At London Business School, we often try to explain the purpose of our existence by showing pictures of our students who are working on environmental issues in rural India or improving sanitation in a township in South Africa. We also always highlight the wonderful work of our Professor of Economics, Elias Papaioannou, on clearing landmines in Mozambique and the equally wonderful research by our marketing professor Rajesh Chandy on entrepreneurship in developing countries. And rightly so. These are admirable projects about issues that have a very direct and positive influence on the world.
