Economic freedom and net business formation.
Campbell, Noel D. ; Rogers, Tammy M.
Economic freedom indexes, especially the Fraser Institute/Cato
Institute Economic Freedom of the World (EFW) index and the Heritage
Foundation/Wall Street Journal Index of Economic Freedom, are becoming
increasingly important as researchers seek to explore the link between
economic freedom and prosperity. The consistent finding is that nations
with more economic freedom--as indicated by security of property rights,
free trade, limited government, low marginal tax rates, and so
forth--enjoy higher per capita incomes and general living conditions compared with countries that are less free. (1)
In a less aggregated study, Karabegovic et al. (2003) find that
differences in economic freedom across U.S. states and Canadian
provinces are significantly and positively related to differences in the
level and growth of economic activity across states and provinces.
Various researchers have used the Economic Freedom of North America (EFNA) index, published by the Fraser Institute (Karabegovic, McMahon,
and Mitchell 2005), to address questions of income differentials between
states, income growth, and entrepreneurship. (2) Scholars have also used
the EFNA index to study migration. Ashby (2007), not surprisingly, finds
that people tend to move from less free to more free areas.
In this article, we apply the EFNA index to the question of
business formation, similar to Kreft (2003) and Kreft and Sobel (2005).
Specifically, we ask whether the governmental, judicial, and social
activities observed in the index are significantly related to net
business formation among the states. We posit that greater economic
freedom results in higher income levels for state residents because such
freedom increases the opportunities to pursue entrepreneurial
activities. Thus, such freedom should be positively and significantly
correlated to net business formation, as measured by the net change in
the number of businesses as a percentage of total businesses by state.
Consistent with our expectations, we find that there is a strong
positive relationship between economic freedom in a state and net
business formation, after controlling for state population, income,
median age, federal intergovernmental revenue, minority percentage in
the population, and commercial lending.
Our results are qualitatively consistent with the arguments
advanced by Sobel, Clark, and Lee (2007), Clark and Lee (2006), and
Kreft and Sobel (2005): When economies become politicized, effort is
channeled away from wealth creation and into securing protection from
market forces. Consistent with our empirical results, states with less
economic freedom--and therefore more intrusive government--experience a
lower rate of business formation because the benefits of private,
for-profit entrepreneurial activity decline relative to other forms of
economic and political activity.
Entrepreneurship, Economic Freedom, and Economic Performance
Promoting entrepreneurship has emerged as a significant policy tool
for regional economic growth and job creation (Friar and Meyer 2003;
Laukkanen 2000; Rosa, Scott, and Klandt 1996). Indeed, Maillat (1998)
argues that economic development policy has shifted to promoting
endogenous economic growth via entrepreneurship and away from
competitive growth via attracting businesses from elsewhere.
The relevant policy question becomes how best to promote
entrepreneurship. One answer repeatedly championed in the literature is
to increase economic freedom, conceptualized as follows:
Policies are consistent with economic freedom when they provide
an infrastructure for voluntary exchange, and protect individuals
and their property from aggressors seeking to use violence,
coercion, and fraud to seize things that do not belong to them.
However, economic freedom also requires governments to refrain
from actions
that interfere with personal choice, voluntary exchange, and the
freedom to enter and compete in labor and product markets
[Gwartney and Lawson 2002: 5].
There is now strong evidence that economic freedom promotes
economic prosperity and growth. (3)
Most of the work using economic freedom indexes emphasizes
differences in economic freedom across countries. Those indexes
emphasize that differences in institutions largely create the observed
differences in economic freedom. It is interesting to consider whether
similar differences in institutions exist among the U.S. states. Under a
federalist system each state has its own constitution, and there are
significant differences in economic rules and regulations. For example,
the costs of doing business in Colorado and West Virginia are markedly
different.
Kreft and Sobel (2005: 604) forcefully state the argument that ties
together economic freedom, entrepreneurship, and growth:
Underlying economic freedoms generate growth primarily because
they promote underlying entrepreneurial activity.... In areas with
institutions providing secure property rights, a fair and balanced
judicial system, contract enforcement, and effective limits on
government's ability to transfer wealth through taxation and
regulation, creative individuals are more likely to engage in the
creation of new wealth through productive market entrepreneurship.
In areas without these institutions, creative individuals are more
likely to engage in attempts to capture transfers of existing
wealth through unproductive political entrepreneurship.
Neither the literature nor policymakers have consistently defined
either the differences or the overlap between entrepreneurship and
business formation. Kreft and Sobel (2005) follow the Bureau of Economic
Analysis and proxy entrepreneurial activity with the number of sole
proprietorships. Indeed, in popular parlance, entrepreneurship and
business formation are used nearly synonymously. Correspondingly, we
choose to focus on business creation and business destruction as a proxy
for entrepreneurship.
Economic Freedom of North America
We observe the EFNA index as a panel of all U.S. states from 1990
to 2001. Karabegovic et al. (2003) choose to group 10 variables--usually
expressed as ratios of gross state product (GSP)--into three categories:
size of government, takings and discriminatory taxation, and labor
market freedom. For size of government, the authors measured general
consumption expenditures by government as a percentage of GSP, transfers
and subsidies as a percentage of GSP, and Social Security expenditures
as a percentage of GSP. For takings and discriminatory taxation, the
authors measured total state government revenue as a percentage of GDP,
top marginal income tax rate and the income threshold at which it
applies, indirect tax revenue as a percentage of GSP, and sales taxes
collected as a percentage of GSP. They rate top personal income tax
rates by the income thresholds at which they apply, where higher
thresholds result in a better economic freedom score. For labor market
freedom, the authors measure minimum wage legislation, government
employment as a percentage of total state employment, and union density.
Karabegovic et al. (2003) construct a scale from 0 to 10 to
represent the underlying distribution of the 10 variables in the index,
with higher values indicating higher levels of economic freedom. Thus,
the EFNA index is a relative ranking of economic freedom across
jurisdictions and across time.
The Data and the Tests
We draw our data from a variety of sources. Economic freedom data
for the U.S. states are from Karabegovic, McMahon, and Mitchell (2005);
firm and employment data are from the Small Business Administration
Office of Advocacy; lending data are from the Federal Deposit Insurance
Corporation; and all other data are from the U.S. Bureau of the Census.
We construct a panel using the U.S. states as our cross-sectional
element, covering the years i990 through 2001 (see Table 1 for a
description of our variables and Table 2 for summary statistics).
Our dependent variable in each case is net new business formation
in the state as a percentage of total businesses in the state.
(1) [Business.sub.i] = (business [births.sub.i] - business
[deaths.sub.i])/total [businesses.sub.i] x 100.
We observe total net new businesses, net new businesses of 99 or
fewer employees, net new businesses of 500 or fewer employees, and net
new businesses of more than 500 employees. We focus on net business
formation--business births minus business deaths--rather than on
business formation or business collapse because net business formation
is a better indicator of business conditions in a state.
Conceptually, this measure accounts for new firms forming from the
resources of failing firms.
Though some of the literature focuses on sole proprietorships, we
choose to focus on new businesses regardless of organizational
structure. Wong, Ho, and Autio (2005) and Friar and Meyer (2003), among
others, demonstrate that new growth ventures stimulate economies, but
new ventures do not. In addition, new growth ventures tend to form
around an entrepreneurial team with significant industry experience
(Friar and Meyer 2003, Bygrave 1997, Timmons and Spinelli 2006). Many
small businesses may also be formed as Subchapter S corporations to
provide their owners with the limited liability benefits of the
corporate form while allowing for the preferential tax treatment of the
sole proprietorship. Counting only sole proprietorships therefore may
omit the most economically significant type of entrepreneurship.
Our model is an amalgam drawl from the economic freedom literature
and the firm formation literature, and is essentially a derivative of
the Solow (1956) growth model common in the literature on freedom
indexes. Similar to the Solow model, we include income and population (a
proxy for the labor force) as explanatory variables, and also include
capital investment (as measured by the volume of commercial and
industrial loans in a state). Those variables are similar to firm birth
and firm death models, such as Johnson and Parker (1994, 1996). We also
include the median age of each state's population, the combined
percentage of African Americans and Latinos in the state's
population, real federal intergovernmental revenues (FIGR) per capita,
and the dollar volume of all commercial and industrial loans by all
FDIC-insured institutions, by state by year.
In fitting models incorporating median age, one needs to address a
subset of questions regarding "lifestyle entrepreneurship"
versus "income entrepreneurship." One may expect the incidence
of lifestyle entrepreneurship to be higher among older populations, as
retirees begin second careers as entrepreneurs. Conversely, one may
expect income entrepreneurship--in which the entrepreneurial activity is
an individual's primary labor market activity, and is conducted
with the intent to earn income--to be higher among a younger population.
Entrepreneurship is commonly discussed as a viable method for minority
populations to improve their economic status. Accordingly, we include
each state's nonwhite percentage to test for minority
entrepreneurship.
We expect FIGR to act as an exogenous demand boost within a
state--that is, a boost in spending that will be met in part by business
start-ups. We assume that each state's taxpayers have paid their
federal taxes into a common pool of federal revenue. Taxes paid
represent purchasing power that has left the state. Somewhat
independently of taxes paid, revenues return from the common pool to the
state via FIGR, hence our treatment of FIGR as an exogenous increase in
purchasing power.
As an additional issue, researchers have investigated the direct
versus the indirect effects of economic freedom on economic outcomes
(Dawson 1998, 2006; Gwartney, Holcome, and Lawson 2004, 2006). For
example, suppose one argues that income growth depends on labor force
growth, capital growth, and economic freedom. It is very plausible that
capital formation is itself a function of economic freedom. The solution
is to regress capital growth on all of the other independent variables
from the original income growth equation and then use the residuals to
reestimate the equation. Comparison of the original income growth model
and the "residual" model may then shed light on the relative
strength of the direct versus indirect effects of economic freedom.
We follow this approach when considering economic freedom, income
per capita, and commercial and industrial loans. We argue that in
addition to the "total" or "direct" effect that
economic freedom has on creating economic opportunities and allowing
individuals to pursue those opportunities through entrepreneurship,
economic freedom will also have an "indirect" impact on labor
productivity (changes in income) and capital productivity (proxied by
our commercial and industrial loans variable).
We estimate models as a pool using ordinary least squares (OLS). In
addition, given our data set and research question, we estimate
"fixed effects" models fitting an intercept adjustment for
each state. The essential structure of a fixed effects model is that
variation across groups (such as across states) is captured in shifts of
the regression function, by calculating a separate adjustment to the
intercept for each group (state).
The Empirical Results
Our key results appear in Table 3. We estimate all models using
White's correction for heteroskedasticity. We estimate the first
two models using OLS and the second two models using the fixed effects
estimator. The R-squared statistics range from 0.30 to 0.47, all models
have very large F-statistics ranging from 30.66 to 40.42, and all
additional F-statistic testing the joint significance of the state fixed
effects are significant at the 99 percent level. This evidence supports
our choice of fixed effects estimation. In all cases our dependent
variable is "Total"--that is, the total net number of new
firms as a percentage of all firms in a state. We also observed this
variable broken down by the number of employees. However, a very strong,
positive correlation exists among Total, net new start-ups with fewer
than 100 employees, and net new start-ups with fewer than 500 employees.
Due to the high correlation, we chose to use Total exclusively. The
dissimilar variable is net new firms of more than 500 employees.
However, given the rarity of such large new start-ups, we chose not to
estimate models using that variable.
The coefficients on age are negative, relatively stable, and
significant across models. These results have intuitively appealing
explanations. Ceteris paribus, states with younger populations have more
economic activity, including new firm start-ups, supporting the
proposition that more firms are founded as "income producers"
rather than "lifestyle businesses." Somewhat surprisingly, the
coefficients on income and changes in income were generally
insignificant. The sole exception is a negative and significant
coefficient on income in the fixed effects model. Therefore, what
evidence we do find is indicative of "survivalist"
entrepreneurship--people turning to entrepreneurship to escape poor
incomes--rather than "gazelle" entrepreneurship, where new
businesses are formed to take advantage of the opportunities created by
a wealthy economy. However, this evidence is very weak. To an extent,
the results on income are determined by the relatively high correlation
between FIGR and income. Dropping FIGR from the model produces generally
negative and significant coefficients on income in the fixed effects
models.
The coefficient on minority percentage is uniformly negative and
significant, indicating that fewer new businesses form in states with
high nonwhite population percentages. Entrepreneurship has long been
understood to be a route to economic attainment frequently taken by
minorities, but our evidence indicates that this message has not
particularly penetrated. FIGR and changes in FIGR are insignificant in
all specifications.
The results on loan volume seem counterintuitive. Though always
small in effect, the volume of commercial lending is negatively related
to new business formation--that is, a greater volume of commercial and
industrial loans within a state is associated with the formation of
fewer businesses within a state. Though counterintuitive, the result is
not entirely unexpected. Johnson and Parker (1996) report inconsistent,
but possibly negative, results from the literature regarding home
equity, a proxy for loan availability.
The variable of main interest is "Freedom" (i.e.,
economic freedom). Consistent with expectations, its coefficient is
positive, stable, and highly significant across models. As measured by
the EFNA index, greater economic freedom in a state leads to more new
business formation as entrepreneurs take advantage of opportunities.
That result continues to hold even after controlling for other factors
expected to have an impact on new business formation.
We now turn to the question of whether the greatest impact of
economic freedom on new business formation is direct or indirect. We
hypothesize that the independent variables most likely to be a function
of economic freedom are income and commercial lending. Accordingly, we
implement the procedure suggested by Gwartney, Holcombe, and Lawson
(2004, 2006) and Dawson (2006). In separate equations we regress income
and loans on the remainder of the independent variables, and save the
residuals as new variables, "income-hat" and
"loans-hat." In the second step, we reestimate the original
model of net new firm formation, but substitute income-hat for income
and loans-hat for loans. Table 4 presents side-by-side comparisons of
our models. In all models, the results on freedom, income, and loans are
qualitatively and quantitatively unchanged. From this we conclude that
the primary impact of economic freedom on new business formation is
direct, rather than indirect through effects on income and commercial
lending. In other words, the primary impact of economic freedom on
entrepreneurial activity lies in permitting entrepreneurs to see and
exploit economic opportunities.
Turning to the question of the "economic" or
"practical" significance of economic freedom, we evaluate
model OLS 1 in Table 8 at the sample means. An increase in the median
age by one standard deviation increases the median age from 34.74 years
to 36.67 years, which results in a decrease of total net new businesses
by 0.40 percentage points, to 1.19 percent of the state's total
businesses. An increase in minority percent by one standard deviation
increases the minority percent from 18.02 to 30.31, which results in a
decrease of total net new businesses by 0.12 percentage points, to 1.47
percent of the state's total businesses. An increase in commercial
and industrial loans by one standard deviation increases the mean by
$33.7 million to $51.5 million, which results in a decrease of total net
new businesses by 0.15 percentage points, to 1.44 percent of the
state's total businesses.
Turning to Freedom, we observe that an increase in the EFNA index
by one standard deviation increases the mean from 6.909 to 7.65, which
results in an increase of total net new businesses by 0.34 percentage
points, to 1.94 percent of the state's total businesses. In
absolute value, this impact is more than twice the marginal effect of a
similar increase in commercial lending and nearly three times the
marginal effect of a similar increase in minority percentage. In
absolute value, Freedom's marginal impact is 85 percent of the
marginal impact of a similar change in median age.
Conclusion
Given Freedom's statistical significance, relatively large
marginal effects, and primacy of its direct effects--and the relative
political and social undesirability of using policy to reduce median age
and minority percentage--we conclude that the effects of increasing
economic freedom in a state trump any other effect we discovered.
Compared with the other variables we examined, pursuing public policies
consistent with increasing freedom will have a more direct and powerful
impact on new business formation than will policies aimed at
demographics or lending.
Our results are qualitatively consistent with the arguments
advanced by Sobel, Clark, and Lee (2007), Clark and Lee (2005), and
Kreft and Sobel (2005): When economies become overly politicized and
less free, effort is channeled away from wealth creation and into
securing protection from market forces. Therefore, consistent with our
empirical results, less free states experience a lower rate of business
formation as the benefits to market entrepreneurship fall relative to
nonmarket behavior.
Compared with the other variables we examined, pursuing public
policies consistent with increasing economic freedom will have a direct
and powerful impact on new business formation. Rather than succumb to
the understandable temptation to "fix the problem" through
government intervention, state governments should focus instead on
creating an environment that safeguards property rights and allows
entrepreneurs the freedom to flourish. A smaller, less active government
that leaves more income in consumers' and entrepreneurs'
pockets, disengages from income redistribution, and avoids a large
payroll will do more to promote prosperity than the conventional state
development model.
