What would Keynes say if he were alive today?

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.

A risky dose of Keynesianism at the heart of Trumponomics

The first article below, from The Economist, examines likely macroeconomic policy under Donald Trump. He has stated that he plans to cut taxes, including reducing the top rates of income tax and reducing taxes on corporate income and capital gains. At the same time he has pledged to increase infrastructure spending.

This expansionary fiscal policy is unlikely to be accompanied by accommodating monetary policy. Interest rates would therefore rise to tackle the inflationary pressures from the fiscal policy. One effect of this would be to drive up the dollar and therein lies significant risks.

The first is that the value of dollar-denominated debt would rise in foreign currency terms, thereby making it difficult for countries with high levels of dollar debt to service those debts, possibly leading to default and resulting international instability. At the same time, a rising dollar may encourage capital flight from weaker countries to the US (see The Economist article, ‘Emerging markets: Reversal of fortune’).

The second risk is that a rising dollar would worsen the US balance of trade account as US exports became less competitive and imports became more so. This may encourage Donald Trump to impose tariffs on various imports – something alluded to in campaign speeches. But, as we saw in the blog, Trump and Trade, “With complex modern supply chains, many products use components and services, such as design and logistics, from many different countries. Imposing restrictions on imports may lead to damage to products which are seen as US products”.

The third risk is that the main beneficiaries of Trump’s likely fiscal measures will be the rich, who would end up paying significantly less tax. With all the concerns from poor Americans, including people who voted for Trump, about growing inequality, measures that increase this inequality are unlikely to prove popular.

Brazil: suffering from an old economic problem in the new world

The article below looks at the economy of Brazil. The statistics do not look good. Real output fell last year by 3.8% and this year it is expected to fall by another 3.3%. Inflation this year is expected to be 9.0% and unemployment 11.2%, with the government deficit expected to be 10.4% of GDP.

The article considers Keynesian economics in the light of the case of Brazil, which is suffering from declining potential supply, but excess demand. It compares Brazil with the case of most developed countries in the aftermath of the financial crisis. Here countries have suffered from a lack of demand, made worse by austerity policies, and only helped by expansionary monetary policy. But the effect of the monetary policy has generally been weak, as much of the extra money has been used to purchase assets rather than funding a growth in aggregate demand.

Different policy prescriptions are proposed in the article. For developed countries struggling to grow, the solution would seem to be expansionary fiscal policy, made easy to fund by lower interest rates. For Brazil, by contrast, the solution proposed is one of austerity. Fiscal policy should be tightened. As the article states:

Spending restraint might well prove painful for some members of Brazilian society. But hyperinflation and default are hardly a walk in the park for those struggling to get by. Generally speaking, austerity has been a misguided policy approach in recent years. But Brazil is a special case. For now, anyway.

The tight fiscal policies could be accompanied by supply-side policies aimed at reducing bureaucracy and inefficiency.

Relaxing the inflation target

The Bank of England’s monetary policy is aimed at achieving an inflation rate of 2% CPI inflation ‘within a reasonable time period’, typically within 24 months. But speaking in Nottingham in one of the ‘Future Forum‘ events on 14 October, the Bank’s Governor, Mark Carney, said that the Bank would be willing to accept inflation above the target in order to protect growth in the economy.

“We’re willing to tolerate a bit of an overshoot in inflation over the course of the next few years in order to avoid rising unemployment, to cushion the blow and make sure the economy can adjust as well as possible.”

But why should the Bank be willing to relax its target – a target set by the government? In practice, a temporary rise above 2% can still be consistent with the target if inflation is predicted to return to 2% within ‘a reasonable time period’.

But if even if the forecast rate of inflation were above 2% in two years’ time, there would still be some logic in the Bank not tightening monetary policy – by raising Bank Rate or ending, or even reversing, quantitative easing. This would be the case when there was, or forecast to be, stagflation, whether actual or as a result of monetary policy.

The aim of an inflation target of 2% is to help create a growth in aggregate demand consistent with the economy operating with a zero output gap: i.e. with no excess or deficient demand. But when inflation is caused by rising costs, such as that caused by a depreciation in the exchange rate, inflation could still rise even though the output gap were negative.

A rise in interest rates in these circumstances could cause the negative output gap to widen. The economy could slip into stagflation: rising prices and falling output. Hopefully, if the exchange rate stopped falling, inflation would fall back once the effects of the lower exchange rate had fed through. But that might take longer than 24 months or a ‘reasonable period of time’.

So even if not raising interest rates in a situation of stagflation where the inflation rate is forecast to be above 2% in 24 months’ time is not in the ‘letter’ of the policy, it is within the ‘spirit’.

But what of exchange rates? Mark Carney also said that “Our job is not to target the exchange rate, our job is to target inflation. But that doesn’t mean we’re indifferent to the level of sterling. It does matter, ultimately, for inflation and over the course of two to three years out. So it matters to the conduct of monetary policy.”

But not tightening monetary policy if inflation is forecast to go above 2% could cause the exchange rate to fall further. It seems as if trying to arrest the fall in sterling and prevent a fall into recession are conflicting aims when the policy instrument for both is the rate of interest.

The political business cycle – mark II

During the 1970s, commentators often referred to the ‘political business cycle’. As William Nordhaus stated in a 1989 paper. “The theory of the political business cycle, which analyzes the interaction of political and economic systems, arose from the obvious facts of life that voters care about the economy while politicians care about power.”

In the past, politicians would use fiscal, and sometimes monetary, policies to manipulate aggregate demand so that the economy was growing strongly at the time of the next election. This often meant doing unpopular things in the first couple of years of office to allow for popular things, such as tax cuts and increased government transfers, as the next election approached. This tended to align the business cycle with the election cycle. The economy would slow in the early years of a parliament and expand rapidly towards the end.

To some extent, this has been the approach since 2010 of first the Coalition and now the Conservative governments. Cuts to government expenditure were made ‘in order to clear up the mess left by the previous government’. At the time it was hoped that, by the next election, the economy would be growing strongly again.

But in adopting a fiscal mandate, the current government could be doing the reverse of previous governments. George Osborne has set the target of a budget surplus by the final year of this parliament (2019–20) and has staked his reputation on achieving it.

The problem, as we saw in the blog, Hitting – or missing – the government’s self-imposed fiscal targets is that growth in the economy has slowed and this makes it more difficult to achieve the target of a budget surplus by 2019–20. Given that achieving this target is seen to be more important for his reputation for ‘sound management’ of the public finances than that the economy should be rapidly growing, it is likely that the Chancellor will be dampening aggregate demand in the run-up to the next election. Indeed, in the latest Budget, he announced that specific measures would be taken in 2019–20 to meet the target, including a further £3.5 billion of savings from departmental spending in 2019–20. In the meantime, however, taxes would be cut (such as increasing personal allowances and cutting business rates) and government spending in certain areas would be increased. As the OBR states:

Despite a weaker outlook for the economy and tax revenues, the Chancellor has announced a net tax cut and new spending commitments. But he remains on course for a £10 billion surplus in 2019–20, by rescheduling capital investment, promising other cuts in public services spending and shifting a one-off boost to corporation tax receipts into that year.

But many commentators have doubted that this will be enough to bring a surplus. Indeed Paul Johnson, Director of the Institute for Fiscal Studies, stated on BBC Radio 4′s Today Programme said that “there’s only about a 50:50 shot that he’s going to get there. If things change again, if the OBR downgrades its forecasts again, I don’t think he will be able to get away with anything like this. I think he will be forced to put some proper tax increases in or possibly find yet further proper spending cuts”.

If that is the case, he will be further dampening the economy as the next election approaches. In other words, the government may be doing the reverse of what governments did in the past. Instead of boosting the economy to increase growth at election time, the government may feel forced to make further cuts in government expenditure and/or to raise taxes to meet the fiscal target of a budget surplus.

Riding the Japanese roller coaster

Sustained economic growth in Japan remains elusive. Preliminary Quarterly Estimates of GDP point to the Japanese economy having contracted by 0.4 per cent in the final quarter of 2015. This follows on from growth of 0.3 per cent in the third quarter, a contraction of 0.3 per cent in the second and growth of 1 per cent in the first quarter. Taken as a whole output in 2015 rose by 0.4 per cent compared to zero growth in 2014. The fragility of growth means that over the past 20 years the average annual rate of growth in Japan is a mere 0.8 per cent.

Chart 1 shows the quarter-to-quarter change in real GDP in Japan since the mid 1990s (Click here to download a PowerPoint of the chart). While economies are known to be inherently volatile the Japanese growth story over the past twenty or years so is one both of exceptional volatility and of repeated bouts of recession. Since the mid 1990s Japan has experienced 6 recessions, four since 2008.

Of the four recessions since 2008, the deepest was that from 2008 Q2 to 2009 Q1 which saw the economy shrink by 9.2 per cent. This was followed by a recession from 2010 Q4 to 2011 Q2 when the economy shrunk by 3.1 per cent, then from 2012 Q2 to 2012 Q4 when the economy shrunk by 0.9 per cent and from 2014 Q2 to 2014 Q3 when output fell another 2.7 per cent. As a result of these four recessionary periods the economy’s output in 2015 Q4 was actually 0.4 per cent less than in 2008 Q1.

Chart 2 shows the annual levels of nominal (actual) and real (constant-price) GDP in trillions of Yen (¥) since 1995. (Click here to download a PowerPoint of the chart). Over the period actual GDP has fallen from ¥502 trillion to ¥499 trillion (about £3 trillion at the current exchange rate) while GDP at constant 2005 prices has risen from ¥455 trillion to ¥528 trillion.

Chart 2 reveals an interesting phenomenon: the growth in real GDP at the same time as a fall in nominal GDP. So why has the actual value of GDP fallen slightly between 1995 and 2005? The answer is quite simple: deflation.

Chart 3 shows a protracted period of economy-wide deflation from 1999 to 2013. (Click here to download a PowerPoint of the chart). Over this period the GDP deflator fell each year by an average of 1.0 per cent. 2014 and 2015 saw a pick up in economy-wide inflation. However, the quarterly profile through 2015 shows the pace of inflation falling quite markedly. As we saw in Japan’s interesting monetary stance as deflation fears grow, policymakers are again concerned about the possibility of deflation and the risks that poses for growth.

As Chart 4 helps to demonstrate, a significant factor behind the latest slowdown in Japan’s growth is household spending. (Click here to download a PowerPoint of the chart). In 2015 household spending accounted for about 57 per cent by value of GDP in Japan. In the last quarter of 2015 real household spending fell by 0.9 per cent while across 2015 as a whole real household spending fell by 1.3 per cent. This follows on from a 0.8 per cent decrease in spending by households in 2014.

The recent marked weakening of household spending is a significant concern for the short term growth prospects of the Japanese economy. The roller coaster ride continues, unfortunately it appears that the ride is again downwards.

An oil glut

The demand for oil is growing and yet the price of oil, at around $46 per barrel over the past few weeks, remains at less than half that of the period from 2011 to mid 2014. The reason is that supply has been much larger than demand. The result has been a large production surplus and a growth in oil stocks. Supply did fall somewhat in October, which reduced the surplus in 2015 Q3 below than of the record level in Q2 – but the surplus was still the second highest on record.

What is more, the modest growth in demand is forecast to slow in 2016. Supply, however, is expected to decrease through the first three quarters of 2016, before rising again at the end of 2016. The result will be a modest rise in price into 2016, to around $56 per barrel, compared with an average of just over $54 per barrel so far for 2015 (click here for a PowerPoint of the chart below).

But why does supply remain so high, given such low prices? As we saw in the post The oil industry and low oil prices, it is partly the result of increases in supply from large-scale investment in new sources of oil over the past few years, such as the fracking of shale deposits, and partly the increased output by OPEC designed to keep prices low and make new investment in shale oil unprofitable.

So why then doesn’t supply drop off rapidly? As we saw in the post, A crude indicator of the economy (Part 2), even though shale oil producers in the USA need a price of around $70 or more to make investment in new sources profitable, the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel. This means that shale oil production will continue until the end of the life of the wells. Given that wells typically have a life of at least three years, it could take some time for the low prices to have a significant effect on supply. According to the US Energy Information Administration’s forecasts, US crude oil production will drop next year by only just over 5%, from an average of 9.3 million barrels per day in 2015 to 8.8 million barrels per day in 2016.

In the meantime, we can expect low oil prices to continue for some time. Whilst this is bad news for oil exporters, it is good news for oil importing countries, as the lower costs will help aid recovery.

What would Keynes say?

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.

What do the USA, UK and Africa have in common?

Economic growth is vital to an economy: it helps to create jobs and is crucial in stimulating confidence, both for businesses and consumers. Growth comes from various sources, both domestic and external, and so for each individual country it’s not just its growth rate that is important, but the growth rates of other countries, in particular those it trades with.

Recent data suggest that the global economy could be on the downturn and here we consider three countries/continents.

The US economy has been doing relatively well and we saw discussion by the Federal Reserve as to whether the economy was in a position to be able to handle an increase in interest rates. Although rates didn’t rise, there was a general consensus that a rate rise would not significantly harm the economy. However, perhaps those opinions may now be changing with the latest information regarding US growth. In the second quarter of 2015, growth was recorded at 3.9%, but according to the Department of Commerce, it fell to 1.5% for the third quarter. Though it’s still a solid growth rate, especially compared to other economies, it does represent a significant fall from quarter to quarter.

Many analysts suggest that this slowing is just a blip, partly the result of running down stocks, but it’s also a trend that has occurred in the UK. Although the fall in growth in the UK (see series IHYR) has been less than in the USA, it is still a fall. Annual growth was recorded at 2.7% in quarter 1, but fell to 2.4% in quarter 2 and to 2.3% in quarter 3 (with GDP in quarter 3 only 0.5% higher than in quarter 2). A big cause of this slowdown in growth has been a fall in manufacturing output and it is the service sector that prevented an even larger slowdown.

And it’s not just the West that is experiencing declining growth. The IMF has warned of a slowdown in economic growth in Africa. Although the absolute annual rate of growth at 3.75% is high compared to the UK, it does represent the slowest rate of growth in the past six years. One key factor has been the lower oil prices. Although this has helped to stimulate consumer spending in many countries, it has hit oil-producing countries.

With some of the big players experiencing slowdowns, world economic growth may be taking something of a dive. The Christmas period in many countries is when companies will make significant contributions to their annual sales, and this year these sales are going to be vital. The following articles consider the slowdowns in growth around the world.

What’s the outlook for the global economy?

The International Monetary Fund has just published its six-monthly World Economic Outlook (WEO). The publication assesses the state of the global economy and forecasts economic growth and other indicators over the next few years. So what is this latest edition predicting?

Well, once again the IMF had to adjust its global economic growth forecasts down from those made six months ago, which in turn were lower than those made a year ago. As Larry Elliott comments in the Guardian article linked below:

Every year, economists at the fund predict that recovery is about to move up a gear, and every year they are disappointed. The IMF has over-estimated global growth by one percentage point a year on average for the past four years.

In this latest edition, the IMF is predicting that growth in 2015 will be slightly higher in developed countries than in 2014 (2.0% compared with 1.8%), but will continue to slow for the fifth year in emerging market and developing countries (4.0% in 2015 compared with 4.6% in 2014 and 7.5% in 2010).

In an environment of declining commodity prices, reduced capital flows to emerging markets and pressure on their currencies, and increasing financial market volatility, downside risks to the outlook have risen, particularly for emerging market and developing economies.

So what is the cause of this sluggish growth in developed countries and lower growth in developing countries? Is lower long-term growth the new norm? Or is this a cyclical effect – albeit protracted – with the world economy set to resume its pre-financial-crisis growth rates eventually?

To achieve faster economic growth in the longer term, potential national output must grow more rapidly. This can be achieved by a combination of more rapid technological progress and higher investment in both physical and human capital. But in the short term, aggregate demand must expand sufficiently rapidly. Higher short-term growth will encourage higher investment, which in turn will encourage faster growth in potential national output.

But aggregate demand remains subdued. Many countries are battling to cut budget deficits, and lending to the private sector is being constrained by banks still seeking to repair their balance sheets. Slowing growth in China and other emerging economies is dampening demand for raw materials and this is impacting on primary exporting countries, which are faced with lower exports and lower commodity prices.

Quantitative easing and rock bottom interest rates have helped somewhat to offset these adverse effects on aggregate demand, but as the USA and UK come closer to raising interest rates, so this could dampen global demand further and cause capital to flow from developing countries to the USA in search of higher interest rates. This will put downward pressure on developing countries’ exchange rates, which, while making their exports more competitive, will make it harder for them to finance dollar-denominated debt.

As we have seen, long-term growth depends on growth in potential output, but productivity growth has been slower since the financial crisis. As the Foreword to the report states:

The ongoing experience of slow productivity growth suggests that long-run potential output growth may have fallen broadly across economies. Persistently low investment helps explain limited labour productivity and wage gains, although the joint productivity of all factors of production, not just labour, has also been slow. Low aggregate demand is one factor that discourages investment, as the last World Economic Outlook report showed. Slow expected potential growth itself dampens aggregate demand, further limiting investment, in a vicious circle.

But is this lower growth in potential output entirely the result of lower demand? And will the effect be permanent? Is it a form of hysteresis, with the effect persisting even when the initial causes have disappeared? Or will advances in technology, especially in the fields of robotics, nanotechnology and bioengineering, allow potential growth to resume once confidence returns?

Which brings us back to the short and medium terms. What can be done by governments to stimulate sustained recovery? The IMF proposes a focus on productive infrastructure investment, which will increase both aggregate demand and aggregate supply, and also structural reforms. At the same time, loose monetary policy should continue for some time – certainly as long as the current era of falling commodity prices, low inflation and sluggish growth in demand persists.

  1. Look at the forecasts made in the WEO October editions of 2007, 2010 and 2012 for economic growth two years ahead and compare them with the actual growth experienced. How do you explain the differences?
  2. Why is forecasting even two years ahead fraught with difficulties?
  3. What factors would cause a rise in (a) potential output; (b) potential growth?
  4. What is the relationship between actual and potential economic growth?
  5. Explain what is meant by hysteresis. Why may recessions have a permanent negative effect, not only on trend productivity levels, but on trend productivity growth?
  6. What are the current downside risks to the global economy?
  7. Why have commodity prices fallen? Who gains and who loses from lower commodity prices? Does it matter if falling commodity prices in commodity importing countries result in negative inflation?
  8. To what extent can exchange rate depreciation help commodity exporting countries?
  9. What is meant by the output gap? How have IMF estimates of the size of the output gap changed and what is the implication of this for actual and potential economic growth?
