A level Economics: UK's inflation is due to rise in corporate profit-taking

Figures give fuel to claims that profiteering has played a big part in the UK’s high levels of inflation writes Phillip Inman in The Guardian 


British companies have boosted their profitability, according to the latest official figures, insulating themselves against cost pressures and fuelling claims that profiteering has played a big part in the UK’s inflation story.

In a week when Joe Biden said he was only winning the war against inflation in the US because corporate profits were declining, figures released on Thursday by the Office for National Statistics showed UK business profits increased in the first quarter of 2023.

Manufacturing firms increased their net rate of return to 8.8% in the first quarter, from 8.4% in the fourth quarter of 2022. Services companies, which account for about three-quarters of economic activity, increased their net rate of return to 16.1%, an increase of 0.4 percentage points from the last three months of 2022.

The rate of return is a measure of profitability that shows the margin between operating profits and the cost of assets used to generate those profits. Unions have accused firms of putting up prices by more than the rise in their costs, a trend nicknamed greedflation.

It is a hot topic because the Bank of England has consistently said the small ups and downs registered by the ONS in its calculations of corporate profitability show little evidence of profiteering. It has repeatedly urged workers to restrain wage demands and played down the need to tell companies to restrain price rises.

On the other side of the argument stand a growing number of academics, thinktanks and unions.

The TUC general secretary, Paul Novak, said he was shocked by the ONS figures, which he claimed showed “a culture of entitlement is alive and well” among the large corporations that he said were mostly to blame for higher prices.

Sharon Graham, the head of the Unite union, arguably credited with doing more than anyone in the UK to promote research into corporate profits, said companies were exploiting a crisis.

Philip King, a former government adviser and small business commissioner until 2021, said many small and medium-sized companies would wonder what the fuss was about. He said it was clear from the figures that “companies are maintaining their profitability despite the difficult trading conditions they have faced”, and it was large businesses that would be to blame. These “typically have more flexibility when it comes to increasing prices and cutting costs”, he said.

The International Monetary Fund (IMF), the Organisation for Economic Co-operation and Development (OECD) and many leading academics say steady profit margins show businesses are doing better than any other participants in the economy, in particular workers.

An OECD report last month found average profit margins in the UK increased by almost a quarter between the end of 2019 and early 2023. Stefano Scarpetta, a director of the OECD, said it was “somewhat unusual that in a period of slowdown in economic activity we see profit picking up”.

George Dibb, an economist at the IPPR thinktank, said the Bank of England was “plain wrong” to consider steady profit margins a non-story.

On closer inspection the headline average is if anything worse than it first appears. Overall, the net rate of return for all non-financial businesses – a measure that excludes banks and insurance companies but includes North Sea oil and gas firms – increased from 9.8% in the last quarter of 2022 to 9.9% in the first quarter. That shows margins remained consistent through one of the worst winters for cost of living rises and cuts in disposable incomes for several generations.

However, excluding North Sea oil and gas firms, which showed a slump in profitability in the first quarter as energy prices fell from their peaks, dragging down the average, the level of profitability for most firms jumped from 9.6% in the last quarter of 2022 to 10.6% in the first quarter of 2023.

Richard Murphy, a professor of accounting at the University of Sheffield, said low wage rises in most sectors outside financial services meant large companies were probably doing much better than smaller ones.

Murphy said half of all UK company profits were generated by small and medium-sized companies and the other half by a few thousand larger firms.

Another interest rate rise is expected next month and the main reason given by the Bank will be that wages are rising too quickly, not that profits are rising too quickly. It is a stance that is going to become increasingly contentious.

Economics for Dummies: Unveiling the Truth Behind Government Claims on Inflation

ChatGPT

Inflation, a ubiquitous economic phenomenon, wields a significant impact on the purchasing power of individuals and the stability of economies. Governments often tout their achievements in taming inflation, but a deeper examination reveals a nuanced reality. This essay explores the intricacies of inflation, clarifies the deceptive nature of government claims regarding inflation reduction, and provides illustrative examples to shed light on the distinction between inflation rates and actual price changes.

The Inflation Mirage: When governments proudly announce the reduction of inflation from 10% to 5%, it is not a declaration of falling prices but rather a claim of moderating the rate at which prices increase. Inflation is not a direct measure of price levels but a gauge of how quickly those levels are changing. Imagine a roller coaster; if it slows down from an extreme speed to a slower one, it is not moving backward, merely decelerating its forward motion.

Understanding the Steps: To comprehend the mechanics, consider a hypothetical good priced at £1 at the end of 2021. If the inflation rate for 2022 is 10% and 5% for 2023, the price evolution can be broken down into stages.

Step 1: 2022 Inflation Price at the end of 2021 = £1 Inflation in 2022 = 10% Price after 2022 inflation = £1 * (1 + 0.10) = £1.10

Step 2: 2023 Inflation Price after 2022 inflation = £1.10 Inflation in 2023 = 5% Price after 2023 inflation = £1.10 * (1 + 0.05) = £1.155

The Price Illusion: Governments' claims of lowering inflation from 10% to 5% create an illusion of prices falling. However, the reality is that while the rate of price increase has slowed down, prices are still ascending. This can be compared to a marathon runner who has reduced their speed; they are still moving forward, just not as swiftly as before.

Deconstructing Government Claims: Governments may employ such claims for various reasons, including instilling confidence in economic policies or promoting their efforts to stabilize the economy. However, this communication can lead to misunderstanding and misinterpretation by the public. For instance, an individual may perceive a 5% inflation rate as a signal to expect a decrease in their expenses, only to find that their cost of living continues to rise, albeit at a slightly slower pace.

Examples:

1. Real Estate: If a government announces a reduction in inflation from 10% to 5%, potential homebuyers might anticipate lower house prices. However, the reality could be that property prices are still increasing, but at a diminished rate. This could affect individuals' decisions regarding homeownership and mortgage commitments.

2. 
   

3. Consumer Goods: A consumer who witnesses a lower inflation rate might believe that their monthly grocery bills will decrease. Yet, the prices of essential commodities may still be rising, putting pressure on their household budget.

The distinction between inflation rates and actual price changes is a crucial concept that citizens must grasp to make informed financial decisions. Governments' claims of lowering inflation, while important for economic stability, should not be misconstrued as a signal of falling prices. Recognizing the difference between a decrease in the rate of price escalation and a true decline in prices is pivotal in navigating the complex landscape of personal finance and economic planning.
