Why Economists Failed to Predict the Financial Crisis and the Evolution of Economic Thought

The podcast delves into the fundamental reasons why economists largely failed to predict the 2008 financial crisis, positing that the discipline's internal rules and methodological biases were key culprits. It argues that a rigid adherence to statistical analysis focused on population averages, rather than the critical 'tail-end' outliers exemplified by events like the Long-Term Capital Management collapse, prevented a holistic understanding of systemic risk. Furthermore, the compartmentalization of economic subfields created 'sins of omission,' where crucial insights from areas like finance were not integrated into broader macroeconomic predictions.

A significant portion of the discussion introduces 'identity economics,' a more modern and expansive view that redefines economic decision-making. Identity is presented not as a fixed attribute but as the 'stories that we tell ourselves,' which are profoundly shaped by the social networks we inhabit and the perceived expectations of others. This perspective challenges traditional rational choice models by emphasizing the social construction of preferences and the influence of narratives on individual and collective behavior, leading to a more 'fun' and realistic understanding of economic agents.

The speaker provides a compelling practical example of this evolving economic thought through the successful government policy on tobacco control in the United States. By leveraging the Surgeon General's report to establish a powerful narrative—'smoking is stupid'—the government effectively shifted social norms and reduced smoking rates without directly infringing on individual liberties. This multi-stage process, involving legal challenges, advertising bans, and the eventual social stigmatization of smoking, illustrates how influencing the 'stories' people tell themselves can lead to significant public health outcomes.

Ultimately, the podcast advocates for a paradigm shift in economics, moving beyond its traditional boundaries to embrace interdisciplinary insights from sociology, psychology, and behavioral science. This evolution, though initially met with resistance (as the speaker recounts with his own work on asymmetric information), is presented as essential for developing more robust models capable of predicting complex events like financial crises and addressing societal challenges like obesity. It suggests that a future-forward economics will be one that acknowledges and models the dynamic interplay between individual narratives, social influence, and collective decision-making.

in order to predict the crisis we needed to join many several different subfields of economics and the rules as to what you can and cannot write in economics makes it very difficult to do that

what economics is supposed to be about is it supposed to be about science we're supposed to do science and what is science supposed to be the way economists interpret science is you're supposed to do statistics

if you want to predict a crisis where the crisis was going to come from wasn't from a population it was from the tail-end of the population

there's some things which are what I call sins of omission the sense of omission are areas where in fact our methodology keeps us from doing things like predicting the financial crisis

identity is really a code word for the fact that people are telling themselves stories and when you tell yourself a given story that determines how you're going to think and what what what you're going what your decisions are going to be

the stories that we tell arise from the networks of people we associate with it partly because because of their views of how we should behave and our views of how we faith faith we think that they think we should behave

that five hundred page report can be summarized in three words smoking is stupid

I feel this is this is a major role is take a look at any major city or you know maybe not even major cities what you see is you you go past office buildings and what you see outside is you see these few people who are smoking their cigarettes and what you do is if you're a nonsmoker what you do is you pass them by and you get them a slight stare

when I first wrote my paper on asymmetric information that was considered so radical that it was simply not to be considered
