How our emotional intelligence makes us productive

with one comment


Economists spend a lot of time investigating the factors that make people more productive. This is because more productive people – producing more, with less – is the reason we can today afford a much higher standard of living than our ancestors – in Africa, India or Europe – two centuries ago.

Many things improve our productivity. Technological improvements like a computer can allow us to use the power of machines to substitute manual labour. Education allow us to build faster and stronger computers. Both technology and education are key if we are to continue building and sharing a prosperous future.

But it is not only technology and education that improve our living standards. There are formal and informal institutions – things like the criminal-justice system, property right regimes and the political system – that create the incentives for us to invest in technology and education. And there are the even more softer things, like the way we make decisions (often referred to as ‘culture’), or our personalities. Economists are only now beginning to explore the roots of these ‘soft’ determinants.

Psychologists have known for long that our personality affect the way we make decisions. One example: Whether we apply for that senior position may depend on whether we exhibit the leadership qualities that is required to lead a large team. But what determines whether we have those leadership abilities? Is it nature or nurture?

One option is to look at siblings. If genetic traits (nature) were the only source of leadership qualities, then almost all the variation we find in society would be between families. In other words, there should be little variation between brothers, for example, as they have a lot of genetic overlap.

This is not the case, however, at least according to a recent NBER Working Paper written by three economists, Sandra Black, Björn Öckert and Erik Gröngqvist. Almost a third of total variation in personality traits, they note, are within the family. So, if it is not only nature that determine much of your personality, where do these within-family differences come from?

One possibility, they argue, is birth-order. Using a very rich Swedish dataset, the authors find that first-born children are ‘advantaged’ when measured on their ‘emotional stability, persistence, social outgoingness, willingness to assume responsibility and ability to take initiative’. Note: these are non-cognitive abilities, i.e. there is little difference in terms of a first-born and a third-born’s innate ability to do math, for example. It is on the softer abilities, instead, that first-borns clearly outperform their lower-ranked siblings: third-born children, for example, have non-cognitive abilities that are 0.2 standard deviations below first-born children.

These non-cognitive abilities matter. Controlling for many things, they show that first-born children are almost 30% more likely to be Top Managers compared to third-borns. This is because managerial positions, they argue, tend to require all Big Five domains of personality: openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability.

But why does birth-order matter? The authors argue for largely three possible reasons. First, biology. Successive children may have less of the stereotypical male behavioural traits due to the mother’s immunization to the H-Y antigen. But this seems unlikely to explain most of the variation, as the authors also find that birth order patterns vary depending on the sex composition of the older children: third-born sons perform worse on non-cognitive tests when their older siblings are male compared to when they are female.

This suggests that it has something to do with how parents allocate their time and resources, especially in the early years. ‘First-born children have the full attention of parents, but as families grow the family environment is diluted and parental resources become scarcer’, the authors argue. Parents may also have incentives for more strict parenting practices towards the first born to ensure a reputation for “toughness” necessary to induce effort among later born children.

Thirdly, children may also act strategically in competing for parental resources. Siblings compete for possession of property and access to the mother. Older siblings, research shows, tend to take a more dominant role in conflict and have more elaborate conflict strategies. To minimise conflict, parents tend to invest more in the dominant, older sibling.

Using a novel approach, the authors can identify which of these effects is largest. They find that biological factors only explain a small part, and may actually benefit later-born children. It is however in the behaviour of parents that there are distinct differences between first- and later-born children: they find that later-born children spend substantially less time on homework and more time watching TV. Parents are also less likely to discuss school work with later-born children, suggesting that it is the parents that lower their investment which explains the large gap in non-cognitive skills.

What the authors do not do is to link their results with the general improvement in living standards over the last two centuries. We are becoming ‘better angels of our nature’ because we grow up in smaller families with more parental attention and resources, improving our non-cognitive abilities.

It is not only the vast improvement in technology and education that has made us more productive, but also because we have become more conscientious, agreeable, responsible and willing to take the initiative. We are rich, in part, because we are more emotionally intelligent.

South Africa’s Great Leap Backward

with 4 comments

Great Leap Forward

Over the next few days, South Africa’s new Minister of Finance, Malusi Gigaba, will meet with representatives of the IMF, the World Bank, international investors, and ratings agencies in the US. His aim is to restore confidence, to steer the South African ship through the troubled waters of junk status.

This was a tough task a week ago, but his appointment of Chris Malikane, associate professor of Economics at Wits University, as adviser, has made this almost impossible. Malikane penned an 8-page manifesto early in April, which will apparently form the basis of his policy advice to Treasury. The document is available here: Chris Malikane – Concerning the Current Situation 2017. (Brace yourself: the phrase ‘white monopoly capital’ appears 58 times. The words ‘science’ or ‘innovation’, not once.)

I read the document just before I had to teach a class on China’s Great Leap Forward yesterday, and the similarities were startling. Malikane calls for the expropriation of ‘banks, insurance companies, mines and other monopoly industries, to industrialise the economy’. He wants to establish a state bank, nationalise the Reserve Bank, and ‘expropriate all land without compensation to the ownership of the state’. Oh, and he also wants ‘free, quality and decolonised education, free and quality healthcare, improved quality housing, community infrastructure, etc., affordable and safe public transport, and affordable and reliable basic services such as water, sanitation and electricity’.

An excellent Business Day editorial summed it up perfectly:

Malikane’s ideas are rooted in Marxist voodoo economics. For a finance minister to be taking advice from one with such outmoded and unorthodox ideas puts SA on the path towards such economic disasters as Zimbabwe and Venezuela. Doing so is an act of grotesque irresponsibility.

Just as we all borrow from banks to pay home loans, so South Africa borrows from international lenders to pay our expenses (which are more than our income, i.e. our budget deficit). If international investors do not believe we will be able to repay, they will make our loans more expensive by raising interest rates. It is not that these international investors want to exploit us – just as banks do not exploit us when we voluntarily go to them for loans – it is just that they want to make sure they get their money back. How an academic macroeconomist at one of South Africa’s top universities do not understand this, I do not know. One has to wonder what he teaches his students at Wits?

I hope the IMF, World Bank, investor and ratings agency representatives ask Gigaba about the economics of his new adviser. I hope they ask him what exactly Malikane will do in his capacity as adviser. I hope they ask him to state his own views about the market economy, about the interplay of fiscal and monetary policy, and, just for fun, about the role of Marxist economic thought in understanding international capital flows. And I hope they ask him whether he’s heard of China’s Great Leap Forward, and its consequences for the Chinese economy.*

Can private schools save South Africa?

with one comment


When I was an Economics student 12 years ago, the academic literature we read, by South Africa’s leading economic thinkers and social scientists, were lamenting the poor performance of the then South African school system. There was little doubt that what needed to happen was to improve the quality of the schools for the 80% South Africans who were still stuck, despite massive transfers of resources to these schools, in a system that had been crippled by apartheid-era policies.

Fast-forward to today.  A generation has now passed through the system, and there has been almost no improvement. Of 100 Grade 1-students that go to school, only 37 can hope to pass matric. With teacher trade unions opposing policies that might improve teacher quality, our Minister of Basic Education seems paralyzed. Corruption often means that budgets are either unspent or spent inefficiently. There is little hope that things will soon improve.

But there is an alternative. Over the last few years, private schools have become an alternative for middle-income families that want a better future for their children. Take Northern Academy in Polokwane, run by the JSE-listed Curro Group. Despite school fees that are around R21000 per year, with a similar amount for boarding, the school has more than 5000 students, 111 classrooms and 66 hostels. In the 2016 matric exams it was the top-performing independent school in the province.

Curro now has schools across all nine provinces. In the last four years, its share price has tripled. Its profit motive means that it must satisfy its client base: if it performs poorly by employing poorly-qualified teachers, its clients will go elsewhere. That is the miracle of the market-system that Adam Smith identified: profits are a way to signal that a firm is doing something right. If profits fall, the firm better improve its products or services or it will go out of business. If profits rise, like in the case of Curro, other firms will notice and enter the market, offering their own product and service which they hope will eat into the profits of the dominant firm.

One fear is that Curro will monopolise the market, charging fees that allow them to earn monopoly profits. This is unlikely in the education sector, though, as there are few barriers-to-entry. Consider the SPARK schools, with tuition also around R21000 per year, that have opened since 2013 in Gauteng and the Western Cape.

A second fear is that a well-run private school system will create further divisions in a country characterized by high levels of inequality; those that are able to afford the high school fees of good education will stand to benefit vis-à-vis kids from poor households forced to attend poor-quality public schools. This is likely to happen if private schools are limited to those that can afford to pay for them. But they need not be.

In Sweden, where equality-of-opportunity is almost a religion, more than 10% of kids are enrolled in private schools. A major education reform in 1992 allowed primary and secondary schools to receive public funding based on the number of students they have enrolled. These schools are not allowed to discriminate or require admissions exams, and they are not allowed to charge parents additional school fees. (They are allowed to accept donations, which are often used to expand school facilities or offer financial support for the poorest students.)

Anyone can start a for-profit school in Sweden. Many offer an alternative curriculum, or provide a service to international, religious or language groups. Others are designated sports or artistic schools. The point is simple: if a public school is not providing the services its community wants, an entrepreneur with the ability to identify a gap in the market will step in to deliver a better service.

This is what we need in South Africa too. The 2017 Budget allocated R243 billion to the Department of Basic Education, which is 16% of our total consolidated spending. With 11.2 million school-going kids in South Africa, that is slightly more than R21000 per kid.

What if every parent in South Africa received a government voucher of R21000 per student which they could deposit at any school they want, public or private? A larger amount could be given to those living in rural areas, and possibly those living in previously disadvantaged areas. This empowers parents to choose the schools which they believe will serve the interests of their kids best.

There are concerns with private education too, of course. One would want to make sure that facilities are of good quality, that teachers and curricula meet certain standards, and that there is some security that students’ interest will be served if a company that provides these services goes into liquidation. But those concerns pale in comparison to the atrocious outcomes of the current school system, where facilities are often non-existent and teachers unqualified.

Imagine the opportunities this will create for entrepreneurs. A community leader in an area with poor public schools can now take the initiative, appoint educators from within the community and use the vouchers to pay their salaries. Imagine Cricket South Africa partnering with an entrepreneur to build a chain of elite cricket schools, with CSA providing the facilities and coaches and the vouchers paying for high-quality education.

An important research literature suggests that mother-tongue education is critical for student success: with a voucher system, if there is a demand for secondary education in Sesotho in a specific community, expect an entrepreneur to spot the gap. Another concern for the near future is the dearth of university-trained teachers: private school chains will have an incentive to fix this, either by training their own teachers on the job, or by investing in teacher training colleges.

We need a new plan for education. I’d hate to see my colleagues 12 years from now write papers still lamenting the poor state of the South African education system. We keep throwing money at a problem that cannot be fixed by money alone. The Basic Education budget grew 7.3% in 2017. If we continue doing this, we are likely to fail a second post-apartheid generation.

How to get good politicians

leave a comment »

South African President Jacob Zuma visit Berlin

Politicians can shape the fortunes of countries. Presidents, in particular, set the tone: balancing many stakeholder interests, their job is to create a unifying vision that should guide policy-making. Members of parliament act upon this vision, designing and implementing policies that affect the lives of millions of people. One would imagine, then, that those with the best aptitude for leadership get elected.

That is the theory. But in practice politics is a messy business. For many reasons, it is often not the smartest candidate who gets elected, or the most effective member who gets selected for higher honours. Some economic models even explain why it is not the most capable that move up: Someone without a proper education (but a charismatic personality) has a much higher chance to see greater returns in politics than in the private sector. (In technical terms, lower opportunity costs give the less able a comparative advantage at entering public life.) These selection effects are compounded by the free-rider problem in politics, where work effort is not directly correlated to political outcomes. In other words, according to this model, it is society’s ‘chancers’ that are more likely to end up in politics – and the hard-working, smart ones will tend to end up in the private sector.

Competency in public office is, of course, is not the only goal of a parliamentary system. Representation – having politicians that reflect the demographic and geographic make-up of society-at-large – is also a key concern. But competency and representation, at least theoretically, do not always correlate. Take the following example: a proportional representation system, like we have in South Africa, would require members of all districts to be represented. But what if one region – let’s call it Farmville – has few university-trained citizens, whereas another region – Science City – has many citizens with university degrees? A proportional representation system will necessitate some Farmville politicians also be elected to parliament, even though the Science City politicians will probably be best qualified for the job. In contrast, in a plurality rule system – where the candidate with the most votes gets the job – competency often trumps representation.

A new NBER Working paper – Who Becomes a Politician? – by five Swedish social scientists, casts doubt on this trade-off. Using an extraordinarily rich dataset on the social background and competence levels of Swedish politicians and the general public, they show that an ‘inclusive meritocracy’ is an achievable goal, i.e. a society where competency and representation correlate in public office. They find that Swedish politicians are, on average, significantly smarter and better leaders than the population they represent. This, they find, is not because Swedish politicians are only drawn from the elite of society; in fact, the representation of politicians in Swedish municipalities, as measured by parental income or occupational class, is remarkably even. They conclude that there is at best a weak trade-off between competency and representation, mostly because there is ‘strong positive selection of politicians of low (parental) socioeconomic status.

These results are valid for Sweden, of course, which is a country unlike South Africa. Yet there are lessons that we can learn. First, what seems to matter is a combination of ‘well-paid full-time positions and a strong intrinsic motivation to serve in uncompensated ones’. In other words, a political party in South Africa that rewards hard work for those who serve in uncompensated positions, are likely to see the best leaders rise to the top, where they should be rewarded with market-related salaries. Second, an electoral system which allows parties to ‘represent various segments of society’. Political competition is good. Third, the ‘availability of talent across social classes’. This, they argue, is perhaps unique to Sweden, known for its universal high-quality education.

This reminded me of our State of the Nation red carpet event, where the cameras fixated on the gowns and glamour of South Africa’s political elite. How do the levels of competency in our parliament, I wondered, compare to Sweden and other countries?

Let’s just look at the top of the pyramid. The president of Brazil, Michel Temer, completed a doctorate in public law in 1974. He has published four major books in constitutional law. The Chinese president, Xi Jinping, also has a PhD in Law, although his initial field of study was chemical engineering. Narendra Modi, prime minister of India, has a Master’s degree in Political Science. Former US president Barack Obama graduated with a Doctor of Jurisprudence-degree magna cum laude from Harvard University. Angela Merkel, chancellor of Germany, has a PhD in quantum chemistry. Most of these widely respected leaders gave up a top job in the private sector or academe to pursue a political career.

Politics is messy, but given the right conditions, it can still attract high-quality leaders. For that to happen, though, aspiring politicians must put in the hard yards, even if initially uncompensated, supported by a competitive political party system and broad access to quality education. South Africa, unfortunately, is still a long way from meeting these criteria.

Four high-growth scenarios for Africa

leave a comment »


Can African countries sustain the relatively high growth rates they attained since 2000? At the start of 2017, putting aside the newsworthy political shifts and the fear of many that the developing world has entered a ‘secular stagnation’, this remains the most vexing question for those of us on the African continent.

It is not a question with an easy answer. The stellar economic performance of several African countries has created an ‘Africa rising’ narrative where further progress – and catch-up to the developed world – seems inevitable. A more pessimistic counternarrative argues that this growth, from a low base, is largely the result of favourable commodity prices and Chinese investment. Both narratives had, unfortunately, made little use of either economic theory or history.

Enter Dani Rodrik, professor of International Political Economy at the John F. Kennedy School of Government at Harvard University, who tackles this question in a new paper in the Journal of African Economies. He first shows that many African economies have indeed improved since 2000, but that many, including Senegal, the DRC, the Ivory Coast and Zambia, remain on levels below those immediately following colonialism (around 1960). The second fact he establishes is that the rapid growth of the last dozen years has not lead to a large structural transformation of the economy. Whereas rapid growth in south-east Asian economies during the late twentieth century resulted in the growth of manufacturing, a more productive activity than subsistence farming, high growth rates in Africa have not had any effect on the relative size of manufacturing. In fact, in many countries, the size of the manufacturing sector has actually declined since 1975.

Rodrik attributes these changes not so much to factors unique to Africa – like a poor business climate or weak institutions or bad geography – but to a global trend of deindustrialisation. Even Vietnam, a country which has recently experienced rapid growth, has not seen much growth in manufacturing.  And Latin American countries, which have decidedly better institutions than three decades ago, have also not seen much growth in manufacturing. Technological change – the move to automation, for example – is one likely reason.

So despite high growth rates, African countries have not industrialised – and, in fact, may have even begun to deindustrialise. This is why Rodrik is pessimistic about Africa’s future growth prospects. He nevertheless concludes by considering potential scenarios in which Africa can indeed sustain high growth, and identifies four possibilities: 1) To revive manufacturing and industrialise, 2) To generate agricultural-led growth, 3) To generate service-led growth and 4) To generate natural resource-led growth.

Let’s start with agriculture. Although many African countries have a lot of potential to expand their agricultural sectors, productivity in the agricultural sector remains low. Many farmers are subsistence producers, with low economies of scale. Such a scenario will require a reversal in the current trend away from agriculture. A recent study by Diao, Harttgen and McMillan show clearly how the share of agriculture is falling, particularly as women older than 25 are moving to the cities and into manufacturing and services. This trend seems irreversible, even if changes to technology (like seed varieties or market access opportunities) or institutions (like private property) are made, which means that an agricultural-led high growth scenario seems highly unlikely.

A natural resource-led strategy also seems unlikely for most African countries. Yes, most countries on the continent are well-endowed with resources, but the problems of the Natural Resource Curse and Dutch Disease are well known. It may be an option for some small economies, like Botswana has shown, but one has to question to what extent it can be sustainable beyond a certain level of income.

A third option is to reverse the trend of deindustrialisation. Because a growing manufacturing base seems to be, at least if we consider past examples of industrialisation, the only way to increase labour productivity over a sustained period of time, this is the option preferred by many development agencies. Yet there are many obstacles in the way of a thriving manufacturing sector, including poor infrastructure (transport and power in particular), red tape and corruption, low levels of human capital, and political and legal risk. But as explained earlier, Rodrik believes that even if these (very difficult) barriers can be overcome, it is not clear that manufacturing will return. The Fourth Industrial Revolution may completely alter the nature of manufacturing away from absorbing unskilled labour to capital and knowledge-intensive production. As I’ve said before, it is dangerous to follow a twentieth-century blueprint when production technologies are so different.

That leaves us with one scenario: services-led growth. Services have traditionally not acted as an ‘escalator sector’ as Rodrik explains. The problem is that services typically require high-skilled labourers, one thing that is in short supply in a developing economy. Rodrik does acknowledge, though, that the past will not necessarily look like the future. “Perhaps Africa will be the breeding ground of new technologies that will revolutionise services for broad masses, and do so in a way that creates high-wage jobs for all. Perhaps; but it is too early to be confident about the likelihood of this scenario.”

I don’t see an alternative, though. Yes, some countries, like Mozambique or Tanzania, will be able to expand their agricultural sectors – but higher productivity will probably mean larger farms with fewer workers. A few small countries will be able to benefit from natural resources – from diamonds to rare minerals like tantalum (used in cellphones and laptops); oil-producing countries will struggle, though, as the cost of renewable energies keeps falling. And some coastal countries may even develop their manufacturing sectors, like Ethiopia and South Africa. But for most of Africa, services offer the only reprieve from low productivity, low-wage jobs. From semi-skilled jobs like call-centres and virtual au pairs (apparently the next big thing) to professional services like accountants and designers and programmers, digital technologies must help leapfrog the barriers of poor infrastructure, bad geography and weak institutions. If it cannot, Dani Rodrik’s pessimistic vision of Africa’s future is likely to come true.

The world is not a zero-sum game, but it matters if you think it is

with 2 comments


Question: A farmer in your neighbourhood has had an exceptionally productive 2016. He has managed to double wheat output, and his favourite cow – Daisy – was awarded first prize in the national competition. What is the reason for the farmer’s success? Is it: a) He has worked very hard, b) He was lucky, or c) he put a spell on the rest of the farmers in his village?

This is an example of the type of survey questions a team of Harvard economists have been asking to subsistence farmers in the Democratic Republic of the Congo on several visits over the last few years. In contrast to what one might think, the answer to this question is almost always the same: C. Witchcraft and supernatural beliefs are widespread in Africa and throughout the developing world. One aim of the research group is to identify how these cultural traits affect economic decision-making. Clearly, if my answer to this question was that the farmer’s success was due to hard work, I would conclude that the way to excel is to work harder. But if my understanding is that this farmer somehow cheated – that his success was due to a spell he put on the rest of the community, and that his gain was our loss – then my takeaway is that I need to spend more of my surplus not on investing in my farm, but on bribing the local spiritual leader for favours.

The belief that the world is a zero-sum game is widespread. Like these Congolese farmers, many of us believe that the success of one member of our communities must be to the detriment of others. In some cases, this is, of course, true: when one bowler takes 7 wickets in an innings, it leaves only 3 scalps between the remaining bowlers. But, generally, the world is not zero-sum. China’s success is not a consequence of America’s decline, despite what the Trump propaganda machine says. Trade, as economists have known since David Ricardo, can be mutually beneficial, even if it means that the benefits and costs of growth are not shared by everyone equally. My neighbour’s financial success after she designed and marketed a new app is not the result of her ‘stealing’ my success.

But beliefs of a zero-sum world are widespread, and results in what has become known as the Tall Poppy Syndrome. I’ve seen this in action: students that excel sometimes draw the envy of their poorer-performing peers. And it has consequences: the envious ones believe that the good student must have achieved the high marks because of external factors, such as being the teachers’ favourite. They avoid taking responsibility for their own mediocre efforts. The star student, depending on the sanction of the envious ones, also reacts, either by withdrawing from social interaction or, worse, by putting in less effort in the next test to avoid standing out.

The Tall Poppy Syndrome is prevalent in all societies, but its density and effects are likely to vary. If TPS is more concentrated in poorer communities, for example, it will hamper social mobility, reinforcing both the poverty and the cultural beliefs itself. Development economists are therefore hoping to not only identify the causes of these beliefs but also how to change them.

This will not be easy: beliefs are difficult to measure accurately, and their origins may be deep in history. Nathan Nunn and Leonard Wantchekon’s work several years ago showed how the Atlantic slave trade still affects trust in African societies: people that today live in areas where most slaves were captured are more likely to distrust their neighbours and the government. In a new paper, Oded Galor and Ömer Özak show that people’s belief about time preference – whether you have a long-term horizon or not – were affected by what type of crops their ancestors grew. Both trust and time preferences are necessary ingredients for development. As Adam Smith already pointed out in the eighteenth century, trust is necessary for specialisation and exchange. A long-term horizon allows one to forego future income, invest in the present and earn the higher future returns. It affects our propensity to save, to adopt new technologies, and, as Galor and Özak show, even our likelihood to smoke.

If these cultural beliefs are so deeply rooted and have such a pervasive influence over our behaviour, what can be done to change them? This is difficult to answer and requires the interdisciplinary efforts of psychologists, economists, anthropologists and neuroscientists. The answers they provide may not only contribute to sustainable development and social mobility, but may have applications elsewhere. Marketers may have to design products that appeal to those with a zero-sum worldview, or managers may have to lead teams of people where some ascribe to this view. The incentives that motivate people who have Tall Poppy Syndrome, for example, are likely to be different to those who are less envious of their successful colleagues.

Our beliefs about the world shape our economic decision-making. We are only now beginning to understand how it does, and what to do to change it.

The future is an unknown unknown

leave a comment »


Humans know how to adapt. We have populated the planet not because we found an agreeable environment everywhere, but because we were able to adapt to the diverse and often hostile environments we moved into. And so it is today. To survive and thrive, we need to adapt to the global forces of our times, from climate change to automation.

Those with the freedom and ability to adapt to these global forces will benefit most. Take automation. Artificial intelligence and robotics now allow most tasks that manual labourers perform to be done without human intervention. One of the most exciting technologies revealed at the end of 2016, from my perspective at least, is an automated washing and ironing machine. Dirty clothes go in on one side and the fully-ironed clothes, folded by tiny robotic hands inside the machine, come out on the other side. Finally those dreary Sunday afternoon ironing exercises will be a thing of the past! Collectively this technology will save millions of productive human hours, particularly for women who in almost every society are still responsible for most home labour.

And yet, this wonderful new technology won’t be welcomed by everyone. South Africans employ more than 1 million domestic workers (or more than 8% of the work force), most of whom are women from poor households. If the cost of this new machine falls considerably in the next decade (and minimum wages continue to rise), we might soon see a significant decline in demand for ironing services. Because poor South Africans do not have the freedom to adapt to these new technologies, unemployment and inequality will likely increase.

There are many other examples. Tesla and other car companies are working on self-driving cars (no need for taxi drivers) and, which is likely to have an even bigger effect, self-driving buses. Truck driving is America’s sixth most common occupation. Or consider McDonald’s most recent innovation: self-ordering counters. No need to employ more expensive and unreliable staff. How long until everything in a McDonald’s restaurant is automated, from food preparation to servicing and cleaning? Amazon has recently revealed its plan to open 2000 automated grocery stores across the US. And then there are the many disruptive digital technologies, which The Economist editor Ryan Avent writes about in his latest book The Wealth of Humans.

The political consequences of these supersonic changes are unknown. As Avent notes, we are the first generation to live through an industrial revolution. There is little in history that tells us how society will react to such rapid changes. He predicts social unrest, unless government or civil society can reform social welfare programs on a massive scale. We have already seen this in South Africa and elsewhere: the democratic process, for many, is too slow and cumbersome. Service delivery protests, the #MustFall-movement and the global shift towards a more nativist conservatism suggest that the voices of those at the bottom of the income distribution will be heard outside the ballot box.

More creative solutions to support those left behind by the benefits of technological innovation and globalisation must be found. One idea is to institute a basic income grant that would give every person in South Africa a monthly stipend. This is no novel idea – Thomas Paine proposed a similar idea in 1797 – but economists are increasingly willing to put the idea in practice: Utrecht, a beautiful Dutch city south of Amsterdam, will next year give several hundred of its inhabitants an annual monthly stipend of 960 euro.

The concern is that people opt out of productive labour if they receive money for free. The consensus, though, is that this is unlikely: the aspirational drive of humans to move up the income ladder will push them to work hard regardless. What a basic income grant does is to make sure the ladder is solidly grounded.

But even a basic income grant won’t do enough. The rapid change will bring about psychological and sociological consequences that are hard to predict. Which social policies to implement, from early-childhood development to adult retraining programmes, in order to combat the technological disruption will be important research questions in the next few years. Creative use of technology, ironically, might be one solution.

Donald Rumsfeld famously quipped that there are known knows (the things we know we know), unknown knows (the things we know we don’t know), and unknown unknowns (the things we don’t know we don’t know). The future used to be mostly unknown knows. With some degree of likelihood, we could analyse the past and make conjectures, following somewhat linear trends, about what the future might hold. Change was incremental; we had time to adapt.

The period of rapid change we have seen since the dawn of the Internet is only likely to accelerate. As a species, we have never been required to adapt this fast, and not everyone in society will have the freedom and ability to do so. This will lead to social conflict. To minimise the consequences of this social conflict, the greatest challenge of the next decade is to enable as many as possible to adapt to the inevitable unknown unknowns of our rapidly-changing world.
