are the motives guiding to improve educational
opportunity for all students. Policy efforts as well as culture of
the schools accountability for results are the issues. Can
spending produce meaningful results?

involvement in the school budget. The ongoing question of what
is important or valuable. The extensive large study

Abstract: This paper uses the school finance reforms in
California in the 1970s
to examine whether the constraints such reforms impose on
school districts lead to
switching to private schools. Misspecifications of demand in
previous work have led
to understatement of reform effects. An empirical model of
schooling share
equations is derived from a discrete choice framework. Large
biases are shown to
result from failure to account for heterogeneity of demanders
and school-district-
specific fixed effects. Simulations indicate that the changes in
public provision
potentially resulting from reform explain a sizeable portion of
the growth in the
private school share. Q 1998 Academic Press

documents the large
5. and persistent disparities in educational opportunities within the
United
States. Policymakers have responded to these disparities with
various
reforms of state school financing systems, with varied success
at reducing
cross-district disparities in per pupil spending. Reforms that
have in-
creased the state share of spending and have limited local
discretion

However, the ef-
fects of these policies on student achievement and on other
aspects of

Contemporary observers of reform policies noted that reforms
limiting
local discretion over spending might have unintended and
potentially
detrimental consequences. For example, Walter Mondale

The end result could be reduced popular support for the state’s
public
schools, with the potential outcome being that the policies hurt
those
students in low wealth districts whom the policies were
intended to help.
The objective of this paper is to provide evidence on the
plausibility of the
argument raised by Mondale. In particular, we look at the
changes in the
share of enrollment in private schools after reform, using data
7. from
California in 1970 and 1980, years that sandwich extensive
school finance
reforms in the 1970s.
Two court rulings, Serrano I 1 and Serrano II,2 issued in the
mid-1970s,
dramatically altered the nature of public school financing in
California.
These decisions ruled unconstitutional any financing system
that allowed
disparities in taxable wealth across districts to translate into
disparate
levels of per pupil spending. Prior to the Serrano decisions,
there was wide
variation in per pupil expenditures, interpreted by the California
Supreme
Court as being partly attributable to sizeable differences in the
revenue-
raising capacity of districts. The state responded to the Serrano
decisions
by placing ceilings on the amount districts could spend on each
student
and by forcing the range in these ceilings on per pupil
expenditures, known
as revenue limits, to shrink over time. The passage of
Proposition 13, the
property tax limitation initiative, moved the responsibility for
financing
public schools from the local to the state level and enabled the
state to
implement the revenue limit system. The combination of the
Serrano
rulings and Proposition 13 did, with certainty, reduce the
differences in
8. w xspending across districts 18, 6 . The rapidity and magnitude
of the changes
in the cross-district distribution of per pupil spending provide a
natural
experiment for examining the effects of finance reforms.
w xFischel 11 has contended that the passage of Proposition 13
was
evidence that the Serrano decision reduced popular support for
public
school expenditures. Following Walter Mondale’s reasoning,
this reduction
in support also would be reflected in sizeable growth in the
share of
enrollment in private schools. In fact, in the late 1970s, there
was a rapid

w xincrease in the private school share. Yet, Sonstelie 22 and
Chamberlain
w x3 claimed only a small fraction of the changes in
California’s private
school enrollment could be attributed to the finance reforms.
In this paper, the conclusions of this previous work are
questioned. The
estimates presented here make a strong case that the reform’s
impact on
the enrollment share of private schools was large. The failure of
earlier
9. work to consider several important determinants of demand for
education
led to understatement of the estimated effects of reform. The
analysis
below explores the impact of the potential biases and presents
improved
estimates of the response to finance reforms.
The remainder of this paper is divided into six sections. The
next section
places California’s trends in private school enrollment in a
national con-
text. The third section outlines the empirical model used to
examine the
relationship between finance reforms and changes in aggregate
demand
for public schooling. That section also includes discussion of
how varia-
tions in individual tastes can be incorporated into the
specification of
aggregate demand. The fourth section describes the data used in
the
analysis. One important aspect of the data is inclusion of
information on
projected future public school spending levels, of particular
value since the
effects of reforms were not fully observable in the distribution
of per pupil
expenditures in 1980.
The fifth section provides estimates of the empirical model.
These
estimates confirm the importance of accounting for unobserved
determi-
nants of demand common to residents of a locality and for
heterogeneity
10. of individual demand. The results also support the argument
that individu-
als’ schooling decisions depend on expectations of future
quality of educa-
tion. These findings are confirmed by simulation results in
Section 6. The
final section summarizes the results and discusses their
implications for
policy and future research.
2. NATIONAL TRENDS IN PRIVATE SCHOOL
ENROLLMENT
Figure 1 includes plots of the percent of total students enrolled
in
California private schools and the percent in the nation for the
period
from 1972]73 to 1979]80. Nationally, approximately 10.0% of
all students
attended private school for the entire eight-year period, with a
mild
upswing in private school enrollment over the last few years of
the decade.
In California, after an initial downswing, in 1974 a period of
rapid and
sustained growth in the private school share began.3 The
number of
3The growth in the fraction private in the 1970s was at variance
with previous history in
California. In 1890, 8.81% of the enrollees in California
attended private schools. The
fraction of students in private schools remained at about this
level throughout the 20th
century.

students served by private schools increased by 22.35% to
497,613 stu-
dents, while the number served by public schools fell by 6.6%
to 4,119,511
students. This unprecedented change in the role of the private
schooling
sector coincided with the initial state response to Serrano I.
Figure 1 also gives trends in the private school share in several
other
states that implemented school finance reforms.4 The fraction
attending
private schools grew in most of these states, with Minnesota the
lone
exception. Still, even if reforms explain part of the increase in
the fraction
private, there were potentially diverse and unique factors
leading to
growth in each state. For example, in South Carolina much of
the exodus
of students from the public schools was attributable to
implementation of
desegregation programs. Nonetheless, the differences between
reform
states and the nation as a whole in the growth of the enrollment
share of
private schools indicate that the California experience may not
have been
unique. Further exploration of the relationship between the
12. growth in
the private school share and the implementation of finance
reforms is
warranted.5
4Enrollment shares were obtained from statistical abstracts
issued by the states. Reform
states are those states which implemented school finance
reforms intended to reduce
w xinequalities across school districts in per pupil spending.
See 1 for a list of reform states. Of
the states in this figure, only California and Washington
reformed their school financing
systems in response to court mandates.
5
w xThe need for such further exploration is also suggested by
Schmidt 20 , who, in examining
cross-MSA variation in private school enrollment, finds
evidence of a positive link between
the existence of state-imposed limits on revenue increases and
private school shares.
DOWNES AND SCHOEMAN422
The large interstate variation in the structure of education
financing and
in the nature of finance reforms implies that cross-state
comparisons of
aggregate trends are likely to fail to reveal many of the critical
dynamics of
public]private choice. We instead focus on the changes within
13. California.
The disparate effects on different districts of the finance
reforms make
California a natural case for evaluating the relationship between
private
school enrollment and finance reform.
3. AN EMPIRICAL FRAMEWORK
The starting point for the empirical model is the now standard
random
utility model. To apply this model in this context, several
assumptions need
to be made about the nature of individual choice. First,
individuals are
assumed to be immobile in the short run.6 In other words, the
local public
school is the only public alternative in the choice set. The
second assump-
� .tion limits alternative schooling choices private schools to
those within
the county in which the individual resides.7 Since the empirical
analysis
focuses on the schooling choices of families with children of
elementary
school age, such an assumption is reasonable because
transportation and
time costs make it prohibitively expensive for most students to
attend
school outside of their own county. In the model, we also
assume individu-
als act as if their choices will have no effect on the ability of
the schools to
provide education; individuals are taken to believe there is an
elastic
14. supply of schooling of a particular price and quantity.8
However, in the
empirical work below, we allow for the possibility that private
school
characteristics are endogenous.
An individual will choose to leave public school and enter
private school
if the utility gained from going to private school is greater than
the utility
6Given the distributional assumptions made below, we only
need maintain the assumption
that the cost of moving to a district providing higher quality
exceeds the costs of attending a
private school of equal or greater quality.
7In several rural counties, the choice set was broadened to
include the county of residence
and one or more neighboring counties.
8In effect, we maintain the assumption that, at any point in
time, the number and location
of private school options and the quality of public school
options are exogenous. Elements of
this assumption are defensible, particularly since the statutory
changes in California severed
any clear dependence of public provision on the share of
students in private schools.
Nevertheless, a more realistic model would make schooling
choice part of a broader public
choice problem in which public schools, private schools, and
individual consumers choose
w xtheir strategies simultaneously. Such an approach is taken
by Sonstelie 23 , where the median
15. voter framework is adapted to allow for existence of a private
schooling alternative. While
this approach is attractive, it requires maintaining assumptions
that have been questioned in
w xthe literature. See 7 for discussion of the weaknesses and
strengths of the median voter
approach.

If information on choices of individuals is available, the
parameters of
� .1 can be estimated directly. For the period in question, no
such individ-
ual data are available. Instead, we have observations on the
fraction of
17. individuals in each district choosing public school. There is no
well-accepted
method for moving from individual demand, as summarized by
the choice
� .probabilities 3 , to a specification of aggregate demand.
� w xTo develop a specification of aggregate demand, previous
work e.g., 3 ;
w x.22 typically has assumed demand in each community
corresponds to the
demand of a representative individual. This assumption is
correct if the
DOWNES AND SCHOEMAN424
w xconditions underlying the results of Tiebout 25 hold.
However, if tastes
are not homogeneous, ignoring information on higher order
moments of
the taste distribution will lead to biased results.
Schooling choice is a classic case in which accounting for
heterogeneity
in demand is critical. If communities are homogeneous, public
provision
will equal each individual’s preferred quantity of education.
Private school-
ing is sustainable only if communities are heterogeneous. A
model of
schooling choice that fails to account for heterogeneity is
inherently
contradictory.
To see how controls for taste variation can be built into a model
18. of

tion of individual characteristics within a district, let n be the

� � .. � .If we assume E R X is negligible, Eq. 6 gives a

� .Several aspects of the specification of aggregate demand in 6
are
worthy of comment. In moving from the specification of
individual demand
� . � .in 3 to the specification in 6 , no new parameters are
introduced. The
� .parameters b enter both in P m, b and in the derivative terms
M .0 k l
� .Since 6 is therefore nonlinear in these parameters, they can
be estimated
via nonlinear least squares. In addition, most of the data
required to
� .estimate 6 are provided in the Decennial Census. Available
for each
� .district are the fraction of students attending public school p
, the means0
� .
m of the characteristics of those choosing a schooling option,
and the
cross-tabulation information needed to calculate variances and
21. covariances
� . � . � .
s of those characteristics. Finally, since 3 is the basis for 6 , itk
l
� .continues to be the case that, if Q Z , X , F, b is linear in the
characteris-j i
tics of the choices Z , then aggregate demand depends only on
thej
differences between the characteristics of the public schools and
the
� .characteristics of the private alternatives. In other words, as
in 3 , the
coefficents are applied to the difference between the
characteristics of
each private school and the district’s public schools, summed
across all
private schools in the relevant county.
� .Since the specification of aggregate demand in 6 is based on
the
� .random utility model 1 , any potential determinant of
schooling demand
that does not vary across alternatives can only have an effect on
demand if
� . w xin 1 this determinant ‘‘interact s with a variable that
varies across
w xalternatives’’ 26, p. 27 . For this reason, we present
estimates derived from
specifications in which all individual characteristics enter only
through
their interaction with the pupil-teacher ratio.11
22. � .Moving from 6 to a workable characterization of aggregate
demand
requires dealing with a number of concerns raised in the
literature. Several
� w x w x.authors have argued Goldstein and Pauly 13 ; Reid
19 that, if individu-
als sort themselves into homogeneous communities, unobserved
determi-
10
w xSee 17 for an alternative discussion of the biases that can
arise if heterogeneity in tastes
is ignored.
11Since it is well established that Catholics may view public
and private schools differently,
we also estimated specifications that included the interaction of
fraction Catholic with school
type. The coefficient on this interaction did not differ
significantly from zero.
DOWNES AND SCHOEMAN426
nants of demand common to all residents may be correlated with
observ-
able individual and school characteristics. For example,
individuals who
are likely to attend private school may choose to reside in
communities
with low tax rates and high pupil]teacher ratios. Ignoring such
school-dis-
trict-specific effects can lead to biased estimates. Since we have
23. data on
� .private schooling shares in 1970 and 1980, we can estimate
variants of 6
that include the temporally stable, district-specific effects F
noted above.
A critical element of the choice model above is the diversity of
the
choice set of schooling alternatives. Previous research has
either omitted
characteristics of the private alternatives or assumed the choice
was
between the public alternative and a private alternative with
attributes
equal to the means of these attributes taken over all private
schools in the
region. But, just as biases can be generated by incorrectly
assuming there
is a representative individual, biased estimates can result if it is
assumed
there is a representative private school. In most of the counties
in this
sample, the private schooling options are heterogeneous and
thus poorly
� .approximated by a representative school. The specification
of P X; b0
� .given in 3 enables us to control directly for the heterogeneity
of the
private schooling options.
There are, however, two potential drawbacks to the conditional
logit
� .specification in 3 . The first of these is the imposition of
24. independence of
irrelevant alternatives implicit in this functional form. In the
context of the
w xfamous red bus]blue bus example, Train 26 notes that the
IIA problem
can be solved by including a bus-specific constant. Thus, by
including a
constant common to all private schools, we can lessen the IIA
problem.12
The second potential drawback of the conditional logit
specification in
� .3 is the fact that, ceteris paribus, the probability of attending
public school
is lower in regions with more private alternatives.
Mechanistically, this
drawback results from the fact that, all else equal, the more
private
� .alternatives there are, the smaller is the denominator of 3 .
The inclusion
of district-specific effects ameliorates this problem. Two
individuals can
face schooling options that have the same measurable attributes,
can have
the same personal characteristics, and can have different
probabilities of
attending public school if, in one district, the public schools are
viewed
more positively than in the other district. As a result, the mean
probability
of attending public school can be high in a district in which
there are many
private alternatives.
25. 12Other tractable solutions to the IIA problem require dividing
the private schools into
smaller groups. Then group-specific constants can be estimated
for each type of private
� .school or the nested logit form of P X, b can be used. Finer
groupings of the private0
schools were tried. Since the null of equality of the group-
specific constants could not be
� .rejected, we chose to present the estimates of the simpler
specification given in 3 .
FINANCE REFORM AND PRIVATE SCHOOL ENROLLMENT
427
One final specification consideration is that the characteristics
of the
schooling choices should include expectations about future
quality of
education. If changing schools is costless, individuals would act
as if the
only relevant information is the present quality of education.
Future
expectations would be unimportant, since waiting to transfer is
costless.
However, if changing schools imposes costs on the student who
transfers,
future expectations of school quality might alter an individual’s
decision to
remain in a particular school. If an individual currently enrolled
in public
school expects the quality of education in that school to fall in
the future
26. and future transfers are costly, then that student may decide to
transfer to
private school in the present period.13 In California in both
1970 and 1980,
current attributes of private schools were the best available
information on
future provision in those schools. Similarly, in 1970 public
school districts
had full control of spending; current provision was the best
available
information on future provision. But in 1980, the effects of
school finance
reform on future schooling provision had not been fully
reflected in
current provision. Other information, specifically the revenue
limit formu-
las that determined future spending, was potentially
instrumental in the
formation of expectations on future school quality. Districts
with slower
projected growth in revenue limits would have slower growth in
per pupil
spending. We explore the possibility that expectations of future
provision
were important by testing to see if the changes in the revenue
limits help
explain aggregate demand in 1980.
We consider below specifications of the aggregate demand for
public
� .schooling implied by 6 , starting with the representative
consumer version
typically considered in the literature. We use these results as a
starting
point to determine if previous conclusions concerning the
limited effects of
27. school finance reform hold up when expectations on future
school quality,
heterogeneity of tastes, and common, unobserved determinants
of demand
are taken into account.
13
w xDownes and Schoeman 9 contains a more rigorous
discussion of the role of expectations
on schooling choices when switching is costly. Another
argument for including measures of
w xfuture limits is suggested by Stiglitz 24 , in which he shows
that multiple equilibria in public
schooling provision are likely. If multiple equilibria exist, local
control over tax rates enables
the locality to coordinate the activities of its residents and
maintain a high activity equilib-
� .rium high tax and public provision . This high activity level
is feasible after the policy
changes of the late 1970s if each individual makes large
voluntary contributions to the public
schools, but no mechanism exists to coordinate at this
equilibrium. The result can be a low
� .activity equilibrium less spending on public education and a
larger private sector , even if the
w xexistence of peer group effects implies the high activity
level is Pareto superior 5 .
DOWNES AND SCHOEMAN428
28. 4. DATA
The data set used for this analysis consists of observations on
223
� . 14unified K]12 school districts in California in 1970 and
1980. The data
were drawn primarily from three sources: National Center of
Education
� .Statistics NCES surveys of private schools, California
Department of
Education records on school district finances and student
characteristics,
and the 1970 and 1980 Censuses of Population and Housing.
The NCES collected information on private school
characteristics in
1970]71 and 1978]79. For each year, the data include
information on
enrollment, staffing, location, religious affiliation, and type of
school
� . 15elementary, high school, special education .
The NCES data have three major problems. First, sparsity of
school
characteristics limits our ability to control for private school
quality.
Second, incomplete reporting results in omission of key
variables for some
schools. Finally, the price and quality of private education are
potentially
endogenous, since, in equilibrium, these variables depend on
unobserved
determinants of demand. To cope with the latter two problems,
we
estimated regressions of pupil]teacher ratios on school
29. characteristics
� .assumed to be exogenous religious affiliation, program type,
and location .
From these regressions, we determined predicted pupil]teacher
ratios.
The estimates presented below use these predicted values for
private
school characteristics.16 Even with these problems, the data on
private
school characteristics are more detailed than those used in
previous work.
Budgetary data from 1970 and 1980, compiled by the California
Depart-
ment of Education from accounting records of the school
districts, are the
source for much of the public school data. These reports include
informa-
tion on per pupil expenditures in and the location of the public
schools.
District-level data on student characteristics and performance
on standard-
ized tests are drawn from the California Assessment Program
data base.
These data were supplemented using printed reports giving
revenue
limits for the school districts for 1979 and 1985. In response to
the Serrano
decisions, the state placed ceilings on the amount districts could
spend on
each student. These revenue limits were first calculated in
1972]73 and
were based on the sum of each district’s locally generated
revenues and
30. w xnoncategorical state aid 6 . The state forced the range in
these ceilings on
per pupil expenditures to contract over time. Since the finance
reform
14The reasons for limiting our consideration to these districts
are given below. In 1980
63.9% of the students in grades K]8 resided in these districts.
15Average tuition data are not available for 1970]71 and are
available for a limited set of
schools in 1978]79. As a result, we cannot include a tuition
measure in the analysis below.

legislation established the formula for calculating these revenue
limits,
future revenue limits provide clear and observable signals of the
31. future
direction of public provision.
Demographic information was drawn from the 1970 and 1980
Censuses.17
For each school district, both censuses provide information on
the fraction
of students attending public and private school, the fraction of
the popula-
tion in particular income brackets, the racial composition of the
student
population, the fraction of the adult population with particular
levels of
educational attainment, and the fraction of families with
children. The
censuses include no direct information on the religious
affiliation of the
population of school districts. We proxied for the fraction
Catholic in each
school district using county-wide data from surveys of church
membership
conducted in 1970 and 1980 by the National Council of
Churches of
Christ.18
Finally, data on busing and other desegregation programs are
drawn
from New E®idence on School Desegregation, prepared for the
United
w xStates Commission on Civil Rights by Finis Welch and
Audrey Light 27 .
This report only includes information on the larger school
districts and
may thus fail to account for all desegregation programs, though
few small
32. districts were subject to court-ordered desegregation.
Table 1 presents the means and standard deviations of variables
used in
the analysis. Table 2 presents relationships between some of the
variables
of interest. Growth in district resources was influenced by
reforms; expen-
ditures grew more slowly and pupil]teacher ratios more rapidly
in districts
with slower growth in revenue limits. Given this observation,
the positive
correlation between the change in the fraction attending private
school
and the change in the pupil]teacher ratio is consistent with
finance
reforms contributing significantly to private sector growth.
Further, since
pupil]teacher ratios grew more rapidly in districts facing the
constraints
17The 1970 Census data are not available for smaller districts.
In California, most of the
districts for which data were not available were elementary
school districts. Since we were
concerned about the randomness of the elementary districts for
which data were available, we
chose to limit our analysis to the unified districts, for which
there was not a similar sample
selection problem.
18We also considered a measure constructed from the number of
non-Hispanic individuals
residing in the district whose heritage was an historically
Catholic country. While this latter
measure allowed for within-county variation in the fraction
33. Catholic, the empirical results
with the county-wide measure were more reasonable and more
consistent with previous
research on schooling demand.

5. EMPIRICAL RESULTS
In this section we present estimates of the parameters of two
variants of
� .Eq. 6 , each estimated using nonlinear least squares. The
first specifica-
� w x.tion closely resembles regressions estimated in previous
work e.g., 3 ,
with school-district-specific effects and information on the
distribution of
individual characteristics omitted. This specification differs
from specifica-
tions in earlier work only in that it includes controls for the
attributes of
private alternatives. These estimates thus provide a base case
for gauging
the importance of the omission of district-specific effects and
measures of
demand heterogeneity.

schools in the choice set.20 As is apparent from Table 1, this
weighted
average tended to be positive in 1980 since the public school
pupil]teacher
ratio was, in most districts, larger than the pupil]teacher ratios
for the
private schools in the choice set. Thus, for most districts in
1980, the sign
on the elasticity of the demographic variables was the same as
the sign on
the estimated coefficient on the interaction. Such was not
always the case
in 1970, since private school pupil]teacher ratios were
frequently larger
than public school pupil]teacher ratios.
The estimates in the first column result when we impose the
restriction
that aggregate demand for private schooling was stable across
time. The
second and third columns present estimates for the specification
that
allows aggregate demand to differ between 1970 and 1980.
Allowing the
specification of aggregate demand to change over time permits
us to
consider the possibility that attitudes toward public education

post- vs. pre-reform. Serrano and Proposition 13 did more than
simply
reduce inputs to public education; the constraints on local
discretion
changed the nature of public education in California. That this
change
could have altered the nature of aggregate demand seems
plausible ex
43. post. The estimates confirm that the underlying structure of
demand
differed between 1970 and 1980.21
Each of these specifications differs substantively from those
used in the
previous literature, but the implications of the estimates are not
different.
Inputs to the schooling process, measured here by the
pupil]teacher ratio,
are significant determinants of the demand for public schooling,
as is
apparent from the significant coefficients on the linear term, the
quadratic
term and many of the interaction terms. But the implied
elasticity of
demand with respect to the public school pupil]teacher ratio is
positive in
each year, counter to expectations. These estimates do not
support the
conclusion that reform-induced changes in the pupil]teacher
ratio con-
tributed to the move to private schools.
The estimated effects of the prospective change in the revenue
limit
temper the conclusion that there were no effects of reform.
Districts facing
future constraints in spending capabilities, as indicated by
negative real
growth in their revenue limits, have lower fractions of students
attending
public school in 1980. However, the magnitudes of the changes
in revenue
limits and of the elasticity of demand with respect to these
changes are not
44. sufficient to explain a significant portion of the exodus to
private schools.
w x w xThese results parallel those of Sonstelie 22 and
Chamberlain 3 :
families making schooling choices do not appear to have been
sensitive to
the reforms in public school finance. However, the specification
of aggre-
gate demand on which this conclusion is based fails to account
for
observed heterogeneity in the population of each district or for
unobserved
commonalities in the determinants of demand. That these
omissions are
critical to the conclusion that reforms do not matter is apparent
from the
results in Tables 5 and 6, which present estimates and the
corresponding
� .elasticities of variants of 6 that control directly for both
district-specific
effects and heterogeneity in the population of each district.22
21The Wald test statistic of the null of equality is distributed as
a x 2 random variable with
10 degrees of freedom. Since the value of the test statistic is
7891.2, we reject the null of
equality.
22In the estimation, we include dummyvariables for each
district. Because we have data for
each district, such a specification can be estimated. In effect,
we are assuming that there are
many individuals in each locality whose demand is influenced
by some common effect. As
45. long as we assume the asymptotics are driven by increases in
the number of people in each
community, all of the parameters can be estimated consistently.

One note of caution concerning the interpretation of the results;
the
census data provided less than perfect information for
calculating covari-
ances between demographic variables. Data on mean income for
each
education level were available only at the state level. The
variance of
income needed to be rescaled to make the model estimable.23
Also,

Even with this imperfect accounting for heterogeneity, the
qualitative
implications of the estimates are substantively changed from
those in
Table 3.24 The major change is in the response of demand to
changes in
w xthe public school pupil]teacher ratio. While, as Sonstelie 22
found,
in 1970 the elasticity of demand with respect to the
49. pupil]teacher ratio
is small, in 1980 demand for public schooling falls dramatically
as the
pupil]teacher ratio increases. For example, the mean elasticity
of demand
� .with respect to a change in the pupil]teacher ratio for Eq. 2
in 1980
implies that a 21.3% increase in the pupil]teacher ratio in the
public
schools, an increase equal to the difference in the mean
pupil]teacher
ratios between 1970 and 1980, would result in a 2.94% decrease
in the
public school share, all else equal. This is approximately 70%
of the 4.17%
decrease in the mean public school share.
The prospective change in the revenue limit continues to be a
significant
determinant of the fraction public. Further, the elasticity of
public school
demand with respect to this prospective change increases
relative to the
elasticity implied by the estimates in Table 3. Failure to control
for
24 � .We also estimated variants of 6 that accounted for only
district-specific effects or only
for population heterogeneity. Based on these estimates, it
appears that each of these
modifications to the base specification was responsible for

population heterogeneity and common, unobserved determinants
of de-
mand results in understatement of the role of changes in the
revenue limit
and, in light of the evidence above, in significant
understatement of the
influence of reform.
The demographic variables are interacted with the pupil]teacher
ratio,
so their effects on demand are only discernable from the
elasticities in
Table 6. The estimates of the effects of the remaining variables
are neither
stable across specifications nor across years, an unsurprising
result given
the scope of the changes in the decade of the 1970s.25 The
estimated effect
� .of income matches expectations only for Eq. 1 in 1970. The
positive
elasticity in 1980 for both equations indicates an increase in
mean family
income increases the fraction of students attending public
schools. Equally
surprising are the negative elasticities for the education
variables. These
elasticities imply that, all else equal, communities with larger
fractions of
individuals with less education have lower public school shares
than do
communities with larger fractions with post-graduate education.
51. However,
the income and the education results may reflect both the
increased ability
of higher income, better educated families to pay for private
school and
the greater ease with which such families can supplement in-
school inputs.
An equally plausible explanation for the negative education
elasticities is
that these elasticities signal the response to increased
heterogeneity in the
w xbackground of prospective students 14 .
Interpretation of the effects of the racial composition variables
is also
difficult, since the coefficients on these variables reflect two
potentially
disparate effects. First, these variables account for
heterogeneity in indi-
vidual views of public and private schooling. Second, they
reflect potential
responses to differences across communities in the racial and
ethnic
composition of the public schools. For example, the negative
elasticity of
demand with respect to the fraction African-American in 1980
implied by
� .Eq. 2 might imply African-Americans were more likely to
choose private
w xschool. However, in light of the work of Clotfelter 4 , this
result might also
indicate the presence of African-Americans in public schools
led to an
52. increase in private school attendance of other racial groups.
Unfortu-
nately, no measure of the student composition of public schools
in 1970
exists, preventing us from distinguishing between the two
effects.
In almost every case, the elasticity of public school demand
with respect
to the fraction Catholic is negative, consistent with the
expectation that
communities with larger fractions Catholic have larger fractions
of stu-

dents attending private school. Expectations on the effect of the
presence
of desegregation programs are also borne out. Districts with
desegregation
programs have less demand for public schooling.
These results confirm the implications of the trends in the
public school
share in reform states. Reforms and accompanying constraints
on local
discretion contributed significantly to the reduction in the
53. public school
share. In addition, the estimates above mask an important
difference
between this work and previous work: the inclusion of controls
for the
heterogeneity of private alternatives. Further, the results
abstract away
from the impact of reform on the supply side. The rapid growth
in the
number of private schools, from 1505 in 1970 to 2130 in 1980,
indicates a
supply side response cannot be ruled out. In the next section we
explore
how the public school share would have changed in the absence
of any
changes save for changes on the supply side.
6. SIMULATING THE EFFECTS OF REFORM
In this section, we present results of several thought exercises.
The first
asks how the fraction attending public school would have
changed if the
choice set had remained unchanged from 1970 to 1980, if
demographics
and the structure of demand had remained unchanged, and if the
direct
�effects of the finance reforms as measured by changes in the
pupil-teacher
.ratio and inclusion of the changes in revenue limits were
allowed to take
place. In other words, we use as our baseline estimates the
coefficient
estimates for 1970 in Table 5, Eq. 2. We restrict the private
54. schooling
options to those schools among the 1505 existing in 1970
located in the
county of residence of the family making the schooling choice,
and we
assume that the district demographics were as in 1970. The
public school
pupil]teacher ratio is assigned its 1980 value, and the influence
of future
expectations is accounted for by including the product of the
change in the
revenue limit and its coefficient. Under these assumptions, we
calculated
for each district the implied public school share.
Since in this simulation we assume that the finance reforms had
no
effect on the private school options or on the choice set, all of
the effects
of limits are assumed to work through changes in the
pupil]teacher ratio
and the revenue limits. These changes could understate or
overstate the
full impact of reform on inputs to education, but understatement
is likely
since no structural or supply-side changes are allowed. Still,
given available
data, this simulation provides the best measure of the magnitude
of the
demand-side effects of reform.
In this first simulation, overstatement of the effects of reform
could
result if some of the growth in the pupil]teacher ratio would
have
occurred in the absence of reform. However, if political support
55. for public
schooling had slipped, then this upward trend in the
pupil]teacher ratio

may have reflected a reduction in the statewide commitment to
public
education. For this reason, we cannot assume that the reforms
only
affected input levels in high wealth districts.26 Nonetheless, to
provide a
range of possible effects of reform, we also consider a variant
of the first
simulation in which we assume that none of the change in the
mean
pupil]teacher ratio and all of the reduction in the dispersion in
the
pupil]teacher ratio were attributable to finance reforms.27 To
implement
this assumption, in 1970 we assigned each district its 1980
pupil]teacher
� .ratio multiplied first by 22.454r27.229 , the ratio of the
mean
pupil]teacher ratios in 1970 and 1980. We continue to fix both
the choice
56. set and the characteristics of each district’s population at the
1970 levels.
The final thought exercise explores the changes in public school
enroll-
ment when the choice set is allowed to expand but when public
school
characteristics and demographics are fixed at their 1970 levels.
In combi-
nation with the estimates above, these three simulations provide
an indica-
tion of the extent to which the changes in the fraction of
students in public
schools can be attributed to the finance reforms.
Table 7 gives the predicted levels of the fraction attending
public school
under each scenario outlined above along with the actual levels.
The first
simulation indicates that, ceteris paribus, the changes in the
pupil]teacher
ratio from 1970 to 1980, together with the imposition of
spending limits,
would have led to a decrease in the fraction attending public
schools from
0.9071 to 0.8894. This change is 44.5% of the actual change in
the fraction
private. Even if this predicted change is an upper bound on the
reform-in-
duced change in the public school share, the case is made that
the finance
reforms could have generated a significant portion of the change
in
California private school attendance in the late 1970s.
The second simulation indicates that, unless the finance reforms
changed
57. support for public education at the state level, there is no
persuasive
evidence that the increases in the private school share can be
attributed to
the reforms. If only the reduction in dispersion in the
pupil]teacher ratio
is attributed to the finance reforms, the estimates imply that the
reforms
26It was apparent to most state residents that, after the finance
reforms, any increase in the
state government’s spending on education would be financed by
increases in revenues from
w xCalifornia’s progressive income tax 12 . Further, since high
wealth districts continued to be
w xless dependent on the state for funding their public schools 6
, residents of these districts
would be less affected by slower growth in the state
government’s spending on education.
Reform-induced opposition to increases in state spending could
have resulted in increases in
pupil]teacher ratios even in districts with the lowest property
wealth. The evidence seems to
confirm this view. Between the 1969]70 and 1979]80 school
years, the percentage changes in
average daily attendance in California and in the nation were
essentially equal. In that same
period, the number of teachers increased by 2% in California
and 8.4% in the nation.

would have had no effect on the private school share. In fact,
the share of
students in the private schools would have decreased slightly
from 0.0929
to 0.0887. Thus, it would seem that the actual impact of the
reforms could
range from no appreciable effect on the private school share to
the 19.1%
decrease in this share implied by the first simulation. The
strength of the
w xattitude changes in California 12 and estimates of the effect
of the
w xfinance reforms on spending on public education in
59. California 21 suggest
that the changes resulting from the reforms were near the top
end of this
range.
The results of the final simulation are far less dramatic. The
simulation
implies that, if individuals in 1970 had available the schooling
options
present in 1980, the mean fraction in public schools would have
fallen to
0.9055. These supply-side changes explain only 4% of the fall
in public
enrollment. Nonetheless, this simulation supports the argument
that, by
failing to account for the diversity of choices in private
schooling and the
changing nature of the choice set, earlier work has incorrectly
attributed a
portion of the growth in private schooling to time effects
uncorrelated with
observable determinants of demand.
7. CONCLUSION
In this paper we have shown that education finance reform
played a
major role in the rapid decline in California public school
enrollment
during the 1970s. California and other reform states exhibited
markedly
different trends in private school enrollment in comparison to
the rest of
the nation. In California, the rapid growth in the private school
sector
60. followed the implementation of reforms in response to the first
California
Supreme Court decision in the Serrano case. Further, that
private school

enrollment increased rapidly after the passage of reforms,
before any real
change in public provision occurred, indicates individuals may
have re-
sponded to changing expectations of future provision in the
public schools.
Previous studies have failed to obtain conclusive results on the
effect of
school financing reform. We argue this failure is attributable to
the
omission of several important determinants of the public school
share of
enrollment. To correct for these omissions, we work from a
simple qualita-
tive choice model to present several modifications to the basic
specifica-
tion of public schooling demand considered in earlier work.
Estimation of this modified specification leads to four main
findings.
First, failure to account for common, unobserved determinants
of demand
results in understatement of the role of reform. Second, the
inclusion of
spending limits, in addition to per pupil expenditures, provides
61. a truer
measure of perceptions of current and future public school
quality. All the
results are consistent with the claim individuals do make
schooling deci-
sions based on future quality of education. Third, even
relatively simple
controls for heterogeneity in the population that is making
schooling
choices improve the quality of the estimated schooling demand
equations.
That heterogeneity in demand is important should not be
surprising, since,
in the long run, private schooling can only exist if there is
variation in
preferred levels of education provision. Finally, information on
character-
istics of individual private schools provides better insight into
the nature of
individual demand for schooling.
In simulation results, we find a strong case can be made for the
claim
that the Serrano decisions led to a significant increase in the
fraction of
students attending private school. Our best estimate is that, in
the absence
of any changes in private schooling supply, the reform-induced
changes in
public schooling provision led to a change from 1970 to 1980 in
the public
school share equal to about 44.5% of the actual change. This
result may
understate the portion of the enrollment change attributable to
the fi-
nance reforms, since limited information on the determinants of
62. supply
prevents us from determining the portion of the change in
enrollment
attributable to supply-side responses to the finance reforms.
The main implication of these results is that the full range of
behavioral
responses must be considered when government-imposed limits
on local
discretion are implemented. In the case of school finance
reforms, if
constraints on local choice result in a popular backlash, the
relative
standing of students in poorer districts might be hurt.
Proponents of
finance reforms are correct in arguing that reforms to promote
equity
must account for differences in the costs and revenue-raising
capacities of
school districts. But aid formulas exist that adjust for such
fiscal disparities
while imposing no substantive limits on local choice in
spending. There is
almost no case for forcing equalization by eliminating local
discretion.
