Creating a Learning Society

by Joseph E. Stiglitz

Joseph E. Stiglitz, professor of economics at Columbia University, and recipient of the 2001 Nobel Prize in Economics, is co-author, with Linda Bilmes, of The Three Trillion Dollar War: The True Costs of the Iraq Conflict.

NEW YORK – Citizens in the world’s richest countries have come to think of their economies as being based on innovation. But innovation has been part of the developed world’s economy for more than two centuries. Indeed, for thousands of years, until the Industrial Revolution, incomes stagnated. Then per capita income soared, increasing year after year, interrupted only by the occasional effects of cyclical fluctuations.

The Nobel laureate economist Robert Solow noted some 60 years ago that rising incomes should largely be attributed not to capital accumulation, but to technological progress – to learning how to do things better. While some of the productivity increase reflects the impact of dramatic discoveries, much of it has been due to small, incremental changes. And, if that is the case, it makes sense to focus attention on how societies learn, and what can be done to promote learning – including learning how to learn.

A century ago, the economist and political scientist Joseph Schumpeter argued that the central virtue of a market economy was its capacity to innovate. He contended that economists’ traditional focus on competitive markets was misplaced; what mattered was competition for the market, not competition in the market. Competition for the market drove innovation. A succession of monopolists would lead, in this view, to higher standards of living in the long run.

Schumpeter’s conclusions have not gone unchallenged. Monopolists and dominant firms, like Microsoft, can actually suppress innovation. Unless checked by anti-trust authorities, they can engage in anti-competitive behavior that reinforces their monopoly power.

Moreover, markets may not be efficient in either the level or direction of investments in research and learning. Private incentives are not well aligned with social returns: firms can gain from innovations that increase their market power, enable them to circumvent regulations, or channel rents that would otherwise accrue to others.

But one of Schumpeter’s fundamental insights has held up well: Conventional policies focusing on short-run efficiency may not be desirable, once one takes a long-run innovation/learning perspective. This is especially true for developing countries and emerging markets.

Industrial policies – in which governments intervene in the allocation of resources among sectors or favor some technologies over others – can help “infant economies” learn. Learning may be more marked in some sectors (such as industrial manufacturing) than in others, and the benefits of that learning, including the institutional development required for success, may spill over to other economic activities.

Such policies, when adopted, have been frequent targets of criticism. Government, it is often said, should not be engaged in picking winners. The market is far better in making such judgments.

But the evidence on that is not as compelling as free-market advocates claim. America’s private sector was notoriously bad in allocating capital and managing risk in the years before the global financial crisis, while studies show that average returns to the economy from government research projects are actually higher than those from private-sector projects – especially because the government invests more heavily in important basic research. One only needs to think of the social benefits traceable to the research that led to the development of the Internet or the discovery of DNA.

But, putting such successes aside, the point of industrial policy is not to pick winners at all. Rather, successful industrial policies identify sources of positive externalities – sectors where learning might generate benefits elsewhere in the economy.

Viewing economic policies through the lens of learning provides a different perspective on many issues. The great economist Kenneth Arrow emphasized the importance of learning by doing. The only way to learn what is required for industrial growth, for example, is to have industry. And that may require either ensuring that one’s exchange rate is competitive or that certain industries have privileged access to credit – as a number of East Asian countries did as part of their remarkably successful development strategies.

There is a compelling infant economy argument for industrial protection. Moreover, financial-market liberalization may undermine countries’ ability to learn another set of skills that are essential for development: how to allocate resources and manage risk.

Likewise, intellectual property, if not designed properly, can be a two-edged sword when viewed from a learning perspective. While it may enhance incentives to invest in research, it may also enhance incentives for secrecy – impeding the flow of knowledge that is essential to learning while encouraging firms to maximize what they draw from the pool of collective knowledge and to minimize what they contribute. In this scenario, the pace of innovation is actually reduced.

More broadly, many of the policies (especially those associated with the neoliberal “Washington Consensus”) foisted on developing countries with the noble objective of promoting the efficiency of resource allocation today actually impede learning, and thus lead to lower standards of living in the long run.

Virtually every government policy, intentionally or not, for better or for worse, has direct and indirect effects on learning. Developing countries where policymakers are cognizant of these effects are more likely to close the knowledge gap that separates them from the more developed countries. Developed countries, meanwhile, have an opportunity to narrow the gap between average and best practices, and to avoid the danger of secular stagnation.

EXTRACTS: "But property-sector woes are not the only economic danger China faces in 2021-22. The Chinese government’s mounting crackdown on the country’s burgeoning tech sector may pose an even greater threat." ---- "According to a recent study by McKinsey & Company, the share of Chinese urban employment supported by private enterprises more than quadrupled between 1995 and 2018, from just 18% to 87%. The share of exports generated by the private sector more than doubled over the same period, from 34% to 88%. And private-sector fixed-asset investment jumped from 42% to 65% of the total. The message in the data is clear: clamping down on the private sector and threatening innovators is not the way to ensure sustained rapid growth. Chinese entrepreneurs can read the writing on the wall. They understand that their political and regulatory room to maneuver is shrinking, and that the balance has shifted in favor of state-owned firms and public officials. And they understand that this uneasy atmosphere is likely to persist."

EXTRACT: "We designed a programme that incorporated data from over 300 million buildings and analysed 130 million km² of land – almost the entire land surface area of the planet. This estimated how much energy could be produced from the 0.2 million km² of rooftops present on that land, an area roughly the same size as the UK."

EXTRACT: "Britain in the 1950s was wedded to the US, acting as a partner rather than leading the charge. Now, while the UK continues to support the US, the influence it has seems negligible. While it may bring comfort to the UK to feel it is a partner to a superpower, being its stooge or subordinate is an unpleasant place to be, no matter how much you tell yourself it values your opinion."

EXTRACT: "That was then. Now, the Chinese government has doubled down, with President Xi Jinping throwing the full force of his power into a “common prosperity” campaign aimed at addressing inequalities of income and wealth. Moreover, the regulatory net has been broadened, not just to ban cryptocurrencies, but also to become an instrument of social engineering, with the government adding e-cigarettes, business drinking, and celebrity fan culture to its ever-lengthening list of bad social habits. All this only compounds the concerns I raised two months ago. The new dual thrust of Chinese policy – redistribution plus re-regulation – strikes at the heart of the market-based “reform and opening up” that have underpinned China’s growth miracle since the days of Deng Xiaoping in the 1980s. It will subdue the entrepreneurial activity that has been so important in powering China’s dynamic private sector, with lasting consequences for the next, innovations-driven, phase of Chinese economic development. Without animal spirits, the case for indigenous innovation is in tatters."

EXTRACT: "Wartime nostalgia plays an important part in Britain’s instinctive fondness for the special relationship. Like former Prime Minister Tony Blair in the run-up to the invasion of Iraq in 2003, some British politicians might believe that the United Kingdom is the only European country with serious armed forces and the political will to use them. Prime Minister Boris Johnson, like Blair before him, seems to fancy himself a modern-day Churchill. Unfortunately (or not), Britain’s military power is insignificant compared to what Churchill could command in 1944. Wartime nostalgia has drawn Britain into several foolish American wars, which other European countries were wise to avoid."

EXTRACTS: "We have found that 47 million American adults – nearly 1 in 5 – agree with the statement that “the 2020 election was stolen from Donald Trump and Joe Biden is an illegitimate president.” Of those, 21 million also agree that “use of force is justified to restore Donald J. Trump to the presidency.” Our survey found that many of these 21 million people with insurrectionist sentiments have the capacity for violent mobilization. At least 7 million of them already own a gun, and at least 3 million have served in the U.S. military and so have lethal skills. Of those 21 million, 6 million said they supported right-wing militias and extremist groups, and 1 million said they are themselves or personally know a member of such a group, including the Oath Keepers and Proud Boys." ----- "..... the Jan. 6 insurrection represents a far more mainstream movement than earlier instances of right-wing extremism across the country. Those events, mostly limited to white supremacist and militia groups, saw more than 100 individuals arrested from 2015 to 2020. But just 14% of those arrested for their actions on Jan. 6 are members of those groups. More than half are business owners or middle-aged white-collar professionals, and only 7% are unemployed."

EXTRACT: "That long path, though, has from the start had within it one fundamental flaw. If we are to make sense of wider global trends in insecurity, we have to recognise that in all the analysis around the 9/11 anniversary there lies the belief that the main security concern must be with an extreme version of Islam. It may seem a reasonable mistake, given the impact of the wars, but it still misses the point. The war on terror is better seen as one part of a global trend which goes well beyond a single religious tradition – a slow but steady move towards revolts from the margins."
Sep 11th 2021
EXTRACTS: "Is it not extraordinary that in a country that claims to be as enlightened and advanced as ours, the combined wealth of three individuals – Amazon founder Jeff Bezos, Microsoft founder Bill Gates, and investor Warren Buffett – exceeds the total wealth of the bottom half of Americans? One has to return to the days of the pharaohs of Egypt to find a parallel to the extreme wealth inequality that we see in in America today." ...... "The top tax rate remained above 90 percent through the 1950s and did not dip below 70 percent until 1981. At no point during the decades that saw America’s greatest economic growth did the tax on the wealthy drop below 70 percent. Today it is somewhere around 37 percent. President Biden’s American Families Plan would increase the top tax rate to 39.6 percent – a fairly modest alteration, albeit in the right direction. It is true that there was a time when the top marginal tax was even lower than it is today: in the years leading up to the Great Depression it hovered around 25 percent."
Sep 7th 2021
EXTRACT: "But Biden can’t be blamed for the rise of the Taliban, or the fragile state of a country that has seen far too many wars and invasions. The US should not have been there in the first place, but that is a lesson that great powers never seem to learn."
Sep 4th 2021
EXTRACT: "The world is only starting to grapple with how profound the artificial-intelligence revolution will be. AI technologies will create waves of progress in critical infrastructure, commerce, transportation, health, education, financial markets, food production, and environmental sustainability. Successful adoption of AI will drive economies, reshape societies, and determine which countries set the rules for the coming century." ----- "AI will reorganize the world and change the course of human history. The democratic world must lead that process."
Sep 1st 2021
EXTRACT: "Although the Fed is considering tapering its quantitative easing (QE), it will likely remain dovish and behind the curve overall. Like most central banks, it has been lured into a “debt trap” by the surge in private and public liabilities (as a share of GDP) in recent years. Even if inflation stays higher than targeted, exiting QE too soon could cause bond, credit, and stock markets to crash. That would subject the economy to a hard landing, potentially forcing the Fed to reverse itself and resume QE." ---- "After all, that is what happened between the fourth quarter of 2018 and the first quarter of 2019, following the Fed’s previous attempt to raise rates and roll back QE."
Sep 1st 2021
EXTRACT: "Today’s economic challenges are certainly solvable, and there is no reason why inflation should have to spike."
Aug 27th 2021
EXTRACT: "To be sure, they have focused on their agenda, which is totally misguided—not by our own account but by the account of the majority of the American population, who view the Republican party as one that has lost its moral footing to the detriment of America’s future generations, who must now inherit the ugly consequences of a party that ran asunder."
Aug 21st 2021
EXTRACTS: "Now that so many sad truths about Afghanistan are being spoken aloud, even in the major media – let me add one more: The war, from start to finish, was about politics, not in Afghanistan but in the United States. Afghanistan was always a sideshow."--- "....the 2001 invasion was fast and apparently decisive. And so it rescued George W. Bush’s tainted presidency,..." --- "Bush’s approval shot up to 90% and then steadily declined,..."
Aug 17th 2021
EXTRACT: "The Taliban’s virtually uncontested takeover over Afghanistan raises obvious questions about the wisdom of US President Joe Biden’s decision to withdraw US and coalition forces from the country. Paradoxically, however, the rapidity and ease of the Taliban’s advance only reaffirms that Biden made the right decision – and that he should not reverse course. ...... The ineffectiveness and collapse of Afghanistan’s military and governing institutions largely substantiates Biden’s skepticism that US-led efforts to prop up the government in Kabul would ever enable it to stand on its own feet. The international community has spent nearly 20 years, many thousands of lives, and trillions of dollars to do good by Afghanistan – taking down al-Qaeda; beating back the Taliban; supporting, advising, training, and equipping the Afghan military; bolstering governing institutions; and investing in the country’s civil society. .... Significant progress was made, but not enough." ....... "That is because the mission was fatally flawed from the outset. It was a fool’s errand to try to turn Afghanistan into a centralized, unitary state. "
Aug 6th 2021
EXTRACT: "But even in the US, which is more lenient than most countries, the principle cannot be absolute. Inciting imminent violence is not permitted. Donald Trump’s speech on January 6, urging the mob to storm the US Capitol, certainly came close to overstepping this boundary. It was a clear demonstration that language can be dangerous. What the internet media has done is raise the stakes; “fighting words” are spread around much faster and more widely than ever before. This will require a great deal of vigilance, to protect our freedom to express ourselves, while observing the social and legal bounds that stop words from turning into actual fighting. "
Jul 27th 2021
EXTRACT: "When it comes to the Chinese economy, I have been a congenital optimist for over 25 years. But now I have serious doubts. The Chinese government has taken dead aim at its dynamic technology sector, the engine of China’s New Economy. Its recent actions are symptomatic of a deeper problem: the state’s efforts to control the energy of animal spirits." ---- "... the Chinese economy, no less than others, still requires a foundation of trust – trust in the consistency of leadership priorities, in transparent governance, and in wise regulatory oversight – to flourish. --- Modern China lacks this foundation of trust ."
Jul 25th 2021
EXTRACT: "It seems that they are, as the last 18 months have seen a remarkable expansion of the central banks’ fields of activity, largely driven by their own ambitions. So they have moved into the climate change arena, arguing that financial stability may be put at risk by rising temperatures, and that central banks, as bond purchasers and as banking supervisors, can and should be proactive in raising the cost of credit for corporations without a credible transition plan. That is a promising new line of business, which is likely to grow. ---- Central banks are also trying to move into social engineering, specifically the policy response to rising income and wealth inequality, another hot button topic with high political salience."
Jul 25th 2021
EXTRACT: "The EU’s ambitious unilateral climate strategy will transform Europe into a trade fortress, encourage green protectionism worldwide, and give other regions the opportunity to develop using cheaper energy. And without China, India, and the United States on board, other countries will be careful not to follow the EU in its self-appointed role as the world’s green guinea pig. If Europe is not careful, it will risk finding itself in a climate club of one. "

EXTRACT: ".... ruminants belch and fart methane, an extremely potent greenhouse gas. As a result, rearing beef cattle brings about, on average, six times the contribution to global warming as non-ruminant animals (for example, pigs) producing the same quantity of protein. ..... if projected to 2050 [beef production], would use 87% of the total quantity of emissions that is compatible with the Paris climate agreement’s objective of staying below a 2° Celsius increase in temperature."
