U. S. Public Infrastructure and

Its Contribution to Private Sector Productivity

By Aklilu A. Zegeye*

Abstract: The study examines the impact of public infrastructure capital on the productivity of the

manufacturing sector for a sample of over 1500 counties and the 50 U. S. states using a translog production

function approach. The study also examines productivity convergence across states and across counties. The

county level data are chosen as a unit of analysis in order to minimize the impact of the macro-economy on the

estimates. The study finds a positive correlation between infrastructure and output at both the state and local

levels. The evidence also seems to suggest that the elasticity of public capital on private sector output rises

with the level of aggregation. The estimates further show that convergence is occurring faster at the state level

than at the county level which has a similar implication of increasing spillover with the level of aggregation.

However, the study finds that even though public infrastructure does have an impact on output and productivity

at both the state and county levels, its influence on productivity is small.

U. S. Public Infrastructure and Its

Contribution to Private Sector Productivity

The study examines the impact of public infrastructure capital on the productivity of the manufacturing sector for a sample

of over 1500 counties and the 50 U. S. states using a translog production function approach. The study also examines productivity

convergence across states and across counties. The county level data are chosen as a unit of analysis in order to minimize the impact

of the macro-economy on the estimates. The study finds a positive correlation between infrastructure and output at both the state and

local levels. The evidence also seems to suggest that the elasticity of public capital on private sector output rises with the level of

similar implication of increasing spillover with the level of aggregation. However, the study finds that even though public

infrastructure does have an impact on output and productivity at both the state and county levels, its influence on productivity is small.

Ι. INTRODUCTION

A number of studies have examined the relationship between public sector infrastructure

capital and its contribution to private sector productivity.1 There is little doubt that public sector

infrastructure affects private sector production by increasing aggregate demand and by

augmenting productivity and output.2

One important source of disagreement in the literature arises from choices in the level of

aggregation. By and large, the reported elasticities of infrastructure on output at different levels

of aggregation are mixed. The findings frequently imply under-investment in infrastructure, but

the evidence is far from firm and thus hardly conclusive. At the national and state levels, the

macro economic effects of any spending including infrastructure may dominate the positive

 

1 Using national, regional, metropolitan, state and industry level data, studies by Eberts (1986), Aschauer (1989),

Munnell (1990), Garcia Mila and McGuire(1992), Morrison and Schwartz (1992), and Nadiri and Mamuneas

(1994) have shown a significant contribution of public capital to private sector productivity. On the other hand,

using regional and state data, Hulten and Schwab (1993), Evans and Karras (1994), Holtz-Eakin (1994) find no

evidence that public capital growth leads to greater productivity growth. Hulten and Schwab (1984, 1993), Eisner

(1991), and Munnell (1990) did regional studies by breaking down states into four regions (northeast, north

central, south, and west) while Meira (1975) divided the 48 states into 9 US census regions. Eberts (1986), Deno

and Eberts (1989) using a translog production function, and Deno (1988) using a translog profit function estimated

the effects of some of the components of public sector capital stock on regional manufacturing output for 38

metropolitan areas, while Nadiri and Mamuneas (1991) estimated a cost function at an industry level using twelve

two digit US manufacturing industries. Deno and Eberts (1989) estimated for 28 SMSAs for the first half of the

1980s using 2SLS rather than OLS to avoid simultaneity bias that can arise between private income and public

investment. See Gramlich’s (1994) survey article for a range of estimates and some of the issues.

 See Tatom (1991) and Holtz-Eakin (1993b) who have examined a number of issues such as fixed effects, specification of

error structure, endogeneity bias, restrictions on the coefficients to satisfy constant returns to scale, and the effects of

aggregation.

externalities of spending on production. Specifically, public spending may increase aggregate

demand and provide stimulus to the economy. However, this result may not be unique to

infrastructure. In such cases, the resultant correlation between public spending and private sector

output may not be the result of the public good nature of public capital. Second, public sector

spending may be a normal good. That is, as income rises the demand for public infrastructure

increases so that the correlation between infrastructure and output may reflect the marginal

propensity to consume public goods rather than any productivity enhancing effects of

infrastructure.

This paper seeks to address these concerns by examining manufacturing production at

the county level. While state output has its own components that are not tied to the aggregate

economy, large states are clearly affected by national trends. In general, counties are the smallest

geographical areas for which significant amounts of data are available. Since output is less

correlated across counties than across states and regions, analysis of infrastructure at the more

disaggregated levels are more likely to measure the impact of infrastructure on output rather than

the marginal propensity to spend tax revenues on infrastructure.3

We will estimate fixed effect models to eliminate unobservable productivity differences such

as natural resource endowments and air and water quality as well as further test their differences

using more broadly defined regional categories (north, south, east and west) as dummy variables.

The study will also address the issue of productivity performance and productivity convergence

across U. S. counties.

Furthermore, to examine the possible existence of differences of productivity of

manufacturing due to the degree of urbanization, the study uses Beale's codes for U. S. counties

 At the county level, national influences are considerably muted and the correlation between county level growth and

national growth are much weaker.

(which divide counties into 10 demographic regions depending on the degree of urbanization and

nearness to a metro area) as dummy variables. 4

Because there are no comprehensive measures of private and public capital stock, to my

knowledge, available at the county level, this study will construct a measure of public and private

capital stocks based on the perpetual inventory technique. This approach improves on the use of

current capital outlays or adding up a short series of past capital expenditures. It further weakens

any correlation between infrastructure spending and aggregate stimulus.

In section 2, we begin by sketching the model which provides the basis for analysis,

discussing appropriate estimation techniques. The sources and description of data are discussed

in section 3, while section 4 presents the empirical results of these estimates and their effects on

productivity. In section 5, we discuss productivity performance and productivity convergence

across U. S. counties, while the final section is a summary.

ΙΙ. METHOD OF ANALYSIS

Aggregate production relates the gross state or county manufacturing output (Q) to four

inputs: private capital (K), workers (L), intermediate materials (M), public sector capital (G) and

the level of technology, and thus Q = F(L, M, K, G, t). A Translog production function in its

unrestricted form is:5

 See Butler (1990) for details of Beale’s code grouping. The coefficients of these variables will measure systematic effects

of amenities associated with congestion (versus open space). According to McGuckin and Peck (1992), the Beale codes

grouping (also known as rural-urban continuum codes) which is published by the Department of Agriculture is a much finer

residential grouping than the traditional census metropolitan and non-metropolitan classification.

5

 The production function is twice differentiable and is modified to include public sector infrastructure as an

"externality" factor. The production function is decreasing and convex in the three input quantities, but increasing

and concave in G. We assume changes in G result in costs of adjustments. See Guilkey et al (1983) for the

demonstarted superiority of the translog functional form over the alternate functional forms. Kaizuka (1965) is the

first to introduce public capital as one of the inputs, besides labor and capital, in a private production function.
5

A well behaved production (a factor demand) function must be homogeneous of degree one

(zero) in quantities. Symmetry (b b ) ij ji= and Hick's neutrality are imposed a priori in the

specification of (1). Depending on the specific model, constant returns to scale in either the

private or all inputs including public inputs is imposed. The corresponding income shares of labor

and capital are defined, respectively, as:

To account for state- and county-specific fixed effects, variables are entered in the translog

production function as deviations from their state- or county-specific means. For example, the

observation vectors for each county involve differences for each county’s value from the mean

which is generated using all the counties under study in that state.6

The production function and input shares depend not only on input quantities, output and

technological change, but also on public infrastructure capital. The spill-over effects of public

sector capital on cost and input shares are captured by the magnitudes and signs of the

The parameters in (3b) on public capital should be interpreted as a measure of the marginal

product of infrastructure on manufacturing. Because the model is estimated using the

manufacturing sector only, the total return (or social return) to aggregate production may well be

larger since it includes both the returns to manufacturing and nonmanufacturing establishments as

well as individuals.

7

The production model has three equations--the output equation and the labor and private

capital share equations (the share of intermediate input is generated as a residual). These

equations share some of the same parameters and are estimated jointly with the appropriate cross

restrictions using either the Zellner’s Iterative Seemingly Unrelated Regressions (ITSUR)

technique, iterated three stage least square method or iterated ordinary least squares method with

demographic and regional dummies. They are also estimated in a first difference and pooled

cross-section regression format.

The study also tests the appropriateness of the degree to which the estimated production

function satisfies the assumption of constant returns to scale (CRTS) in the private inputs

(i.e., S + S + S = 1

M K L

), or constant returns to scale in all the inputs including public

infrastructure (i.e., S + S + S + S = 1

M K L G

).

It is now common practice to estimate production functions using the dual rather than the primal

form.8 We have not chosen to do so because the dual relies heavily on the quality of the price data.

County level price deflators for output or intermediate inputs do not exist in our data and so we have had

to rely on state-level price data and county-level composition to estimate county level prices. As a result,

 

7

 The difference between the social benefits or the shadow price (ZG) and social user cost of public capital (PG) indicates

public capital investment opportunities. When marginal products exceed the price, additional investment is warranted.

Firms do not pay directly for public capital and thus the price (PG) is taken to be zero to the firm. For society at large,

however, the price (PG) is non-zero.

8

 See Griliches (1967), Nadiri (1970), Friedlander (1990) and Morrison and schwartz(1992) for a discussion of the dual

form and its advantages.
7

there is little variation in input prices at the county level. However, expenditure data are directly

observable for counties and so we believe that estimation of the primal rather than the dual is preferable.

In addition, state level price data limit information available to the translog functional form at the

county level. For example, since the state deflators for materials are being used as county deflators, the

translog interaction term estimates between materials and the other inputs for the counties could not have

revealed any additional information compared with the state estimates. Nevertheless, some county level

price and quantity data are available and so the translog form can maximize the use of information

compared to more restrictive forms such as Cobb-Douglas and CES.

ΙΙΙ. DATA CONSTRUCTION AND DESCRIPTION

We assemble data on the prices and quantities of outputs and inputs of workers, private

capital and intermediate materials for the states and 1514 counties from the quincennial Census of

Manufactures (CM) for aggregate manufacturing and corresponding public infrastructure capital

from the Census of Government (CG) publications for 1982, 1987 and 1992.9This data is part of

a research effort aimed at creating a complete set of state and county accounts for inputs and

outputs as well as the different types of public infrastructure at the two digit and aggregate

manufacturing levels. The purpose of these accounts is to allocate U. S. manufacturing growth

and productivity to its different sources at the state and local levels.

Every five years, both CG and CM programs under the Department of Commerce provide

comprehensive statistics on all units of government, their forms and activities, and all multi-unit

and single-unit manufacturing establishments production and input usage, using a nationally

consistent set of definitions and classification. Data from complete censuses are used because

annual surveys (for example, Annual Survey of Manufactures (ASM)) are designed to measure

activity by industry at the national level while census data can be used for county level analysis as

well.

 

9

 BEA, Census of Government, Census of Manufactures have not only been the source of our data, but Mr. Henry Wulf

(Census of Government) and Mr. Tim Dobbs (Bureau of Economic Analysis (BEA)) have been extremely helpful in

clarifying definitional and procedural issues concerning data collection of respective data sets.
8

The sample of states and 1514 counties is constrained by the availability of consistent private

capital stock estimates for the three census years. Although it would have been desirable to use a

four-, a three-, or even a two-digit manufacturing SIC as our frame of analysis, confidentiality

requirements by industry at the county level are quite severe and the remaining sample would not

have been representative. Moreover, there is no theoretical guidance for apportioning

infrastructure assets into the different sectors of the economy (e.g. agriculture, manufacturing,

etc.) let alone ferreting out the different responses of each industry within manufacturing to

expanded provision of infrastructure. Therefore, the analysis is limited to total manufacturing in

each state and county under study. State level aggregates were then adjusted to reflect BEA or

BLS estimates of the national totals. However, such data controls were not available for the

county level data since not all counties in each state were included in our sample.

ΙΙΙA. OUTPUT AND INTERMEDIATE INPUTS

We begin with state and county series for value of shipments in current dollars obtained

from CM as a measure of gross product. According to Norsworthy and Malmquist (1982), the

gross output specification puts less restrictions on the production function than does value-added.

As a production concept, value-added is appropriate only if there is perfect competition. The

implicit assumption for using a value-added specification is that capital and labor are separable

from their intermediate inputs and further precludes it from the growth accounting approach.

According to Basu and Fernald (1997), value-added does not, in general, capture the “net”

contribution of primary input and technology to output. Therefore, we use the gross state and

county product; consistent with gross output, capital and labor, and intermediate inputs are used.

The price deflator for manufacturing output for each state is calculated as a weighted

average of BLS national 2-digit output prices using state specific industry output share weights

for each year.10 Because county level output deflators are not available from any sources, these

 

10 Because a complete set of county output data are unavailable , county level weights cannot be constructed and used.
9

state output deflators are also used to deflate the county gross outputs. If the law of one price

within the states does not hold, county prices are changing relative to the respective state

deflators, or the composition of output within industries varies across counties, then state

manufacturing deflators will misstate real county output. However, these estimates improve upon

the national output deflators used in past studies.

The data for intermediate inputs include all purchased materials and fuels. The material

costs from Census data are much less than BEA’s intermediate input. Census attributes more of

total output to value-added while BEA allocates more to intermediates, which include purchased

business services. Accordingly, the material values from the Census have been adjusted to include

the actual dollar value of purchased business services from the BLS KLEMS MFP database.11

The BLS national total has been apportioned to each state and county in proportion to its share of

materials in the Census data. Consequently, the gross state product has been increased to account

for these changes.

The deflators for materials at the state level were calculated using double deflation of

gross output and value-added. That is, real gross output minus real value-added equals the real

value of materials. From this, the price of materials is the ratio of nominal to real materials. The

deflator used for value-added in each state is the ratio of nominal to real GSP from BEA’s Gross

State Product (GSP). Because county level materials deflators are not available from any sources,

these state deflators are also used to deflate the county intermediate inputs.

ΙΙΙB. LABOR

In general, labor input for each state and county is measured as a Tornqvist index of total

hours worked for production and non-production workers, while the hourly compensation for

production and non-production workers are used to form cost share weights. The CM contains

the hours paid and employment of production workers for establishments, but only employment of

 

11 See Gullickson (1992) for details.
10

non-production workers. Because hours paid are a more accurate measure of labor input than

employment, we develop estimates of hours worked for non-production workers. To convert the

employment of non-production workers to an estimate of hours worked, we multiply the number

of non-production workers by the average annual hours of production workers.

Furthermore, the CM reports gross earnings of all employees and all production workers

in each manufacturing establishment in each calendar year. Gross earnings of non-production

workers is the difference between these two. The price index for labor input is, therefore, the

total payroll divided by the Tornqvist index of total hours (L).

ΙΙΙC. CAPITAL

The appropriate measure of capital is capital stock rather than investment. Because

services flow from the entire stock of capital, rather than just new investment, stocks represent a

more complete picture of capital used as inputs to production. This is especially true in the case

of public capital where the standards for investment are not the same as in the private sector.12

Because the construction of the public sector capital series proceeded much like the

private capital series, we will discuss the general features of both before we discuss the specifics

of each. The database for state and county investment for U. S. total manufacturing industries

comes from the Census of Manufactures (CM) (Report by Geographic Regions); the database for

the public capital outlay for the states and counties was obtained from the Census of Government

publications (CG) report. Data are available for 1982, 1987 and 1992. Capital stocks are

commonly measured using "vintage aggregation" or a "perpetual inventory method" which uses

gross investment in constant dollars, an initial benchmark for the capital stock and a depreciation

rate or service life estimate. Therefore, estimating private and public capital stocks for the noncensus years require estimating capital outlays for each state and county.

 

12 See Michael Boskin, et al (1987) for details.
11

Investment was interpolated assuming that the annual values follow a geometric growth

rate between census years 1982, 1987 and 1992. The state investment values for both private and

public capital for each year have been controlled by the national totals. If investment in a census

year for the public sector was zero, the interpolation is done by assuming that the annual values

follow a linear path.

Moreover, since we have actual private sector data for the states from 1988 to 1991 (from

1992 Census of Manufactures Area and Industry series), these actual state values are used as a

control to interpolate county private investment values for those years. The basic idea is to scale

the observed county-level growth rates to be consistent with observed state-level growth. This

formula works well provided that the state changes in growth rates were not too large. Two

additional assumptions were imposed on the interpolation of the 1988 to 1991 period. A county

could not average more than three times its respective state’s growth rate over the 1987-92

period and a county level growth estimate could not exceed 99% or be less than –50%.

Capital stocks measures that are based on the perpetual inventory method need a

continuous gross investment series in constant dollars, a constant (geometric) depreciation rate

and a benchmark for the capital stock. We will first discuss these derivations for the private

capital stock series.

ΙΙΙC.1. Private Capital

The physical capital stock is defined as the sum of the stocks of structures or equipment.

The nominal investment data for the manufacturing sector (undifferentiated by asset type) were

converted to real 1992 dollars, by developing state level investment deflators. The ratio of the

state investment deflator to the national deflator was assumed to be proportional to the ratio of

state to national value-added deflators.

The private capital stock at the end of each period, Kt, is estimated as a weighted sum of

investments of age s at time t {It-s}:
12

Kt =s=0 ∑

∞

Φ(s)It-s (4)

where s is service life of the asset and Φ(s) is the relative efficiency index of an s year old asset.13

We assume that depreciation occurs at a constant (geometric) rate (δ) in which case the relative

efficiency index could be expressed as:14

Φ(s)=(1-δ)

s

(5)

Therefore, by substitution of equation (5) into equation (4), the formula to estimate capital stock is:

Kt =s=0 ∑

∞

(1-δ)

s

It-s

(6)

The depreciation rates for equipment and structures for the state and county

manufacturing sector are imputed from national level data by inverting the perpetual inventory

method to solve for the national depreciation rate:

δ = 1- [Kt-It]/Kt-1 = -{ [Kt- Kt-1 -It]/ Kt-1 }. (7)

ΙΙΙC.2. Computation of the benchmark private capital stock in 1982

To determine an initial capital stock, we assume a county’s share of the total capital stock in 1982

is proportional to its share of total capital payments (value of shipments minus payroll and cost of

materials) in 1982.15 The productive capital stock of 1982 benchmark was apportioned into

equipment and structures at the state and county levels in the same proportion as stocks at the

national level.

Aggregate capital input for the private sector (K) is computed as a Tornqvist index of

equipment and structures stocks, with the share weights employing national level estimates of

rental prices for total manufacturing taken from the Capital Measurement Program of the Office

of Technology and Productivity in the Bureau of Labor Statistics.16 It uses a Hall-Jorgenson

 

13 See “Trends in Multifactor Productivity, 1948-1981”, BLS Bulletin 2178 for details.

14

 BLS uses a more complex hyperbolic age-efficiency function, but given all the assumptions required here, geometric

decay is sufficient.

15 This is equivalent to the assumption of the rental price being the same across counties in 1982.

16 See Multifactor Productivity Trends, 1997 (March 1999).
13

rental price measured as the sum of an implicit rate of return to capital, a rate of depreciation, and

capital gains, all adjusted for taxes. Capital income for equipment is then the product of national

rental price and state or county capital stock. The income shares of equipment and structures for

each year are the ratio of each asset type income to all capital income:

ΙΙΙC.3. Public Capital

Public capital is defined as all capital outlays of state and local governments. Capital

outlays are available for the years 1982, 1987 and 1992. Construction of the public sector capital

series from the Census of Government follows the private sector capital. Total capital outlays by

asset types and capital outlays for selected governmental functions of states are reconciled to

national level infrastructure capital outlays. These investments by asset types and for certain

governmental functions by state and counties were deflated using national level price defaltors

derived from BEA data. Therefore, at each level of government, stock measures can be

developed for both aggregate public capital accumulation and capital devoted to specific functions

(or "core" public infrastructure):-highways, utilities, sanitation, conservation and development,

sewerage systems and education.

State and local public stocks of physical assets consists of equipment, land and

structures. The stock of capital for each public sector asset by function is computed using the

perpetual inventory method. For government nonresidential structures and producers durable

equipment, the service lives come from BEA’s Fixed Reproducible Tangible Wealth, while the

depreciation rates come from BLS’ Capital Measurement Program. Land is assumed infinitely

lived.

The BEA service lives used for the various asset types of state and local government

capital are: equipment 15 years; educational, hospital and “other” buildings, 50 years;

conservation and development, highways and streets, sewer and water structures, 60 years; and

“other” structures, 50 years. These estimated service lives for the various types of state and local

government capital are used to infer depreciation rates obtained from BLS.

While there are state and local government asset service lives for structures by

function from BEA, there are no published state and local government service lives for equipment

by function except by asset types. The depreciation patterns of public equipment likely resemble

those of private assets. Therefore, the service lives for the state and local publicly owned

equipment is synthesized by averaging the different service lives of similar assets that are privately

owned. Also infrastructure stocks are over 90 percent structures and so information on the types

of equipment is not vital.17

Table 2 shows the depreciation rates (δ) that are assigned to public sector durable

equipment and nonresidential structures by function:

 

17 For example, Aschauer (1989) bifurcated total nonmilitary capital stocks into structures and equipment so that they have

separate effects on productivity; and found that structures (93% of the stock) is of primary importance to productivity and

could be a good proxy for total nonmilitary public capital stocks.

ΙΙΙC.4. Computation of the benchmark public capital stock in 1982

The initial 1982 public infrastructure capital stock by function is generated by

assuming that the ratio of each states’ public capital stock (Gs,j,82) to the national public capital

stock (GN,j,82) by function is proportional to the ratio of each state’s public expenditure (Es,j,82)to

the national public expenditure (EN,j,82) by function. That is, Gs,j,82=Φs,j,82* GN,82 .

18

The 1982 benchmark capital stock is apportioned between equipment and structures for

each function by using the aggregate shares for each function across all states. These estimates

are then reconciled to national totals. Incidentally, 97 percent of infrastructure stocks are

structures in 1982 which suggests that we would not lose much information in our estimates even

if we work only with structures.

The next stage in the construction of public capital measurement is the estimation of

rental prices or user cost. The before-tax rental price is the sum of a rate of return (rG ) in the

form of opportunity costs plus depreciation costs(δG) less capital gains or losses arising from

changing asset prices:

P

18 This is equivalent to assuming that capital output ratio for each state function is identical across states. N stands for all

states or national value, s represents state or county and j stands for governmental function.
17

Since public capital income is not observable, rental prices cannot be determined from

observed data. Instead, we assume county governments optimize on behalf of their citizens. We

also assume that governments do not intend to resell assets. Accordingly, capital gains, ΔPt/Pt,

are irrelevant to the rental price calculations. Furthermore, counties do not pay taxes and so tax

effects can be ignored. Finally, since we cannot determine an ex-post internal rate of return, we

use a 20-year tax-exempt state and local bonds rate of interest (or high grade municipal bond) as

the opportunity cost for county governments. Given the simplified rental price formula and that

most assets are long-lived structures, rental price will not vary much across most assets.

Regardless, Tornqvist indexes of county assets are created using these simplified rental prices to

impute capital income asset shares. Table 3 shows the values used for rate of return (rG), and

depreciation rate (δG) variables that compute the rental prices of public capital.

It is important to note some of the differences in private and public sector capital inputs.

Unlike private inputs, public capital is a collective input which is shared not only by manufacturing

firms but also by other industries and residents of the region as well. The amount of public capital

that the manufacturing sector employs (or any sector for that matter) is less than the total amount
18

of public capital of the region. Since this cannot be observed, values of the entire public capital

will be used and the average effect for all public capital is measured.

After constructing private and public capital for counties and states for the three census

years, these data, together with other inputs, are used to estimate a production function along with

its share equations (equations 1 and 2). The sample employed more than 1500 counties. Since

some counties are not included in our sample (because not all counties have manufacturing plants),

we aggregated these 1514 counties into approximate state measures--‘pseudo-states’ and

compared these aggregates to actual data for the 50 states. The results of the actual state and

pseudo-state data were very similar, and accordingly, we report the actual state data regression

results.

ΙV. Estimation Results

The estimation of the effect of public capital on the gross output at the state and county levels is

based on the construction of public and private capital stock series. These state-by-state and county-bycounty capital series provide data for each of the 50 states in the U. S. and a little over 1500 counties for

the census years 1982, 1987 and 1992.

19

 There are 3040 counties in the U. S.; half were omitted because

either they had no manufacturing plants during the 1982-1992 period or confidentiality prohibited the

Census from reporting the data. However, as a group, the counties under study accounted for at least

80% of total state gross output and at least 85% to 90% of the total state private capital in manufacturing

in those three census years (see Table 4 below), but only for half of the total states’ public infrastructure

capital stock. Therefore, the distribution of private capital in manufacturing is more concentrated than

the distribution of public infrastructure capital. This might be an indication that public resources are

allocated by some other means rather than profit maximization, as is mostly done in private sector inputs.

Comparing the state and county public capital by type of asset, Table 4 also reveals that highways,

education and conservation are principally financed at the state level, whereas utilities, sewerage and

sanitation are funded mostly by local governments. According to Michael Boskin, et al (1987), highways

and education building account for 57 percent of total state and local government nonresidential capital.

In this study, after bifurcating the state and local capital, highways and education buildings account for

 

19 See Appendix Tables 1 and 2 for the 50 states and the largest 100 counties, stacked according to their private capital

stocks, for the values of their private and public capital for the three census years. Annex Table 3 presents private and

public capital stocks for the same census years for over 1500 counties by state considered for the study.
19

over 50 percent of state capital, whereas they account for only a little over 30 percent of county capital

for the three census years.20

As Table 4 also indicates, total state and county public infrastructure capital stock grew by

34 percent while private capital stock increased 65 percent between 1982 and 1992. The ratio of

state and county public capital to private capital showed a decline between these same periods.

Approximately two thirds of this public capital is state-owned.

The production function was estimated using a translog production function and using the

iterated seemingly unrelated regression (ITSUR) technique.21 The parameter estimates for

 

20 The study makes use of total public capital which includes such things as public school buildings and the like rather than

the ‘core infrastructure’ since the results of their estimates are similar.
20

county-level production functions for 1992 and their t-statistics in parentheses are displayed in

Table 5.22 Variables are entered in the translog production function as deviations from their

means to control for unobserved but state-specific fixed effects.23 In the later part of this exercise,

we will use a first difference form that would yet control for county level fixed-effects.

Column (1) shows the basic production function estimates without public capital. The input

elasticities closely approximate the observed income shares. The positive coefficients of the

squared terms in the private inputs offer evidence of either increasing returns in the private inputs

or the fact that some counties are at different production possibility curves.

 

21 The ITSUR method appears to fit the data better than the other estimation techniques. The iterated three stage

least square method (IT3SLS) estimation technique was used in preliminary computation with intergovernmental

finances (an important source of financing for local public expenditures) and population densities as instruments

for possible endogeneity, but the results were sensitive to the construction of the instruments and they were volatile

and less robust to specification changes than those based on ITSUR methods. Because of time and space, it was

not possible to provide all the detailed results for each regression. However, I would gladly provide this

information upon request.

22 The results for 1982 and 1987 are not shown since they have somewhat similar results as 1992, and the fact that 1982

was the benchmark year makes 1992 less sensitive to any problems that can arise in developing a benchmark.

23 To calculate county cross-sectional means, all the counties in a state under the study were considered as forming

respective “pseudo-states”. For example, even though Alabama itself has about 67 counties, under the study it has only 48

counties. Therefore, to calculate its mean, we total the value of the variables in log and cross-logs forms for the 48 counties

under the study and divide them by 48. This is the mean that is used to control for the fixed effects of the counties within

each state.

Column (2) adds infrastructure to the production function. The private input elasticities remain the

same. The estimated elasticity of public capital on private sector production for counties is positive for

all the cases (the cross-section (cols. 2 through 4), first difference (column 5) and pooled regression

analysis (column 6)). However, except the first difference which show an estimated elasticity of 0.133,

this value is a little more than 0.02 for the other equations and thus there is little evidence shown for a

special role of public capital in affecting output or productivity. The negative coefficient of the squared

term in infrastructure in the cross-section forms is an indication that public capital exhibited diminishing

returns.

One possible explanation for the non-significant role of public capital just might be a weak

relationship between infrastructure and output. A Pearson correlation analysis shows that even though

public capital and output are highly correlated (80%), the amount of infrastructure does not seem to rise

with per capita income (14%). It is generally believed that infrastructure is a normal good. Wealthy

counties will then have more infrastructure while the poor ones will have less, but the differences are not

large. This may explain the peripheral role played by infrastructure on private sector productivity and

output at both the state and county levels.

Column (3) adds regional dummies to control for regional amenities.24 Holtz-Eakin (1994)

demonstrates the importance of controlling for unobserved heterogeneity among states and introduces a

state-specific intercept into his estimation equation. In a similar fashion, we divided the states and

counties into broad based regions of north, south, east, and west to capture any effects that comes of

natural endowments. Regional differences did not reveal any additional information since regional

dummies do not appear to add more information than removing state means or fixed-effects from the

included regressors. The other parameters are largely unchanged.

Column (4) replaces regional dummies with Beale's codes in order to examine the possible existence

of productivity differences in manufacturing due to the degree of urbanization. Counties are stratified

into ten demographic groups: four metropolitan counties with population sizes of over 1 million to fewer

than 250,000; 3 adjacent and 3 nonadjacent to a metro with population of over 20,000 to fewer than

2,500. Because the estimation is done using deviations from their means to control for state-specific

effects, there is little or no change to the parameters indicating that there is no distinct pattern that comes

from urbanization at the county level.

Column (5) shows the estimates from the first difference form. This form controls for correlation

between unobserved county level fixed effects and output which may appear as a spurious correlation

 

24 See Holtz-Eakin, Newey, and Rosen (1988) and Tatom (1991) for details.
25

between public capital and output. The first difference form is a more stringent test than the state level

fixed-effects whose controls are somewhat limited. The first difference form may pick up more

information about each counties characteristics than state level fixed effects.

The results of the regression in first difference form showed a positive coefficient for public capital.

This implies an output elasticity of 0.133, a substantial effect. These results are not surprising when we

consider the fact that only census years 1982, 1987, and 1992 are used as a first difference. A new

highway system, for example, that was added five or ten years ago (i.e. in 1982 and 1987) would surely

add to the states or counties output in five or ten years (1987 or 1992).

Holtz-Eakin (1994) uses a year-to-year variation in his first difference form which may be influenced

by unobserved business cycle effects. This might explain why his first difference form estimate did not

identify the role played by infrastructure at the state and regional levels. Over the longer periods used in

this study, business cycles are minimized. Griliches and Hausman (1986) have suggested taking long

period differences in order to reveal important relationships among variables considered without a

simultaneity measurement bias.

One other possible explanation for the significant role of public capital for counties in first difference

form may be that although measurement errors are present in the data, they are approximately of equal

amount over time. Even though capital stock data is more appropriate than investment data, many

assumptions and interpolations were needed and the capital stock data may in general contain substantial

measurement error. The state values used in this study were reconciled to the national totals, but the

county values were not adjusted to the state totals since the counties under study do not comprise the

entire state. Thus the cross-county data is expected to pick up more noise than the cross-state data.

Taking first differences would then eliminate or reduce the errors in the data and biases in the estimates

drastically. However, it might also be the case that county level fixed-effects which was done using first

difference forms picked up more information about each counties characteristics than the state level fixedeffects.

Pooling cross-section and time-series data of the three census years, column (6), offers more degrees

of freedom for hypothesis testing and also introduces a time-series element for testing the applicability of

the specified model throughout the counties. Cross-county parameter estimates reflect inter-county

averages and thus are not applicable to each sample county. The pooled cross section specification

enables us to stress the cross-section variation while controlling for the time variations. If counties with

more public capital one year than the previous have more output during the year with more public capital,

it is a clear indication that increasing public capital will increase output and income. To take account of

the time dependent technological change, we incorporate yearly dummy variables for 1982 and 1987.
26

This specification allows the contribution of public capital to private sector output and productivity to

differ across counties and across time.

In the pooled regression for counties, public capital plays an insignificant role in the private sector’s

economic performance. The public capital coefficient from the pooled data for counties is zero or

negative. Even though time-series data is an important requirement to find the contribution of public

capital to private sector productivity, the fact that 1982 was the benchmark year makes the combined

data of 1982, 1987, and 1992 very sensitive to measurement errors. If that is the case, then the pooled

regression results may not provide us with a clear indication of the relationship between infrastructure

capital and output.

To allow us to conduct county and state analysis of the impact of public capital and private sector

productivity and to investigate the possibility of more spillovers for larger units of analysis, we conduct a

similar estimation at the state level. The parameter estimates and their t-statistics in parentheses for the

various cross-state equation results are displayed in Table 6. Because the Beale’s codes for U. S.

counties pertain only to counties, this model is dropped. The results of the estimates across the states

show elasticities of output that closely approximate income shares. While its magnitude and statistical

significance varies, a positive infrastructure effect at the state level remains unchanged regardless of the

modification done to the model.

Comparing county and state estimation results of Table 5 and Table 6, the evidence seems to suggest

that the estimated coefficient on public capital rises with the level of aggregation. As indicated in all the

cases (by the coefficient and output elasticity of public capital), the positive association between public

capital and state output is consistently larger than the positive association between public capital and

county output. The difference in findings may be due to the fact that using county data sets, one misses a

fraction of the spillover benefit from the public capital stock.

The county-level estimates may understate the overall impact of public capital since they cannot capture

overlapping effects that come from the higher levels of public capital (i.e., from state and national), while

estimates using state level data show somewhat a greater role for public sector capital than county

levels.25

Moreover, the ratio of per capita public to private capital is much larger for the states than for the

counties (84% vs. 21% in 1982). The counties under study also accounted for at least 85% to 90% of

the private capital in the state’s manufacturing sector, while these same counties accounted for a little

over more than half of the total state’s public capital stock. States are then in a position to capture

benefits of infrastructure more completely than counties as well as better positioned than counties to

choose feasible projects.26

The spillover elasticity of public capital on private sector output is positive and statistically

significant in all the cases except the spillover elasticity for the pooled county data that showed a negative

or roughly zero value. Based on the cross-sectional, pooled and first difference regressions, the results

also show consistently that public capital explain a larger portion of private sector output and

productivity at the state level than at the county level. This difference may be that aggregation does

affect infrastructure effects because states capture additional spillover.

Among the studies that report a positive public infrastructure contribution to the private

sector economy, one of the few consistent findings may be that these estimates increase with the

level of aggregation. Table 7 summarizes some of the empirical studies done by level of

aggregation with positive infrastructure contribution to the private sector economy.

The fact that the shadow price of public capital, Z G

, implies a higher level of return at the state

level than at the county level in all the cases partly also confirms that the higher the aggregation the

higher the spillover. However, when you carefully control for other things, the study finds that public

 

25 A regressor could be introduced in each of the equations that averages the public capital in adjacent counties (for the

over 1500 counties) and see whether it has a positive and statistically significant coefficient estimate to test if there is a

larger public capital spillover with higher level of aggregation. However, this test could not be performed in this case

because some adjacent counties are not in the study.

26 This result is consistent with some past findings such as Munnell (1992) that showed that the coefficients of public

capital would rise with the level of aggregation (where it was shown that regional data having a greater role of public

capital than state data). Munnell (1992) reports that her past and present findings of public infrastructure capital had a

positive impact on output at the state level, although the output elasticity was roughly half the size of her national estimate

(0.34 vs. 0.15). Munnell argues that spillover effects increase with the level of aggregation. The intuitive argument of

positive externalities is that at the less aggregated level one misses a fraction of the spillover benefits from public capital.

Based on Munnell’s estimate above, the output elasticity of infrastructure of 0.19 (the difference between national and state

values) is the out-of-state spillovers that are not captured by the state making the investment. Similarly, this study found a

larger out-of-county spillovers benefit than for the county making the investment.
31

infrastructure does have a small impact on output and productivity at both the state and county levels, but

that its influence is relegated to a peripheral role.

Moreover, the elasticity of output with respect to public capital, S G

, which helps us understand

infrastructure’s contribution to private sector productivity is 0.02 regardless of what model is chosen at

the county level, while it is at least 0.06 at the state level. Consequently, public capital’s contribution to

private sector productivity 

&

 at the county level is merely six-hundredth of a percent, while public

capital’s contribution to private sector productivity at the state level is two-tenth of a percent.

In general, parameter estimates for private inputs were robust to changes in specification such as

introducing regional and demographic dummies, first difference, and pooling the data of the three census

years, and the estimated parameters are of correct signs, and of reasonable magnitude for state and

county level analysis. The resulting high R2 (0.95 and higher in all the cases except for the county level

first difference form which registered an R2 of 0.84) in all the regressions provide a reasonable fit of the

sample. Moreover, the equations look sensible, with private input coefficients almost equal to their

shares of total income at both the state and county levels. When we consider the fact that common

variables together with infrastructure capital were able to explain a greater portion of output and

productivity, the model has performed adequately.

The negative cross effects among all the private inputs and between materials and public

capital in all the columns for the counties as well as the states indicate that they are substitutes,

while labor and private capital show positive and statistically significant cross effects with public

capital and thus they are complementarity at the county level and no effects at the state level. The

complementarity between labor and public capital as well as private and public capital could imply

that public capital enhances the operation of private capital, while the substitutability of public

capital and intermediate inputs indicate that public capital stock can directly affect economic

activity by reducing the need for some intermediates in private sector firms.

With similar past findings mixed, these results are not totally inconsistent. Hulten and

Schwab (1993), for example, found that private inputs (capital and labor) are the most important

sources of regional manufacturing differential in growth rates and not public capital. However,

they suggested that public capital may have played an essential role in facilitating the movement of

the private inputs. Eberts (1986) finds public capital and labor to be substitutes, while Deno

(1988) finds complementarity between the same two inputs. Dalenberg (1987) found that at the

regional level public capital and labor are weak complements while public capital, energy and

private capital are substitutes.

The negative cross effects among all the private inputs and between materials and public

capital in all the columns for the counties as well as the states indicate that they are substitutes,

while labor and private capital show positive and statistically significant cross effects with public

capital and thus they are complementarity at the county level and no effects at the state level. The

complementarity between labor and public capital as well as private and public capital could imply

that public capital enhances the operation of private capital,27 while the substitutability of public

capital and intermediate inputs indicate that public capital stock can directly affect economic

activity by reducing the need for some intermediates in private sector firms. With similar past

findings mixed, these results are not totally inconsistent. For example, Eberts (1986) finds public

capital and labor to be substitutes, while Deno (1988) finds complementarity between the same

two inputs. Dalenberg (1987) found that at the regional level public capital and labor are weak

complements while public capital, energy and private capital are substitutes.

Furthermore, the effect of public capital on the demand for private capital and labor as

exemplified by the cross elasticity between public capital and labor (respectively, hKG

and hGL)

at the state level is at least 4 percent for labor and at least 1 percent for private capital, while this

same value is zero or negative at the county level (except for the first difference form which

registered a 13.8 percent effect of public capital in the demand for labor).

In the next part of the exercise, the study will address the issue of productivity performance and

productivity convergence between the older well developed U. S. counties and the recently developed

counties as well as the role played by public infrastructure.

 

27 Hulten and Schwab (1993), for example, found that private inputs (capital and labor) are the most important sources of

regional manufacturing differential in growth rates and not public capital. However, they suggested that public capital may

have played an essential role in facilitating the movement of the private inputs.
34

V. Productivity Performance and Productivity

Convergence Across U. S. Counties

County level data allows us to address the issue of productivity convergence. This implicitly

tests the assertion that the older areas (with so-called deteriorating infrastructure and aging capital

stock) may have suffered in productivity growth relative to smaller more recently developed areas

of the U. S.28 Given that the U. S. has relatively homogeneous technology and work ethics, the

county level analysis is then a promising source of information on productivity growth and

productivity convergence (compared to comparative studies done of different nations with

different institutional arrangements such as cultural heritage, political stability, etc.).

Productivity convergence may occur by increasing capital intensity or attaining similar levels of

technology. Labor productivity (measures output/hour) does not allow the separate identification in

the influence of capital and technology, while the neoclassical growth framework places heavy

emphasis on accumulation of capital as the driving force behind convergence. Therefore, to compare

productivity across counties, it is important to consider both labor and multifactor productivity

measures. 29

The speed of convergence can be interpreted as the rate at which productivity is converging to

multifactor productivity measures is shown on Table 8 below.

 

28

 See, for example, Carlino (1985) and Carlino and Mills (1987). Studies have found the ‘Rural Renaissance” may

have resulted not only in the north losing to the south and west but also to their own hinterland.

29 See Bernard, Andrew B., and Charles I. Jones (1996) where these points are further expanded and statistically measured.

---------------------------------------------------------------------------------------------------------------------------------

The coefficients (β) on initial productivity levels are negative and significant for both labor and

multifactor productivity across states and counties. This indicates that lagging states and counties are

catching up to the most productive states and counties in the U. S. However, there is evidence for

faster convergence in multifactor productivity measure than in labor productivity measure. This may

suggest that more productive counties are able to offset some of the gains in MFP through relatively

greater capital investment.

This finding is somewhat in direct contrast to international studies done on productivity

convergence which find very limited or even non-convergence among the most productive compared

to the least productive countries. For example, in accounting for differences in output per worker

across countries, where their finding showed an output per worker 48 times higher in the most

productive compared to the least productive countries in 1988, Hall and Jones (1996) conclude that

differences in governmental, cultural and natural infrastructure are the main contributors to this

variation. However, for the U. S. states and counties where we have an established private property

rights, openness to trade, common language and a temperate climate, it would not be surprising for

the least productive to catch up with the most productive states and counties.

Furthermore, looking at the speed of convergence (λ) which determines how fast the less

productive counties catch up with the more productive ones, the state results show relatively rapid

convergence compared to county results. About 5.6 percent of the gap is closed in five years for the

states compared to only 0.8 percent for the counties. The corresponding figures for multifactor

productivity are 11.9 percent for the states versus 1.5 percent for the counties. This might be indirect
36

evidence of why infrastructure plays a larger role at the state level than at the county level since the

speed of convergence could be affected by spillover effects that come about from aggregation. This

could be one of the explanations as to why the results show the private economy responding more to

state level infrastructure than at the county level.

VΙ. Summary and Conclusion

Public infrastructure capital was incorporated as an additional input into a production function to

analyze its impact on private sector productivity at the county level. The county level is chosen as a unit

of analysis in order to minimize the impact of the macro-economy on the estimates. Counties are the

smallest geographical areas for which significant amounts of data are available. Because output is less

correlated across counties than across states or regions and at the county level, national influences are

considerably muted and the correlation between county level output growth and national growth are

weaker, analyses of infrastructure at the county level are more likely to measure the impact of

infrastructure on output.

The attempt to measure the impact of public infrastructure capital on private sector productivity

in various parts of the country is made possible by the development of private and public capital stock

at the state and, especially, at the county level. We constructed a measure of private and public

capital stocks based on the perpetual inventory technique for a sample of a little over 1500 counties

within the 50 U. S. states. The data is an effort to create a complete set of national accounts at the

state and county levels for inputs, outputs and public infrastructure at any level of industry in the hope

of allocating U. S. economic growth to its sources at local levels.

The next step was to determine if the county and state data can offer more direct evidence on the

impact of public capital on the growth of private sector output, productivity, and employment. We used

these data to estimate a translog production function to see if the positive relationship between output

and public capital (which has been documented at the national, regional, state, and SMSA levels) holds

up for county level analysis. The present study is based on a larger and broader sample that is largely

devoid of macro-economic influences than previous studies done on the topic.

The estimation of the system of equations for a large sample of counties suggests that the model

has great promise for evaluating infrastructure effects on the private sector economy. The

explanatory power of the cross-sectional, pooled and first difference regression are high with an R2 of

over 0.95 at both the state and local levels, except for the first difference form at the county level with

an R2 of over 0.84.
37

By and large, the results of the study are mixed and thus suggestive but hardly conclusive. The

spillover elasticity of public capital on private sector output is small but positive and statistically

significant in all cases at both the state and local levels, except when data are pooled for the three census

years. The spillover elasticity for counties in this case is negative or roughly zero. The results also show

that the spillover elasticity for states is consistently larger than the county data. This difference may be

due to states capturing cross county spillover. Because the translog estimation is done using deviations

from their means to control for unobserved county specific effects, state-level and county-level estimates

show no regional productivity differences and nor differences by levels of urbanization.

The study also examines productivity performance and productivity convergence across states and

counties. Productivity convergence may occur by increasing capital intensity or attaining similar levels of

technology. This implicitly tests the assertion that the older counties with aging capital stock may have

suffered in productivity growth relative to smaller more recently developed counties of the U. S. The

estimates show that while convergence is slow, it is occurring faster at the state level than at the county

level, which has a similar implication of spillovers increasing with the level of aggregation.

The results suggest that much could be learned by examining the public infrastructure-private

output relationship from a large micro sample, especially for time series. In addition, public sector

capital could be divided into different components of public capital such as highways, natural

resources, utility, sanitation, sewerage system and education to determine the relative impacts of these

various capital stocks on private sector productivity. It would also be interesting to consider

intergovernmental fiscal relations, because decisions made at the federal and state levels of

government may affect the incentive to invest (therefore the marginal product) in public infrastructure

of the metropolitan and county levels of government. Counties and states exhibit a wide array of

fiscal behaviors and economic growth patterns and the available samples should be large enough to

produce reliable cross-county estimates.
