Economics is rarely the first discipline people associate with education. The field is more commonly framed through pedagogy, psychology, or policy. Yet some of the most durable insights into how education systems function have come from economic thinking.
Economists are trained to look for structure beneath complexity. They study how incentives shape behavior, how inputs interact, and how small design decisions create large downstream effects. When applied to education, this lens raises questions that are easy to overlook: not just whether a program works, but how it changes the behavior of the system that adopts it.
This way of thinking has increasingly influenced education research. One prominent example is the work of Thomas J. Kane, Walter H. Gale Professor of Education and Economics at the Harvard Graduate School of Education and faculty director of the Center for Education Policy Research. Kane has argued that progress in education depends on testing ideas in real settings and generating evidence that informs practical decisions, rather than relying on intuition or ideology alone.

Special education, in particular, reveals the value of this perspective.
Education as an Economic System
In economics, complex organizations are often described using the idea of a production function. Multiple inputs combine to produce outcomes, and the effectiveness of any one input depends on the others. This framework does not reduce education to a formula. It offers a way to understand why isolated improvements so often fall short.
Special education operates under especially tight constraints. Student needs are diverse. Staffing pipelines are fragile. Daily instructional decisions are numerous and consequential. In such environments, variability is expensive. When systems lack clarity or coherence, more responsibility is pushed onto individuals. Over time, this increases cognitive load, stress, and inconsistency.
From an economic standpoint, these pressures show up as familiar patterns:
- elevated turnover among teachers and paraprofessionals
- increased dependence on specialists
- growth in out-of-district placements
These outcomes are typically addressed as separate problems. An economic lens suggests they may be connected responses to the same underlying system conditions.
Curriculum as Infrastructure
Curriculum is not usually discussed in economic terms. It is often treated as content rather than structure. Yet curriculum shapes how time is spent, how decisions are made, and how work is distributed across a system.
Well-designed instructional systems reduce uncertainty. They create shared expectations, align materials with training, and limit the amount of daily improvisation required of educators. These features matter because decision-making has a cost. When that cost is high, it accumulates quickly in high-need settings.
From a system perspective, curriculum influences volatility. High volatility increases turnover. Turnover disrupts continuity and weakens implementation. Weak implementation then drives additional spending elsewhere, often in the form of external services or placements.
This is not an argument about any single program. It is an observation about how systems behave when core instructional inputs are fragmented or unsupported.
Compounding Effects Over Time
One of the central insights of economics is that effects compound. Small changes that alter feedback loops can produce outsized long-term impacts.
In special education, investments that stabilize instructional practice can set off a chain reaction. Reduced turnover preserves institutional knowledge. Preserved knowledge improves consistency. Consistency supports better student progress. Improved progress expands the capacity of systems to serve students effectively within district programs.
Each step in this sequence has fiscal implications. Out-of-district placements and emergency staffing are among the most expensive responses available. Systems that rely on them heavily are often responding rationally to immediate needs, but at significant long-term cost.
An economic lens reframes the conversation. Instead of managing these costs downstream, it asks which upstream decisions shape them.
Evidence as a Leadership Tool
Kane’s work emphasizes that progress depends on evidence that clarifies cause and effect. The goal is not to confirm existing beliefs, but to test hypotheses in real-world conditions and learn from results. (Harvard Graduate School of Education)
Applied to special education, this suggests a broader set of questions. Rather than measuring curriculum solely by short-term academic outcomes, systems might examine its effects on workforce stability, instructional consistency, and placement patterns over time.
These outcomes are rarely attributed to curriculum decisions. Yet they may be among the most consequential.
Practical Implications of a Systems Perspective on Special Education
Viewing special education through an economic lens highlights how closely instructional design, workforce stability, and cost are linked. Challenges such as turnover, inconsistent implementation, and costly out-placements begin to appear less as isolated issues and more as predictable outcomes of system design.
From this perspective, curriculum, when intentionally designed and implemented, functions as instructional infrastructure. It shapes daily decision-making, workload, and consistency across classrooms. When instructional systems reduce volatility, they influence not only educational quality but also the cost drivers that sit beneath special education budgets.
This matters because those effects extend beyond special education itself. Reductions in high-cost responses and greater system stability can create budgetary flexibility across the district, allowing resources to be reinvested in programs and services that benefit the broader student population.
Once curriculum is understood this way, it becomes difficult to evaluate it narrowly again. Not because it solves everything, but because it quietly shapes both educational outcomes and long-term financial sustainability.
