Abstract

Conventional Development Assessment Often Examines Economic Production, Human Development, Institutions, Social Conditions, or Environmental Sustainability Through Partially Separate Lenses. Integrated Development Equilibrium Theory (IDET) Proposes a Unified Framework in Which Development Is Understood as the Interaction of Five Foundational Dimensions: Economic Vitality, Institutional Integrity, Human Capability, Household Welfare and Social Inclusion, and Environmental Sustainability and Resilience. The Theory Distinguishes Four Analytical Levels That Are Frequently Conflated: Developmental Capacity, Developmental Equilibrium, Conversion Effectiveness, and Developmental Comfort. Developmental Capacity Refers to the Resources, Capabilities, Institutional Conditions, Social Foundations, and Environmental Assets Available to a Society. Developmental Equilibrium Concerns the Degree to Which These Dimensions Remain Sufficiently Compatible and Mutually Supportive. Conversion Effectiveness, Represented Conceptually by the Developmental Conversion Efficiency Factor (Ω), Concerns How Effectively Capacity Is Translated Into Realized Human Outcomes. Developmental Comfort Is the Human-facing Outcome: the Extent to Which Development Is Experienced Through Security, Accessibility, Predictability, Dignity, Opportunity, Agency, and Sustainable Living Conditions. IDET Therefore Does Not Claim That Its Individual Dimensions Are Novel, Its Contribution Lies in Theorizing Their Interaction Through an Explicit Capacity - Equilibrium - Conversion - Outcome Architecture, Including a Weakest-link Mechanism and a Proposed Developmental Equilibrium Index (DEI). The Paper Develops the Philosophical and Theoretical Foundations of IDET, Reviews Relevant Development Traditions, Formalizes Its Core Relationships, Proposes a Preliminary Measurement Architecture and Empirical Strategy, and Uses Bangladesh Only as an Illustrative Application. The Study Is Theory-building Rather Than Empirical and Makes No Claim That Ω, DEI, or Developmental Comfort Has Yet Been Validated. The Paper Concludes with Falsifiable Propositions and a Research Agenda for Testing Whether Equilibrium and Conversion Effectiveness Explain Variation in Human Outcomes Beyond Conventional Development Indicators.
