It is nearly 30 years since Rudiger Dornbusch and Sebastian Edwards published a seminal book, The Macroeconomics of Populism. Their conclusion back then was that the economic policies of populist leaders were quintessentially irresponsible. These governments, blinded by an aim to address perceived social injustices, specialised in profligacy, unbothered by budget constraints or whether they might run out of foreign exchange.

Because of this disregard for basic economic logic, their policy experiments inevitably ended badly, with some combination of inflation, capital flight, recession and default. Salvador Allende’s Chile in the 1970s, or Alan García’s Peru in the 1980s, capture this story perfectly.

These days, the macroeconomics of populism looks different. Of course there are populist leaders out there whose policies follow, more or less, the playbook of the 1970s and 1980s. Donald Trump may prove to be one of those, with a late-cycle fiscal expansion that seemed to have no basis in economic reasoning; Recep Tayyip Erdogan, by some accounts, may be another.

But a much more interesting phenomenon is the apparent surge in populist leaders whose economic policies are remarkably disciplined.

Take Mexico’s president, Andrés Manuel López Obrador. When it comes to fiscal policy, it is odd indeed that this fiery critic of neoliberalism seems fully committed to austerity. His budget for 2019 targets a surplus before interest payments of 1 per cent of GDP, and on current plans he intends to increase that surplus next year to 1.3 per cent of GDP. He has upheld the autonomy of the central bank and, so far at least, his overall macroeconomic framework is anything but revolutionary.

Hungary’s prime minister Viktor Orban offers another example of conservative populism. Under his watch, budget deficits have been considerably lower than they had been previously, helping to push the stock of public debt down from 74 per cent of GDP in 2010, the year Orban took over, to 68 per cent last year.

This emphasis on the virtues of fiscal prudence is also visible in Poland, where Jaroslaw Kaczynski’s PiS has managed public finances with sufficient discipline in the past few years to push the debt/GDP ratio below 50 per cent last year, the first time this has happened since 2009.

The obvious question is: what has changed in the decades since Dornbusch and Edwards went into print?

One answer is that today’s populists tend to strive for national self-reliance, which encourages them to avoid building up any dependence on foreign capital. And since that goal is achieved by keeping a tight rein on macro policy, fiscal indiscipline is avoided in order to limit vulnerability to foreign influences.

Perhaps this is because the 'them', or the perceived enemy, for many of today’s populists tends to be outside the country rather than inside. Broadly speaking, it is the forces of globalisation — and global capital in particular — that are the problem for these leaders, and self-reliance is the only way to keep those forces at arm’s length. This helps to explain why, for example, Orban has been so keen to repay debt to Hungary’s external creditors. He has relied instead on selling bonds to Hungarian households to finance his deficits, even though the interest rates on those bonds are much higher than he would pay to foreign creditors. It also helps explain why the PiS in Poland has presided over a decline in foreign holdings of its domestic bonds. Foreign investors owned 40 per cent of Poland’s domestic government debt back in 2015, but only 26 per cent now.

In other words, among many of today’s populists there is a blurring of the distinction between populism and nationalism. And the nationalistic urge to keep the rest of the world off your back seems to dominate the populist urge to spend money. The perfect example of that instinct is Vladimir Putin: not necessarily a populist, but his administration has been emphatic about the need to keep public spending low and to build solid financial buffers. National self-reliance is an economic obsession for the Russian government, and provides a model for other countries who wish to insulate themselves from international finance.

One of the reasons why the macroeconomics of populism have changed in this way is the historical legacy of economic disaster. If you are a populist leader in a country where financial crisis is part of living memory — as it is in Mexico, Hungary and Russia, say — you might do well to err on the side of conservatism for fear of repeating the mistakes of your predecessors.

But another reason why populism looks different for countries like Poland, Hungary, Mexico and Russia has to do with mere luck. Hungary and Poland, in particular, enjoy the luck of geography: having been absorbed into the EU, they have received financial transfers from Brussels averaging some 3-4 per cent of GDP in the past few years, so that populism in these countries has been solidly underpinned by the terms of their EU membership. López Obrador is enjoying the inheritance of his predecessor’s sound macro policy, together with a buoyant US economy and low US interest rates. Russia has had the good fortune of oil exports to rely on.

The thing about luck is that it can run out. So maybe it’s not quite time yet to bury the old macroeconomics of populism. But for the time being, it seems true to say that many of today’s populists have an unexpectedly robust sense of economic discipline.

The 2007-08 financial crisis wreaked havoc on the lives of millions of people across the globe, and upended the faith of many in the prevailing economic system, with many countries still recovering a decade on.

Drawing on extensive research in his new book, Narrative Economics: How Stories Go Viral and Drive Major Economic Events, Professor Shiller will draw on a rich array of historical examples and data and outline a new way to think about economic change, and the narratives that shape it, to provide answers to questions such as whether lessons have been learned since the last financial crisis, are the same dislocations likely to occur again and what toolkits, if any, are there for anticipating the next financial crisis or recession?

The renminbi seems to be back in business as a Chinese tool of retaliation against US tariffs. A 1.5 per cent fall in the currency early this month in response to proposed new US tariffs was only a start. Since the middle of August the renminbi has weakened further, and the exchange rate is now 4 per cent weaker than at the start of the month. We may well see more of a ‘weaponized’ renminbi, but there are four good reasons why Beijing might be wise to think before shooting.

The first has to do with how China seeks to promote its place in the world. China has been at pains to manage the collapse of its relations with the US in a way that allows it to present itself as an alternative pillar of global order, and as a source of stability in the international system, not to mention moral authority. This has deep roots.

Anyone investigating the history of Chinese statecraft will quickly come across an enduring distinction in Chinese thought: between wang dao, the kingly, or righteous way, and ba dao, the way of the hegemon. Since Chinese thinkers and officials routinely describe US behaviour since the Second World War as hegemonic, it behoves Chinese policymakers to do as much as possible to stay on moral high-ground in their behaviour towards Washington. Only in that way would President Xi be able properly to assert China’s claim to leadership.

Indeed, China has a notable track record of using exchange rate stability to enhance its reputation as a force for global stability. Both in the aftermath of the Asian crisis in 1997, and of the Global Financial Crisis in 2008, Chinese exchange rate stability was offered as a way of demonstrating China’s trustworthiness and its commitment to multilateral order.

Devaluing the renminbi in a meaningful way now might have a different rationale, but the cost to China’s claim to virtue, and its bid to offer itself as a guardian of global stability, might be considerable.

That’s particularly true because of the second problem China has in thinking about a weaker renminbi: it may not be all that effective in sustaining Chinese trade. One reason for this is the increasing co-movement with the renminbi of currencies in countries with whom China competes.

As the renminbi changes against the dollar, so do the Taiwan dollar, the Korean won, the Singapore dollar and the Indian rupee. In addition, the short-run impact of a weaker renminbi is more likely to curb imports than to expand exports, and so its effects might be contractionary. 

An ineffective devaluation of the renminbi would be particularly useless because of the third risk China needs to consider, namely the risk of retaliation by the US administration. Of this there is already plenty of evidence, of course.

The US Treasury’s declaration of China as a ‘currency manipulator’ on 5 August bears little relationship to the actual formal criteria that the Treasury uses to define that term, but equally the US had warned the Chinese back in May that these criteria don’t bind its hand. By abandoning a rules-based approach to the definition of currency manipulation, the US has opened wide the door to further antagonism, and Beijing should have no doubt that Washington will walk through that door if it wants to.

The fourth, and possibly most self-destructive, risk that China has to consider is that a weaker renminbi might destabilize China’s capital account, fuelling capital outflows that would leave China’s policymakers feeling very uncomfortable.

Indeed, there is already evidence that Chinese residents feel less confident that the renminbi is a reliable store of value, now that there is no longer a sense that the currency is destined to appreciate against the dollar. The best illustration of this comes from the ‘errors and omissions’, or unaccounted-for outflows, in China’s balance of payments.

The past few years have seen these outflows rise a lot, averaging some $200 billion per year during the past four calendar years, or almost 2 per cent GDP; and around $90 billion in the first three months of 2019 alone. These are scarily large numbers.

The risk here is that Chinese expectations about the renminbi are ‘adaptive’: the more the exchange rate weakens, the more Chinese residents expect it to weaken, and so the demand for dollars goes up. In principle, the only way to deal with this risk would be for the People's Bank of China (PBOC) to implement a large, one-off devaluation of the renminbi to a level at which dollars are expensive enough that no one wants to buy them anymore.

This would be very dangerous, though: it presupposes that the PBOC could know in advance the ‘equilibrium’ value of the renminbi. It would take an unusually brave central banker to claim such foresight, especially since that equilibrium value could itself be altered by the mere fact of such a dramatic change in policy.

No one really knows precisely by what mechanism capital outflows from China have accelerated in recent years, but a very good candidate is tourism. The expenditure of outbound Chinese tourists abroad has risen a lot in recent years, and that increase very closely mirrors the rise in ‘errors and omissions’. So the suspicion must be that the increasing flow of Chinese tourists – nearly one half of whom last year simply travelled to capital-controls-free Hong Kong and Macao – is just creating opportunities for unrecorded capital flight.

This raises a disturbing possibility: that the most effective way for China to devalue the renminbi without the backfire of capital outflows would be simultaneously to stem the outflow of Chinese tourists. China has form in this regard, albeit for differing reasons: this month it suspended a programme that allowed individual tourists from 47 Chinese cities to travel to Taiwan.

A more global restriction on Chinese tourism might make a devaluation of the renminbi ‘safer’, and it would have the collateral benefit of helping to increase China’s current account surplus, the evaporation of which in recent years owes a lot to rising tourism expenditure and which is almost certainly a source of unhappiness in Beijing, where mercantilism remains popular.

But a world where China could impose such draconian measures would be one where nationalism has reached heights we haven’t yet seen. Let’s hope we don’t go there.
