CERE welcomes Victor Champonnois from Aix-Marseille University and Benjamin Ouvrard from Laboratoire d’Economie Forestière. 

Victor ChamponnoisVictor, a doctoral student in Economics at Aix-Marseille University, France is visiting CERE for three months. His field of research is mainly application of quantile regressions in contingent valuation studies. This implies both simulations and real survey data to compare the performance of quantile regression and standard models for contingent valuation (CV) data such as censoring or heteroscedasticity. However, in his most recent research, he studies the behavior of respondents to valuation surveys who refuse to state their true preferences because they disagree with some features in the survey. Consequently, he is trying to study how this behavior is affected by the institutional context. For this, Victor employs survey meta-data to estimate the effect of corruption and trust in institutions’ so called “protest responses” to answer which aspect of the survey design that can prevent or enhance this effect.


- I chose to come to CERE because this is a leading research center in environmental and energy economics. Besides, there are many researchers working in my field, so I hope to get valuable feedback about my research. Not to mention, I have always wanted to visit Sweden so this is a great opportunity!

Benjamin OuvrardBenjamin, graduated from University of Strasbourg, France, is now doing a post doc in Laboratoire d’Economie Forestière (LEF) in Nancy, France. As a doctoral student, Benjamin worked on both theoretical and experimental aspect of the implementation of nudges in his thesis. Currently, as a post-doc, he is working on understanding what the determinants of forest owners are that makes them switch to wood ash to increase the productivity of forest. Further, he is interested in the study of environmental nudges because they can incentivize individuals to adapt their behavior towards the environment in a simple and costless way. In particular, contrary to an environmental tax, a nudge makes individuals react by themselves. Put differently, individuals may become aware that their current behavior is not “good” for the environment. This type of work is interesting because it adds some elements of psychology in our economic models of individuals’ reaction to a nudge.


- I decided to come to CERE, as I will conduct a choice experiment on Swedish forest owners during my post-doc. This work will be conducted together with Göran Bostedt. I hope that during my stay I will have the opportunity to discuss my research but also future collaborations with other CERE members, and to exchange ideas on my choice experiment study. I would really enjoy starting new projects as well! Outside my research life, I very much enjoy reading, and in particular thrillers. I also like going to the cinema.
