Nobel Laureate, Angus Deaton is having doubts about economics

Angus Deaton, Rethinking my Economics, Finance and Development, International Monetary Fund, March 2024.

Economics has achieved much; there are large bodies of often nonobvious theoretical understandings and of careful and sometimes compelling empirical evidence. The profession knows and understands many things. Yet today we are in some disarray. We did not collectively predict the financial crisis and, worse still, we may have contributed to it through an overenthusiastic belief in the efficacy of markets, especially financial markets whose structure and implications we understood less well than we thought. Recent macroeconomic events, admittedly unusual, have seen quarrelling experts whose main point of agreement is the incorrectness of others. Economics Nobel Prize winners have been known to denounce each other’s work at the ceremonies in Stockholm, much to the consternation of those laureates in the sciences who believe that prizes are given for getting things right.

• Power: Our emphasis on the virtues of free, competitive markets and exogenous technical change can distract us from the importance of power in setting prices and wages, in choosing the direction of technical change, and in influencing politics to change the rules of the game. Without an analysis of power, it is hard to understand inequality or much else in modern capitalism.
• Philosophy and ethics: In contrast to economists from Adam Smith and Karl Marx through John Maynard Keynes, Friedrich Hayek, and even Milton Friedman, we have largely stopped thinking about ethics and about what constitutes human well-being. We are technocrats who focus on efficiency. We get little training about the ends of economics, on the meaning of well-being—welfare economics has long since vanished from the curriculum—or on what philosophers say about equality. When pressed, we usually fall back on an income-based utilitarianism. We often equate well-being with money or consumption, missing much of what matters to people. In current economic thinking, individuals matter much more than relationships between people in families or in communities.
• Efficiency is important, but we valorize it over other ends. Many subscribe to Lionel Robbins’ definition of economics as the allocation of scarce resources among competing ends or to the stronger version that says that economists should focus on efficiency and leave equity to others, to politicians or administrators. But the others regularly fail to materialize, so that when efficiency comes with upward redistribution—frequently though not inevitably—our recommendations become little more than a license for plunder.

Rethinking unions:

Like most of my age cohort, I long regarded unions as a nuisance that interfered with economic (and often personal) efficiency and welcomed their slow demise. But today large corporations have too much power over working conditions, wages, and decisions in Washington, where unions currently have little say compared with corporate lobbyists. Unions once raised wages for members and nonmembers, they were an important part of social capital in many places, and they brought political power to working people in the workplace and in local, state, and federal governments. Their decline is contributing to the falling wage share, to the widening gap between executives and workers, to community destruction, and to rising populism. Daron Acemoglu and Simon Johnson have recently argued that the direction of technical change has always depended on who has the power to decide; unions need to be at the table for decisions about artificial intelligence. Economists’ enthusiasm for technical change as the instrument of universal enrichment is no longer tenable (if it ever was).
