PART III: MANIC-DEPRESSIVE SOCIAL PSYCHOLOGY

Thus far, a substantial body of empirical evidence has been presented which strongly suggests the behavior of markets and society in general is literally insane. Specifically, man as a species currently appears to be suffering from collective emotional and mental instability that is manic-depressive in character. Wave patterns in stock prices, business cycles like Kondratieff's long-wave and contrarian phenomena exist because the collective mood of investors and social participants swings between irrational extremes of optimism and pessimism.

-The Initial Discovery-

In 1992, I proposed the idea of "manic-depressive man" in a letter written to Elliott Wave theorist Robert Prechter:

I have just tapped upon a new theory which I'm sure will interest you very much. I've discovered something which seems to tie together wave theory, mood swings, and the dynamics of social change in an extraordinary way. As a whole, man may very well be insane at present- grossly out of touch with reality. specifically, the mass psychology of humanity (or at least Western Civilization) may be at the end of an unprecedented episode of creative mania and is about to sink into a severe depression which could ultimately lead to self- destruction.

As is readily reflected in the market, the mood of man naturally swings from optimism to pessimism. What's important to note, however, is that in recent centuries the mood swings have grown increasingly pronounced and regular. This has coincided with a major upsurge in human creativity. The implication of this pattern is that man may currently be suffering from a 'mad-genius' syndrome- what psychologists refer to as 'manic-depressive illness'.

In order to properly diagnose man as manic-depressive, let's first examine exactly what the disorder entails.

-Manic-Depressive Syndrome-

Manic-depressive syndrome involves distinct, periodic mood swings between excessive optimism (mania) and excessive pessimism (depression).
According to the diagnostic criteria of DSM-III-R (the manual used by clinicians to make psychiatric diagnoses), episodes of mania typically involve the following symptoms (1):

1. A distinct period of elevated feelings and over-optimism.
2. Inflated self-esteem.
3. Increased activity and a decreased need for sleep.
4. Racing thoughts, flight of ideas, and an overactive imagination.
5. Increased goal-oriented activity, esp. work.
6. Buying sprees and reckless over-consumption.
7. Risky speculation and investment activity.

In general, mania entails a sharp, positive upsurge in thoughts, feelings, and physiological activity. If this energy is properly focused, then heightened productivity and creativity results. The energetic feelings and active imagination of a manic makes supernormal accomplishments possible, although this may coincide with potentially harmful over-indulgence and speculation as well as grandiose delusions.

According to the diagnostic criteria of DSM-III-R, depression involve the opposite features of mania: depressed mood, low self-esteem, fatigue and listlessness, slowed thought and poverty of ideas, apathy, and sharply reduced consumption and investment activity. During depression, a person may experience panics- boughts of overwhelming irrational fear and guilt. In general, they become morbid and destructive in both thought and behavior (2).

-Seasonality-

One of the distinctive features of manic-depression is the periodicity of mood swings. The recurrent cycles between positive and negative affect in a typical manic-depressive follows a circannu_al rhythm. In other words, there is a dominant annual seasonal pattern to manic-depressive mood swings. This seasonality is depicted in the following diagram:
Figure 1

As can be seen, mania tends to hit during the summer months; swings into major depression occur during the fall and spring- particularly September/October and April/May; winter seems to be characterized by an extended mild depression (3).

The actual seasonal variation in the mood swings of manic-depressive patients is shown in the histogram below:

Figure 2

There are distinct spikes at the 6 and 12 month intervals and any interval that is a multiple of 12 months thus showing the dominant circannual pattern to manic-depressive cycles (4). Further evidence of the seasonality of manic-depression comes from historical suicide rates. The potential for major depression in the April/May and September/October periods is reflected by seasonal peaks in suicide occurrences in the months of May and October (5). with regard to circannual mood swings, this means that during the peak seasonal transition periods there is the highest emotional disturbance and greatest potential for major depression and suicide attempts.

Notably, the seasonality of mood swings is not strictly a phenomenon among manic-depressive personalities. A circannual oscillation in mood is evident across the general population, just to a lesser degree:

Seasonal variations in mood and behavior appear to be common - in the general population as well as in individuals with affective disorders. Eastwood and colleagues (1985) compared the infradian rhythms of mood, sleep, anxiety, and energy over a period of 14 months in 30 patients with affective illness and 34 healthy control subjects matched for age and sex. They found that the majority of patients and many of the healthy subjects had infradian rhythms in mood, energy, and sleep, and about half of these were seasonal (6).

-Manic-Depression & Creative Genius-

"I am come of a race noted for vigor of fancy and ardor of passion. Men have called me mad; but the question is not yet settled, whether madness is or is not the loftiest intelligence- whether much that is glorious- whether all that is profound- does not spring from disease of thought- from moods of mind exalted at the expense of the general intellect."
(Edgar Allan Poe)

Psychologists and psychiatrists have recognized that manic- depression often is a "Key to Genius" (7). The mental and emotional instability of manic-depressive personalities goes along with extraordinary imagination and innovative thinking. Thus, as paradoxical as it may seem, something psychologists have classified as a psychotic mental "disorder" is, in fact, qften a part of supernormal mental capabilities.

The reality is that manic-depression has been a factor in the lives of many of the creative personalities that have shaped human science, culture, and history. Some of the more renown individuals to have shown classic manic-depressive traits were: musical composers such as Mozart, Beethoven, Tchaikovsky, Handel, Schumann, and Wagner; the majority of renown writers and poets- e.g., Yeats, Shelley, Lord Byron, Emerson, Dostoyevski, Tolstoy, Goethe, Poe, Dickens, Melville, Hemingway, J.S. Mill, F. Scott Fitzgerald, Virginia Woolf, etc.; great philosophical and scientific minds like Plato, Aristotle, Socrates, Descarte, Rousseau, Nietzsche, Bacon, and Newton; key political leaders like Napoleon, Lincoln, Lenin, Hitler, Mussolini, and Churchill; and influential religious leaders such as Luther, Calvin, and William James (8). Ironically, therefore, some of the greatest minds in history were, in fact, severely unstable. This is most strongly reflected by the fact that, at the same time such geniuses as Beethoven, Dickens, Rousseau, and Newton were thinking up their creative masterpieces, they were concomitantly suffering from irrational and typically grandiose hallucinations and/or delusions.

To get a sense of just how common manic-depression is among creative personalities, consider the following chart and histogram which show the prevalance of severe mood disorders among British writers and poets:

To give you an idea of how manic-depression typically influences the productivity of a creative genius, consider the chart below of Robert Schumann's life work:

Figure 5


As can be seen, episodic manias and depressions throughout Schumann's adult life shaped the pattern of his work. When manic, he composed an enormous amount of music, but when depressed Schumann achieved little or nothing. The tragedy of his manic-depressive personality is demonstrated by how the life of this musical genius was dotted with suicide attempts and by how, at the relatively young age of 46, Schumann died of self-starvation in an insane asylum.

Summarily, manic-depression often corresponds with creative genius. Some of the greatest minds in history were what modern psychiatry refers to as "disordered". Manic-depressive personalites pervade the creative arts and sciences and often become important leaders because their mental and emotional instability goes along with a supernormal flow of innovative thoughts and actions. More specifically, periods of mania allow for extraordinary creativity and productivity after which a period of reduced activity and depression occurs. Eventually the depression
lifts, however, opening the way for another creative upswing.

-The Diagnosis of Manic-Depressive Man-

In diagnosing society as manic-depressive, one needs to consider the combined implications of Elliott Waves, business cycles, Kondratieff Waves, and contrarianism. These empirical phenomenon are the evidence, the sociological symptoms, that warrant a diagnosis of manic-depressive man.

-Elliott Waves and Contrarianism-

As Prechter has pointed out, Elliott Waves reflect that "mass investor psychology swings from pessimism to optimism and back in a natural sequence". In other words, Elliott Waves are, by definition, a phenomenon of bipolar swings in popular mood- swings between the two poles of positive and negative affect.

That Elliott Waves in market prices are a symptom of popular manic- depressive mood swings is corroborated by contrarianism. A contrarian investment strategy works only because of the manic-depressive character of market psychology. The underlying cause of cycles in market prices is swings in the aggregate mood of investors. Because of radical subjectivity, greed and blind speculation, the consensus beliefs and expectations of investors swings between irrational extremes of optimism and pessimism. The prices of individual stocks or entire markets are speculated to unrealistic heights by mass greed and then pushed to unrealistic lows by mass fear. By paying attention to indicators of market psychology and investor expectations such as opinion polls, cash levels, valuation measures, and stock offerings, astute investors can determine when extremes of optimism and pessimism are being reached and thereby successfully determine in a contrarian fashion when to buy and sell as well as what to buy and sell. Thus, by going against the irrationality of the crowd, a contrarian successfully times the tops and bottoms of cycles in market prices caused by manic-depressive crowd psychology. As is reflected by the varying scale Elliott Waves that can occ~r- periodicities ranging from days to centuries- popular manic-depressive mood swings come in many shapes and sizes. One way in which varying scale mood swings manifest beyond market prices is business cycles. The 3- to 5-year Kitchin cycle, the 7- to ii-year Juglar cycle, the 15- to 25-year Kuznets cycle, and the 50- to 60-year Kondratieff long-wave, are the known business cycles (10). Each of them represents a different scale bipolar swing in social mood.

-Psychological Theories of the Business Cycle-

The "psychological theories" of business cycles that have been developed up until now by economists such as J.M. Keynes, A.C. Pigou, and F. Lavington, are consistent with the theme of this paper. In his book Prosperity and Depression, economist Gottfried Haberler points out that psychological theories emphasize the impact of "optimism", "pessimism", and subjective "irrational influences" (Keynesian "animal spirits") on market and economic behavior (11):

The theorists of who stress the psychological factor, especially Professor Pigou and Hr. Keynes, point out, furthermore, that the discovery of errors of optimism aives birth to the opposite error of pessimism. Professor Piaou spea~sof 'the mutual aeneration of errors of optimism and pessimism'. The above passage from Hr. Keynes continues: 'When disillusionment comes, this (optimistic) expectation is replaced by a contrary error of pessimism, with the result that the investments which would in fact yield 2% in conditions of full employment are expected to yield less than nothing; and the resulting collapse of new investment then leads to a state of unemployment in which the investment, which would have yielded 2% in conditions of full employment, in fact yields less than nothing. '

Professor Pigou points out that 'the extent of the revulsion towards pessimistic error, which follows when optimistic error is disclosed, depends, in part, upon the maanitude of the precedina optimistic error... .But it is also affected by what one may call the detonation which accompanies the discovery of a given amount of optimistic error. The detonation is greater or less according to the number and scale of the legal bankruptcies into which the detected error explodes.' If the enterprises which are making losses have been financed by the entrepreneurs with their own money, the repercussions are less serious than in the case where they have been financed by borrowing, especially borrowing from the banks. (12)

The symmetries between "psychological" theories of the business cycle and contrarianism should be clear. The "contagion of confidence" emphasized by Lavington is the groupthink of investor sentiment emphasized by David Dreman. The way in which that confidence leads to "excessive valuation of capital assets" is no different than how mass speculation leads to relatively overvaluated financial assets like high PIE stocks. The "discovery of errors of optimism", "dissillusionment", and "contrary error of pessimism", is the turning point in popular sentiment, consensus opinion, and market prices that contrarianism is used to determine. Thus, the behavior of markets as described in
.
Prechter's Elliott Wave theory and Dreman's contrarianism parallels the behavior of the economy as described by "psychological theorists" such as Lavington, Pigou, and Keynes.

-Kondratieff's Long-Wave and Severe Social Mood Swings-

While Elliott Waves, business cycles, and contrarianism are strongly indicative of manic-depressive man, no where is the symptoms of an actual social disorder more evident than in the long-waves discovered by Nikolai Kondratieff. The Kondratieff wave clearly depicts recurrent, large-scale swings in society between creative prosperities and stagnant depressions. Furthermore, the different phases of the Kondratieff wave includes periodic episodes of dangerous, psychotic mania that are followed by panic and crashes into major social depressions. (13)

The general upswing of the Kondratieff wave is characterized by continuous productivity gains, economic growth, expanding demand, and rising prices, mood, and expectations. In American economic history, this occurred during the periods: 1789-1814, 1843-1864, 1896-1920, and
1937-1970's (see part I for graph). Each of these general upswings peaked with a spike in general prices caused by excessive expectations with regard to future demand and economic growth.

The spike in general prices is broken by a sharp, unexpected slump in the economy- the "primary recession". As general disinflation takes hold a distinct episode of "social mania" is set-off, i. e. , the so- called IIdisinflationary boom" or "speculative blow-off" stage of the Kondratieff wave. Transitions into full-blown manic-episodes struck the United States during the following periods: 1812-1814, 1863-1864', 1920- 1921, and 1979-1982.

The symptomology of a society caught up in a social mania is consistent with the DSM-III-R criteria used to diagnose individual manic-episodes (see above):

1. A distinct period of elevated feelings and over-optimism.
2. An inflated sense of group confidence.
3. A sharp increase in business and social activity.
4. A flurry of new ideas and innovations.
5. Increased goal-activity as reflected in higher productivity. -
6 Reckless over-consumption and heavy debt accumulation.
7. Rampant speculation and risky investment activity.

With regard to social manias, the final symptom listed above, speculation, appears to be particularly relevant. Indeed, the term "speculative mania" is often applied to Kondratieff disinflationary booms. The nature of these manias is described in such classic texts as Charles Kindleberger's Manias. Panics. and Crashes and Charles MacKay's Extraordinary Popular Delusions and the Madness of Crowds (14). Kindleberger offers an intriguing list of the words and phrases used in historical literature to describe speculative manias: "manias, insane land speculation, blind passion, financial orgies, frenzies, feverish speculation, epidemic desire to become rich quick, wishful thinking, intoxicated investors, turning a blind eye, people without ears to hear or eyes to see, investors living in a fool's paradise, easy credibility, overconfidence, overspeculation, overtrading, a raging appetite, a craze, a mad rush to expand". (15)

In association with Kondratieff disinflationary booms, America has suffered four episodes of social mania each of which involved rampant speculation and most of the other symptoms listed previously. Furthermore, they have become increasingly pronounced and severe over history. The first two episodes, the "Era of Good Feelings" that followed the War of 1812 and lasted until 1819 and the "Reconstruction" or "Industrial Overexpansion Prosperity" between the end of the Civil War and 1873, were relatively mild compared to the episodes of the twentieth century. The "Roaring Twenties" between 1921 and 1929 was a classic example of a social mania and involved all of the symptoms listed above. Furthermore, the Roaring Twenties involved a speculative mania the likes of which the world had not seen since the South Sea Bubble developed in early eighteenth century England. Overshadowing the Roaring Twenties, however, is the social mania that started in 1982 and is still underway to this day. As described, for example, in Adam smith's book called "The Roaring Eighties", America is experiencing one of the most severe Kondratieff wave manic episodes in its history.

Following the Kondratieff wave outline, social manias are followed by a major panic and collapse into a "secondary" social depression. The cross-population symptomology of social depression is, again, consistent with the DSM-III-R criteria for diagnosing major depression in individuals, i.e., depressed social mood, low group confidence, general listlessness and apathy, sharply reduced business and social activity, lack of new ideas and subdued innovation, and depressed consumption and investment activity. As with individual manic-depressives, society usually suffers panics during major depressions- i.e., boughts of overwhelming irration,al fear that are associated with severe financial crises.

As with its episodes of social mania, America's panics and depressionary collapses have become increasingly severe over history. The panic of 1818/1819 was relatively mild compared to the stock market crash and financial panic in September of 1873. Likewise, the slump in socioeconomic activity, popular sentiment, and prices between 1819 and 1843 did not earn the title of a "Great Depression" as did the slump between late-1873 and 1896. The panic of 1873 and subsequent depression were relegated to a footnote of history, however, by the "Great Crash" in October of 1929 and the Great Depression of the 1930's. The Great Depression involved all the symptoms of major depression listed above and involved multiple panics, particularly between 1929 and 1933.

In summary, Kondratieff's long-wave is one of the most severe bipolar mood swings suffered by society. The extended upswing and downswing of long-waves entail large-scale swings between creative prosperity and optimism and general stagnation and pessimism.

Furthermore, the speculative blow-off, panic, and secondary depression of the Kondratieff wave is equivalent to a distinct episode of social mania followed by a collapse into major depression. According to the manic-depressive interpretation of the Kondratieff wave, there have been around three and a half bipolar long-cycles in American history, each of increasing severity. In the context of the current cycle, society is at the tail end of its worst manic-episode. ever and a crash into an unprecedented depression is imminent.

-Seasonality-

Notably, the seasonality of manic-depressive mood swings in society is consistent with the seasonality of mood swings in bipolar individuals. Seasonal patterns in the mood of investors is reflected ~n stock price movements. Furthermore, their is a distinct seasonality to severe social panics and breaks into major depression.

Figure 7


As can be seen in the table above, the stock market typically swings in line with the circannual ryhthm of mood of manic-depressive individuals depicted in figure 1 at the beginning of this chapter. During the summer there is typically elevated sentiment and rising prices in what has come to be called the "summer rally". The spring and fall are the worst period for stock prices; historically, May, September, and October are the only months that stock prices are down on average. During the winter the market is generally up but not so much as during the summer. The typical pattern is for a significant rally from late December into January, i.e., the so-called "January effect" (16).

The seasonality of popular mood is best revealed by the timing _of major panics in American history. Consider, for instance, the following diagram from Eugene White's Crashes and Panics:

As can be seen, the worst social panics and stock crashes in American history typically occurred in the April/Mayor September/October periods- consistent with the pattern seen in individual manic- depressives. This seasonal tendency has been especially true during the twentieth century with crashes into October 1907, October 1929, OctoQer 1946, May 1962, October 1987, October 1989, and October 1990 (17). Notably, the severe panic and break into social depression every 50-60 years following a Kondratieff social mania has always struck around the September/October period: November 1818, September 1873, October 1929.

Interestingly, in America there is a unique cultural manifestation of October panic and depression. Given that the "Great" Crashes of 1929 and 1987 occurred on October 29th and October 19th, respectively, late- October appears to be the point of most acute seasonal transition and, in turn, mass fear. A cultural manifestation of this seasonal mood that is unique in America is "All Hallow's Eve" or, as it's more commonly referred to, Halloween. This dark holiday is about as explicit an expression as possible of a seasonal popular mood that is fearful, morbid, and depressed.

-The Creative Disorder of Man-

As was explained above, manic-depression often corresponds with creative genius in individuals. Many of the most creative personalities in history were manic-depressive. With regard to society, a s~me pattern appears to exist. The more pronounced the manic-depressive tendencies of popular mood, the greater the creativity.

The correlation between social manic-depression and creativity is most evident in America. The bipolar mood swings in American society are both distinct and, as reflected in recent Kondratieff long-waves, of increasingly severe magnitude. This pattern exists in what is probably the most creative society in the history of the world. What is more, the creativity of America has been particularly pronounced during the twentieth century- in conjunction with its most severe historical mood swings.

-Joseph Schumpeter, Business Cycles, & Innovation-

". ..the bulk of private fortunes is, in capitalist society,
directly or indirectly the result of the process of which
innovation is the 'prime mover'"
(Joseph Schumpeter, Business Cycles)

That cross-population manic-depression is associated with man's creative potential appears to be revealed in "innovation theories" of business cycles and the Kondratieff wave in particular (18). While Schmookler and Hensch have offered evidence and theoretical support to the idea that innovation lies behind cycles, especially the long-cycle, no author has carried out a more comprehensive treatment of the subject

than Joseph Schumpeter. In a nutshell, Schumpeter attempted to construct a "disequilibrium" model of the Capitalist system that demonstrated the role of innovation and endogenous change (19).

In economic theory, the Capitalist system is depicted in stati.c, equilibrium models in which change is caused only by external forces. Schumpeter thought of this as follows:

I felt very strongly that this was wrong, and that there was a source of energy within the economic system which could itself disrupt any equilibrium that might be attained. If this is so, then there must be a purely economic theory of economic change which does not merely rely on external forces propelling the economic system from one equilibrium to another. It is such a theory that I have tried to build and I believe now, as I believed then, that it contributes something to the understanding of the struggles and vicissitudes of the Capitalist world and explains a number of phenomenon, in particular the business cycle, more satisfactorily than it is possible to explain them by means of either Walrasian or the Marshallian apparatus. (20)
And what "source of energy within' the economic system" did Schumpeter conclude was responsible for disequilibrium and change? That ultimate force at the core of all historical development: creative thought.

In his Theory of Economic Development and again in his monumental work, Business Cycles: A Theoretical. Historical. and Statistical Analysis of the Capitalist Process, Schumpeter took multiple steps to build a realistic economic model of what is appropriately referred to as "general disequilibrium". After a first approximation in which only a two-phase business cycle is developed, Schumpeter models a second approximation that leads to a four-phase business cycle (21). This cycle consists of prosperity, recession, depression, and recovery and is graphically represented below:

To get the four-phase cycle above, Schumpeter begins with a "pure" model of the economy in which there is no change. Schumpeter's pure economy is characterized by a balanced circular flow of economic activity in which all knowhow and processes are routine. This system, which is effectively the neoclassical economic model, is characterized by general equilibrium and a lack of profits; all factor inputs receive payments equal to the value they add to output.

After building his pure, equilibrium model of the economy which, by definition, is a system in which there is no tendency for change, Schumpeter introduces entrepreneurship and innovation. In other words, he introduces change. Due to innovation, the balanced circular flow of the economy is disrupted and, consequently, profit opportunities emerge. In order to exploit these opportunities, financial investment, credit, and interest emerge. Productivity increases and there is economic growth. Financial boom, high expectations and prosperity are realized: a business cycle upswing has been triggered.

Eventually the impact of innovation runs its course and a growth recession occurs. What were once "new" ideas have become a routine part of the economy. As profits dwindle, investments fail to offer their expected return. The recession soon becomes a depression as bankruptcies occur, credit contracts, expectations turn negative, and investment activity drops-off.

Inevitably the downwave of "creative destruction" reaches a bottom and a recovery ensues. The economy eventually returns to f~ll production and equilibrium, but at a higher level of productivity than had been the case before innovation was introduced.

After using two approximations to establish the simple four-phase business cycle of prosperity, recession, depression, and recovery, Schumpeter develops a third and final approximation which results in the simultaneous occurence of three different four-phase business cycles in an economy. By introducing innovations in periodic clusters and with varying scale impact, Schumpeter shows that the capitalist system will be characterized by at least three business cycles of different length (22). Specifically, his model demonstrates how the 40-month Kitchin cycle, 9- to la-year Juglar cycle, and 50- to 60-year Kondratieff cycle occur simultaneously.

Importantly, while Schumpeter found the above scheme to be "useful" in his work, he did not consider it a comprehensive model of the business cycles that occur in the capitalist system. He understood that the number of cycles could be indefinite- a point Robert Prechter would be quick to second. (20)

After completing his dynamic, disequilibrium model of the economy, Schumpeter takes but one more radical step beyond neoclassical economics and actually provides exhaustive empirical support for his theory. (Obviously orthodox economists fail to do so for the most part because examining economic reality would falsify their "equilibrium" models.) In Business Cycles, Schumpeter devotes the first five chapters and 220 pages to building his economic model of general disequilibrium and then spends ten chapters and 830 pages corroborating his model with a "histor.ical and statistical analysis of the capitalist process".

Specifically, Schumpeter reviews American, British, and German economic history from the late-eighteenth century through the Great Depression of the 1930's in the context of the varying scale business cycles depicted in his model. In other words, he overviews the historical pattern of disequilibrium and change that is involved in the "capitalist process".

While Schumpeter believes that entrepreneurial activity is responsible for the smaller scale business cycles, what is most pertinent here is what role he thought innovation played in large-scale business cycles in the American economy, i.e., the Kondratieff wave. On this subject, Schumpeter wrote:

Historically, the first Kondratieff covered by our material means the industrial revolution.. ..We date it from the eighties of the eighteenth century to 1842. The second stretches over what has been called the age of stearn and steel. It ran its course between 1842 and 1897. And the third, the Kondratieff of electricity, chemistry, and motors, we date from 1898 on. (24)

Schumpeter's long-wave chronology is broken down in the table below:

Schumpeter's long-wave chronology
prosperity recession depression recovery
1. Industrial Revolution Kondratieff: cotton textile, iron, steam power - 1787-1800 | 1801-1813 |1814-1827 |1828-1842
2. Bourgeois Kondratieff: railroadization - 1843-1857 |1858-1869 | 1870-1884/5 | 1886-1897
3. Neo-Mercantllist Kondratieff: electricity, automobile 1898-1911 | 1912-1924/5 | 1925/6-1939

Figure 11

All in all, Schumpeter recognized that cycles of prosperity and depression are part of the process involving ongoing innovation and dynamic change called "capi talism" . He ties the three completed Kondratieff waves in American history to key innovations that changed the overall way of doing things within the economy. These radical transformations corresponded with radically changing knowhow and procedures throughout society which both required and fed into a highly dynamic and unstable mass psychology.
.
In summary, Schumpeter's theory of economic development can be reduced to four basic propositions (25):

1. Innovation is the fundamental impulse which sets and keeps the capitalist engine in motion.
2. Innovations are an essentially discontinuous phenomenon: they appear in swarms.
3. Therefore economic development is a cyclical process: 'cyclical "waves" are essentially the form "progress" takes in competi ti ve capitalism' .
4. Innovations have different impacts. That is why, simultaneously, cycles of different length exist. The long wave is caused by such basic innovations as railroadization, electrification and motorization.
