I am a postdoctoral researcher at the University of Oslo. I'm affiliated with NorMER and CEES (Department of Biology), and the Department of Economics. My work centers around humans and their inter-relations with the social and natural environment.
I was born in Hamburg, Germany, in 1981, grew up in Tübingen, and studied International Relations in Dresden and Economics in Oslo. I lived at a number of different places for a shorter or longer while, the most important to me were Berlin, La Réunion, Dar-es-Salaam, and New York City. I have just moved within Oslo and now enjoy a little garden with my small family.
I derive analytic solutions for a dynamic game, showing that the first-best can be sustained in a non-cooperative equilibrium when the threat from crossing the threshold is large enough. When there are too many players and/or the prior on the threshold location is too pessimistic, extirpating the resource becomes a self-fulfilling prophecy.
We propose a method towards separating endogenous and exogenous influences on fish stock size and apply it to a long and detailed panel of Norwegian coastal vessels to assess the effect of introducing ITQs in the formerly open-access fishery for cod.
We apply basic search theory to the problem of a trophy hunter to endogenize the ``shooting decision''. Based on this, we develop an individual-based model to investigate ecological and evolutionary effects induced by hunting.
I develop a generic simulation model, calibrated on the North-East Arctic cod fishery, to highlight how the selectivity pattern, but also the specific biological modeling assumptions, matter for the resulting estimate of efficiency gains.
