The Impact of the Russian Invasion of Ukraine on the UK Economy

Question 1: Relative to the Bank of England’s planned trajectory for interest rates at the beginning of the year, the Bank should respond to geopolitical events by:

Answer:
Raising interest rates more rapidly
Confidence level:
Confident
Comment:
The bottom line is that inflation in February 2022 was 6.2%. The Bank of England can argue as much as it wants that it should “look through” transitory inflation but the optics of not responding to such high inflation do not look good. It’s the first time the inflation targeting framework has been tested on the upside, so a mild increase in the speed of tightening is warranted to signal commitment to bringing inflation down.

Surging Inflation in the UK

Question 2: Will the inflation surge of 2021 prove persistent?

Answer:
Uncertain or no opinion
Confidence level:
Confident
Comment:
The inflationary pressures from Covid-19 supply constraints should have largely eased by 2023. That leaves the future of inflation in the hands of monetary and fiscal policy, and the ability of policymakers to make the right judgements. Getting back to 4% inflation in 2023 is a tough call – it’s right at the level predicted by the inflation forward curve on UK gilts. I don’t think even the most optimistic policymaker would bet the house on inflation falling below 4% by 2023.

Question 1: Which of the following factors is the primary reason for the rise in inflation in 2021?

Answer:
Supply constraints
Confidence level:
Very confident
Comment:
The supply side of the UK economy has been compromised during the Covid-19 pandemic. It has been a large shock, and relative prices need to change for the market mechanism to redirect resources to where they are most productive. Since it is easier to raise prices than lower them, prices overall will rise and inflation will result. Although I believe that supply constraints were the primary reason for high inflation in 2021, it was pleasing to see that supply was more resilient than I feared it might be when the pandemic began.

Towards a High-Wage, High-Productivity Economy

Question 2: What is your evaluation of the following statement: “A well-designed government-stipulated wage increase can lead to higher productivity”?

Answer:
Strongly disagree
Confidence level:
Very confident
Comment:
“Well-designed” is doing a lot of heavy lifting in the statement. It’s uncertain whether any government-stipulated wage increase can lead to higher productivity, however well designed, and it’s certain that any attempt to exploit such a possibility will be badly designed. We simply do not understand enough about how a government-mandated wage increase affects productivity to start exploiting that relationship.

Question 1: Which of the following statements most closely reflects your understanding of the relationship between productivity and wages.

Answer:
Wage increases cannot increase productivity in and of themselves
Confidence level:
Very confident
Comment:
It is difficult to see a compelling causal mechanism running from higher aggregate wages to higher productivity in the UK, when the converse is so obviously attractive. There are clever models in which low wages discourage effort (e.g. the effort of workers in their jobs or the efforts of employers to automate or invest in their workforce) but at the aggregate level these feel like exercises in “rationalising apparently puzzling behaviour” that economists are attracted to. Remember the largely now debunked “expansionary fiscal contractions”? Raising wages to improve productivity looks like falling into the fallacy of reverse causality. History is unlikely to look kindly on such initiatives.
