Dr. Sumeet Gulati is an Associate Professor in Environmental and Resource Economics at the University of British Columbia, studying the economics of urban transportation. Along with his co-authors he asks: at their modest values, do carbon taxes reduce gasoline consumption? Do they encourage people to buy fuel efficient vehicles? Do older consumers, especially women, perform better or worse while negotiating a price for a new car? What are the economics of car sharing—like Car2Go, and Evo? And what explains the autonomous emergence of electric rickshaws in India?
