The Unreality of the “Real” Business Cycle

by Robert Skidelsky

Robert Skidelsky, a member of the British House of Lords, is Professor emeritus of political economy at Warwick University, author of a prize-winning biography of the economist John Maynard Keynes, and a board member of the Moscow School of Political Studies.

LONDON - Testifying recently before a United States congressional committee, former Federal Reserve Chairman Alan Greenspan said that the recent financial meltdown had shattered his "intellectual structure." I am keen to understand what he meant.

Since I have had no opportunity to ask him, I have to rely on his memoirs, The Age of Turbulence, for clues. But that book was published in 2007 - before, presumably, his intellectual structure fell apart.

In his memoirs, Greenspan revealed that his favorite economist was Joseph Schumpeter, inventor of the concept of "creative destruction." In Greenspan's summary of Schumpeter's thinking, a "market economy will incessantly revitalize itself from within by scrapping old and failing businesses and then reallocating resources to newer, more productive ones." Greenspan had seen "this pattern of progress and obsolescence repeat over and over again."

Capitalism advanced the human condition, said Schumpeter, through a "perennial gale of creative destruction," which he likened to a Darwinian process of natural selection to secure the "survival of the fittest." As Greenspan tells it, the "rougher edges" of creative destruction were legislated away by Franklin Roosevelt's New Deal, but after the wave of de-regulation of the 1970's, America recovered much of its entrepreneurial, risk-taking ethos. As Greenspan notes, it was the dot-com boom of the 1990's that "finally gave broad currency to Schumpeter's idea of creative destruction."

This was the same Greenspan who in 1996 warned of "irrational exuberance" and, then, as Fed chairman, did nothing to check it. Both the phrase and his lack of action make sense in the light of his (now shattered) intellectual system.

It is impossible to imagine a continuous gale of creative destruction taking place except in a context of boom and bust. Indeed, early theorists of business cycles understood this. (Schumpeter himself wrote a huge, largely unreadable book, with that title in 1939.)

In classic business-cycle theory, a boom is initiated by a clutch of inventions - power looms and spinning jennies in the eighteenth century, railways in the nineteenth century, automobiles in the twentieth century. But competitive pressures and the long gestation period of fixed-capital outlays multiply optimism, leading to more investment being undertaken than is actually profitable. Such over-investment produces an inevitable collapse.

Banks magnify the boom by making credit too easily available, and they exacerbate the bust by withdrawing it too abruptly. But the legacy is a more efficient stock of capital equipment.

Dennis Robertson, an early twentieth-century "real" business-cycle theorist, wrote: "I do not feel confident that a policy which, in the pursuit of stability of prices, output, and employment, had nipped in the bud the English railway boom of the forties, or the American railway boom of 1869-71, or the German electrical boom of the nineties, would have been on balance beneficial to the populations concerned." Like his contemporary, Schumpeter, Robertson regarded these boom-bust cycles, which involved both the creation of new capital and the destruction of old capital, as inseparable from progress.

Contemporary "real" business-cycle theory builds a mountain of mathematics on top of these early models, the main effect being to minimize the "destructiveness" of the "creation." It manages to combine technology-driven cycles of booms and recessions with markets that always clear (i.e., there is no unemployment).

How is this trick accomplished? When a positive technological "shock" raises real wages, people will work more, causing output to surge. In the face of a negative "shock," workers will increase their leisure, causing output to fall.

These are efficient responses to changes in real wages. No intervention by government is needed. Bailing out inefficient automobile companies like General Motors only slows down the rate of progress. In fact, whereas most schools of economic thought maintain that one of government's key responsibilities is to smooth the cycle, "real" business-cycle theory argues that reducing volatility reduces welfare!

It is hard to see how this type of theory either explains today's economic turbulence, or offers sound instruction about how to deal with it. First, in contrast to the dot-com boom, it is difficult to identify the technological "shock" that set off the boom. Of course, the upswing was marked by super-abundant credit. But this was not used to finance new inventions: it was the invention. It was called securitized mortgages. It left no monuments to human invention, only piles of financial ruin.

Second, this type of model strongly implies that governments should do nothing in the face of such "shocks." Indeed, "real" business-cycle economists typically argue that, but for Roosevelt's misguided New Deal policies, recovery from the Great Depression of 1929-1933 would have been much faster than it was.

Equivalent advice today would be that governments the world over are doing all the wrong things in bailing out top-heavy banks, subsidizing inefficient businesses, and putting obstacles in the way of rational workers spending more time with their families or taking lower-paid jobs. It reminds me of the interviewer who went to see Robert Lucas, one of the high priests of the New Business Cycle school, at a time of high American unemployment in the 1980's.

"My driver is an unemployed Ph.D. graduate," he said to Lucas. "Well, I'd say that if he is driving a taxi, he's a taxi-driver," replied the 1995 Nobel Laureate.

Although Schumpeter brilliantly captured the inherent dynamism of entrepreneur-led capitalism, his modern "real" successors smothered his insights in their obsession with "equilibrium" and "instant adjustments." For Schumpeter, there was something both noble and tragic about the spirit of capitalism. But those sentiments are a world away from the pretty, polite techniques of his mathematical progeny.

EXTRACT: "In contrast to the index for consumer goods, which measures only the prices of final products, industrial producer prices capture all intermediate stages of production. They therefore have a certain prognostic significance for consumer prices, even though the final products won’t show such extreme spikes. ----- These new inflation figures are so extreme that the ECB’s position looks like willful denial. Germany is currently experiencing the strongest inflation in a lifetime. And the situation is not much better in other European countries. In September, France reported an 11.6% annual increase in industrial producer prices, and that figure stood at 15.6% in Italy, 18.1% in Finland, 21.4% in the Netherlands, and 23.6% in Spain."

EXTRACT: "So it could well be that, despite the faster spread of the infection, its ultimate health, social and economic impact proves negligible. We simply do not know at this point. But detecting more uncertainty than before, financial markets have reacted with panic. For example, the S&P500 tumbled 2.3% on Friday November 26 only to rise 1.1% on Monday November 29. Most markets gave up between 2% and 4%, which is a pretty substantial one-day fall."
Nov 28th 2021
EXTRACT: "Momentous changes are casting a long shadow on China. The country’s political system will soon undergo a profound reform, pending final approval (a quasi-formality) at next year’s congress of the Communist Party of China (CPC). President Xi Jinping, the Party chairman and the “navigator” of the country, has decided on a new course, abandoning the principle of collective leadership. Xi is leading China away from the path taken by Deng Xiaoping after the terror of the Cultural Revolution, and back toward a system of absolute rule by one person without term limits, as under Mao Zedong."

EXTRACTS: "”The biggest disappointment in Glasgow was the last-minute watering down of the proposed (and widely supported) agreement to “phase out” the use of coal in energy production. With India providing political cover for China in vetoing this language, the final conference proposal was to “phase down” coal”. ---- “China accounts for more than half of the world’s coal consumption, and has the largest amount of coal-fired generating capacity under construction. Pressed about why his country would not do more in Glasgow to help save the planet, China’s chief negotiator pointed to the commitments in the Communist Party of China’s current Five-Year Plan. So, our future now depends on the CPC’s program. The tragedy for the world is that the Party cannot be phased down, much less phased out, despite the fact that it is a huge threat to the future of all of us.” ------ “To save the planet, robust democratic leadership must be phased up – not phased down, let alone phased out. Rather than merely keeping our fingers crossed and hoping for the best, we should start by calling out the appalling behavior of dictatorships such as China and Russia.”
Nov 22nd 2021
EXTRACT: "The transitory inflation debate in the United States is over. The upsurge in US inflation has turned into something far worse than the Federal Reserve expected. Perpetually optimistic financial markets are taking this largely in stride. The Fed is widely presumed to have both the wisdom and the firepower to keep underlying inflation in check. That remains to be seen."
Nov 14th 2021
EXTRACT: "S&P projects that companies are planning to install 44 gigawatts of new solar in 2022. The year 2020, despite the onset of the pandemic, saw a record-breaking 19 gigawatts of new solar capacity installed in the U.S. So given the bids out there already, it appears that in 2022 solar installers will more than double their best year ever so far. The U.S. currently has 100 gigawatts of solar electricity-generating capacity, so in just one year we are poised to add nearly 50% of our current total. A gigawatt of power can provide electricity to about 750,000 homes. So the 44 new gigawatts we’ll put in next year have a nameplate capacity that would under ideal conditions allow them to power 33 million homes." ----- "Not only is there a lot of good news on the green energy front but there is good news in the bad news for fossil fuels. S&P finds that coal plants are being retired way before the utilities had expected. Some 29 gigawatts of coal retirements are expected from 2020 through 2025. "
Nov 3rd 2021
EXTRACT: "Zemmour’s way of thinking stems from a tradition going back to the French Revolution of 1789. Catholic conservatives and right-wing intellectuals, who hated the secular republic that emerged from the revolution, have long fulminated against liberals, cosmopolitans, immigrants, and other enemies of their idea of a society based on ethnic purity, obedience to the church, and family values. They were almost invariably anti-Semitic. When Jewish army Captain Alfred Dreyfus was falsely accused of betraying his country in the notorious scandal of the 1890s, they were on the side of Dreyfus’s accusers. ---- Germany’s invasion of France in 1940 gave reactionaries of this kind the chance to form a French puppet-government in Vichy. Zemmour has had kind things to say about the Vichy regime. He also has expressed some doubt about the innocence of Dreyfus. ---- None of these views would be surprising if they came from a far-right agitator like Jean-Marie Le Pen. But Zemmour is the son of Sephardic Jewish immigrants from Algeria who lived among the Muslim Berbers."

EXTRACT: "performed strongly in last month’s parliamentary and regional elections. Officially, Communist Party candidates took 18.9% of the popular vote for the State Duma (parliament), compared to nearly 49.8% for the Kremlin’s United Russia party. But the Communists refused to recognize the results, insisting that the vote was rigged. And, indeed, some experts estimate that they should have gotten around 30% of the vote, with United Russia taking about 35%."

EXTRACT: "Powell was charismatic in the true sense of the term. Nowadays, this description is too often used to indicate an ability to attract supporters or generate celebrity interest. Internet lists of those who are regarded as charismatic include characters as varied as Adolf Hitler, Bono, Donald Trump, George Clooney, and Rihanna. But the ancient Greeks and Saint Paul used “charisma” to describe values-based leadership infused with a charm capable of inspiring devotion. The Greeks believed that this quality was a gift of grace, while Christian theology regarded it as a power given by the Holy Spirit."
Oct 17th 2021
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."
Oct 6th 2021
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."
Oct 6th 2021
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."
Oct 5th 2021
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."
Sep 24th 2021
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."
Sep 11th 2021
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."
