This project aims at exploring the implications of Covid-19 for economic development, with particular insights on green growth alternatives and social development. When we could have thought sustainable development was economically suboptimal, our Economics degrees proved us the opposite. Convinced that economic development and sustainable growth work in pairs, we want to explore the potential window the Covid-19 crisis might have opened in terms of responsible growth. Through comparative local investigations of developing and developed countries, our project aims to provide a comprehensive economic response showing that long-term growth can be (and has to be!) thought alongside with sustainable development. We believe this is the perfect time to launch our research given the challenges triggered by the Covid-19 outbreak. The latter is likely to foster a significant rethinking of our ways of development. Thus, our research will also investigate how, in the wake of the Covid-19 pandemic, developed countries might have changed their initial development approaches towards more socially optimal solutions. Our project will focus on a comparative analysis of sustainable and socially responsible projects both in resource-limited economies and richer countries. We seek to explore how they can learn from each other and be implemented at different scales.
