Hello, I am currently in a French agronomy engineering school and, as I am completing a Master's Degree in Environment Economics, I am seriously hesitating (as many people I believe...) about undertaking a PhD in Economics, or Natural Resources Economics, next year. I am really fond of economics and I have loved craming on economic subjects, but even if I would enjoy working on a research topic for 3 years I know from now that I don't want to pursue in an academic career but rather in the private sector or international organizations. I would like to work on development economics and/or natural resources economics. Teachers and researchers told me that a PhD was an international added value on the CV even for entering a firm or an international institution, and encouraged to do it in the US because it would be pretty much more valuable in the world afterwards. But I'm facing big diffuclties to evaluate whether it is worth it or not to "lose" 5 years of my potential professional life by doing a PhD whereas I don't want to be a researcher. I can't see if it is worth it more for elitism reasons than real utility. Considering my future ambitions, is it really useful ? Does that make a significant difference for recruitment ? Or is there another training (shorter !) that would give me the same opportunities in consulting firms or else ? Thank you very much
