Summary of Project Results


The purpose of this project was to revisit an intriguing finding. Although over the last few decades leading up to the financial crisis there was a marked reduction in the volatility of aggregate output and inflation, there appears to have been a corresponding increase in the volatility of individual firms.

Here we argue that this apparent increase in firm level volatility was due to an increase in churning of firm activity in the form of acquisition and disposal of businesses. This created an increase in negative covariances between firms, so while the volatility of underlying organic growth has also fallen, observed volatility has risen.

We used a large set of observations on quoted US firms from 1950 to 2015, and data on acquisitions and divestitures from 1982 to 2014 to examine the relationship between firm volatility and the market for corporate assets.
