Macroeconomists for the Poor

John Grunsfeld, former NASA Chief Scientist and veteran of five Space Shuttle flights, had several chances to look down at Earth, and noticed how poverty can be recognized from far away. Unlike richer countries, typically lined in green, poorer countries with less access to water are a shocking brown color. During the night, wealthier countries light up the sky whereas nations with less widespread electricity look dim.
Dr. Grunsfeld’s observation might have important implications. Pictures from satellites could become a tool to help identifying where poverty is, by zooming in to the tiniest villages and allowing a constant monitoring that cannot be achieved with traditional surveys.
Achieving shared prosperity, one of the World Bank’s twin-goals, isn’t just a middle-income country’s preoccupation. It has a special resonance in Tanzania, a US$1,000 per capita economy in East Africa.
Tanzania has seen remarkable economic growth and strong resilience to external shocks over the last decade. GDP grew at an annualized rate of approximately 7 percent. Yet, this achievement was overshadowed by the slow response of poverty to the growing economy. The poverty rate has remained stagnant at around 34 percent until 2007 and started a slow decline of about one percentage point per year, attaining 28.2 percent in 2012. To date, around 12 million Tanzanians continue to live in poverty, unable to meet their basic consumption needs, and more than 70 percent of the population still lives on less than US$2 per day. Promoting the participation of the poor in the growth process and improving their living standards remains a daunting challenge.
