Standard economic theory assumes a concave utility function, but that is inconsistent with today's rise in financial nihilism.
A concave utility function implies risk-aversion. Instead, we are witnessing increasingly higher and broader risk-seeking behavior, especially among young adults. Whether it be from high inflation, a shift in life goals due to social media, or the threat of AI taking jobs.
Instead, I believe the utility function of many young adults today follows an S-shape around a threshold T:
- Threshold T indicates the point of financial freedom or 'escaping the matrix'
- The function is convex below T, implying risk-seeking behavior
- The function is concave above T, implying risk-aversion: each additional unit of money contributes less to total utility/happiness
- We can also add a lower bound Umin, indicating a floor on overall utility/happiness due to the social welfare state (particularly in the Western world)
Such a utility function would more accurately describe the behaviors we are seeing today, and would suggest that financial nihilism is in fact rational.
