ABSTRACT

Mittlelstaedt,  Harben, and Ward (2003) and Wolff and Pett (2000) offer contradictory 
evidence on the impact of firm size (by employment) and the propensity to export. Using a 
data set very similar to that of Mittelstaedt et al., we re-examine the issue. Although we find 
that firm size has a significant impact on export propensity, we fail to find a threshold at 
twenty employees, as Mittelsteadt, et al., did. Our findings are more supportive of Wolff and 
Pett, who argue very small firms are capable of exporting. This paper concludes by 
considering the implications for researchers and policymakers.

INTRODUCTION

Exporting by small firms is a significant 
economic activity. The U.S. Bureau of 
Census indicates that over 239,000 firms 
exported goods in 2005.  Small companies 
account for 97 percent of all U.S. exporters, 
a percentage that has risen slightly since 
1995. Small exporters exported goods valued 
at $228 billion,  which represented 29.1 
percent of total U.S. goods exported (U.S. 
Census Bureau, 2007).  

McDougall and Oviatt (1999) are credited 
w i t h i d e n t i f y i n g a l i n k b e t w e e n 
internationalization and entrepreneurship. 
However, they expressed caution that the 
“born global” phenomenon was universally 
appealing to all firms, regardless of size. 
Their caution was guided by the fact that 
they noted that there was largely no 
empirical support for the recommendation 
that firms internationalize.

Given figures such as these,  it is unsurprising 
that the academic literature explores the 
relationship between firm size (by number of 
employees) and exporting (see Wolff and 

Pett,  2000, and Mittelstaedt, Harben, and 
Ward, 2003). Although there any many ways 
for firms to internationalize, like much of the 
literature, we focus on exporting. The 
findings are inconsistent in this area. Some 
studies identified a positive relationship 
between firm size and export success (e.g., 
Lall and Kumar,  1981; Kaynak and Kothari, 
1984). Other studies found no relationship 
(e.g., Czinkota and Johnson, 1983; and 
Moini, 1995).  Finally, another group of 
studies found an inverse relationship (e.g., 
Cooper and Klienschmidt, 1985).

Mittelstaedt,  Harben,  and Ward (2003) 
argued that firms with fewer than 20 
employees (hereafter,  micro firms) fall below 
a critical threshold and will face so many 
major obstacles to exporting that they should 
not attempt to export.  However, their 
conclusions contrasted with Wolff and Pett 
(2000),  who argued that micro firms are 
capable of exporting, and with McDougall, 
Shane, and Oviatt (1994) and Oviatt and 
McDougall (1995) and others (e.g., Autio, 
Sapienza, and Almeida 2000; Rialp-Criado, 
Urbano, and Vaillant 2003),  who argued that

some new ventures are created with an intent 
to sell internationally.  

The purpose of this paper is to revisit the 
relationship between firm size and export 
propensity,  focusing on micro firms,  using 
Mittlelstaedt et al (2003) and Wolff and Pett 
(2000) as our antithetical backgrounds,  and 
using a data set very similar to that of 
Mittelstaedt et al.  We argue that Mittelstaedt 
et al. did not prove that micro firms are 
i n c a p a b l e o f e x p o r t i n g , b u t i n s t e a d 
demonstrate that micro firms are less likely 
to export. Their 20-employee threshold is not 
an absolute value,  but is the result of the 
specific method Mittelstaedt et al. used to 
analyze their data. Although we find that 
firm size has a significant impact on export 
propensity,  we fail to find a threshold at 
twenty employees. Instead, we find that the 
evidence supports the existence of a 
“threshold” at any arbitrarily chosen 
partition value; that is, the evidence fails to 
support the existence of a threshold at any 
particular number of employees. Our 
findings are supportive of the Wolff and Pett 
argument,  which said very small firms are 
capable of exporting.  

This is not a trivial result. Where there are 
inconsistent results in the literature—
inconsistencies in what we know—there is 
the increased likelihood of poor public 
policy and poor business strategy decisions. 
The two practical end products of academic 
research in business are advice for public 
policy makers and advice to business 
strategy makers.  Academic research would 
fail in this regard if, for example, micro 
business owners or business assistance 
professionals fail to pursue exporting until a 
firm has grown to a certain threshold size 
because of a mistaken academic result. 
Academic research would fail in this regard 
if, for another example, policymakers fail to 
pursue the idea that economic development 
can occur through exporting by micro firms 
because of a mistaken academic result. We 
do not claim to have conclusively resolved 
the empirical inconsistencies in the 
relationship between firm size and exporting.  
However, we do provide another piece of 
evidence that moves us in that direction.

In the next section, we provide a brief review 
of the literature on exporting by small firms 
with a particular emphasis on size as a 
determinant of exporting ability.  Then,  we 
describe our research design and discuss our 
results using a sample of firms obtained from 
a database of over three thousand firms 
m a i n t a i n e d b y t h e S o u t h C a r o l i n a 
Department of Commerce. In the final 
section, we discuss the implications of our 
findings and make suggestions for both 
future research and public policy officials.

LITERATURE REVIEW

Small firms and micro firms have emerged 
as one of the most widely researched topics 
of the last 30 years (Wright, 1993; Autio, 
Sapienza, and Almeida, 2000; Baird, Lyles, 
and Orris,  1994; Aitken, Hanson,  and 
Harrison, 1997; and Oviatt and McDougall, 
1995). This section will emphasize particular 
research relevant to firm size as a 
determinant of exporting. While other forms 
of market entry are available to small firms, 
exporting remains a significant means of 
foreign market entry (Pett and Wolff,  2003; 
Hollenstein, 2003) and is the focus of this 
paper.

Several studies have measured performance 
outcomes in terms of export performance or 
export intensity,  with mixed results. Some 
studies found a positive relationship between 
firm size and export success (e.g.,  Lall and 
Kumar, 1981; Kaynak and Kothari,  1984). 
Other studies found no relationship (e.g., 
Czinkota and Johnson, 1983; and Moini, 
1995). A final group of studies found an 
inverse relationship (e.g., Cooper and 
Klienschmidt, 1985). 

A study from the first group,  Baird,  Lyles, 
and Orris (1994), found that international 
firms are larger and tend to be industrial 
firms rather than retail or service firms.  
Dhanaraj and Beamish (2003) confirmed this 
finding using a resource-base theory of the 
firm (Penrose,  1959; Barney,  1991) in a 
sample of Canadian firms.  

Wo l f f a n d P e t t ( 2 0 0 0 ) , h o w e v e r , 
demonstrated that small firms are capable of 
exporting. They concluded that small firms 
use a different decision process to export 
than do large firms. They argued that the

resource-based view of the firm may serve as 
a useful explanation for the success of these 
small exporters. Very small firms in their 
study appeared to capitalize on unique 
r e s o u r c e s t h a t w e r e i n d e p e n d e n t o f 
economies of scale or other cost efficiencies.  

The results of Mittelstaedt et al. (2003) and 
Mittelstaedt and Ward (2005) are in sharp 
contrast to those of Wolff and Pett (2000). 
Using a sample of manufacturing firms in 
South Carolina, they found that micro firms 
are far less likely to engage in exporting than 
small firms with between 20 and 500 
employees (Mittelstaedt et al, 2003). 
Significantly, they found that firms behave 
as if 20 employees is a minimum threshold, 
b e l o w w h i c h f i r m s d o n o t e x p o r t .  
Mittelstaedt et al.  concluded that micro firms 
simply do not have the resources to engage 
in exporting. They concluded that “firm size 
serves as a necessary as well as a sufficient 
c o n d i t i o n f o r e x p o r t i n g 
success.” (Mittelstaedt, Harben,  and Ward, 
2003) They reasoned that “if minimum firm 
size is a necessary condition for export 
success, then exporting firms will be larger 
than non-exporting firms” in the same 
industry (Mittelstaedt, Harben, and Ward, 
2003). Our interpretation of their work is that 
t h e y v i e w e d e x p o r t i n g s u c c e s s 
dichotomously rather than intensively, 
wherein if a firm self-reported any amount of 
exports, then that firm is coded as a success. 
To test their hypothesis, they calculated the 
exporting conditional probabilities of firm 
size distribution within a given industry. 
T h e y c o m p a r e t h e c a l c u l a t e d s i z e 
distribution with the actual size distribution 
of exporting firms to determine whether 
c e r t a i n s i z e s o f f i r m s a r e 
“underrepresented” (Mittelstaedt, Harben, 
and Ward, 2003). They found that small 
firms are less likely to export than are large 
firms. Thus,  they write, “In the United 
States, how small is too small to export? The 
answer appears to be 20 employees,” (2003), 
and “The bad news for most firms with 
fewer than 20 employees is that they appear 
to be too small to acquire the knowledge or 
experience necessary to engage in the 
exporting process.” (2003).

A more recent study by Mittelstaedt and 
Ward (2005) also found a significant positive 

relationship between firm size and the 
propensity to export. However, in this study, 
the authors noted that their model captured 
not only a difference in export propensity 
between small and large firms, but also 
between micro firms and small firms.  

Researchers exploring the relationship 
between firm size and export propensity 
have continued to produce contradictory 
findings. For example, Thomas, and Grosse 
(2005) also suggested that firm size matters. 
Thomas and Grosse (2005), used size as an 
indicator of resource availability.  Their 
initial hypothesis is consistent with 
Mittelstaedt et al (2003). They argued that 
“firms that possess higher levels of resources 
are more likely to engage in exporting to 
exploit them” (Thomas and Grosse, 2005). 
However, their results did not show a 
positive relationship between firm size and 
export propensity.  They identified a positive 
r e l a t i o n s h i p b e t w e e n f i r m s i z e a n d 
importing. They point out that their study 
was limited to the study of the largest 
Mexican firms. Thus,  the authors noted the 
range restriction of their measure for firm 
size as a limitation, but noted that range 
restrictions are a significant problem with 
much of the research on internationalization, 
exporting, and firm size.  

Finally,  a recent study by Hollenstein (2005) 
argued that size may be a determinant of 
exporting, but only up to a certain size 
threshold (firms with up to 200 employees). 
Hollenstein’s analysis of a sample of Swiss 
firms was divided into three sub-samples to 
capture subsets based upon three primary 
size categories: small, medium, and large 
firms. Firm size was not found to exert an 
independent influence on internationalization 
in the sub-sample of large firms (greater than 
200 employees).

The contradiction between the conclusions 
of Wolff and Pett (2003) and Thomas and 
Grosse (2005), and the conclusions by 
Mittelstadt et al.  (2003), Hollenstein (2005), 
and others,  is more appearance than 
substance. We argue that Mittelstaedt et al. 
did not conclusively demonstrate that micro 
firms are incapable of exporting. Rather, 
they demonstrated that micro firms are less 
likely to export than larger firms. We argue 

                                                                                 Volume 19, Number 1 Spring/Summer 2008

that the 20-employee threshold is not an 
absolute value, but is the result of the 
specific method Mittelstaedt et al. used to 
analyze their data.  

METHODOLOGY AND RESULTS

We examined data from the 2000-2001 
South Carolina Industrial Directory to 
determine whether firm size serves as a 
necessary and sufficient condition for export 
success among small manufacturing firms. 
We used data drawn to replicate the 
Mittlelstaedt et al (2003) study. 1   More 
current versions of the South Carolina 
Industrial Directory are available, but we 
used the 2000-2001 edition to remain 
consistent with the prior study.  We believe 
this is a methodological strength for us, as it 
allows us to test their conclusion that 20 
employees are a necessary condition for 
exporting, using what is essentially their own 
data set.  

We examined the data to determine whether 
South Carolina firms with fewer than 20 
employees export. If 20 employees is a 
necessary condition for exporting, then one 
should be unable to observe firms with fewer 
than 20 employees actually exporting.

After sorting the dataset by SIC code,  we 
conducted chi-squared tests after partitioning 
the sample using arbitrarily chosen firm 
sizes. If, using a chi-squared test, we find 
evidence that an “exporting threshold” exists 
at an arbitrarily chosen cut-off number of 
employees, then the similarly derived 
evidence for a threshold at 20 employees 
will fail to persuade.

Mittelstaedt et al. examined 2,848 firms from 
49 three-digit SIC industrial sectors.  The 
current study from the same data set uses 
3,771 firms. The specific 49 sectors were not 
listed in the first paper, so our data could not 
be restricted to these sectors.  

We wish to emphasize what constitutes an 
“exporting firm” for the purposes of this 
paper, given the dataset we used. The data 
recorded self-reported answers measuring 
whether a firm exported during the year,  on a 

“yes” or “no” basis. Thus, if a firm reports 
exporting, we coded that firm as an export 
success. The data did not allow us to 
measure sales volume or profit volume of 
exports, nor did it allow us to measure export 
intensity or export intentions.

It is helpful to plot the data, as shown in 
Figure 1, to obtain a general understanding 
of the data.  Figure 1 shows the percentage of 
firms that export by the number of 
employees in the firm (from 0 – 500 
employees). Figure 2 is identical to Figure 1, 
except it emphasizes very small firms (0 – 50 
employees). As most research suggests, 
Figure 1 shows that larger firms are more 
likely to export than smaller firms. The 
figure shows that 15 percent of firms with 
one employee export and this percentage 
gradually increases with no discontinuities 
until 37 percent of firms with 500 employees 
export.  Figure 1 and Figure 2 plot the 
number of employees against the cumulative 
percentages of firms that export. For 
example, 37 percent of all firms with up to 
500 employees export. The cumulative 
percentage is used to reduce random 
fluctuations in the exporting percentage of 
firms with different number of employees. 
The random fluctuations make interpreting 
the graph very difficult.

Visual observation of the raw data does not 
appear to support the Mittelstaedt et al. 
conclusion that micro firms with fewer than 
20 employees cannot export. Although larger 
firms are more likely to export, micro firms 
in South Carolina do export over the 
observation period,  and the data show no 
unusual patterns around the 20-employee 
mark.  Figure 2 emphasizes very small firms 
and shows that 44 percent of firms with zero 
employees export. A firm with zero 
employees would be a self-employed person 
with no additional employees.  Remember, a 
self-employed person is not an employee of 
the firm.  This export percentage is higher 
than the average export percentage of any 
other level of employment. This observation 
is consistent with anecdotal evidence that 
micro firms with a web site or eBay presence 
will export. The results are qualitatively

unchanged if we censor our sample to 
exclude zero-employee firms.  Although the 
percentage of exporting companies falls after 
censoring the data, it never dips below 15 
percent of firms. Whether we include or 
exclude zero-employee firms in our sample, 
the evidence indicates that a sizeable portion 
of micro firms are exporting.

Mittelstaedt et al. sorted the South Carolina 
firms by three digit SIC  codes and then 
partitioned each selection of firms into four 
groups: micro (fewer than 20 employees), 
small (20-99 employees), medium (100 – 
4 9 9 e m p l o y e e s ) , a n d l a r g e ( 5 0 0 + 
employees). They counted firms that export 
and firms that do not export by SIC 
classification within each size group. They 
performed Chi-square tests on each SIC 
classification. They found 31 of the 49 SIC 
classifications studied have statistically 
significant differences across firm sizes.  

Mittelstaedt et al.  gave a very helpful 
example on pages 71-72 of their paper, in 
which they demonstrated their analytical 
technique in detail for one business sector, 
rather than simply reported 49 chi-squared 
test results. We followed their lead, and also 
analyzed one sector in detail, as an 
illustrative example of the general procedure. 
The example concerns SIC code 355 
(Special Industry Machinery and Equipment) 
which has a total of 120 firms, which they 
partitioned by number of employees. Please 
see the left-hand side of Table 1,  wherein we 
offer a similar example, with the data 
partitioned as Mittelstaedt et al. did.  

The left-hand side of Table 1 shows the 
numbers of firms that export and do not 
export in each partition,  and also shows the 
calculation of the chi-square test. We 
calculated the expected values by assuming 
that the average percentage of firms 
exporting within the sample will be the same 
as the average percentage of firms that 
export within each partition. This is what one 
would expect if there were no relationship 
between firm size and export propensity. For 
example, 63.33 percent (76 firms out of 120 
firms) of the firms in this SIC classification 
choose to export.  Therefore, 63.33 percent of 
firms will export in each partition. Of the 70 

micro firms, we expect that 44.33 of these 
firms will export.  

This analysis creates an allocation exercise; 
therefore,  the actual value minus the 
expected value is a zero sum calculation. 
That is, the actual number of firms that 
export (and do not export), minus the 
expected number of firms that export (and do 
not export), sum to zero across the columns 
and down the rows. Therefore,  when firms in 
some categories export more than average 
(i.e.,  large firms), then it follows that firms in 
some other category will have to export less 
than average (i.e., small firms). We then 
calculated the sum of squared errors. The test 
statistic was formed by the total sum of 
squared errors, and takes a chi-squared 
distribution.  Figure 1 and Figure 2 show that 
small firms export less, therefore any 
partition of firms according to SIC code will 
show that smaller firms export less than 
larger firms. This is what Table 1 shows: 
statistically, significantly fewer firms than 
expected export within the “under 20 
employees” partition.  Our conclusion is that 
size matters, and we reject the hypothesis 
that there is no relationship between firm 
size and export propensity.

Rather than demonstrating that firms with 
fewer than 20 employees are too small to 
export, this example (and the original 
examples in Mittelstaedt et al.) shows that 
micro firms do export; albeit a smaller 
percentage of these firms export than would 
be expected based upon the average of all 
firms in SIC code 355.  This argument is 
consistent with the evidence obtained from 
Figure 1 and Figure 2.  Contrary to the 
Mittelstaedt et al.  assertion (2003), firm size 
is not a necessary condition for exporting 
success, whether firm size is fewer than 20 
employees or more than 20 employees.  

The Mittelstaedt et al. finding that firms with 
fewer than 20 employees are too small to 
export is a result of their particular partition 
of the dataset at 20 employees.  To 
demonstrate this, we partitioned the data 
using arbitrarily chosen threshold figures, to 
determine whether the data also supports any 
arbitrarily chosen partition as an export 
threshold. We partitioned the data from SIC 
code 355 into firms with fewer than 100

employees, firms with 100-200 employees, 
firms with 200-500 employees, and firms 
with more than 500 employees. We report 
the results on the right hand side of Table 1. 
This example shows that 4.40 fewer firms 
with less than 100 employees export than 
would be expected. The test statistic reveals 
statistically significant differences. The p-
values indicate statistically significant 
differences in export propensity across 
differently sized firms, and indicate that 
smaller firms are significantly less likely to 
export than larger firms.  However, as the 
right-hand column indicates,  the number of 
employees at which this threshold occurs is 
arbitrary and at the choice of the analyst.

Therefore, the data provides the same 
support of the existence of a threshold at an 
a r b i t r a r y d i v i s i o n o f t h e d a t a ( 1 0 0 
employees) as it does for the Mittelstaedt et 
al. division of the data at twenty employees. 
The evidence for the existence of an 
exporting threshold at 20 employees is not 
compelling, and we view the existence of an 
exporting threshold at 20 employees as 
possible, rather than conclusive. Our analysis 
of a very similar data set fails to support the 
Mittelstaedt et al. conclusion that “firm size 
serves as a necessary as well as a sufficient 
condition for exporting success” (2003). Our 
evidence does support the conclusion of 
Wolff and Pett (2000) and others who 
conclude that even micro firms are capable 
of exporting.

RESEARCH AND POLICY 
IMPLICATIONS

Although we find that firm size has a 
significant impact on export propensity, we 
fail to find a threshold at twenty employees. 
In fact, we find that even the smallest firms
—those with zero or one employees—are 
capable of exporting. We find that 20-
employee threshold is not an absolute value, 
but is a result of the specific partition of the 
dataset. We find that the evidence supports 
the existence of a “threshold” at any 
arbitrarily chosen partition value; that is, the 
evidence fails to support the existence of a 
threshold at any particular number of 
employees. Our evidence fails to support the 
Mittelstaedt et al.  (2003) findings; however, 
our evidence is consistent with the findings 

of Wolff and Pett (2000), Autio et al. (2000), 
and others.

With this paper,  our contribution to the 
literature is an additional set of results 
showing that all firms, even very small 
firms, are capable of exporting.  With this 
finding, we help dispel some of the 
inconsistencies regarding the relationship 
between exporting and firm size reported in 
the literature. We have not conclusively 
resolved the empirical inconsistencies in the 
relationship between firm size and exporting, 
but we do provide another piece of evidence 
that moves us in that direction. Like Olson 
and Gough (2001), we conclude that future 
studies would be more useful if researchers 
pursue the performance implications of 
exporting by very small firms, rather than 
pursue more correlation studies of the sort 
we have presented in this study.  

Mittelstaedt et al. (2003) also offered 
suggestions to policy makers based upon 
their conclusions about firm size and export 
activity. They argued that policy makers 
should focus on fostering domestic growth 
strategies rather than exporting growth 
strategies for micro firms, given their result 
that micro firms are too small to effectively 
export.  Given our inability to support their 
research finding, we conclude that this 
advice may be misguided to the extent that it 
is based upon their empirical finding.  

Large firms usually start as small firms and 
grow over time. Rather than growing in a 
consistent and predictable fashion, small 
firms follow many different paths toward 
growth. Furthermore,  export activity is not 
neatly described in a simple 1-2-3 fashion. 
Early research accepted the stages model of 
internationalization (Johanson and Vahlne, 
1977), which argued that small firms 
gradually began exporting and escalated 
their efforts as they grew and gained 
experience. Bilkey (1978) and others 
essentially argued that exporting is a process 
of development. However,  more recent 
r e s e a r c h q u e s t i o n s t h i s p e r s p e c t i v e . 
McDougall,  Shane,  and Oviatt (1994) and 
Oviatt and McDougall (1995) argued that 
some ventures are created with the intent to 
sell internationally. Autio, Sapienza, and

(2003) label this the “born-global” trend, 
whereby new ventures are launched with 
cross-border business activities in mind. 
Given our findings that micro firms can and 
do achieve export success, we argue that if 
policy makers continue to assist micro firms 
with their exporting efforts, then these firms 
may grow to become large firms.

Our results have a practical message for 
business owners and business assistance 
professionals. Our results imply that business 
owners should not be dissuaded from 
exporting simply because their firm is very 
small.  We find no evidence of a minimum 
size below which exporting is necessarily a 
losing proposition for firms.  What we find is 
that the smallest firms are capable of 
exporting, even if fewer micro irms export 
than do larger firms. Our results have a 
similar message for business assistance 
professionals. Given the ability of micro 
firms to export and the absence of a 
minimum size threshold for exporting ability, 
business assistance professionals should not 
hesitate to recommend or support micro firm 
exporting, on general principle. A micro 
firms’ exporting success will depend on the 
firm’s particular market and on the skill and 
strategy of the business strategist,  but not on 
the number of employees.
