I work on the determinants of financial markets liquidity and volatility, the industrial organization of these markets, and their effect on the real economy. My most recent papers are on OTC markets, the implications of new technologies to produce and share financial information (AI), and the determinants of stock price informativeness and its effect on firms’ decisions (investment, product choices etc.).
