Mathieu Guigourez

PhD Candidate in Economics at Université Paris 1 Panthéon-Sorbonne, under the supervision of Dorian Jullien.
My PhD thesis is entitled Economic Rationality, Ecologic Responsibility.

Research

• My research revolves around conceptualizing an individual responsibility regarding ecological challenges without solely relying on monetary incentives or political enforcement.

• I am at the crossroad between ecological economics and philosophy of economics.

• For now, my main focus revolves around the methods of pricing carbon emissions and their normative assumptions. As such, I am studying the Stern-Nordhaus controversy around the discount rate and the optimal Social Cost of Carbon; and also in carbon taxes that seek to include a level of environmental responsibility.

• Besides, I am also studying the conceptualizations of individual commitments in Rational Choice Theories, emphasizing on climate-related issues.

• I am also interested in feminist epistemology and standpoint epistemologies.
