Wealth and the Global Economy: How Prosperity Devours Itself

Measurement & Methods: Externalities & True-Cost Accounting Introduction The gap between market prices and the actual costs that economic activities impose on society represents one of the most fundamental challenges in contemporary economics and policy design. When a factory pollutes a river, when agricultural practices degrade soil, or when consumption generates climate-forcing emissions, the prices paid by consumers and producers fail to reflect these broader societal costs. This systematic divergence emerges from the nature of externalities themselves—costs and benefits that fall upon parties outside the market transaction, making their internalization technically and conceptually complex. True-cost accounting (TCA) and sophisticated externality measurement methodologies have emerged as frameworks designed to render these hidden impacts visible and quantifiable, enabling more accurate economic decision-making. Understanding these measurement approaches requires examin...

Measurement & Methods: Distribution Metrics & National Accounts The essay is structured into six major parts: Part I: National Accounts Framework examines the System of National Accounts (SNA) as the international standard, explains the three approaches to GDP measurement (production, expenditure, and income), and details how supply and use tables integrate these approaches for consistency checking. Part II: Distribution Metrics analyzes the conceptual foundations and construction methods for measuring inequality, covering the Lorenz curve, Gini coefficient, percentile ratios (including the Palma ratio), entropy-based measures (Theil index and Generalized Entropy family), and the Atkinson index. Each measure is explained with its distinctive advantages and limitations. Part III: National Accounts Compilation addresses the practical methods of data gathering, explaining statistical data collection systems, non-observed economy measurement, price and volume measurement te...
