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)
Questions
- 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’?
The linked article below from The Economist looks at whether the election of Donald Trump, the effects of the Brexit vote and policies being pursued elsewhere in the world mark a new macroeconomic era. We may be about to witness rising inflation and the end of the era of tight fiscal policy and loose monetary policy. We might see a return of a more Keynesian approach to macreconomic policy.
According to the article, since the financial crisis of 2008, we have been witnessing economies stuck in a liquidity trap. In such cases, there is little scope for further reductions in interest rates. And increases in money supply, in the form of quantitative easing, tend to be held in idle balances, rather than being spent on goods and services. The idle balances take the form of increased bank reserves to rebuild their capital base and increased purchases of assets such as shares and property.
Even if people did believe that monetary policy would work to boost aggregate demand and result in higher inflation, then they would also believe that any such boost would be temporary as central banks would then have to tighten monetary policy to keep inflation within the target they had been set. This would limit spending increases, keeping the economy in the liquidity trap.
With a liquidity trap, fiscal policy is likely to be much more effective than monetary policy in boosting aggregate demand. However, its scope to pull an economy out of recession and create sustained higher growth depends on the extent to which governments, and markets, can tolerate higher budget deficits and growing debt. With governments seeking to claw down deficits and ultimately debt, this severely limits the potential for using fiscal policy.
With the election of Donald Trump, we might be entering a new era of fiscal policy. He has promised large-scale infrastructure spending and tax cuts. Although he has also promised to reduce the deficit, he is implying that this will only occur when the economy is growing more rapidly and hence tax revenues are increasing.
Is Donald Trump a Keynesian? Or are such promises merely part of campaigning – promises that will be watered down when he takes office in January? We shall have to wait and see whether we are about to enter a new era of macroeconomic policy – an era that has been increasingly advocated by international bodies, such as the IMF and the OECD (see the blog post, OECD goes public).

Slumponomics: Trump and the political economy of liquidity traps The Economist (10/11/16)
Questions
- Explain what is meant by ‘the liquidity trap’.
- Why is monetary policy relatively ineffective in a liquidity trap? Use a diagram to support your argument.
- Why is fiscal policy (in the absence of public-sector deficit targets) relatively effective in a liquidity trap? Again, use a diagram to support your argument.
- Examine how the Japanese government attempted to escape the liquidity trap? (Search this site for ‘Abenomics’.)
- In what ways may the depreciation of the pound since the Brexit vote help the UK to escape the liquidity trap?
- Could a different form of quantitative easing, known as ‘helicopter money’, whereby government or private spending is financed directly by new money, allow countries to escape the liquidity trap? (Search this site for ‘helicopter money’.)
- Why may a political upheaval be necessary for a country to escape the liquidity trap?
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.

Questions
- Explain the difference between cost-push and demand-pull inflation.
- If inflation rises as a result of rising costs, what can we say about the rate of increase in these costs? Is it likely that cost-push inflation would persist beyond the effects of a supply-side shock working through the economy?
- Can interest rates be used to control both inflation and the exchange rate? Explain why or why not.
- What is the possible role of fiscal policy in the current situation of a falling exchange rate and rising inflation?
- Why does the Bank of England target the rate of inflation in 24 months’ time and not the rate today? (After all, the Governor has to write a letter to the Chancellor explaining why inflation in any month is more than 1 percentage point above or below the target of 2%.)
- What is meant by a zero output gap? Is this the same as a situation of (a) full employment, (b) operating at full capacity? Explain.
- Why have UK gilt yields soared in the light of a possible ‘hard Brexit’, a falling exchange rate and rising inflation?
The Bank of England has responded to forecasts of a dramatic slowdown in the UK economy in the wake of the Brexit vote. On 4th August, it announced a substantial easing of monetary policy, but still left room for further easing later.
Its new measures are based on the forecasts in its latest 3-monthly Inflation Report. Compared with the May forecasts, the Report predicts that, even with the new measures, aggregate demand growth will slow dramatically. As a result, over the next two years cumulative GDP growth will be 2.5% lower than it would have been with a Remain vote and unemployment will rise from 4.9% to around 5.5%.
What is more, the slower growth in aggregate demand will impact on aggregate supply. As the Governor said in his 
opening remarks at the Inflation Report press conference:
“The weakness in demand will itself weigh on supply as a period of low investment restrains growth in the capital stock and productivity.
There could also be more direct implications for supply from the decision to leave the European Union. The UK’s trading relationships are likely to change, but precisely how will be unclear for some time. If companies are uncertain about the future impact of this on their businesses, they could delay decisions about building supply capacity or entering new markets.”
Three main measures were announced.
|
|
| • |
A cut in Bank Rate from 0.5% to 0.25%. This is the first time Bank Rate has been changed since March 2009. The Bank hopes that banks will pass this on to customers in terms of lower borrowing rates. |
| • |
A new ‘Term Funding Scheme (TFS)’. “Compared to the old Funding for Lending Scheme, the TFS is a pure monetary policy instrument that is likely to be more stimulative pound-for-pound.” The scheme makes £100bn of central bank reserves available as loans to banks and building societies. These will be at ultra-low interest rates to enable banks to pass on the new lower Bank Rate to customers in all forms of lending. What is more, banks will be charged a penalty if they do not lend this money. |
| • |
An expansion of the quantitative easing programme beyond the previous £375 billion of gilt (government bond) purchases. This will consist of an extra £60bn of gilt purchases and the purchase of up to £10bn of UK corporate bonds. |
The Bank recognises that there is a limit to what monetary policy can do and that there is also a role to play for fiscal policy. The new Chancellor, Philip Hammond, is considering what fiscal measures can be taken, including spending on infrastructure projects. These are likely to have relative high multiplier effects and would also increase aggregate supply at the same time. But we will have to wait for the Autumn Statement to see what measures will be taken.
But despite the limits to monetary policy, there is more the Bank of England could do. It already recognises that there may have to be a further cut in Bank Rate, perhaps to 0.1% or even to 0% (the ECB has a 0% rate). There could also be additional quantitative easing or additional term funding to banks.
Some economists argue that the Bank should go further still and, in conjunction with the Treasury, provide new money directly to fund infrastructure spending or tax cuts, or even as cash handouts to households. This extra money provided to the government would not increase government borrowing.
We discussed the use of this version of ‘helicopter money’ in the blogs, A flawed model of monetary policy, Global warning and People’s quantitative easing. Some of the articles below also consider the potential for this type of monetary policy. In a letter to The Guardian 35 economists advocate:
A fiscal stimulus financed by central bank money creation [which] could be used to fund essential investment in infrastructure projects – boosting the incomes of businesses and households, and increasing the public sector’s productive assets in the process. Alternatively, the money could be used to fund either a tax cut or direct cash transfers to households, resulting in an immediate increase of household disposable incomes.

Questions
- Find out the details of the previous Funding for Lending (FLS) scheme. How does the new Term Funding Scheme (TFS) differ from it? Why does the Bank of England feel that TFS is likely to be more effective than FLS in expanding lending?
- What is the transmission mechanism between asset purchases and real aggregate demand?
- What factors determine the level of borrowing in the economy? How is cutting Bank Rate from 0.5% to 0.25% likely to affect borrowing?
- If the Bank of England’s latest forecast is for a significant reduction in economic growth from its previous forecast, why did the Bank not introduce stronger measures, such as larger asset purchases or a cut in Bank Rate to 0.1%?
- What are the advantages and disadvantages of helicopter money in the current circumstances? If helicopter money were used, would it be better to use it for funding public-sector infrastructure projects or for cash handouts to households, either directly or in the form of tax cuts?

The UK has voted to leave the EU by 17 410 742 votes (51.9% or 37.4% of the electorate) to 16 141 241 votes (48.1% or 34.7% of the electorate). But what will be the economic consequences of the vote?
To leave the EU, Article 50 must be invoked, which starts the process of negotiating the new relationship with the EU. This, according to David Cameron, will happen when a new Conservative Prime Minister is chosen. Once Article 50 has been invoked, negotiations must be completed within two years and then the remaining 27 countries will decide on the new terms on which the UK can trade with the EU. As explained in the blog, The UK’s EU referendum: the economic arguments, there are various forms the new arrangements could take. These include:
‘The Norwegian model’, where Britain leaves the EU, but joins the European Economic Area, giving access to the single market, but removing regulation in some key areas, such as fisheries and home affairs. Another possibility is ‘the Swiss model’, where the UK would negotiate trade deals on an individual basis. Another would be ‘the Turkish model’ where the UK forms a customs union with the EU. At the extreme, the UK could make a complete break from the EU and simply use its membership of the WTO to make trade agreements.
The long-term economic effects would thus depend on which model is adopted. In the Norwegian model, the UK would remain in the single market, which would involve free trade with the EU, the free movement of labour between the UK and member states and contributions to the EU budget. 
The UK would no longer have a vote in the EU on its future direction. Such an outcome is unlikely, however, given that a central argument of the Leave camp has been for the UK to be able to control migration and not to have to pay contributions to the EU budget.
It is quite likely, then, that the UK would trade with the EU on the basis of individual trade deals. This could involve tariffs on exports to the EU and would involve being subject to EU regulations. Such negotiations could be protracted and potentially extend beyond the two-year deadline under Article 50. But for this to happen, there would have to be agreement by the remaining 27 EU countries. At the end of the two-year process, when the UK exits the EU, any unresolved negotiations would default to the terms for other countries outside the EU. EU treaties would cease to apply to the UK.
It is quite likely, then, that the UK would face trade restrictions on its exports to the EU, which would adversely affect firms for whom the EU is a significant market. 
Where practical, some firms may thus choose to relocate from the UK to the EU or move business and staff from UK offices to offices within the EU. This is particularly relevant to the financial services sector. As the second Economist article explains:
In the longer run … Britain’s financial industry could face severe difficulties. It thrives on the EU’s ‘passport’ rules, under which banks, asset managers and other financial firms in one member state may serve customers in the other 27 without setting up local operations. …
Unless passports are renewed or replaced, they will lapse when Britain leaves. A deal is imaginable: the EU may deem Britain’s regulations as ‘equivalent’ to its own. But agreement may not come easily. French and German politicians, keen to bolster their own financial centres and facing elections next year, may drive a hard bargain. No other non-member has full passport rights.
But if long-term economic effects are hard to predict, short-term effects are happening already.
The pound fell sharply as soon as the results of the referendum became clear. By the end of the day it had depreciated by 7.7% against the dollar and 5.7% against the euro. A lower pound will make imports more expensive and hence will drive up prices and reduce the real value of sterling. On the other had, it will make exports cheaper and act as a boost to exports.
If inflation rises, then the Bank of England may raise interest rates. This could have a dampening effect on the economy, which in turn would reduce tax revenues. The government, if it sticks to its fiscal target of achieving a public-sector net surplus by 2020 (the Fiscal Mandate), may then feel the need to cut government expenditure and/or raise taxes. Indeed, the Chancellor argued before the vote that such an austerity budget may be necessary following a vote to leave.
Higher interest rates could also dampen house prices as mortgages became more expensive or harder to obtain. The exception could be the top end of the market where a large proportion are buyers from outside the UK whose demand would be boosted by the depreciation of sterling.
But given that the Bank of England’s remit is to target inflation in 24 month’s time, it is possible that any spike in inflation is temporary and this may give the Bank of England leeway to cut Bank Rate from 0.5% to 0.25% or even 0% and/or to engage in further quantitative easing.
One major worry is that uncertainty may discourage investment by domestic companies. It could also discourage inward investment, and international companies many divert investment to the EU. Already some multinationals have indicated that they will do just this. Shares in banks plummeted when the results of the vote were announced.
Uncertainty is also likely to discourage consumption of durables and other big-ticket items. The fall in aggregate demand could result in recession, again necessitating an austerity budget if the Fiscal Mandate is to be adhered to.
We live in ‘interesting’ times. Uncertainty is rarely good for an economy. But that uncertainty could persist for some time.

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.
