Recent finance literature highlights the role of technological change in increasing firm specific (idiosyncratic) and aggregate stock return volatility, yet innovation data is not used in these analyses, leaving the direct relationship between innovation and stock return volatility untested. The...

Recent studies find that idiosyncratic risk (IR)—the degree to which firm-specific returns are more volatile than aggregate market returns—has increased since the 1960s and attribute this to economy-wide factors such as the role of the IT revolution. Yet no innovation data is used in these...

Recent studies find that idiosyncratic risk (IR) has increased since the 1960's and attribute this to economy wide factors such as the role of the IT revolution. To gain further insights into why IR has increased over time, our paper uses industry level data and firm level data to study if...

Recent finance literature highlights the role of technological change in increasing firm specific and aggregate stock price volatility (Campbell et al. 2001, Shiller 2000, Pastor and Veronesi 2006). Yet innovation data is not used in these analyses, leaving the direct relationship between...

The paper studies whether “idiosyncratic riskâ€, i.e. the degree to which firm and industry specific returns are more volatile than aggregate market returns, is higher in innovative industries which are characterized by more risk and uncertainty. Volatility is studied both at the...
