Should central bank targets be changed?

Central bankers, policymakers, academics and economists met at the Economic Symposium at Jackson Hole, Wyoming from August 24–26. This annual conference, hosted by Kansas City Fed, gives them a chance to discuss current economic issues and the best policy responses. The theme this year was ‘Structural Shifts in the Global Economy’ and one of the issues discussed was whether, in the light of such shifts, central banks’ 2 per cent inflation targets are still appropriate.

Inflation has been slowing in most countries, but is still above the 2 peer cent target. In the USA, CPI inflation came down from a peak of 9.1% in June 2022 to 3.2% in July 2023. Core inflation, however, which excludes food and energy was 4.7%. At the symposium, in his keynote address the Fed Chair, Jay Powell, warned that despite 11 rises in interest rates since April 2022 (from 0%–0.25% to 5%–5.25%) having helped to bring inflation down, inflation was still too high and that further rises in interest rates could not be ruled out.

We are prepared to raise rates further if appropriate, and intend to hold policy at a restrictive level until we are confident that inflation is moving sustainably down toward our objective.

However, he did recognise the need to move cautiously in terms of any further rises in interest rates as “Doing too much could also do unnecessary harm to the economy.” But, despite the rises in interest rates, growth has remained strong in the USA. The annual growth rate in real GDP was 2.4% in the second quarter of 2023. Unemployment, at 3.5%, is low by historical standards and similar to the rate before the Fed began raising interest rates.

Raising the target rate of inflation?

Some economists and politicians have advocated raising the target rate of inflation from 2 per cent to, perhaps, 3 per cent. Jason Furman, an economic policy professor at Harvard and formerly chief economic advisor to President Barack Obama, argues that a higher target has the benefit of helping cushion the economy against severe recessions, especially important when such there have been adverse supply shocks, such as the supply-chain issues following the COVID lockdowns and then the war in Ukraine. A higher inflation rate may encourage more borrowing for investment as the real capital sum will be eroded more quickly. Some countries do indeed have higher inflation targets, as the table shows.

Powell emphatically ruled out any adjustment to the target rate. His views were expanded upon by Christine Lagarde, the head of the European Central Bank. She argued that in a world of greater supply shocks (such as from climate change), greater frictions in markets and greater inelasticity in supply, and hence greater price fluctuations, it is important for wage increases not to chase price increases. Increasing the target rate of inflation would anchor inflationary expectations at a higher level and hence would be self-defeating. Inflation in the eurozone, as in the USA, is falling – it halved from a peak of 10.6% in 2022 to 5.3% in July this year. Given this and worries about recession, the ECB may not raise interest rates at its September meeting. However, Lagarde argued that interest rates needed to remain high enough to bring inflation back to target.

The UK position

The Bank of England, too, is committed to a 2 per cent inflation target, even though the inflationary problems for the UK economy are greater that for many other countries. Greater shortfalls in wage growth have been more concentrated amongst lower-paid workers and especially in the public health, safety and transport sectors. Making up these shortfalls will slow the rate of inflationary decline; resisting doing so could lead to protracted industrial action with adverse effects on aggregate supply.

Then there is Brexit, which has added costs and bureaucratic procedures to many businesses. As Adam Posen (former member of the MPC) points out in the article linked below:

Even if this government continues to move towards more pragmatic relations with the EU, divergences in standards and regulation will increase costs and decrease availability of various imports, as will the end of various temporary exemptions. The base run rate of inflation will remain higher for some time as a result.

Then there is a persistent problem of low investment and productivity growth in the UK. This restriction on the supply side will make it difficult to bring inflation down, especially if workers attempt to achieve pay increases that match cost-of-living increases.

Sticking to the status quo

There seems little appetite among central bankers to adjust inflation targets. Squeezing inflation out of their respective economies is painful when inflation originates largely on the supply side and hence the problem is how to reduce demand and real incomes below what they would otherwise have been.

Raising inflation targets, they argue, would not address this fundamental problem and would probably simply anchor inflationary expectations at the higher level, leaving real incomes unchanged. Only if such policies led to a rise in investment would a higher target be justified and central bankers do not believe that it would.

Questions

  1. Use an aggregate demand and supply diagram (AD/AS or DAD/DAS) to illustrate inflation since the opening up of economies after the COVID lockdowns. Use another one to illustrate the the effects of central banks raising interest rates?
  2. Why is the world likely to continue experiencing bigger supply shocks and greater price volatility than before the pandemic?
  3. With hindsight, was increasing narrow money after the financial crisis and then during the pandemic excessive? Would it have been better to have used the extra money to fund government spending on infrastructure rather than purchasing assets such as bonds in the secondary market?
  4. What are the arguments for and against increasing the target rate of inflation?
  5. How do inflationary expectations influence the actual rate of inflation?
  6. Consider the arguments for and against the government matching pay increases for public-sector workers to the cost of living.
