"This paper employs #computational #linguistics to introduce a novel text-based measure of firm-level #cyberrisk exposure based on quarterly earnings conference calls of listed firms.

The geography of cyber risk exposure is well approximated by a gravity model extended with cross-border portfolio flows. Back-of-the-envelope calculations suggest that the global #cost of cyber risk is over $200 billion per year."
