Business Cycles
Schumpeter's relationships with the ideas of other economists were quite complex in his most important contributions to economic analysis – the theory of business cycles and development. Following neither Walras nor Keynes, Schumpeter starts in The Theory of Economic Development with a treatise of circular flow which, excluding any innovations and innovative activities, leads to a stationary state. The stationary state is, according to Schumpeter, described by Walrasian equilibrium. The hero of his story is the entrepreneur.
| Proposed Economic Waves | |
|---|---|
| Cycle/Wave Name | Years |
| Kitchin inventory | 3–5 |
| Juglar fixed investment | 7–11 |
| Kuznets infrastructural investment | 15–25 |
| Kondratiev wave | 45–60 |
| Grand supercycle | 70+ |
The entrepreneur disturbs this equilibrium and is the prime cause of economic development, which proceeds in cyclic fashion along several time scales. In fashioning this theory connecting innovations, cycles, and development, Schumpeter kept alive the Russian Nikolai Kondratiev's ideas on 50-year cycles, Kondratiev waves.
Schumpeter suggested a model in which the four main cycles, Kondratiev (54 years), Kuznets (18 years), Juglar (9 years) and Kitchin (about 4 years) can be added together to form a composite waveform. Actually there was considerable professional rivalry between Schumpeter and Kuznets. The wave form suggested here did not include the Kuznets Cycle simply because Schumpeter did not recognize it as a valid cycle. See "Business Cycle" for further information. A Kondratiev wave could consist of three lower degree Kuznets waves. Each Kuznets wave could, itself, be made up of two Juglar waves. Similarly two (or three) Kitchin waves could form a higher degree Juglar wave. If each of these were in phase, more importantly if the downward arc of each was simultaneous so that the nadir of each was coincident it would explain disastrous slumps and consequent depressions. As far as the segmentation of the Kondratiev Wave, Schumpeter never proposed such a fixed model. He saw these cycles varying in time – although in a tight time frame by coincidence – and for each to serve a specific purpose.

Famous quotes containing the words business and/or cycles:
“I do not claim that all women, or a large portion of them, should enter into independent business relations with the world, but I do claim that all women should cultivate and respect in themselves an ability to make money.”
—Ellen Demarest (1824–1898)
“The stars which shone over Babylon and the stable in Bethlehem still shine as brightly over the Empire State Building and your front yard today. They perform their cycles with the same mathematical precision, and they will continue to affect each thing on earth, including man, as long as the earth exists.”
—Linda Goodman (b. 1929)
