Profile

I am a behavioral and experimental microeconomist. I study how institutions shape what people know and do, and how behavioral insights can inform their design. My work has two main strands. The first asks how political information is passed on, acquired, and processed, from the facts people choose to share to the platforms they search on. The second studies the behavioral design of markets and institutions, from auctions to second opinions in surgery and stem-cell donor registries. I combine theory with experiments in the laboratory, with professionals such as physicians and journalists, and in the field. I also apply causal inference methods to administrative data.

Education

I hold an MSc in Statistics from the London School of Economics, where I received the Royal Statistical Society Prize for Best Graduate, and an MSc and BSc in Economics from the University of Cologne, all with Distinction.

Job Market Paper
Curating Political Information: Who Shares What with Whom?

Draft

Why do people supply information slanted toward their own positions? In four experiments, I investigate whether this slant reflects deliberate selection, which motives drive it, and how it affects those receiving information. People curate the truth, choosing which facts to pass on and to whom. Even with the usual explanations ruled out, they value sharing facts that support their own political position beyond anything they expect those facts to do to others. They also want to correct and persuade others. However, they share less with those who hold different views on policy, even though their own expectations give them strategic reason to share more with them. When receivers make real political donations, people select more on expected persuasion. Professional journalists select in a similar way, even without market or newsroom pressures. Individuals from whom facts are withheld end up with less accurate beliefs and barely notice the selection. Selection among true information thus distorts what people believe without any falsehood, at a margin current policies such as fact-checking do not target.
