Principles of Political Economy: Intelligence, Capital and Interdependence in the Modern Economy is a 665-page contemporary treatise by Roberto Balbino on how a modern economy produces, shares, finances and governs its prosperity.
It starts from a gap that headline figures hide: an economy can grow more productive while households feel less secure, and a company can post higher profits while depending on fragile suppliers. The book follows how production becomes income, how income becomes purchasing power, how financial promises are kept, and who carries the costs and benefits of change.
The structure follows the five-book architecture of John Stuart Mill's Principles of Political Economy, through the 1885 edition abridged and annotated by J. Laurence Laughlin. Book I covers production, from skills and capital to infrastructure and supply chains. Book II covers distribution: wages, ownership, housing, pensions, platform work and the division of gains. Book III covers money, banking and credit, then trade, exchange rates, tariffs, reserve currencies, China, the United States and Argentina's stabilization. Book IV asks what counts as progress, with conditional paths to 2030 and 2040. Book V examines government: taxation, public debt, competition, financial regulation, climate and satellite spectrum.
The analysis is non-partisan and evidence-based: identities, models, estimates and forecasts are kept apart, and outside research is credited to its authors. A synthesis of the book's propositions, a glossary and full references close the volume. Research cutoff: 21 October 2026.
