Working Papers
Cyberattacks, Banking Stability and the Value of Supervisory Strictness, with C. Chiarella, P. J. Cuadros-Solas and L. Rossi
We study cyberattacks on U.S. banks and show that these events prompt stricter supervision. In turn, attacked banks become more prudent risk-takers and suffer less negative stock returns than peers during the 2023 banking turmoil.
Political Conflict and Corporate Policies: Evidence from the Basque Country, with F. Derrien, S. Hadjigavriel and A. Romec
We exploit the announcement by the Basque nationalist terrorist group ETA of the definitive cessation of its armed and extortion activities, and find that firms exposed to the extortion risk significantly increase their cash holdings and exhibit higher cash flow sensitivity of cash. They also reduce investment in fixed assets. These reactions are consistent with a shift away from strategic liquidity minimization under extortion risk.

Governance effort reallocation by institutional owners, with S. Garcia and A. Remesal
