted by scientists. However, people with relevant expertise obviously have different views about the rate at which climate change is likely to occur, the contribution of human activity, the political feasibility of various forms of remedial action, and the adaptability of humans and other living creatures.

In my view, too little attention has been given to “tail risk” associated with climate change – the low probability that climate change will result in a great deal of human misery, as shown in the chart above. As I have written here previously, if you are concerned about climate change, you (like me) are likely to be more concerned about the remote possibility that your great grandchildren might suffer from having to live with potentially catastrophic climate change outcomes than about the more probable outcome that climate change might cause their incomes to be somewhat lower than economic modelling suggests they would be otherwise. I have also previously expressed agreement with Nassim Taleb that there are some risks we should avoid if possible, even though there is a low probability that they will occur at any point in time. In order to flourish, future generations need to be able to survive.

The reasoning behind the rest of the chart requires more explanation. Why do I think there is a 95% probability that the citizens of western democracies will suffer as much or more over the next 20 years from an explosion in public debt than from climate change? Since I don’t have either the inclination or expertise to weigh up the technical evidence on climate change for myself, I tend to rely on the IPCC’s assessments. I suspect the authors of IPCC reports are still somewhat biased toward attempting to present a view favouring urgent international action to reduce greenhouse gas emissions. Nevertheless, after they have been modified in the light of expert public scrutiny, the IPCC reports are probably the most authoritative source of independent assessments of the relevant evidence.

The IPCC’s assessment of likely climate change outcomes in Chapter 3 of its recent special report, Global Warming of 1.5 ºC, implies that we can expect some fairly serious adverse consequences over the next few decades:

“The impacts of climate change are being felt in every inhabited continent and in the oceans. However, they are not spread uniformly across the globe, and different parts of the world experience impacts differently. An average warming of 1.5°C across the whole globe raises the risk of heatwaves and heavy rainfall events, amongst many other potential impacts. Limiting warming to 1.5°C rather than 2°C can help reduce these risks, but the impacts the world experiences will depend on the specific greenhouse gas emissions ‘pathway’ taken. The consequences of temporarily overshooting 1.5°C of warming and returning to this level later in the century, for example, could be larger than if temperature stabilizes below 1.5°C. The size and duration of an overshoot will also affect future impacts.”

However, a recent OECD report on Greece, which is fairly optimistic about the future of that economy, seems to me to illustrate that public debt crises are likely to result in much more human misery than climate change over the next few decades:

“Despite these positive developments, challenges abound. GDP per capita is still 25% below its pre-crisis level. The public debt is still high and a source of significant vulnerability. Poverty rose sharply during the crisis, especially among the young and families with children. Though poverty has stabilised, it remains near a record high. Skill mismatch is also high and investment remains depressed. This contributes to low productivity – which has fallen further behind other OECD countries – and low wages – resulting in high in-work poverty. Though improving, female labour participation is among the lowest across OECD countries. The recovery in investment is held back by a dearth of finance – due in part to high levels of non-performing loans and to capital controls – high cost of capital relative to wages, cumbersome regulations and low demand. These problems weigh on people’s well-being”. 

As I explained in a recent post, there are strong reasons to expect that the failure of governments in most OECD countries to restrain the growth of government spending is likely to cause debt servicing to become a more widespread problem in the decades ahead.  I think the most likely outcomes in most western democracies will probably be much worse that the outcomes of climate change, although not be as bad as the experience of Greece over the last decade. The chart above is drawn to acknowledge that there is some possibility that democratic governments will lift their performance, or world interest rates will remain low, so debt servicing may not be a problem.

The modest adverse outcomes depicted on the right side of the chart might well be offset by positive factors. There is a good chance that over the longer term the positive impacts of technological advances will be sufficient to offset the negative impacts of both public debt accumulation and climate change, but it would be excessively optimistic to expect rapid technological progress and productivity growth in western democracies over the next 20 years.

Some readers may object to my attempt to compare the risks associated with climate change and public debt explosion on the ground that these are very different risks when viewed at a national public policy perspective. There obviously isn’t much the government of any country can do to reduce climate change risk by acting alone.

However, I have drawn the chart with individual well-being in mind. From an individual’s perspective, the risks surrounding climate change and public debt are quite similar. Nothing that individuals do by themselves will make much difference to national or global outcomes. Voting might appear to provide an avenue for individuals to influence national outcomes but, as others have observed, voting in a national election is like ordering a meal from the menu in a restaurant and being served the same meal irrespective of what you order.  

There are options that individuals can consider to reduce their exposure to both climate change and public debt risks. For example, consideration of climate change risk might influence decisions about housing location and construction, and consideration of public debt risks might cause individuals to reduce the extent that their families rely on government for health services, education and retirement incomes.

It strikes me that climate change and the risks of public debt explosion also pose similar ethical issues for individuals. Does the fact that an individual’s actions, considered in isolation, has a negligible impact on global and national problems absolve him or her of an obligation to moderate his or her contributions to those problems? I think not, but I will leave consideration of the issue for another time.  

Where did I go wrong in writing about the greatest threat to human flourishing?

Chapter 8 of my book Free to Flourish, published in 2012, is entitled “The Greatest Threat to Progress”.

The concluding paragraph of that chapter now seems like an exercise in wishful thinking:

“There is an urgent need for innovations to promote a better balance between the responsibilities and effectiveness of government. The best hope is that, as more people perceive the threats that democracy is facing, they will unite to foster the development of better norms of political behaviour."

Do you perceive that a growing proportion of voters in your nation are using politics opportunistically to obtain benefits for themselves at the expense of others? If so, do you perceive that such behaviour is a threat to the democratic political system? Are you willing to commit to promoting mutual benefits for all citizens in your participation in political discussions and in casting your vote?

If you answered “yes” to all those questions, how much time and energy are you prepared to invest in encouraging others to unite with you in fostering restoration of better norms of political behaviour?

I still think it is commendable for individuals to foster better norms of political behaviour, for example in their activities on social media. However, the idea that citizens might unite to restore better norms of political behaviour now seems excessively optimistic.

Where did I go wrong?

I haven’t changed my view that the failure of democratic governments to cope with their expanding responsibilities is the greatest threat to human progress – the ongoing expansion of opportunities for human flourishing - in coming decades. Democratic failure seems likely to be particularly traumatic for people who have become heavily dependent on government.

My analysis in Chapter 8 of what determines whether democracies can cope still looks sound. The democratic governments that are highly effective in raising revenue and managing provision of services with little corruption (e.g. Sweden) are able to cope with greater responsibilities than can governments that are less effective in performing those functions (e.g. Greece). The ability of democratic governments to cope depends on the balance between responsibilities and effectiveness.

It still seems correct to argue that there is an inherent tendency in democracies for the size of government to expand and for the effectiveness of government to falter. That is a natural consequence of unrestrained politicking by interest groups.

I still think Joseph Schumpeter and Bryan Caplan were correct to argue that citizens are prone to irrational prejudice in political matters. My empirical work helps illustrate the nature of the problem. It shows that the percentage people who seek an expanded role for government is higher among citizens who claim to have little confidence in the civil service and no interest in politics.

My argument that democracy has survived because it has been constrained by constitutions, rule of law and federal systems of government still looks ok. If writing the chapter now I would also emphasise that norms of reciprocity have helped to restrain interest group opportunism in the past.

I think my discussion of changes in democracy brought about by increased citizen involvement through talk shows, social media etc reached the correct conclusion. The changing political environment seems to have provided greater incentives for political parties to become involved in identity politics, and to seen to be doing more to deal with all the problems of modern life:

"The realm of personal responsibility has shrunk as more personal problems have become transformed into social problems. The net result in most high income countries has been an aggravation of the tendency for governments to take on more responsibilities than they can cope with effectively. Yet governments are constantly pressured and tempted to accept additional responsibilities."

That quote from Free to Flourish is followed immediately by the heading: “A basis for hope”. That is the section in which I made a valiant attempt to persuade myself that citizens might unite to foster the development of better norms of political behaviour.

There was nothing wrong with looking for a basis for hope. In retrospect, I was just looking in the wrong place.

Developments over the last few years suggest that there is a basis for hope in two different directions.

First, it looks to me as though the consequences of democratic failure might not be quite as dire as I had envisaged in 2012. At that time it seemed to me as though democratic institutions were coming under threat in some countries of southern Europe because of increased public disorder associated with government debt crises and resistance to government spending restraint. I was concerned about democratic governments being replaced by authoritarian regimes, as has occurred under similar in the past in Europe and Latin America.

What has happened is that democratically elected leaders have remained in place to administer the austerity that was imposed by the European Central Bank. The failure of democratically elected governments to control government spending resulted in external imposition of constraints on fiscal policy. This has been accompanied by a great deal of economic misery in the countries affected, but outcomes have been better than I had expected.  

As discussed in a recent post, I expect that in most OECD countries the failure of democratic governments to restrain the growth of government spending is likely to cause debt servicing to become a more widespread problem in the decades ahead. Perhaps there are grounds for hope that when they see the writing on the wall, a sufficient proportion of voters in most wealthy countries will be supportive of political parties proposing economic reforms, rather than waiting until they are imposed by creditors (or institutions such as the ECB and IMF).

Second, there is now a stronger basis for hope that the faltering institutions of representative government could one day be replaced by superior institutions. I was sceptical about that possibility at the time of writing Free to Flourish. Since then, however, it has become evident that blockchain technology and smart contracts may have potential to enable people to act together to produce some public goods cooperatively without central government involvement. I became enthusiastic about the potential for that to occur a few months ago when reading The Social Singularity, by Max Borders.  I have learned a little more about blockchain and smart contracts since then, and am still enthusiastic about the potential it offers.

A transition from government to cooperative provision of services cannot be expected to prevent the human misery likely to occur as a result of failure to constrain government spending before debt servicing problems become acute. Over the longer term, however, it may become possible for people to enter voluntarily into real social contracts that offer better opportunities for human flourishing than the hypothetical social contracts of political theory.

Perhaps it would have been better for Chapter 8 of Free to Flourish to have concluded by focusing on ways in which individuals might be able to protect themselves and their families from the consequences of democratic failure.

The most obvious way for people to protect themselves and their families is to avoid becoming heavily dependent on government. I acknowledge that for many people that is easier said than done. Few people choose to become heavily dependent on government. Hopefully, safety nets will continue to be available for those who need them most.  Nevertheless, self-reliance and voluntary cooperation for mutual benefit will provide most individuals the best hope for economic security in the years ahead.

Which of the western democracies will be able to cope with future growth in government health spending?

The chart shows that those OECD countries with the greatest burden of debt servicing a decade ago have subsequently had the lowest growth in government spending. It isn’t hard to understand how that might happen when we think about the consequences of accumulating debt in our personal lives. If we go heavily into debt, a higher proportion of our income must be devoted to servicing debt and less is available for other spending. Our creditors are likely to be reluctant to extend further credit if they become concerned about our ability to service existing debt.

At a national level, there are additional complications including the potential for governments to inflate away the real value of debt denominated in local currency and possible ‘bailouts’ by the IMF and ECU. Nevertheless, governments that become poor credit risks must pay a higher risk premium than is normal for government bonds, in order to obtain access to additional credit.

There is evidence that rising government debt to GDP ratios are associated with lower economic growth, which in turn, leads to lower growth in government revenue. That obviously has potential to further squeeze non-interest government spending. The results of a recent study published by the Dallas Fed (‘Rising Public Debt to GDP Can Harm Economic Growth’, by Alexander Chudik, Kamiar Mohaddes, M. Hashem Pesaran and Mehdi Raissi) suggest that over the longer term persistent accumulation in debt as a percentage of GDP at an annual rate of 3 percent is eventually associated with annual GDP growth outcomes that are 0.2 to 0.3 percentage points lower on average. To put that in perspective, the average growth rate of OECD countries has been about 1.5 percent per annum over the last decade. Causality could run both ways. Lower GDP growth can lead to higher debt levels, which, in turn, can lead to lower economic growth.

You might be wondering why I think the chart shown above has much relevance for western democracies other than Greece, Italy and Portugal, which had high government debt servicing burdens a decade ago. The relevance stems partly from the continued increase in government debt as a percentage of GDP in most OECD countries over the last decade. On average, net financial liabilities of those countries have risen by around 23 percentage points of GDP over the last decade to around 67% of GDP in 2018.

Those looking for reasons to be complacent can obtain some reassurance from low world interest rates. With interest rates paid by governments lower than the rate of economic growth in most OECD countries, debt servicing is not yet a widespread problem. At current interest rates, it would be possible for the debt to GDP ratio to decline in most OECD countries, even if governments pay interest on their debts by borrowing additional funds.

How likely is it that world interest rates will remain at low levels over the next few decades? In their recent OECD paper, The Long View: Scenarios for the World Economy to 2060, Yvan Guillemette and David Turner suggest that relatively low growth in investment is likely to keep downward pressure on world interest rates, even though population ageing is likely to reduce savings rates. Nevertheless, they note evidence that reversals of the relationship between world interest rates and economic growth rates have been “fairly common” in the past. They warn that a sustained rise in interest rates relative to growth “could eventually make large debt stocks costly to service and unsustainable”.  Their projections suggest that some decline in economic growth rates is likely to occur in most parts of the world over the next 40 years.

My concerns about the potential for debt stocks to become costly to service in many more OECD countries are related to the implications for government spending of the ongoing increase in the proportion of elderly people in the populations of these countries. The implications of demographic change have been much talked about over the last few years, but the magnitude of the likely impact on government spending doesn’t yet seem to be widely appreciated. The study by Guillemette and Turner projects an increase in annual public health and pension spending of about 5 percentage points of GDP for the median OECD country between 2018 and 2060. The bulk of that increase is for public health spending, which is projected to continue to be pushed up by technological change and government health policies, as well as demographic factors.

The methodology used by Guillemette and Turner produces estimates of the increase in the revenue to GDP ratio needed to pay for projected government spending increases without any further increase in debt to GDP ratios. An increase in revenue as a percentage of GDP of 6.5 percentage points of GDP is projected to be required for the median OECD country over the period to 2060. A much larger increase is projected to be required in some countries. For example, the required increase in revenue for the U.S. is projected to be 10 percentage points of GDP.

I think the baseline scenario presented by Guillemette and Turner is too optimistic because their modelling takes no account of the disincentive effects of higher taxation on GDP growth. The possible magnitude of this excess burden of taxation is discussed in an Australian context in an article posted on this blog a few years ago.

Leaving that aside, it seems to me that ongoing increases in debt to GDP ratios - and hence substantial increases in government interest payments as a percentage of GDP - are a much more likely outcome in most OECD countries than tax increases in the years ahead. In those countries where debt servicing isn’t yet a problem, there seems likely to be much less political opposition to further increases in public debt than to tax increases. That suggests to me that over the next few decades most OECD countries are likely to increase their debt to GDP ratios until debt servicing does become a more widespread problem.

Guillemette and Turner present scenarios that would require smaller increases in government revenues than in the baseline (no-change) policy scenario, but those scenarios involve health policy and labour market reforms that have been difficult to achieve in the past. I don’t think we can expect voters to be any more supportive of reforms that could damage their short-term interests than they have been in the past. The best we can hope for is that when they see the writing on the wall, a sufficient proportion of voters in most countries will be supportive of political parties proposing economic reforms, rather than waiting until they are imposed by creditors (or institutions such as the ECB and IMF). In 2013 I wrote something here contrasting the responses of Sweden and Greece to fiscal crises, that illustrates the choices available.

The transition may be traumatic, but it seems likely that technological advances will provide options superior to government provision of many services in coming decades. What I have in mind particularly is the potential for blockchain to enhance opportunities to seek mutual benefit in voluntary cooperative enterprises, as previously discussed on this blog. That may create potential for functions to be transferred from the public sector to cooperative enterprises that can perform the functions more efficiently.

During the next few decades most of the western democracies seem likely to experience ongoing difficulty in coping with the additional government spending required to meet the health needs of the elderly.  The most likely outcome seems to me to be an increase in debt to GDP ratios that will result in more widespread debt servicing problems. It seems inevitable that debt servicing problems will lead to a lower rate of growth in government spending in many OECD countries, possibly accompanied by the transfer of some functions to voluntary cooperative enterprises.

That leaves the difficult question of identifying which of the western democracies are more likely to be able to implement those reforms through normal democratic processes in order to avoid having austerity imposed upon them by creditors and international agencies.

Why don't all sides of politics agree to pursue Wealth Plus?

It would be great if the major political parties in all countries of the world were to pursue Wealth Plus as a national objective. However, I don’t think that is likely to happen soon, even in the wealthy countries that have implicitly pursued similar objectives in the past.

Wealth Plus is the objective advocated by Tyler Cowan, in his recently published book, Stubborn Attachments: A vision for a society of free, prosperous, and responsible individuals. Tyler defines Wealth Plus as:

‘The total amount of value produced over a certain time period. This includes the traditional measures of economic value found in GDP statistics, but also includes measures of leisure time, household production, and environmental amenities, as summed up in a relevant measure of wealth."

Tyler also suggests that we should aim to “maximize the rate of sustainable economic growth, defined in terms of a concept such as Wealth Plus”. He suggests that we should think more broadly about economic growth as an ongoing self-sustaining process that produces goods that contribute to human welfare, rather than in terms of growth in GDP as conventionally measured.

I think the objective that Tyler is writing about could better be described in terms of pursuing growth in opportunities for human flourishing – growing opportunities for people to live the lives that they aspire to have. I prefer that terminology partly because it fits neatly with the view I expressed in Free to Flourish that good societies are characterised by widespread opportunities for human flourishing. In my view, progress is movement toward better societies, with growing opportunities for human flourishing.

An emphasis on human flourishing raises a question, touched on in an appendix, of why human flourishing should be prioritized above the flourishing of non-human lives. One good reason is that flourishing humans show greater consideration for non-human lives than do humans who are struggling to survive. Discussion about what constitutes ethical behaviour toward non-human lives is a feature of modern life in prosperous countries. More fundamentally, if ethical behaviour is intrinsic to human flourishing – as Aristotle argued persuasively long before modern psychologists took up the idea - then human flourishing must encompass ethical behaviour toward all other living creatures.

Tyler makes a strong case that we should care about the well-being of people in the distant future just about as much as we care about the well-being of the current generation. His argument is based partly around the implications of discounting the value of future human lives. Under any positive discount rate, one life today could appear to be worth as much as the entire subsequent survival of humanity if we use a long enough time horizon for the calculation.

The argument for using a low discount rate seems to me to have considerable force when we are considering the benefits of public investments to protect future generations from potential catastrophes. As previously discussed on this blog, that argument is pertinent in considering what discount rates should be used for public investments to avert or mitigate climate change risks.

I am not persuaded by Tyler’s argument that the well-being of future generations isn’t adequately considered today in the choices “we” are making about “how rapidly to boost future wealth”. The “we” Tyler is referring to is the collective “we” that makes public policy choices. As I have previously suggested, the argument that positive externalities cause free markets to produce too little economic growth does not appear to have any more merit than the argument that negative externalities cause free markets to produce too much economic growth. Tyler hasn’t persuaded me that government intervention can improve on the growth outcomes of the savings and investment decisions made by individuals and families in a free market.  

In any case, the choices that governments make about “how rapidly to boost future growth” seem to be largely implicit rather than explicit. Boosting economic growth may be a motive for public investment in research and some forms of education, but I can’t think of many other examples. Perhaps what Tyler has in mind are the choices that governments make that unintentionally reduce the rate of economic growth. For example, he notes that when government spending is cut, investment spending is often the first area to go while entitlements for the elderly remain intact.

Tyler is on firm ground in arguing that the strengthening of good institutions today can be expected to provide benefits for centuries into the future. There is strong historical support for the view that growth promoting institutions and a history of prosperity tend to have enduring effects.

Tyler suggests that three key questions should be elevated in their political and philosophical importance, namely:

1.       What can we do to boost the rate of economic growth?

2.       What can we do to make our civilization more stable?

3.       How should we deal with environmental problems?

He goes on to observe:

“The first of these is commonly considered a right-wing or libertarian concern, the second a conservative preoccupation, and the third, especially in the United States, is most commonly associated with left-wing perspectives. Yet these questions should be central, rather than peripheral, to every political body. We can see right away how the political spectrum must be reshaped to adequately address these concerns. Politics should be about finding the best means to achieve these ends, rather than disputing the importance of these ends."

I agree that is what politics should about, but I am not optimistic that political leaders can pursue those ends diligently, even if they can be persuaded to embrace them. Liberal democracy has been weakened in recent decades by widespread failure to adhere to the norms of self-reliance and reciprocity that underpin it. As predicted by James Buchanan (see this post for explanation) failure of the liberal democracy is becoming increasingly likely as a higher proportion of the population becomes dependent on government, and voters increasingly seek to use the political process to obtain benefits at the expense of others.  

It is difficult to escape the conclusion that we are heading toward a tragedy of democracy. When interest groups view the coercive power of the state as a common pool resource to be used for the benefits of their members, the adverse impact of tax and regulation on incentives for productive activity produce outcomes that a detrimental to just about everyone. The process seems to be intensifying with the fragmentation of broad interest groups supporting the centre left and centre right of politics.

As Henry Ergas has noted recently, with particular reference to Australia, it has become “increasingly difficult for “catch-all” parties — as both our main parties have been — to position themselves in such a way as to aggregate a winning coalition. The concept of the ‘average’ or ‘median’ voter, which used to help orient the parties’ choices, has lost its substance, as has the notion of ‘the centre’. (“The Australian”, 25 Oct. 2018).

Similar problems are evident in other mature democracies. The process of fragmentation of broad interest groups has accelerated in many countries over the last decade or so as innovations in the social media have greatly increased the power of the rabid sports fans of politics - aptly referred to by Jason Brennan as Hooligans. Hooligans tend to seek out information that confirms their pre-existing political opinions and ignore or reject information that contradicts those opinions. They tend to communicate in echo chambers that reinforce their outrage when the leadership of the major parties is unresponsive to their concerns.

In some countries we are seeing ill-informed Hooligans taking over major parties and the reins of government. In other countries splinter parties comprised of Hooligans are attracting supporters away from major parties and making it more difficult for them to pursue coherent policy agendas. No matter which way it is happening, the growing political influence of the Hooligans makes it increasingly difficult for political leaders to pursue Wealth Plus, or any goals relating to the future well-being of the broader communities who elect them.

As more people come to recognize that liberal democracy is confronted by deep problems, perhaps some of them will attempt to make concerted efforts to reform political institutions so that they produce better outcomes. However, it is not obvious what reforms would stop the rot or how reforms could be achieved. A major economic crisis might help to focus the minds of responsible political leaders, but it could just as easily further strengthen the hands of the Hooligans.

I now think the best hope for future generations lies in the potential for new technology to enable people to circumvent the obstacles created by the Hooligans of national politics. As Max Borders has suggested (see discussion on this blog here and here) technological innovations provide us with the potential to “reweave the latticework of human interaction to create a great reconciliation between private interest and community good". The social singularity has potential to enable people to enjoy growing opportunities to live the lives that they aspire to have.

Should we look forward to the Social Singularity?

The social singularity should not be confused with the technological singularity, which Wikipedia defines as the hypothesis that invention of artificial superintelligence will abruptly trigger runaway technological growth, resulting in unfathomable change to human civilization.

The Social Singularity, as described by Max Borders in his recently published book of that name, relates to the way we (humans) organise ourselves in relation to each other. Max’s hypothesis is that at some point social organisation will be completely transformed as a result of mass adoption of secure networking technologies. When that happens some existing mediating structures will become obsolete, new forms of coordination will emerge and we will collaborate as never before.

What does that mean in terms that you and I can understand? The best place to begin is with the concept of subversive innovation. You might think it is tedious to begin an explanation by introducing another concept, but I promise to provide some concrete examples before long.

These days just about everyone knows what an innovation is. Most readers will be familiar with disruptive innovations that are making many goods more accessible and affordable. Subversive innovations “are those that have the potential to replace long-accepted mediating structures of society”. The mediating structures that Max is writing about include: hierarchical firms; group-think practices among the scientific establishment that have led to widespread acceptance of numerous findings that cannot be replicated; centralised education which views students as having “heads like buckets to be filled with information curated by central elites”; long-standing practices of financial intermediaries; mainstream media that once generated social coherence; and national governments.

Readers will already be familiar with some of the subversive innovations that are occurring. Some firms are replacing hierarchical command and control structures with decentralised systems in which self-directed individuals create order by establishing networks to achieve common purposes. The Internet has enabled informal networks of people, often including amateurs, who question scientific dogma e.g. the paleo-diet movement. Disruptive innovation has begun in primary, secondary and tertiary education. Long-established practices of financial institutions are being challenged by block chain technologies, and cryptocurrencies are enabling people to transact without using national currencies or financial intermediaries. The Internet has disrupted the role of mainstream media in generating social coherence - making it possible for populists to challenge political orthodoxy, but also reducing the potential for views to coalesce around a deeply flawed narrative.

The potential for subversive innovations to displace centralised government is in my view the most interesting idea in the book. We can already see this happening to some extent as innovating firms search out the weak joints in government regulation, particularly the regulatory barriers to competition that have enabled incumbents in various industries to prosper at the expense of the rest of the community. Think of how Uber’s ridesharing innovations circumvented regulations protecting incumbents in the taxi industry.

Max suggests that the potential for subversive innovations to displace centralised government will be enhanced by the advent of smart contracts in which a host of humans can act together to achieve a common goal without middlemen. The coordinating mechanism of smart contracts involves distributed ledgers, programmable incentives and blockchain secured tokens. Tokens can align the interests of producers, consumers and investors in ways that may have potential to enable many types of public goods to be produced privately by profit-seeking entrepreneurs. It doesn’t seem possible at this stage to provide a concrete example of how this might work. Perhaps it can be thought of as crowdsourcing on steroids.

Where might this take us? Max suggests that the potential for people to forge real social contracts - contracts they choose to enter voluntarily rather than the hypothetical social contracts of political theory - “could become the killer app of politics”:

"Communities of tomorrow will form entire systems of mutual aid through digital compacts that have nothing to do with borders or accidents of birth. … Humanity will upload important commitments into social contracts. Cosmopolitan communities of practice will form in the electronic ether. What remains on the ground—goods, services, and the relationships of flesh-and-blood neighbors—will be a far more localized phenomenon. The days of outsourcing our civic responsibilities to distant capitals are numbered."

What Max has in mind is polyarchy – competitive provision of goods that have been provided collectively. The basic idea is that if there is nothing intrinsically territorial about a system that provides goods like health insurance or education, you should be allowed to exit one system and join another without moving to a different system’s territory. You could take resources you were once required to pay in taxation and use them to pay for membership of another community or multiple other communities.

So, what reason do we have to think that governments might one day be willing to recognize the right of exit required to make polyarchy a reality?

Max notes that new constituencies are forming around the benefits of the sharing economy:

"Special interests that once squeaked to get the oil are confronted by battalions bearing smartphones. Citizens, fed up with leaving their prayers in the voting booth, are voting more with their dollars and their devices. Free association is now ensured by design, not by statute."

The Social Singularity mixes the author’s views on how things ought to evolve and how he expects them to evolve. Max acknowledges that he does this. The book offers readers an appealing vision of how the future could evolve and invites them to help make that vision a reality.

The book contains much that I haven’t written about in this short review. I should mention the link between the social singularity and spiral dynamics. Now I have mentioned it, I want to write more about it. Perhaps later!

I should also note before concluding that the title of the book, as presented on the title page, is The Social Singularity: A Decentralist Manifesto. Decentralization is a theme of the book. Max begins his chapter on the future of governance by quoting Vincent Ostrom:

“The fashioning of a truly free world depends on building fundamental infrastructures that enable different peoples to become self-governing”.

 In a post I wrote a few months ago I mused about how Ostrom’s vision of decentralisation of politics could eventually become a reality. If I ever write on that topic again there will be a reference to Max Borders and the concept of subversive innovations will feature prominently.

The Social Singularity deserves to be read widely and thought about deeply.

How many Hobbits and Hooligans would accept impartial expert advice about how to vote?

According to Jason Brennan, a political philosopher, there are three broad types of democratic citizen:

·         Hobbits are mostly apathetic and ignorant about politics. They don’t give politics much thought.

·         Hooligans are the rabid sports fans of politics. They have strong and largely fixed world views. They tend to seek out information that confirms their pre-existing political opinions and ignore or reject information that contradicts those opinions.

·         Vulcans think scientifically and dispassionately about politics. Their opinions are strongly grounded in social science and philosophy. They try to avoid being biased in explaining contrary points of view.

When I attempt to relate these citizen types to the stages of adult development identified by Robert Kegan and Lisa Lahey, discussed in my last post, it is obvious that Vulcans have self-transforming minds. I have the impression that other types of democratic citizen tend to exhibit lower stages of adult development in their political views than in other aspects of their lives. There isn’t much incentive to behave like a responsible adult in the political arena since your vote is unlikely to be decisive. Some Hooligans may be self-authoring (self-directed) in the sense that they have chosen for themselves which political team to support. In their role as citizens, however, Hooligans are characterised as having the socialized minds of faithful followers. Hobbits may be socialised, or even self-authoring, in some aspects of their lives, but they are disassociated from politics.  

In his book, Against Democracy, Jason suggests that few citizens are Vulcans. Nearly all citizens are either Hobbits or Hooligans. Hooligans have more political knowledge than Hobbits but are still prone to make systemic mistakes on many important issues in economics and political science. The cumulative impact of their incompetence has adverse consequences for other citizens. On this basis Jason argues that there are good grounds to presume that some feasible form of epistocracy – a system that gives competent and knowledgeable citizens more political power than others - would out-perform democracy, in which all citizens have equal voting rights. Epistocracy would still result in rule by Hooligans, but would give greater power to competent and knowledgeable Hooligans.

Jason is against democracy only in the sense that he considers that some form of epistocracy would be likely to produce superior outcomes. He acknowledges evidence that democracies have done a better job of protecting economic and civil liberties and well-being of citizens than dictatorships, one-party governments, oligarchies and real monarchies.

In the light of the bias and ignorance of voters, some readers may be wondering how most modern democracies have managed to avoid catastrophic outcomes. Jason suggests that has been prevented by several moderating factors including the power of the judiciary and government bureaucracies to set their own agenda, the power of political parties to shape the political agenda independently of what voters desire, and politicians who have generally been much better informed than voters.

That line of reasoning supports the views of Joseph Schumpeter, a famous economist who argued about 70 years ago that the success of democracy was problematic unless it was strictly limited.  In my book Free to Flourish I noted that other famous economists, including James Buchanan and Milton Friedman, suggested that additional constraints needed to be imposed on democratic politics to avoid bad outcomes.  

In the preface to the 2017 paperback edition of Against Democracy, Jason notes that in recent years more people have become willing to consider the flaws in democracy. After mentioning Trump and Brexit he goes on to make the point that his criticisms of democracy are based on information on voter ignorance that has been known for a long time. Unfortunately, he doesn’t explore whether there has been a change in the moderating factors that have hitherto ensured that outcomes are better than they would have been if the prejudices of ignorant voters had prevailed.

The change I have in mind is the declining power of the major political parties to shape political agendas in ways that moderate the ill-informed desires of electors. It strikes me that over the last decade or so, innovations in the social media have greatly increased the power of ill-informed Hooligans and the populist politicians who promise to give effect to their views. Ill-informed Hooligans can now more easily establish links with like-minded people who share their misconceptions. They tend to communicate in echo chambers that reinforce their outrage when the leadership of the major parties is unresponsive to their concerns. Consequently, in some countries we are seeing ill-informed Hooligans taking over major parties and the reins of government. In other countries splinter parties comprised of ill-informed Hooligans are attracting supporters away from major parties and making it more difficult for them to pursue coherent policy agendas. No matter which way it is happening, the growth in political influence of the ill-informed Hooligans seems likely to be detrimental to the future well-being of citizens in democratic countries.

Jason outlines a range of possible forms of epistocracy that might reduce the political influence of Hobbits and ill-informed Hooligans. Most of these suggestions involve taking the right to vote away from ill-informed people or giving their vote lower weight.

However, it is difficult to see how those proposals could ever be politically feasible while most citizens continue to have some faith in democracy. Even citizens who have shown no interest in politics in the past are likely to place some value on their right to vote. They are likely to perceive that it has existence value. The right to vote offers all citizens the potential to participate collectively in voting an oppressive government out of office, should the need arise.

It seems to me that when government by ill-informed Hooligans produces economic disasters the best response we can hope for will be for changes to be made in the rules of the game to tip the balance in favour of better economic policies. This could involve such things as more effective public debt ceilings, and making proposals for changes in tariffs and other trade barriers open to scrutiny by an independent agency responsible for reporting publicly on national economic benefits and costs. A couple of years ago I suggested some more fundamental institutional changes to make government in Australia more accountable in an article in On Line opinion.  

The question in the heading of this article is prompted by Jason’s favourite epistocracy proposal, government by simulated oracle:

 "Suppose there is a range of candidates from various political parties. We can ask citizens to provide their anonymously coded demographic information and then take a test of basic objective political knowledge. They then rank the candidates from most to least favored. Using these data, we can determine how the public would rank the candidates if the public were fully informed. Whatever candidates ranks the highest, wins." 

I am not attracted to the idea of adjusting the preferences of voters in this way, but I wonder whether a significant proportion of voters might be willing to accept the guidance of an oracle to help them to decide how to cast their votes. What I have in mind is that individual voters would be surveyed to determine their preferences and then offered impartial expert voting advice based on their responses. At present there are any number of commentators offering voting advice, but effort is involved for individuals to find and interpret this information. I am not aware of any oracles offering unbiased voting advice tailored to individual voters.

How many Hobbits and Hooligans would accept impartial expert advice about how to vote?
