The dynamics of firms can be understood by studying the properties of their growth rates. Although there has been a significant amount of work in trying to clarify the statistical properties of the growth-rate distribution, mimicking in many ways the tradition of studying the statistical properties of financial returns, a clear picture of their inter-temporal dynamics is still missing.
In this talk, I will present preliminary results on this topic. I will show that firms have an auto-correlated growth structure, but also that the structure of the correlations between firms shows a lot of interesting features –such as oscillations with non-trivial frequencies — whose origin is yet to be clearly elucidated.
