Even as flagging, high-profile hedge funds are looking for salvation in the quant world, academics are raising a red flag. Perhaps we’ve gone overboard in our efforts to reduce all financial activity to a set of numbers. For instance, Robert J. Shiller, in his presidential address delivered at the annual meeting of the American Economic Association at the beginning of this year, extolled the virtues of studying (admittedly quantitatively) popular narratives to understand economic fluctuations.
In Narrative and Numbers: The Value of Stories in Business (Columbia University Press, 2017) Aswath Damodaran, professor of finance at New York University Stern School of Business and a self-avowed numbers man, delves into the role of storytelling in the context of valuing businesses and making investments. Valuation, he claims, is a bridge between numbers and stories. “In effect, valuation allows each side to draw on the other, forcing storytellers to see the parts of their stories that are improbable or implausible, and to fix them, and number crunchers to recognize when their numbers generate a story line that does not make sense or is not credible.”
