The generational interpretation of the post-depression era
The generational model holds that the K-cycle has shifted from one-half
to a full saeculum in length as a result of industrialization and is now about
72 years long. The cause of this lengthening is the emergence of government
economic management, which itself is a direct effect of industrialization as
mediated through the generational saeculum cycle. The rise of the industrial
economy did more than simply introduce the Kitchen cycle. It also increased
the intensity of the generationally-related Kuznets, Stock, and Kondratiev
cycles, all of which had already been part of the pre-industrial economy.
Thus, while the Kuznets-related Panic of 1819 was the first panic to make
it into the history books, it was a pretty mild bear market. The Panic of 1837
was worse and the one in 1857 worse yet. The Panic of 1873 ushered in the second
worst bear market of all time. The depression following the Panic of 1893 was
the worst up to that time. This depression was the first to take place with
a majority of the population involved in non-agricultural occupations. Although
hard times on the farm were a frequent occurrence, depressions did not usually
mean hunger. Yet for the large numbers of urban workers thrown onto "the industrial
scrap heap" the depression of the 1890's produced a level of suffering unprecedented
for a business fluctuation.
Despite the severity of the depression, little government action was taken.
President Cleveland resisted pressure to provide relief with expanded public
works programs, as did many in Congress. Senator James Berry of Arkansas, voicing
the dominant mind-set, declared that "It
is not the purpose of this government to give work to individuals throughout
the United States by appropriating money which belongs to other people and
does not belong to the Senate." Power was still held by the Gilded generation
(born 1822-42), the last to come of age in a pre-industrial America. This generation
was still steeped in the Jeffersonian concept of America as a nation of sturdy
yeoman individualists, who reject the sort of collectivist politics then popular
in Europe.
Yet the very next panic in 1907, although considerably milder in its effects,
brought reform in the guise of the Federal Reserve System. The Progressive
generation (born 1843-59) then in power had come of age in the midst of industrialization,
and was more cognizant of the new realities of industrial America. The Progressive
reforms occurred during one of the recurrent periods of political liberalism,
and were followed by a speculative conservative era. As it turned out, they
were not enough to prevent another panic and depression in 1929-33, this one
by far the worst of them all. This panic triggered the Crisis era
of the Strauss and Howe saeculum, (and another liberal era)
the first time a business cycle downturn had done so. Crisis eras produce massive
changes in society, and this one was no different. The generation in power,
the Missionary (b 1860-82), was the first completely industrial generation.
The response they crafted to the problems of the Depression (Keynesian economics)
and the dictators it produced (expansion in size of government) completely
transformed the role of government in the economy, diminishing the Kuznets
real estate cycle and producing a lengthened Kondratiev cycle now fully aligned
with the generational saeculum cycle.
The effectiveness of the crisis solutions reached its apogee during the period
after crisis, called the High,
which ran from 1946 to 1964. The High was a conservative era,
yet the liberal policies (e.g. high tax rates) introduced in the Crisis were
retained. These served to dampen speculative juices. As a result the post war
High was free of anything resembling a panic and the Kuznets cycle was muted.
Business cycles continued to be aligned with periodic bear markets as they
had been before 1933, except the period between them had increased to four
years, in accordance with the SMECT model. According to the generational model,
the fiscally conservative policies and financial self restraint of the 1950's
is a natural consequence of the generational peer-personalities of the adult
generations: cautious, risk-adverse Nomads in
elderhood, team-playing, disciplined Heroes in
mid-life, and compliant Artists in
rising adulthood.
By the late 1960's "self-expression" and the rise of the individualistic ethic
(coming with the arrival of a new generation of Prophets)
encouraged deficit spending, tax revolts and speculation. Strauss and Howe
call such periods Awakenings.
They are times when "people stop believing that social progress requires social
discipline" and develop "a high tolerance for risk-prone lifestyles". People
disdain the prosperity and security of a High, though covertly they are taken
for granted. The development of the Awakening mirrored a political shift from
conservative to liberal as well as an erosion in financial rectitude. Taxes
were cut in the early 1960's and the decision to finance the Vietnam war through
deficit-spending rather than increased taxes contributed to an inflationary
environment that would make speculation more attractive in the 1970's. War
stimulus was probably responsible for extension the 1960's expansion beyond
1966, when it should have ended according to SMECT.
Kondratiev spring ended in 1966, just two years after the beginning of the
Awakening, as indicated by the beginning of a secular bear market. Yet economic
good times continued until 1973. The credit crunch in 1966 failed to bring
on a recession; economic conditions remained favorable for the first half of
Kondratiev summer. On the other hand, the 1966 bear market signaled a shift
to a highly speculative era seeing first the "go-go years" of the late 1960's
and the "nifty-fifty" era of the early 1970's. This same period saw the re-emergence
of a full-blown Kuznets cycle. The persistence of good times over the 1966-1973
period reflected the efforts of government policy makers to maintain full employment
using Keynesian stimulus in the face of Kondratiev summer. It worked for a
while, but the inevitable result was stagflation. The experience of stagflation
did not lead to an abandonment of government economic management, but rather
to a change in style, from liberal Keynesian fiscal methods to conservative
supply-side monetary methods. This shift mirrored a political shift from
liberal to conservative. This shift was called the Reagan revolution, but another
interpretation of this era is what Strauss and Howe call an Unraveling.
The Unraveling "begins as a society-wide embrace of the liberating cultural
forces set loose by the Awakening". People "vigorously assert an ethos of pragmatism,
self-reliance, laissez faire, and national (or sectional or ethnic) chauvinism".
In the early 1980's, the Federal Reserve, under its new monetarist focus,
hiked interest rates to their highest level in the history of the United State,
breaking the back of inflation. Taxes were cut substantially again, especially
those for capital gains, and as inflation subsided, a great bull market in
stocks ensued. This policy had the same effect as that during the early 1920's
when the decline of WW I inflation, a capital gains tax cut, and a belief that
the Fed had made financial panics a thing of the past unleashed speculative
forces. The 1920-29 boom is cycle-equivalent to the 1982-2000 boom. The speculative
spirit reborn in the Awakening became sanctioned by official policy during
the Unraveling. For example, the 1987 stock market crash was met by copious
liquidity, which allowed the market to recover its losses in just two years,
resulting in extension of the already-long 1980's expansion to the next Kitchen
cycle. In 1997, Congress passed a capital gains tax cut in order to stimulate
further stock price rises in an already overvalued market, and the Fed executed
a well-timed surprise rate cut in 1998, which ignited an explosive stock rise,
even more extreme than the late 1920's blow-off. Both of these policies served
to extend the already long 1990's business cycle to three Kitchens, and as
a result Kondratiev fall was extended well beyond its length in previous cycles.
The net result of these various interventions has been to subtly increase the
length of the K-cycle from the 64-year length called for by SMECT to a 72 year
length fully aligned with the saeculum.
Discussion
SMECT does a good job of explaining and correlating the cycles over
the 1896-1982 period, but it breaks down for the most recent Kuznets cycle
from 1982 to 1998. The 1998 event (cycle-equivalent to
1932 in the SMECT scheme) was very mild--no recession and a bear market milder
than any other over this period. In particular, the present bear market, which
reflects simply a Kitchen cycle, should be milder than what was seen in 1998--but
clearly this is not the case. An argument can be made that policymaker intervention
has shifted the effects of Kondratiev winter forward from 1998 (when they should
have occurred) to now. No such intervention occurred for the last cycle and
so the 1929-1932 equivalent decline is playing out one Kitchen cycle later
than it normally would in the absence of policymaker interventions. This argument
is a "cycle lengthening" argument, but SMECT already accounts for cycle lengthening
though the mechanism of Kitchen cycle expansion. Further delays by policymakers should
already be part of any model for the post-1933 economy, when such interventions
are now normal. Thus, SMECT's failure to account for the extension of the boom
beyond 1998 is a problem.
Another feature of the SMECT model not yet discussed is that the lower order
cycles are necessarily in phase with
the longer cycles. That is, a BAAC Supercycle turning point (like 1998) is
necessarily also a turning point in all the lower-order cycles (Kuznets, Juglar
and Kitchen). The empirically-derived cycles shown in Table
6 do not support this alignment. Of course, the SMECT cycles do not refer
to the economic phenomenon associated with the cycles of the same name, they
are simply names used to classify cycles composed of geometric multiples of
Kitchen cycles--which do have a mechanistic interpretation in SMECT (they follow
the four-year electoral cycle). On the other hand, the higher order cycles
do have meaning. Sixteen Kitchens are supposed to define a K-cycle, which can
be independently assessed by long-term trends in monetary variables like interest
rates Eight Kitchens are supposed to define a BAAC supercycle and four a secular
stock market trend, both of which can be independently assessed using measures
like Tobin's Q. The only cycle in SMECT which does not have a specific independent
meaning is the Juglar cycle. The Juglar in SMECT does not correspond
with the longer category of business cycles since 1933 (see Table
6). The Juglar troughs in 1998, 1966 and 1942 fall into the middle of the
1990's, 1960's and WW II business cycles rather than align with their troughs
(see figure).
As an alternative to SMECT, I present the generational scheme shown in Table
8. The same four-year Kitchen cycles found in SMECT are retained. However no
fixed connection between these cycles and the longer ones is assumed. Although
each longer cycle will necessarily contain a whole number of Kitchen cycles
this number is not necessarily constant. The organizing principle behind these
cycles is Strauss and Howe's generational cycle, or more specifically the political
manifestation of these cycles. What seems to have happened initially after
1933 was expansion of K-cycle length to ~64 years according to the Kitchen
cycle expansion concept from the SMECT model. The mechanism for this expansion
was a rising impact of politics on economics. That is, economic cycles began
to map onto political cycles. The most obvious political cycle is the four
year electoral cycle, and so the four year cycle in the stock market appeared
almost immediately.

More subtle was the effect of the generationally-influenced liberal-conservative cycle (also
known as the Schlesinger cycle) which influenced the nature of government economic
management. During the conservative era of the 1950's the emphasis was on the
tenets of fiscal conservatism, balanced budgets and financial probity, even
at the cost of maintaining the high tax rates from WW II. Although conservative
politics tends to favor wealth creation, the style of management during
the High was not conducive to speculation, reflecting the generational dynamics
of the High. The secular bull market from 1949-1966 ended at the lowest valuation
level of any secular bull market, showing the depressed "animal spirits" of
the time. As the High gave way to the Awakening, things "loosened up" financially,
taxes were reduced and not raised when the nation went to war, and speculative
forces began to stir. By the time of the next conservative, pro-wealth creation
era in the 1980's, a free-wheeling, pro-speculation style of economic management
was in vogue, reflecting the generational dynamics of the Unraveling. The secular
bull market peak associated with this era had the highest valuation
level in history, showing extremely powerful animal spirits--exactly the reverse
of the previous secular bull market peak.
The timing of this process is set by generational dynamics--as mediated through
politics on the economy, and not by economic forces themselves. Hence the fundamental
large-scale economic cycle, the Kondratiev, and its subharmonics, the Stock
Cycle and K-season, adapted to reflect the length of the saeculum, which itself
changed to reflect a psychological driver for the cycle. (The classical K-cycle
and saeculum had been related to biological generations.). The key timing
element of the longer cycles today is the 18 year psychological generation
and the 18-year political trends associated with them. This timing determines
the length of the secular market trends and the modern business cycle, whereas
the short stock market cycles reflect the electoral cycle. Standing aside is
the Kuznets cycle, which appears to have retained its traditional 18 year length.
The Kuznets cycle is not aligned with the K-cycle. Although of the
same average length, it is not the same as the Kondratiev season as
it is in SMECT (see Table 6). The two cycles are not
in phase. Thus, although Kondratiev season changes can exert a strong effect
on downturn severity, so can the unaligned Kuznets cycle. Hence, the present
recession, although "K-cycle equivalent" to 1932, is not as severe as even
the mild 1990 recession because it lacks a real-estate (Kuznets) cycle downturn.
One might point out that current strength in real estate reflects the 11 rate
cuts made by the Federal Reserve since the beginning of 2001. But these 11
rate cuts have done nothing to prevent the stock market from falling 35% since
then. The stock market fell because it had gotten too overvalued, that is,
it had reached its peak in the Stock Cycle and thus had to start coming down,
regardless of the what the Fed did. On the other hand, real estate valuation
has not reached extreme levels as shown by the ratios of price to income in Figure
5. That is, the Kuznets peak has yet to be reached. Thus, rate cuts have
supported real estate, just as they did for stocks in 1998. By 2004 we may
well have reached a Kuznets peak and then one would expect rate cuts by the
Fed to be ineffective in preventing a real estate bust in the next recession.
This interpretation suggests that the current downturn is largely stock market
driven, being the result of the inevitable downturn following a peak in long-term
stock market valuation (P/R). Indeed, current weakness almost entirely comes
from weak business investment spending, reflecting the poor business outlook
generated by continuing weakness in the stock market. Consumer demand has remained
strong.
Thus, if the cycle scheme suggested here is correct, no double-dip recession
is to be expected and the stock market may well rally over the next few years,
in accordance with P/R valuation.

Appendix A: Defining Bear Markets
Bear markets are usually considered "large" declines in the stock index over
a fairly lengthy period of time. A common rule of thumb is any decline of 20%
or greater. The market analyst Robert Bronson has
developed novel measure of bear market severity which I will make use of here.
This method accounts for both the magnitude and the length of the bear market
decline and is defined as follows:
A.1 Severity = log(index top/index bottom) x duration in months
For example, the current bear market, which began at the S&P500 intra-day
peak of 1552.87 on March 24, 2000 has reached (so far) an intra-day low of
768.63 on October 10, 2002. Through the October low, the bear market has lasted
30.5 months. From this data I can calculate a severity as follows:
A.2 Severity = log(1552.87/768.63) x 30.5 = 9.3.
Bronson has listed thirty bear markets
since 1895 as assessed by this criterion. Already the present bear market falls
into the #2 position in his list, and it may not yet be over. The nature of
this measure can make fairly small declines significant bear markets--if they
last long enough. For example, the short, but severe 1987 bear market showed
a decline 150% greater than the much longer 1960 bear market yet was 40% less
severe by the Bronson criterion. This makes identification of major bear markets
more difficult than the use of the simple 20% rule. Some of the bear markets
in Bronson's list seem pretty small. For example the 1926 bear market has a
severity of only 0.12. One can find declines not on his list with greater severity.
For example, the 12% Dow decline from July 15, 1943 to November 30, 1943 (severity
= 0.25); the 10.8% S&P500 decline from Sept 25, 1967 to March 5, 1968 (severity
= 0.26); or the 13.9% S&P500 decline from April 29, 1971 to November 24,
1971 (severity = 0.45).
None of these declines fits the 20% standard, but they all are more severe
(by the Bronson definition) than the 1926 bear market, yet are not included
in the list of top bear markets. If we focus more closely on the 1926 bear
market, we see that it was associated with an NBER recession dated from October
1926 to November 1927. It is reasonable to assign special significance to a
market decline that is associated with an economic decline. None of the declines
mentioned above were associated with recessions. If we look only at non-recession
bear markets that did not show 20% declines, we see that only one of Bronson's
bear markets (1994) is of similar magnitude to those mentioned above.
Figure A.1, which shows a plot of index value relative to ten-year trend[1],
has 1994 displayed as a prominent low, reflecting the sea change in stock returns
that occurred at this point. None of the declines mentioned above feature prominently
in Figure A.1. If we exclude 1994 on the basis of this significance, the rest
of the bear markets have severity greater than 0.5 or show a 20% decline. From
these observations the following "rule" for bear markets was developed:
"A bear market is any decline of 20% or greater, or a severity of 0.5 or greater.
Declines smaller than 20% and with severity between 0.1 and 0.5 are also considered
bear markets if they occurred at the same time or just before an NBER recession,
or form a major low on a plot of stock index versus 10-year trend."
Figure A.1 Stock index versus its ten year trend, showing
major bear market bottoms

All of the bear markets listed by Bronson fall into these criteria. None
of those I listed earlier do, and thus should not be included in the list.
There is one more issue with which I need to deal before a complete methodology
for defining bear markets has been defined. One of Bronson's declines, the
1929 bear market, is part of a larger decline from 1929 to 1932--yet it is
considered a separate bear market. Apparently, it seems the rally from Dow
195.4 on 11/13/29 to 297.3 on 4/16/30 was "big enough" to be considered a separate
bull market. I can calculate a "severity" for this bull market as follows:
A.3 Bull market size = log (297.3/195.4) x 5.0 months = 0.91
A rally with severity of 0.9 or better, it would seem, constitutes a bull
market. In comparison, I note the recent rally from S&P500 944.75 on September
21, 2001 to 1176.97 on January 7, 2002 scores an intensity of only 0.34:
A.4 Bull market size = log (1176.97/944.75) x 3.6 months = 0.34
This is much smaller than the 1929-30 rally and is consistent with the general
sense that the 2001-2002 rally was "just" another bear market rally and not
a bull market.
The market nearly reached the January top on March 11. If I use this later
date for the end of the rally I obtain a severity of 0.53, still well below
the size of the 1929-30 rally. Nothing is changed. However, suppose the market
had reached a peak of 1373 or higher on March 11, instead of forming a double
top? In this case, the rally would have been as large as the 1929-1930 rise.
Would such a large rally have been considered a bull market? It is impossible
to know, but it seems reasonable to me that the vast majority of market participants
would have hailed a rise of this magnitude (before it peaked) as a new bull
market.
After this discussion one can add the definition of intervening bull market
as a rise in a larger decline that is 0.9 or larger. With this, our rules for
locating bear markets are complete.
[1] The ten year trend is obtained by regression of log(index)
versus time over the ten year period centered on the point of interest. Thus
the trend for a point in 1990 is regression of data over 1985 to 1995. For
points after 1997 or before 1807, the regression equation for the 1992-2002
and 1802-1812 period is used.
Appendix B. Identifying Business Cycles
The National Bureau of Economic Research (NBER)
has identified US business cycles back to 1854. Prior to that one can use the
GDP relative to its trend as a crude estimate for cycles. I already used this
approach with a ten year trend to help identify stock bear markets in Figure
A.1. This time I use a 25 year trend which is shown in Figure B.1 for data
between 1790 and 1890. Also shown in the figure as the thick light-gray line
is the Kondratiev seasonal cycle. This cycle is a binary subharmonic of the
Kondratiev cycle (two seasonal cycles per K-cycle) and is correlated with the stock
cycle. It is the same cycle that Bronson calls the BAAC Supercycle.
I used a plot analogous to Figure B.1, but using a 100 year trend, to show
this cycle in my book The Kondratiev Cycle (p
67).
Figure B.1 GDP relative to 25-yr trend showing K-seasonal and ordinary business
cycles

Within the larger season cycles, there are smaller perturbations, which presumably
reflect ordinary business cycles. In The Kondratiev Cycle I smoothed
these to de-emphasize them and bring out the longer cycle. Now I wish to examine
these shorter cycles. Recession troughs are marked by visual inspection. Four
troughs (marked in red italics) are the
recessions associated with the four big "panics" that occurred during the period
shown in the chart: the panics of 1819, 1837, 1857 and 1873. The others are
either "major" troughs or isolated ones. Figure B.2 shows more cycles for the
period 1880-1950.
Figure B.2. K-seasonal and ordinary business cycles 1880-1950

To test the validity of these troughs I compare them with those obtained by
NBER. Table B.1 shows troughs from Figures B.1 and B.2 compared to the NBER
recession bottoms. The correspondence is quite good. All but three NBER recessions
have a corresponding trough and only one trough doesn't have an associated
NBER recession. This suggests that the business cycles obtained from Figure
B.1 can be used to provide estimates for business cycle dates before 1854.
