Business Cycles: History, Theory and Investment Reality
Tvede on how credit and business cycles drive asset prices.
Summary
Tvede, a Danish investor and writer, surveys the intellectual history of business cycle theory and connects it to investment practice. The historical section covers the economists who built the field, from John Law and Cantillon through Juglar, Jevons, Mitchell, Schumpeter, Kondratieff, Keynes, Hayek and later work on real business cycles.
His synthesis identifies several cycles operating at different frequencies simultaneously: an inventory cycle of roughly three to five years, a capital expenditure cycle of seven to eleven years, a property and construction cycle of around eighteen to twenty years, and the long Kondratieff wave whose existence is disputed. He argues that the interaction of cycles operating at different lengths explains why no single cycle is clearly visible in the data.
The investment section maps asset classes onto cycle phases: which sectors lead a recovery, when bonds outperform equities, how commodities behave late in an expansion, and which indicators lead and lag. He gives specific attention to inventories, to the yield curve, to money supply and to construction starts as leading indicators.
The book is a survey rather than an original contribution, and it is more useful as an organised introduction to the literature than as a source of investment method. The Kondratieff material is the weakest part, since the long wave's existence is not established and Tvede treats it as more solid than the evidence supports. The specific indicator relationships are drawn from a period whose monetary regime has changed.
Key takeaways 7
- Several economic cycles of different lengths operate simultaneously, which is why no single clean cycle appears in the data.
- The inventory cycle of three to five years is the most reliably observable, because inventory adjustment amplifies small demand changes.
- The property and construction cycle runs roughly eighteen to twenty years, driven by the long lag between a decision to build and the completed supply.
- Different asset classes and sectors lead and lag at identifiable points in the cycle, which makes rotation a usable strategy if the phase can be identified.
- The yield curve, money supply growth and construction starts have historically led turning points, while employment and earnings lag them.
- Capital investment cycles are self-reinforcing because investment creates the demand that justifies further investment until capacity exceeds it.
- Business cycle theory has been dominated by disputes between monetary, real and psychological explanations, and each captures part of an interacting process.
Who should read it
Investors who want an organised survey of business cycle theory connected to asset class behaviour, read as introduction rather than as method.
