Factory Size, Economies of Scale, and
the Great Merger Wave of 1898-1902
ANTHONY
PATRICK O'BRIEN
Analysis of census data reveals that the size of the average factory in the United
States grew more rapidly during the 1870s and 1880s than during any subsequent
decade through the 1920s. While the average factory doubled in size between 1869
and 1889, it increased by only about a quarter between 1899 and 1929. These
results support the view that the reaping of economies of scale was not an
important motive for the great merger wave.
here are two views on the importanceof the mergerwave of 1898to
1902 in the evolution of the industrial structure of the American
economy. The first holds that duringthe 1870sand 1880sthe completion
of basic economic infrastructureand the appearance of important
technological and organizationalinnovations led to an increase in the
minimumoptimalscale of plants in many manufacturingindustries.The
result was the developmentof large firmsand an attendantoligopolistic
structure.The mergerwave, in this view, was a temporaryacceleration
in the growth of firm size and in industrial concentration and was
motivated by a desire for horizontalcombinationto suppress competition-especially price competition.' It was dependentmainly on events
in the immediatelyprecedingperiod, particularlythe depression of the
1890s, the spreadof generalincorporationlaws, and the development of
tradingin industrialsecurities on the New York Stock Exchange. The
other view sees the mergerwave as a structuralchange. More stress is
placed on the existence of previously unexploited economies of scale,
and, consequently, the rise of large factories is said to date from this
T
period.2
New data on the timingof increases in factory size, discussed in detail
below, indicate that the first view of the mergerwave is correct. If the
merger wave was primarilymotivated by the existence of unexploited
economies of scale, it would, presumably,have been followed by large
increases in the size of the average plant or factory (and, most likely,
permanent or long-lived increases.in concentration). If, on the other
changes in manufacturhand, the most importantstructure-determining

ing had taken place earlier, in the 1870sand 1880s, and if these changes
had already been exploited, then increases in average plant or factory
size should have been greaterduringthe 1870sand 1880sthan duringthe
period of the mergerwave.3
I. THE OPPOSING
VIEWS
Some good reasons exist for doubtingthe importanceof the long-run
impact of the merger wave. J. Fred Weston, after considering the
meager evidence on the state of industrialconcentrationprior to 1890,
warned that: ". . . care should be exercised to avoid exaggeratingthe
effects of the early mergermovements on industrialconcentration." He
concluded that many of the firms involved in the merger wave were
already large absolutely and relative to their markets and that "appreciable concentration" already existed prior to 1898.4
Many firms created during the merger wave subsequently failed.
Shaw Livermorecompiled a list of 156consolidationsduringthe period
1890 to 1905 that "could rightfully claim to be mergers with power
enough to influence markedly conditions in their industry. . . ." Of
these, 63, or 40.4 percent, failed financially;53 failed within 10 years of
being founded; and another 17 were only "limping" successes. A
second groupof 172less importantmergerscontained78 failures and 11
limpingsuccesses.5 Similarly,George Stiglerestimatedthat for a sample
of 19 manufacturingindustries, 14 experienced substantialdecreases in
concentrationbetween 1904and 1937, 4 experienced minor changes in
concentration, and only one-the automobile industry-experienced a
substantialincrease in concentration.6There is also some aggregatedata
available. G. Warren Nutter estimated that 32.9 percent of national
income originatingin manufacturingin 1904was producedin industries
whose four largestfirmsaccounted for 50 percent or more of sales some
I There is a possibilitythat economies existed in the late 1890sthat could have been reapedby
combiningseveral independentlyowned plants into one firm, withoutexpandingthe size of any
individualplant. The reapingof multi-planteconomies has never been proposedas an important
motive behindthe mergerwave. For instance,the distributionaland organizationalchangesAlfred
Chandlersees as importantsources of efficiencygains in the evolutionof the modem corporation
do not requirea multi-plantorganization.Furthermore,the carefulanalysis by F. M. Schererand
in the post-WorldWarII period
his colleaguesof multi-planteconomiesin Americanmanufacturing
has found them to be quite small. F. M. Scherer, et al., The Economics of Multi-Plant Operation:

time between 1895 and 1904.7In 1935, the first subsequent year for
which a comparableestimate is possible, 20.4 percent of all value added
in manufacturingoriginated in industries whose four largest firms
accounted for 50 percent or more of sales.8 This is a substantialdecline
in concentration.
Two recent studies support the view that economies of scale played
only a minorrole in the mergerwave. John James estimated production
functions for a small group of manufacturingindustries during 1850 to
1890.9The rate of labor-saving technological change, he found, was
greater in industries in which concentration increased significantlyat
the end of the century than in industries in which it did not. He
concluded that at least part of the increase in concentration that had
occurredby the end of the century was due to increases in optimalfirm
size.10 James is not clear, however, in specifying whether or not
economies of scale were largely reaped by 1890, in which case they
could not have caused the mergerwave. The extent of the labor-saving
technologicalchange James identifiedas having occurredpriorto 1890,
leads one to suspect that the fundamentalstructuralchanges in American manufacturingdate from thatperiod. A similarimpressionis gained
from readingAlfred Chandler'snow-celebrateddiscussion in The Visible Hand. Chandlerargues that the large, integratedmodern business
enterprisebased on high-volume,continuous-processproductiontechnologies or on marketing and distributionalinnovations had already
appeared during the 1880s in industries such as food processing,
chemicals, petroleum, primarymetals, machinery, and transportation

of James'sparticularestimates,clearlysome but not all mergeractivityhadits roots in the ongoing
process of capital deepeningand increases in optimalplant size. The argumenthere is that the
period of most rapid capital deepening and increases in plant size considerablyantedatedthe

of lasting importancehas many adherents. Ralph Nelson notes: "[The
merger wave] transformedmany industries, formerly characterizedby
many small and medium-sizedfirms, into those in which one or a few
very large enterprisesoccupied leading positions."'12 Economic history
textbooks, usually good reflections of the prevailing views among
economic historians, also emphasize the importance of the merger
wave. Several offer numericalestimates indicatingthat the rise of large
factories dates from the merger period. According to Robert Puth,
employment in the "average productionunit" in American manufacturing tripled between 1900 and 1920. Albert Niemi states that the
number of employees per manufacturingplant quadrupledduring the
same period, while Ralph Grey and John Peterson state it increased by
50 percent.'3 Although differingin detail, these accounts all reflect the
sense that average factory size increased slowly to 1900 and then
rapidly.
During the last decade criticism of the Department of Justice for
undervaluingthe efficiency gains from mergers has increased.'4 The
economists making this criticism have tended to see important efficiency gains from the great mergerwave. Yale Brozen argues that the
failureof the federalgovernmentto forestallthe mergersof 1898to 1902
benefited the economy and that a vigorous antimergerpolicy would
have forestalled substantialincreases in efficiency:
Concentratedindustries become concentrated (and some firms become and remain
"dominant")because that is the road to greater efficiency and lower costs in those
industries.... The increased concentrationbroughtabout by substantialhorizontal
mergers [early in the century] lowered prices relative to those in industries where
concentrationwas not increasedby mergers.'5

15 Brozen, Concentration,pp. 11, 65 (emphasisin original). In makingthis assertion Brozen
relies on a 1929 National IndustrialConference Board study. This study shows that for 16
industriesin which significantconsolidationshad taken place, wholesaleprices fell by an average
of 13 percentbetween 1900and 1913,while for 17industriesin which no importantconsolidations
had taken place, wholesale prices rose by an averageof 11 percent. Brozen interpretsthe price
declines as resultingfrom the cost reductionsmade possible by merger.A more likely interpretation is that they representthe erosion over time of the supracompetitiveprices the consolidations
had been able to charge.The latterinterpretationis consistentwith the workof DariusGaskinson

Althoughtheir reasons differ, the authorscited above see the merger

II. NEW MEASURES
OF FACTORY
SIZE
New measures of the timing of increases in factory size in American
manufacturingindicate that it is unlikely the typical consolidation
formed duringthe mergerwave took advantageof previously unreaped
economies of scale. The conventionalmeasureof factory size is its level
of physical output (on the assumptionthat it is producingat capacity).
A difficultyarises, however, in using census data on value of production
(or value added) per factory because complex price level and relative
price adjustment problems arise (especially when, as here, disaggregated measures are also needed).
Average capital stock per factory and the average level of employment per factory are alternative measures. The former might be
preferred, because the usual account of economies of scale in late
nineteenth-centurymanufacturinginvolves a process of rapid capital
accumulation."6There are, however, two problems with the census
capital stock data. One is they, too, require deflation; although the
difficultyis not as great as with the value of productiondata, errors of
unknown magnitudemay be introducedinto the analysis. The greater
problem lies in the fundamentalunreliabilityof the capital stock data.
Every census duringthe periodcontains warningsabout the accuracy of
the reported capital stock figures.17
The most reliable measure of factory size would seem to be average
employmentper factory.18 The measureis not without problems. Using
average employment of wage earners per factory as a measure of
minimumoptimal scale of productioncould lead to misleadingresults if
labor-savingtechnologicalchange caused the minimumoptimalscale as
measuredby volume of productionto increase without a corresponding
increase in employment. In that case rapid increases in manufacturing
output would be observed duringperiods when employmentgrew little.
In fact, as discussed below, factory size as measured by wage earner
employment grew more rapidly during the 1869 to 1879 decade than
during the 1889 to 1899 or 1899 to 1909 decades, while, according to
John Kendrick's estimates, output per worker in manufacturinggrew
more rapidlyin the latter decades. Hence, the main aggregateresults of
this article cannot be artifacts of the effects of labor-savingtechnolog16 See

ical change.'9 Furtherreassurancecomes from the work of Louis Cain
and Donald Paterson. Their work allows a rankingof eighteen two-digit
SIC industries by the extent of labor-savingtechnical change experienced between 1850and 1919.20These industriesmay also be rankedby
increases in the average employment of wage earners per factory
between 1869and 1919.21The two rankingsare strongly and positively
correlated, indicatingthat even over a long period of time and focusing
exclusively on labor-saving change, the more rapid technological
change was in an industry, the largerthe increase in wage earners per
factory.22
Two potential difficultiesarise in using the census employment data
for factories. First, the census collected data on "establishments" not
"factories." In all censuses during the period, data on two or more
factories owned by the same firmand located in the same county were
reportedas a single establishment,but, as is discussed below, this is not
a problem.23Anotherpossible difficultyis that the census twice changed
the types of establishments enumerated. Prior to 1904, the census
included production taking place outside of factories in "hand and
neighborhood"industries.24Beginningin 1904,only factory production
was included. I therefore exclude from the estimates industries with
significant production in hand and neighborhood industries. Prior to
1914, establishments producing output valued at $500 or more were
included. Beginning in 1914, the lower limit was raised to $5,000. 1
handle this problem by constructing two sets of index numbers for
factory size, one from 1869to 1914and anotherfrom 1914to 1929. The
two indexes are linked in 1914 when the change in enumeration
occurred.
Table 1 presents informationon averagenumbersof wage earnersper
establishment. The importance of the changes in census coverage is
evident. An index of factory size computedusing the data is given in the
last column. The index is not reliable for years prior to 1899 because
movements in it may be produced by changes in the hand and neighborhood industries. Eliminatingthe hand and neighborhoodindustries
from the census data leaves 171 industries for which data on factory

rankingis based on the size of the regressioncoefficientsreportedin table I of Louis P.
Cain and Donald G. Paterson, "Factor Biases and Technical Change in Manufacturing:The
AmericanSystem, 1850-1919,"this JOURNAL, 41 (June 1981),pp. 341-60. It should be noted that
because Cain and Patersonmake use of census capitalstock data, their estimates are suspect.

The index reveals that almost two-thirdsof the increase in factory size
that was to take place between 1869 and 1929 had occurred by 1889well before the beginningof the mergerwave.28Transformingthe index
into average annual rates of change, given in the third row of Table 2,

ical and organizationalinnovations of the 1870s and 1880s and that the
great mergerwave cannot be explainedby unreapedeconomies of scale.
There does appearto have been an accelerationin the increase in the
average numberof wage earnersper establishmentin the period 1899to
1904, following the mergerwave. But this does not indicate that newly
combined firmsexpanded to achieve minimumoptimal scale. First, the
period 1904 to 1909 witnessed a decline in the average employment of
wage earners per establishment.This is consistent with other evidence
concerningthe failureof many mergersundertakenduring1898to 1902,
suggestingthey did not benefitfrom scale economies. Second, a merger
involving firmsproducingthe same productin the same locality would,
given the census definition of establishment noted above, reduce the
numberof reportedestablishments,even if no physical consolidationof
establishmentshad taken place. Hence, some of the measuredincrease
in factory size is illusory because some factories that continued to
produce were dropped from the census returns. This thesis can be
assessed using the 171 industriesfor which full informationis available
for all census years between 1869 and 1919. Of the 53 industries that
experienced their greatest increase in wage earnersper establishmentin
the 1899 to 1904 period, almost 70 percent experienced a decrease in
establishments. Only 49 percent of industries that experienced their
greatest increase in wage earners per establishmentduringsome other
period experienced a decline in reportedestablishmentsfor that period.
The differencebetween these two proportionsis statistically significant
at the 1 percent level.
It is by no means clear that the mergerwave was the dominantfactor
increasing factory size even in the 1899 to 1904 period. Table 3 ranks

and each of the two measures of mergeractivity are positive, neither is
statistically significant.To point out two particularinconsistencies, the
table indicates that while the primarymetals productsindustry(SIC 33)
experienced the most merger activity, there was no corresponding
increase in average factory size. Conversely, the stone, clay, and glass
products industry (SIC 32) experienced a large increase in average
factory size, while undergoinglittle mergeractivity.

reinforcedby data disaggregatedat the two-digit SIC industry level.29
These data are presented in Table 4 and indicate that in all manufacturing industriesin which, accordingto Chandler,large integratedmodern
business enterprises were most characteristicallyfound, factory size
increased more rapidly before 1889 than after.30This is not surprising
because many of the technological innovations that allowed for the
initialdevelopmentof largefirmsin these industriesappearedduringthe
29 The distributionof census industriesamongcurrenttwo-digitlevel classificationsis consistent
with the categorizationin Albert W. Niemi, Jr., State and Regional Patterns in American
Manufacturing:1860-1900(Westport,1974).
30The industries referred to are: food processing, chemicals, petroleum, primary metals,
machinery,andtransportationequipment;see Chandler,"Seedbedof ManagerialCapitalism,"pp.
28-29; and Cainand Paterson,"FactorBiases," p. 354, fn. 24. In most of these industriesfactory
size actually increasedfaster between 1889 and 1899than between 1899 and 1909. Thus, even
Chandlerwould seem to have overestimatedthe efficiency gains from the merger wave; see
Chandler,The VisibleHand, pp. 331-39.

31 In Chandler'sview, these innovationsincludecontinuous-processmachinery,which allowed
for mass production,and refrigeratedrailroadcars, which allowedfor mass distribution.Chandler
also discusses purely organizationalinnovations, such as the meat storage and retail delivery
systems set up by GustavusSwift.

flour, refrigeratedcars in meat packing, the pneumaticmaltingprocess
and temperature-controlledtank car in brewing, and food preparation
and can-sealing machinery allowed for the mass productionof canned
meat, vegetables, fish, and soups. During the 1880s, the chemical
industrysaw the introductionfirstof the Solvay and then the electrolytic
processes in the productionof alkalis, and the discovery of the process
of producingacetic acid and acetates as byproductsof charcoalproduction. In the petroleum industry, John Merril's development of the
seamless wrought-iron or steel-bottomed still allowed for a sharp
increase in plant size between 1867 and 1873.32The 1870s saw the
development of the long-distance crude oil pipeline and the steel tank
car. In the 1870s and 1880s the Bessemer and open-hearthprocesses
were widely adopted in steel making. In the mid-1880s, new developments in electro-metallurgy made commercial mass production of
aluminumpossible. Duringthe same period, a large numberof mechanical and chemical innovations were devised that greatly facilitated the
process of refining and working various metals. The development,
beginningin 1880, of improved metal-workingmachinerybased on the
use of high-speed-toolsteel allowed for the productionof a wide variety
of better machines with finertolerances. The typewriter,invented in the
late 1870s, was mass produced duringthe 1880s. The electrical street
railwaycar came into widespreaduse duringthe late 1880s. In addition,
of course, the basic transcontinentalrailroad and national telegraph
networks-infrastructure necessary for the rise of firms capable of
distributingproducts on a nationalbasis-were complete by 1880.33
The conclusion, then, is that the role of the great mergerwave of 1898
to 1902 in the evolution of the American economy should be downplayed; instead greater emphasis should be placed on developments of
the 1870sand 1880s. Increases in concentrationduringthe mergerwave
were motivated more by the desire to reduce price competitionthan by
the desire to exploit scale economies. The contrary view is not
consistent with the extent to which increases in concentrationthat took
place from 1898to 1902in many industrieswere subsequentlyreversed
or with the estimates presented here on the growth path of average
factory size. It has not been previously recognized that in American
manufacturing,particularlyin the most modernand progressivesectors,
factories grew in size more rapidly duringthe 1870s and 1880s than at
any time thereafter, at least throughthe 1920s.
