Do firms react to data breaches by investing in cybersecurity talent? We assemble a unique dataset on firm responses from the last decade, combining data breach information with detailed firm-level hiring data from online job postings. Using a difference-in-differences design, we find that firms indeed increase their hiring for cybersecurity workers. While this effect is statistically significant, the economic magnitude is small, which is consistent with firms’ lack of incentives to improve their cybersecurity infrastructure. Further, we collect data from the MIT MediaCloud and Google Trends to measure media and public attention following breach events. We find that firms with greater media and search attention after a breach are three times as likely to post a cybersecurity job. This provides evidence of market failure in cybersecurity investment that can be attributed to information asymmetries, and suggests additional scrutiny can ameliorate this market failures. With an increase in both the value of data as well as the number of cyber attacks, our research provides important insight into how media coverage and public attention can provide proper incentives for firms to make substantive, instead of symbolic, IT investments to safeguard their customer data.
