[Publications] [Working Papers] [Work in Progress]

My research focuses on two main topics - markets and justice/fairness.
I analyze how decentralized markets work and are organized - from a theoretical, empirical and experimental point of view. I am interested in understanding how individuals pick the trading partners they interact with and how they learn about and judge available opportunities. Intermediaries can help buyers and sellers to overcome the obstacles and to explore the opportunities decentralized markets offer - I am investigating how and to what extent intermediaries enhance the efficiency in markets, among others, depending on the specific roles they assume in different markets.
One of my passions is art and the art market. I am looking into the role(s) art dealers assume in art markets, both nowadays and how the role of art dealers has evolved in the past, see also here.
My work on justice and fairness is dealing with procedural and distributive aspects - from a theoretical and experimental perspective. I am particularly interested in investigating how the terms "fair" and "just" are used in different contexts and how procedural and distributive fairness criteria are linked. Among others, I am doing experimental work on a criterion that has been important in the theoretical literature: envy freeness; it avoids comparing one person's happiness with another person's happiness - an inherently difficult and questionable task - instead it focuses on comparing bundles.
There are other topics that I am and have been working on and am interested in, such as learning, cooperation, trust, networks, ... see below for some of the results.
