We develop a novel firm-level measure of cybersecurity risk using textual analysis of cybersecurity-risk disclosures in corporate filings. The measure successfully identifies firms extensively discussing cybersecurity risk in their 10-K, displays intuitive relations with quantitative measures of...

Using textual analysis and comparing cybersecurity-risk disclosures of firms that were hacked to others that were not, we propose a novel firm-level measure of cybersecurity risk for all US-listed firms. We then examine whether cybersecurity risk is priced in the cross-section of stock returns....

In our paper “Cybersecurity Risk” (Florackis, C., Louca, C., Michaely, R. and M. Weber. 2023. The Review of Financial Studies, Volume 36, Issue 1, Pages 351-407; https://doi.org/10.1093/rfs/hhac024) we construct a novel firm-level measure of cybersecurity risk using textual analysis of...

Using China's Cybersecurity Law (CSL) as an exogenous shock, I examine how personal data security affects stock crash risk. I find that the stock crash risk of treatment firms (which collect personal data) significantly decreases after the CSL, and such decrease is larger when firms face greater...

We discover a novel flight-to-safety effect from cryptocurrency markets to stock markets. It occurs after a series of hacking attacks on crypto exchanges as greater uncertainty heightens investors' risk awareness and perception, which, in turn, induces herd-like behaviour in favor of safer stock...

Exploiting the staggered adoption of data breach notification (DBN) laws, which obligate firms to disclose data breaches when they occur, as an exogenous shock to data breach disclosures, we find that the adoption of these laws leads to higher future stock price crash risk. The positive relation...
