Model 1 in Table 4 indicates that a one dollar increase in foundation revenue and non-
foundation revenue lead to $.376 and $.283 increase in FB, respectively. The influence of
foundation revenue on fund balances intensifies, after controlling for the enrollment and resource
allocation variables, as shown in Model 5.
As expected, district enrollment growth also consistently exerts a significant positive
impact on district fund balances. Gaining one student increases fund balances by $.03 per total
district pupil. This implies that for growing districts the marginal revenue gain associated with
an additional student exceeds the marginal cost. Conversely, for declining enrollment districts,
revenues decline faster than costs, causing district fund balances to decline.
The results for the school choice variables are interesting. In all specifications, as
expected, a net inflow of inter-district student transfers significantly increases district fund
balances, and correspondingly net out-flows of students lower fund balances. By comparison,
the results for districts’ loss of students to charter schools are more tentative. While significant in
the parsimonious models (Models 3 and 4 in Table 4), %Charter is only significant at the 90%
level in the full model, after the resource allocation variables are introduced (Model 5). Below
we test for the possibility that very high and sustained levels of charter penetration have
differential impacts on district finances that are not captured in our linear specification of
%Charter.
It is noteworthy that the point estimate on Enrollment falls by 44 percent when the
charter school and inter-district choice variables are added in Model 3. This implies that 44
percent of the enrollment effect is explained by charters and inter-district choice. It also implies
that since Enrollment is included with the school choice variables, the point estimates on
18
%Charter and %Net_IDC do not reflect their full impact on district fund balances since much
their effects pass through enrollment.
Student characteristics also influence district fund balances. As expected, the percent of a
district’s students who are eligible for special education service is strongly related to district fund
balances. A one percentage increase in a district’s students receiving special education services
in Model 5 generates roughly a $43 decline in district fund balance per student. As noted above
(footnote 2), under Michigan’s special education funding arrangements, special education
students typically represent a financial burden to local districts, and the more costly a student’s
disability, the larger the burden.

Meanwhile, increases in the percent of students who are poor (%FRL) do not have a
similar negative impact on district fund balances. The percent of students who are eligible for
free and reduced priced lunch is positively related to district fund balances, although this
relationship is only marginally significant.
14
This implies that for Michigan districts as a whole,
the additional revenue they receive to serve low-income students roughly corresponds to their
additional spending for these students, producing no significant residual impact on fund
balances.
In Model 5, three of the five district resource allocation variables are significant (P-T
ratio, Teacher_Salary, and %Admin) each with the expected signs. An increase in a district’s
pupil-teacher ratio by one student increases its fund balance by $80 per pupil. Meanwhile, a
13
The portion of special education costs that are borne by local districts and charter schools varies across
intermediate school districts (mostly county-level agencies) in Michigan, because ISDs differ in the extent to which
they provide supplemental special education funding to the local units.
14
We explored the possibility that the impact of student poverty on fund balances is nonlinear, including
specifications testing for the possibility of differential budget impacts in districts with very high thresholds of
student poverty (e.g., %FRL = 70%, 80% or 90%). In none of these specifications was the measure of student
poverty statistically significant.
19
$1000 increase in average teacher salaries decreases fund balances by $29 per pupil. A one
percentage point increase in the administrative spending (as a share of total general fund
spending) lowers district fund balances by $112 per pupil.
Two of the district resource allocation variables, %Health and %Purchases, are not
significantly related to district fund balances. These results are noteworthy in view of the fact
that within the Michigan policy context both are associated with steps (cutting expenditures on
employee health benefits and contracting service provision to private vendors, respectively) that
have been widely advocated for local districts in fiscal distress (e.g.,Washburne & Jahr, 2007;
LaFaive, 2007 ). Whatever the merits of these strategies as emergency measures for district in
fiscal distress, our results fail to indicate that they are systematically related to districts’ fiscal
health as measured by their fund balances.

Whereas a simple correlation suggests that districts with high concentrations of African
Americans are more likely to be in financial distress, as indicated by Figure 3, our results in
Table 4 suggest a more nuanced relationship. Districts with high concentrations of African
American students are much more likely to be subject to intense charter school penetration, to
lose students to inter-district choice, and to have higher concentrations of students with
disabilities.
16
Once these and other factors are controlled, however, districts’ level of financial
distress is not significantly related to their racial composition as indicated by the %Black variable
in Model 6 of Table 4. Moreover the results for other variables are highly stable with the
inclusion of %Black in the model.
15
We also tested districts’ contribution rate to the Michigan Public School Employee Retirement System in our
models. MPSERS is a state defined-benefit pension system. The system’s eligibility and benefit provisions are
established at the state level, and it is funded by local districts through a uniform statewide contribution rate set
annually by the state and assessed against districts’ payroll spending. MPSERS contributions were not significant in
any of our models and its inclusion did not change the results for any other variables in the model.

The correlations between %Black and these variables in 2012 were: %Charter (0.654), %Net_IDC (-.092),
and %SpecEd (0.222). The correlations over the entire 1995-2012 period were: %Charter (0.601), %Net_IDC (-
.052), and %SpecEd (0.193). %Black is measured by head count data.
