Subnational economic freedom and performance in the United States and Canada.
Bennett, Daniel L.
During his illustrious career spanning more than half a century,
Richard Vedder has tirelessly advocated for limited government and free
enterprise. Much of his scholarship has focused on examining how fiscal
and labor market policies consistent with the principles of economic
freedom are associated with economic and social benefits such as
stronger economic performance (Vedder 1981, 1990), lower unemployment
(Vedder and Gallaway 1996, 1997), and poverty alleviation (Vedder and
Gallaway 2002). Vedder has also examined the impact of government policy
on income inequality (Vedder 2006; Vedder and Gallaway 1986, 1999;
Vedder, Gallaway, and Sollars 1988), an area that he and I have
collaborated to study (Bennett and Vedder 2013, 2015). Thus,
Vedder's scholarship has contributed to our understanding of the
impact that economic freedom exerts on economic outcomes.
Vedder's research has primarily examined the effects of
individual policies such as the structure of taxation and barriers in
the labor market, but a mounting body of academic research links
aggregate measures of economic freedom to a variety of positive
economic, political, and social outcomes. Hall and Lawson (2014) and
Hall, Stansel, and Tarabar (2016) provide recent surveys of this
literature. This article builds on my previous work with Vedder and
contributes to the growing body of research on the effects of economic
freedom by examining the relationship between subnational economic
freedom and various measures of economic performance for a panel of U.S.
states and Canadian provinces over the period 1980-2010.
Existing theory and empirical evidence suggest that economic
freedom is positively associated with economic development and labor
market outcomes, which the evidence presented here further corroborates,
but the relationship between economic freedom and inequality is not well
understood. It is important to examine how economic freedom affects
inequality because income inequality has been heralded as the
"defining challenge of our time" by influential public figures
and economists. Free-market capitalism is often blamed for rising
inequality, and the prescribed solution is typically freedom-reducing
government interventions. Pope Francis (2013: 48), for instance,
describes market capitalism as a system of exclusion and inequality that
is "unjust at its roots." Paul Krugman (2013) points to U.S.
financial deregulation and entitlement reform as factors in driving
higher U.S. income disparities. President Barack Obama has repeatedly
expressed a desire to raise the federal minimum wage and increase the
progressivity of the income tax structure as means to stem the tide of
rising inequality. Thomas Piketty (2014: 1) argues that without
corrective political intervention, capitalist economies inevitably
produce rates of return on capital that exceed the growth rates of
income and output, a process that "automatically generates
arbitrary and unsustainable inequalities."
While free-market capitalism is heralded as the villainous
perpetrator of inequality, existing theory and evidence on the
relationship between economic freedom and inequality is largely
inconclusive (Bennett and Nikolaev 2015b). By necessity, institutional
and policy reforms intended to reduce inequality through government
intervention reduce economic freedom, potentially undermining the other
positive effects associated with economic freedom such as economic
development and improved employment opportunities, both of which enhance
economic well-being. The results presented here suggest that subnational
economic freedom is associated with higher levels of income per capita,
lower rates of unemployment, and higher income inequality across
subnational economies in the United States and Canada.
Methodology and Data
This article utilizes panel data from the 50 U.S. states and 10
Canadian provinces over the period 1980-2010 to estimate (lie partial
effects of subnational economic freedom on measures of macroeconomic
performance, including income per capita, the unemployment rate, and
relative income inequality. It does so using the fixed effects
specifications given by equation (1):
(1) [PERFORM.sub.rt] = [[alpha].sub.0] + [[alpha].sub.1]
[EF.sub.rt] + [X.sub.r,t] [beta]' + [[delta].sub.r] +
[[epsilon].sub.r,t],
where [PERFORM.sub.rt], [X.sub.rt] and [[delta].sub.r] represent
economic performance, economic freedom, a vector of control variables,
and a time-invariant state/province unobserved effect, respectively, for
state/province r in period t. (1) It is the first study on subnational
economic freedom and economic performance that I am aware of that pools
subnational data for these two North American countries. Because it does
so, the number of variables available to control for is limited because
of data availability and comparability.
Economic Freedom Data
Subnational economic freedom measures for the U.S. states and
Canadian provinces are from the Fraser Institute's Economic Freedom
of North America (EFNA) annual report (Stansel and McMahon 2013). The
EFNA composite index is comprised of three area indices: size of
government (EFNA1); distortionary taxation and takings (EFNA2); and
labor market freedom (EFNA3). (2) The data are available annually over
the period 1980-2010. The data used in this study reflect a five-year
average within two years of each period ending in zero and five to
minimize short-run fluctuations associated with business cycles.
Although the EFNA provides both all-government and subnational
government measures, this article utilizes the all-government EFNA data
only because it is assumed that incentives created or destroyed by
policy interventions are invariant to the level of government
instituting policy.
Economic Performance Data
Three measures of economic performance are utilized in this study.
First, gross income Gini coefficients are used as the measure of
relative income inequality. The Gini coefficient was chosen primarily
because of data availability but also because it is widely used in
empirical studies. The Gini coefficient is a measure of relative
inequality that ranges from 0 (perfect equality) to 1 (perfect
inequality). The Gini coefficient data for the United States come from
Galbraith and Hale (2008), who estimate family gross income inequality
measures annually using between-industry pay inequality data for each
state over the period 1978-2004. (3) Although the data are available
annually, quinquennial data are utilized in this article. Each
quinquennial observation reflects the five-year (+/-2 years of periods
ending in 0 and 5) Gini value over the period 1980-2005. (4) These data
are supplemented with the five-year average gross household income Gini
values over the period 2008-12 to extend the panel to 2010. The latter
data are from the American Community Survey five-year estimates. (5)
Gross family income Gini measures for the Canadian provinces are
from the Income Statistics Division of Statistics Canada and are
available annually over the period 1980-2011. As with the U.S. measures,
a five-year average for the period +/- 2 years of each quinquennial
period are used. The resulting panel of data includes quinquennial
measures for each of die 50 U.S. states and 10 Canadian provinces
spanning the period 1980-2010 and are referred to in the results as
GINI.
Next is the natural log of real income per capita, in constant 2011
U.S. dollars (LRGDPL). Nominal state-level GDP data and population data
for the United States are from the Census Bureau. Canadian
province-level nominal income and population data are from Statistics
Canada. (6) Third is the unemployment rate, or the number of unemployed
persons as a share of the total labor force (UNEMPLOY). These data are
from Statistics Canada and the Statistical Abstract of the United
States.
Data for Control Variables
Because this article pools subnational data for the United States
and Canada, the selection of control variables is limited by data that
is relatively comparable across die two countries. Several variables are
controlled for that potentially influence economic performance,
including the adult four-year college attainment rate (COLLEGE), the
share of the labor force employed in the manufacturing sector (MEG), the
dependency ratio (DEP2LAB), the female share of the population (FEMALE),
and the natural log of population density (LPOPDEN). (7) The source for
the Canadian data is Statistics Canada. Wifli the exception of the MFG
data, which is from the Bureau of Economic Analysis, all of the
state-level data are from the U.S. Census Bureau. Table 1 provides
summary statistics for all of the variables used.
Economic Freedom and Income Per Capita
Institutions and policies consistent with economic freedom promote
competition, incentivize investment, and encourage entrepreneurism,
providing an efficient economic environment for growth and prosperity.
Although much of the empirical literature has focused on the positive
relationship between economic freedom and economic growth (De Haan,
Lundstrom, and Sturm 2006; Doucouliagos 2005; Faria and Montesinos
2009), a number of studies also provide evidence that economic freedom
is a key determinant of income per capita across countries (Bennett et
al. 2015; Cebula and Clark 2014; Cebula, Clark, and Mixon 2013; Easton
and Walker 1997; Gwartney, Holcombe, and Lawson 2004) and subnational
economies (Ashby, Bueno, and Martinez 2013; Basher and Lagerlof 2008;
Wiseman and Young 2013).
Table 2 provides additional empirical evidence that subnational
economic freedom is positively related to income per capita in North
America by reporting the fixed effects estimates of equation (1) using
LRGDPL as the measure of economic performance. Column 1 reports the
results using the composite EFNA index. Columns 2, 3, and 4 report
results using each of the three economic freedom areas: size of
government (EFNA1), distortionary taxation (EFNA2), and market freedom
(EFNA3). Column 5 includes all three area measures simultaneously.
With one exception, all of the economic freedom variables enter
positively and statistically significant at the 1 percent level
throughout Table 2. Because the log of income per capita is used, the
coefficients can be interpreted as semi-elasticities, but this does not
allow comparison of the magnitude of the partial effects of the
independent variables. Among the freedom variables, EFNA and EFNA3 have
the most economically significant partial correlation with the level of
development, as a standard deviation increase in overall economic
freedom and labor market freedom are both associated with a two-thirds
standard deviation increase in LRGDPL. (8) Meanwhile, standard deviation
increases in EFNA1 and EFNA2 are associated with an approximately half
and third standard deviation increase in income per capita,
respectively. In column 5, EFNA1 and EFNA3 both enter positively and are
statistically significant at the 1 percent level, while EFNA2 is not
statistically significant. In this specification, standard deviation
increases in the size of government and labor market freedom areas are
associated with an approximately one-third and half standard deviation
increase in income per capita, respectively.
Among the control variables, COLLEGE is positive and statistically
significant at 10 percent or better in all but one specification, while
MFG, DEP2LAB, and FEMALE are all negative and statistically significant
in most specifications. The specifications in Table 2 jointly explain 69
to 76 percent of the variation in income per capita.
Economic Freedom and Unemployment
Economic freedom has also been linked to positive labor market
outcomes. Studies by Heller and Stephenson (2014) and Garrett and Rhine
(2011) find that state-level economic freedom is associated with lower
unemployment and greater employment growth, respectively, while Feldmann
(2007) and Stansel (2013) find country-level and U.S. metro area
economic freedom to be associated with lower unemployment, respectively.
Hall et al. (2013) find that state-level economic freedom is positively
associated with entrepreneurial startups, which create new jobs for the
economy.
Table 3 provides additional empirical evidence that economic
freedom exerts a positive impact on labor market outcomes by reporting
the fixed effects estimates of equation (1) using the unemployment rate
as the measure of economic performance. As with Table 2, the economic
freedom variables enter one at a time in columns 1 to 4, while column 5
controls simultaneously for all three area measures.
All of the economic freedom variables enter negatively and
statistically significant at the 1 percent level when controlled for
individually. Economically, EFNA3 has the strongest correlation among
the freedom variables, as a standard deviation increase in labor market
freedom is associated with a 1.34 standard deviation decline in the
unemployment rate. The specification that uses EFNA3 jointly explains 53
percent of the variation in the unemployment rate. The composite
economic freedom index also exhibits an economically strong correlation,
as a standard deviation increase in EFNA is associated with a 0.93
standard deviation decrease in the unemployment rate.
Meanwhile, standard deviation increases in EFNA1 and EFNA2 are
associated with approximately half a standard deviation drop in the
unemployment rate. In column 5, EFNA1 and EFNA3 both enter negatively
and significantly significant at the 10 percent level or better. A
standard deviation increase in the size of government area is associated
with one-fifth standard deviation decline in UNEMPLOY, while a standard
deviation increase in labor market freedom is associated with a nearly
three-fifths standard deviation decline in the unemployment rate, all
else equal. EFNA2 is not statistically significant.
Among the control variables, COLLEGE is negative and LPOPDEN
positive when statistically significant at 10 percent or better. MFG and
DEP2LAB are both statistically significant in more than half of the
specifications, but the sign of their coefficient is inconsistent.
FEMALE is never statistically significant. The specifications in Table 3
jointly explain 18 to 54 percent of the variation in the unemployment
rate. The specifications that account for labor market freedom explain
much more of the variation in the unemployment rate than those that do
not.
Economic Freedom and Income Inequality
Much less is known about the relationship between economic freedom
and inequality. Economic theory does not provide clear guidance on the
anticipated qualitative relationship between economic freedom and income
inequality. This is largely attributable to the fact that economic
freedom is a complex concept that is affected by a number of
institutions and policies that may exert a heterogeneous impact on the
distribution of income.
Using a static two-agent framework, Berggren (1999) attempts to
show that economic freedom impacts inequality through a variety of
institutions and policies, but concludes that, with the exception of
government redistribution, which reduces both economic freedom and
inequality, the impact of economic freedom on inequality through its
various channels is theoretically ambiguous. Berggren's theoretical
result that government redistribution reduces inequality depends,
however, on two simplifying assumptions that may not hold in practice.
First, it assumes redistribution from high to low income
individuals. The rent-seeking literature suggests that income is often
redistributed in practice to middle- or high-income groups, resulting in
a positive or ambiguous effect on inequality (Olson 1982; Vedder and
Gallaway 1986). Second, it assumes that changes in fiscal policy do not
affect economic performance, which is contrary to the so-called
equity-efficiency hypothesis (Okun 1975; Vedder 2006; Vedder and
Gallaway 1999). If redistribution negatively affects economic
performance, it is possible that lower income persons are
disproportionately impacted such that measured inequality does not
change or rises if the relative loss of market income is not offset by
income transfers. Vedder, Gallaway, and Sollars (1988) and Acemoglu et
al. (2013) discuss additional theoretical reasons why redistribution may
not reduce inequality. Even the conclusion that government
redistribution reduces inequality is not theoretically generalizable,
although Clark and Lawson (2008) and Scully (2002) find empirical
evidence that progressive tax and redistribution policies are associated
with less inequality.
Bergh and Nilsson (2010) offer further theoretical insights on how
the five main areas of economic freedom are expected to impact
inequality, (9) suggesting that sound monetary policy is associated with
less inequality, while limited government and private property rights
are associated with more inequality. However, their empirical results
concerning the relationships between these three areas of economic
freedom and inequality are statistically insignificant. Easterly (2007)
argues that one channel through which extreme inequality is perpetuated
is through weak private property rights and rule of law, an argument
further developed and supported with empirical evidence by Bennett and
Nikolaev (2015a).
Bergh and Nilsson (2010) suggest that standard international trade
theory predicts that freedom to trade internationally is associated with
more and less inequality in economically developed and undeveloped
nations, respectively. Their empirical findings, which are based on a
sample of predominantly middle- and high-income countries, suggest that
international trade freedom is positively associated with inequality.
Berggren (1999) finds a negative relationship between trade openness and
inequality. Bergh and Nilsson are agnostic on tire anticipated
relationship between the regulatory environment and inequality, but find
a positive empirical relationship. Blythe, Hopkin, and Werfel (2012) and
Hopldn and Blythe (2012) argue that there is a parabolic relationship
between regulatory freedom and income inequality, and provide empirical
evidence supporting their hypothesis. (10)
Given that the relationship between economic freedom and inequality
is theoretically ambiguous, several studies have examined tire
relationship between the two variables empirically, although fire
results have been mixed. Berggren (1999), Chirk and Lawson (2008), and
Scully (2002) find that country-level economic freedom is associated
with less income inequality, while Bergh and Nilsson (2010) find a
positive relationship between the two variables. Carter (2006) provides
evidence of a U-shaped relationship between fire economic freedom and
inequality across a set of developed nations. Bennett and Nikolaev
(2015b) find that the inconsistent results from cross-country analyses
are attributable to a number of factors such as the econometric
specification, measure of inequality, sample of countries, and/or time
period used, suggesting that none of the empirical cross-country results
from the literature are robust.
The above-referenced studies have all examined the relationship
between economic freedom and inequality across countries. Several
studies have also examined the relationship between subnational economic
freedom, as measured by die Frasier Institute's EFNA index, and
inequality across die 50 U.S. states. Each of these studies has used a
different econometric approach, but the results have been more
consistent than those of die cross-country studies, in general pointing
toward a negative relationship between economic freedom and inequality.
As discussed above, the EFNA index only accounts for heterogeneity
among states in the size of government, distortionaiy taxation, and
labor market policies (Stansel and McMahon 2013). National institutions
measured by the Economic Freedom of the World index, such as the
regulatory environment, monetary policy, international trade policy, and
private property rights, are relatively homogenous among states. These
macro-level institutions may nonetheless influence the distribution of
income at the subnational level such that results from state-level
analyses are not directly comparable to those from country-level
analyses because the margins at which institutions are operating at the
subnational and national level differ. Nonetheless, the findings of
subnational studies do provide additional evidence to help enhance our
understanding of the relationship between economic freedom and
inequality.
Using income quintile ratios as their measure of inequality, Ashby
and Sobel (2008) find that EFNA in 1980 and changes in EFNA over the
1980-2003 period are both associated with less income inequality in the
latter period. (11) They also find that lower minimum wage levels and
lower tax burdens are the best policies for reducing inequality. Using
panel data over the period 1979-2004, Bennett and Vedder (2013) find
that increases in EFNA are associated with lower levels of income
inequality, as measured by the Gini coefficient. They also provide
empirical evidence of an inverted U-shaped relationship between EFNA and
inequality, opposite Carter's (2006) findings of a U-shaped
cross-national economic freedom-inequality curve. (12)
Aspergis, Dincer, and Payne (2014: 74) analyze the relationship
between EFNA and state-level income inequality using time-series
techniques, finding that economic freedom has a long-run negative impact
on inequality, but indicate that Granger causality is bidirectional.
Regarding the latter result, they suggest that it is "possible for
a state to get caught in a vicious circle of high income inequality and
heavy redistribution" given that "high income inequality may
cause states to implement redistributive policies causing economic
freedom to decline. As economic freedom declines, income inequality
rises even more." (13) Although they do not explicitly consider the
impact of EFNA on relative inequality, Compton, Giedeman, and Hoover
(2014) find that increases in EFNA exert a positive and significant
impact on the growth rates of mean household income for the top four
quintiles, and a positive but insignificant impact on the bottom income
quintile.
Next, additional empirical evidence on the relationship between
subnational economic freedom and income inequality is presented. Table 4
reports fixed effects estimates of equation (1), where GINI is the
measure of economic performance. Among the economic freedom variables,
EFNA, EFNA1, and EFNA3 are statistically significant at the 5 percent
level or better, and each enters positively. The 0.65 coefficient
estimate for EFNA suggests that a standard deviation increase in
economic freedom is associated with an approximately quarter standard
deviation increase in GINI, all else equal. The coefficient estimate of
0.38 for EFNA1 suggests that a standard deviation in the size of
government area is associated with less than a fifth standard deviation
increase in GINI, while the coefficient estimate of 0.853 for EFNA3
suggests that a standard deviation increase in labor market freedom is
associated with less than a half standard deviation increase in GINI.
As with Tables 2 and 3, column 5 of Table 4 controls simultaneously
for the potential impact of EFNA1, EFNA2, and EFNA3 on inequality. EFNA2
has a coefficient of -0.39 and is statistically significant at the 1
percent level, suggesting that a standard deviation increase in freedom
from discriminatory taxation is associated with a 0.15 standard
deviation decrease in GINI. EFNA3 has a coefficient of 1.04 and is
statistically significant at the 1 percent level, suggesting that a
standard deviation increase in labor market freedom is associated with
an approximately half standard deviation increase in GINI. It is
interesting to note that the partial effects of EFNA2 and EFNA3 are both
economically and statistically stronger than the effects when each
variable entered individually. EFNA1 remains positive but is not
statistically significant in column 5.
Conclusion
This article builds on previous collaborative work with Richard
Vedder and examines how subnational economic freedom impacts economic
performance in North America. Specifically, it uses fixed effects
regressions to estimate the partial effects of various economic freedom
measures on income per capita, the unemployment rate, and relative
income inequality across the 50 U.S. states and 10 Canadian provinces.
It is the first study that I am aware of that pools data for the 50 U.S.
states and 10 Canadian provinces to further account for heterogeneity in
economic freedom and its potential impact on subnational economic
performance in North America.
The results largely corroborate existing evidence that economic
freedom is associated with higher levels of income per capita and lower
rates of unemployment. However, they also suggest that economic freedom
is associated with modestly more income inequality, a result that is
somewhat at odds with the small body of literature that has in general
found a negative relationship between subnational economic freedom and
income inequality in the United States (Aspergis, Dincer, and Payne
2014; Ashby and Sobel 2008; Bennett and Vedder 2013). This seeming
contradiction is unsurprising given the ambiguity of theory concerning
the relationship between the two variables and the inconclusiveness of
cross-country empirical work (Bennett and Nikolaev 2015b). One possible
explanation for the differing qualitative result is that the current
study pools data for tire United States and Canadian provinces. There is
greater variance in inequality and less variance in economic freedom
among tire states than the provinces.
The economic freedom of North America index is also decomposed to
examine how its individual areas affect economic performance. When
controlled for individually, all three areas are statistically
associated with higher levels of income per capita and lower rates of
unemployment. Controlling for all three measures simultaneously, both
the limited government and labor market freedom areas are statistically
associated with more income per capita, but only labor market freedom is
statistically associated with lower unemployment rates. Both the limited
government and labor market freedom areas are statistically associated
with higher income inequality when controlled for individually, but the
distortionary taxation and labor market freedom areas are statistically
associated with less inequality in the specification that accounts for
all three areas in the same regression.
While the results obtained in this article provide some insight for
economic policymakers, they are preliminary and should be interpreted
with caution for several reasons. First are the potential problems of
omitted variables and multicollinearity, which would bias the
coefficients and inflate the standard errors. As with all empirical
studies, the choice of control variables is limited by data
availability, particularly given that the current study pools data for
the United States and Canadian provinces. The independent variables
included in the study are among those routinely included in empirical
analyses of economic performance, and they jointly explain a significant
amount of the variation in the three measures of economic performance.
Any potential bias attributable to omitted variables is therefore
relatively small. The risk of multicollinearity is minimized by
excluding the alternative measures of economic performance, which are
fairly well correlated, as independent variables.
Next is the potential for reverse causality if one or more of the
independent variables is endogenous. Aspergis, Dincer, and Payne (2014)
provide evidence of bidirectional causality between economic freedom and
inequality across the U.S. states, and Murphy (2015) suggests the
inequality may hamper economic freedom. While it is recognized that
endogeneity may be an issue with the empirical specifications employed
here, it is beyond the scope of this article to attempt to establish
causality econometrically. That task, however, would be a fruitful area
for future research. Disentangling the potential direct and indirect
effects of economic freedom on the various measures of economic
performance is also a good avenue for future research.

(1) In some of the specifications used in this study, the Hausman
test suggests that a random effects estimator in a specification
including a dummy variable equal to 1 for Canadian provinces is
efficient, but in most specifications, the test suggests that the random
effects estimator is inconsistent. Because the fixed effects estimates
are always consistent and the results are qualitatively similar when
using a random effects estimator that includes a Canadian dummy
variable, only the fixed effects results are reported.
(2) For the interested reader, Alberta, Delaware, Texas, Nevada,
and Wyoming are the five most economically free subnational economies in
the most recent period. Prince Edward Island, Quebec, Nova Scotia, New
Brunswick, and Manitoba are the five least economically free subnational
economies in the most recent period.
(3) The data are available annually since 1969, but the subnational
economic freedom data are only available since 1980, so the earlier data
are not used in the current analysis.
(4) As an illustration, the observation for 2000 is the average
over the period 1998-2002.
(5) The 2010 observations are adjusted using a regression
technique. The Galbraith and Hale (2008) five-year average Gini measures
are regressed on household gross income Gini coefficients from the
decennial censuses over the period 1980-2000 and a set of fixed
time-effects for 1980, 1990, 2000, and 2010. The [R.sup.2] value from
the OLS estimates is 0.898. The coefficient estimates are then used to
predict the 2010 values.
(6) Nominal state-level income figures before 1997 pertain to SIC
industrial classifications, while post-1997 figures reflect NAICS
classifications. An average of the SIC and NAICS estimates is used for
1997. Population figures are only available annually after 2000, and in
census years before then. Intercensal populations were interpolated
using compound growth rates between the 1980-90 and 1990-2000 censuses.
State-level income per capita figures are converted to real 2011 figures
using the CPI-U. Province-level nominal income figures are available
annually over the period 1984-2010. Observations for 1980-83 are
extrapolated using provincial-level average annual growth rate over the
period 1985-89. The nominal income per capita figures are converted to
current U.S. dollars using purchasing power parity factors from the
World Bank International Comparison Program database. The current U.S.
dollar-denominated provincial figures are then adjusted to constant 2011
figures using the CPI-U.
(7) DEP2LAB is defined as the ratio of the number persons under age
15 and above age 65 to the number of persons between ages 15-64.
(8) Standardized coefficients are reported in the text for
comparability of the magnitudes of the partial effects of the
independent variables. Standardized coefficients ([bar.[beta]]) are
computed as follows: ([bar.[beta]]) = [beta] ([s.sub.EF]/[s.sub.perf]),
where [beta] and [s.sub.EF] denote the partial effect and standard
deviation of the economic freedom variable, and [s.sub.perf] represents
that standard deviation of the economic performance measure.
(9) The Fraser Institute's Economic Freedom of the World index
includes five main areas of economic freedom: (1) size of government;
(2) legal institutions and property rights; (3) sound money; (4)
international trade freedom; and (5) freedom from regulation of
business, credit, and labor markets (Gwartney, Lawson, and Hall 2013).
(10) Regulation from freedom is used as a proxy for economic
efficiency, and the audiors argue that low and high levels of efficiency
are associated with high levels of inequality, but intermediate levels
of efficiency are associated with low levels of efficiency.
(11) Carter (2006) criticized Berggren (1999) for including both
the level and change in economic freedom as regressors in the
latter's inequality model, suggesting that the results could be
interpreted as a distributed lag model such that the short- and long-run
effects of economic freedom on inequality are negative and positive,
respectively. A similar argument could be made about the results of
Ashby and Sobel (2008), although the point estimates suggest that both
the short-and long-run effects of EFNA on inequality are negative.
(12) The measures of national and subnational economic freedom
differ substantially, providing one possible explanation for these
conflicting results.
(13) Murphy (2015) argues that high levels of inequality may lead
policymakers to intervene in the market to reduce inequality, reducing
economic freedom.
