Marianne VERDIER

My research focuses mainly on the economics of platforms, with a particular interest in payment systems. My work aims at understanding payment platforms’ strategies, and their impact on competition and social welfare.
More recently, I have started to work on the topic of innovation and competition in the banking industry. In particular, I am conducting research on P2P lending platforms.
