Dr. Ann-Kathrin Koessler


Behavioural Environmental Economics and Public Policy

The aim of my research is to generate a better understanding of human behavior in socio-ecological systems. I examine how pro-environmental behaviour can be motivated and strengthened, and what policy instruments are effective to do so. Currently, I am focusing on the question of how participation, self-commitment and empathy affect associated pro-social and pro-environmental behaviour.

In my research, I am employing experimental (lab and field), conceptual and theoretical methods.

Since November 2018, I am an IPBES (world biodiversity councilfellow and contribute to the report "Assessment of Diverse Values of Nature".

              This course aims to provide an understanding of the basic policy instruments how environmentally damaging behaviour can be regulated. Standard economic approaches as well as behaviour based interventions, such as nudges, will be discussed. The course is designed for an interdisciplinary audience and the language of instruction will be English.
