The Markets

There’s a new kid in town: narrative economics.

Last week, Richard Thaler was awarded the Nobel Prize in economics. His work in behavioral economics and finance recognizes not all economic and financial decisions are made after rational reflection. In Nudge, he wrote:

“The workings of the human brain are more than a bit befuddling. How can we be so ingenious at some tasks and so clueless at others?…Many psychologists and neuroscientists have been converging on a description of the brain’s functioning that helps us make sense of these seeming contradictions. The approach involves a distinction between two kinds of thinking, one that is intuitive and automatic, and another that is reflective and rational.”

Yale professor Robert Shiller, another Nobel laureate in economics, is exploring a field of study related to Thaler’s. It’s called narrative economics. Narratives are the stories we share with each other. They are fuel for conversation and popular narratives often become viral. During a presentation at the University of Chicago, Schiller explained narrative economics is “the study of the spread and dynamics of popular narratives, the stories, particularly those of human interest and emotion, and how these change through time, to understand economic fluctuations.”

Today, a popular narrative in financial circles focuses on Professor Shiller’s cyclically-adjusted price-earnings (CAPE) ratio, which suggests the market may be overvalued. Barron’s reported, “The CAPE, which is based on average inflation-adjusted earnings over the trailing 10 years, stands at 31, versus 32.5 in 1929 and 44 in late 1999.”

If stocks are overvalued, why do investors keep buying shares? It’s a question narrative economics hopes to help answer in the future.

Self-driving cars, life-like robots, artificial intelligence, and video phones.

Millennials and members of Gen Z may find the original Blade Runner movie a bit dated. After all, many of the tech innovations imagined have become a part of our daily lives and others, like mood organs, are in the works.

Mood organs were among the human enhancements imagined by Philip Dick in Do Androids Dream of Electric Sheep? (The book upon which Blade Runner was based.) A recent c|net.com article explained:

“Dick doesn't describe the design of the mood organ or how it works, only specifying that it can stimulate or sedate the user's cerebral cortex. Users simply dial up the emotion they want, such as 481 (awareness of the manifold possibilities open in the future) or 594 (pleased acknowledgement of a spouse's superior wisdom).”

Neural implants are a reality already, although they’re not used to control human emotion. Thousands of people with Parkinson’s have implants to manage tremors and applications to help with epilepsy and depression are being explored, according to IEEE Spectrum.

Medical treatments are not the only applications for neural implants. Elon Musk is developing ‘neural lace,’ a brain-computer interface (BCI) that may be injected into the human body, travel through the bloodstream, and settle over the cerebral cortex. While neural lace someday may be used to treat or diagnose neurological issues, The Economist reports Mr. Musk has argued, “human beings need to embrace brain implants to stay relevant in a world which, he believes, will soon be dominated by artificial intelligence.”

Musk is not the only entrepreneur pursuing brain interfaces. IEEE Spectrum reported Mary Lou Jepsen, an MIT alumnus and tech executive, has founded a company which is working on non-invasive BCIs “for imaging and telepathy (the latter could conceivably be done by reading out thought patterns in the brain).”

It’s possible the idea of humans with superpowers may seem quaint to future generations.

Weekly Focus – Think About It 

“The real question is, when will we draft an artificial intelligence bill of rights? What will that consist of? And who will get to decide that?”
