New York Times online
In this op-ed, UC Berkeley professor Robert Reich says that a buoyant stock market does not help workers, and discusses research co-authored by Prof. Martin Lettau, the Kruttschnitt Family Chair in Financial Institutions. Lettau found that from 1952 to 1988, economic growth accounted for 92% the rise in stock values, but from 1989 to 2017, economic growth accounted for just 24% of the rise in stock values.

With my colleagues, Martin Lettau of the U.C. Berkeley Haas School of Business and Sydney Ludvigson of New York University, I set out to investigate what makes stocks move over time. What we found was surprising.
Investing in a ‘Winner Takes All’ Economy
The Wall Street Journal online
