open access: yesJournal of Financial Research, EarlyView.
Abstract I analyze differences between the core and extended trading sessions in the high‐frequency reaction of equity markets to potential news. Using presidential tweets as unanticipated, potentially market‐stirring events, I find that volatility increases and liquidity deteriorates within fractions of a second after a tweet.

On the measurement of electoral volatility

Mathematical Social Sciences, 2023
This paper introduces an axiomatic approach to the measures of electoral volatility between two consecutive elections, when these measures depend on the number of competing parties and the absolute value of the change in vote shares of the parties. The mathematical results on inequalities are in the basis of the theoretical developments.
