In the 1940s, economics started getting highly mathematical. It was basically because economists weren't smart enough to write down models of real behavior that they started writing down models of highly rational behavior - and they kind of forgot about humans.
Interpretation
Richard Thaler critiques the shift in economics towards overly mathematical models that neglect human behavior.
In this quote, Richard Thaler reflects on the evolution of economics in the 1940s, pointing out that the increasing mathematical complexity in economic models led to a disconnection from real human behavior. Thaler argues that economists, faced with the challenge of accurately representing the intricacies of human actions, opted for simplified rational models instead, resulting in a neglect of the essential factors that drive genuine human decisions.
In practice
During a lecture on the evolution of economic theory, one might use this quote to highlight the importance of human behavior in economic models.
The ability of businesses to monitor our behavior is already a fact of life, and it isn't going away. Of course we must protect our privacy rights. But if we're smart, we'll also use the data that is being collected to improve our own lives.
If you're trading individual securities, you're almost certainly making a mistake. Because most professional managers can't outperform their benchmarks, and there's little reason to think that individuals can.
When an economist says the evidence is "mixed," he or she means that theory says one thing and data says the opposite.
Academia does not provide many opportunities for immediate gratification. You work for two years on a project, it takes two more years to get it published, and then you start hoping someone might read it.
In the world of traditional economics, it shouldn't matter whether you use an opt-in or opt-out system. So long as the costs of registering as a donor or a nondonor are low, the results should be similar. But many findings of behavioral economics show that tiny disparities in such rules can make a big difference.
My thesis topic was 'The value of a human life.' I asked people a question: 'Suppose you had some risk, a one in a thousand risk of dying - how much would you pay to eliminate it?'
Adam Smith's 'invisible hand' is not above sudden, disturbing, movements. Since its inception, capitalism has known slumps and recessions, bubble and froth; no one has yet dis-invented the business cycle, and probably no one will; and what Schumpeter famously called the 'gales of creative destruction' still roar mightily from time to time. To lament these things is ultimately to lament the bracing blast of freedom itself.
America's downgrade may serve as a wakeup call for its policymakers. It is an unambiguous and loud signal of the country's eroding economic strength and global standing. It renders urgent the need to regain the initiative through better economic policymaking and more coherent governance.
With neoliberalism discredited and austerity failed, we need to rewrite the rules of the economy once again. But this time in the right way. We need rules that focus on long-term economic growth, and the only kind of sustainable prosperity is shared prosperity.
All wealth consists of desirable things; that is, things which satisfy human wants directly or indirectly: but not all desirable things are reckoned as wealth.
Speculators may do no harm as bubbles on a steady stream of enterprise. But the position is serious when enterprise becomes a bubble on a whirlpool of speculation. When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill done.
If you don't talk about families, then it's easy to disembody subprime mortgages and asset securitization and unemployment rates without remembering that every one of those numbers is a million families.
