GHDP™ I — Time as a Binding Economic Constraint

This paper is the first in the GHDP™ (Gross Human Dynamics Product) series. It establishes time as a binding economic constraint and introduces GHDP™ as a macro-financial framework for analyzing system performance under temporal and cognitive limits. This work is conceptual and foundational in nature. It does not propose policy metrics, wellbeing indices, or empirical applications. Subsequent papers in the GHDP™ series address boundary conditions, diagnostic interpretation, and failure dynamics. This paper should be cited as the definitional reference for the GHDP™ framework.
