There are currently at least two advantages to being a former academic sociologist in my early fifties: I'm just about old enough to remember the high and accelerating inflation of the mid 1970s, and I’m able to recognise the limitations of a purely economic theory of inflation.
Two things have prompted these musings on inflation. Firstly, encountering price increases on basic foodstuffs at one of the main discount supermarkets in the UK (500g bran flakes up from 46p to 49p, sardines from 31p to 35p), the daily reality of CPI inflation recorded at 5.5% in January 2022. See UK CPI data.
Secondly, reading a thoughtful essay on inflation, ‘The Perils of Yesterday’s Logic’, by Henry Maxey in the investment house Ruffer’s recently published Annual Review.
Maxey’s essay reminded me of Milton Friedman’s famous observation that “inflation is always and everywhere a monetary phenomenon”, (p181 in The Counter-Revolution in Monetary Theory).
Maxey also references a powerful intellectual counterargument to Friedman co-edited by couple of authors I read as an undergraduate, namely Fred Hirsch and John Goldthorpe’s 1978 collection of papers The Political Economy of Inflation.
The book was based on a 1977 conference at the University
of Warwick where several non-economists brought wider social science insights
to bear on a topic too important to be left to rival schools of economists.
Put simply, contra Friedman, inflation is always and
everywhere a social phenomenon.
Maxey highlights Hirsch’s argument that inflation becomes pronounced when the status order of a society is in question: “containment of the latent distributional struggle without financial instability requires either sufficient authority or sufficient consensus, on the values or principles underlying the distribution of income and other aspects of welfare. If established authority weakens before a sufficient consensus or a new authority emerges, inflation results.”
Who can doubt that the advanced economies of 2022 lack
both authoritative leadership and widespread social consensus?
The
level of prices, and their rate of growth depends on a complex ever-changing
balance of forces on both the demand and supply sides of economic transactions,
between producers and consumers, workers and employers, companies and
regulators, politicians and electorates. This balance of forces is being
profoundly disrupted in early 2022, with inflation one consequence (and itself
a further source of disruption if persistent).
The acceleration or otherwise of inflation
ultimately depends on the ability and willingness of people to pay for goods
and services, and these are not simply determined by resource constraints, but are
shaped by contestable definitions of social acceptability. Is it acceptable for
companies to pass on cost increases? Will employees accept wage increases below
the rate of inflation? Will consumers accept having to trade down as prices rise, or will they
continue to accept higher prices to access favoured brands?
Hirsch’s notion of status order is well-chosen for it invokes Max Weber’s classic sociological definition of status as "the social estimation of honour".
Quantitative indicators such as the prices of goods and thereby the rate of inflation are the translation into numbers of social transactions where the numerical outcomes have processed through estimations of honour, decency and social and political acceptability.
Prices embody both economic and social contracts.
The limits to inflation are set by how
far people will tolerate the stretching of their definitions of what can be
socially as well as financially afforded, and the extent to which what J.K. Galbraith termed ‘countervailing power’ can be mobilised and exerted against the pressures of rising prices.
This is why inflation is always and
everywhere a social phenomenon.
In the meantime, I will enter supermarkets
with renewed trepidation and reach for the few 1980s economic textbooks I didn’t
throw out to remind me of ‘demand-pull’, ‘cost-push’, and other parts of the
lost language of high inflation which are likely to prove useful in the days
ahead.
