We’ve considered Keynesian economics and policy in several blogs. For example, a year ago in the post, What would Keynes say?, we looked at two articles arguing for Keynesian expansionary polices. More recently, in the blogs, End of the era of liquidity traps? and A risky dose of Keynesianism at the heart of Trumponomics, we looked at whether Donald Trump’s proposed policies are more Keynesian than his predecessor’s and at the opportunities and risks of such policies.
The article below, Larry Elliott updates the story by asking what Keynes would recommend today if he were alive. It also links to two other articles which add to the story.
Elliott asks his imaginary Keynes, for his analysis of the financial crisis of 2008 and of what has happened since. Keynes, he argues, would explain the crisis in terms of excessive borrowing, both private and public, and asset price bubbles. The bubbles then burst and people cut back on spending to claw down their debts.
Keynes, says Elliott, would approve of the initial response to the crisis: expansionary monetary policy (both lower interest rates and then quantitative easing) backed up by expansionary fiscal policy in 2009. But expansionary fiscal policies were short lived. Instead, austerity fiscal policies were adopted in an attempt to reduce public-sector deficits and, ultimately, public-sector debt. This slowed down the recovery and meant that much of the monetary expansion went into inflating the prices of assets, such as housing and shares, rather than in financing higher investment.
He also asks his imaginary Keynes what he’d recommend as the way forward today. Keynes outlines three alternatives to the current austerity policies, each involving expansionary fiscal policy:
||Trump’s policies of tax cuts combined with some increase in infrastructure spending. The problems with this are that there would be too little of the public infrastructure spending that the US economy needs and that the stimulus would be poorly focused.
||Government taking advantage of exceptionally low interest rates to borrow to invest in infrastructure. “Governments could do this without alarming the markets, Keynes says, if they followed his teachings and borrowed solely to invest.”
||Use money created through quantitative easing to finance public-sector investment in infrastructure and housing. “Building homes with QE makes sense; inflating house prices with QE does not.” (See the blogs, A flawed model of monetary policy and Global warning).
Increased government spending on infrastructure has been recommended by international organisations, such as the OECD and the IMF (see OECD goes public and The world economic outlook – as seen by the IMF). With the rise in populism and worries about low economic growth throughout much of the developed world, perhaps Keynesian fiscal policy will become more popular with governments.
Keynesian economics: is it time for the theory to rise from the dead?, The Guardian, Larry Elliott (11/12/16)
- What are the main factors determining a country’s long-term rate of economic growth?
- What are the benefits and limitations of using fiscal policy to raise global economic growth?
- What are the benefits and limitations of using new money created by the central bank to fund infrastructure spending?
- Draw an AD/AS diagram to illustrate the effect of a successful programme of public-sector infrastructure projects on GDP and prices.
- Draw a Keynesian 45° line diagram to illustrate the effect of a successful programme of public-sector infrastructure projects on actual and potential GDP.
- Why might an individual country benefit more from a co-ordinated expansionary fiscal policy of all countries rather than being the only country to pursue such a policy?
- Compare the relative effectiveness of increased government investment in infrastructure and tax cuts as alterative forms of expansionary fiscal policy.
- What determines the size of the multiplier effect of such policies?
- What supply-side policies could the government adopt to back up monetary and fiscal policy? Are the there lessons here from the Japanese government’s ‘three arrows’?
Here are two thought-provoking articles from The Guardian. They look at macroeconomic policy failures and at the likely consequences.
In first article, Larry Elliott, the Guardian’s Economics Editor, argues that Keynesian expansionary fiscal and monetary policy by the USA has allowed it to achieve much more rapid recovery than Europe, which, by contrast, has chosen to follow fiscal austerity policies and only recently mildly expansionary monetary policy through a belated QE programme.
In the UK, the recovery has been more significant than in the eurozone because of the expansionary monetary policies pursued by the Bank of England in its quantitative easing programme. ‘And when it came to fiscal policy, George Osborne quietly abandoned his original deficit reduction targets when the deleterious impact of an over-aggressive austerity strategy became apparent.’
So, according to Larry Elliott, Europe should ease up on austerity and governments should invest more though increased borrowing.
‘This is textbook Keynesian stuff. Unemployment is high, which means businesses are reluctant to invest. The lack of investment means that demand for new loans is weak. The weakness of demand for loans means that driving down the cost of borrowing through QE will have little impact. Therefore, it is up to the state to break into the vicious circle by investing itself, something it can do cheaply and – because there are so many people unemployed and businesses working well below full capacity – without the risk of inflation.’
In the second article, Paul Mason, the Economics Editor at Channel 4 News, points to the large increases in both public- and private- sector debt since 2007, despite the recession. Such debt, he argues, is becoming unsustainable and hence the world could be on the cusp of another crash.
Mason quotes from the Bank for International Settlements Quarterly Review September 2015 – media briefing. In this briefing, Claudio Borio,
Head of the Monetary & Economic Department, argues that:
‘Since at least 2009, domestic vulnerabilities have developed in several emerging market economies (EMEs), including some of the largest, and to a lesser extent even in some advanced economies, notably commodity exporters. In particular, these countries have exhibited signs of a build-up of financial imbalances, in the form of outsize credit booms alongside strong increases in asset prices, especially property prices, supported by unusually easy global liquidity conditions. It is the coincidence of the reversal of these booms with external vulnerabilities that should be watched most closely.’
We have already seen a fall in commodity prices, reflecting the underlying lack of demand, and large fluctuations in stock markets. The Chinese economy is slowing markedly, as are several other EMEs, and Europe and Japan are struggling to recover, despite their QE programmes. The USA is no longer engaging in QE and there are growing worries about a US slowdown as growth in the rest of the world slows. Mason, quoting the BIS briefing, states that:
‘In short, as the BIS economists put it, this is “a world in which debt levels are too high, productivity growth too weak and financial risks too threatening”. It’s impossible to extrapolate from all this the date the crash will happen, or the form it will take. All we know is there is a mismatch between rising credit, falling growth, trade and prices, and a febrile financial market, which, at present, keeps switchback riding as money flows from one sector, or geographic region, to another.’
So should there be more expansionary policy, or should rising debt levels be reduced by tighter monetary policy? Read the articles and then consider the questions.

Apocalypse now: has the next giant financial crash already begun? The Guardian, Paul Mason (1/11/15)
- To what extent do the two articles (a) agree and (b) disagree?
- How might a neo-liberal economist reply to the argument that what is needed is more expansionary fiscal and monetary policies?
- What is the transmission mechanism whereby quantitative easing affects real output? Is it a reliable mechanism for policymakers?
- What would make a financial crash less likely? Is this something that governments or central banks can influence?
- Why has productivity growth been so low in many countries? What would increase it?
The rate of growth in India has fallen to its lowest level since the first three months of 2009 – the period when many countries were plunging into recession. Although the annual rate was still 4.4% in Q2 2013 (a rate most Western governments would love to achieve!), it had averaged 8.2% from 2003 to 2007 and 9.5% from 2010 to 2011 (see).
And the rupee has been falling in value (see chart below). The exchange rate of the rupee to the dollar has depreciated by 21% since the start of the year and by 14% since the beginning of August (click here for a PowerPoint of the chart). This has pushed up the price of imports and raised fears that inflation, already approaching 10%, will rise.
There have also been concerns about the health of India’s banking sector, with worries over the possible rise in bad loans.
One result of all these factors is that the confidence of investors has been shaken. Bond prices have fallen and so too have share prices. The Mumbai Sensex index fell by 11.5% from 22 July to 27 August. Worried about possible capital flight, the Indian government imposed capital controls on Indian residents on 14 August. It has, however, since ruled out limiting the outflow of funds by foreign investors.

An excellent learning exercise for students of economics is to take a journal article that uses data to model the economy and then try to replicate the authors’ results. You may well be given an assignment like this in future years of your degree.
One such exercise is used on the University of Massachusetts Amherst’s doctoral programme in economics. Thomas Herndon is a student on that degree and chose to examine a well-known and highly influential paper, Growth in a Time of Debt by Carmen Reinhart then of the University of Maryland and Kenneth Rogoff of Harvard University and former chief economist of the IMF. Professors Reinhart and Rogoff used new data on 44 countries spanning about 200 years.
A key finding of their paper, published in 2010 in the American Economic Review Papers and Proceedings, is that once a country’s government debt exceeds 90% of GDP, growth rates fall considerably: the median across countries by about 1% and the mean considerably more.
The paper has been hugely influential. It has been used to justify the austerity programmes being pursued in many countries, including the UK and the eurozone. Cutting the government deficit to GDP ratio, and ultimately the government debt to GDP ratio, has been seen as a way of achieving higher growth over the longer term, and justifies the adverse effect on short-term growth from the dampening of aggregate demand.
Well, this seemed an interesting paper for Thomas Herndon to examine, and he was keen to show just how Reinhart and Rogoff’s data led to their conclusions. But try as he might, he could not replicate their results. His initial reaction was to think he had made an error, but each time he checked he came back with the same conclusion: they must have made errors in their calculations.
His supervisor at Amherst, Professor Michael Ash, after Thomas had checked and checked again, realised that something was wrong. He encouraged Thomas to write to Reinhart and Rogoff to request sight of their dataset. They duly obliged and it was then that Thomas spotted various errors. These are explained in the articles below, but the overall effect was to alter the conclusion. Although high debt may undermine growth to some extent, the effect is much less than Reinhart and Rogoff concluded, and there are several exceptions to this rule.
On 15 April 2013, Thomas, along with his supervisor, Michael Ash and his colleague, Robert Pollin, published a response to the Reinhart and Rogoff paper. In the abstract to their paper, Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogoff they state that:
… coding errors, selective exclusion of available data, and unconventional weighting of summary statistics lead to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the post-war period. They find that when properly calculated, the average real GDP growth rate for countries carrying a public-debt-to-GDP ratio of over 90 percent is actually 2.2 percent, not –0:1 percent as published in Reinhart and Rogoff. That is, contrary to RR, average GDP growth at public debt/GDP ratios over 90 percent is not dramatically different than when debt/GDP ratios are lower.
The authors also show how the relationship between public debt and GDP growth varies significantly by time period and country. Overall, the evidence we review contradicts Reinhart and Rogoff’s claim to have identified an important stylized fact, that public debt loads greater than 90 percent of GDP consistently reduce GDP growth.
So could this be you in the future? Will you take a famous paper and, by re-examining and reworking the data, find that its conclusions are wrong? Could you end up changing the world? Exciting stuff!

- What were the particular errors made by Reinhart and Rogoff?
- How has their paper been used as a basis for the design of macroeconomic policy?
- What are the limitations of using even accurate time-series data as the basis for policy measures?
- How might the work of Herndon change the direction of future macroeconomic policy?
- In his guest post in Business Insider (see link above), Herndon wrote: ‘The implication for policy is that, under particular circumstances, public debt can play a key role in overcoming a recession.’ What might this role be?
- Why might we have to be cautious in drawing policy conclusions from Herndon’s work?
What lies ahead for economic growth in 2013 and beyond? And what policies should governments adopt to aid recovery? These are questions examined in four very different articles from The Guardian.
The first is by Nouriel Roubini, Professor of Economics at New York University’s Stern School of Business. He was one of the few economists to predict the collapse of the housing market in the USA in 2007 and the credit crunch and global recession that followed. He argues that continuing attempts by banks, governments and individuals to reduce debt and leverage will mean that the advanced economies will struggle to achieve an average rate of economic growth of 1%. He also identifies a number of other risks to the global economy.
In contrast to Roubini, who predicts that ‘stagnation and outright recession – exacerbated by front-loaded fiscal austerity, a strong euro and an ongoing credit crunch – remain Europe’s norm’, Christine Lagarde, head of the IMF and former French Finance Minister, predicts that the eurozone will return to growth. ‘It’s clearly the case’, she says, ‘that investors are returning to the eurozone, and resuming confidence in that market.’ Her views are echoed by world leaders meeting at the World Economic Forum in Davos, Switzerland, who are generally optimistic about prospects for economic recovery in the eurozone.
The third article, by Aditya Chakrabortty, economics leader writer for The Guardian, looks at the policies advocated at the end of World War II by the Polish economist, Michael Kalecki and argues that such policies are relevant today. Rather than responding to high deficits and debt by adopting tough fiscal austerity measures, governments should adopt expansionary fiscal policy, targeted at expanding infrastructure and increasing capacity in the economy. That would have an expansionary effect on both aggregate demand and aggregate supply. Sticking with austerity will result in continuing recession and the ‘the transfer of wealth and power into ever fewer hands.’
But while in the UK and the eurozone austerity policies are taking hold, the new government in Japan is adopting a sharply expansionary mix of fiscal and monetary policies – much as Kalecki would have advocated. The Bank of Japan will engage in large-scale quantitative easing, which will become an open-ended commitment in 2014, and is raising its inflation target from 1% to 2%. Meanwhile the Japanese government has decided to raise government spending on infrastructure and other government projects.
