Are mobile phones revolutionizing development in Africa, or have they been over-hyped? My guest this week, Jenny Aker, says the truth is a little of both. Jenny is an assistant professor at Tufts University’s Fletcher School and a non-resident fellow here at the Center for Global Development. Her research interests include the impact of communication technologies in poor countries, especially Africa.

Mobile phone use has spread across Africa at a stunning pace. The percentage of Africans who could access a mobile phone leapt from only 10% in 1999 to more than 60% by 2008—far outstripping improvements in other infrastructure (roads, clean water, or indeed landline telephones). In a new CGD working paper, to be published later this summer in the Journal of Economic Perspectives, Jenny and her co-author Isaac Mbiti describe four main ways phones have been applied to the problems of the poor. In the Wonkcast, we discuss these four applications:

The American media is abuzz with stories of doom and gloom as tensions mount over stalled efforts to raise the U.S. debt ceiling. Europe, meanwhile, has its own debt woes, with mounting fears that a default in Greece could spill over into Ireland, Portugal and Spain. So far, however, there has been relatively little discussion about what these twin crises would mean for the 5 billion people living in developing countries. Sadly, those with the least influence over the issue could pay the highest price.

On this week’s Wonkcast, I invite senior CGD fellow and global finance expert Liliana Rojas-Suarez to explain why it’s important to the rest of the world that Europe and the United States put their financial affairs in order. The showdown in the U.S. is especially worrying, Liliana says, because of the U.S. dollar’s role as the international reserve currency.

 

Every year, billions of dollars are spent on food assistance to provide lifesaving sustenance to millions of people. That’s a lot of money, and an important cause, so it was encouraging to learn last week that the United States and the G-20 are starting to seriously scrutinize food aid policy. Recent developments in Washington and Paris show a growing consensus that it’s about time to overhaul outdated approaches to feeding the hungry.

Joining me this week to discuss these developments is Connie Veillette, director of CGD’s Rethinking U.S. Foreign Assistance Program and CGD research fellow Ben Leo. Having closely tracked U.S. and international food aid, both have concluded that reforms in financing, procurement and delivery can help ensure that food aid reaches more people who need it at lower cost.

For now, the future for Latin America looks bright. Confidence is high throughout the region after a strong rebound from the global financial crisis. But large and possibly volatile inflows of capital could lead to a credit bubble if regulators don’t take steps now to slow the large flood of hot money. In this edition of the Wonkcast I interview three members of the Latin American Shadow Financial Regulatory  Committee (CLAAF), a group prominent South American economists who meet twice yearly to offer advice to the region’s regulators and policymakers. Our focus is the group’s latest statement, which urges unconventional measures for extraordinary times.

Fallout from the killing of Osama bin Laden in a Pakistani garrison town has prompted an anxious reassessment of all facets of the complex, troubled alliance between the United States and Pakistan. A new report from CGD’s Study Group on U.S. Development Strategy in Pakistan shines light on a crucial and too-often neglected aspect of the relationship: the aid, trade and investment policies that constitute America’s effort to support Pakistan’s development.

The sudden resignation of Dominique Strauss-Kahn has sparked a global debate over the selection of the next head of the International Monetary Fund. French finance minister Christine Legarde, Europe’s nominee, has launched a round-the-world tour to promote her candidacy. Meanwhile, Agustin Carstins, the governor of the Bank of Mexico and the lone challenger so far to Europe’s renewed claim to lead the IMF, is seeking backing from European debtor nations and others by calling for greater flexibility in IMF bailout programs.

Against this background, CGD is pushing ahead with a survey on the selection process, qualifications and candidates for the IMF top job. I asked CGD president Nancy Birdsall, who has been arguing for a more open, merit-based selection process without regard for nationality, to join me on the show to share her views on the IMF leadership selection battle and the initial results from our survey.

Mohammed Yunus has been forced by a Bangladesh court to step down as the head of the Grameen Bank, leaving the world to wonder what will become of the institution that helped inspire the microfinance revolution. On this week’s Wonkcast, we consider the rise and uncertain future of microcredit, not so long ago the darling of development experts and activists alike, and discuss whether or not the arc of Yunus’s remarkable life serves as an apt metaphor for the microfinance movement.



My guest is CGD senior fellow David Roodman, who has been tracking the Yunus trial since it began as part of his Microfinance Open Book Blog. The book in public on the blog, Due Diligence: An Impertinent Inquiry into Microfinance, is nearing completion and will be published before the end of the year.

Dean Karlan and Jacob Appel present an new approach to global poverty reduction that combines behavioral economics with worldwide field research.Dean Karlan and Jacob Appel present an new approach to global poverty reduction that combines behavioral economics with worldwide field research. Their book takes readers into villages across Africa, India, South America, and the Philippines, where economic theory collides with real life. They show how small changes in banking, insurance, health care, and other development initiatives that take into account human irrationality can drastically improve the well-being of poor people. More Than Good Intentions provides a new way to understand what really works to reduce poverty; in so doing, it reveals how to better invest charitable gifts and official assistance to make a difference in the lives of poor people.
