### Overview
- Book reviewed: Visions of Inequality: From the French Revolution to the End of the Cold War by Branko Milanovic, Belknap Press, Cambridge, MA, 2023, 368 pp., $32.95.
- Reviewer: Zia Qureshi.
- Central contribution: a sweeping, erudite intellectual history tracing how economic thought about inequality evolved from the French Revolution through the end of the Cold War and into contemporary debates.

### Historical evolution of thinking about inequality
- Early framings:
  - Focused on social classes and means of production—landowners, capitalists, workers.
  - Emphasis on functional distribution of income—rents, profits, wages.
- Six foundational economists profiled (one chapter each): François Quesnay, Adam Smith, David Ricardo, Karl Marx, Vilfredo Pareto, Simon Kuznets.
- Pareto’s framing: inequality as a social hierarchy of elites versus the rest of the population.
- Kuznets and later neoclassical shift:
  - Analysis increasingly focused on individuals and interpersonal income distribution.
  - Shift aided by greater availability of individual income data.
  - Enabled study of income distribution across dimensions such as educational attainment and urban versus rural location.

### Cold War period: “long eclipse of inequality studies”
- Milanovic’s characterization: the second half of the 20th century was a “long eclipse of inequality studies.”
- Contributing factors to the eclipse:
  - Neoclassical economists’ faith in markets and market outcomes.
  - Moderation of inequality within Western economies due to:
    - Rising demand for labor supported by stronger postwar economic growth.
    - Improvements in education.
    - Introduction of social welfare programs.
  - Politics of the era: competition between capitalism and communism pushed economics into service of ruling ideologies, with each side presenting itself as less class based and less unequal.

### Recent resurgence of inequality research — drivers and causes
- Inequality has resurged in recent decades.
- Identified drivers:
  - Differential impacts of technological change and globalization across firms and workers.
  - Current institutional and policy settings, including:
    - The state’s weakened redistributive role as tax progressivity declined.
    - Social programs squeezed by tighter fiscal constraints.
- Geographical pattern of rising inequality:
  - Noted increases in Western economies, especially the United States.
  - Increases in post-Soviet Russia.
  - Increases in major emerging market economies such as China and India.
- Policy implication: these changes have prompted economists to refocus attention on inequality.

### Contemporary advances in the study of inequality
- Milanovic’s epilogue reviews modern developments in inequality research.
- Thomas Piketty highlighted for advancing analysis of wealth and nonlabor income in inequality.
- Broader compass of contemporary studies:
  - Move beyond narrow neoclassical market focus to include social and political power structures.
  - Incorporation of gender and race as factors.
  - Examination of inequality in dimensions beyond monetary income.
  - Expansion from within-country inequality to inequality among global citizens—Milanovic noted as pioneering work in this area.

### Global versus within-country inequality trends and future challenges
- Empirical juxtaposition:
  - Inequality within countries has been rising.
  - Global inequality (the sum of within-country and between-country inequality) has been falling.
- Reason: developing economies are narrowing the income gap with rich countries.
- Risks to continued convergence and future outlook:
  - Weakening world growth outlook, especially for developing economies.
  - Geopolitical tensions and the risk of geoeconomic fragmentation threatening trade and investment between countries.
  - Technology altering the structure of international comparative advantage.

### Assessment and readability
- Milanovic’s book judged:
  - Important scholarly work and a good read.
  - Mixes methodical examination with portraits of economists and the societies and polities of their times.
- Timeliness and warning:
  - Renewed attention to inequality is timely; large and persistent increases in inequality can have severe consequences, as documented by Walter Scheidel in The Great Leveler.
- Final evaluative comment: Visions of Inequality offers a rigorous account that situates contemporary concerns in historical context and helps explain why inequality has returned to the forefront of economic research and public policy debates.
