Welcome!

Welcome! I am Johanna Isman, a researcher at the Toulouse School of Economics. I obtained my Ph.D. in February 2024.

My primary research fields are environmental economics and empirical industrial organization. I am interested in studying the effectiveness of private and public policies tackling environmental, economic, and social issues in global value chains. My current work explores the economics of voluntary certification. I focus on the effectiveness of voluntary certification in regulating environmental externalities, such as the protection of carbon stock and biodiversity.
