Being able to prove who you are is a powerful tool that can serve as a basis for exercising rights like voting, accessing financial services and receiving transfers, and reducing fraud. Yet billions of people in the developing world lack a means to officially identify themselves. In this week’s Wonkcast, Alan Gelb and Julia Clark draw from their ongoing research on biometric technology and development to explain how developing country governments and donors can tap advances in biometrics to help empower poor people.

Industrial policy—an active government role in shaping the direction of the economy—is often disdained by Western-trained economists but frequently embraced by Asian policymakers. Is it the path to development success or a slippery slope that leads to development failure? “New Structural Economics: A Framework for Rethinking Development and Policy” by World Bank chief economist Justin Lin and contributing authors provides a timely opportunity to review the evidence. Are systemic reforms to strengthen the business climate enough? How can policymakers guard against the well-known risks of favoring specific sectors or firms? Is there such a thing as a "New Industrial Policy" and can it provide useful guidelines for developing countries? This debate is of particular interest for low-income countries in Africa and elsewhere and the advice provided by their development partners.

In developed countries, official identification systems are a fact of life, providing the foundation for a myriad of transactions including elections, pension payments, and the legal system. Without functional ID systems, citizens of many developing countries miss out on the benefits of official identification. On this week’s Wonkcast, I am joined by CGD senior fellow Alan Gelb who has been researching the potential for new biometric technology, such as computerized finger printing and iris scans, to help poor countries leapfrog the long and complicated process of setting up ID systems.

In our conversation, Alan explains the depth of the problem in the developing world. “In most rich countries there are already identity systems that work more or less well,” he says. “In many poor countries, not only is there no consistent identity system but at least half of the people don’t have records of birth at all. They simply don’t exist.”
