Tag: trade-offs

The mandates of central banks around the world are typically focused on controlling inflation. In many cases, this is accompanied by operational independence from government, but with the government setting an inflation target. The central bank then chooses the appropriate monetary policy to achieve the inflation target. This is argued to provide the conditions that can deliver lower and less variable inflation rates – at least over the longer term.

However, some economists argue that this has the potential to create the conditions for greater economic volatility and financial instability. The events surrounding the collapse of Silicon Valley Bank (SVB) – the largest since the global financial crisis – have helped to reignite these debates.

Inflation targeting central banks

The theoretical foundations for delegating monetary policy to central banks with mandates to meet an inflation rate target is often attributed to the paper of Fynn Kydland and Edward Prescott published in the Journal of Political Economy in 1977. It argues that if governments, rather than independent central banks, operate monetary policy, systemically-high inflation can become established if low-inflation announcements by governments lack credibility. Delegation of monetary to a central bank with an inflation rate target, however, can create the necessary conditions for credibility. This, in turn, gives the public confidence to maintain lower and more stable inflationary expectations than would otherwise be the case.

To mitigate the problem of a potential inflationary bias, it is argued that governments should delegate monetary policy to a conservative central banker: one that places less weight on output or employment stabilisation and more weight on inflation stabilisation than does society. However, as identified by Kenneth Rogoff in his paper published in the Quarterly Journal of Economics in 1985, this raises the spectre of greater volatility in output and employment when economies are buffeted by supply shocks.

Inflation–output stabilisation trade-off

The inflation–output stabilisation trade-off identified by Rogoff has particular relevance to the macroeconomic environment experienced by many countries in recent times. As economies began to open up after the pandemic, demand–supply imbalances saw the emergence of inflationary pressures. These pressures were then exacerbated by the Russian invasion of Ukraine, which drove up commodity prices.

Rather than pursuing a less contractionary policy in the face of these supply shocks so as to avoid recession, central banks stuck to their inflation mandates and hence raised interest rates significantly so as to bring inflation back to target as soon as possible. But this hampered economic recovery.

Inflation–financial stability trade-off

Yet the recent financial turmoil suggests a further inflation–stability trade-off: an inflation–financial stability trade-off. By raising interest rates, different sectors of the economy are liable to greater financial distress. This distress has contributed to the collapse of Silicon Valley Bank and Signature Bank, and led to a significant injection of funds by large US banks into First Republic. The fear is of a contagion within the financial sector, which then spills into other sectors of the economy.

The debate about central bank mandates and the weight attached to inflation stability relative to other objectives is therefore centre stage of macroeconomic policy debates.

  1. Explain the argument that the delegation of monetary policy can help to keep the average rate of inflation lower.
  2. How might the monetary policy responses of central banks to an inflation shock create the possibility of an inflation–output stabilisation trade-off?
  3. What do you understand by a Taylor rule? Could this help to alleviate the inflation-output stabilisation trade-off?
  4. Some economists argue that there is less of a trade-off between inflation and output stability with demand-pull inflation because of a so-called ‘divine coincidence’ in monetary policy. Why might this be the case?
  5. What do you understand by the term ‘financial distress’? What metrics could be used to capture this for different sectors of the economy?
  6. Explain how financial contagion can spread both within and between different sectors of the economy.

Throughout the pandemic, the fight against COVID-19 has often been framed in terms of striking a balance between the health of the public and the health of the economy. This leads to the assumption that a trade-off must exist between these two objectives. Countries, therefore, have to decide between lives and livelihoods. However, one year on since lockdowns swept the globe the evidence suggests that the trade-off between sacrificing lives and sacrificing the economy is not necessarily clear cut.

Controlling the virus

Restrictions such as social distancing and lockdowns were introduced in order to minimise the spread of the virus, prevent hospitals from being overwhelmed, and ultimately save lives. However, as these measures are put in place, schools were closed, businesses and factories stopped operating, and economic activity shrank. This would suggest therefore, that society inevitably faces a trade-off between lost lives versus lost livelihoods.

It could be argued, therefore, that in the short run these interventions create a ‘health–wealth trade-off’. The lockdown restrictions save lives by preventing transmission, but they came at the cost of lost output, income and therefore GDP. This would also imply that the trade-off works in reverse when the lockdown restrictions are eased. As measures are relaxed, the economy can begin to recover but at the cost of an increased threat of the virus spreading again.

What are the costs?

In order to work out if a trade-off exists and what costs are involved, there must be a monetary value placed on human life. While this may seem unethical, governments, civil courts, regulatory bodies and companies do it all the time. The very existence of the life insurance industry is testament to the fact that human lives can be measured in monetary terms. One approach to measuring valuing life, commonly used by economists who conduct cost-benefit analyses, is the ‘value of statistical life’. It measures the loss or gain that arises from changes in the incidence of death, by eliciting people’s willingness to pay for small reductions in the probability of death, or their willingness to accept compensation in exchange for tolerating a small increase in the chance of death. (see the blog Lockdown – again. Is it worth it?)

Take the example of a complete lockdown. The potential number of lives saved can be estimated based on infection and fatality rates estimated from epidemiological models. This can then be multiplied by value of statistical life to compute the monetary value of saved lives. If this number exceeds the economic costs of a complete lockdown, then we know that it is desirable.

The trade-off between lost lives versus the economy is often erroneously viewed as an all-or-nothing choice between complete lockdown versus zero restrictions. However, in reality, there is a continuum in stringency of restrictions and it is not an all-or-nothing comparison.

Death rates vs downturns

In order to explore the existence of this trade-off, we can compare the health and economic impacts of the pandemic in different countries. If such a trade-off exists, then countries with lower death rates should have experienced larger economic downturns. However, when comparing the COVID-19 death rates with GDP data, the result is the opposite: countries that have managed to protect their population’s health in the pandemic have generally also protected their economy too. This suggests that there was never a simple binary trade-off between the two factors. Those countries that experienced the biggest first wave of excess deaths, also had the biggest hits to the economy.

The UK was the hardest hit of similar countries on both measures within the G7 group of industrialised countries. The shape of the recession in the UK from the pandemic and lockdowns was extraordinary and historic. However, it was also unique as there was a very sharp fall followed by a rapid rebound. Over 2020, GDP saw the largest hit in three centuries; larger than any single year of the Great Wars or the 1920s Depression.

Studies of the declines in GDP contradict the idea of a trade-off, showing that countries that suffered the most severe economic downturns, such as Peru, Spain and the UK, were generally among the countries with the highest COVID-19 death rates. There are countries that have experienced the reverse too; Taiwan, South Korea, and Lithuania all experienced modest declines in economic output but have also managed to keep the death rate low.

It should also be noted that some countries that had similar falls in GDP experienced very different death rates from each other. When comparing the USA and Sweden with Denmark and Poland, they all saw similar declines in the economy with contractions of around 8–9%. However, the USA and Sweden recorded 5–10 times more deaths per million. This therefore suggests that there is no clear trade-off between the health of the population and the health of the economy.

There will be many different factors that impact on the death rate for each individual country and by how much the economy has been affected. Such factors will even go beyond the policy decisions that have been made throughout the pandemic about how best to suppress the transmission of the virus. However, from the data available, there is no clear evidence to suggest that a trade-off between the health and the economy exists. If anything, it suggests that the relationship works in the opposite direction.

Save the economy by saving lives

Given the arguments against the existence of the trade-off, it could be argued that in order to limit the economic damage caused by the pandemic, the focus needs to start and end with controlling the spread of the virus. Experiments that have been conducted across the world definitively show that no country can prevent the economic damage without first addressing the pandemic that causes it. Those countries that acted swiftly in implementing harsh measures to control the virus, are now reopening in stages and their economies are growing. Countries such as China, Australia, New Zealand, Iceland, and Singapore, which all invested primarily in swift coronavirus suppression, have effectively eliminated the virus and are seeing their economies begin to grow again.

China, in particular, stands out amongst this group of countries. The Chinese authorities acted very quickly, and firmly, but also the levels of compliance of the population have been very high. However, it could be argued that few countries possess the infrastructure that exists in China to facilitate such high compliance. The fact that the lockdown in China was so effective reduced both losses to the economy and the need for stimulus measures. China is also one of the few countries that have achieved a “V-shaped” recovery. Countries such as Korea, Norway and Finland also appear to have responded relatively well.

Most of the countries that prioritised supporting their economies and resisted, limited, or prematurely curtailed interventions to control the pandemic faced runaway rates of infection and further national lockdowns. The examples of the UK, the USA and Brazil are often quoted, with many arguing that these countries responded too late and too haphazardly. Both have experienced high numbers of deaths.

Conclusion

Discussions around the responses to the pandemic and what appropriate action should be taken have predominately been about how countries can strike the balance between protecting people’s health and protecting the economy. However, from observing the GDP data available there is no clear evidence of a definitive trade-off; rather the relationship between the health and economic impacts of the pandemic goes in the opposite direction. As well as saving lives, countries controlling the outbreak effectively may have adopted the best economic strategy too. It is important to recognise that many factors have affected the death rate and the impact on the economy, and the full impacts of the pandemic are yet to be seen. However, it is by no means clear that the trade-off between greater emphasis on sacrificing lives or sacrificing the economy is as real as has been suggested. If such a trade-off does exist, it is, at best, a weak one.

  2. Using your answer to question 1, describe the existence of a trade-off.
  3. Discuss the reasons why the trade-off between health and the economy would work in the opposite direction.

Private Finance Initiatives were first introduced by the Conservatives in the early 1990s and they became a popular method of funding a variety of new public projects under New Labour. These included the building of prisons, new roads, hospitals, schools etc. The idea is that a private firm funds the cost and maintenance of the public sector project, whilst the public sector makes use of it and begins repaying the cost – something like a mortgage, with contracts lasting for about 30 years. As with a mortgage, you are saddled with the payments and interest for many years to come. This is the problem now facing many NHS trusts, who are finding it too expensive to repay the annual charges to the PFI contractors for building and servicing the hospitals.

Undoubtedly, there are short term benefits – the public sector gets a brand new hospital without having to raise the capital, but in the long term, it is the public who end up repaying more than the hospital (or the PFI project) is actually worth. Data suggests that a hospital in Bromley will cost the NHS £1.2 billion, which is some 10 times more than it is worth. Analysis by the Conservatives last year suggested that the 544 projects agreed under Labour will cost every working family in the UK about £15,000. This, compared with the original building cost of £3,000, is leading to claims that the PFI projects do not represent ‘value for money.’

More and more NHS trusts are contacting Andrew Lansley to say that the cost of financing the PFI project is undermining their ‘clinical and financial stability’. More than 60 hospitals and 12 million patients could be affected if these hospitals are forced to close. Health Secretary Andrew Lansley commented that:

‘Like the economy, Labour has brought some parts of the NHS to the brink of financial collapse.’

Labour, on the other hand, argue that the PFI contracts they created were essential at the time ‘to replace the crumbling and unsafe building left behind after years of Tory neglect.’ Although the public have benefited from the development of new hospitals, schools, roads etc, the long term costs may still be to come. Once the schemes are paid off, in 2049, over £70billion will have been paid to private contractors – significantly more than the cost and value of the projects and it will be the taxpayer who foots the bill.

Cement may be quietly emerging as one of the biggest obstacles to lowering carbon emissions to reduce the extent of global warming. The cement industry rarely features in media analysis of the ‘worst polluters’, but in fact the industry is responsible, because of the high energy requirements of manufacture, for more than 5% of carbon dioxide emissions. A building boom globally has fuelled demand for the material. Concrete is the second most used product on the planet, after water, so what can be done to reduce the impact of the industry on the environment?
