Bruce D. Baker, AEFA 2009 Rearranging Deck Chairs in Dallas: Contextual Constraints and Within District Resource Re-allocation in Urban Texas School Districts Bruce D. Baker Rutgers University AEFA 2009 Nashville, TN
Bruce D. Baker, AEFA 2009 Research questions • How do aggregate resource levels and teacher characteristics of urban core districts compare with their surroundings? • How do fiscal resources and teacher characteristics vary across schools within large urban districts? • How does need and cost related variation within large urban districts fit within the broader labor market of resource variation among schools in surrounding districts? • That is, is the district a sinking ship facing potential constraints on within district re-allocation? • To what extent does existing variation in resources account for the marginal costs of providing equal educational opportunity across schools within large urban districts and between large urban districts and their surroundings?

Bruce D. Baker, AEFA 2009 Data & Analyses • 3-year panel of 1409 Texas Elementary Schools in 5 major cities in 4 Core Based Statistical Areas • Why only 3 years? • To be able to estimate marginal cost model based on consistent outcome measurement. • Models • Expenditure decomposition • ln(expend) = f(size, students [se, lep, pov]) • Drop SE marginal expend • Drop small schools • Models estimated within city districts • Poverty slope projection • ln(expend) = f(Pov x District) • Excluding SE and small schools • Estimated for each CBSA, with Pov x City District interaction • How does the district’s poverty slope fit within the CBSA (and how do the intercepts align? (is the district a sinking ship?) • Cost model • Expenditure function, including outcomes (instrumented) & efficiency controls • Model estimated across all districts within 4 metros

Table 4 Factors associated with Cost Adjusted current spending Bruce D. Baker, AEFA 2009 Dallas “underfunds” schools which have more students with disabilities (relative to cost model) Houston “underfunds” higher poverty schools relative to marginal costs of equal opportunity (average outcomes) Ft. Worth and Austin achieve neutrality (statistically) with respect to marginal costs related to poverty concentrations *p<.05, **p<.10

Bruce D. Baker, AEFA 2009 Conclusions/Policy Implications • Austin and Ft. Worth ISD seem to be best targetting resources on the basis of school level poverty, but are also reasonably well positioned to do so. • Houston has accomplished a relatively flat distribution, whereby the Houston poverty slope is lower than the marginal cost slope. In this sense, Houston’s WSF has actually worked against the goal of providing equal educational opportunity. • Dallas appears to be resource constrained when considering only elementary school budgets. These constraints severely limit Dallas’ re-allocation options. It’s like … • Dallas appears to fund middle schools well, but also allocates less to high schools • District level finance data provide conflicting evidence regarding available resources in Dallas
