NICOLLE Ambre

After having received a Ph.D. in Economics from the University of Montpellier, I have been a Postdoctoral Researcher at the University of Munich thanks to the Marie Skłodowska-Curie COFUND action. I am now an Assistant Professor of Economics at ENSAI.

My research primarily focuses on the demand and supply sides in the network industries. I use structural approaches and observational data to model consumer behavior. I also use various reduced form approaches to comment on the development of prices and variety of products in markets subjects to an evolving competitive, regulatory and technological environment.

I have taught - and I teach - courses in Industrial Organization, Digital Economics, and Applied Econometrics.

I am a member of the Young Center for Advanced Studies of LMU Munich as well as a member of the French Association for Research in Digital Economics (AFREN).
