The main topics are auctions, bargaining, and market design, including both theoretical and empirical studies. The auction and market design papers are primarily concerned with auction design, especially in communications, electricity, finance, health, and transport. The bargaining papers focus on the role of time and information in bargaining. There are also several papers on climate policy.
Market design involves bringing market innovations to practice. As such, in addition to my academic positions at the University of Cologne and the University of Maryland, I have a number of entrepreneurial and board activities that keep me close to practice. These activities complement my market design research in many industries (Innovative Auctions and Cramton Associates), including electricity, communications, transport, insurance (Tremor) and finance (CartaX).
