At plausible rates of growth in population and income per capita, world GDP in
2050 could be four times what it is today. This paper considers the benefits this
growth can provide, the risks that it presents, and the building blocks required to
achieve it. The authors argue that “business as usual” risks unsustainable
outcomes. The alternative—responsible growth that sustains environments and
supports social development—requires long term thinking if it is to be achieved.
Dealing with near-term inequality, improving governance in developing
countries, and providing global public goods, particularly vaccine development
for tropical diseases and tropical agricultural research, will be key to attaining the
prosperous future the authors envision.
