The debate on whether or not there are long cycles in economic
development has been going on for almost a century. Supporters
of the theory of long cycles argue that capitalism follows
a cycle of 40 to 60 years duration, with different phases.
Braudel proposes that there is an even longer cycle of 150–350
years – la longue durée – that can be traced back to the Middle
Ages. Critics maintain that the different historical-economic
segments of past cycles are in fact caused by random variations
and major political events that cannot be predicted in advance.
The topic of this essay relates to an ongoing Swedish economic-historical
discussion concerning long-term structural change. The chief
representative of the theory of long cycles in Sweden is the
economic historian Lennart Schön, although his structural economic
cycle model differs from established international theories
of long cycles. Schön describes the Swedish economic development
since the industrial breakthrough as an alternation between
transformation phases of 20–25 years and rationalization phases
of 15–20 years. He also suggests that there may be even longer
cycles. This essay analyzes the emergence of the Swedish structural
economic cycle model. The model has largely been developed
in isolation from the international debate, despite recent
claims by Schön that it is also relevant for the world economy.
Its advocates have also shifted between which structural indicators
that should be used to claim support for its periodisation.
