Why This Paper Exists
Economics has traditionally been organized by topics, methods, or schools of thought. While useful, these classifications obscure a deeper structure: how the discipline evolves through transformations in the constraints that define economic problems.
This paper introduces a new organizing principle: structural arcs.
Rather than asking what economics studies or how it studies it, the paper asks a more fundamental question:
What constraints does each major contribution transform—and how do these transformations propagate across the discipline?
What the Paper Does
The paper develops a structural framework that:
- Defines arcs as transformations in the constraints that govern economic reasoning
- Organizes Nobel-level contributions into a coherent architecture of ten arcs
- Distinguishes between formal, methodological, and interpretive influence across contributions
- Shows how ideas propagate not linearly, but through cross-arc interactions
- Establishes a networked view of economic thought, where influence is structured rather than diffuse
This is not a history of ideas. It is a reconstruction of the discipline’s internal architecture.
The Core Contribution
At the center of the paper is a shift:
From → organizing economics by fields or techniques
To → organizing economics by constraint transformations
Each arc captures a distinct rupture:
- From equilibrium existence to computable structure
- From optimization to allocation under constraints
- From isolated agents to strategic interaction
- From perfect information to informational asymmetries
- And beyond
Together, these arcs form a constitutional map of modern economics.
Why This Matters
Without a structural map, the discipline appears fragmented—divided into subfields, methods, and debates.
This paper shows that:
- Economics is internally coherent, but that coherence is structural, not topical
- Major contributions are connected through transformations of constraints, not just shared subject matter
- Influence operates through propagation across arcs, shaping how problems are defined and solved
This has implications for:
- Research design
- Teaching and curriculum structure
- Interpretation of economic theory
- The integration of new methods, including AI
Position Within the Bank & Finance Research Program
This paper establishes a foundational layer for understanding economic knowledge itself.
If financial systems require stewardship through design, diagnostics, and stress testing, then economics as a discipline requires:
A clear architecture of how its ideas are structured and how they evolve.
This paper provides that architecture.
