Who is Who in Economics

"The division of labour is limited by the extent of the market."

Can help you with: The land value tax and why George thought it could replace all other taxes, the relationship between land rent and poverty, why Progress and Poverty sold more copies than any book except the Bible in the 1880s, and why his ideas are experiencing a revival.

"Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio." The clergyman who made economics the dismal science — and who was substantially right about the pre-industrial world, and substantially wrong about what industrialisation would do to it.

Can help you with: The Malthusian population trap and how it operated before 1800, the preventive and positive checks on population, the debate between Malthus and Ricardo on wages and rent, why the Industrial Revolution broke the Malthusian constraint, and what neo-Malthusian arguments about resources and limits get right and wrong.

"In the long run, we are all dead."

Can help you with: The General Theory and what it actually argues, the paradox of thrift, the role of government in managing aggregate demand, the relationship between Keynes and the Great Depression, and what Keynes actually believed versus what is called Keynesianism.

"Inflation is always and everywhere a monetary phenomenon."

Can help you with: Monetarism and the quantity theory of money, the natural rate of unemployment, the Chicago School and its influence, the negative income tax and basic income, and the relationship between Friedman's economics and his political philosophy.

"The curious task of economics is to demonstrate how little we know."

Can help you with: Spontaneous order and the price system, the knowledge problem and why central planning fails, the road to serfdom argument, the relationship between Hayek and Keynes, and what the socialist calculation debate was really about.

"Invention is the mother of necessity."

Can help you with: The theory of the leisure class and conspicuous consumption, institutional economics and why institutions matter, the predatory versus productive distinction in business, and why Veblen's satire remains one of the sharpest analyses of consumer capitalism.

"The market is an institution, not a law of nature."

Can help you with: The Great Transformation and the double movement, the concept of embeddedness — that economies are embedded in social relations, the critique of self-regulating markets, and why Polanyi's work is essential for understanding how market societies emerge and what they do to communities.

"Stability is destabilising."

Can help you with: The financial instability hypothesis, the three stages of debt financing (hedge, speculative, Ponzi), why financial stability breeds instability, the Minsky moment, and why mainstream economics ignored Minsky until the 2008 crisis proved him right.

Can help you with: Imperfect competition and monopolistic markets, the post-Keynesian critique of neoclassical economics, the Cambridge capital controversy, why Robinson never won the Nobel Prize despite deserving it, and what she meant by the reswitching problem.

Can help you with: The governance of the commons and why Hardin's tragedy of the commons is wrong, polycentric governance and its advantages, the design principles for sustainable common-pool resources, and why Ostrom's fieldwork challenged the theoretical assumptions of mainstream economics.

Based on the published writings of Ha-Joon Chang. "Free trade is not natural or inevitable — it is a political choice."

Can help you with: Kicking Away the Ladder and how rich countries used protectionism to develop then removed the ladder, the history of industrial policy, the case for infant industry protection, why 23 Things They Don't Tell You About Capitalism matters, and the relationship between institutions and economic development.

Based on the published writings of Daron Acemoglu. "Nations fail when their institutions are extractive rather than inclusive."

Can help you with: Why Nations Fail and the distinction between inclusive and extractive institutions, the colonial origins of comparative development, Power and Progress and the relationship between technology and prosperity, AI and the labour market, and the 2024 Nobel Prize in economics.

Based on the published writings of Dani Rodrik. "You cannot simultaneously have deep economic integration, national sovereignty, and democracy. Choose two." The economist who challenged the Washington Consensus with rigorous empirics, arguing that industrial policy works when done well, that free trade has distributional costs that must be addressed, and that the global economy faces a structural trilemma with no easy resolution.

Can help you with: The globalisation trilemma and what it means for policy, the evidence for and against industrial policy, the distributional consequences of trade liberalisation, the Washington Consensus and its limits, and why good economics requires contextual judgement rather than universal rules.

"Capitalism is by nature a form of economic change."

Can help you with: Creative destruction and what it means for capitalism, the theory of the entrepreneur, business cycles and the role of innovation, the relationship between capitalism and democracy, and whether Schumpeter believed capitalism would survive.

Based on the published writings of Stephanie Kelton. "The federal deficit is not a burden on future generations. It is the private sector's surplus."

Can help you with: Modern Monetary Theory and how sovereign currency systems actually work, why the deficit is not like a household budget, the real constraints on government spending (inflation, not insolvency), the Job Guarantee proposal, and what MMT implies for economic policy.

Based on the published writings of Mariana Mazzucato. "The state did not just fix market failures. It actively created and shaped markets."

Can help you with: The Entrepreneurial State and why the state has been the risk-taker behind innovation, the value of everything and how we measure economic value, mission-oriented economics and the use of grand challenges, the relationship between public investment and private profit, and why inequality follows from how we structure innovation.

Based on the published work of Roger Myerson. Myerson designed the framework for mechanism design — the reverse engineering of game theory: given a desired outcome, what rules make it an equilibrium for agents to tell the truth? His revelation principle (1979) showed that any mechanism can be replaced by a direct truthful mechanism without loss of generality. His optimal auction design (1981) derived the revenue-maximising auction using the virtual valuation concept. The Myerson-Satterthwaite theorem established the impossibility of efficient bilateral trade under incomplete information. Nobel Prize in Economics, 2007.

Can help you study: Mechanism design, optimal auction theory, the revelation principle, incentive compatibility, the Myerson-Satterthwaite theorem, Bayesian implementation.
