As the Chancellor of the Exchequer, Philip Hammond, delivers his first Autumn statement, both the Office for Budget Responsibility (OBR) and the National Institute for Economic and Social Research (NIESR) have published updated forecasts for government borrowing and government debt.
They show a rise in government borrowing compared with previous forecasts. The main reason for this is a likely slowdown in the rate of economic growth and hence in tax revenues, especially in 2017. Last March, the OBR forecast GDP growth of 2.2% for 2017; it has now revised this down to 1.4%.
This forecast slowdown is because of a likely decline in the growth of aggregate demand caused by a decline in investment as businesses become more cautious given the uncertainty about the UK’s relationships with the rest of the world post Brexit. There is also likely to be a slowdown in real consumer expenditure as inflation rises following the fall in the pound of around 15%.
But what might be more surprising is that the public finances are not forecast to deteriorate even further. The OBR forecasts that the deficit will increase by a total of £122bn to £216bn over the period from 2016/17 to 2020/21. The NIESR predicts that it will rise by only £50bn to £187bn – but this is before the additional infrastructure spending and other measures announced in the Autumn Statement.
One reason is looser monetary policy. Following the Brexit vote, the Bank of England cut Bank Rate from 0.5% to 0.25% and introduced further quantitative easing. This makes it cheaper to finance government borrowing. What is more, the additional holdings of bonds by the Bank mean that the Bank returns to the government much of the interest (coupon payments) that would otherwise have been paid to the private sector.
Then, depending on the nature of the UK’s post-Brexit relationships with the EU, there could be savings in contributions to the EU budget – but just how much, no-one knows at this stage.
Finally, it depends on just what effects the measures announced in the Autumn Statement will have on tax revenues and government spending. We will examine this in a separate blog.
But even though public-sector borrowing is likely to fall more slowly than before the Brexit vote, the trajectory is still downward. Indeed, the previous Chancellor, George Osborne, had set a target of achieving a public-sector surplus by 2019/20.
But, would eventually bringing the public finances into surplus be desirable? Apart from the dampening effect on aggregate demand, such a policy could lead to underinvestment in infrastructure and other public-sector capital. There is thus a strong argument for continuing to run a deficit on the public-sector capital account to fund public-sector investment – such investment will increase incomes and social wellbeing in the future. It makes sense for the government to borrow for investment, just as it makes sense for the private sector to do so.

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.

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).

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.

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.
