Policymakers and too many economic commentators fail to grasp how the next global recession may be unlike the last two. In contrast to recessions driven mainly by a demand shortfall, the challenge posed by a supply-side-driven downturn is that it can result in sharp drops in production, generalized shortages, and rapidly rising prices.

The COVID-19 epidemic’s tail risks are significant and frightening, but as of now, they do not seem particularly likely to materialize. Instead, the outbreak’s economic consequences will probably be substantial but transitory.

The world is going through a period of accelerating change, as four secular developments illustrate. Firms and governments must make timely adjustments, not only to their business models and operational approaches, but also to both their tactical and strategic mindsets.

Financial markets remain blissfully in denial of the many predictable global crises that could come to a head this year, particularly in the months before the US presidential election. In addition to the increasingly obvious risks associated with climate change, at least four countries want to destabilize the US from within.

All strategies to mitigate climate change have distributive implications that cannot be overlooked. If left unaddressed, such implications will fuel persistent headwinds to progress on the climate change and sustainability agenda.

Many leading central bankers now argue that, instead of just playing its traditional role of deciding the allocation of government spending, investment, taxes, and transfers, fiscal policy must substitute for monetary policy in economic fine-tuning and fighting recession. That would be a big mistake.

The Trump administration's unilateral approach to trade and foreign adversaries like Iran is reminiscent of the Reagan administration's strategy against the Soviet Union. Both game theory and the historical record show that aggressive "non-cooperation" can be effective, but only if it is used carefully.

A restrained reprisal by Iran following the assassination of its top military commander has led markets to conclude that the latest threat to the global economy has been removed. But just because Iran and the United States have so far avoided a full-scale war does not mean that markets are out of the woods.

After committing to monetary-policy normalization in 2018, the US Federal Reserve and the European Central Bank spent the past year reversing course with further interest-rate cuts and liquidity injections. Yet, given mounting medium-term uncertainties, central bankers cannot assume calm conditions in 2020.

The scientific evidence increasingly indicates that the world may soon reach a point of no return regarding climate change. So, rather than worrying almost exclusively about economic and political inequality, rich-country citizens need to start thinking about how to deal with global energy inequality before it’s too late.

At the start of a new year and a new decade, it is both humbling and illuminating to reflect on major global developments that no one saw coming just a few decades ago. For those who grew up during the Cold War or in the ensuing period of American primacy, the economic and geopolitical rise of the developing world must rank high on the list.

With the United Kingdom’s withdrawal from the European Union now set to take effect on January 31, 2020, the most important challenge facing UK Prime Minister Boris Johnson is negotiating his country's new relationship with the bloc. He has every incentive to keep that process as non-controversial as possible.

It doesn't take much to spark corrections in vulnerable economies and markets, and big shocks to highly vulnerable systems are a recipe for crisis. That's why the vulnerability of today's global economy – reflected in real economies, financial asset prices, and misguided monetary policy – needs to be taken seriously.

Despite the latest Sino-American "skinny deal" to ease tensions over trade, technology, and other issues, it is now clear that the world's two largest economies have entered a new era of sustained competition. How the relationship will evolve depends greatly on America's political leadership – which does not bode well.

Compared to this time last year, the prospects for markets and the global economy heading into 2020 are surprisingly bright. But look further ahead and you will encounter deep uncertainty, suggesting that policymakers around the world would do well to implement inclusive-growth policies sooner rather than later.

With borrowing costs at multi-decade lows, governments seemingly can take on much more debt without any great concern about long-term consequences. But the real risks and costs of higher public borrowing may be hidden.

If Boris Johnson wins the United Kingdom's upcoming vote, as expected, Brexit will go ahead and cause the country long-term damage. But for the next several years, almost nothing about the UK's relationship with the European Union is likely to change, because Johnson can – and almost certainly will – extend the transition period.

Writing in the 1830s, as the Industrial Revolution gathered pace, Honoré de Balzac anticipated the broader social concern: “The secret of great fortunes without apparent cause is a crime that has been forgotten, because it was properly carried out.” But today's billionaires make forgetting impossible.

Trade truce or not, a protracted Cold War-like conflict between the United States and China has already begun. That should worry the US, which, unlike China, is devoid of a long-term strategic framework.

Owing to a recent easing of both Sino-American tensions and monetary policies, many investors seem to be betting on another era of expansion for the global economy. But they would do well to remember that the fundamental risks to growth remain, and are actually getting worse.

These days, the International Monetary Fund’s policy recommendations – especially as they pertain to the advanced economies – have little impact. Although this is partly a consequence of more inward-looking national politics in richer countries, the Fund itself is not blameless.

Facebook CEO Mark Zuckerberg was at least half right when he recently told the United States Congress that there is no US monopoly on regulation of next-generation payments technology.

The US Federal Reserve is right to be concerned, if not worried, about the greenback's dominance of international trade and finance. Fortunately for consumers, growing potential competitive pressure – call it the Libra effect – creates an incentive to make the existing system work better.

For 40 years, elites in rich and poor countries alike promised that neoliberal policies would lead to faster economic growth, and that the benefits would trickle down so that everyone, including the poorest, would be better off. Now that the evidence is in, is it any wonder that trust in elites and confidence in democracy have plummeted?

Central bankers have been the first to recognize that the effectiveness of monetary policy in managing demand and stabilizing economic cycles has reached its limits. The problem is that many politicians and academic economists remain in denial.

Steadily rising income and wealth inequality, along with declining social mobility, is contributing to political polarization. Fortunately, If there is growing demand for some type of tax-policy response to the problem, we have ways to determine which measures would be most effective, depending on the specific objective.

With the global economy experiencing a synchronized slowdown, any number of tail risks could bring on an outright recession. When that happens, policymakers will almost certainly pursue some form of central-bank-financed stimulus, regardless of whether the situation calls for it.

Despite the severity of the climate-change crisis, much of the debate in advanced economies is entirely inward-looking, without recognizing that the real growth in carbon dioxide emissions is coming from emerging Asia. In fact, Asia already accounts for a higher share of global emissions than the United States and Europe combined.

It’s high time to ask how to refocus the International Monetary Fund’s mandate for dealing with emerging-market debt crises. How can the IMF be effective in helping countries regain access to private credit markets when any attempt to close unsustainable budget deficits is labeled austerity?

Despite all the lurid headlines about the trade war causing a recession in the United States or some kind of collapse in China and its Asian neighbors, recent economic data reveal a very different picture: the main victim has been Europe. But, fortunately for the European economy, overdependence on foreign trade is not the whole story.

The eurozone economy urgently needs a more comprehensive pro-growth policy approach at both the national and regional levels, or else a second lost decade will be all but assured. Hope for the continent now rests squarely on the shoulders of Christine Lagarde, the highly accomplished incoming president of the European Central Bank.

Between US President Donald Trump's zero-sum disputes with China and Iran, UK Prime Minister Boris Johnson's brinkmanship with Parliament and the European Union, and Argentina's likely return to Peronist populism, the fate of the global economy is balancing on a knife edge. Any of these scenarios could lead to a crisis with rapid spillover effects.

There is a reason that the US Federal Reserve chair often has a haunted look. Probably to his deep and never-to-be-expressed frustration, the Fed is setting monetary policy in a way that increases the likelihood that President Donald Trump will be reelected next year.

With a presidential election approaching next month, Argentina is once again on the cusp of a crisis that could end in depression and default, owing to mistakes made by everyone involved. Should President Mauricio Macri secure another term, he must waste no time in reversing the country's economic deterioration.

Supporters of Modern Monetary Theory say that some governments can easily cover the cost of large social programs such as health care for all and free college tuition by jettisoning conventional thinking about the role of debt and taxes in our economies. But is it really that simple?

Many economists already favor a consumption-based tax system for raising revenue on grounds of efficiency and simplicity. In an environment where wealth inequality is rising inexorably, the case for doing so has become increasingly compelling.

So far, with his flashy lifestyle, the US president has been a resounding inspiration to many consumers and investors. But his personal narrative is unlikely to survive an economic downturn, because people pull back during such periods and reassess their views and the stories they find believable.

The recent decision by America's Business Roundtable to abandon its support for shareholder primacy was a long time coming, and reflects a broader shift toward socially conscious investment. Now that the multi-stakeholder model is receiving the attention it deserves, it will be incumbent on governments to create space for it to succeed.

In an environment of secular stagnation in the developed economies, central bankers’ ingenuity in loosening monetary policy is exactly what is not needed. What is needed are admissions of impotence, in order to spur efforts by governments to promote demand through fiscal policies and other means.

Unlike the 2008 global financial crisis, which was mostly a large negative aggregate demand shock, the next recession is likely to be caused by permanent negative supply shocks from the Sino-American trade and technology war. And trying to undo the damage through never-ending monetary and fiscal stimulus will not be an option.

US President Donald Trump wants to compress the United States trade deficit and enhance the competitiveness of domestic manufacturers by using tariffs to raise the price of imported goods. And the fixed exchange rates he needs to achieve that goal are the real reason behind his nomination of Judy Shelton to the Federal Reserve Board.

Trade tensions are a symptom rather than a cause of the world’s underlying economic and financial malaise. Moreover, an excessive focus on trade could deflect policymakers’ attention from other measures needed to ensure faster and more inclusive growth in a genuinely stable financial environment.

Markets are mechanisms of social choice, in which dollars effectively equal votes; those with more purchasing power thus have more influence over market outcomes. Governments are also social choice mechanisms, but voting power is – or is supposed to be – distributed equally, regardless of wealth.

Political betting markets now put the chance of a no-deal Brexit at roughly one-third. But, regardless of the reckless promises to Conservative Europhobes that made Boris Johnson prime minister, an orderly, negotiated Brexit will be the favored option for a political libertine whose only consistent principle has been inconsistency.

Following the 2008 global financial crisis, central banks bet that greater activism on the part of other policymakers would be their salvation, helping them to normalize their operations. But that activism never came, and central bankers are now facing a lose-lose proposition.

Cryptocurrencies have given rise to an entire new criminal industry, comprising unregulated offshore exchanges, paid propagandists, and an army of scammers looking to fleece retail investors. Yet, despite the overwhelming evidence of rampant fraud and abuse, financial regulators and law-enforcement agencies remain asleep at the wheel.

While having a president with specialized training as a monetary economist would benefit the European Central Bank, such training is not essential. If Christine Lagarde is confirmed for the position, Europe will learn that other attributes matter much more.

To the dismay of many energy experts, the World Bank recently rather capriciously decided to stop funding virtually all new fossil-fuel plants. But phasing out readily available coal is a move that most major developing countries simply cannot afford without adequate incentives.

Only a fool would trust Facebook with his or her financial wellbeing. But maybe that’s the point: with so much personal data on some 2.4 billion monthly active users, who knows better than Facebook just how many suckers are born every minute?

Many economists have become convinced that a recession in the United States is now overdue, if not immediately then surely before the 2020 presidential election. But US recessions since the end of World War II have generally resulted from three causes, none of which is currently present.
