Indices that capture creative destruction: questions and implications

By Mariana Mazzucato and Massimiliano Tancioni


The paper argues that micro and macro economists interested in the dynamics of creative destruction can gain important insights by using indices that capture the effect of innovation on the relative position of firms. This is due to the uneven and 'destructive' effect that radical innovation has on firm rankings. One such index is the market share instability index. On the financial side, the excess volatility of stock prices and idiosyncratic risk also appear to capture the uneven dynamics of creative destruction.
