In economics, Kondratiev waves (also called supercycles, great surges, long waves, K-waves or the long economic cycle) are hypothesized cycle-like phenomena in the modern world economy.The term long wave originated from a poor early translation of long cycle from Russian to German. Freeman, Chris; Louçã, Francisco (2001) pp 70 The phenomenon is closely connected with the technology life cycle.
It is stated that the period of a wave ranges from forty to sixty years, the Economic cycle consist of alternating intervals of high sectoral Economic growth and intervals of relatively slow growth.See, e.g.
Long wave theory is not accepted by most academic economists. Among economists who accept it, there is a lack of agreement about both the cause of the waves and the start and end years of particular Wave. Among critics of the theory, the consensus is that it involves recognizing patterns that may not exist (apophenia).
Two Dutch economists, Jacob van Gelderen and Salomon de Wolff, had previously argued for the existence of 50- to 60-year cycles in 1913 and 1924, respectively.
Since the inception of the theory, various studies have expanded the range of possible cycles, finding longer or shorter cycles in the data. The Marxist scholar Ernest Mandel revived interest in long-wave theory with his 1964 essay predicting the end of the long boom after five years and in his Alfred Marshall lectures in 1979. However, in Mandel's theory long waves are the result of the normal business cycle and noneconomic factors, such as wars.
In 1996, George Modelski and William R. Thompson published a book documenting K-Waves dating back to 930 AD in China. Separately, Michael Snyder wrote: "economic cycle theories have enabled some analysts to correctly predict the timing of recessions, stock market peaks and stock market crashes over the past couple of decades".
The historian Eric Hobsbawm also wrote of the theory: "That good predictions have proved possible on the basis of Kondratiev Long Waves—this is not very common in economics—has convinced many historians and even some economists that there is something in them, even if we don't know what".Hobsbawm (1999), pp. 87f.
US economist Anwar Shaikh analyses the movement of the general price level - prices expressed in gold - in the US and the UK since 1890 and identifies three long cycles with troughs ca. in 1895, 1939 and 1982. With this model 2018 was another trough between the third and a possible future fourth cycle.Anwar Shaikh 2016: Capitalism. Oxford University Press. P. 749.
Writing in the 1920s, Kondratiev proposed to apply the theory to the 19th century:
The long cycle supposedly affects all sectors of an economy. Kondratiev focused on and , seeing the ascendant phase as characterized by an increase in prices and low interest rates while the other phase consists of a decrease in prices and high interest rates. Subsequent analysis concentrated on output.
In recent decades there has been considerable progress in historical economics and the history of technology, and numerous investigations of the relationship between technological innovation and economic cycles. Some of the works involving long cycle research and technology include Mensch (1979), Andrew Tylecote (1991), the International Institute for Applied Systems Analysis (IIASA) (Marchetti, Ayres), Freeman and Louçã (2001), Andrey Korotayev and Carlota Perez.
Perez (2002) places the phases on a logistic or S curve, with the following labels: the beginning of a technological era as irruption, the ascent as frenzy, the rapid build out as synergy and the completion as maturity.
The theory was developed by Irving Fisher following the Wall Street Crash of 1929 and the ensuing Great Depression. Debt deflation was largely ignored in favor of the ideas of John Maynard Keynes in Keynesian economics, but it has enjoyed a resurgence of interest since the 1980s, both in mainstream economics and in the heterodox school of post-Keynesian economics and has subsequently been developed by such post-Keynesian economists as Hyman Minsky and Steve Keen.
Additionally, there are several versions of the technological cycles and they are best interpreted using diffusion curves of leading industries. For example, railways only started in the 1830s, with steady growth for the next 45 years. It was after Bessemer steel was introduced that railroads had their highest growth rates. However, this period is usually labeled the age of steel. Measured by value added, the leading industry in the U.S. from 1880 to 1920 was machinery, followed by iron and steel. Table 7: Ten leading industries in America, by value added, 1914 prices (millions of 1914 $'s)
Any influence of technology during the cycle that began in the Industrial Revolution pertains mainly to England. The U.S. was a commodity producer and was more influenced by agricultural commodity prices. There was a commodity price cycle based on increasing consumption causing tight supplies and rising prices. That allowed new land to the west to be purchased and after four or five years to be cleared and be in production, driving down prices and causing a depression as in 1819 and 1839. By the 1850s, the U.S. was becoming industrialized.See: Joseph Whitworth's quote under American system of manufacturing#Use of machinery.
The technological cycles can be labeled as follows:
Some argue that this logic can be extended. The custom of classifying periods of human development by its dominating general purpose technology has surely been borrowed from historians, starting with the Stone Age. Including those, authors distinguish three different long-term meta, each with different long waves. The first focused on the transformation of material, including Stone Age, Bronze Age, and Iron Age. The second, often referred to as the Industrial Revolution and Second Industrial Revolution, was dedicated to the transformation of energy, including hydropower, steam engine, electric power, and combustion power. Finally, the most recent metaparadigm aims at transforming information. It started out with the proliferation of communication and data storage and has now entered the age of algorithms, which aims at creating automated processes to convert the existing information into actionable knowledge.Hilbert, M. (2020). Digital technology and social change: The digital transformation of society from a historical perspective. Dialogues in Clinical Neuroscience
Several papers on the relationship between technology and the economy were written by researchers at the International Institute for Applied Systems Analysis (IIASA). A concise version of Kondratiev cycles can be found in the work of Robert Ayres (1989) in which he gives a historical overview of the relationships of the most significant technologies.
Cesare Marchetti published on Kondretiev waves and on the diffusion of innovations.
Arnulf Grübler's book (1990) gives a detailed account of the diffusion of infrastructures including canals, railroads, highways and airlines, with findings that the principal infrastructures have midpoints spaced in time corresponding to 55-year K wavelengths, with railroads and highways taking almost a century to complete. Grübler devotes a chapter to the long economic wave. In 1996, Giancarlo Pallavicini published the ratio between the long Kondratiev wave and information technology and communication.Giancarlo Pallavicini "La teorizzazione dei cicli lunghi dell'economia, secondo Kondratiev, e l'informatica e la comunicazione", Agrigento, 1996, Accademia Studi Mediterranei, Agrigento, http://www.giancarlopallavicini.it/cultura/accademia-studi-mediterranei
Andrey Korotayev et al. recently employed Frequency domain and claimed that it confirmed the presence of Kondratiev waves in the world GDP dynamics at an acceptable level of statistical significance.Spectral analysis is a mathematical technique that is used in such fields as electrical engineering for analyzing electrical circuits and radio waves to deconstruct a complex signal to determine the main frequencies and their relative contribution. Signal analysis is usually done with equipment. Data analysis is done with special computer software. Korotayev et al. also detected shorter business cycles, dating the Kuznets to about 17 years and calling it the third harmonic of the Kondratiev, meaning that there are three Kuznets cycles per Kondratiev.
Leo A. Nefiodow shows that the fifth Kondratieff ended with the global economic crisis of 2000–2003 while the new, sixth Kondratieff started simultaneously. According to Leo A. Nefiodow, the carrier of this new long cycle will be health in a holistic sense—including its physical, psychological, mental, social, ecological and spiritual aspects; the basic innovations of the sixth Kondratieff are "psychosocial health" and "biotechnology".See: Nefiodow, Leo; Nefiodow, Simone (2014): The Sixth Kondratieff. A New Long Wave in the Global Economy. Charleston 2014, .
More recently, the physicist and systems scientist Tessaleno Devezas advanced a causal model for the long wave phenomenon based on a generation-learning model and a nonlinear dynamic behaviour of information systems. In both works, a complete theory is presented containing not only the explanation for the existence of K-Waves, but also and for the first time an explanation for the timing of a K-Wave (≈60 years = two generations).
A specific modification of the theory of Kondratieff cycles was developed by Daniel Šmihula. Šmihula identified six long-waves within modern society and the capitalist economy, each of which was initiated by a specific technological revolution:
Unlike Kondratieff and Schumpeter, Šmihula believed that each new cycle is shorter than its predecessor. His main stress is put on technological progress and new technologies as decisive factors of any long-time economic development. Each of these waves has its innovation phase which is described as a technological revolution and an application phase in which the number of revolutionary innovations falls and attention focuses on exploiting and extending existing innovations. As soon as an innovation or a series of innovations becomes available, it becomes more efficient to invest in its adoption, extension and use than in creating new innovations. Each wave of technological innovations can be characterized by the area in which the most revolutionary changes took place ("leading sectors").
Every wave of innovations lasts approximately until the profits from the new innovation or sector fall to the level of other, older, more traditional sectors. It is a situation when the new technology, which originally increased a capacity to utilize new sources from nature, reached its limits and it is not possible to overcome this limit without an application of another new technology.
At the end of an application phase of any wave there is typically an economic crisis and economic stagnation. The 2008 financial crisis is a result of the coming end of the "wave of the Information and telecommunications technological revolution". Some authors have started to predict what the sixth wave might be, such as James Bradfield Moody and Bianca Nogrady who forecast that it will be driven by resource efficiency and clean technology. On the other hand, Šmihula himself considers the waves of technological during the modern age (after 1600 AD) only as a part of a much longer "chain" of technological revolutions going back to the pre-modern era. It means he believes that we can find long (analogical to Kondratiev cycles in modern economy) dependent on technological revolutions even in the Middle Ages and the Ancient era.
Health economist and biostatistician Andreas J. W. Goldschmidt searched for patterns and proposed that there is a phase shift and overlap of the so-called Kondratiev cycles of IT and health (shown in the figure). He argued that historical growth phases in combination with key technologies do not necessarily imply the existence of regular cycles in general. Goldschmidt is of the opinion that different fundamental innovations and their economic stimuli do not exclude each other as they mostly vary in length and their benefit is not applicable to all participants in a market.
