How have earnings behaved on this context of sustained stage of inflation? Partly, the reply is dependent upon how ‘earnings’ are outlined. Some broad measures counsel rising earnings, however conflate market and non-market sector dynamics and omit vital company prices. We assemble another measure of company earnings to seize UK agency earnings in extra of all manufacturing prices. This measure has been declining for the reason that begin of 2022, in step with proof from historic power shocks. This decline has not been uniform throughout corporations, nevertheless: corporations with larger market energy have been higher capable of enhance their margins; others have skilled giant declines.
Earnings versus extra earnings: measurement and tendencies
Measuring earnings is a difficult process: nationwide accounts information are affected by the ‘combined revenue’ of self-employed, taxes and subsidies, and conflate two completely different dynamics: these of the market and non-market (actual property and public) sectors.
We deal with the company sector and exclude self-employed and non-market sectors. That is much like the measure utilized in Haskel (2023), however in distinction to IMF and ECB work that focuses on the overall economic system. We moreover summary from the position of taxes and subsidies; as Haskel (2023) factors out, they play a big position within the latest interval. We thus deal with company gross worth added (GVA, at issue prices) and initially break up this into two elements: worker compensations and ‘earnings’, ie all the pieces that’s left after paying staff, ie company ‘gross working surplus’ (GOS).
We then go additional, following Barkai (2019), and decompose ‘earnings’ into two elements:
- Capital compensations, which seize corporations’ value of capital (eg the prices of sustaining the gear and repaying the debt used to buy it). Following the Corridor and Jorgensen (1967) system, we measure these prices because the sum of capital depreciation, modifications in its substitute value, and the chance value of holding bodily reasonably than monetary capital captured via 10-year authorities bond yields.
- ‘Extra’ or, as Barkai (2020) calls it, ‘pure’ earnings, ie what a agency earns in extra of all manufacturing prices (together with not simply labour prices, but in addition the price of holding and sustaining the capital enter). The share of extra earnings in company GVA (which captures the worth a agency units relative to its common prices) is the closest idea in nationwide accounts to the measure of mark-ups estimated in firm-level information (which captures the worth a agency units relative to its marginal prices).
We begin in Chart 1 by tendencies within the shares of labour and earnings in company GVA since 2015, and decompose the revenue share additional into capital/extra revenue shares. The revenue share is broadly flat over the interval, suggesting the IMF and ECB outcomes mirror partially non-corporate sector dynamics, in step with the findings in Haskel (2023). When decomposing this share into capital and extra revenue components, we will see extra earnings elevated in 2021 through the speedy post-lockdown demand restoration, in step with mark-ups rising through the excessive demand Covid restoration interval. They began to say no, nevertheless, in 2022, when the Ukraine warfare began. This fall in extra earnings partly displays larger capital prices for corporations who are actually experiencing larger curiosity funds to service their debt (on account of rising rates of interest since start-2022).

Similarities and variations between present and previous power shocks
In Chart 2.a, we evaluate the evolution of those shares within the 2022 episode to the oil shocks within the Seventies. In Chart 2.b, we formalise the comparability utilizing a regression framework to estimate the common response of corporations’ earnings and mark-ups following power provide shocks over the interval 1984–2022 (see Technical appendix for particulars). We use the oil-supply information shock collection from Kanzig (2021) as our measure of an power shock, recognized through the response of oil-price futures in slim home windows round OPEC+ bulletins.
Chart 2.b (high panel) describes the responses of labour, capital, and extra revenue shares to the recognized power shock. Chart 2.b (backside panel) estimates the impression on firm-level mark-ups, which is closest in idea to our measure of extra earnings within the nationwide accounts. We lack granular information on corporations’ mark-ups for the reason that onset of the Russia–Ukraine warfare, however Haldane et al (2018) estimate mark-ups for all UK-listed corporations utilizing information over 1987–2018 from Worldscope. The chart reveals the estimated response of common (detrended) mark-ups, weighted by corporations’ UK gross sales.

Notes: Authors’ calculations utilizing ONS information. The black vertical line denotes quarter 5 after the shock.
Chart 2.b: Estimated impulse responses of extra revenue, capital and labour shares (high panel) and mark-ups (backside panel) following a ten% enhance in oil costs
Notes: Estimated impulse responses to power shocks, utilizing native projections (see Technical appendix). Outcomes for extra revenue, labour and capital shares estimated on quarterly information 1984 This fall–2022 This fall. Outcomes for mark-ups estimated on annual information 1987–2018. Dashed strains denote 90% confidence intervals.
There are two predominant takeaways from this comparability:
- The labour/revenue share response within the 2022 episode is completely different from the Seventies however much like more moderen power shocks.
Within the Seventies, the labour share elevated within the first couple of years adopted by a decline within the following years. The rise and fall within the labour share was, on the time, thought to mirror the failure of wages to regulate to the adversarial provide shocks within the brief run (Blanchard et al (1997)). In line with this story, this sample was stronger in nations with extra inflexible labour markets, reminiscent of continental Europe and Japan. Blanchard et al (1997) additionally counsel that whereas the preliminary impact of the shock was to lower the revenue share, over time corporations reacted by shifting away from labour, resulting in a gradual enhance in unemployment in addition to a restoration, and even a rise, in revenue shares.
Against this, the labour share is broadly flat in each the 2022 episode and within the native projection outcomes masking the interval 1984–2022. This would possibly counsel a distinct labour market now than within the Seventies, after labour market reforms passed off within the Eighties.
- The surplus revenue share and mark-ups lower throughout all power shocks, together with that in 2022.
All shocks exhibit a major decline within the extra revenue share within the first three years. The surplus revenue share declines by about 0.7 pp on the peak following a ten% oil worth enhance within the native projections; it suggests a 14 pp decline following the 200% worth enhance noticed in 1973. By comparability, we observe a peak decline of 20 pp in extra revenue after the 1973 oil shock, so the responses are of comparable magnitude. Over the 5 quarters 2022 Q1–2023 Q1, we observe a 3.5 pp decline within the share. Whereas the magnitude may appear smaller this time, the shock can be smaller (40% oil worth enhance), and the federal government launched assist schemes to melt the impression. Word that the falling extra revenue share displays a minimum of partially the rise in rates of interest – an vital element of the price of capital that rises throughout all episodes.
This fall additionally happens for the common mark-up. The mark-up falls considerably in response to the power shock with the height response in 12 months two (by round 0.8 pp), the place each the magnitude and time-profile of the response is remarkably much like our findings for the surplus revenue share. Finally it’s mark-ups that matter for inflation, as inflation is proximately pushed by modifications in marginal prices and modifications in mark-ups (over these marginal prices) desired by corporations.
Totally different responses throughout sectors and corporations
The mixture fall in mark-ups masks vital heterogeneity throughout sectors: mark-ups rise considerably within the mining and quarrying sector (pushed by oil and fuel extraction corporations), in addition to in another sectors (eg wholesale and retail) – Chart 3.
Chart 3: Estimated response of mark-ups by section-level business on the one-year horizon
Notes: Dots present estimated response of mark-ups to an power shock for every business on the one-year horizon, bands are 90% conf intervals utilizing Driscoll-Kraay normal errors. See Technical appendix for extra particulars.
We lengthen our native projection framework and work together the mark-up response with corporations’ traits. We discover that, within the 12 months after the power shock, mark-ups rise by extra (fall by much less) for corporations which might be: (i) in additional concentrated industries; (ii) much less energy-intensive; and (iii) have much less sticky costs.
We mix real-time firm-level information from the Choice Maker Panel (DMP) Survey with corporations’ balance-sheet information to research these agency heterogeneities within the latest interval. We lack the required info to estimate mark-ups. As a substitute, we deal with web working revenue share in gross sales. Regardless of some conceptual variations, this measure is closest to the idea for GOS share in gross worth added (revenue share, together with each capital and extra revenue), and the 2 measures commove strongly for the reason that mid-Nineteen Nineties.
We examine how earnings evolve for the common DMP agency, and the way they rely on agency traits. We discover that corporations within the DMP skilled a small decline in margins for the reason that begin of the Ukraine warfare (Chart 4). This contrasts with ONS gross revenue measure (gray line in Chart 1) that reveals a flat revenue share over 2022–23. This could possibly be associated to the broad pattern of corporations within the DMP; eg there are often few respondents from the oil sector, the place earnings have a tendency to extend considerably following an oil shock.
In line with the native projections, we see that earnings have been extra negatively affected for corporations in high-energy intensive industries, and fewer negatively affected for corporations in additional concentrated industries. The DMP additionally asks in regards to the significance of competitor costs for pricing choices. Companies that reply that opponents’ pricing is among the many most vital issue for his or her worth determination often exhibit a decrease decline in margins, however the significance is delicate to the specification.
Chart 4: Modifications in agency revenue margins within the DMP conditional on sector/agency traits
Notes: The outcomes on revenue margins are primarily based on the query: ‘Within the first quarter of 2023 (January to March), what was your approximate ‘working revenue margin’ (in proportion phrases)? And what was it one 12 months in the past, within the first quarter of 2022?’. Power depth is estimated utilizing business information on power prices from ONS Provide and Use Tables. Trade focus is measured utilizing a Herfidahl-Hirschman Index on the SIC2 stage. The outcomes are weighted by employment and business shares.
Technical appendix: particulars on the native projection train
In the primary submit, we use native projection regressions to estimate the response of varied consequence variables to power shocks. First, we estimate the response of a variety of mixture time-series information via the next native projection:
the place is the h-period forward cumulative change within the consequence variable of curiosity (eg the revenue share), εt is a measure of an power provide shock (which we take from Kanzig (2021)), and Xt are (lagged) management variables together with lags of the dependent variable and different variables capturing the state of the macroeconomy (eg GDP and inflation). Estimates of βh from equation (1) for the labour, capital and extra revenue shares, and mixture (detrended) mark-ups are proven in Chart 2.b in the primary submit.
We then estimate panel native projections to check the response of corporations’ mark-ups at a extra granular stage. First we estimate the next regressions for subsets of corporations in every section-level business S:
We then gather and plot the one-year sector-specific mark-up responses to spotlight the heterogeneity throughout sectors (Chart 3 in the primary submit).
Subsequent, we lengthen equation (2) to research the drivers of this heterogeneity:
the place 𝑍𝑖,𝑡 is a vector capturing a variety of potential drivers of heterogeneity in corporations’ mark-up response to power shocks. Desk A plots the coefficients for the estimated interplay phrases δh on the one-year horizon, the place we take a look at for all potential sources of heterogeneity concurrently. We discover vital proof that mark-ups rise by extra (fall by much less) for corporations which might be: (i) in additional concentrated industries (as measured by the Herfindahl–Hirschman index from Savagar et al (2021)) ; (ii) much less energy-intensive (primarily based on corporations’ intermediate consumption of power items); and (iii) have much less sticky costs (primarily based on corporations’ reported frequency of worth modifications).
