This article examines whether the use of impact fees and special assessments
affect the level of capital spending and two major own source revenues of
local capital spending (taxes and long-term debt) by analyzing a panel of
695 American cities with populations over 20,000 during the time period
of 1980–2000. Since impact fees and special assessments are heavily used
in a growing community and because it covers less than half the costs of new
development, the findings demonstrate that the private financing of public
infrastructure (impact fees and special assessments) increases the level of
local capital spending. It also leads to an increase in the level of long-term
debt use. Although it provides partial tax relief, it is not a strong substitute
for taxes. Thus, impact fees and special assessments are not a substitute for
local capital spending. It is rather a supplemental revenue source to fund local
capital infrastructure.

1. Introduction
In the wake of the taxpayer revolts and tax and expenditure limitation
(TEL) movements that have swept the nation since the late 1970s, a grow-
ing number of localities in many states have used impact fees and special
assessments to help pay for the existing, new, or expanded infrastructure
needed to serve communities. The impact fee is a one-time fee designed
to pay for the increased demand for public services generated by a new
development. Impact fees for different facilities are currently used in local
governments in twenty-eight states (Duncan Associates 2007), and it is
likely that more states will follow suit (Clarke and Evans 1999; Nelson and
Moody 2003; Jeong 2006; Duncan Associates 2007). Similarly, special
assessments have been frequently used as a tool to finance urban develop-
ment and redevelopment in many special assessment districts and localities.
Given that the areas served by the new facilities are required to pay the cost
of needed improvements, special assessments are similar in their function
and economic effects to fiscal impact fees (Yinger 1998; Bierhanzl and
Downing 2004).
With the growing use of impact fees in local governments over time,
many have conjectured that the impact fee may influence the level of local
capital spending and other local revenue sources that are used to fund local
infrastructure (e.g., property taxes, total taxes, long-term debt proceeds).
Conceptually, since both impact fees and special assessments are designed
to transfer a portion of the capital costs for the new and expanded infrastruc-
ture from the public (taxpayers) to the private sector (developers and
builders), these revenue sources could be considered alternative means of
private financing of the portion of the public infrastructure, especially if the
impact fees do not affect the rate of development in the community (Yinger
1998; Clarke and Evans 1999; Burge, Nelson, and Matthews 2007). Since
the infusion of revenue from impact fees could affect other revenue streams
used to finance local capital spending (e.g., property taxes, total taxes, and
long-term debt proceeds), the use of impact fees may substitute for other
local revenue sources that were used to fund local infrastructure. However,
if the impact fees cover only a portion of infrastructure costs for the new
development and lead to an increased rate of development in the commu-
nity, then impact fees may increase the level of local capital spending rather
than substituting for other revenue streams typically used to fund local
infrastructure. In this case, impact fees may serve as a supplemental revenue
source for local capital spending. In practice, impact fees usually finance
614 Public Finance Review

less than half of the costs for new development, leaving local tax payers to
cover the remaining portion of the costs of new development in the form of
higher taxes or higher long-term debt use (Burge, Nelson, and Matthews
2007; Duncan Associates 2007). Furthermore, since the use of impact fees
could affect the path (rate) of development and/or the desired level of public
services in the community, this would further complicate the effects of
impact fees on the level of local capital spending and the streams of other
revenue sources that are used to pay for local capital spending (Burge,
Nelson, and Matthews 2007).
This article examines the effect of impact fees and special assessments
on the level of local capital spending and two major own-source revenues
of local capital spending (taxes and long-term debt) in a panel of 695 Amer-
ican cities with populations over 20,000 during the time period of 1980–
2000. Given that no studies have empirically examined the relationship
between impact fees (and special assessments) and capital spending and
major sources of revenue of local capital spending (taxes and long-term
debt) by using a longitudinal national data set, this study provides important
insights into our understanding on the nature of the impact fees and special
assessments.
The next section discusses analytical framework and literature review.
This is followed by section 3, which describes data, research methodology,
and variables used in the study. Research findings are then presented and
discussed. The final section concludes the article.
2. Analytical Framework and Literature
2.1. Analytical Framework and Research Hypotheses
Traditionally, the proceeds of long-term debt, current taxes, and intergo-
vernmental grants coming from federal and state governments have been
three major revenue sources to fund local capital projects (expenditure),
although the relative importance and composition of these revenue sources
for capital spending has varied among jurisdictions, projects, and time.
However, with the taxpayer revolts and voter-imposed TEL movements
sweeping the nation, many local governments have also relied on nontax
revenue sources such as charges and miscellaneous revenues (e.g., impact
fees and special assessments) to address growing needs of local capital
spending.

Since most jurisdictions prohibit using the proceeds of long-term debt to
finance current operating expenditures, almost all long-term debt proceeds
are used to fund capital improvements. Thus, the proceeds of long-term debt
have been one of the most important revenue sources for most local capital
improvement projects (Leonard 2004). Two basic types of long-term debt
include general obligation (GO) bonds and revenue debt. GO bonds are
secured by the full faith and credit of the taxing powers of the issuing gov-
ernment, thus legally obligating the local governments to levy taxes on all
assessable property within its jurisdiction at whatever level is necessary to
meet the debt service payments on the bonds. The repayment of the princi-
pal and interests of the GO debt usually comes from an increase in local
property tax rates or other taxes (e.g., the sales tax). In general, this unlim-
ited GO debt is an appropriate financing vehicle for capital projects that
benefit the entire community (e.g., public schools). However, since local
governments must pass referenda to use GO debt, and the principal and
interests of GO debt is usually serviced by raising the property tax millage
rate or other local taxes (e.g., sales tax), the tax payer revolts and the TELs
that swept the country in late 1970s and 1980s has resulted in less use of GO
debt vis-à-vis revenue debt, as demonstrated in the analysis of 695 panel
sample cities in figure 1.
Unlike GO debt, the repayment of the principal and interests of revenue
debt (bonds) is secured by the revenues collected from a specific project
being financed. Since the use of revenue bonds does not require the passage

Revenue Debts of the Sample Cities
616 Public Finance Review
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
of referenda, many local governments have turned to revenue bonds and
other forms of financing (charges and fees) schemes since the late 1970s
to fund the growing demands of local infrastructure arising from population
growth and local economic development purposes (Leonard 2004).
Other than the property taxes, other tax revenues (such as local sales tax)
are also used to finance long-term capital spending. Since the 1980s, some
states like Georgia, South Carolina, and Wisconsin have permitted their
localities to use local sales taxes to pay for local capital spending (Jung
2002). Nontax revenue sources such as charges and fees and miscellaneous
revenues (e.g., impact fees and special assessments) have also emerged as
important sources of financing for growth and economic development since
the 1970s. These revenue sources have been used to bypass political, legal,
and administrative limitations imposed on the use of taxes (especially prop-
erty tax) and long-term debt and to realize the benefit-received principle of
infrastructure financing (Downing and Frank 1983; Mullins and Joyce
1996; Bierhanzl and Downing 2004).
Nontax revenue sources frequently used to fund growth and develop-
ment include development fees, fiscal impact fees, special assessments, and
tax increment financing (TIF). Development fees are user charges that
cover public infrastructure within the new development. These fees are
imposed directly on the developer of the new property. Although similar
to development fees, fiscal impact fees are often levied to pay for additions
to public infrastructure. The costs of these additions, such as an expansion
to a water treatment plant, will be shared between the current residents and
the new developments. Similar to both development fees and fiscal impact
fees, special assessments are based on the benefits-received principle. Spe-
cial assessments serve to make sure that residents pay for additional ser-
vices, such as sidewalks or street lights, which are added to their area.
While impact fees are only used for new capital investment purposes, spe-
cial assessments could be used not only for new development but also for
operations and maintenance, and the collection is also often recurring.
TIF provides an additional method for financing new development. Basi-
cally, TIF allows for the subsidization of new infrastructure costs within the
TIF district by diverting some of the property tax collection within the TIF
away from general revenue directly to infrastructure improvements. Through
TIF, property taxes in new developments and surrounding areas are set up by
local governments to mimic user charges. As a result of the improvements to
the public sector infrastructure, tax assessments are structured around the
benefits that accumulate for property owners (Bierhanzl and Downing
2004). Although there are similarities between development fees, fiscal
Jung et al. / Longitudinal Effects of Impact Fees 617
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
impact fees, special assessments, and TIF, it should be noted that develop-
ment fees, fiscal impact fees, and special assessments are loosely defined
as taxation while the TIF is kind of a subsidy to pay for the infrastructure.
While the use of impact fees and special assessments has increased over
time, there is little empirical evidence as to how impact fees and special
assessments affect the level of local capital spending and other fiscal revenues
streams used to fund local capital spending. While one may predict that impact
fees and special assessments simply substitute for other revenues sources for
local capital expenditure like taxes and long-term debt, this would not be the
case if the use of impact fees and special assessments affects the path (rate) of
development and/or the desired level of public services in the community.
It should be noted that, depending on the nature and design of the impact
fees, the use of impact fees may slow down, speed up, or have no effect on
residential and other types of construction. Conceptually, the use of impact
fees and special assessments could result in one of three reactions in the
development path in the community, which will in turn affect the level of
capital spending and two major own-source revenues of local capital spend-
ing (Yinger 1998; Ihlanfeldt and Shaughnessy 2004; Burge, Nelson, and
Matthews 2007). First, if the impact fees and special assessments work as
direct excise taxes on construction, it may slow down the rate of develop-
ment in the community since the additional taxes increase the price of land,
which has a negative impact on the number of parcels of affordable and
available land for new development. Second, if the collection of impact fees
and special assessments provides offsetting benefits such as better quality
local infrastructure and increased housing prices, then the rate of develop-
ment in the community may remain constant. Third, if the use of impact
fees and special assessments brings more benefits than the costs of new
infrastructure financing, then the rate of development in the community
actually may increase. In this case, the provision of infrastructure financed
by impact fees and special assessments would facilitate further develop-
ment, which may cause further population growth and business attraction.
Numerous factors are involved in determining the rate of community
development, which makes the prediction of the influence of impact fees
and special assessments on the level of capital spending and own-source
revenues of capital spending quite complicated. Other factors being equal,
potential consequences of the imposition of impact fees and special assess-
ment on the level of capital spending and its components (taxes and long-
term debt) would be as follows.
Under the first scenario, where the imposition of impact fees and special
assessments results in a slowdown of development in the community, the use
618 Public Finance Review
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
of impact fees and special assessments may result in a decrease in the level of
local capital spending since there will be less development and this will lower
the overall need for local capital spending. As the level of local capital spend-
ing decreases, it may also lower the level of taxes and long-term debt use.
Under the second scenario, the imposition of impact fees and special
assessment results in a constant rate of development in the community. If the
level of service provision remains the same, then the levying of impact fees
and special assessments may have no effect on the level of local capital
spending since the collection of impact fees will now partially finance infra-
structure costs that were once fully financed with taxes and debt proceeds. In
this case, impact fees and special assessments may act as a dollar-for-dollar
substitute for taxes, since the bulk of the principal and interest of GO debt is
repaid with increases in property tax and other taxes. If impact fees and spe-
cial assessments provide a dollar-for-dollar tax reduction, then they may also
lower pressure for the further use of long-term (GO) debt issuance.
Under the third scenario, where the provision of infrastructure financed by
impact fees and special assessments facilitates further development, the
impact fees will result in additional local capital spending needs due to an
increasing rate of development in the community. Given that impact fees usu-
ally cover less than half the cost of infrastructure for new development, the
collection of impact fees and special assessments may increase the level of
local capital spending, since the local government must spend additional
money to cover remaining infrastructure costs for new development under
this scenario. With this increased capital spending, the impact fees may result
in higher taxes and additional long-term debt use. In this case, the impact fees
may or may not provide tax relief. If there is any tax relief, it may be only
partial tax relief. In this case, the impact fees may increase the level of newly
issued debt (or outstanding long-term debt) since local governments should
rely more on debt issue to fund the costs of capital expansion for further
development while providing some tax relief. It seems highly likely that this
scenario provides the best fit for predicting the influence of the impact fees
and special assessments on the level of capital spending and two major
own-source revenues of local capital spending or taxes and long-term debt.
2.2. Research Hypotheses
Based on the above analytical framework, we propose that the provision
of infrastructure financed with impact fees and special assessments would
facilitate further development, which will result in additional local capital
Jung et al. / Longitudinal Effects of Impact Fees 619
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
infrastructure spending needs. The collection of impact fees may or may not
provide partial tax relief, but since it does increase the rate of development,
it would also increase the level of long-term debt use for funding further
development in the community. Thus, we come up with the following
hypotheses. Hypothesis 1: The use of impact fees and special assessments increases the level
of local capital spending.
Hypothesis 2: The use of impact fees and special assessments provides partial tax
relief.
Hypothesis 3: The use of impact fees and special assessments leads to an increase
in the level of long-term debt.
2.3. Literature
Reflecting growing interest in the use and effects of impact fees and spe-
cial assessments, a sizable amount of research has addressed different
aspects of impact fees and special assessments. Although the economic
effects of special assessments are similar to those of impact fees, most of
the research focuses on impact fees in part due to their increasing use as rev-
enue and its relative newness compared to special assessment in local
finance. The 2007 National Impact Fee Survey by Duncan Associates
describes the recent use and pattern of impact fees in the nation (Duncan
Associates 2007). Compared to its 2003 survey, the survey reports growth
in the number of states and localities using impact fees, as well as the pur-
poses for which they are used. The survey also reports that impact fees are
widely used in the South and West, particularly Washington, Oregon, Cali-
fornia, Arizona, Colorado, and Florida. Impact fees are less frequently used
in the Northeast and Midwest.
Several articles report factors affecting the adoption of impact fees
(Frank and Downing 1988; Clarke and Evans 1999; Lawhon 2003; Jeong
2006). These works find that enabling state legislation, community growth,
fiscal health and stress, form of government, and administrative capacity
influence the likelihood of local adoption of impact fees. In general, impact
fees and special assessments are used in states where the state government
permits its local government to use the revenue. In these states, growing
communities and fiscally stressed cities are more likely to adopt impact
fees. Likewise, reformed cites (council-manager cities) and cities that have
higher administrative capacity are more likely to collect impact fees.
A growing body of literature also addresses the effects of impact fees on
several aspects of community growth and development. These include the
620 Public Finance Review
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
effects of impact fees on housing price and housing production and
economic development and job growths. Although Burge, Nelson, and
Matthews (2007) summarize major findings on the various topics, these
issues are still controversial and complex. This section briefly introduces
the main issues of these topics.
With respect to the effect of impact fees on housing price, the ‘‘tradi-
tional view’’ and the ‘‘new view’’ of the property tax make different predic-
tions concerning the short-run impact. The ‘‘traditional view’’ considers
impact fees to be an excise tax on the production of housing. This perspec-
tive assumes that the imposition of impact fees leads to an increase in hous-
ing price, which lowers profits for developers’ on the quantity of new
homes built (Snyder, Stegman, and Moreau 1986; Downing and McCaleb
1987; Huffman et al. 1988; Delaney and Smith 1989a, 1989b; Singell and
Lillydahl 1990; Altshuler and Gomez-Ibanez 1993).
Yinger (1998) and the following works by Nelson and Moody (2003),
Ihlanfeldt and Shaughnessy (2004), and Burge and Ihlanfeldt (2006a) chal-
lenge this view. The ‘‘new view’’ perceives impact fees not as an excise tax
but as benefit principle–based user fees and charges; that is, although the
impact fee imposes costs for developers in the permitting process, it also
brings several offsetting positive effects just as do other forms of benefit
principle–based charges and fees. This perspective says that impact fees
reflect the cost of providing the valued facilities needed to serve new devel-
opment, and thus they may offset property taxes that would otherwise have
been assessed. Put differently, improved infrastructure in the newly devel-
oped area, made possible by the imposition of impact fees, will eventually
increase the property value of the home in the area. This will also lower
future property tax rates in the area (Burge, Nelson, and Matthews 2007).
This mechanism needs a bit more explanation since it explains how
impact fees could affect the level of property taxes. If one assumes that a
local government relies almost exclusively on property taxes to finance new
facilities, and that there is no change in the quality of the facilities accom-
panying the move from property taxes to impact fees, then this view sug-
gests that prices for both new and existing homes will go up. However,
the increase in prices should equal the capitalized value of the property tax
savings that homeowners expect from the reduction in the tax rate. In this
case, the property tax rate declines because the imposition of the impact
fees shifts the costs of new infrastructure from existing property owners
to developers. For example, Ihlanfeldt and Shaughnessy (2004) demon-
strate that a U.S.$1 impact fee collection resulted in about U.S.$1.20 prop-
erty tax relief in Dade County, Florida. Thus, if appropriately structured, the
Jung et al. / Longitudinal Effects of Impact Fees 621
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
use of impact fees and special assessments could transfer a portion of the
burden of infrastructure costs from the local government (taxpayers) to the
private sector (builders and developers) because builders and developers
help pay for the infrastructure that provides access, utilities, and other ame-
nities critical to a development’s success (Yinger 1998; Clarke and Evans
1999; Ihlanfeldt and Shaughnessy 2004).
Concerning the effects of impact fees on housing production, the main
question is whether the imposition of impact fees will affect the production
of new affordable housing (Brueckner 1997; Skidmore and Peddle 1998;
Mayer and Somerville 2000; Burge and Ihlanfeldt 2006a, 2006b). Critics,
who perceive impact fees as excise taxes, argue that impact fees may nega-
tively affect the amount of buildable land and housing, and thus, the number
of units of affordable housing will go down. However, the opposite view,
which perceives impact fees as fees or charges, proposes that the use of
impact fees for infrastructure enhancement may actually increase the supply
of buildable land in the community rather than stifling housing production.
Since the units of housing production are determined both by supply and
demand in the housing market, the effects of impact fees on residential con-
struction rates are more complicated than their effects on prices. To date,
few studies have directly investigated the effects of impact fees on housing,
and Burge, Nelson, and Matthews (2007) concludes that the effects are
quite ambiguous.
With respect to the effects of impact fees on economic development, the
‘‘traditional view’’ of impact fees suggests that the imposition of impact
fees may stifle economic development and job growth. However, the ‘‘new
view’’ sees that better infrastructure provision with the impact fees collec-
tion may further promote economic development and job growth. Empirical
findings demonstrate that impact fees spent on infrastructure tend to stimu-
late economic development and job growth (Nelson and Moody 2003;
Jeong and Feiock 2006).
While a sizable amount of research has addressed various effects of
impact fees, to date only Clark and Evans (1999) have analyzed whether the
collection of impact fees results in increased local capital spending. They
analyzed the relationship between the use of impact fees and the level of
capital spending, by examining eighty-five American cities for a single
cross-section year, and they found that the use of impact fees lowered the
level of capital spending. Although the study is one of the first to look at
the relations between impact fees and capital spending, Clark and Evans
(1999) did not control for other revenue sources that could affect the level
of capital spending (e.g., long-term debt, taxes, intergovernmental grants,
622 Public Finance Review
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
and charges). Likewise, they did not consider the influence of impact fees
on the path of development in the community. Moreover, their study did not
examine how impact fees affect the major revenue sources for capital
spending (taxes and long-term debt). Since Clark and Evans (1999) exam-
ined only a single year data set for a limited sample, it is difficult to general-
ize from their study. Given that local capital investments are largely
nonrecurrent and require many years to be replaced (or repaid), it is neces-
sary to examine a large national sample over a long period of time to get a
better understanding of the effects of impact fees on the level of capital
expenditure and major revenue sources of capital expenditure. This study
fills the research void by analyzing the effects of impact fees and special
assessments on the level of capital spending and two major own-source rev-
enues of capital spending (taxes and long-term debt) for a panel of 605
American cities over a twenty-one-year period.
3. Research Methods
3.1. Data
This study used an annual data set of a panel of 695 American cities with
populations over 20,000 for the entire study period (1980–2000). In 1980,
there were more than 19,000 American cities, of which about 1,300 cities
reported having a population of over 20,000. Since we are interested in
building a panel sample, we selected cities whose demographic, socioeco-
nomic, financial, and other variables are available for the study period. This
reduced the size of the panel sample to 695 cities. It would have been pre-
ferable to examine more cities, especially cities with populations under
20,000 to better understand longitudinal local fiscal behavior. However,
given the practical difficulty of collecting relevant variables for a panel data
set over twenty-one years, this study limited the sample to cities with popu-
lations of over 20,000, especially because of the practical difficulty of col-
lecting demographic, socioeconomic, fiscal, institutional, and other
variables for smaller cities. It should be noted that many small cities did not
consecutively submit their financial and other data set information to the
Census Bureau during the study period.
With respect to impact fees and special assessments, the Census Bureau
did not report impact fees and special assessments separately in its annual
Local Finance series. Rather, impact fees and special assessments are
lumped together and reported as ‘‘special assessments’’ under the
Jung et al. / Longitudinal Effects of Impact Fees 623
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
‘‘miscellaneous revenue’’ section. If impact fees and special assessments
were separately reported, a separate estimation of the effect of each revenue
source would be possible. However, the aggregation of the impact fees and
special assessments makes it almost impossible to analyze the separate
effects of each. It should be noted that most local governments in most
states do not report impact fees and special assessments separately either.
Rather, they report it under ‘‘other revenues’’ or ‘‘miscellaneous revenue.’’
For example, the State of Georgia reports the impact fees and special assess-
ments of its local governments under ‘‘other revenues’’ in its annual Report
of Local Government Finance.
The Census Bureau defines special assessments as ‘‘compulsory contribu-
tions and reimbursements from owners of property who benefit from specific
public improvements; and impact fees to fund extension of water, sewer,
roads, and other infrastructure facilities in new developments.’’ Furthermore,
the Bureau goes on to elaborate that ‘‘these contributions and reimbursements
are designed to defray all or part of the costs of such improvements, either
directly or through payment of principal and interest on debt issued to finance
them’’ (www.census.gov/govs/www.class_ch7_misc.html). It should be
noted that special assessments cover a range of upgrades from general street
improvements such as sidewalks to utility improvements such as waterlines.
In general, these special assessments are assigned based on the assumed ben-
efits that would result from the improvements.
\The annual finance data set for the study was collected from the Census
Bureau’s Local Finance. Demographic and socioeconomic variables, such as
size of population, income, and age, were collected from the Census Bureau’s
decennial Population and Housing files and County and City Data Book. Forms
of municipal governments were collected from the International City/County
Management Association’s (ICMA) The Municipal Year Book series.
3.2. Research Model and Variables
The local finance literature indicates that the level of capital expenditure,
total taxes, and long-term debt are affected by demographic, socioeco-
nomic, fiscal, and institutional factors (Chicone and Walzer 1986; Poterba
1995; Jung 2001). Since we estimate the influence of impact fees and spe-
cial assessments on the level of capital expenditure, total taxes, and long-
term debt, we use the same sets of control variables to maintain consistency
and facilitate the comparison of estimates among models. Thus, the primary
model we use in the study can be written as
624 Public Finance Review
at CA STATE UNIV SAN BERNARDINO on March 8, 2012pfr.sagepub.comDownloaded from
Level of capital expenditure, total taxes, long-term debt ¼ f (demo- graphic, socioeconomic, fiscal, institutional factors).
The three dependent variables are capital expenditure, total taxes, and
long-term debt. These, and all other fiscal variables, are expressed in per
capita values to mitigate possible heterogeneity problems among different
localities.
The primary independent variable is lagged per capita impact fees and
special assessment (Impact feest – 1). Since the current level of impact fees
collection could either increase or decrease current levels of taxes or long-
term debt, and vice versa, we use a lagged value of impact fees and special
assessments to alleviate potential reverse causality problems with the
dependent variables in the study.
To capture the demographic factors, we use three variables: population
size, population density, and percentage of population under eighteen. If
annual population statistics were available for the panel sample, we could
use the population growth rate to estimate the effects of population growth
on dependent variables. However, the annual population is not available,
and so we use the natural log of population size to indirectly capture the
effects of population growth on the dependent variables. Population density
is expressed as population per square mile. The percentage of population
under eighteen is frequently used to capture local service demands. Other
things being equal, if the percentage of population below eighteen
increases, this would place more pressure on local governments to increase
capital spending to provide additional infrastructure (e.g., public schools).
To capture socioeconomic factors in local finance, we use a per capita
income variable. Other things being equal, higher income leads to a higher
level of, or more varied, local services. To reflect the impact of institutional
factors on local finance, we use the form of municipal government. Profes-
sional cities under a council-manager form of governance are known to be
more active in developing and using new revenue sources for long-term
growth and economic development compared to the mayor-council or other
forms of cities (Mullins and Joyce 1996; Jeong 2006). For these reasons,
council-manager cities are more likely to use impact fees and special assess-
ments than other cities. Professional city management has also been shown
to affect the level of taxes, capital expenditures, and long-term debt
(Chicone and Walzer 1986; Poterba 1995; Jung 2001). To capture the like-
lihood of such innovation, we use a council-manager dummy variable,
coded 1 for council-manager form cities and 0 for others.
Since it is necessary to control for other internal and external sources of
revenue such as charges and fees (total charges), intergovernmental grants,
Jung et al. / Longitudinal Effects of Impact Fees 625

taxes, and long-term debt that could also affect the level of dependent vari-
ables, we use lagged values of these fiscal controls to alleviate the possibil-
ity of reverse causality and endogeneity problems (Wooldrige 2006). To
control for inflation, all the fiscal variables are converted into constant dol-
lars using the 1980 gross domestic product (GDP) implicit price deflator for
state and local government purchases as a base.
Table 1 presents variable definitions, sources of data set, and summary
statistics. As table 2 indicates, 181 cities collected some amount of impact
fees and special assessments consecutively during the entire study period,
while fifty-one cities never used this source.
3.3. Statistical Models
Since there are variations in the level of capital spending, taxes, and
long-term debt among sample cities over time, we use a fixed effects model,
which controls unit-specific fixed effects in the estimation (Wooldrige
2002). Likewise, since the year could also affect the dependent variables,
control for time effects must be considered. Hausman tests and joint signif-
icance tests of time effects for all the proposed models in the study show
that the sample data have both unit-specific and time-specific effects, and
we address these issues by using a two-way fixed effects model in the esti-
mation (Wooldrige 2002; Baltagi 2008).
4. Findings
Table 3 presents the results of the two-way fixed effects regression
model estimating the effects of impact fees and special assessments on the
level of local capital spending, property and total taxes, and long-term debt.
As pointed out above, since the primary own-source revenue for local cap-
ital spending comes from local taxes (such as property and sales taxes) and
the proceeds of long-term debt (both GO and revenue debt), an analysis of
the effect of impact fees and special assessments on taxes and long-term
debt provides a better understanding of how each component affects the
level of local capital spending. Since the property tax is the primary tax rev-
enue for most local governments as well as the primary revenue source to
repay the principal and interests of GO debt, we present separate effects
of the variable.

The first column of table 3 presents estimates for the capital expenditure
model; the second column (the property tax model) and the third column
(the total taxes model) show the estimates for the property tax and for total
taxes, respectively. The fourth and fifth columns present estimates for out-
standing long-term debt and for long-term debt issued, respectively. To get
detailed effects of impact fees and special assessments on different types of
debt (GO and revenue) and expenditures (current and total expenditures),
we also present the results of these estimates in table 4.
The positive and statistically significant coefficient (0.29) of the impact
fees variable (Impact feest – 1) in the capital expenditure model in table 3
indicates that one dollar of impact fees and special assessments leads to
an increase of about twenty-nine cents in total capital spending. However,
a positive but insignificant coefficient of the impact fees and special assess-
ments (0.17) variable in the final column (the total expenditure model) in
table 4 indicates that impact fees and special assessments do not increase
the level of total government expenditure. Similarly, a negative and insig-
nificant coefficient of the impact fees and special assessments variable in
the fifth column of table 4 indicates that impact fees and special assess-
ments do not increase the level of current expenditure. Given that total
expenditure is composed of current operating plus capital expenditure, these
findings indicate that impact fees and special assessments do not lead to an
increase in the level of current operating or total expenditure, but they do
significantly increase the level of capital spending. Additionally, impact
fees and special assessments do not lead to a dollar-for-dollar increase in
capital spending since portions of the impact fees and special assessments
are used to provide tax relief or other revenue relief.
An examination of the relative magnitude of major revenue sources on
capital spending in the capital expenditure model in column 1 of table 3 pro-
vides an interesting finding. While a one dollar increase in impact fees and
special assessments revenue increases the level of local capital spending
about 29 cents, an increase of one dollar in federal and state grants brings
about a twenty-two-cent increase in capital spending. This is followed by total
taxes with a four cent increase and long-term debt with a two cent increase.
These results suggest that impact fees and special assessments could be an
effective and powerful tool to increase the level of local capital spending.
To estimate the effects of impact fees and special assessments on the
magnitude of tax relief, we present both a property tax and a total taxes
model for the reasons explained above. A negative and statistically signif-
icant coefficient (–.06) of the impact fees and special assessments variable
in the property tax model in the second column of table 3 indicates that a

one dollar impact fees and special assessment revenue collection provides
about 6 cents of property tax relief. Likewise, the negative coefficient of
impact fees and special assessments in the total taxes model (the third col-
umn of table 3) indicates that a one dollar impact fees and special assess-
ment collection provides about twelve cents total tax relief. These
findings suggest that impact fees and special assessments provide a small
amount of tax relief for both property and total taxes, which is far from
being a dollar-for-dollar tax relief as reported in Ihlanfeldt and Shaughnessy
(2004). Our finding confirms the new view’s perspective that the imposition
of impact fees shifts part of the property tax (and the total tax) burden from
existing property owners to builders and developers.
Since the influence of impact fees and special assessments on long-term
debt could be analyzed by examining both the outstanding and newly
issued debt, we present both the outstanding long-term debt and newly
issued long-term debt models in table 3. We are more interested in the
effects of impact fees and special assessments on additional debt use, so
we place more emphasis on the long-term debt issued model. However,
as several factors affect the amount, types, and timing of long-term debt
issue, we also examine both the outstanding (unpaid accumulated debt) and
newly issued debt to understand the influence of impact fees on the use of
long-term debt. In addition, since local governments could use both GO and
revenue debt to fund additional infrastructure costs, we present the break-
down of total outstanding and newly issued debt in table 4 to get a better
understanding of the relative influence of the impact fees on the use of these
debt instruments.
The long-term debt outstanding model and the long-term debt issued
model of columns 4 and 5 of table 3 present the effects of impact fees and
special assessments on the level of outstanding long-term debt and newly
issued long-term debt, respectively. Although the R 2
is very low, the posi-
tive and significant coefficient of the impact fees and special assessments
variable (1.23) in the long-term debt issued model indicates that a one dollar
increase in impact fees and special assessments leads to an increase of
U.S.$1.23 in new long-term debt issue. This suggests that the use of impact
fees will bring more development into the community, some of which is
financed with newly issued long-term debt. When the total newly issued
debt is broken down into the GO and revenue debt, the collection of
impact fees and special assessments brings about a fifty-six-cent increase
in GO debt while bringing about a sixty-seven-cent increase in revenue
debt, as seen in the third (GO debt issued model) and the fourth (revenue

debt issued model) columns of the table 4. This confirms the trend that
revenue debt is more heavily used to fund additional infrastructure
(Leonard 2004).
Unlike the newly issued debt, impact fees and special assessments in the
outstanding long-term debt model are not significant, as seen in the fourth
column of table 3. However, when the total outstanding debt is broken into
GO debt outstanding (first column) and revenue debt outstanding (second
column), as seen in the table 4, impact fees and special assessments signif-
icantly increase the level of outstanding GO debt, which they do not do for
revenue debt even in this model. The above empirical findings confirm all
three hypotheses proposed earlier.
Taken together, the above findings show that impact fees lead to an
increase in local capital spending. Thus, the use of private financing of pub-
lic infrastructure via impact fees and special assessments did not substitute
for municipal capital spending. While impact fees and special assessments
provide a small amount of tax relief, they do not provide a dollar-for-dollar
property or total tax relief. This suggests that impact fees and special assess-
ments are not strong substitutes for local taxes. Moreover, since impact fees
and special assessments lead to an increase in the level of long-term debt
issue, they do not remove the pressure to use long-term debt. Since one dol-
lar in impact fees and special assessments results in an increase of 29 cents
in capital spending and since the magnitude of long-term debt use
(U.S.$1.23) far outweighs that of total tax relief (12 cents), it could be inter-
preted that impact fees and special assessments are more of a supplement to
capital spending.
The implications of the empirical findings in the study suggest that sce-
nario 3 (impact fees speed up development in the community) is operative
in the panel sample cities; that is, it is highly likely that impact fees and spe-
cial assessments are heavily used in growing cities and that the use of
impact fees and special assessments promote further development. Since
impact fees and special assessments usually cover less than half of costs
of new development, their use results in more local capital spending, which
is financed with long-term debt issue and current taxes. In the process, the
use of private financing of public infrastructure does not provide a large
enough revenue source for the local government to offset or substitute for
municipal capital expenditure. This means that local governments must
make additional capital expenditures to subsidize the infrastructure financ-
ing for the new development and redevelopment in the growing areas. Thus,
the findings indicate that impact fees and special assessments do not

significantly substitute for local infrastructure spending. Rather, they serve
as supplemental revenue to local capital spending.
5. Conclusion
Our estimation results suggest that the use of impact fees and special
assessments accelerates the rate of development in the community. Since
typical impact fees cover less than half the costs of new development in
growing communities, the remainder is covered with increased debt issue
or taxes. These findings show that a one dollar collection of impact fees
and special assessments led to an increase in capital spending of about
twenty-nine cents. Thus, the use of private financing of public infrastructure
did not substitute for municipal capital spending. Although the impact fees
and special assessment provided a partial tax relief of about twelve cents,
they were not powerful tax relief measures. Our study also shows that
impact fees and special assessments led to an increase in the level of
long-term debt issue, rather than removing the pressure for the use of new
long-term debt. Thus, we conclude that impact fees and special assessments
supplement local capital spending rather than serving as a substitute for
local capital spending.
Although this study improved our understanding of the effects of impact
fees and special assessments on the level of local capital spending and
major revenues sources of local capital spending, our study has several lim-
itations. First, since most local governments do not report these impact fees
and special assessments separately to the Bureau of Census, we were not
able to analyze a separate effect of impact fees and special assessments.
Since a separate source of revenue for impact fees and special assessments
might be found only in the comprehensive annual financial reports of indi-
vidual cities, a future study could build on this study’s data set by using
individual cities’ financial reports. Second, in part due to the difficulty of
collecting necessary socioeconomic variables, this study could not analyze
cities with population below 20,000. To get a thorough understanding on
the topic, future studies could include cities with population below
20,000 in the analysis. Third, in general, the explanatory power of the mod-
els estimated is fairly low in part due to the employment of limited variables
within the national sample. Future studies could analyze single-state sam-
ples using more detailed and relevant variables that could affect the depen-
dent variables. Even so, our study is one of the first national analyses that
empirically examines whether the use of impact fees and special

assessments affects the level of local capital spending and major revenue
sources of local capital spending.
