Economic ideas matter. The writings of Adam Smith over two centuries ago still influence how people in positions of power – in government, business, and the media – think about markets, regulation, the role of the state, and other economic issues today. The words written by Karl Marx in the middle of the 19th century inspired revolutions around the world and provided the ideological foundations for the cold war. The Chicago economists, led by Milton Friedman, set the stage for the Reagan/Thatcher era and now fill Tea Partiers with zeal. The debates of Keynes and Hayek in the 1930s are repeated daily in the op-ed pages and blogosphere today.

Economic thinking is changing. If that thesis is correct – and there are many reasons to believe it is – then historical experience suggests policy and politics will change as well. How significant that change will be remains to be seen. It is still early days and the impact thus far has been limited. Few politicians or policymakers are even dimly aware of the changes underway in economics; but these changes are deep and profound, and the implications for policy and politics are potentially transformative.

For almost 200 years the politics of the west, and more recently of much of the world, have been conducted in a framework of right versus left – of markets versus states, and of individual rights versus collective responsibilities. New economic thinking scrambles, breaks up and re-forms these old dividing lines and debates. It is not just a matter of pragmatic centrism, of compromise, or even a ‘third way’. Rather, new economic thinking provides something altogether different: a new way of seeing and understanding the economic world. When viewed through the eyeglasses of new economics, the old right–left debates don’t just look wrong, they look irrelevant. New economic thinking will not end economic or political debates; there will always be issues to argue over. But it has the promise to reframe those debates in new and hopefully more productive directions.

An economics for the real world

The term ‘new economics’ is both vague and broad. It is easiest to define by what it is not. New economics does not accept the orthodox theory that has dominated economics for the past several decades that humans are perfectly rational, markets are perfectly efficient, institutions are optimally designed and economies are self-correcting equilibrium systems that invariably find a state that maximises social welfare. Social scientists working in the new economics tradition argue that this theory has failed empirically on many points and that the 2008 financial crisis is only the latest and most obvious example.

Defining what new economics is provides a greater challenge. As of yet there is no neatly synthesised theory to replace neoclassical orthodoxy (and some argue there never will be as the economy is too complex a system to be fully captured in a single theory). Rather new economics is best characterised as a research programme that encompasses a broad range of theories, empirical work, and methods. It is also highly interdisciplinary, involving not only economists, but psychologists, anthropologists, sociologists, historians, physicists, biologists, mathematicians, computer scientists, and others across the social and physical sciences.

It should also be emphasised that new economics is not necessarily new. Rather it builds on well-established heterodox traditions in economics such as behavioural economics, institutional economics, evolutionary economics, and studies of economic history, as well as newer streams such as complex systems studies, network theory, and experimental economics. Over the past several decades a number of Nobel prizes have been given to researchers working in what today might be called the new economics tradition, including Friedrich von Hayek, Herbert Simon, Douglass North, James Heckman, Amartya Sen, Daniel Kahneman, Thomas Schelling and Elinor Ostrom.

The common thread running through this broad research programme is a strong desire to make economic theory better reflect the empirical reality of the economy. New economics seeks explanations of how the economy works that have empirical validity. Thus behavioural economists run painstakingly crafted experiments to explain actual human economic behaviour. Institutional economists conduct detailed field investigations into the functions and dysfunctions of real institutions. Complexity theorists seek to understand the dynamic behaviour of the economy with computer models validated against data.

In my book The Origin of Wealth (2007: 97) I offered a table to summarise the contrast between traditional economics and the new economics perspective. I provide here an updated version.

Traditional economists often respond that the limitations of orthodox theory are well recognised and there is much work being done to relax restrictive assumptions, introduce more realistic behaviour, heterogeneity, institutional effects, dynamics, endogenous innovation and so on. They are correct and this work is a very positive development for the field. However, much of this work introduces just one element of realism to an otherwise standard model – a bit of behaviour here, a bit of institutional realism there, and so on. It is very hard or even impossible to relax all of the assumptions at once without throwing out the whole structure of the model – in particular without abandoning the core idea that the economy is an equilibrium system.

The radical challenge the new economists have accepted is to relax all of the unrealistic assumptions at once, move to the right column of the above table, and create an economics that has much greater fidelity to the real world. It is an enormous challenge and it requires a new toolkit and methodologies. But there is growing evidence that it is possible. That evidence comes from work in economics itself, but also from other fields that successfully model highly complex distributed systems that have many similarities to the economy – for example climate and weather, biological ecosystems, the brain, the internet and epidemiology.

Thus what has come to be referred to as new economics is not a single theory, or even a coherent body of work. It is a broad research programme best characterised by its unifying desire to embrace the messy reality of the economy. To accept human behaviour, imperfect institutions, and the complex interactions and dynamics of the economy as they really are rather than what an idealised model says they should be.

As policymakers and politicians often rely on the advice of economists and use their theories and ideas to frame their views and debates, this move towards realism in economics should be a good thing. If one thinks of economists as like biologists and policymakers as like doctors, then just as better biology has led to more effective medicine, so too should a more realistic economics lead to more effective policy.

In the rest of this essay I will outline three ways in which new economics may impact policy and politics. First, new economics may offer better tools for policy development and analysis – I will discuss an example from the financial crisis. Second, new economics has the potential to change the way we think of the role of government and policy itself, yielding new ways of designing policies in general. Third, new economics offers the intriguing possibility of developing new political narratives – this is the least developed aspect of new economics, but perhaps the one with potential for greatest long-term impact.

New tools for policy – examples from the crisis

“…Uncertainty has increased, but generally inconsistent with the perception of a “bubble,” the implied risks do not seem particularly tilted to the downside…” – US Federal Reserve 2006

In 2006, economists at the US Federal Reserve conducted an analysis of what would happen to the US economy if house prices suddenly dropped by 20 per cent. Officials at the central bank had noted the unprecedented run-up in house prices and become concerned. They ran the analysis on their state of the art macroeconomic model and the answer that came back was ‘not much’. Growth might soften, or there might even be a mild recession, but nothing that a few small interest rate cuts couldn’t handle. The model had done exactly what such traditional models are designed to do. It assumed everyone would behave rationally, markets would function efficiently, and the system would smoothly self-correct back to full-employment equilibrium.

At around the same time, Fed chairman Alan Greenspan was repeatedly asked by the media, congressmen, and others whether there was a housing bubble. Greenspan, a devotee of efficient market theory and fan of Ayn Rand’s libertarian philosophy, consistently replied that the runup in prices must have good rational reasons, there was little evidence of a bubble, and even if there was, the Fed should not intervene to burst it as the markets would eventually self-correct and government intervention would likely do more harm than good.

We all know what happened. The bubble burst and it triggered a catastrophic financial collapse, almost instantly wiped out $10.8 trillion in wealth in the US alone, nearly led to a second great depression, and we are still dealing with the consequences, most notably the ongoing euro crisis. In late 2008, Greenspan gave his famous mea culpa saying, ‘I have found a flaw’ in orthodox free-market theory, ‘I don’t know how significant or permanent it is. But I have been very distressed by that fact.

Might new economic techniques and models have given a different view? Might they have helped policymakers avoid such a disastrous outcome? A team of researchers led by John Geanakoplos at Yale, Robert Axtell at George Mason, my colleague Doyne Farmer at Oxford and Peter Howitt at Brown think so. They have constructed (Geanakoplos et al 2012) an agent-based model of the housing market that gives new insights into what caused the bubble and the model could eventually become a tool to assist policymakers in designing strategies for preventing or managing future bubbles.

Their model is radically different from the kind of models the Fed used in its 2006 analysis. Rather than look at the economy top-down and in aggregate, they model the system bottom-up. Their model has individual households in it, and for those owning houses rather than renting, individual mortgages backed by houses of a certain value. This population of households is heterogeneous – some have mortgages they can easily afford, some don’t, and the terms of their mortgages may differ. The households are assumed to behave in ways consistent with how behavioural economists tell us real people behave. Rather than doing elaborate calculations the agents in the model use rules of thumb (for example one shouldn’t take on a mortgage more than three times one’s annual income) but individuals vary in their use of such rules (some might be more conservative, others more risk taking). They also introduce institutional realism, for example if interest rates drop you might consider refinancing, but you might not automatically do it if the hassle factor is too high.

The initial version of the model uses detailed mortgage and household data from a single metropolitan area – Washington, DC. The team eventually plan to calibrate it with data from other major cities, and possibly the whole of the US and other countries such as the UK as well. Their preliminary findings reproduce the dynamics of the bubble building up and then bursting. Unlike traditional analyses, the model doesn’t gently self-correct, it crashes (see figure 11.1a). They then run policy experiments on the model, asking what policymakers might have done to prevent the bubble forming, or at least stopped it building once it was clear there was one. Analyses using traditional models have tended to blame the bubble on overly loose monetary policy from the Fed. So the team tested scenarios where policymakers raise interest rates. The bubble is indeed moderated, but not eliminated. But interest rates are a blunt instrument and such tightening would also have slowed growth in the rest of the economy. So the team also tried a regulatory intervention – preventing banks from loosening their loanto-value ratios. During the heat of the bubble, banks competed with each other to give loans, loosening their standards. The team’s model shows that by intervening to prevent these standards from slipping, policymakers might have eliminated a key dynamic in the bubble’s formation, prevented the subsequent bust, and done so more effectively and without the collateral damage caused by a big interest rate hike.

There are also efforts to use similar approaches to go beyond the housing market and look more broadly at the relationship between the financial sector and the macroeconomy. When the crisis hit in 2008 many senior policymakers were shocked by how little help they received from the formal theories and models of traditional economics. Reflecting on this later, European Central Bank (ECB) president Jean-Claude Trichet said: ‘As a policymaker during the crisis, I found the available models of limited help. In fact I would go further: in the face of the crisis, we felt abandoned by conventional tools.

Central banks, finance ministries, and economic regulators all have large staffs of well-trained economists, fancy models and vast quantities of data. But when the crunch came, their theories and models could not describe what they were experiencing. The Economist reported that the Bank of England’s large macro model wasn’t much help because it didn’t have banks in it. It is hard to make policy in the middle of a banking crisis if one’s economic model doesn’t have banks in it.

The reason these models and formal theories were of limited use is they were built on assumptions that people are rational, markets always clear, bubbles can’t form, and that banks are just boring bits of plumbing that shuffle money from one part of the system to another and can be safely ignored. It is therefore not surprising that when people started panicking, markets were not clearing, a massive bubble had just burst, and the banking system was on the verge of collapse, that models with such assumptions were not that helpful. It is a bit like building a flight simulator where it is impossible for the airplane to crash.

Yet a crisis is exactly when a model should be at its most helpful. The crisis was something beyond the experience of most of the participants; it was highly complex and moving very fast. Intuition and ‘mental simulation’ can be unreliable in such circumstances. Models can be very helpful in augmenting and informing judgment. They can keep track of lots of variables, enforce logical relationships, and search spaces of possibility more rigorously and quickly than the human mind can alone. If policymakers had had better models, they might have been able to run more and different policy scenarios and gained different insights into the crisis. Politics and judgment will always play a key role in major policy decisions – but better models might have given the policymakers better options to choose from.

Andrew Haldane (2011), executive director for financial stability at the Bank of England, has teamed up with Lord Robert May, one of the world’s pre-eminent mathematical ecologists and applied ideas from network theory, epidemiology, and food webs in ecology to look at the problem of financial contagion in the banking system. Their work has potentially significant implications for structural reform of the banking system. Doyne Farmer, Domenico Delli Gatti and I are leading an effort supported by the European Commission called Project CRISIS, which is a consortium of researchers building an agent-based model of the interlinked banking system and macroeconomy to provide a simulation platform for policymakers to develop and test policy ideas. While the work is at an early stage and there are many challenges to building a tool policymakers can rely on, there has been significant interest from central banks, finance ministries, regulators, and other economic policymakers.

While the examples cited draw from behavioural economics, network theory, experimental economics, complex systems thinking and use computer simulation, there is also new economic work with direct public policy relevance going on in economic history, institutional economics, evolutionary economics, and a variety of other traditions and toolkits. And there is work going on not only on the financial crisis, but also on topics such as climate change, inequality, poverty, economic development, innovation and growth, and other policy-relevant topics. The challenge is bringing this promising, but still early-stage work, into the policy environment.

Policymaking in an uncertain world

In addition to providing new models and tools for specific issues like the financial crisis, new economics offers a potentially different way of thinking about policy more broadly.

Traditional economics views the economy in a fairly mechanistic way. If people are rational and we want to change their behaviour then we just need to change their incentives. Thus, a lot of policy is conducted through tinkering with the tax code or subsidies, for example if one wants more innovation, give an R&D tax credit; if one wants less smoking, tax it heavily. Of course people aren’t immune to such incentives, but often the response is far less than policymakers would like.

Likewise, traditional economics views the economy as naturally being in a state of efficiency, and so by definition any interventions move it away from that state, making it less efficient. Thus, interventions are justified by market failures, the need to create some public good, or the need to avoid some negative spillover effects or externalities. For example, state support of R&D might be justified if there are market failures, or taxing smoking might be justified to reduce the externalities smokers create for non-smokers.

Finally, policies are evaluated through the lens of cost–benefit analysis, where future benefits and costs are projected and compared. For example, much of the debate on climate change policy has been over competing forecasts of future costs from climate damage and their likelihood of occurring, versus the potential benefits of action to avoid those costs.

These mechanistic approaches to policy and regulation are still what are taught in most undergraduate and graduate university programmes, and they pervade the civil service and the pool of advisers and experts that governments rely on for policy development and assessment.

Both economists and policymakers have also ignored what George Soros calls the ‘reflexivity’ of the economy. Actors in an economy take actions which change the economy, those changes then change the actors’ perceptions of the economy, which then changes their actions, and so on. But as humans are fallible and our perceptions and interpretations may not always match reality, the two-way interplay between perceptions and actions can send the economy off on a course far from the optimal path predicted by orthodox economic models. Bubbles are a prime example. Soros has also pointed out that these reflexive interactions can create ‘predator–prey’ dynamics between regulators and those being regulated. Regulators take an action to address a perceived problem, that changes the perceptions and actions of market participants, which in turn creates a new set of problems triggering further regulator actions, and so on. Over time this infinite chase between fallible regulators and equally fallible market participants leaves a trail of rules, structures, and institutions that has a major effect on shaping the evolution of the economy.

So how might new economics move us beyond the mechanistic view of policy and regulation, and towards a view that takes into account the complexity, unpredictability, and reflexivity of the economy?

My view is that we must take a more deliberately evolutionary view of policy development. Rather than thinking of policy as a fixed set of rules or institutions engineered to address a particular set of issues, we should think of policy as an adapting portfolio of experiments that helps shape the evolution of the economy and society over time. There are three principles to this approach:

First, rather than predict we should experiment. Policymaking often starts with an engineering perspective – there is a problem and government should fix it. For example, we need to get student mathematics test scores up, we need to reduce traffic congestion, or we need to prevent financial fraud. Policy wonks design some rational solution, it goes through the political meat grinder, whatever emerges is implemented (often poorly), unintended consequences occur, and then – whether it works or not – it gets locked in for a long time. An alternative approach is to create a portfolio of small-scale experiments trying a variety of solutions, see which ones work, scale-up the ones that are working, and eliminate the ones that are not. Such an evolutionary approach recognises the complexity of social-economic systems, the difficulty of predicting what solutions will work in advance and difficulties in real-world implementation. Failures then happen on a small scale and become opportunities to learn rather than hard to reverse policy disasters. It won’t eliminate the distortions of politics. But the current process forces politicians to choose from competing forecasts about what will and won’t work put forward by competing interest groups – since it is hard to judge which forecast is right it is not surprising they simply choose the more powerful interest group. An evolutionary approach at least gives them an option of choosing what has been shown to actually work.

One area where evolutionary experimentation on policies has been tried explicitly is in development economics, where different interventions are tried across a portfolio of villages or regions, the results measured, and successful interventions scaled up. Michael Kremer at Harvard has conducted field experiments on issues ranging from policies to improve teacher performance, to getting farmers to use fertiliser. David Sloan Wilson, a leading evolutionary theorist, has tried an evolutionary approach in a fascinating case study of improvement efforts in his city of Binghamton, NY. The individual states in the US also provide such a natural evolutionary laboratory on issues ranging from healthcare to education. Other initiatives where there is a diversity of approaches, such as charter schools, end up creating an evolutionary portfolio of experiments, though more could be done to harvest those experiences and scale-up the successful experiments.

Second, policies and institutions should be made as adaptable as possible. The predator–prey dynamics between regulators and participants mean there is a never-ending battle between regulators trying to draw rules as tightly and specifically as possible, taking into account all possible contingencies, and armies of lawyers and accountants trying to find ways around them. This often leads to very rigid regulatory structures overlaid on highly dynamic markets. A better approach is to create rules that provide general frameworks, but then adapt to specific circumstances. One example is how California’s building codes have succeeded in reducing energy consumption. Rather than try to predict the state of energy efficiency technologies in future years, the regulators created a set of general performance standards that automatically ratchet-up as the state of technology improves – the standards are set by whatever the best developers are doing at the time. And rather than specify how those standards are to be achieved, developers are offered a choice of pre-approved practices, or experimenting with new ways of meeting the standards. Some developers are happy to go with the pre-approved practices, but others who are competing to meet the standards in less costly or more aesthetic ways have incentives to experiment and innovate. Thus the regulations and state-of-the-art building practices co-evolve with each other.

One could imagine similar approaches being applied in areas such as health, transport and education where general performance standards could be set, incentives created for experimentation and innovation, and then have the standards automatically adjust as the system evolves.

Third and finally, policymakers need to think of themselves less as social engineers and more as ‘system stewards’. As Michael Hallsworth from the Institute for Government (IFG) explains, rather than engineering specific outcomes, government’s role as system stewards is to create the conditions in which interacting agents in the system will adapt towards socially desirable outcomes. Policy design and implementation are thought of as integral rather than separately, and mechanisms for feedback and continuous learning and improvement are built-in from the beginning. The IFG recognises, however, that such an evolutionary approach may not be suitable for all circumstances. In some situations, for example emergency disaster relief or national security situations, a traditional top-down approach may be required when speed is of the essence, where clarity and consistency is critical, or when the capacity of actors further down the chain is limited.

A major challenge for these more adaptive approaches to policy is the political difficulty of failure. Learning from a portfolio of experiments necessitates that some experiments will fail. Evolution is a highly innovative, but inherently wasteful process – many options are often tried before the right one is discovered. Yet politicians are held to an impossibly high standard, where any failure, large or small, can be used to call into question their entire record.

Likewise, politicians are always expected to have clear plans, and simple, easy to understand answers in which they have unshakeable confidence. You would never hear a politician give a speech where she or he says ‘It is a complex problem, we’re not sure what to do. But we have several good ideas that we’ll try on a small scale. We’ll then ramp up the ones that work and close down the ones that don’t, and then have a good shot at solving it.’ For some reason we don’t mind such an approach when it is used by doctors looking for new drugs, energy companies looking for oil, or venture capitalists looking for the next big idea. But we seem to prefer politicians who tell us the world is simple and predictable, even though we know it to be complex and unpredictable.

So an explicit, widespread use of new economic approaches to policymaking may require some education of citizens, the media and politicians themselves on the risks of overconfident top-down solutions, and the importance of small-scale failure as a way to learn and prevent large-scale disasters.

Politics – neither left, right nor centre

Perhaps the most intriguing, but least developed, potential impact of new economic thinking could be on politics itself. The tradition of splitting politics into left and right camps dates back to the layout of the French National Assembly in the Revolution of 1789. Over the two and a quarter centuries since, both left and right have seen their political narratives evolve. The left has travelled an arc from Marx and Rousseau, through Victorian social reformers, to Keynes, the New Deal and to modern European notions of social democracy. Meanwhile, the right has travelled from Smith and Hume, through the Austrians, the Chicago revolution, Thatcher-Reagan, and to today’s European centre-right parties and America’s radicalised Tea Partiers. At the heart of both narratives have been differing views on the nature of the economy, the roles of the individual and the state, and notions of freedom and social justice.

New economics has the potential to significantly reframe these debates. It isn’t merely a matter of centrist compromise, of just splitting the difference. Rather it is a different frame that agrees with the right on some things, with the left on others, and neither on still other areas. For example, new economic work shows that Hayek was ahead of his time in his insights into the power of markets to self-organise, efficiently process information from millions of producers and consumers, and innovate. But new economic work also shows that Keynes was ahead of his time in his concerns about inherent instabilities in markets, the possibility that markets can fail to self-correct, and the need for the state to intervene when markets malfunction. Likewise, new economics research shows that humans are neither the selfish individualists of Hume nor the noble altruists of Rousseau, rather they are complex social creatures who engage in a never ending dance of cooperation and competition. Humans are what researchers such as Herb Gintis and Sam Bowles (2005) call ‘conditional co-operators and altruistic punishers’ – our cooperative instincts are strong and provide the basis for all organisation in the economy, but we also harshly punish cheaters and free-riders, and compete intensely for wealth and status.

Traditional economics tends to frame things in terms of market efficiency versus market failure, and those on the right emphasise the efficiency part and those on the left the failure part. This leads to differing views on the justice of market outcomes. The right generally believes that if markets allocate resources in the most societally efficient way then any interference in that process is morally suspect. Market outcomes may be unequal, but that is because the distribution of talent and hard work in the economy is also unequal – in general people get what they deserve. The left on the other hand tends to see unequal outcomes as an injustice in and of itself, and emphasises how powerful interests use markets to their benefit and can abuse or leave behind the less powerful. People often don’t get what they deserve and the state must intervene to protect the vulnerable, and correct both unfair processes and unfair outcomes.

To date there has been very limited work on questions of inequality, social welfare, and social justice from a complex systems or evolutionary economics perspective. But there are hints of a different view. Even models that start with perfectly equal or random distributions of income or wealth can produce unequal outcomes statistically similar to what is observed in the real world. These outcomes emerge because small, random differences can lead to self-reinforcing feedbacks that pull apart the tails of the distributions. For example, two people might start off with equal ability and starting circumstances, but by chance one gets an early lucky break and the other doesn’t leading to compounding differences in income over the rest of their lives. Thus even with equal initial endowments and a fair process, inequality may emerge. The right might be wrong in that inequality might not be merely the result of unequal distributions of talent and hard work and therefore justified. But the left might also be wrong in that inequality might not necessarily be the result of unfair processes. At the same time, the right might be correct that unequal outcomes are a natural and difficult to avoid outcome of market interactions, while the left might also be correct that a growing body of evidence shows that unequal outcomes are strongly associated with a number of social pathologies justifying state intervention to ameliorate those outcomes. In other words, a new economics perspective might not just split the difference on debates such as inequality, it might rescramble the terms of such debates.

Finally, new economic thinking may also provide the foundation for new political narratives. Eric Liu and Nick Hanauer, in their 2011 book The Gardens of Democracy, explore the possible shape of such a narrative. They liken the narratives of traditional economics to ‘machine-thinking’ and advocate a shift to ‘garden-thinking’ that emphasises the dynamic, constantly evolving nature of the economy and the interconnectedness of society. The state then plays the role of gardener helping create the conditions in which the garden of society can flourish.

It took traditional economics decades to move from academic theory to providing a foundation for policymaking and a basis for our political narratives. New economic thinking still has some distance to go to mature as a body of economic theory, and no doubt it will take time to fully develop the policy and political implications of these ideas. This journey might not end our political debates, but it has the potential to make them far more productive for society.

    This was a wonderful manifesto, although I suspect there is an error.

    I expect you mean Hobbes rather than Hume. Hume talked a lot about human beneficence (as, incidentally, did his good pal Adam Smith).

Government decision makers invest in economic indicator based education programs. Friendship cube technologies are attached to every macroeconomic indicator. Our public company increasingly employs public-private partnership economists to advise policy makers, who influence public investment decisions and curriculum policy that impacts our ability to create value and jobs based upon sales and installations.

  • RAP77

    No mention of the fact that all current economic models are based on expansion. The economy must grow continuously or it falls into recession. No mention of any kind of steady state economic models.

    This expansionary view grew from the history of population growth, but in advanced economies (late capitalism if you prefer), population growth declines and eventually begins to contract. Thus we hear regularly that China has a problem of no population growth (young workers will not be able to support, through taxation, older retired workers) so they need to have more children. This is faulty in that China is grossly overpopulated and their fast-growing economy was incorrectly modeled on the obsolete Western model of continuous growth, and is doomed to crashes.

    The other problem not mentioned here is the impact of robotic automation. Full employment is becoming a obsolete concept. The bigger problem is how to keep people occupied when they are not employed full time and how to provide a living income for them.

    This article is thoughtful but seems based on old-school ideas of economies, despite the references to new economics. For example:

    “…policymakers need to think of themselves less as social engineers and more as ‘system stewards’.”

    I don’t think this is correct. Policymaking, governing, is social engineering. That is, good governance avoids extremes in wealth and poverty. “System stewards” implies that economic systems are self-governing and rational, a concept this author refutes early on.

  • Jan de Jonge

    In many faculties of economics courses in economic philosophy and methodology have been removed. I see this reflected in this article, which misses references to economic philosophers as Hausmann and McPherson, or Joan Robinson for example (the exception is Sen) and methodologists as Robbins or Blaug or Adolph Low with very different approaches to economic science.
    I also have problems with your definition of the old left-right discussion as being between government or market. The discussion was usually between the idea of a society having a market and a society being a market. In a society that has a market it was of course possible to propose measures for regulating the market when necessary.

      Americans used to study classical history: the writers of the constitution clearly looked to Rome (republic, senate) for their inspiration.
      They would have learned then that right versus left is not about government versus markets, but debtors versus creditors. Competitive markets create a few winners (who acquire wealth) and a lot of losers (who must borrow the means to survive from the wealthy); unless government can achieve enough redistribution to stop the losers becoming desperate the market system itself will be rejected (as with Brexit).

        Your reply is childish and I shouldn’t even give you my time, but I will.

        You’re equating the left with the “communist” states of the Cold War and associating their crimes with “the left” like there’s a leftist manifesto for killing people. But let’s not forget that during the Cold War, the opposition to the Soviet states also commited a lot of crimes in the name of their ideology. For example: I’m latin american & the US funded a good number of military dictatorships here who killed and tortured a lot of political opposition. They also did the same in other parts of the world, and are still doing (Honduras being a very recent example) today.

        So, I guess that if the people assassinated by the USSR/China during the Cold War in the last century made the left “lose the argument”, those other thousands (if not millions) of dead people financed by US and it’s allies count to “the right” too? Both sides did it, both sides were wrong. Also the Cold War is over if they forget to tell you.

  • Some great aspects to this article.

    I love the description of one of the major threats we face: “Policy wonks design some rational solution, it goes through the political meat grinder, whatever emerges is implemented (often poorly), unintended consequences occur, and then – whether it works or not – it gets locked in for a long time.”

    And the following:

    “An alternative approach is to create a portfolio of small-scale experiments trying a variety of solutions, see which ones work, scale-up the ones that are working, and eliminate the ones that are not.” Is straight out of one of Snowden’s lectures on modifying complex systems. And Snowden stressed the need to include both intelligent and stochastic processes in the selection system. Sometimes the most successful systems are not at all what the experts expected to work. Sometimes the best answers come from outside of existing dominant domain spaces.

    And I have real problems with the description given of evolution.

    “Evolution is a highly innovative, but inherently wasteful process – many options are often tried before the right one is discovered.”

    The idea that there is a “right one” is no longer tenable.

    Once one comes to grips with the infinite complexity and dimensionality of both strategic domain spaces and algorithm possibility spaces, then it becomes clear that most real problems have infinite possible solutions with very similar utility, and some of those will be much closer to existing systems in terms of complexity and relatedness in the spaces concerned.

    How we search such possibility spaces, and how we evaluate possibilities, is very much the issue.

    Evolution essentially starts out as some version of a random walk through some set of possibility spaces, with differential survival providing the filter to select amongst variants. Differential survival is very sensitive to spatial and temporal variations in all dimensions of the distributions of attributes present. Hence we see the diversity of living systems we have on this planet – all of them the result of the same length of time here, but with slight variations in the conditions present locally over space and time.

    In a very real sense, we are simply evolution’s latest breakthrough in the realm of searching new possibility spaces.

    In another sense, we are still in our infancy in understanding the complexity of the interactions present in living systems, speaking as someone who has had half a century of interest in biochemistry, complexity, systems, algorithms, strategy and evolution in biological, social and technological domains.

    “But we seem to prefer politicians who tell us the world is simple and predictable, even though we know it to be complex and unpredictable.”

    That is an inevitable outcome when our systems have a large intentional component designed to dumb people down and constrain them within manageable and predictable sets of parameters.

    “At the heart of both narratives have been differing views on the nature of the economy, the roles of the individual and the state, and notions of freedom and social justice.”

    That is partially true, and it obfuscates at least as much as it clarifies.

    The issues are far deeper.

    This article does identify many real issues, and it leaves many more, far more important issues, untouched.

    Exponential change;

    Automation;

    The fundamental unpredictability of aspects of reality, including both Chaos and maximal computational complexity;

    Individual empowerment;

    Existential risk.

    The above list of 5 issues combine to make all exchange based thinking not simply obsolete, but actually dangerous.

    We live in a time of exponential change where many aspects of our reality are on doubling times that are now around (and in some cases well under) a year.

    Traditional economics is structured to deal with doubling times of around 30 years, which can work reasonably well with linear models over time-spans of 10 – 15 years.

    So if you are in a noisy environment, with noise at around the 5% mark, then by the time an exponential signal emerges clearly from the noise, until it reaches 100%, is only 5 doublings. In the realm of technology, some of those give only 4 years from emergence to dominance. In the realm of social behaviours, in some classes it can now be usefully measured in days or hours.

    Automation gives us the ability to deliver universal abundance without labour. By definition such behaviour has zero or less value in classical economics, but huge value for individual human beings.

    Most people are starting to understand something of chaos theory, but few have yet come to grips with the idea of maximal computational complexity coming from Wolfram’s NKS. It has some overlap with aspects of chaos, and it has other aspects that are profoundly different. They are simple rule based systems, common in the core of many biological systems, that are not predictable by any mechanism that is less computationally complex than simply letting them do what they do.

    The thing few people have gotten about biology and evolution, is that it doesn’t have to work all the time, just often enough so that on average, over time, it is of net advantage in some set of contexts. Most people never really get a good handle on the temporal aspect of contexts, in the sense that low frequency high impact events can select strongly for traits that in all other circumstances are at best neutral, and at worst quite negative. We all carry many such things.

    This article correctly identifies that in many situations, small differences can be amplified to lead to large differences. What the article fails to address is the fact that with automation, we have the ability to ensure that all individuals enjoy a high minimum standard of the goods and services required to empower a high modern standard of living. If everyone has that high basic minimum, then the fact that some few have exponentially more is not a major issue. That exponential difference only becomes a serious risk factor when some (most) lack the basics. And the basics are quite simple, air, water, food, housing, clothing, education, communication, transport, health-care, and reasonable freedom of movement and freedom of access to physical tools, materials and energy to do whatever they reasonably and responsibly choose to do (in a context of the ecological and social reality of their situation). Such a reality would seem to offer sufficient diversity that the vast majority of people would be able to find a place where they could do what they wanted in a context of other “like minded” individuals.

    Existential risk is real, and has many dimensions. Not something to be paranoid about, and something worth developing effective risk mitigation strategies. As with most aspects of infinity, the deeper one goes in explorations, the greater the number of both instances and dimensions one encounters.

    The new economics will be built on Promise Theory invented by Mark Burgess. While economic models are developed economics will change before our eyes as we democratise money using ideas from Promise Theory. Here is one way to do it.

    https://kevinrosscox.me/2016/05/21/democratisation-of-money/

    When we remove the value of money tokens and make them free we make it easier for us to cooperate for the common good. Because money tokens are free there is no market for tokens.

    Instead of optimising money creation we optimise creation of all value – whether it is expressed as money or as something else.

    We solve the Tragedy of the Commons by making the value of the Commons available to all. We replace ownership of the commons with custodial-ship of the commons. This includes the common planet. It means we can set about stabilising our planet to make sure it continues to support us.

    • Douglas Levene

      Can you please explain how you solve the tragedy of the commons – which is caused by communal ownership – would be solved by “making the value of the Commons available to all,” i.e., by communal ownership?

      • Chris Cook

        First, distinguish between the right of exclusive use of the Commons, and the right to the fruits of use (usufruct) of the Commons.

        It is completely possible to create an agreement – I call it a ‘Nondominium’ – whereby the use and fruits of use of commons in collective custody are shared within an associative/partnership based protocol between a co-operative of users and a co-operative of investors (of money or money’s worth) in the stream of usufruct.

        The key is that investment is made using promissory credit instruments (‘stock’) returnable in payment for usufruct – and issued by the promissor at a discount in exchange for value received from the acceptor – and not the debt (loan stock) or equity (common stock) instruments which came along 300 years ago or so.

        So one could imagine £1.00 denominated credits returnable in payment for land use/rentals, or alternatively a credit instrument returnable in payment for the energy equivalent of 10 kWh of renewable electricity.

        • Douglas Levene

          I got lost with your first sentence. If someone has the right of exclusive use of the Commons, then it’s not a commons. Nothing after that made any sense either.

          • Chris Cook

            Then let’s distinguish – from the bundle of rights which comprises ‘ownership’ – the ‘right to exclude’ from the right of use if it confuses you.

            Firstly, there are dozens of rights of use, but one of the most important is the right of residence in a particular location, either in a building or something less permanent.

            Now, I don’t know about you, but I prefer to have exclusive use of the place where I live, so I require the right to exclude others from this location/land. To the extent that exclusive use is granted then that means the commons has been enclosed.

            Secondly there’s the question of the fruits of use or usufruct, which derives from the use of land. These rights are typically exercised by those in authority, such as a sovereign (feu duties, crown rentals); temple or church (tithes); nation state government (land taxation); and increasingly we have seen land rental value capitalised and sold off via bank mortgage loans to investors.

            You assume that communal ownership necessarily means COLLECTIVE ownership.

            I suggest that it is quite possible for stakeholders in land to come to collaborative agreements whereby those who have exclusive use of the Commons compensate those they exclude. Taxation of land rental values is one such (imperfect, since it involves the State) mechanism.

            Finally, kindly keep the discussion civil and I shall continue to do the same.

        • Aren’t these quite old concepts from the non-feudal side of medieval property/usage arrangements, which then had been scrapped with – in England – hedging, i.e. the privatization of the commons?

          • Chris Cook

            In my view these ancient concepts and instruments – suitably restated and automated – enable a resilient networked political economy to evolve and spread virally bottom up.

            Within as suitable framework agreement, direct ‘peer to asset’ investment in prepaid land rental/location use value will in my view outcompete conventional deficit-based investment & tenure.

            This is because there is no economic rent (‘something for nothing’). ie it benefits from the Co-operative Advantage.

  • Rafiki

    As fascinating and thought provoking as I find all these theoretical discussions, one key factor in the operation of the economy of most western countries is conspicuous by its absence. This is the role of paid work in keeping the economy generating income and the means to consume. Not only has the loss of secure, well paid work diminished exponentially in the past two decades throughout the First World economies, it appears to be continuing without abatement. Yet, anyone who observes the impact of low employment prospects, casualization of labour and reduction in working conditions can see not just the economic impacts of lack of the means to consume. We have a plethora of social problems directly linked to lack of meaningful and decently paid employment. Surely working for a living is central to this ‘capitalistic consumerism’ and must be examined as an aspect of the slowing of economic activity and all the effects this has had on people’s economic lives? Where’s the logic in cutting back government spending and encouraging private enterprise to reduce costs when clearly governments and business will inevitably lose taxes in the first instance and consumers in the second? Yet, despite people like Piketty bringing the effects of economic inequality to the fore, conventional economic theory seems to be stuck, like a cow in the mud, in neoconservative claptrap. We hear our politicians bleating about balancing the books, yet the means is staring them right in the eye – creating employment and therefore stimulating the economy. And the author is so right about the debate between Left and Right. There is little, at least in Australia, to separate their economic principles. It’s just a matter of how far towards austerity they are prepared to go. All the while, the media faithfully repeats the propaganda where running an economy appears to be little more than running a household budget on a large scale. We need to discuss the effects of lack of employment on a broad, economically sound basis and reverse the trend begun by business and now taken up by governments, to reduce labour and not give anything tangible back to the community or the economy at large.

  • Douglas Levene

    OK, so you think that we can identify bubbles in asset prices that are bound to pop? Why don’t you try using your great powers on housing prices in Shenzhen and Shanghai. By most measures (average income/price), both markets are in a big bubble. Should investors short those markets? For how long? One year? Two years? Ten years? You think this is too hard a test? OK, tell me what the price of the US long bond will be 12 months from today. My point is that markets are not predictable except in hindisight. My second point is that markets still do a far better job of allocating resources than politicians. Every cognitive weakness that the behaviorists identify in individual consumers applies equally if not more so to the politicians and bureaucrats to whom you would cede power.

  • Rob Lewis

    Sadly, no amount of empirical evidence will persuade ideologues to abandon their pet theories if those theories serve the interests of the rich and powerful. See, e.g., “Tax cuts pay for themselves.”

  • HansSuter

    In the mean time how about prosecuting fraud ?

  • “But new economic work also shows that Keynes was ahead of his time in his concerns about inherent instabilities in markets, the possibility that markets can fail to self-correct, and the need for the state to intervene when markets malfunction.”

    Well, this sentence doesn’t inspire confidence.

    The distribution of market crashes is a lot like the distribution from snow avalanches and forest fires. This suggests that stability is an illusion. Also, any efforts to maintain or facilitate stability will only makes things worse.

    • John M Legge

      I have a go at catastrophe theory here: http://www.johnmlegge.com/blog/driving-brexit-catastrophe/
      A large ship at sea is intrinsically unstable as wind, waves and tide push it off its course. Under an incompetent helmsman catastrophic failure is all but certain. Nevertheless, most ships complete their voyages safely because the helmsman (or helm-computer) detects small deviations and corrects them before they become large. The critical issues are:
      (a) loop delay – how long between a deviation and correction, and
      (b) robustness of the control system (generally a matter of experience informed by theory).
      An economy managed on orthodox principles is like a ship with no helmsman and a single button for use in an emergency which throws the engines into full reverse. From 1947 to 1972 Western economies were competently managed, with growing incomes, low unemployment, and stable or even declining inequality. The governments that achieved this were considered right wing at the time: Menzies in Australia; Eisenhower in the USA; Churchill/Eden/Macmillan in the UK. It can be done.

  • Robert Price

    Oh dear. Money still comes from government, and government policy can still guide where the money goes. I take it this is yet another extremely well paid individual completely separated from the harsh realities of life in Britain today; perhaps yet another right winger in the Green Party not wanting the Party to argue for measures to redress the imbalance in income and reduce the inequality.

  • John Bunzl

    The evolutionary arc of both left and right economics, as described, seems incomplete. The need for all governments of whatever party to keep their national economies internationally competitive has caused a substantial fusion of right and left, not in terms of their respective ideologies which the article accurately describes, but in terms of what right and left governments actually end up DOING when they are in power. Centre-right governments may deregulate faster and centre-left ones slower, but in the round when all’s said and done, there isn’t so much difference anymore.

    Which is why people all round the world are giving up on mainstream political parties and moving to the extremer ones. But little do they know: even the more extreme ones will not be able to buck the need to stay competitive. We are living in a new era – and it’s a global one. You could say that the big lesson of the Cold War was that markets are a more efficient way of running an economy than ‘command and control. The lesson globalization is trying to teach us is that markets (the god of the political right) need governance (the god of the left). They both need each other. But of course, since we now have a GLOBAL market, we need properly functioning global governance to match (i.e. appropriate international agreements which include differentiations according to each nation’s needs, appropriate re-distributions, etc.)

    How to achieve that? One possibility is http://www.simpol.org

  • cmbennett01

    Your “Traditional Economics” are rather difficult to buy. It’s almost a caricature. I find it hard to believe anyone would posit a perfectly rational individual. I don’t know, maybe economists would. Your “New Economics” on the other hand, sounds like a TED Talk.

  • Minding

    A new approach to economics needs to factor in social pathologies as more than passing problems. From desperation, abuse, corruption and narcissistic self-absorption to sociopaths and psychopaths, ‘social pathologies’ are integral to human behavior and therefore an economic system must account for this.

  • Just to be pedantic, the ‘left’ has talked about the power of markets. I believe the PARECON economists, as well as Proudhon talked about such

  • progrock

    In the table we have “growth” mentioned but this deserves it’s own row:

    classic – an increase in wealth
    new – an increase in fiat money

  • Richard A. Rosen

    I would not frame your basic view the same way. On the whole, I would say that the “left” as you label it, has more interesting and relevant theories for the real world. This includes economists you should have mentioned, but did not, such as Marx and Piketty. A related point is that your essay did not even mention political power once, which usually “follows the money”, especially in the United States. It did not discuss capitalism, and alternatives to it as potentially important institutions. For example, you did not even mention current publicly- owned corporations, and they role they play in the economy, as well as many other types of currently existing non-profits. Your essay did not even discuss the need for models of the current economy which assume that corporations are more important economic actors in shaping the economy than individuals. I don’t think you even mentioned corporations and the power they exert in the economy, which is clearly major. So while almost anyone would agree that we need to continually re-think economic theories, I feel that you did not mention many important ingredients that must be a part of new economic theories. In summary, you can’t have a theory of the economy without including all the different kinds of existing economic and political actors, including different kinds of government agencies that directly effect and carry out capital investments.

    • anotherneighborhoodactivist

      The essay also doesn’t discuss the declining supply of net energy, or capitalism’s essential reliance on cheap access to energy to keep our complex debt based economy afloat.

  • wjohnfaust

    It is good to see the traditional, reductionist economic system challenged, particularly since it is so easily rigged. Nothing involving humans (individually or jointly) is likely to be captured by such a simplistic system.

    However, like weather or other chaotic, complex systems, there may be a limit on forecasts into the future. For weather, a six-day forecast is a challenge and a 20-day forecast (I think) is the theoretical limit. If economic systems are chaotic (likely), then that truly changes how they should be “managed”.

  • Loren Sickles

    Glad to see the reference to “Gardens of Democracy” (Liu & Hanauer; 2011), I would like to see an update that takes into consideration the ideas expressed in “Complexity and the Art of Public Policy” (Colander & Kupers; 2014).

  • M A J Jeyaseelan

    Economic problems ought to have been discussed in a framework of right versus wrong and not in a framework of right versus left. The simple truth is that both the so called right and left have gotten it all wrong. They continue to confuse the world by presenting the same old murky wines in newer and shiny bottles. There is no way politics is ever going to solve any economic problem. Politicians have made it only worse always and in all probability, both politicians and money bags would continue to hold economists in hostage.

    I am beginning to believe that all these tea party discussions are part of a wider conspiracy to perpetuate the confusion, so that the rich can continue to take advantage of the wily economic theories and instruments that empower them to usurp and steal incomes and savings of others legitimately. I was horrified to read in the Guardian today about a certain business family in the US funding 300 academic courses at colleges and universities, where the syllabus is dictated by the right: students learn that Keynes is bad, sweatshops are good and climate change is a myth. https://www.theguardian.com/commentisfree/2017/aug/07/trump-out-in-year-usa-problems-just-beginning-paul-mason?CMP=share_btn_fb

    Economists have in general been subservient and I have now reasons to believe that most of them are also sold out to the rich like their crony politicians. It is time people stopped taking economists on their face value. Their academic integrity has certainly come under all sorts of smoky clouds. Economics can now be rescued only by those who are not dependent on economics for their livelihood.

    Take it from me, all the diversity and complexity that that is beginning to haunt economics more intensely than before is the direct result of the faulty foundations upon which most of the extant economic theories have been built. Economics has also suffered considerable damage from people from other sciences poking their nose without ever bothering to understand the economic phenomenon correctly.

    Fundamental economics is very simple as any truth always is. Economics is essentially a social science dealing with the collective management of material resources for securing and promoting the livelihood and well being of all. Micro economics needs to be derived from the macro requirements. There is no way to reverse this function.

    I can go on and on. But, I will stop here and recommend that you read my article hyper linked below to get a hang of what needs to be done to revive economies and economics.

    I heard only faint ffragmented echoes regarding the ethics behind the decision- making in economics. If people only CARE about economics, the material, then that is all we are going to look at. What if we allow ourselves to CARE for our context in general, us and others in it? #EthicsofCare could be the overarching body of reference for casuistic ethics and new ‘garden’ economics.

  • Reron

    This is the same Technocrat nonsense that has lead to worldwide debt saturation and the failure of democracy. If it’s centralized it’s outdated. Today’s Technocrat cannot even define money, let alone manage it. There is more evolving than money and Technocrats are tied to a failed methodology.

  • Haynes Goddard

    “New economics does not accept the orthodox theory that has dominated
    economics for the past several decades that humans are perfectly
    rational, markets are perfectly efficient, institutions are optimally
    designed and economies are self-correcting equilibrium systems that
    invariably find a state that maximises social welfare.”

    Where do you get this? It certainly was not in my various textbooks from which I taught over many years, and much less so in the current literature. Rather, perfect markets represent an ideal against which to judge actual market outcomes, and provide suggestions for improving them.

    One example: how much environmental portectiion should there be? From perfect market theory, the right amount is that level which balances the marginal social beneift off against the marginal social cost.
