Abstract
We examine the time series data on firm entries and exits in the East Liverpool (Ohio)
pottery industry between 1825 and 2010. The purpose is to identify patterns in the
movement of the firms as well as their spans of life over the course of the industry’s
development. Two patterns emerge: 1) the numbers of entries and exits are positively
correlated; 2) the life spans of all firms that existed over the industry’s life-cycle show
significant “infant mortality.”

1. Introduction
Industrial migration from Britain to the United States has been a significant part of the formative
history of many major industries – e.g., textiles, mining, iron and steel. Though much smaller in
scale, the development of the American pottery industry followed the same migratory pattern.
The massive migration started in early 1800s, mostly by the journeymen potters with skills but
little capital.2 According to Thistlethwaite (1958), the migration of English potters had a single
origin, the Five Towns of Staffordshire, but two destinations, East Liverpool, Ohio and Trenton,
New Jersey. With the high rates of tariff imposed on English imports following the Civil War,
the twin centers of domestic ceramic production grew rapidly in the late 19th century to dominate
the domestic market: “Trenton and East Liverpool were the centers of production in the two
leading ceramic manufacturing states. These two centers produced 49.7 percent of all pottery
products manufactured in the United States at the turn of the century.” [Gates (1984)]
This short note explores the entry and exit dynamics of the firms throughout the formation,
growth, and the eventual decline of the pottery industry located in East Liverpool, Ohio. Its
purpose is to identify patterns in the movement of the firms as well as in the distribution of their
spans of life over the entire life-cycle of the industry. Two patterns emerge from this study: 1)
the numbers of entries and exits are positively correlated so that the period with a high number of
entries is also the period with a high number of exits and vice versa; 2) the life spans of all firms
over the industry’s life-cycle show infant mortality.
2. Data
The dataset used for our study is constructed from the list of companies that operated in East
Liverpool over the period of 1826 to present, as compiled by William C. Gates, Jr., Curator of
History for the Ohio Historical Society.3 According to this list, the earliest recorded date of
pottery production in East Liverpool is by Joseph Wells in 1826. The list contains a total of 292
firms. The dates of entry and exit are provided for 275 firms. Out of these 275 firms, 267 of
them went out of existence, while eight still remain in operation. The full list with the company
names, their years of operation and the life spans is provided in the Appendix.
For the population of 275 firms with entry and exit dates, some modifications had to be made. If
a firm exited the industry but re-entered the market under the same name at a later date, the

Thistlewaite (1958): “In 1815, …, potting was still in its infancy in America: a matter of primitive kilns, scattered
up and down the seaboard producing coarse wares for parochial markets. Men still had to learn to fire the native
clays; to discover clay banks near coal seams; to build the canals and railways which would transport coal to clay
and the bulky, fragile ware to distant markets; to find capital; to raise a tariff against the cheap and professional
wares dumped on the American market from the British potting metropolis; and to overcome native prejudice
against domestic wares. But above all, to establish an industry which derives from an ancient craft, it was necessary
to await the immigration of ‘practical potters’, men with generations of potting in their blood, journeyman-graduates
of an exacting apprenticeship, with an instinct for the chemistry of clays, sensitive to texture and form, skilled in
throwing, turning, in the making of moulds and in decorating. During the nineteenth century thousands of such men
emigrated to the United States to provide the essential cadre of artisans for a native pottery. And although some of
the early potters were French and German, the very great majority came from Staffordshire.”

1 company was treated as having entered and exited the market twice. The Appendix will have
“episode I” or “episode II” by the firm name to represent this fact. In some cases, a firm
appeared to have left the market but was continuously still operating under a different name.
Typically, the name change reflected the addition or deletion of one or more co-owners or it
reflected the incorporation of a firm. If this was the case, these separate firms were merged into
one firm. For example, the Laughlin Brothers firm was opened in 1873 and technically exited
the market in 1877 when one of the Laughlin brothers left the firm. However, the other Laughlin
brother continued to operate the firm under the name Homer Laughlin. In 1896, the firm was
incorporated and then called the Homer Laughlin China Company. The firm continues to
operate today. In this case, the lineage of the firm was able to be traced and, instead of having
three separate entries, the company was treated as one firm that began in 1873 and operates to
this day. The list of all firms in the Appendix includes these “merged” firms that have the
comment “see note” in the comment section.
3. Entry, Exit, and Industry Structure
Starting with 1825, Figure 1 plots the time series over 186 years of the number of entries,
, and the number of exits,
. The persistence of these movements in and out
of the industry throughout the horizon is noteworthy. More importantly, however, these time
series appear to move in concert, though imperfectly. The table below shows the correlations
between the two series with up to five periods of lag for the number of exits:
,
0.360394
,
0.684669
,
0.439309
,
0.490466
,
0.346086
,
0.468828
and
are positively correlated so that the year having a relatively large
First, note that
number of entries is also the one with a relatively large number of exits.4 More interestingly, the
positive correlation is at its highest when the number of exits is lagged by one year. This
suggests a shakeout process operating throughout the horizon, perhaps as the result of random
external shocks (either in demand or supply) that were unanticipated by the producers.
While both entry and exit persist over time, we do observe that, on average, there are net entries
in early years (up to about 1900), while there are net exits in the later years. This leads to Figure
2, which shows the total number of operating firms over the same horizon. Both the rise and the

decline of the industry along its life cycle are apparent in this figure. Some noticeable peaks and
troughs are precisely indicated with the corresponding years.
4. Life Spans of Firms
Inspecting the list of firms, one can see that there are substantial variations in their life spans; the
short-lived ones with only one year of operation and the long-lived ones with over 125 years. To
see the distribution of the firms’ life spans, let us create bins, each with up to five years of life
span: that is, the first bin with firms having a life span of 1 to 5 years; the second bin with those
having a life span of 6 to 10 years; the third bin with firms having a life span of 11 to 15 years,
and so forth. Excluding the eight firms that are still in business, we count the number of firms in
each bin. In Figure 3, we plot these numbers in a bar graph. It clearly shows a phenomenon of
infant mortality, in which a disproportionately large number of firms lived for less than 5 years.
The number of firms belonging to each bin of longer life spans drops down rapidly, as shown in
the figure.
While Figure 3 shows the phenomenon of infant mortality, one may further inquire about what
happens with even shorter life spans. In Figure 4, we have divided the 5-year bins into singleyear bins for up to 20 years of life span. The resulting histogram shows that a significant
proportion of firms exit the market within the first year.
5. Discussion
Several comments are in order. First, both the infant mortality and the positive correlation
between entries and exits have been observed in the empirical literature in industrial
organization. For instance, our findings are in line with three of the stylized facts presented by
Geroski (1995): 1) “Entry is common. Large numbers of firms enter most markets in most years,
but entry rates are far higher than market penetration rates”; 2) “Entry and exit rates are highly
positively correlated, and net entry rates and penetration are modest fractions of gross entry rates
and penetration”; 3) “The survival rate of most entrants is low, and even successful entrants may
take more than a decade to achieve a size comparable to the average incumbent.”
Similarly, Caves (2007) states:
Turnover in particular affects entrants, who face high hazard rates in their infancy that
drop over time. It is largely because of high infant mortality that rates of entry to and exit
from industries are positively correlated (compare the obvious theoretical model that
implies either entry or exit should occur but not both). The positive entry-exit correlation
appears in cross-sections of industries, and even in time series for individual industries, if
their life-cycle stages are controlled. [Caves (2007: 9-10)]
Further evidence is provided by Geroski and Mazucato (2001) who examined the 93 years of
data on the population of domestic U.S. auto producers. They found that the number of entrants
and the number of exiting car producers between 1895 and 1967 are positively correlated
(0.6086).
3 Second, the simultaneous occurrences of entry and exit suggest a pervasive heterogeneity among
firms, either in terms of the product characteristics or in terms of production technologies held by
them. Unanticipated shocks to consumer preferences over product attributes or to production
technologies (possibly through changes in relative input prices) can then affect the firms
unequally, thereby simultaneously inducing entries of those who are favorably affected and exits
of those who are adversely affected. Of course, such inter-firm heterogeneity can be a persistent
source of the phenomenon in question, only if there are inherent frictions in the market which
prevent the firms from instantaneously copying the most preferred product or the most efficient
technology.
Third, the striking degree to which our findings show the presence of infant mortality suggests a
limitation in the textbook models of market competition, in which firms are characterized as
rational optimizers having perfect foresight. The entry and exit behaviors of the firms in our
study simply do not conform to this standard. This leads to our final point that the study of
industry dynamics may benefit from theoretical work involving firms with bounded rationality.5
Efforts in this direction, using computational methods, are made in Chang (2009, 2011b, 2012).6

While there have been attempts to incorporate bounded rationality into industrial organization, much of this work
has focused on modeling the consumers as being boundedly rational, while keeping the firms as profit-maximizers
with perfect foresight. [See Spiegler (2011).]
