I had the pleasure of being a jury member for the PhD thesis of Can Askan Mavi. Today was Can’s defence of his thesis, entitled “Essays on Environmental Policy under Catastrophic Event Uncertainty”, and it was a pleasure to have been there and  having had the opportunity to discuss the work. I would like to congratulate Can for his nice work and wish him all the best for his future career.He is now moving to SupAgro-INRA in Montpellier for a Postdoc position.

If you are interested in theoretical modelling of the impact of disasters and the relationship to the trade-off between adaptation and mitigation, then I invite you to take a look at his thesis.

The other jury members were Antoine Bommier, Professeur at ETH Zürich, Mouez Fodha, Professeur at Paris 1 Pantheon-Sorbonne, Katrin Millock, Charge de Recherche CNRS at Paris 1 Pantheon-Sorbonne, and Lionel Ragot, Professeur at Paris-Nanterre. The thesis director was Antoine d’Autume, Professeur at Paris 1 Pantheon-Sorbonne.


Could you please forward this job opening as “University Assistant“  to potential PhD candidates which is basically a fully funded post (4 years) associated with pursuing a PhD in Economics.

Thank you very much!

In the paper “Climate Policy Must Favour Mitigation Over Adaptation”, I develop the argument that the world must prefer mitigation to adaptation at the global level. The argument rests on the observation that mitigation is a public good while adaptation is a private one. I have the feeling that the academic literature has completely missed this point, and especially the representative agent literature, but also integrated assessment models that introduce adaptation and mitigation.

Read on for more details, why I have trouble to get this published in a journal, the referees’ comments and my rebuffals.

I am happy to announce that my article entitled “The Aggregation Dilemma in Climate Change Policy Evaluation” has been accepted for publication in the journal Climate Change Economics.

The article deals with the following question:

We show that a policy maker who ignores regional data and instead relies on aggregated integrated assessment models is likely underestimating the carbon price and thus the required climate policy. Based on a simple theoretical model we give conditions under which the Aggregation Dilemma is expected to play a role in climate change cost-benefit analysis. We then study the importance of the Aggregation Dilemma with the integrated assessment model RICE (Nordhaus, 2000).
Aggregating all regions of the RICE-99 model into one region yields a 40% lower social cost of carbon than the RICE model itself predicts. Based on extrapolating the results a country-level integrated assessment model would give a more than eight times higher social cost of carbon compared to a fully aggregated model. We suggest that these tentative results require researchers to re-think the aggregation level used in integrated assessment models and to develop models at much lower levels of aggregation than currently available.
