Corporate management is often accused of short-term oriented behaviour related to R&D expenditures. This study analyses the influence of R&D volatility and R&D intensity on the market capitalization of pharmaceutical and medical research companies from Europe, considering the institutional...

We try to show the danger of confusing the concept of volatility with that of the standard deviation of a probability distribution. We work in the theoretical Black-Scholes model to give an explicit relationship between the two measures. We apply and then illustrate this relationship, firstly in...
