Can solar and geomagnetic data help to predict French telecommunications' output (2000-2014)?

摘要

We examine the impact of solar and geomagnetic events on Earth's economic activity, and more precisely on the French telecommunications' sector, in the 2000-2014 time span. We find that the sunspot number and the Dst index have predictive and forecasting ability on the evolution of the French telecommunications' output. These results give credit to the impact of solar and geomagnetic events on the telecommunications' industry.
