This paper proposes a theoretical framework describing a revenue maintenance mechanism in constrained economic systems. It argues that in sectors characterized by demand constraints (essential goods, mandatory services, or limited competition), a decrease in consumption volume does not necessarily reduce total revenue. Instead, prices adjust upwards to compensate for volume contraction. The model introduces the concept of an incompressible consumption threshold (Vmin), below which consumption cannot fall. In such systems, demand becomes rigid rather than elastic, making price the dominant adjustment variable. This mechanism leads to a form of structural inflation that is not driven by economic growth, but by internal system constraints and revenue preservation strategies. Applications are discussed across multiple sectors, including energy, healthcare, housing, telecommunications, and education. Keywords: structural inflation, constrained demand, revenue maintenance, price dynamics, economic systems.
