The following blog is inspired by my teaching of macroeconomic issues to my final year students at Aston University. In the classes we’ve been discussing important aspects of monetary and fiscal policy design. What has become clear to me and my students is that the trade-offs which characterise the discipline of economics are certainly alive and well in the current environment in which monetary and fiscal policy choices are being made.
To demonstrate this we consider here some of the discussions we’ve had in class around central bank independence and monetary policy mandates. We’ve also looked at fiscal policy. Here we’ve examined the state of the public finances and the importance that seems to be attached to debt stabilisation and the imposition of debt rules.
Delegation and central bank mandates
My teaching this term began by introducing my students to one of the most important and influential monetary policy models. This is the model of Kydland and Prescott. Their model, published in the Journal of Political Economy in 1977 has become the theoretical bedrock for the modern-day operational independence of central banks.1
The model explores how systemically high inflation can become established in economies when policymakers have the political incentive to lower unemployment or increase output above its long-run equilibrium value. This may be the case if governments operate monetary policy rather than the central bank (of if the central bank operates monetary policy but follows government objectives). By adopting expansionary monetary policy, governments can increase their popularity.
But this is likely to be short-lived, as any increased economic activity will only be temporary (assuming that the natural-rate hypothesis holds). Soon, inflation will rise.
But, if an election is on the horizon, there may be enough time to boost output and employment before inflation rises. In other words, an expectations-augmented Phillips curve may present governments with an incentive to loosen monetary policy and worry about the inflation consequences after the election.
However, the resulting ‘inflation surprise’ through the loosening of monetary policy means a fall in real pay and therefore in purchasing power. If people suspect that governments will be tempted to loosen policy, they will keep their expectations of inflation higher than the socially optimal inflation rate. Consequently, low-inflation targets lack credibility when governments have the temptation to loosen monetary policy. Such targets are time-inconsistent because governments have an incentive to renege and deliver higher inflation through a looser monetary policy. The result is an inflation bias.
Central bank independence
To prevent this inflationary bias arising, many central banks around the world have been given some form of operational independence with a mandate centred around an inflation-rate target. By delegating monetary policy to a more conservative central bank, the problem of inflationary bias can be addressed.
Yet central bank independence is not without its own issues and this has been an important part of the discussions with my students. Today, many economies are continuing to experience the effects of the inflationary shocks that began in 2021 (see Chart 1 for the UK CPI inflation rate: click here for a PowerPoint). The question is whether the appointment of a conservative or hard-nosed hawkish central banker trades off the stabilisation of inflation for greater volatility in output or unemployment.
The inflation–output stabilisation trade-off is closely associated with the works of Kenneth Rogoff2 and John Taylor3. The latter is known for his monetary policy rule, which has become known as the ‘Taylor rule’. This advocates that a rules-based central bank ought to place weight on both inflation and output stabilisation.
This is not without its own issues, however, since, by also placing weight on output stabilisation, we are again introducing the possibility of greater inflationary bias in policy making. Hence, while the act of delegation and a rules- or target-based approach may mitigate the extent of the bias relative to that in the Kydland and Prescott model, there nonetheless still remain issues around the design of the optimal framework for the conduct of monetary policy.
Indeed, the announcement that the UK had moved into recession in the last two quarters of 2023 can be seen as evidence that an otherwise abstract theoretical trade-off between inflation and output stabilisation is actually very real.
My classroom discussions have also shown how economic theory struggles to identify an optimal inflation-rate target. Beyond accepting that a low and stable inflation rate is desirable, it is difficult to address fully the student who asks what is so special about a 2% inflation target. Would not a 3% target, for example, be preferable, they might ask?
Whilst this may sound somewhat trivial, it has real-world consequences. In a world that now seems to be characterised by greater supply-side volatility and by more frequent inflation shocks than we were used to in recent history, might a higher inflation rate target be preferable? Certainly, one could argue that, with an inflation–output stabilisation trade-off, there is the possibility that monetary policy could be unduly restrictive in our potential new macroeconomic reality. Hence, we might come to see governments and central banks in the near future revisiting the mandates that frame the operation of their monetary policy. Time will tell.
Fiscal policy and debt stabilisation
The second topic area that I have been discussing in my final-year macroeconomics classes has centred around fiscal policy and the state of the public finances. The context for this is that we have seen a significant increase in public debt-to-GDP ratios over the past couple of decades as the public sector has attempted to absorb significant economic shocks. These include the global financial crisis of 2007–8, the COVID-19 pandemic and the cost-of-living crisis. These interventions in the case of the UK have seen its public debt-to-GDP ratio more than triple since the early 2000s to close to 100% (see Chart 2: click here for a PowerPoint).
Understandably, given the stresses placed on the public finances, economists have increasingly debated issues around debt sustainability. These debates have been mirrored by politicians and policymakers. A key question is whether to have a public debt rule. The UK has in recent years adopted such a rule. The arguments for a rule centre on ensuring sound public finances and maintaining the confidence of investors to purchases public debt. A debt rule therefore places a discipline on fiscal policy, with implications for taxation and spending.
How easy it is to stick to a debt rule depends on three key factors. It will be harder to stick to the rule:
- The higher the current debt-to-GDP ratio and hence the more it needs to be reduced to meet the rule.
- The higher the rate of interest and hence the greater the cost of servicing the public debt.
- The lower the rate of economic growth and hence the less quickly will tax revenues rise.
With a given debt-to-GDP ratio, a given average interest rate payable on its debt, and a given rate of economic growth, we can determine the primary fiscal balance relative to GDP a government would need to meet for the debt-to-GDP ratio to remain stable. This is known as the ‘debt-stabilising primary balance’. The primary balance is the difference between a government’s receipts and its expenditures less the interest payments on its debt.
This fiscal arithmetic is important in determining a government’s fiscal choices. It shows the implications for spending and taxation. These implications become ever more important and impactful on people, businesses, and society when the fiscal arithmetic becomes less favourable. This is a situation that appears to be increasingly the case for many countries, including the UK, as the rate of interest on public debt rises relative to a country’s rate of economic growth. As this happens, governments are increasingly required to run healthier primary balances. This of course implies a tightening of their fiscal stance.
Hence, the fiscal conversations with my students have focused on both the benefits and the costs of debt-stabilisation. In respect of the costs, a few issues have arisen.
First, as with the inflation-rate target, it is hard to identify an optimal public debt-to-GDP ratio number. While the fiscal arithmetic may offer some clue, it is not straightforward to address the question as to whether a debt-to-GDP ratio of say 100% or 120% would be excessive for the UK.
Second, it is possible that the debt stabilisation itself can make the fiscal arithmetic of debt stabilisation more difficult. This occurs if fiscal consolidation itself hinders long-term economic growth, which then makes the fiscal arithmetic more difficult. This again points to the difficulties in designing policy frameworks, whether they be for monetary or fiscal policy.
Third, a focus on debt stabilisation alone ignores the fact that there are two sides to any sector’s balance sheet. It would be very unusual when assessing the well-being of businesses or households if we were to ignore the asset side of their balance sheet. Yet, this is precisely the danger of focusing on public debt at the exclusion of what fiscal choices can mean for public-sector assets, from which we all can potentially benefit. Hence, some would suggest a more balanced approach to assessing the soundness of the public finances might involve a net worth (assets less liabilities) measure. This has parallels with the debates around whether mandates of central banks should be broader.
Applications in macroeconomics
What my teaching of a topics-based macroeconomics module this term has vividly demonstrated is that concepts, theories, and models come alive, and are capable of being understood better, when they are used to shine a light on real-world issues. The light being shone on monetary and fiscal policy in today’s turbulent macroeconomic environment is perhaps understandably very bright.
Indeed, the light being shone on fiscal policy in the UK and some other countries facing an upcoming election, is intensified further with the state of the public finances shaping much of the public discourse on fiscal choices. Hopefully, my students will continue to debate these important issues beyond their graduation, stressing their importance for people’s lives and, in doing so, going beyond the abstract.

In an attempt to prevent recession following the financial crisis of 2007–8, many countries adopted both expansionary monetary policy and expansionary fiscal policy – and with some success. It is likely that the recession would have been much deeper without such policies
But with growing public-sector deficits caused by the higher government expenditure and sluggish growth in tax receipts, many governments soon abandoned expansionary fiscal policy and relied on a mix of loose monetary policy (with ultra low interest rates and quantitative easing) but tight fiscal policy in an attempt to claw down the deficits.
But such ‘austerity’ policies made it much harder for loose monetary policy to boost aggregate demand. The problem was made worse by the attempt of both banks and individuals to ‘repair’ their balance sheets. In other words banks became more cautious about lending, seeking to build up reserves; and many individuals sought to reduce their debts by cutting down on spending. Both consumer spending and investment were slow to grow.
And yet government and central banks, despite the arguments of Keynesians, were reluctant to abandon their reliance solely on monetary policy as a means of boosting aggregate demand. But gradually, influential international institutions, such as the IMF (see also) and World Bank, have been arguing for an easing of austerity fiscal policies.
The latest international institution to take a distinctly more Keynesian stance has been the Organisation for Economic Co-operation and Development (OECD). In its November 2015 Economic Outlook it had advocated some use of public-sector investment (see What to do about slowing global growth?. But in its Interim Economic Outlook of February 2016, it goes much further. It argues that urgent action is needed to boost economic growth and that this should include co-ordinated fiscal policy. In introducing the report, Catherine L Mann, the OECD’s Chief Economist stated that:
“Across the board there are lower interest rates, except for the United States. It allows the authorities to undertake a fiscal action at very very low cost. So we did an exercise of what this fiscal action might look like and how it can contribute to global growth, but also maintain fiscal sustainability, because this is an essential ingredient in the longer term as well.
So we did an experiment of a two-year increase in public investment of half a percentage point of GDP per annum undertaken by all OECD countries. This is an important feature: it’s everybody doing it together – it’s a collective action, because it’s global growth that is at risk here – our downgrades [in growth forecasts] were across the board – they were not just centred on a couple of countries.
So what is the effect on GDP of a collective fiscal action of a half a percentage point of GDP [increase] in public investment in [high] quality projects. In the United States, the euro area, Canada and the UK, who are all contributors to this exercise, the increase in GDP is greater than the half percentage point [increase] in public expenditure that was undertaken. Even if other countries don’t undertake any fiscal expansion, they still get substantial increases in their growth rates…
Debt to GDP in fact falls. This is because the GDP effect of quality fiscal stimulus is significant enough to raise GDP (the denominator in the debt to GDP ratio), so that the overall fiscal sustainability [debt to GDP] improves.”
What is being argued is that co-ordinated fiscal policy targeted on high quality infrastructure spending will have a multiplier effect on GDP. What is more, the faster growth in GDP should outstrip the growth in government expenditure, thereby allowing debt/GDP ratios to fall, not rise.
This is a traditional Keynesian approach to tackling sluggish growth, but accompanied by a call for structural reforms to reduce inefficiency and waste and improve the supply-side of the economy.

It is one year since the election of Shinzo Abe in Japan. He immediately embarked on a radical economic policy to stimulate the Japanese economy, which had suffered from years of stagnation. There have been three parts (or three arrows) to his policy: fiscal policy and monetary policy to stimulate aggregate demand and supply-side policy to increase productivity.
As the previous post explains:
“The first arrow is monetary policy. The Bank of Japan has engaged in extensive quantitative easing through bond purchases in order to drive down the exchange rate (see A J-curve for Japan?), stimulate expenditure and increase the rate of inflation. A target inflation rate of 2% has been set by the Bank of Japan. Part of the problem for the Japanese economy over the years has been stagnant or falling prices. Japanese consumers have got used to waiting to spend in the hope of being able to buy at lower prices. Similarly, Japanese businesses have often delayed stock purchase. By committing to bond purchases of whatever amount is necessary to achieve the 2% inflation target, the central bank hopes to break this cycle and encourage people to buy now rather than later.
The second arrow is fiscal policy. Despite having the highest debt to GDP ratio in the developed world, Japan is embarking on a large-scale programme of infrastructure investment and other public works. The package is worth over $100bn. The expansionary fiscal policy is accompanied by a longer-term plan for fiscal consolidation as economic growth picks up. In the short term, Japan should have no difficulty in financing the higher deficit, given that most of the borrowing is internal and denominated in yen.
The third arrow is supply-side policy. On 5 June, Shinzo Abe unveiled a series of goals his government would like to achieve in order to boost capacity and productivity. These include increasing private-sector investment (both domestic and inward), infrastructure expenditure (both private and public), increasing farmland, encouraging more women to work by improving day-care facilities for children, and deregulation of both goods, capital and labour markets. The prime minister, however, did not give details of the measures that would be introduced to achieve these objectives. More details will be announced in mid-June.”

Questions
- Demonstrate on (a) an aggregate demand and supply diagram and (b) a Keynesian 45° line diagram the effects of the three arrows (assuming they are successful) in meeting their objectives.
- Why has Japan found it so hard to achieve economic growth over the past 20 years?
- How has the Japanese economy performed over the past 12 months?
- What lessons can be learnt by the UK and eurozone countries from Japan’s three arrows?
- Why is the second arrow problematic, given the size of Japan’s general government debt? Does the proportion of Japanese debt owed overseas affect the argument?
- In what ways do the three arrows (a) support each other; (b) conflict with each other?
- Why is the structure of the labour market in Japan acting as a break on economic growth? What policies are being, or could be, pursued to tackle these structural problems?
Since coming to office in December 2012, Shinzo Abe’s government has been determined to revive the Japanese economy. For the past 20 years, Japan’s growth has averaged only 0.8% per annum. This compares with 1.3% for Germany, 2.3% for the UK, 2.6% for the USA, 4.9% for South Korea and 10.4% for China.
Japanese real GDP per capita was only 14.5% higher in 2012 than 20 years earlier. This compares with figures for Germany, the UK, the USA, South Korea and China of 27%, 45%, 34%, 126% and 497% respectively.
So what has the Japanese government done to boost both short-term and long-term growth after years of stagnation? There are ‘three arrows’ to the policy, targeted at reviving and sustaining economic growth.
The first arrow is monetary policy. The Bank of Japan has engaged in extensive quantitative easing through bond purchases in order to drive down the exchange rate (see A J-curve for Japan?), stimulate expenditure and increase the rate of inflation. A target inflation rate of 2% has been set by the Bank of Japan. Part of the problem for the Japanese economy over the years has been stagnant or falling prices. Japanese consumers have got used to waiting to spend in the hope of being able to buy at lower prices. Similarly, Japanese businesses have often delayed stock purchase. By committing to bond purchases of whatever amount is necessary to achieve the 2% inflation target, the central bank hopes to break this cycle and encourage people to buy now rather than later.
The second arrow is fiscal policy. Despite having the highest debt to GDP ratio in the developed world, Japan is embarking on a large-scale programme of infrastructure investment and other public works. The package is worth over $100bn. The expansionary fiscal policy is accompanied by a longer-term plan for fiscal consolidation as economic growth picks up. In the short term, Japan should have no difficulty in financing the higher deficit, given that most of the borrowing is internal and denominated in yen.
The third arrow is supply-side policy. On 5 June, Shinzo Abe unveiled a series of goals his government would like to achieve in order to boost capacity and productivity. These include increasing private-sector investment (both domestic and inward), infrastructure expenditure (both private and public), increasing farmland, encouraging more women to work by improving day-care facilities for children, and deregulation of both goods, capital and labour markets. The prime minister, however, did not give details of the measures that would be introduced to achieve these objectives. More details will be announced in mid-June.
The following videos and articles look at the three arrows of Abenomics and the effects they are having on confidence and attitudes as well as on expenditure, output and the exchange rate. They also look at the crucial third arrow: at whether supply-side reforms will be enough to achieve a sustained increase in economic growth.

At the start of 2013, the USA faces a ‘fiscal cliff’. By this is meant that, without agreement by Congress on new fiscal measures, the USA will be forced into tax rises and expenditure cuts of around $650 billion (over 4% of GDP). This would probably push the economy straight back into recession. This in turn would have a serious dampening effect on the global economy.
But why would fiscal policy be automatically tightened? The first reason is that tax cuts given under the George W. Bush administration during 2001–3 (largely to the rich) are due to expire. Also a temporary cut in payroll taxes and an increase in tax credits given by President Obama are also due to end. These tax increases would form the bulk of the tightening. The average US household would pay an extra $3500 in taxes, reducing after-tax income by around 6%.
The second reason is that various government expenditure programmes are scheduled to be reduced. These reductions in expenditure amount to around $110 billion.
It is likely, however, that Congress will agree to delay or limit the tax increases or expenditure cuts; politicians on both sides want to avoid sending the economy back into recession. But what the agreement will be is not at all clear at this stage.
Republicans are taking a tougher line than Democrats on cutting the budget deficit; they are calling for considerably less restraint in implementing the government expenditure cuts. On the other hand, they are likely to be less willing to raise taxes.
But unless something is done, the consequences for 2013 could be dire. The fiscal cliff edge rapidly approaches.
